Embedded type electric bag compound dust remover

Abstract

The invention discloses an embedded type electric bag compound dust remover comprising a front-stage electric field dust-removing region and an embedded type electric bag compound dust removing region, which are sequentially arranged in a shell from front to back, wherein in the embedded type electric bag compound dust removing region, two sides of each piece of a back-stage corona electrode framework are provided with a dust-collecting pore plate or a rows of the dust-collecting pore plates; spaces between the two dust-collecting pore plates or the two rows of the dust-collecting pore plates are back-stage electric field channels; at least one filtering bag set comprising a row of filtering bags is arranged between any two adjacent back-stage electric field channels; and vent holes on the dust-collecting pore plates are air flow channels for smoke in the back-stage electric field channels to enter the filtering bag set. The height of the dust-collecting pore plates and the height of the corona electrode frameworks are commonly about 4 meters higher than the length of the filtering bags of the filtering bag set, so that a lot of dust, including falling dust when the dust in the filtering bags is removed, can be captured below the filtering bag set; and with adoption of a longer filtering bag dust removing period, the dust-removing efficiency of the dust remover can be further improved and the service life of the filtering bags can be prolonged.

Description

technical field [0001] The invention relates to the field of industrial dust removal, in particular to an embedded electric bag composite dust collector. Background technique [0002] In industries such as thermal power generation, building material production and metallurgy, industrial dust collectors are widely used to capture dust in flue gas to reduce the concentration of PM2.5 in the atmosphere, thereby improving the quality of the atmospheric environment and protecting human health. At present, the electric bag composite dust collector is a commonly used industrial dust collector. In the 1990s, the Energy and Environmental Research Center (EERC) of the University of North Dakota in the United States developed the embedded electric bag composite dust removal technology to prevent most of the secondary dust generated by any row of filter bags from being swept away by the adjacent row of filter bags. or adsorb itself again. The US patent application number is 09 / 813,497...

AI Technical Summary

Problems solved by technology

In this large space, neither the corona pole nor the dust collection pole is installed, so that the dust concentration of the flue gas at the entrance of the filter bag dust removal area is significantly higher than that when the corona pole and the dust collection pole are installed, so it is necessary to install A relati
