Problems solved by technology
At present, there are two main ways to connect the electrostatic precipitator area and the bag precipitator area in the electrostatic bag precipitator. One is direct connection. If the filter bag is large, it will cause serious wear and tear on the filter bag. Secondly, it will also cause uneven airflow distribution in the bag dust removal area, and the load on the front filter bag will be relatively large. The backflow enters the electrostatic precipitator area, affecting the dust removal efficiency of the electrostatic precipitator area

Embodiment Construction
[0022] Such as figure 1 As shown, the electric bag dust collector of the present invention includes an electric dust removal area 11, a bag dust removal area 12 and a flow guide device 13, and the flow guide device 13 is installed between the electric dust removal area 11 and the bag dust removal area 12 Between, and the guide device 13 is provided with a plurality of airflow passages 20 communicating with the electrostatic precipitator area 11 and the bag dust removal area 12 . After passing through the electrostatic precipitator area 11 for dust removal, the flue gas passes through the plurality of airflow passages 20 of the flow guiding device 13 and enters the bag dust removal area 12 for dust removal. Wherein, the bag dust removal area 12 is provided with multiple rows of filter bags, and the arrangement of the multiple rows of filter bags belongs to the prior art, and the present invention will not repeat them here.

The invention discloses an electric bag dust collector comprising an electric dust collection region, a bag dust collection region and a flow guide device, wherein the flow guide device comprises a shell and a plurality of flow guide plates; a plurality of the flow guide plates are fixedly arranged in the shell from top to bottom to form a plurality of air flow channels; in the two adjacent flow guide plates, the tail end of the flow guide plate at the upper part and the head end of the flow guide plate at the lower part are located on the same horizontal plane; and the tail end of the flow guide plate at the bottom part and the bottom face of a filtering bag located at the most front row are located on the same horizontal plane. The flow guide device is arranged between the electric dust collection region and the bag dust collection region to reduce the brushing on the filtering bag on the front row of the bag dust collection region by an air flow, so that the air flow in the bag dust collection region is distributed uniformly, and the load of the filtering bag of the front row is reduced. Furthermore, the resistance between the electric dust collection region and the bag dust collection region is reduced and the air flow is prevented from being reflowed back to the electric dust collection region to influence the dust collection efficiency of the electric dust collection region.
Description
technical field [0001] The invention relates to the technical field of dust removal, in particular to an electric bag dust collector. Background technique [0002] Electrostatic bag filter is a new type of dust removal device, which combines the advantages of electrostatic precipitator and bag filter, and has the characteristics of reliability, small footprint, low investment and maintenance costs, and high dust removal efficiency. At present, there are mainly two ways to connect the electrostatic precipitator area and the bag precipitator area in the electrostatic bag precipitator. One is direct connection, the airflow passes through the electrolytic precipitator area and directly enters the bag precipitator area, and the filter bags in the front row of the bag precipitator area are less washed out. The filter bag is too large, which causes serious wear of the filter bag. Secondly, it also causes the airflow distribution in the bag dust removal area to be uneven, and the l...
