专利技术适应北方地区的沼气发生器因产生沼气的温度最低在12度以上,北方地区气温比较低,尤其在冬季,沼气池一般很难达到产生沼气的温度。本沼气发生器利用北方农村用土暖气取暖的方法与土暖气配套使用,以提高沼气池内的温度。按12立方米的沼气池, The patented technology adapts to biogas generators in the northern regions where the temperature of biogas production is at least 12 degrees, and the temperature in the northern regions is relatively low. Especially in winter, biogas digesters are generally difficult to produce biogas. The biogas generator utilizes the method of heating the soil used for heating the soil in the north of the country and uses the soil heating to increase the temperature in the biogas tank. Press 12 cubic meters of digester,
