Treatment device for dust and waste gas in building material industry

Abstract

The invention discloses a treatment device for dust and waste gas in the building material industry. The treatment device comprises a box body, a particle filtering mechanism, an air duct adjusting mechanism, a cloth bag dust removal mechanism, a speed reduction mechanism and an acid-alkali washing mechanism; the particle filtering mechanism, the air duct adjusting mechanism, the cloth bag dust removal mechanism, the speed reduction mechanism and the acid-alkali washing mechanism are arranged in the box body; the particle filtering mechanism is arranged at one end of the box; the acid-alkali washing mechanism is arranged at the other end of the box body; the speed reducing mechanism is positioned between the particle filtering mechanism and the cloth bag dust removing mechanism; the cloth bag dust removal mechanism is positioned between the speed reduction mechanism and the acid-alkali washing mechanism; and the particle filtering mechanism comprises a filtering plate, a control plate, a buffering mechanism, a material guiding mechanism, a material guiding plate and a discharging mechanism. Large particles can be independently filtered, and the damage rate of a cloth bag in cloth bag dust removal is reduced; meanwhile, in the cloth bag dust removal mechanism, sticking substances attached to the surfaces of the cloth bags can be loosened through vibration, so that the cleaning effect of back flushing of the cloth bags is improved.

Description

technical field [0001] The invention belongs to the technical field of industrial waste gas treatment, in particular to a treatment device for dust waste gas in the building material industry. Background technique [0002] In the building materials industry, especially in brick factories, dust waste gas containing large particles is often produced; 1) The existing dust waste gas treatment devices mostly use multi-layer filtration for adsorption treatment, without separate treatment of large particles, so during the treatment process Medium and large particles tend to be on the adsorption layer, reducing its service life; 2) Usually, bag dust removal is used, but when the weather is humid or rainy, there is more moisture in the air; dust will appear on the surface of the bag under long-term working conditions Bonding, and difficult to handle, greatly reducing the effect of back-blowing cleaning bags; 3) need to sinter bricks will produce sulfide impact on the environment, nee...

Problems solved by technology

[0002] In the building materials industry, especially in brick factories, dust waste gas containing large particles is often produced; 1) The existing dust waste gas treatment devices mostly use multi-layer filtration for adsorption treatment, without separate treatment of large particles, so large particles tend to be on the adsorption layer during the treatment process, reducing its service life; There is a lot of moisture inside; dust sticks will appear on the surface of the bag under long-term working conditions, and it is not easy to handle, which greatly reduces the effect of backflushing to clean the bag; 3) The need for sintering to make bricks will produce sulfides that will affect the environment and require desulfurization treatment
