The application of biogas is becoming more and more widespread. The scene of “the old manure was full of courtyards, and the use of firewood to cook rice and smoked people's eyes†has rarely appeared. Biogas has also become an important energy source for new rural villages under the vigorous publicity and advocacy of township governments. . However, there are still many problems in the biogas production mechanism and the daily management experience of biogas digesters. In particular, since the winter, temperatures have dropped, new digesters have not produced gas, gas production has been unstable, and gas production has been slow. This has affected users' use of gas and fertilizers, causing unnecessary losses to users. This article takes the application of Gumbol Biogas Fermentation Agent in the biogas fermentation process as an example, and responds to many readers and biogas users' questions about the common problems of winter biogas during operation and how to solve the problems. First, why do not produce gas after the new biogas digester feeds? 1. The water temperature of the feed liquid added to the biogas digester is lower than 12°C, which inhibits the life activities of the methanogens. In particular, cold seasons in the cold regions of the north, and the temperature of the pool is low, will cause long-term non-produced gas, and appropriate amount of warm water will be added when feeding. To increase the temperature of the hair. 2. Insufficient amount of inoculant was added during the loading process. The lack of methanogens in the tank prevented the biogas fermentation from proceeding and sufficient inoculum should be added. 3. The concentration of the fermentation broth in the biogas digester is too large, which causes the acetic acid to accumulate a large amount of volatile acid and cause acidification of the feed solution. Adjust the pH of the fermentation broth with lime water. Second, what is inoculum? Why add enough inoculum? Biogas-enriched substances added to biogas digesters are collectively referred to as inoculants. Because in general biogas fermentation raw materials and water, the content of biogas microorganisms is very small, and breeding on their own is not conducive to gas production as soon as possible. And hundreds of millions of beneficial microbial flora in Gumbol biogas fermentation can be cooperatively fermented with each other, so when the new pond is started and the old pool is refueled, the biogas fermentation bed and starting materials can be evenly mixed and added to the pool together. Effectively accelerate the start of biogas fermentation and increase the gas production rate of biogas digesters. Third, how to grasp the amount of feed? In the start-up and fermentation of biogas digesters, the appropriate concentration of the feed liquid should be mastered. The optimum fermentation concentration of the digester should be changed accordingly with the season (ie different fermentation temperatures). The general concentration range is from 6% to 12% and winter is from 10% to 12%. The amount of feed is too small, there are few effective substances, it is difficult to start and the gas production time is short; too much feed, is not conducive to the activities of biogas bacteria. The raw materials are not easily decomposed and the gas production is slow and small, so it is important to have a good grasp of the amount of feed. 4. Why does the gas production after the biogas digester charge less? How to solve? In winter, when temperatures are low, biogas digesters often produce little or no gas but do not burn well. The reasons may be two aspects: (1) The biogas pool is not strong enough to leak water or air leakage, and gas pipeline leak detection can be performed; (2) There is a lack of gas-producing beneficial microbial species, and there are many non-combustible gas components. Gem Biogas Fermentation can solve this problem very well. V. How to check gas pipeline leakage Main method: Close the digester main switch, disconnect the gas pipe connecting one end of the stove, and then pump gas into the gas pipe. When the pressure gauge rises to a certain scale, quickly close it. Indoor switch, observe whether the pressure gauge drops, such as the pressure gauge does not fall for 3 minutes, indicating that the gas pipe is not leaking. If you determine the location of the air can be used to blow air method, and then use a small brush dipped in soapy water, brush on the pipeline, there is a bubble in the place where the leak pipe, should be overhauled.
