NOVELTY - A heating device with wind-power and solar photovoltaic generating complementation on a methane tank, comprises a solar cell (1) that is irradiated by the sunshine on a daily support frame (2) of a support frame base (3) to generate a direct current; where the direct current is input in a photovoltaic controller (5) by the lead wire (4) to regulate and input in a photovoltaic inverter (6) to be converted as an alternating current; and the alternating current is input in a photovoltaic temperature regulating device (15) in fermentation liquid of a fermentation chamber (17) of methane tank (19).    USE - The heating device with wind-power and solar photovoltaic generating complementation on a methane tank is useful for industrial applications.    ADVANTAGE - In the heating device with wind-power and solar photovoltaic generating complementation on a methane tank, the wind-light new energy source remarkably increases the temperature of the fermentation liquid in the fermentation chamber of the methane tank, promotes the growth and breeding of the methane bacteria in the methane raw material, and makes the methane bacteria accelerate the decomposition speed of the organic at the proper temperature environment to increase the yield of the methane.    DETAILED DESCRIPTION - A heating device with wind-power and solar photovoltaic generating complementation on a methane tank, comprises a solar cell (1) that is irradiated by the sunshine on a daily support frame (2) of a support frame base (3) to generate a direct current; where the direct current is input into a photovoltaic controller (5) by the lead wire (4) to regulate and input into a photovoltaic inverter (6) to be converted as an alternating current; the alternating current is input into a photovoltaic temperature regulating device (15) in the fermentation liquid of a fermentation chamber (17) of the methane tank (19) to convert the electric energy as the heat energy to radiate the heat energy; it properly increases the temperature of the fermentation liquid, promotes the growth and breeding of the methane bacteria, and accelerates the decomposition speed of the organic to increase the yield of the methane; the wind power above the ground blows the blades (7) of a wind driven generator (9) to rotate around a rotation shaft (8) of the wind driven generator to drive the wind driven generator (9) to generate the direct current; the direct current is input into a wind power inverter (1) to be converted as the alternating current after inputting into a wind power controller (10) by a lead wire (4); the alternating current converts the electric energy as the heat energy after inputting into a wind power temperature heating device (16); it radiates the heat energy, properly increases the temperature of the fermentation liquid, promotes the growth and breeding of the methane bacteria, and accelerates the decomposition speed of the organic to increase the yield of the methane in the same time; the methane raw material is introduced into the fermentation chamber (17) of the methane tank (19) from a material feeding chamber (13) by a feeding tube (14); the fermentation liquid in a water pressing chamber (21) presses the outlet of a discharge tube (20) to make the fermentation chamber (17) of the methane tank (19) form an anaerobic environment, thus the methane bacteria in the methane fermentation bacteria group can normally generate the methane; the methane generated in the fermentation chamber of the methane tank (19) is raised into an gas storing chamber (18) to form a certain pressure after accumulating the methane; when the user uses the methane, the methane is output by an gas output pipe (22) and an air storing cover (23) to burn the methane furnace of the user; and when a movable cover (12) on the top of the methane tank (19) is moved away, the maintainer goes into or comes out of the methane tank; or the cleaner goes into or comes out of the methane tank to clean the methane slag.
