Waste gas multi-filtering equipment

Abstract

The invention relates to the technical field of environmental protection equipment, in particular to waste gas multi-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; 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, when the air pressure of each filtering space is too large, the pressure of each air filtering space can be relieved through automatic deformation of the filtering disc, and the waste gas filtering efficiency and normal operation of the whole equipment are guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a multiple filtering equipment for waste gas. 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, seriously affecting human health and greatly affecting 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 tr...

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
