A biogas desulfurization device comprises an anaerobic system, a desulfurization liquid circulating system, an oxygen supply device and a desulfurization system, wherein the anaerobic system is used for generating biogas and filling the generated biogas into the desulfurization system, the desulfurization liquid circulating system is used for filling the desulfurization liquid into the desulfurization system and recycling the desulfurization liquid that has undergone the desulfurization operation, the oxygen supply device is used for filling air into the desulfurization system, and the desulfurization system which comprises at least one stage desulfurization tower group is used for carrying out the desulfurization operation on the biogas from the anaerobic system, the desulfurization operation is conducted by the desulfurization liquid received from the desulfurization liquid circulating system in an aerobic environment. The biogas desulfurization device can reduce the amount of hydrogen sulfide in the biogas to less than 10 ppm while eliminating secondary pollution.

Biogas desulfurization device

The present invention relates to a grit chamber, wherein the chamber body of the grit chamber is in the shape of a hollow cylinder with a cone-shaped bottom; a grit channel is installed below the center of the cone-shaped bottom; a grit removing device is installed in the grit channel; a wall mixer, a plurality of vertical mixers and a spiral grit remover are installed in the chamber body; the wall mixer is installed on the wall of the hollow cylinder; the spiral grit remover is installed in the center of the cylinder, and is provided with a grit-removing blade for removing the grit on the cone-shaped bottom; and the vertical mixers are installed at the position close to the cone-shaped bottom and are vertical to the wall. The invention also provides a grit removing system containing a grit chamber and a grit removing method. With the vertical mixers and the wall mixer, the grit removing device is capable of efficiently and completely sinking the grit in the dung of domestic animals into water bottom so as to completely separate the grit from the dung of domestic animals. In the process of material transportation, the feathers contained in the dung of domestic animals pass through a cutting and filtering device so that the feathers become fermentation material.
