[0003] A Chinese patent discloses a wet electrostatic precipitator for corrosion-resistant flue gas with an authorization announcement number (CN218076703U). The patented technology uses a filter to initially filter the sewage entering the separation chamber to achieve solid-liquid separation, so that the dust particles remain on the surface of the filter. The liquid passes through the filter and falls in the middle of the filter drawer for secondary filtration. The filtered liquid is discharged through a drain pipe.

DETAILED DESCRIPTION

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Reference Figure 5 and Figure 6As shown, in this embodiment: both sides of the upper shell 9 are fixedly connected with a slide plate 13, and the two ends of the top of the bottom shell 1 are fixedly connected to the limit shell 14, and the surface of the slide plate 13 is slidably connected to the inner wall of the limit shell 14. When the staff inserts the second gasket 8 into the inner wall of the circular groove 6, the position of the upper shell 9 on the top of the bottom shell 1 is restricted by inserting the slide plate 13 into the inner wall of the limit shell 14, so that the insertion of the limit plate 3 and the limit groove 12 is more precise, preventing the upper shell 9 and the bottom shell 1 from rotating during installation.

[0026] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment: a sliding groove 15 is opened inside the limit plate 3, and the inner wall of the sliding groove 15 is slidably connected with a sliding rod 16, and the end of the sliding rod 16 close to the L-shaped plate 5 is fixedly connected to the L-shaped plate 5. When the limit plate 3 moves under the elastic force of the spring 4, the sliding connection between the sliding rod 16 and the sliding groove 15 limits the moving trajectory of the limit plate 3, so that the limit plate 3 can be more accurately plugged into the limit groove 12.

[0027] Reference Figure 4 As shown, in the present embodiment: a threaded hole 17 is provided on the top of the L-shaped plate 5, and a threaded rod 18 is threadedly connected to the inner wall of the threaded hole 17. The staff screws the threaded rod 18 out of the bottom of the threaded hole 17, so that the threaded rod 18 abuts against the surface of the sliding rod 16 and the limit plate 3, thereby fixing the position of the limit plate 3, preventing the spring 4 from shaking and loosening, causing the limit plate 3 to detach from the limit groove 12, and facilitating the staff to fix the position of the limit plate 3.

[0028] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment: the inner diameter of the spring 4 is slidably connected to the surface of the slide rod 16. When the spring 4 rebounds, the rebound trajectory of the spring 4 is limited by the sliding connection between the spring 4 and the slide rod 16, so that the spring 4 moves on the surface of the slide rod 16, preventing the spring 4 from curling up when rebounding and causing winding to affect the normal operation of the component.

[0029] Reference Figure 6 and Figure 7 As shown, in the present embodiment: an arc plate 19 is fixedly connected to the top of the inner wall of the upper shell 9, and a plurality of air vents 20 are opened on the surface of the arc plate 19. The arc plate 19 is arranged at the bottom of the outlet of the air inlet pipe 10 so that the flue gas can pass through the arc surface design of the arc plate 19 and then flow out through the air vents 20, thereby diffusing the flue gas flowing into the air inlet pipe 10, preventing the flue gas discharged from the air inlet pipe 10 from being purified for a long time through one part of the wet electrostatic precipitator assembly 11, thereby increasing the overall utilization area of ​​the air inlet pipe 10.

[0030] Reference Figure 5 and Figure 6 As shown, in the present embodiment: the first gasket 7 and the second gasket 8 are both made of silicone material. By adopting the silicone design for the first gasket 7 and the second gasket 8, the first gasket 7 and the second gasket 8 have soft properties and fit more closely, thereby preventing the gas from the inner wall from overflowing, thereby improving the air tightness of the connection of the device. At the same time, the silicone material has the property of corrosion resistance and a longer service life.

[0031] Working principle: The staff pulls one end of the limit plate 3 to drive the spring 4 to store force, and then inserts the second gasket 8 into the circular groove 6, so that the second gasket 8 is in close contact with the first gasket 7, and then loosens the limit plate 3 to release the restraint on the spring 4, so that the spring 4 releases the force generated and rebounds and pulls one end of the limit plate 3. Through the rotation connection between the limit plate 3 and the rotating rod 2, the other end of the limit plate 3 is inserted into the inner wall of the limit groove 12 to fix the position of the upper shell 9, so that the bottom shell 1 and the upper shell 9 can be detached, which is convenient for the staff to disassemble the device and take out the wet electrostatic precipitator component 11 for maintenance. The invention can be convenient for the staff to disassemble the device, reduce the occupied space and facilitate transportation. When the staff inserts the second gasket 8 into the inner wall of the circular groove 6, the position of the upper shell 9 on the top of the bottom shell 1 is limited by inserting the slide plate 13 into the inner wall of the limit shell 14, so that the plugging of the limit plate 3 and the limit groove 12 is more accurate, and the upper shell 9 and the bottom shell 1 are prevented from rotating when being installed. When the limit plate 3 moves under the elastic force of the spring 4, the sliding connection between the slide bar 16 and the slide groove 15 is used to limit the movement trajectory of the limit plate 3, so that the limit plate 3 can be more accurately inserted into the limit groove 12. Then, the staff screws the threaded rod 18 out of the bottom of the threaded hole 17, so that the threaded rod 18 abuts against the surface of the slide bar 16 and the limit plate 3, thereby fixing the position of the limit plate 3 and preventing the spring 4 from shaking and loosening, causing the limit plate 3 to disengage from the limit groove 12, which is convenient for the staff to fix the position of the limit plate 3. When the spring 4 rebounds, the rebound trajectory of the spring 4 is limited by the sliding connection between the spring 4 and the slide bar 16, so that the spring 4 moves on the surface of the slide bar 16, preventing the spring 4 from curling up and causing winding when it rebounds, affecting the normal operation of the component, and then at the outlet of the intake pipe 10 The arc plate 19 arranged at the bottom allows the flue gas to pass through the arc surface design of the arc plate 19 and then flow out through the vent hole 20, thereby diffusing the flue gas flowing into the air intake pipe 10, preventing the flue gas discharged from the air intake pipe 10 from being purified through one part of the wet electrostatic precipitator assembly 11 for a long time, thereby increasing the overall use area of ​​the air intake pipe 10, and by adopting silicone design for the first gasket 7 and the second gasket 8, the first gasket 7 and the second gasket 8 have soft properties and fit more closely, preventing the gas from the inner wall from overflowing, thereby improving the air tightness of the connection of the device, and at the same time, the silicone material has the property of corrosion resistance and a longer service life.
