AI Technical Summary
The existing wet electrostatic precipitator has a slight air leakage problem in the welded seal between the air inlet/outlet and the flange of the housing. In addition, the sealing gasket is prone to deformation and shrinkage during use, which leads to air leakage, affecting the sealing performance and equipment maintenance.
The sealing structure includes first and second flanges. A fixing groove is formed by setting first and second barrier plates. The sealing element is sleeved on the flange. The rubber barrier plate is tightly attached to the inner side of the flange to form an I-shaped cross section, which enhances the sealing effect and prevents shrinkage and deformation after long-term use.
It effectively prevents the gaps in the seals from widening due to prolonged use, improves the sealing effect, prevents air leakage, and extends the service life of the sealed connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector sealing, and in particular to a sealing structure for a wet electrostatic precipitator. Background Technology
[0002] The inlet and outlet of the existing wet electrostatic precipitator are sealed with rubber gaskets and welded together with the flange of the precipitator body. Due to the possibility of flange deformation during welding, there will be slight air leakage at the inlet and outlet of the wet electrostatic precipitator, resulting in poor sealing performance. In addition, the welding connection is not conducive to the maintenance of the equipment. Furthermore, during use, the gasket will deform, shrink and thin, resulting in gaps and air leakage. Utility Model Content
[0003] One objective of this invention is to provide a sealing structure for a wet electrostatic precipitator that at least solves one of the aforementioned technical problems.
[0004] A further objective of this invention is to prevent air leakage caused by long-term use of the sealing gasket.
[0005] Another further objective of this invention is to improve the sealing effect and extend the service life of the sealed connection.
[0006] In particular, this utility model provides a sealing structure for a wet electrostatic precipitator, including a first connecting channel and a second connecting channel, wherein a first flange and a second flange are respectively provided at the flared ends of the first connecting channel and the second connecting channel, and the first flange and the second flange are arranged opposite to each other.
[0007] A sealing element is disposed between the first connecting channel and the second connecting channel, and the sealing element has a first fixing groove and a second fixing groove, wherein the first flange and the second flange are respectively fitted into the first fixing groove and the second fixing groove.
[0008] Furthermore, the sealing element includes a first barrier piece and a second barrier piece, the first barrier piece surrounding the outer side of the first flange and the second flange, and the second barrier piece closely abutting the inner side where the first flange and the second flange connect.
[0009] Furthermore, the cross-section of the seal is I-shaped.
[0010] Furthermore, the seal is made of rubber.
[0011] Furthermore, a plurality of through holes are provided between the first barrier plate and the second barrier plate for the nut to pass through.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This invention incorporates a first barrier plate and a second barrier plate, forming a first fixing groove and a second fixing groove between them. In use, the first flange and the second flange are fitted into the first fixing groove and the second fixing groove, allowing the first barrier plate and the second barrier plate to cover the first flange and the second flange. After prolonged use, the sealing element will shrink, causing the first barrier plate and the second barrier plate to fit tightly against the outside of the first flange and the flange and the gap between them. This prevents the sealing element from shrinking due to prolonged use, thus avoiding air leakage. Attached Figure Description

[0024] This embodiment provides a sealing structure for a wet electrostatic precipitator, including a first connecting channel 1, a second connecting channel 2, and a sealing element 3. The first connecting channel 1 and the second connecting channel 2 are connected at flared interfaces. During use, the flared interfaces provide a larger space, which can slow down the air intake speed. The flared interfaces of the first connecting channel 1 and the second connecting channel 2 are respectively provided with a first flange 101 and a second flange 201, which are fixedly connected by nuts 4. The first flange 101 and the second flange 201 are arranged opposite to each other. The sealing element 3 is disposed between the first connecting channel 1 and the second connecting channel 2, and the sealing element 3 has a first fixing groove 301 and a second fixing groove 302 formed by a first barrier plate 303 and a second barrier plate 304. The first flange 101 and the second flange 201 are respectively fitted into the first fixing groove 301 and the second fixing groove 302, so that the gap at the connection is tightly fitted to the first fixing groove 301 and the second fixing groove 302, preventing the gap from becoming too large when the seal contracts, thus affecting the sealing effect.
[0025] It should be further explained that the sealing element 3 includes a first barrier 303 and a second barrier 304. The first barrier 303 surrounds the outer side of the first flange 101 and the second flange 201, and the second barrier 304 is tightly attached to the inner side where the first flange 101 and the second flange 201 connect. It should be noted that the first barrier 303 and the second barrier 304 are an integral structure. In use, the interior is sealed by the second barrier 304. Because it is tightly attached to the inner wall of the connecting channel, when the internal pressure is high, the second barrier 304 will be forced to press tightly against the inner wall, covering the connection gap between the first flange 101 and the second flange 201. Thus, the greater the internal pressure, the better the sealing effect.
[0026] It should be further noted that the cross-section of the seal 3 is I-shaped, such as... Figure 6 As shown in the image.
[0027] It should be further noted that the seal 3 is made of rubber.
[0028] It should be further noted that a plurality of through holes are provided between the first barrier plate 303 and the second barrier plate 304 for the nut 4 to pass through.
[0029] Working principle of this utility model:
[0030] In use, by providing a first barrier plate 303 and a second barrier plate 304, a first fixing groove 301 and a second fixing groove 302 are formed between the first barrier plate 303 and the second barrier plate 304. In use, the first flange plate 101 and the second flange plate 201 are fitted into the first fixing groove 301 and the second fixing groove 302, so that the first barrier plate 303 and the second barrier plate 304 can cover the first flange and the second flange. After long-term use, the sealing element 3 will shrink and become smaller. When the sealing element 3 shrinks and becomes smaller, the first barrier plate 303 and the second barrier plate 304 will be tightly attached to the outside of the first flange plate 101 and the second flange plate 201 and the gap between them, thereby avoiding the gap from widening due to the shrinkage of the sealing element 3 after long-term use and preventing air leakage.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
