During the movement, part of the moisture in the adsorption layer is scraped off, and because the spring 1 has a certain contraction stroke, the scraper can move from the surface of one of the adsorption layers, pass over the surface of the mounting frame, and then move horizontally to the surface of the other adsorption layer.

[0020] 3. When the connecting seat drives the moving seat and the scraper to move, the moving seat will collide with the resistance block, thereby driving the resistance block and the sealing plate to move together. The liquid pushed down from the adsorption layer will first flow into the leakage groove. When the sealing plate is opened, it can flow downward into the liquid collecting unit. When the sealing plate moves, it will drive the L-shaped connecting block to move together. The L-shaped connecting block moves in the direction away from the ventilation end of the dust collector. The second spring is stretched and deformed, so that the sealing plate can be reset, which is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] Reference Figure 1-Figure 6 , a wet electrostatic precipitator anti-droplet carrying ultra-clean demisting device, comprising two mounting frames 2 fixed in the ventilation end 1 of the dust collector, each mounting frame 2 is fixed with an adsorption layer 3, two movable seats 4 are symmetrically arranged in the ventilation end 1 of the dust collector, the adsorption layer 3 is located between the two movable seats 4, and a side groove 5 is opened at one end of the movable seat 4 facing the adsorption layer 3, a connecting plate 6 is movably arranged in the side groove 5, a scraper 7 is fixed at one end of the connecting plate 6 close to the adsorption layer 3, and the end of the scraper 7 close to the adsorption layer 3 is in an arc shape, and an elastic unit 1 is fixed between each connecting plate 6 and the inner wall of the corresponding side groove 5, a driving assembly for use with the movable seat 4 is arranged on the ventilation end 1 of the dust collector, and a collecting assembly is arranged on the ventilation end 1 of the dust collector.

[0030] In the initial state, the two scrapers 7 abut against the position between the two mounting frames 2 .

[0031] During use, after the gas enters the ventilation end 1 of the dust collector, it will pass through the adsorption layer 3, and the tiny water droplets and water vapor in the gas will be adsorbed by the set adsorption layer 3. When the adsorption layer 3 adsorbs a certain amount of moisture, the driving component drives the two moving seats 4 to move, thereby driving the two scrapers 7 to move. When the two scrapers 7 move from the mounting frame 2 to the surface of the adsorption layer 3, the two scrapers 7 clamp the adsorption layer 3 between the two scrapers 7 under the action of the elastic unit 1. In the process of the moving seat 4 driving the two scrapers 7 to move, the moisture in the adsorption layer 3 will be squeezed out and then discharged into the collection component, which is easy to use, so that the adsorption layer 3 can continuously and efficiently adsorb the water mist in the gas to avoid affecting the subsequent gas treatment and discharge.

[0032] Each elastic unit includes a plurality of springs 8 fixed between the connecting plate 6 and the side groove 5.

[0033] By setting the spring 18, when the adsorption layer 3 is clamped between the two scrapers 7, the spring 18 is still in a squeezed and contracted state, thereby applying a directional force to the connecting plate 6 and the scraper 7, so that the two scrapers 7 can contact the surface of the adsorption layer 3. During the movement, part of the moisture in the adsorption layer 3 is scraped off, and because the spring 18 has a certain contraction stroke, the scraper 7 can move from the surface of one of the adsorption layers 3, pass over the surface of the mounting frame 2, and then move horizontally to the surface of the other adsorption layer 3.

[0034] A plurality of inclined grooves 9 are formed on the inner wall of each installation frame 2 .

[0035] On the one hand, it is convenient for the scraper 7 to pass over the mounting frame 2 during use, and on the other hand, it is convenient for the water squeezed out of the adsorption layer 3 to be drained away.

[0036] A connecting seat 10 is fixed to a side of each movable seat 4 away from the adsorption layer 3 , and a plurality of guide posts 11 are symmetrically fixed to the inner wall of the dust collector ventilation end 1 , and each guide post 11 movably passes through the corresponding connecting seat 10 .

[0037] The connecting seat 10 , the moving seat 4 and the scraper 7 are guided by the guide column 11 .

[0038] The driving assembly includes two screw rods 12 symmetrically rotatably arranged in the ventilation end 1 of the dust collector. Each screw rod 12 is threaded through the corresponding connecting seat 10. A motor 13 for driving one of the screw rods 12 to rotate is fixed on the outer wall of the ventilation end 1 of the dust collector. A linkage unit is arranged between the two screw rods 12. The motor 13 drives the corresponding connected screw rod 12 to rotate, which is the prior art.

[0039] The linkage unit includes two connecting shafts 14, each connecting shaft 14 is fixed to the end of the corresponding screw rod 12, and the end of each connecting shaft 14 rotates through the side wall of the dust collector ventilation end 1 and is fixedly sleeved with a pulley 15, and a transmission belt 16 is sleeved between the two pulleys 15.

