Yan Shiyue was not polite, and directly in front of them, ordered Ding Xiaoyan to prepare limestone and white coal, then took the two of them to the study, and called the fourth prince: "Fourth brother, I told you to write."
The fourth prince was very proactive. He immediately rolled up his sleeves, sharpened his ink, and picked up his pen.
Yan Shiyue tried hard to recall and integrated the knowledge in his mind before saying: "In a flood-prone area, the most important thing is to prevent various diseases, so we must pay attention to disinfection."
Disinfection requires bleaching. The main component of bleaching is calcium hypochlorite. To prepare calcium hypochlorite, you need to first add limestone and white coal intermittently from the top of the lime kiln according to a ratio of 1: (0.11 to 0.13).
Entering the lime kiln
For calcination, the temperature needs to be controlled at 800-1200°C. The generated lime is intermittently discharged from the bottom of the kiln, and is digested with water to obtain slaked lime containing a small amount of free water. It is aged for more than eight days and sent to the air separation system for slag removal through the auger.
.
The powdered slaked lime undergoes gas-solid phase separation through a cyclone separator. Fine-grained slaked lime containing 3% to 6% free moisture is added from the fourth layer of the chlorination tower through the auger under the slaked lime silo, and **(** liquefies
The tail gas) is introduced from the first layer of the chlorination tower, and the bleached products are discharged from the first layer of the chlorination tower ①.
This process is very complicated for this era, and a lot of equipment needs to be researched and produced. No matter how urgent it is, it won't be ready in less than ten days and a half.
Therefore, at present, you can use simple boiling disinfection first.
Then, remember that diseases enter through the mouth, for example, do not eat drowned animals, do not eat soaked food, do not drink unboiled water... etc. You can just make up a rhyme and teach it to the people to sing.
In addition, disinfection of feces, corpses, etc., and post-disaster elimination of mosquitoes, flies, and rodent species are also top priorities.
She spoke a lot and was confused. After the fourth prince finished memorizing it, he exchanged glances with the prince. Both of them felt a little complicated.
Really, Princess Fuyan has never been expected or disappointed.
When it comes to disaster relief, the civil and military officials are called in. The first step is water control, such as reinforcing dams and diversion of rivers. The second step is, of course, diseases. We need to bring the imperial doctors there to figure out how to treat them, and then appease the people...
But what she said was "prevention", prevention and treatment of epidemics.
The prince pondered slightly.
The fourth prince took another piece of paper to sort it out. It was the first time he witnessed a miracle happen with his own eyes, and his expression was vaguely excited: "Is there more?"
Yan Shiyue thought carefully.
The first thing she thinks of is always modern disaster relief methods.
But isn’t there any merit in the ancient people’s disaster relief efforts?
Yes, of course there is.
Fan Zhongyan, a famous official in the Northern Song Dynasty, took several disaster relief measures at that time, which were very courageous and ingenious.
For example, he was the first to propose "relief for work".
She has always been in favor of this idea and has also discussed it with the Fourth Prince.
Moreover, he also encouraged the local area to hold more competitions, and he himself took the lead in participating and encouraged them. At the same time, he also summoned the hosts of various temples and told them that during the famine years, labor prices were the lowest, and the temples could take this opportunity to renovate the temples.
The hosts were convinced of this, so they seized this rare opportunity to recruit refugees to work. They only paid very little wages and provided three meals a day, and the refugees flocked to it.
Government officials, merchants, and wealthy families also saw the opportunity and started building construction projects one after another. The victims would have food to eat and things to do, and the situation would naturally become stable.
Also, at times like this, there is not enough food for disaster relief, and there will always be those profiteers who drive up prices, hoard goods, and want to enrich the country while the country is struggling.
He asked people to spread the word in surrounding prefectures and counties, saying that the price of rice in Wuzhong is now 180 wen per dou, and those who want to make a fortune should come quickly!
When businessmen from other places saw how profitable it was, they couldn't help but immediately organized a large amount of grain to be shipped over.
After countless grains were transported in, they competed with each other to lower the prices, and market leverage began to come into play. The high grain prices immediately fell back, which not only solved the problem of food shortage in the disaster-stricken areas, but also severely dealt a blow to those who tried to enrich the country.
profiteers.
What she said was still a bit confusing, but the prince and the fourth prince were shocked to the point of being speechless.
You know, a talented person may not be an official.
In this era, there are really very few people who understand economics.
Fan Zhongyan's economic thinking was also impeached by countless people at the time, accusing him of not being considerate of the famine government and indulging in fun and entertainment during the disaster, building large-scale construction projects, wasting people and wasting money, etc.
Including the crown prince and the fourth prince, they were a little confused at first.
But when she straightened out her thoughts and told the consequences, the prince and the fourth prince were not stupid, so they naturally understood.
After understanding it, all that was left was admiration.
Then Yan Shiyue was carried into the palace by the two men. Emperor Ming Yan couldn't help being shocked when he heard what the two men said in detail.
Let’s not talk about the “disinfectant powder”, but the subsequent measures are of great wisdom.
The key to raising money for events and building large-scale construction projects is to "employ people" and raise private financial resources to benefit the local area. It not only relieves disasters, but also helps the people. It has immediate results. It is very happy for the local people, and it is even more important for the court and the government.
Kill multiple birds with one stone.
If we say that in the past, disaster relief was provided by the imperial court to the people, but now, the imperial court has become a promoter and guide, fully deploying the local "surplus wealth" to appease the local people.
For him, this opened the door to a new world.
Moreover, Yan Shiyue who proposed these things really impressed him.
Emperor Ming Yan glanced at the little girl below.
She just yelled that she didn't have lunch, so she asked Gu Jiuxing to serve a bowl of noodles, and she was sitting by the window eating it, like a little squirrel.
Although she had many eccentric talents in the past, they were all more "technical". Only then did he discover that the things in her mind were indeed worth exploring.
It was at this time that he strengthened his determination to let Yan Shiyue enter the court. When he looked at her, he almost thought about what official position he would let her take.
Emperor Ming Yan smiled slightly and said: "Prince, go ahead. Si Lang, you organize the manpower to make this disinfectant powder. Yue'er, please help your fourth brother."
Yan Shiyue didn't notice anything was wrong at all and bit her face and responded.
Then the prince left first. She finished eating the noodles and left the palace with the fourth prince. She immediately organized people to prepare disinfectant powder.
The fourth prince has always been very hands-on in everything he does, and she also takes the lead in important matters. The two of them organized the manpower very quickly, and then rushed to make the cyclone separator and other equipment.
The two of them led a group of craftsmen and worked non-stop for several days. After several failures, they finally started production. They were relieved until they entered the aging stage.
Although the flood was a major event, it was far away after all, and life in Chang'an City continued as usual.
While having dinner, Yan Shitu asked Yan Chengyuan: "Dad, where are Yue'er and the fourth prince now?"
Before Yan Chengyuan could answer, Meng Min said: "Yue'er came back around noon today. She said she was here for dinner in the evening. Why hasn't she come yet?" While asking someone to hurry, she asked him again: "Why did you think of asking Yue?
