A kind of biogas pond temperature increasing adjustment device

Abstract

The invention relates to a biogas tank temperature increasing adjustment device, which belongs to the technical field of biogas tanks. The device includes a biogas generator, a solar photovoltaic group, a solar heat collector, a thermoelectric generator, a power selection switch and a central controller; There is a heating rotating shaft, a rotating motor unit is installed on the outside, and a heat sink is installed on the inner bottom; the solar photovoltaic group is connected to the battery one; the solar photovoltaic group, the battery one, the power selection switch and the central controller are electrically connected in turn; A heating water tank is arranged under the device, and the heating water tank is connected with a water inlet pipe and a water outlet pipe connected with the heat sink; the water inlet pipe and the water outlet pipe regulate the hot water circulation through the water pump on it, and generate a temperature difference in the thermoelectric generator to realize power generation. And stored in the second storage battery; the biogas generating pool is equipped with internal and external temperature sensors electrically connected to the central controller; the central controller judges and starts the corresponding control mode according to the received signal, so as to realize the temperature increase in the biogas generating pool.

Description

technical field [0001] The invention belongs to the technical field of biogas pits, and in particular relates to a biogas pit temperature increasing and regulating device. Background technique [0002] Biogas is a combustible mixed gas produced by the decomposition of organic matter by microorganisms under suitable conditions. The biggest advantage of biogas compared with other biomass energy is that on the one hand, biogas is a relatively clean energy with high calorific value. On the other hand, the biogas slurry and biogas residues produced by biogas fermentation can be reused to replace chemical fertilizers and pesticides, which maximizes energy utilization efficiency. The damage to forest resources is estimated to be 8m 3 Household biogas digesters can use 0.13-0.20hm per year 2 Forest resources are protected from deforestation. Therefore, using biogas to replace coal, straw and firewood is an effective way to save resources. Therefore, in many ways of energy utiliz...
