- Lunch was served in the small courtyard where Ma Yilong lived.
The main star on the table is of course the potatoes. Zhao Hao is going to boil the big potatoes to taste and the small potatoes to stew the beef.
What, where did the beef come from? This one is drowned, seriously.
The cattle in Kunshan County are really miserable. Diseases and accidents kill more than a dozen moos every day
"It's a pity that the tomatoes and peppers are not ripe yet, otherwise I would have fried eggs with tomatoes and diced spicy chicken, which would be perfect for rice."
While cooking, the cooking utensils in Mr. Meng He¡¯s kitchen attracted the attention of the two children.
"Master, come and see. Mr. Meng He's stove is amazing. It can boil water without even lighting firewood or fire." The two children ran in and dragged Zhao Hao to the kitchen to have a look.
Zhao Hao had no choice but to follow him and saw the kettle already boiling on the red brick stove.
There was really no fire under the stove, only a copper pipe made a faint sound to boil the water.
No wonder the two children were making a fuss. Anyone who saw this scene would shout invincible Oh no, it's incredible.
Zhao Hao asked someone to close the door, and the light in the kitchen dimmed, and a blue flame appeared under the stove, jumping happily at the mouth of the copper pipe.
"It turns out there is really a fire, and the monster has to be touched" The two children were so shocked that they were a little scared and asked: "Master, is this a witchcraft?"
"Nonsense, this is science!" Zhao Hao rewarded the two with two slaps. He was about to say that even if he doesn't understand this, he is worthy of being my apprentice? Only then did he realize that these two were still second grade elementary school students, so he sighed helplessly and patiently explained to them what biogas was.
The one Ma Yilong used was a hydraulic biogas digester developed by Xishan Island Research Center 04 based on Zhao Gongzi's "Elementary Chemistry" textbook.
It connects the latrine, pigsty and biogas pool into one. The biogas tank is buried shallowly underground and is a cylindrical concrete structure with a movable cover on the top, so that human and animal feces and kitchen waste can be directly swept into the tank for fermentation.
There is also a small water tank connected to the biogas pool through the air outlet pipe. When gas is produced in the pool, the pressure continues to increase, and the material is hydraulically pushed into the water tank, which causes the liquid level in the water tank to rise. When using gas, turn on the biogas switch, and the biogas will be discharged under water pressure, and the liquid level in the water tank will naturally fall back.
In this way, relying on the rise and fall of the material liquid in the water tank, the air pressure in the tank can be automatically adjusted when gas is produced and used. This ensures stable output of firepower.
This thing has no technical threshold. It relies entirely on organic matter to ferment in an anaerobic environment to produce flammable gases that can be used to boil water for cooking and lighting.
And the biogas slurry can also be used as pesticides, fertilizers and feed additives, and the final biogas residue is also a good fertilizer The fertilizer taken out from the biogas tank is three to five times more efficient than ordinary compost!
Another very important point is that because it is a confined space, it is not easy to breed mosquitoes and has no odor. It is a great weapon for maintaining rural hygiene. This plays an important role in eliminating common infectious diseases in rural areas such as schistosomiasis and hookworm.
Therefore, Qu Rukui, the director of Institute 04, felt that this thing was like a heifer flying on a plane - Niu Boyi went to heaven. I worked on it in my spare time last year. After there were no safety issues in the test, a few sets were installed at Kunshan Agricultural College. I wanted to hear the professional opinions of Ma Yilong and the agricultural technicians to see if there was any possibility of promoting it in rural areas. This is the only way from laboratory to factory production.
Ma Yilong and others also think this invention is great. But the problem is not small. First, copper pipes with valves are used to transport gas, and a simple glass pressure gauge is installed next to the water tank. The cost is too high, and farmers may not buy it.
No matter how many benefits you have, you can't stop people from having firewood everywhere. So it¡¯s definitely not possible if it¡¯s too expensive.
04The toilet switched to using treated moso bamboo instead of copper pipes. The barometer was also cancelled, and a pullable bamboo strip was installed in the water tank to judge the air pressure through the water level, which successfully reduced the cost.
Furthermore, the Agricultural College also found that this thing is good, but it smells very bad when burned, and it is uncomfortable if you smell it too much.
This is normal, because in addition to colorless and odorless methane, biogas also contains a small amount of hydrogen sulfide. When Zhao Gongzi visited the sulfur production on Iwo Jima, the smell of rotten eggs was also caused by this substance.
But it doesn¡¯t matter, just add a section of bamboo tube desulfurizer filled with activated carbon and iron oxide between the biogas pool outlet and the gas pipeline.
Activated carbon comes from retort wood and has a strong adsorption effect, which can make biogas purified. Iron oxide is rust and can react with hydrogen sulfide to form iron sulfide, leaving sulfur atoms in the desulfurizer. This is the most common high-efficiency desulfurization method.
And when the user notices the unpleasant smell, he only needs to remove the desulfurizer and ventilate it, and the iron sulfide will evaporate again.It reacts with oxygen and is reduced to iron oxide and sulfur, which can then be used again.
Until the desulfurizer turns yellow completely, you can contact the staff to come and change the material. This step is free since pure sulfur can be recovered from the desulfurizer¡
??~~
In short, the biogas with a desulfurizer installed is still very comfortable to use. Especially in the southern region where there is high temperature and humidity, a biogas pool can be used to boil water for cooking and lighting for a family of six.
Zhao Hao thinks that the next step is to find a few farms in the county and pilot it on a small scale to see what the feedback from farmers and workers is like. If there is no problem, it can be promoted in the thousands of farms under the group's jurisdiction, and this business alone will be successful. When thousands of farms use it, biogas digesters will become popular in Jiangnan, and it will be much easier to promote it to ordinary people.
