Waste gas filtering equipment

Abstract

The invention relates to the technical field of environmental protection equipment, in particular to waste gas filtering equipment which comprises a waste gas treatment bin, a gas inlet end and a gas outlet end. A multi-filtering mechanism is arranged in the waste gas treatment bin and is provided with a rotating shaft extending from the gas inlet end to the gas outlet end and filtering discs mounted on the rotating shaft; an ultrasonic cleaning mechanism for cleaning the filtering discs is arranged in the lower space in the waste gas treatment bin; a partition plate is horizontally arranged in the middle of the inner side of the waste gas treatment bin, divides the inner space of the waste gas treatment bin into an upper bin body and a lower bin body, and is provided with a through hole for the filtering discs to penetrate through; and the internal space of the upper bin body is divided into a plurality of independent filtering spaces by the filtering discs. Large-particle impurities and colloidal substances in waste gas can be efficiently filtered out, the filter screen holes can be self-cleaned, the waste gas backflow function is achieved, the filtering effect is improved on the whole, the mesh holes are prevented from being blocked, and the waste gas is prevented from being introduced to the outside to affect the working environment.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to waste gas filtering equipment. Background technique [0002] Waste gas pollution control is one of the main areas of environmental protection. Volatile organic pollutants (VOCS) are one of the main pollution factors that produce smog, which seriously affects human health and greatly affects people's quality of life. At present, the pollution of VOCS to the environment has been widely concerned. [0003] Whether it is coal-fired flue gas desulfurization, denitrification and mercury removal, waste incineration, cement burning, waste gas generated in various industrial kilns and industrial production, combustion of biomass fuel, solid particles in various waste gases containing VOCS, Dirt such as aerosol, oil, paint residue and salt will cause serious pollution to environmental protection equipment and corresponding catalysts for waste gas treatment, thus...

Problems solved by technology

[0003] Whether it is coal-fired flue gas desulfurization, denitrification and mercury removal, waste incineration, cement burning, waste gas generated in various industrial kilns and industrial production, combustion of biomass fuel, solid particles in various waste gases containing VOCS, Dirt such as aerosol, oil, paint residue and salt will cause serious pollution to the environmental protection equipment and corresponding catalysts for waste gas treatment, thus affecting the treatment efficiency of environmental protection equipment

[0004] In order to solve this problem, the exhaust gas must be pretreated. When the existing technology filters the exhaust gas, the sealing of the equipment itself is not strong, which is easy to cause exhaust gas leakage, pollute the working environment, and affect the health of the staff. In the prior art, the filter Most of them use the method of filtering all large particles of pollutants at one time, which is very easy to block the leaks, affecting the filtering effect and service life of the equipment, and the existing technology needs to stop maintenance when cleaning the filter screen, which reduces the efficiency of waste gas treatment
