1. Start a new pool in winter. If it is difficult to ferment in winter, if it is forced to start a new pond in the winter, the effect of gas production is not good, which will have an adverse effect on the long-term use of the digester. Will produce less gas, or even gas production. Similarly, it is not appropriate to make large refueling in the winter.
2. The decrease of temperature causes the fermentation to stop. Temperature is the key to good or bad gas production, so the winter is the most prone to the decline in gas production. Once the temperature drops below 10°C, it will be difficult to ferment and the gas production will basically stop.
3, stratification caused the fermentation to stop. Due to the low temperature in winter, the temperature of many liquid substances in the fermentation raw material falls below the condensation point, condenses into a solid, causing the material liquid to be crusted or stratified, various fermentation raw materials are separated, and fermentation cannot be fully mixed.
4. Cracks in the pool wall cause leaks. If the winter temperature suddenly drops, it will easily cause cracking of the pool wall, which will greatly damage the life of the winter gas and the life of the digester, and must be taken seriously. If cracks in the pool walls are found, they must be repaired.
5, pipeline damage or water. Condensation water is more likely to form in pipelines during low temperature conditions in winter. If condensate water fails to enter the water collector and is trapped at the elbow, it can easily clog the pipeline, causing gas transmission difficulties. On the one hand, it needs to pay more attention to the elbow and easy accumulation of water. On the one hand, the condensate in the water collector must be removed in time.
