Abstract

The invention discloses a system and a device which produce methane by heating with electrical cartridge heater and solar energy. The invention solves the present problem that the structure which produces methane with a plurality of energy is complicate, the operation fees are expensive and the large scale application is difficult. The water outlet of solar collector and the first end of the second magnetic valve are connected with the water outlet of incubator, the water outlet of the solar energy collector is connected with the first end of the first magnetic valve, the second ends of the first magnetic valve and the second magnetic valve are connected with the water outlet of the circulating water pump, the water inlet of the circulating water pump and the water outlet of the incubator are connected with methane tank, the electrical cartridge heater is arranged in the incubator, two temperature sensors are arranged on the pipe of the solar collector and incubator, the control input end of the circulating water pump and two magnetic valves are connected with the control output end of the temperature controller, and the signal output ends of two sensors are connected with the signal output end of the temperature controller.

Description

technical field [0001] The invention relates to a device for producing methane through combined heating of solar energy and electric heating. Background technique [0002] Biogas technology refers to the use of agricultural waste to recover energy and produce other agricultural products. This energy is recyclable. my country is a large agricultural country. In recent years, the breeding industry has developed rapidly. The scale and number of livestock and poultry farms have continued to expand, and the discharge of livestock and poultry manure has increased dramatically. According to incomplete statistics, by the end of 2001, the total amount of feces and excrement water in the whole year exceeded 1 billion tons. In addition to the flushing water produced by intensive production, the actual sewage discharge has far exceeded this figure. The current situation in rural areas is that The application and promotion of biogas technology in rural areas of our country provides raw ...
