Alas, there is no other way. I can only exchange it for this one. Zhan Wuya's body hurts extremely. Although the high-quality Big Red Eagle is already last year's cigarette, the taste has not changed at all after he carefully preserved it.
This thing can accomplish a lot of things with just one flick. Now that a pack of it is being given away, Zhan Wuya is extremely distressed.
I found Ma Qianzhu, spent a lot of time talking, spent a lot of money and a pack of cigarettes, and finally got two bottles of refrigerant with the promise that he would be the first to try out the ice machine after it was built.
"Without p12, I can no longer play with angry dogs——"
"You can play with real iron - I will build a machine gun specifically for you in the future..." Zhan Wuya said perfunctorily and put two bottles of F12 into the bag.
After working hard all night and debugging and disassembling the equipment countless times, a large piece of white ice finally appeared in the condenser! Zhan Wuya and Liang Xin suddenly became more energetic - this thing can still work after all!
Zhan Wuya hurried back to the office to find his thermos cup, packed the first piece of ice and sent it to the Governor - with a piece of paper "Good News" attached on it, and then he went there banging gongs and drums.
.
Liang Xin called the canteen and asked the canteen to quickly bring some insulated boxes. The insulating materials in these earthen insulated boxes were kapok and cotton, and they were specially used to transport popsicles and fresh seafood from the Fengcheng ship.
In the end, this ice machine can produce about 2 kilograms of ice every hour. To be honest, the efficiency is a bit low. However, Liang Xin noticed that their insulation measures were too poor. If the ice making efficiency was improved, it would be better.
.
Everyone was very happy that the Work Energy Commission came up with such a thing. After all, it was inconvenient to transport ice from Bopu. Now that there is a thing, you can enjoy frozen food anytime and anywhere. Someone immediately suggested installing one in the canteen.
.Some people also suggested that they simply dismantle all the air conditioners in their hands and convert them into ice machines - there are only so many air conditioners anyway, and they are not good for anyone. They could simply dismantle them and make ice cubes for everyone to enjoy.
In fact, the demand for producing refrigeration equipment has been very high recently, not only in Ziminglou. The communication center needs ice to cool down the equipment, the explosives workshop needs ice to cool down to ensure production safety, the canteen needs to preserve food, and the Ministry of Health needs to preserve food.
Cadavers for dissection...
The number of refrigerators in the crossing group is really pitiful - no one had thought of this thing at the beginning. The cold storage on the Fengcheng ship is a little far away from Bairencheng, and the cold storage on the ship uses auxiliary engines to burn precious diesel to keep running.
Ma Qianzhu has always hoped that the Works Energy Commission can develop more economical refrigeration equipment than marine cold storage.
The Work Energy Commission has held several meetings on this issue. They have long found a relatively simple, feasible and economical way to achieve Ma Qianzhu's request, and that is the gas refrigerator mentioned by Liang Xin.
The so-called gas refrigerator uses gas heating to boil concentrated ammonia water. The evaporated ammonia vapor is cooled to condense and liquefy the water vapor in it. The ammonia condenses into liquid ammonia, and then mixes with hydrogen at the evaporator inlet. Due to the difference in partial pressure,
Ammonia diffuses violently from the ammonia liquid into hydrogen, which lowers the temperature of the evaporator and plays a role in refrigeration. After that, the ammonia gas is absorbed by the dilute ammonia water and becomes a concentrated ammonia liquid, and the remaining hydrogen gas returns to the evaporator. So the gas refrigerator is
It is heated by gas combustion and circulates ammonia, water, and hydrogen in the pipeline for cooling. The cooling temperature can reach as low as minus 40 degrees Celsius. It is extremely efficient.
Ammonia water is no longer a problem when the 800-ton ammonia synthesis system has begun initial operation. Hydrogen is a by-product obtained during the electrolysis of salt soda production process.
Using this principle, it is possible to create a small refrigerator at the level of a household refrigerator. According to the standards of the 20th century, the technical content of gas refrigerators is very low. However, in the Lingao industrial system in 1629, there were many realities in the manufacturing of small gas refrigerators.
