Dust treatment system for dusting workshop

Abstract

The invention discloses a dust treatment system for a dusting workshop. The dust treatment system for the dusting workshop comprises a dust collecting device, a horizontal filter drum type dust collector and a smoke exhausting device which are sequentially arranged in a dust flow direction, and an induced draft fan is further arranged on a dust flow channel; the dust collecting device communicateswith the horizontal filter drum type dust collector, and the horizontal filter drum type dust collector communicates with the smoke exhausting device; the horizontal filter drum type dust collector is provided with at least one dust treatment bin, each dust treatment bin comprises a first support, a bin body, an exhaust gas inlet, a clean air outlet and a dust collecting hopper. The dust treatment system for the dusting workshop, disclosed by the invention, is adopted to perform centralized treatment on dust in the workshop, so that the dust with large particle size is prevented from enteringa filter cylinder, dust airflow flowing into the equipment can be uniform, the flow velocity of the dust airflow on the outer wall of the filter cylinder is decreased, the filter effect of the filtercylinder is improved, the cleanliness of discharged gas is enhanced, the dust concentration in the gas is less than or equal to 30mg/m3, noise can be reduced to 30 to 40dB, the effects of sound elimination and noise reduction are ideal, national emission standards are met, and the standards of the dust treatment system for the dusting workshop are higher than the national emission standards.

Description

technical field [0001] The invention belongs to the technical field of dust collection equipment, in particular to a dust collection equipment used for industrial dust treatment. Background technique [0002] With the rapid development of industry, all kinds of dust will be produced in the process of industrial production. The emission of this kind of industrial dust will destroy the air environment of the workshop, and then endanger the health of the operators and damage the machinery and equipment of the workshop. If it is discharged randomly, it will also pollute the air environment. Cause social public nuisance, so the proper treatment of industrial dust is conducive to improving the operating air environment of the workshop and preventing air pollution. [0003] The current treatment method is mainly to discharge the industrial dust after being treated by the dust collector, but the internal structure design of the air inlet of the existing dust collector is unreasonabl...

AI Technical Summary

Problems solved by technology

[0003] The current treatment method is mainly to discharge the industrial dust after being treated by the dust collector, but the internal structure design of the air inlet of the existing dust collector is unreasonable, and the dust cannot evenly flow to each filter cartridge after entering the dust collector from the air inlet. When the airflow passes through the filter cartridge, it is easy to damage the structure of the filter cartridge, and the dust with large particle size will be directly embedded in the filter material of the filter cartridge, which will also damage the structure of the filter cartridge, which will reduce the service life of the filter cartridge

[0004] For example, the Chinese patent "Dust Waste Gas Treatment Device", application publication number: CN 104258664 A, discloses a kind of dust treatment equipment. At present, most of the treatment methods for this kind of dust waste gas use a segmented and multi-stage joint treatment process to treat the flue gas. The dust and waste gas produced by polluting enterprises are treated in an environmentally friendly manner, that is, the treatment of waste gas and dust is generally carried out in different treatment systems. Increased ground area, inconvenient operation and management, large equipment investment cost, long treatment process, high treatment cost, in addition, in the existing dust treatment process, due to the limitation of equipment structure and treatment effect, it is difficult to reach 100mg / m 3 emission standards

[0005] In addition, the noise of the gas emitted by this type of equipment is very loud, which cannot meet the national emission standard "GB22337-2008 Noise Emission Standard for Social Life"
