Self-shaking falling-off cleaning type filtering device for waste gas and dust treatment

Abstract

The invention discloses a self-shaking falling-off cleaning type filtering device for waste gas and dust treatment, and belongs to the technical field of waste gas and dust treatment.The self-shakingfalling-off cleaning type filtering device is provided with a pressed pushing body which moves downwards in a pressed mode along with high air pressure, and when a filtering net reaches certain adsorption saturation, a magnetic shielding body is pulled to move downwards and disengage from a magnetic ball; and the magnetic shielding effect on the magnetic ball is weakened to a certain extent, at the moment, the magnetic shielding body repels a magnetic repulsion body, the magnetic repulsion body and the filter net expand outwards together, filter holes of the filter net are enlarged, a small amount of dust is shaken off in the expanding process, the filter net has the refiltering capacity, and the air pressure in the filter net is gradually reduced. The magnetic shielding body is reset upwards under the stretching action of the elastic stretching rope to magnetically shield the magnetic repulsion body, the filter net is reset inwards under the elastic action of a compression spring, dust is shaken in the reset rebounding process, meanwhile, a piston type water pressing mechanism is extruded to spray water when the filter net moves inwards, and the flocculation and dust falling effects on the dust are achieved. Agglomerated dust falls into a dust receiving barrel to be collected.

Description

technical field [0001] The invention relates to the technical field of textile dust treatment, and more specifically relates to a self-shaking and shedding cleaning filter device for waste gas dust treatment. Background technique [0002] At present, with the improvement of the requirements for the treatment of factory waste gas, the waste gas dedusting device has gradually become an indispensable part of the process of factory waste gas treatment. Industrial waste gas contains a large amount of dust. If it is not treated and discharged directly into the air, it will cause environmental damage. Pollution, industrial waste gas containing harmful gases, if the dust removal treatment is not carried out first, it will also cause damage to the reaction device for subsequent processing, and the dust can only be discharged after passing through the reaction device.

[0002] At present, with the improvement of the requirements for the treatment of factory waste gas, the waste gas dedusting device has gradually become an indispensable part of the process of factory waste gas treatment. Industrial waste gas contains a large amount of dust. If it is not treated and discharged directly into the air, it will cause environmental damage. Pollution, industrial waste gas containing harmful gases, if the dust removal treatment is not performed first, it will also cause damage to the reaction device for subsequent processing, and the dust can only be discharged after passing through the reaction device

[0003] Although many enterprises use the dust removal device to process the waste gas before discharging it, but the dust will adhere to the inside of the dust removal device (filter), which will affect the treatment effect and the service life of the device; at the same time, the dust removal device will reach a certain degree of saturation in the adsorption Finally, it is necessary to clean and maintain the device to ensure the subsequent filtration work, which increases the burden on the staff to a certain extent and hinders the work efficiency; The loss will increase significantly, and the dust removal efficiency will also decrease
