Exhaust gas treatment unit for processing plants with multiple internal workstations

Abstract

The invention provides a waste gas treatment device (100) for treating waste gas of processing equipment (200) provided with a plurality of internal work stations (201). The processing equipment (200) comprises the six internal work stations (201) which are evenly arranged in the circumferential direction. Each internal work station (201) is communicated with the waste gas treatment device (100) located at the center of the processing equipment (200) through a connecting pipe (202), so that processing waste gas produced in each internal work station (201) is conveyed into the waste gas treatment device (100) and filtered. The waste gas treatment device (100) comprises a supporting frame, six waste gas filtering column units arranged in the supporting frame and an annular bottom plate (300), wherein the annular bottom plate (300) is arranged at the bottom of the supporting frame and provided with waste gas inlet pipelines (71), and the waste gas inlet pipelines (71) are used for connecting the waste gas filtering column units with the corresponding connecting pipes (202).

Description

technical field [0001] The present application relates to the field of exhaust gas treatment, in particular to an exhaust gas treatment device for treating exhaust gas of processing equipment with multiple internal working stations. 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 z...

Problems solved by technology

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
