An embedded electric bag composite dust collector with a composite dust collecting orifice

Abstract

The invention discloses an embedded type electrostatic-fabric integrated dust collector with composite type dust collecting pore plates, and belongs to the field of atmospheric pollution treatment. The electrostatic-fabric integrated dust collector can overcome technical problems of embedded type electrostatic-fabric integrated dust collectors at present, such as much reentrainment of dust, dust collection efficiency reduction and service lifetime shortening of filter bags. The electrostatic-fabric integrated dust collector comprises front-stage corona electrodes and front-stage dust collection electrodes in a front-stage electric field dust collecting zone, and comprises back-stage corona electrode frames, the composite type dust collecting pore plates and filter bag groups in an embedded electrostatic-fabric integrated dust collecting zone. Each of the composite type dust collecting pore plates comprises a dust collecting pore plate and more than two assistant dust collecting plates connected to the corresponding dust collecting pore plate. Each of the assistant dust collecting plates is opposite to one row or two rows or a plurality of rows of vent pores in the corresponding dust collecting pore plate. When the composite type dust collecting pore plates are subjected to dust cleaning, only a small part of flake dust and agglomerate dust can touch edges of the assistant dust collecting plates during dropping processes, thus largely reducing reentrainment of dust.

Description

technical field [0001] The invention relates to the field of industrial dust removal, in particular to an embedded electric bag composite dust collector with a composite dust collection orifice. Background technique [0002] With the development of economy and society, the country pays more and more attention to environmental protection, PM2.5, SO 3 It is urgent to control the emission of acid mist, mercury and other pollutants in the form of aerosols. The "Ambient Air Quality Standards" (GB3095-2012) jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China has added PM2.5 monitoring indicators. Moreover, the Ministry of Environmental Protection requires that in 2012, key regions such as the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta, as well as municipalities directly under the Central Government and provincial capitals,...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to appropriately shorten the dust cleaning cycle of the filter bag, resulting in a decrease in the dust removal efficiency of the enhanced coupling type embedded electric bag composite dust collector and a shortened service life of the filter bag.