The problems cannot be solved. Especially in terms of materials and processes. For example, the manufacturing and processing of refractory ceramics on the combustion head and the zinc alloy die-casting of the burner shell. None of these can be solved immediately. Furthermore, the box must be
Efficient insulation materials are also what they lack.
Since it cannot be made too finely, the Works and Energy Commission plans to build a large "gas refrigerator" to reduce the technical difficulty of manufacturing - small burners of refractory ceramics cannot be made, but large cast iron burners are always no problem - in fact
They are planning to build a gas cold storage.
This cold storage was first built in the canteen - the canteen itself has a sufficient supply of biogas, and now there is coal gas, which is abundant in fuel. As for the insulation material, kapok or cotton alone cannot effectively keep the heat, so Zhan Wuya uses the ancients
The most common way to store ice is to build a cold storage underground and use soil to keep it warm. In the past, several major ice cellars in Beijing used to store ice in the twelfth lunar month. The storage conditions were earthen kilns and the outside was covered with straw curtains.
After that, it is piled with soil and stored until the ice cellar is opened in the following summer. The loss of ice is so small that it can be ignored.
Lingao Construction Company first dug a rectangular cellar with one side open under a small slope in the farm. After compacting the ground and four walls, it paved it with porous bricks and added insulation materials to the inner walls.
The Industrial Energy Commission has neither foam nor asbestos, and the only natural insulation materials that can be supplied in large quantities in Lingao are kapok and diatomaceous earth. In order to ensure the effect, the Industrial Energy Commission has alternately laid multiple layers on the inner wall of the cold storage. All pipes are made of yellow
Copper parts. After the cold storage is installed, a layer of straw curtains is laid on it, and finally it is completely covered with thick soil. Only an entrance and exit channel is left connected to the ground. The channel is equipped with two layers of wooden doors inside and outside, and the door is equipped with thick
As for the insulation material, the people in the machinery factory tried their best to make it as close as possible to the door frame, and attached several layers of belts as sealing materials. The combustion chamber of the cold storage was set on the ground. The gas from the farm's supporting gas generator was used for heating. Lingao
It rained a lot, so in the end a house was built above the entire underground cold storage for shelter, and there were drainage ditches on all sides.
After the ignition, the cold storage ran continuously for 24 hours, which proved that the minimum cooling of this cold storage was minus 16 degrees, and it could be stably maintained at this level.
Everyone is already very satisfied with this. The theoretically possible minus 40 degrees Celsius is of no special significance to the Crossing Group. At minus 16 degrees Celsius, it can already store various fresh foods, make ice cubes, and produce various cold drinks for a long time.
Due to the construction of a cold storage that can produce large amounts of ice cheaply, it not only meets dietary needs, but also acts as an air conditioner to a certain extent - large ice cubes taken from the cold storage are placed in the house to allow them to melt naturally.
, this traditional cooling method soon spread in the dormitories and offices of travelers. In order to prevent everyone from rushing to collect ice, the planning committee issued ice tickets to everyone after careful calculation, except for individual travelers.
In addition to the daily quota of several kilograms of ice, each department has different quota standards based on needs.
Lingao Telecom's communication equipment room has finally become cooler - not only for comfort, but also to ensure the normal operation of the machinery and equipment. Since the beginning of summer, in addition to using enhanced ventilation to cool down, Lingao Telecom's units have adopted
The best way is to turn on the machine in turn to avoid accidents caused by excessive heat.
Aboriginal workers working in high-temperature environments also enjoyed the coolness of ice cubes. This treatment moved many workers very much - being able to use ice in the summer was a privilege for the rich, but now it is possible for ordinary people like them
Enjoy. Although the air-conditioning in the huge workshop can't withstand much heat. But as Xiao Zishan often said: "Sometimes the people just want the rulers to have a minimum attitude."
Due to the strong demand for ice, the Works and Energy Commission soon organized the construction of a second and third cold storage. Due to the accumulation of experience, the construction technology became more proficient, and the energy consumption of the cold storage further decreased, and the probability of failure
It is also greatly reduced.