Leaving the kitchen, the two children were curious and wanted to take a look at the biogas lamp. Shi Jizhi took them to the study. In fact, the biogas lamp is just to add a glass lampshade to the nozzle of another pipe. Of course, the effect is not visible during the day.
But according to Shi Jizhi, this lamp can illuminate the whole room as bright as day at night, which made the two children stunned. I think it would be so happy if I could study in this room So being a top student really deserves a beating.
Zhao Hao feels that the brightness of biogas lamps is only average, not as good as calcium carbide lamps. Shi Jizhi and others thought it was really bright because they had never seen what is truly as bright as day
The main brightness of later biogas lamps actually comes from the lampshade.
The kind of lampshade that emits dazzling white light when heated is made of linen gauze soaked in thorium sulfate. Flax is easy to get, but Mr. Zhao only knows that it is extracted from monazite. But he had never even seen monazite, and he didn't even know how to prepare it. So we can only let them blow a glass cover first.
In fact, it¡¯s the same without a cover. I haven¡¯t seen anyone add a cover to the candlestick. Therefore, the glass cover can be added to the exclusive edition package together with the copper pipe fittings and glass barometer, which is specially designed for big dog owners. Although the price is much more expensive, what the rich want is a feeling that the poor cannot afford. Without this feeling, he would not pay
??~~
After half an hour, dinner was finally served. The baby potatoes have a smooth and sticky texture, and the stewed beef is so fragrant that it will make the kid next door cry
Mr. Zhao took one bite and burst into tears of dissatisfaction. This is the smell of my hometown that I can¡¯t go back to.
"This thing can really be used as a staple food." Thanks to Mr. Zhao, Fu Shijizhi ate potatoes for the first time, and he couldn't help but be excited by the new taste.
"Well, it's better than corn." Ma Yilong nodded and said: "If the output is increased, maybe this thing can save the Ming Dynasty in the future."
Zhao Hao smiled and did not refute. The old gentleman is already at this age, so it is good to think this way.
He peeled small potato slices slowly. After calming down, he changed the subject and said, "By the way, there is something that I wonder if you have heard of, sir?"
"What's the matter?" Ma Yilong took a big mouthful of rice.
¡°This month, the group received reports from several counties in Huzhou and Jiaxing, saying that a terrible silkworm disease is spreading in farms.¡± Zhao Hao said in a deep voice, this was his real purpose today.
"There are two kinds, not one. And it's not this year, but the year before last." Ma Yilong swallowed a mouthful of rice, picked up the handkerchief and wiped his mouth and said: "It was first discovered by the silkworm farmers in Tongxiang County, Jiaxing the year before last. The silkworms were fine one day, but most of them were dead the next day. Even those silkworms that successfully formed cocoons produced less than half of the normal silk. However, the price of silk was low at that time, and no one except silkworm farmers would take it seriously. thing."
"Last year, silkworm farmers in Wukang County, Huzhou discovered a strange disease. Black dots appeared on some silkworms. This kind of silkworms wriggle slowly and weakly, are picky eaters and are prone to early death. If one is also found, it will spread quickly, and then A large number of silkworms also died." Ma Yilong was the most authoritative agricultural expert in Jiangnan and even the Ming Dynasty, and someone had obviously reported the situation to him long ago. He also continued to pay attention.
"But at that time, you Jiangnan Textiles were eager to collect less silk, so naturally they wouldn't reflect it to you." He sneered at Zhao Hao and said: "At that time, the people's harvest was bad, and your people only focused on collecting silk at low prices, and didn't care about the silkworm farmers at all. It¡¯s a tragic situation. This is the year when sea trade has opened up, and the demand for raw silk has increased sharply. Finally, we are concerned about silkworm diseases. What a kind person!¡±
"In the initial stage of the group, a lot of work was not done properly, and people's concepts have not yet changed." Zhao Gongzi said to himself, no wonder Ma Yilong always quarreled with me after meeting me so easily. It turns out that I have been dissatisfied with Jiangnan Textile for a long time.
He knew that with the profiteer style of Liu Zhengqi and his gang, he would definitely not complain if he was scolded. He could only say: "I will pay more attention in the future."
"Humph, of course, you are much better than those wealthy and ruthless wealthy people. But you can't compare with them, right?" Ma Yilong was happy to say it, so he accepted it and got back to the point: "Usually, Silkworm diseases will not be passed to the next generation. But these two evil diseases have come again this year, and their scope has suddenly expanded to six counties - in addition to Tongxiang Wukang, there are also four neighboring counties. Erupted."
"The spring silkworms in these counties are in vain. If we don't find a way to control them, not only the summer silkworms will be wiped out, but it will probably spread to all the counties in Jiaxing and Huzhou." He said with a serious expression: "Next year , it is possible that it will erupt throughout the whole of Jiangnan, and by then, you will have nothing to gain!" (Remember the website address of this website: www.hlnovel.com)?You are much better than those big dog owners who are greedy for wealth and have no mercy. But you can¡¯t compete with them, right? "Ma Yilong was happy to say it, so he just accepted it and got back to the point: "Normally, silkworm disease will not be passed on to the next generation. But these two diseases are evil, and they came again this year, and their scope suddenly expanded to six counties-in addition to Wukang, Tongxiang, there were also outbreaks in four neighboring counties. "
"The spring silkworms in these counties are in vain. If we don't find a way to control them, not only the summer silkworms will be wiped out, but it will probably spread to all the counties in Jiaxing and Huzhou." He said with a serious expression: "Next year , it is possible that it will explode throughout Jiangnan, and by then, you will have nothing to gain!"
