Biogas storage technology

Biogas can be used not only for cooking and lighting, but also for grain storage. Because the content of methane and carbon dioxide in the biogas is high, the oxygen content is very low, and the methane is non-toxic. After passing through a closed container for storing grain, it can cause an oxygen deficiency state to control the respiration intensity of grain and reduce the matrix consumption during storage. It can prevent insects and mildew and achieve safe storage. The specific storage methods are as follows: In the concrete tanks, tile tanks, jars and other containers packed with dried rice, corn and other foodstuffs, use wood to do the pool cover or cylinder head, you can also use airtight plastic cloth cover, cover Drill two small holes, the size of the hole can be inserted into the gas pipe. One hole is inserted into the inlet pipe and the other hole is inserted into the exhaust pipe. If there are several containers, they can be connected in series by pipes. The air inlet pipe is connected to a switch, and then a bamboo raft inserted into the concrete pool or tile cylinder is covered, the cover is covered and then sealed with paraffin. When one end of the exhaust pipe is connected to the biogas switch and the biogas furnace, when the biogas is input, the switch on the exhaust pipe is opened so that the air in the tank and/or the cylinder can be discharged as far as possible until the biogas furnace can ignite, and then the intake and exhaust can be closed at this time. The switch on the trachea fills the tank or tank with biogas. About 5 days, you can kill corn pests, rice plunder, and mung bean pests in food. After testing, rice is 100% less pest-resistant and 4.71% more germicidal than the control group after it is stored in biogas for one year. Farmers may wish to try it.
