Abstract

The invention relates to a device for production of biogas by winter solar heating combined with ultrasonic assistance and belongs to the technical field of biogas fermentation devices. The device comprises a heat collector, a water tank, a heat accumulation tank I, a heat accumulation tank II, a biogas tank, a thermocouple I, a thermocouple II, a thermocouple III and a temperature controller; theheat collector is used for heating water in the water tank, the hot water in the water tank can also perform energy accumulation on the heat accumulation tank I and the heat accumulation tank II; theheat accumulation tank I and the heat accumulation tank II simultaneously can heat the biogas tank. The device provided by the invention has the benefits that solar energy resources are utilized forheating, so that environmental protection and energy conservation are realized, and the biogas tank is ensured to normally produce the biogas in winter; through the two heat accumulation tanks, the heat accumulation capacity is greatly improved; the heat recovery rate is high, the processing amount is large, the use is convenient, and the efficiency is high.

Description

technical field [0001] The invention relates to a winter solar heating combined with ultrasonic auxiliary biogas production device, which belongs to the technical field of biogas fermentation devices. Background technique [0002] At present, there are more and more large and medium-sized biogas projects at home and abroad, especially the mesophilic anaerobic fermentation of high-concentration materials is the development trend of large-scale biogas projects. Among the factors affecting the gas production rate of biogas fermentation, temperature is one of the key factors, and mesophilic fermentation is the most The suitable temperature is 35-40°C. However, in order to make the high-concentration biogas medium-temperature fermentation project operate at a constant temperature all year round, and maintain an efficient and constant gas production in winter, it is necessary to strictly control the temperature of the biogas fermentation liquid, and take appropriate heating and he...