With the completion of the professional cold storage for fishing in Bopu and the supporting gas station, under the order of the Planning Commission, the cold storage on the Fengcheng ship was declared to stop operating. After the shutdown of this large power consumer, the auxiliary engine of the Fengcheng ship was running.
It was also reduced to maintain the lowest power of the ship's own system to save fuel. After the cold storage shutdown, which had been running continuously for nearly a year, the Navy Club's influence on the executive committee dropped significantly, and Fengcheng Ship was no longer a member of some committee members.
I love going to places. This result is probably the most unexpected.
Of course, it is a pity to leave this cold storage idle. Another task assigned by the Planning Commission to the Industrial Energy Commission is to study how to use gas to drive the auxiliary engines on the ship to generate electricity so that it does not use stored diesel at all?
"Theoretically, of course it's possible." Zhan Wuya said with a smile, "In reality..."
"What, unrealistic?"
"It's not unrealistic, but it's unnecessary." Zhan Wuya said, "The ship can obviously connect to an external power supply."
Modern ships can completely use the power supply on the shore after entering the port, and the Fengcheng ship can also do it.
"To put it bluntly, as long as the installed capacity of the Bobu Power Station is expanded, there will be no need for the marine auxiliary engines on Fengcheng to continue generating electricity."
Zhan Wuya continued: "Of course, it is theoretically possible to use gas instead of diesel to fuel auxiliary engines to generate electricity, but the laying of pipelines is a big problem."
The implication is that it is unnecessary.
Xiao Zishan reminded him: The auxiliary engine is a large generator unit, and its output power is greater than all the pot camel machines in the entire Bobu Power Station combined. The planning committee of such a large generator unit would not allow it to stop running.
By then, maybe Bopu will have to rely on the Fengcheng wheel's auxiliary engines to generate electricity.
"Yeah, that's true. But I haven't really played with such a big piece of marine auxiliary equipment, so I don't know what to do with it."
"Anyway, this matter can be studied slowly, so don't worry." Xiao Zishan comforted him, "You'd better think about building a real gas refrigerator like this."
Xiao Zishan thinks that it won't be long before each traveler's house can be equipped with a small gas refrigerator - provided that gas pipelines can be safely laid into the house, and perhaps in the future, gas lights will be installed in indigenous houses.
As for the animal-powered ice machine that Zhan Wuya worked so hard to build, it was safely transported to Guangzhou. Then Mo Xiaoan received a telegram: "Quickly make a hot water bottle and a large-mouth thermos bucket." - Ice was made.
, but there is no place to store it yet.
Mo Xiaoan sighed, got up and went to the glass factory. He suddenly thought: In fact, thermos bottles are also a good trading commodity!
Making hot water bottles is already a piece of cake for the glass factory. Especially after they have mastered the mold blowing technology more skillfully, they have achieved a breakthrough in blowing molding, which was originally the most difficult. With the mold,
They no longer have to rely on the feel of the blowing workers' hands, and can produce hundreds or thousands of identical finished products.
The key to a thermos is the bladder, which is essentially a glass bottle with a hollow sandwich. When manufacturing, the technology of combining large and small bottles is actually used.
First, the worker dips a small amount of glass liquid into the glass liquid and blows it into a glass bubble. After cooling it slightly, the glass bubble is continuously dipped in the glass liquid and blown continuously. Then it is lengthened and quickly put into the mold.
Turn the air blower enough to open the model and create a bottle preform.
Then the glassworkers repeated the work, but the models used were smaller. In fact, in the glass factory, compressed air is used to blow the molds in batches. Now they have no compressed air available, so for the time being,
Do it manually.
Mo Xiao'an watched a young man named Huang Zhongshan skillfully blowing the preforms one by one. His movements were as smooth as flowing water, and he couldn't help but nod his head repeatedly.
"This is the fastest and best among the apprentices." Xiao Bailang sat on a wooden box wiping his sweat. He was now in charge of both the ceramics factory and the glass factory. He was roasted wherever he went.
"Be enlightened."
"It's a pity that even if you have the understanding, you can't make blown glassware."
So far, almost all the slightly more complex products in the glass factory are blown or molded. Workers in the glass factory have not mastered the technology to make various products by just blowing, scissors and pliers - because
Neither can the time-travelers themselves.
