A waste gas treatment device

Abstract

A novel exhaust-gas treatment apparatus is applied to treat exhaust gas of processing equipment (200) possessing multiple internal work stations (201), wherein the processing equipment (200) comprises six internal work stations (201) uniformly distributed at the circumferential direction; each internal work station (201) is communicated with an exhaust-gas treatment device (100) at the central of the processing equipment (200) via connection pipes (202), and thus processing exhaust gases generated in the internal work stations (201) are sent to the exhaust-gas treatment device (100) for filtering; and the exhaust-gas treatment device (100) comprises a support frame, six exhaust-gas filtering column units arranged on the support frame, and bottom annular plates (300) which is arranged at the bottom of the support frame and is provided with exhaust-gas inlet pipelines (71) used for connecting the exhaust-gas filtering column units with the responding connection pipes.

Description

technical field [0001] The present application relates to the field of exhaust gas treatment, in particular to an exhaust gas treatment device. Background technique [0002] In some processing equipment with multiple internal workstations, such as grinding processing equipment, it is often necessary to treat the exhaust gas with particles generated by the processing. In the exhaust gas treatment device, a plurality of adjacent filter tubes are often arranged to simultaneously filter the exhaust gas so as to increase the filtering area. However, in the long-term use process, due to the small distance between the adjacent connected sides of the rows of filter tubes, the conditions of exhaust gas filtration and adsorption are different from those of the open front and rear sides, which makes the filter tubes have different adsorption effects in the circumferential direction. distribution zone.

However, in the long-term use process, due to the small distance between the adjacent connected sides of the rows of filter tubes, the conditions of exhaust gas filtration and adsorption are different from those of the open front and rear sides, which makes the filter tubes have different adsorption effects in the circumferential direction. distribution zone

At the same time, due to long-term work, this filter material has reached its service life due to the adsorption of a large amount of dirt, and the replacement of the filter material is complicated. In most cases, the entire filter device will be discarded and updated after the filter material life expires. device
