A wind-solar complementary anaerobic
fermentation temperature increase heat-insulation device comprises a power supply
system and a
fermentation sealing tank, wherein the power supply
system is composed of a wind-power generator, a
solar cell array and a battery, which are respectively connected with a charging controller, the charging controller is connected with an
electric heating furnace tube, and a water inlet
pipe, a water outlet
pipe, a water
exhaust pipe, a water return
pipe and an air pipe are arranged on the
electric heating furnace tube, the inner portion of the
fermentation sealing tank is a fermentation
pool, the bottom of the fermentation sealing tank is provided with a bottom circulating pipe, one end of the bottom circulating pipe is connected with the water outlet pipe of the
electric heating furnace tube, the inner upper portion of the fermentation sealing tank is provided with an upper circulating pipe which is connected with the water return pipe of the electric
heating furnace tube with the other end, the fermentation sealing tank is provided with a feed inlet and a discharging hole, and the feed inlet and the
discharge hole are both provided with sealing covers. The invention can be used for anaerobic fermentation temperature increase and heat-insulation, and has the characteristics of wind-solar resources
complementation, higher resource availability ratio, lower cost, long service life, simple control and stable temperature increase and heat-insulation.
