Due to the increase in the temperature in the greenhouse, the air bag of the soft biogas digester has been puffed up, Wei Minsheng looked at the manual of the biogas digester, and asked to discharge all the gas in the biogas digester when it is used for the first time. Wei Minsheng, who has a good knowledge base in science, knows that the first biogas is not pure, and there is some air, this situation is very dangerous, the combustible mixture gas reaches the explosion limit, once it encounters Mars, it is easy to explode, if that, his greenhouse will definitely be destroyed. If the air content is too high, it is not easy to ignite. Since the methane in the biogas is a toxic gas, Wei Minsheng discharged all the impure biogas produced for the first time into the outside of the greenhouse through the gas pipe.

After emptying the gas in the soft biogas digester, Wei Minsheng checked the connection of various facilities, pipelines and related accessories.

After doing this, Wei Minsheng took another look at the vegetables he had planted a few days ago and found that at the right temperature, some vegetable seeds had already grown a few leaves. Wei Minsheng told the villagers who took care of the temperature of the greenhouse according to the instructions about the precautions, when to water and how much to water, and then looked at the situation on the temperature and humidity meter, and found no problems, so he left the greenhouse and went to the power plant.

Wei Minsheng checked the situation of the power plant, and thought that there are no major electrical equipment at present, and the electricity should be enough, but if the computer study room is built and some electrical appliances are added, the electricity may be a little insufficient, and the fan should be built as soon as possible. Since this fan needs a solid foundation, it is certainly not practical to bury it directly in the soil, but fortunately there is still some cement left, and it is reliable to make a cement foundation. There is no production capacity of cement here, but under this mountain is Lotte Creek, and there is no shortage of river sand and pebbles, so simply let the villagers go directly to carry it, and they only need to bring cement in the future. In the future, it will be necessary to build a defense system at the mouth of the valley into the mountain, and it will be stronger to use concrete than to make it with stone, in which case the demand for river sand and pebbles will be greater, and it may be necessary to build a road and buy some construction vehicles. But there is not much timber left in the warehouse, and the former logging yard is far away from here, so simply let the villagers look around to see if there is a suitable cypress forest nearby, after all, the main timber that Shunda Wood currently needs is cypress, and the sales of other trees are not as large as cypress.

Thinking of this, Wei Minsheng handed over the matter of finding the cypress forest and transporting river sand and pebbles to the river. I went to the place where I dug the pond and took a look, and half of the circle I drew had been dug up, and the depth was only two meters, which was indeed inefficient by manpower alone, thinking about my own world, digging such a large pond, an excavator could do it in one day. It's better to transport some river sand and pebbles first, and when you find the cypress forest, you can go to cut the wood, and then bring the excavator over, anyway, you will need to use it to open the mountain and build the road.

Wei Minsheng went to see the water tank again, and every day Steward Wang arranged for two villagers to carry water here to ensure everyone's daily life. Wei Minsheng thought, since there is electricity now, wait for the dawn over there to buy a pumping machine, and then buy a set of pool water level controller, so that the water tank can be automatically replenished, at least two more laborers can be saved.

Wei Minsheng made a list of things that came to mind, including cement, things needed for computer study rooms, pumps, small excavators, dump trucks and other equipment, no way, now the foundation book, I can't afford to buy large equipment, first equip the small ones, and then change to the big ones when the funds are sufficient. returned to the rental house and sent the list to Liu Mengling, asking them to implement it as soon as possible according to the requirements of the list.

The next day, Wei Minsheng went to see the biogas digester again, through one night's gas production, the air bag puffed up again, pressed it, and felt that it should be okay, so he connected the biogas booster pump to the power supply, and put the insulation water tank that can hold 1 ton on the open space next to the biogas digester, and raised it with bricks. After looking at the instructions for the use of the water heater and the environment in the greenhouse, it seems that it is not feasible to put the water heater directly in the greenhouse, in case the greenhouse film is burned out is not easy to do, and the greenhouse is a closed space, if the exhaust gas after combustion is too much, it is not good for the health of the people working in the greenhouse, or it is more reliable to put it outside the greenhouse. It is not easy to install in other places, so Wei Minsheng simply installed the water heater on the mobile house next to it, tied it to the protective railing of the window with a rope, and then fixed it again after buying an electric drill. A tee was installed from the biogas pipeline after the desulphurization and booster pumps, and a separate biogas pipe was connected to the inlet of the water heater. After connecting the biogas pipe, Wei Minsheng went to look at the hot water pipe that Chen Xiaohua bought. Because Wei Minsheng has long known that it is no problem for this general water pipe to be cold, but hot water must be connected with a hot water pipe, and a special fuser is required to connect the hot water pipe, so Chen Xiaohua bought a set of fuser tools by the way when he bought a hot water pipe. I took a look at the manual of the fuser, the power is only 700W, fortunately, it did not exceed the maximum power of the inverter, after all, only the problem of lighting was considered at that time, so the inverter was selected as 3000W, only if you have money in the future, you can change to a high-power one.

Wei Minsheng according to the instructions on the use of the method, first tried one or two joints, from the appearance of the joints should not be a problem, first connect it and then say, if there is water leakage during use, it is a big deal to reconnect the leaking joint.

Since it was the first time to use a fuser to fuse the hot melt pipe, it was not very skilled, and it took an afternoon for Wei Minsheng to finally install the inlet and outlet pipes. In order to achieve circulating heating, Wei Minsheng installed a small water pump on the pipeline between the thermal insulation water tank and the water heater, as long as the water pump is energized, the water heater senses the change of water flow and begins to work, the heated water enters the thermal insulation water tank, and the cold water at the bottom of the water tank is heated by the water heater, and finally realizes the supply of hot water in the thermal insulation water tank at any time.

Wei Minsheng took a look at the working condition of the water heater and found that there was another problem to be solved, that is, if the biogas in the biogas digester was used up, the circulating water pump should stop working, otherwise the biogas slurry in the biogas digester would be easily sucked into the biogas pipe by the biogas booster pump and damage the related equipment. It is still necessary to buy an air pressure switch, which will automatically cut off the power supply of the circulating water pump when the pressure of the biogas digester is too low to stop the work of the water heater. At present, the only way to do this is to find someone to take care of it when the hot water is boiling, and if the air bag of the biogas digester is deflated, the power of the pump is turned off manually.

Since the mobile house is a container modification, the bathroom is not easy to arrange, Wei Minsheng saw that there were still some bricks left, this morning Steward Wang has arranged for a few villages to come back with some river sand, simply build a simple bathroom in the greenhouse, and the used wastewater will be discharged directly into the biogas tank, and the temperature in the greenhouse is more appropriate, and you can take a bath without a bath bomb in winter.

After thinking about it, Wei Minsheng asked Steward Wang to use bricks to repair two bathrooms, one male and one female, according to his own requirements. There was no door for the time being, so an old sheet was hung in the place where the door was installed. According to the temperature in the greenhouse, for two days at most, the cement in this bathroom is not afraid of water washing, and you can take a bath at any time.

On the issue of whether the bathroom is charged, Wei Minsheng struggled for a long time, first wanted everyone to establish the idea of paying when accepting any service, but thinking that everyone's salary is for the value generated, he is already a black-hearted boss, don't consider this little money, just treat it as a welfare.