"We need to capture some European glassmakers!"
"There are no European glassmakers in Asia." Mo Xiao'an said, "Europeans who come to Asia are basically scum."
Xiao Bailang didn't say anything. He paid attention to the operation of the entire workshop to see if it was in order. The weather has been hot recently, and Ji Sixui was away from the factory for a long time to conduct trial production of the coal chemical plant. The labor discipline in the glass factory was somewhat lax.
.As soon as Xiao Bailang arrived at the factory, he rectified labor discipline.
Xiao Bailang did not engage in any political and ideological work, and directly arrested several foreign workers into the labor reform team - they were later released with the intervention of Wu De. However, the production efficiency of the factory was greatly improved in this way.
Now as soon as he glanced at it, the entire workshop fell silent.
"You can't do it like this." Mo Xiao'an couldn't help but remind him, "As long as you use coercion, people will not accept it."
"I know, I know both kindness and power are valued equally." Xiao Bailang said casually.
"Okay, let me ask the food factory to send you some kvass here."
"Chief, the gas station said it can deliver gas..."
"Okay. You can have someone bring it to you." Xiao Bailang put on his sunglasses and walked to the gas nozzles that had just been installed. There was a row of yellow copper nozzles. He waved his hand: "Let's get started."
Several workers unscrewed the valve, and red flames immediately spurted out from the combustion head. Xiao Bailang put on his thick labor protection gloves and carefully adjusted the flames until blue flames spurted out.
"Prepare the interface!"
Huang Zhongshan hurriedly brought over the two glass bottle preforms, one large and one small, that had just been blown from the annealing kiln with pliers. Xiao Bailang first burned the bottom of the large bottle and the neck of the small bottle with gas, and then used a blade to clean them.
Then he put the small bottle into the large bottle and filled three small pieces of cork between the large and small bottles.
Formally speaking, asbestos particles should be used, and the Works and Energy Commission can only temporarily use substitutes. Its function is to maintain an equal gap between the inner and outer bottles so that they will not shake. Another function is to strengthen the bottles.
Structural strength of the bladder. After the bladder is made, the only connection between the inner and outer bottles is the bottle mouth. After filling with water, the bottle mouth is easy to break. After inlaying asbestos, it is equivalent to adding three additional support points.
Then he heated the large bottle into the small bottle over the gas fire until it was in a semi-melted state. This critical step was about to arrive. With a serious look, Xiao Bailang pulled up the pliers to grab the semi-molten glass liquid, and carefully closed the gap at the bottom.
. This process seems simple, but it requires certain technical requirements for manual operation. It not only requires that the bottom of the bottle be sealed smoothly and tightly, but also a thin glass tube must be left. Modern thermos bottle companies use automatic bottom pulling machines.
Finish.
Xiao Bailang tried several times, but failed. His face was red from the gas fire. He put down the pliers and took a few breaths, and asked others to try. After struggling a few times, he finally sealed the bottom as required.
.
Next comes the silver plating process. The thermos bottle bile is plated with silver nitrate. The silver plating agent is injected into the bile wall through the small glass tube reserved at the bottom of the bottle. With the basic supply of three acids and two alkali, this is basically
It didn't matter. After pouring out the residual liquid, a layer of bright silver was left on the entire wall of the glass bottle, which was as shiny as a mirror.
The workers let out a surprised sigh. In fact, they had already seen the "secret skills" of the time travelers when making mirrors. There were some greedy eyes in the crowd looking at the residual liquid poured out of the bottle.
After silver plating, the workers poured distilled water into it, washed it and dried it. Xiao Bailang used a gas fire to burn the glass tube at the bottom of the bottle and then inserted it into the air extraction pipe - this simple air extraction machine.
The machine is designed and manufactured by Zhong Lishi. It is a very simple pumping type and can barely reach the level of rough vacuum.
While pumping the gas, use a gas fire to heat the outer bottle to promote the expansion of the gas so that the gas can be quickly pumped out. Of course, the home-made air pump cannot determine the status of the air pumping. Xiao Bailang had to use the most primitive method and try again and again.
