Industrial flue gas desulfurizing, denitration and dedusting system

Abstract

The invention belongs to the technical field of industrial waste gas treatment and specifically relates to an industrial flue gas desulfurizing, denitration and dedusting system which comprises a dedusting cavity, a driving gear, a swinging supporting plate, a driven gear, a rack and a spiral vibration part, wherein a sector-shaped gear is arranged at one end of the swinging supporting plate witha rotating shaft as the circle center, the sector-shaped gear and the driving gear are meshed with each other, a swinging arm is arranged at one end of the swinging supporting plate, the driven gear is arranged on an end head of the swinging arm in a rotating mode, the rack is arranged under the driven gear, the rack is arranged at the bottom end of the swinging supporting plate in a sliding mode,and the bottom surface of the rack is fixedly connected with one end of one set of the spiral vibration part. According to the industrial flue gas desulfurizing, denitration and dedusting system disclosed by the invention, a fixing nut is arranged in the middle of the sliding rod, the sliding rod can drive the fixing nut to rotate through a ball screw nut pair, the fixing nut can drive a gear setto rotate, the gear set can drive the spiral vibration part to rotate, and ash stopping cloth at an outer ring of the spiral vibration part can intercept and vibrate down large particles in flue gasin the dedusting cavity.

Description

technical field [0001] The invention belongs to the technical field of industrial waste gas treatment, in particular to an industrial flue gas desulfurization, denitrification and dust removal system. Background technique [0002] Coal is the main energy source in our country, and the problems of sulfur dioxide and acid rain pollution associated with it will become more prominent. Sulfur, chlorine, and nitrogen oxides produced by coal combustion are the main sources of air pollution. In addition to destroying the ecological environment, they can also form photochemical smog, which is harmful to human health. A large number of catalysts are used in the desulfurization and denitrification reaction, and it is particularly important to maintain high activity of the catalyst and economical operation; but the catalyst works in a high-dust environment, which may easily lead to dust accumulation and blockage of the catalyst; at the same time, due to the Contains many large particle...

AI Technical Summary

Problems solved by technology

This technical solution can realize dust removal before the desulfurization and denitrification reaction; but the spiral dust collector in this solution is difficult to remove large particles in the flue gas, which affects the pretreatment effect before desulfurization and denitrification
