NOVELTY - Solar plant device comprises solar energy is installed in house of straw pre-processing pool (1) and ferment tank (5), waste collecting device, fermentation tank is cylindrical horizontal seal tank body, one end of producer hole (5-2), where lower part of tank body with the tank drainage device (5-3), a tank body through the tank body support leg (5-1) is set with upper part in the solar house, where straw pre-treatment tank is composed of tank body (1-1) and tank cover (1-3) is composed of two parts of straw pre-processing pool is set water inlet valve (1-2) and feeding hopper (1-4).    USE - As solar plant for gasifying straw and waste residue (claimed).    ADVANTAGE - The fermentation tank provided with propeller pusher to push the material uniformly filled with fermentation tank, the fermentation tank is provided with more than one agitator II, of the tank material uniformly stirring, gasification effect is good, the yield is high.    DETAILED DESCRIPTION - Solar plant device comprises a solar energy is installed in the house of straw pre-processing pool (1) and ferment tank (5), further comprising a solar energy house outside of the air storage tank (18) and waste collecting device, where the fermentation tank is a cylindrical horizontal seal tank body, one end of the producer hole (5-2), the lower part of the tank body with the tank drainage device (5-3), a tank body through the tank body support leg (5-1) is set with the upper part in the solar house, where the straw pre-treatment tank is composed of tank body (1-1) and tank cover (1-3) is composed of two parts of the straw pre-processing pool is set water inlet valve (1-2) and the feeding hopper (1-4), the pre-processing in the straw pre-processing pool through a feeding pipe (3-1) into the fermentation tank, fermentation tank (marsh gas generated in step through a gas pipe (8) enters the air storage tank (18), where the storage tank in the marsh gas to the air after the straw gas device, the fermentation tank into organic fertilizer of marsh (12) and marsh gas-liquid through gas pipeline (13), the marsh and biogas liquid through the conveying pipe (10) enters the waste collecting device, where the straw pre-treatment tank is installed on the fermentation tank one end of the straw pre-processing pool of the embedded solar energy temperature, straw preprocessing pool is provided with a feeding pump (3), the feeding pump pre-processing the material through a feeding pipe into the fermentation tank, the upper part of the fermentation tank is set outlet, the feeder is type propeller; discharging machine of the marsh and biogas liquid through the conveying pipe enter into fertilizer collecting device, the collecting device is fertilizer separating cup for separating residue from water tank structure (11), a slag water separating tank is composed of a separating tank body (11-1) and a filter net (11-2) is composed of two parts, the filter screen is horizontally fixed in the separating tank body, and a marsh discharging machine of the filter screen.