[0040] When the motor 13 drives the corresponding screw rod 12 to rotate, the screw rod 12 will drive the corresponding connecting shaft 14 and the pulley 15 to rotate, thereby driving another pulley 15, the connecting shaft 14 and the screw rod 12 to rotate through the transmission belt 16, thereby driving the two connecting seats 10 to move.

[0041] The collecting assembly includes two leakage grooves 18 symmetrically opened at the bottom of the ventilation end 1 of the dust collector. The length of the leakage grooves 18 is smaller than the size of each single mounting frame 2 to prevent the lower end of the mounting frame 2 from being in a suspended state. A sealing plate 19 is slidably arranged in the leakage grooves 18. One end of each sealing plate 19 is movable and penetrates to the outside of the ventilation end 1 of the dust collector. An elastic unit 2 is arranged between each sealing plate 19 and the ventilation end 1 of the dust collector. A resistance block 20 is fixed to the upper end surface of each sealing plate 19 and the end close to the movable seat 4. The lower end surface of the ventilation end 1 of the dust collector is symmetrically provided with two liquid collecting units used in conjunction with the corresponding leakage grooves 18.

[0042] In the initial state, the blocking plate 19 blocks the leakage groove 18 .

[0043] Each elastic unit 2 includes an L-shaped connecting block 21 fixed to the end of the blocking plate 19, and a spring 22 is fixed between the L-shaped connecting block 21 and the outer side wall of the ventilation end 1 of the dust collector.

[0044] When the connecting seat 10 drives the moving seat 4 and the scraper 7 to move, the moving seat 4 will collide with the resistance block 20, thereby driving the resistance block 20 and the sealing plate 19 to move together. The liquid pushed down from the adsorption layer 3 first flows into the leakage groove 18. When the sealing plate 19 is opened, it can flow downward into the liquid collecting unit. When the sealing plate 19 moves, it will drive the L-shaped connecting block 21 to move together. The L-shaped connecting block 21 moves in the direction away from the ventilation end 1 of the dust collector, and the spring 22 is stretched and deformed, so that the sealing plate 19 can be reset, which is convenient to use.

[0045] Each liquid collecting unit includes a collecting box 23 fixed to the lower end surface of the ventilation end 1 of the dust collector, and each leakage groove 18 penetrates into the collecting box 23. A drain pipe 24 is connected to one side of the collecting box 23, and a valve is provided on the drain pipe 24. A liquid level sensor can be set in the collecting box 23.

[0046] During use, the squeezed liquid eventually drips into the collection box 23 . When the collection box 23 is almost full, the valve on the drain pipe 24 is opened to drain the liquid in the collection box 23 .

[0047] When the present invention is in use, in the initial state, the two scrapers 7 are against the position between the two mounting frames 2. After the gas enters the ventilation end 1 of the dust collector, it will pass through the adsorption layer 3, and the tiny water droplets and water vapor in the gas will be adsorbed by the arranged adsorption layer 3. After the adsorption layer 3 adsorbs a certain amount of moisture, the driving component drives the two moving seats 4 to move, thereby driving the two scrapers 7 to move. When the two scrapers 7 move from the mounting frame 2 to the surface of the adsorption layer 3, the two scrapers 7 clamp the adsorption layer 3 between the two scrapers 7 under the action of the elastic unit 1. In the process of the moving seat 4 driving the two scrapers 7 to move, the moisture in the adsorption layer 3 will be squeezed out and then discharged into the collecting component, which is convenient to use, so that the adsorption layer 3 can continuously and efficiently adsorb the water mist in the gas to avoid affecting the subsequent gas processing and discharge.

[0048] By setting the spring 1 8, when the adsorption layer 3 is clamped between the two scrapers 7, the spring 1 8 is still in a squeezed and contracted state, thereby applying a directional force to the connecting plate 6 and the scraper 7, so that the two scrapers 7 can contact the surface of the adsorption layer 3, and in the process of moving, a part of the moisture in the adsorption layer 3 is scraped off, and because the spring 1 8 has a certain contraction stroke, the scraper 7 can move from the surface of one adsorption layer 3 to the surface of the other adsorption layer 3 after crossing the surface of the mounting frame 2;

[0049] In the initial state, the blocking plate 19 blocks the leakage groove 18. When the connecting seat 10 drives the moving seat 4 and the scraper 7 to move, the moving seat 4 will contact the resistance block 20, thereby driving the resistance block 20 and the blocking plate 19 to move together. The liquid pushed down from the adsorption layer 3 first flows into the leakage groove 18. When the blocking plate 19 is opened, it can flow downward into the liquid collecting unit. When the blocking plate 19 moves, it will drive the L-shaped connecting block 21 to move together. The L-shaped connecting block 21 moves in the direction away from the ventilation end 1 of the dust collector, and the spring 22 is stretched and deformed, so that the blocking plate 19 can be reset, which is convenient to use.

[0050] During use, the squeezed liquid eventually drips into the collection box 23 . When the collection box 23 is almost full, the valve on the drain pipe 24 is opened to drain the liquid in the collection box 23 .

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
