For daily management of the 100-kilowatt biogas generator and biogas digester used in the breeding industry, there are many things that need to be paid attention to.
1. Pay attention to the normal gas production in the biogas digester:
1. Replenish fresh ingredients in time
2. Discharge and stir frequently;
3. Frequently check whether the cover plates are fully covered;
4. Frequently observe the air pressure on the barometer;
5. Frequently check whether the transmission and distribution pipelines are leaking;
6. Frequently drain the water in the condensate collector to prevent water blockage in the pipeline;
7. Pay attention to heat preservation measures in winter.
2. How to do a good job of daily feeding and discharging of biogas generator and biogas digester in the 100-kilowatt aquaculture industry?
Generally, fresh raw materials should be added in time after the feeding of the new pond or the large-scale refueling of the biogas digester. Use the first discharge, the second charge, the amount of discharge, the amount of input, and the amount of material discharged. It is necessary to ensure that the liquid in the tank is liquid. The surface is higher than the inlet and outlet.
Three, the inlet and outlet of the material should be covered with protection
The depth of the biogas digester is generally close to 2 meters. At the same time, the fermentation room is in a sealed state. Once people and animals fall into the tank, it is very dangerous. Therefore, the inlet and outlet of the biogas digester must be covered with a strong cover plate (such as prefabricated cover plate, wooden board, etc.), which is safe, prevents the volatilization of ammonium nitrogen in the biogas manure, and is also conducive to maintaining And raise the ground temperature.
3. Identify whether the pH of the fermentation liquid is normal
Use a wide range of pH test paper for testing, and the normal value is between 6.8 and 7.5. It can also be identified simply by observing the color of the material at the outlet: the material at the outlet of the biogas digester for normal fermentation is soy sauce-colored and rich in foam; when the biogas slurry is slightly acidic, the material at the outlet is green, so stop feeding. When the material is restored to normal or take out a part of the raw materials, add water to reduce the fermentation concentration; if the material liquid at the outlet is black and white film, it indicates that the material liquid is acidified, and an appropriate amount of clarified lime water or plant ash should be added, and more Inoculum: If the material at the outlet is gray, it indicates that the concentration of the fermentation material is low, and fresh raw materials should be added in time.
4. How to stir the fermentation raw materials in the biogas generator of the 100-kilowatt farming industry biogas generator frequently
Frequent stirring of the fermentation liquid has three advantages:
1. It can make the fermentation raw materials and fermentation bacteria evenly distributed in the biogas generator of the 100-kilowatt aquaculture industry, and the anaerobic bacteria can fully contact the fermentation raw materials. In this way, the nutrition of anaerobic bacteria is good, so that it can grow and reproduce rapidly and increase the gas production rate.
2. It can break the upper layer of crusts, so that the methane produced in the middle and lower layers attached to the fermentation raw materials will accumulate from small bubbles into large bubbles and rise into the gas box.
3. The temperature in the biogas digester can be balanced. Therefore, it is very necessary to adopt stirring measures to break the stratification phenomenon and speed up the anaerobic digestion rate.
5. A certain amount of water should be kept in the 100-kilowatt farming industry biogas generator and biogas tank storage circle
A certain amount of water should always be kept in the water storage circle above the movable cover of the biogas digester to prevent air leakage due to dry cracking of the sealing clay, and to facilitate timely detection of air leakage.
