Description

Technical Field

[0001] The utility model relates to the technical field of flue gas dust removal equipment, and particularly relates to a high-efficiency electric bag composite dust collector. Background Art

[0002] An electric bag composite dust collector is a high-efficiency dust collector that organically integrates two dust removal mechanisms of electrostatic dust removal and filtration dust removal. Through the pre-dust collection and charging effects of the front-stage electric field and the filtration dust removal in the rear-stage filter bag area; the existing electric bag composite dust collector, as shown in the utility model with the application number 201621348406.X, includes an electrostatic dust removal area and a bag filter dust removal area arranged in sequence. However, with this structural arrangement method, when the flue gas passes through the bag dust removal area after passing through the electrostatic dust removal area, there is uneven flue gas distribution, which may cause greater damage to the filter bags near the electrostatic dust removal area. At the same time, it also directly affects the dust removal effect of the flue gas in the bag dust removal area. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies in the above background art and provide an electric bag composite dust collector that can ensure relatively uniform distribution of flue gas passing through the filter bags to guarantee the overall dust removal effect.

[0004] To achieve the above purpose, a high-efficiency electric bag composite dust collector of the utility model adopts the following technical solutions:

[0005] A high-efficiency electric bag composite dust collector includes a housing. An electrostatic dust removal area and a bag dust removal area are arranged left and right inside the housing. Ash hoppers are evenly arranged below the electrostatic dust removal area and the bag dust removal area. An inlet pipe is provided on the left side of the housing, and an outlet pipe is provided on the upper right side of the housing. A flow guiding structure is arranged between the electrostatic dust removal area and the bag dust removal area. The flow guiding structure includes a first flow guiding plate arranged vertically. A second flow guiding plate that is inclined downward towards the side of the bag structure in the bag dust removal area is arranged below the first flow guiding plate. A third flow guiding plate is also arranged below the filter bags in the bag dust removal area. The third flow guiding plate includes a ventilation plate. The ventilation plate is provided with a fan-shaped notch and a number of ventilation holes. An extension plate extends downward from the outer periphery of the third flow guiding plate towards the side away from the third flow guiding plate. The third flow guiding plate is rotatably connected to the bag dust removal area.

[0006] A further improvement of the high-efficiency electric bag composite dust collector of the utility model is that the first flow guiding plate is arc-shaped, and both ends extend into the bag dust removal area.

[0007] A further improvement of the high-efficiency electric bag composite dust collector of the utility model is that the third flow guiding plate is inclined downward from the center to the edge.

[0008] A further improvement of the high-efficiency electric bag composite dust collector of the present utility model lies in that a connecting rod is provided upward at the center of the third deflector plate. The connecting rod is connected to the flower plate arranged in the bag dust removal area through a bearing. An auxiliary housing is provided on the right side of the outer housing, and a driving motor is provided above the auxiliary housing. The output shaft of the driving motor extends into the auxiliary housing and is connected to the connecting rod or the extension plate through a transmission structure.

[0009] A further improvement of the high-efficiency electric bag composite dust collector of the present utility model lies in that an auxiliary blowing structure is further provided in the auxiliary housing, and the blowing pipe of the auxiliary blowing structure faces the third deflector plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model realizes relatively uniform passage of flue gas through the filter bags by arranging the deflector plates, ensuring the effect of bag dust removal. At the same time, it also avoids the damage of a single filter bag during long-term operation, and further avoids the impact on the overall working efficiency caused by the disassembly and replacement of a single filter bag. On the other hand, the design of the deflector plates can also block some dust in the flue gas, which is beneficial to improving the overall dust removal efficiency. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Such as Figure 1 and Figure 2As shown, a high-efficiency electric bag composite dust collector comprises an outer shell, wherein an electric dust removal zone and a bag dust removal zone are distributed on the left and right sides of the outer shell, dust collecting hoppers are arranged below the electric dust removal zone and the bag dust removal zone, an inlet pipe is arranged on the left side of the outer shell, an outlet pipe is arranged on the upper right side of the outer shell, a guide structure is arranged between the electric dust removal zone and the bag dust removal zone, the guide structure comprises a first guide plate arranged in a vertical direction, a second guide plate inclined downward toward the bag structure side in the bag dust removal zone is arranged below the first guide plate, a third guide plate is further arranged below the bags in the bag dust removal zone, the third guide plate comprises a ventilation plate, a fan-shaped notch and a plurality of ventilation holes are arranged on the ventilation plate, an extension plate is arranged on the outer periphery of the third guide plate downward toward the side away from the third guide plate, and the third guide plate is rotatably connected to the bag dust removal zone.

[0017] Furthermore, the first guide plate is arc-shaped, with both ends extending into the bag dust removal area, and leaving a gap between the front and rear side walls of the outer shell, and contacting the right side wall.

[0018] Furthermore, the third guide plate is arranged to be inclined downward from the center to the edge.

[0019] Furthermore, a connecting rod is provided upwardly from the center of the third guide plate, and the connecting rod is connected to the flower plate provided in the bag dust removal area through a bearing, an auxiliary housing is provided on the right side of the outer shell, a driving motor is provided above the auxiliary housing, and the output shaft of the driving motor extends into the auxiliary housing and is connected to the connecting rod or the extension plate through a transmission structure.
