Embodiment Construction
[0012] figure 1 , figure 2 and image 3As shown, the biogas generator and the coal straw gasification device. The biogas generating device is mainly composed of biogas digester 1, rotary biogas generator, front partition wall 2, screw pumping machine 11, rear partition wall 3, motor 6, driving bevel gear 7, driven bevel gear 8, and screw feeder 9. It is composed of a sealing clip 10, a mud pump 12 or a screw mud pump, a centrifugal dryer 13 and a heating pipe 14. The bottom of the biogas digester 1 is high at the front and low at the rear and slopes downward, and the biogas digester 1 is made of heat-insulating sealing material. The rotary biogas generator is mounted on the front partition wall 2 and the rear partition wall 3 with a high front and a low rear. There is a rotary frame inside the rotary biogas generator. The rotary frame is composed of circular steel bars and horizontal steel bars, and ribs are installed on the horizontal steel bars. The rotary frame of the...

The invention discloses a biogas generating device, a coal straw gasification device and a control method. The biogas generating device is mainly composed of a biogas digester, a rotary biogas generator, a front partition wall, a propeller pump, a rear partition wall, an electric motor, a driving bevel gear, a driven bevel gear, a screw feeder, a seal clamp, a mud pump or It consists of a screw mud extractor, a centrifugal dryer and a heating tube. The structure of the coal straw gasification device is as follows: from the outside to the inside of the furnace body, there are outer shell, rotary kiln, interlayer rotary net and inner rotary net. Coal is sent to the interlayer between the rotary kiln and the interlayer rotary net. The straw is sent to the interlayer between the interlayer rotary net and the inner rotary net. The biogas burner ignites the straw, and the straw burns to ignite the pulverized coal. The rotary kiln rotates, and the water vapor reacts with the high-temperature coal in the rotary kiln to produce gas. The high-temperature gas-fired boiler produces water vapor, which then heats the combustion-supporting air and the water in the biogas digester. After gas desulfurization becomes clean gas. The biogas generator can produce biogas in any season.
Description
Technical field: [0001] The invention relates to a biogas generating device, a coal straw gasification device and a control method. Background technique: [0002] The waste left by rural agricultural production——crop straw is the raw material for biogas production. The straw is mixed with water and fermented, and the bacteria decompose and decompose the straw at a temperature of 33°C to produce biogas with a methane content of 70%. When the minimum temperature is above 10°C, the straw is soaked in water to ferment to produce heat so that the straw hydrate is kept above 33°C, and the bacteria decompose and decompose the straw at a temperature of 33°C to produce biogas. The lowest temperature is above 10°C, and only Hainan Province can reach this temperature standard throughout the year, while Heilongjiang Province in the northeast cannot reach this temperature standard throughout the year. After the straw is mixed with water, the straw will float on the water surface, and t...
