Gas supply device for preventing and controlling coal combustion pollution

Abstract

The invention discloses a gas supply device for preventing and controlling coal combustion pollution and relates to the technical field of pollution prevention, a plurality of air holes are uniformly formed in the inner bottom wall of a placement groove, a rotating ring is rotatably connected to the inner wall of the placement groove, a knob is fixedly connected to the inner wall of the rotating ring, and a plurality of rotating frames are uniformly and fixedly connected to the outer end of the rotating ring and located in the placement groove in a surrounding manner; reserved movable channels are formed in the left side and the right side of the inner wall of an air supply pipeline, and a plurality of integrated openings are formed in the inner walls of the reserved movable channels; the smoke dust removal and purification work is performed in a targeted manner, the purification effect is improved under the conditions that water is released in a large range and water sources are saved, and the defects that civil bulk coal emission belongs to non-point source pollution, the amount is large, the range is wide, and the environmental influence is large are overcome, and the problems that the diffusion range of harmful gas is large in the discharging process, air is affected, and after the harmful gas inhales the gas discharged by coal combustion, discomfort is prone to occurring, and harm is large are solved.

Description

technical field [0001] The invention relates to the technical field of pollution prevention and control, in particular to an air supply device for coal combustion pollution prevention and control. Background technique [0002] Coal is a solid combustible mineral gradually formed by ancient plants buried in the ground through complex biochemical and physical chemical changes. It is a solid combustible organic rock, mainly produced by the biochemical action of plant remains. Air pollution, it produces many harmful gases, mainly including: sulfur dioxide, hydrogen sulfide, nitrogen monoxide, etc., among which sulfur dioxide is the most, and dust, SO2 pollution in the atmosphere is mainly caused by the combustion of fuels including coal ; [0003] Existing civilian scattered coal discharge belongs to non-point source pollution, which has the disadvantages of large volume and wide area and great environmental impact. The harmful gas diffuses in a large range during the discharge...
