A dust removal device and dust removal method for dust-containing and tar-containing gas

Abstract

A dust removal device and dust removal method for gas containing dust and tar, relating to a dust removal device, the dust removal device includes at least two dust removal units, and each dust removal unit includes a housing, an air inlet branch pipe, a storage dust bin and a dust removal unit. The filter device is equipped with a storage dust bin on one side of the shell, an air inlet cavity is arranged on the upper part of the dust storage bin, and a filter device is installed on the outer middle part of the dust storage bin. The filter devices include a flat rod control rod, a flat Material rod, discharge rod, filter bed and baffle plate, the outer middle part of the storage dust bin are equipped with a filter bed, the filter surface of the filter bed is covered with filter material, and the lower part of the filter bed is equipped with a clean air chamber. A discharge rod assembly with a connecting rod structure is installed in the room, and a baffle plate connected with the discharge rod assembly is provided on the inside of the filter bed; the present invention effectively solves the problem that the filter material is bound by tar and loses the filtering effect, without affecting the device and Production of the process.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device and a dust removal method for gas containing dust and tar. Background technique [0002] It is known that the dust removal methods applied to dusty and tar-containing gas are mainly electric dust removal and filter dust removal. Electric dust removal is used for dust removal of tar-containing gas, which has poor corona stability, electrode corrosion, specific resistance to dust and gas composition. The nature is sensitive to uncertainty, and it has not been used stably in the field of dust removal of high-temperature tar-containing gas. Filtration dust removal has high dust removal efficiency, such as particle bed dust collector, ceramic filter tube dust collector and metal film filter tube dust collector, etc. Changes have a greater impact. Once the gas temperature fluctuates, tar will precipitate, and the precipitated tar will stick to particles or block the filte...

AI Technical Summary

Problems solved by technology

However, when the dust collector is used for dust removal of tar-containing gas, there will be problems. When the tar-containing gas passes through the dust collector, the temperature will drop, resulting in the precipitation of tar. The precipitated tar will stick to the particles, causing the operation effect of the particle bed to drop greatly, and even stop production; Therefore, it is a basic demand of those skilled in the art to propose a dust-containing and tar-containing gas dedusting device that realizes the back-blowing regeneration of the filter material and can also perform online filter material replacement when the filter material is bonded.
