[0006] And a proposed ultra-clean demisting device for preventing fog droplet carryover in a wet electrostatic precipitator is provided.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

An adsorption layer is fixed inside each mounting frame. Two moving seats are symmetrically arranged inside the ventilation end of the precipitator. The adsorption layer is located between the two moving seats. A side groove is opened at one end of the moving seat facing the adsorption layer. A connecting plate is movably arranged inside the side groove. One end of the connecting plate close to the adsorption layer is fixed with a scraping plate. One end of the scraping plate close to the adsorption layer is arc-shaped. An elastic unit one is fixed between each connecting plate and the inner wall of the corresponding side groove. A driving component for cooperating with the moving seat is arranged on the ventilation end of the precipitator, and a collecting component is arranged on the ventilation end of the precipitator.

[0009] As a further technical solution of the present invention, each of the elastic units 1 includes a plurality of springs 1 fixed between the connecting plate and the side grooves.

[0010] As a further technical solution of the present invention, a plurality of inclined grooves are provided on the inner wall of each of the installation frames.

[0011] As a further technical solution of the present invention, a connecting seat is fixed on the side of each movable seat away from the adsorption layer, and a plurality of guide columns are symmetrically fixed on the inner wall of the ventilation end of the dust collector, and each guide column movably passes through the corresponding connecting seat.

[0012] As a further technical solution of the present invention, the driving assembly includes two screw rods symmetrically rotatably arranged in the ventilation end of the dust collector, each screw rod is threaded through the corresponding connecting seat, a motor for driving one of the screw rods to rotate is fixed on the outer wall of the ventilation end of the dust collector, and a linkage unit is arranged between the two screw rods.

[0013] As a further technical solution of the present invention, the linkage unit includes two connecting shafts, each connecting shaft is fixed to the end of the corresponding screw rod, and the end of each connecting shaft rotates through the side wall of the ventilation end of the dust collector and is fixedly sleeved with a pulley, and a transmission belt is sleeved between the two pulleys.

[0014] As a further technical solution of the present invention, the collecting component includes two liquid leakage grooves symmetrically opened at the bottom of the ventilation end of the dust collector, a sealing plate is slidably arranged in each leakage groove, one end of each sealing plate is movable and penetrates to the outside of the ventilation end of the dust collector, and an elastic unit 2 is arranged between each sealing plate and the ventilation end of the dust collector, a resistance block is fixed on the upper end surface of each sealing plate and one end close to the movable seat, and two liquid collection units used in conjunction with the corresponding liquid leakage grooves are symmetrically arranged on the lower end surface of the ventilation end of the dust collector.

[0015] As a further technical solution of the present invention, each of the elastic units 2 includes an L-shaped connecting block fixed to the end of the blocking plate, and a spring 2 is fixed between the L-shaped connecting block and the outer side wall of the ventilation end of the dust collector.

[0016] As a further technical solution of the present invention, each of the liquid collecting units includes a collecting box fixed to the lower end surface of the ventilation end of the dust collector, each leakage groove penetrates into the interior of the collecting box, and a drain pipe is connected to one side of the collecting box, and a valve is provided on the drain pipe.

[0017] Beneficial effects of the present invention:

[0018] 1. During use, after the gas enters the ventilation end of the dust collector, it will pass through the adsorption layer. The set adsorption layer adsorbs the tiny water droplets and water vapor in the gas. When the adsorption layer adsorbs a certain amount of moisture, the driving component drives the two moving seats to move, thereby driving the two scraping plates to move. When the two scraping plates move from the mounting frame and contact the surface of the adsorption layer, under the action of the first elastic unit, the adsorption layer is clamped between the two scraping plates. During the process of the moving seat driving the two scraping plates to move, the moisture in the adsorption layer will be squeezed out and then discharged into the collection component, which is convenient to use. Thus, the adsorption layer can continuously and efficiently adsorb the water mist in the gas, avoiding affecting the subsequent treatment and discharge of the gas.

[0019] 2. Through the set first spring, when the adsorption layer is clamped between the two scraping plates, the first spring is still in a compressed and contracted state, thereby applying a directional force to the connecting plate and the scraping plate, so that the two scraping plates can contact the surface of the adsorption layer. During the movement, a part of the moisture in the adsorption layer is scraped off. And because the first spring has a certain amount of contraction stroke, the scraping plate can move from the surface of one adsorption layer, cross the surface of the mounting frame, and then translate to the surface of the other adsorption layer.

[0020] 3. When the connecting seat drives the moving seat and the scraping plate to move, the moving seat will contact the abutting block, thereby driving the abutting block and the blocking plate to move together. The liquid pushed off from the adsorption layer first flows into the liquid leakage groove. When the blocking plate is opened, it can flow down into the liquid collection unit. When the blocking 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, and the second spring is stretched and deformed, prompting the blocking plate to reset, which is convenient to use.

[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 Figures 1-6 , 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] Through the arranged first spring 8, when the adsorption layer 3 is clamped between the two scraping plates 7, the first spring 8 is still in a state of being squeezed and contracted, so as to apply a directional force to the connecting plate 6 and the scraping plates 7, so that the two scraping plates 7 can abut against the surface of the adsorption layer 3. During the movement, a part of the moisture in the adsorption layer 3 is scraped off. And because the first spring 8 has a certain contraction stroke, the scraping plate 7 can move from the surface of one adsorption layer 3, cross the surface of the mounting frame 2, and then translate to the surface of the other adsorption layer 3.

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

[0035] On the one hand, during use, it is convenient for the scraping plate 7 to cross the mounting frame 2. On the other hand, it is convenient to drain the water squeezed out from the adsorption layer 3.

[0036] A connecting seat 10 is fixedly arranged on the side of each moving seat 4 away from the adsorption layer 3. A plurality of guide posts 11 are symmetrically and fixedly arranged on the inner wall of the air inlet end 1 of the dust collector. Each guide post 11 movably penetrates through the corresponding connecting seat 10.

[0037] Through the arranged guide posts 11, the translation of the connecting seat 10, the moving seat 4 and the scraping plates 7 is guided.

[0038] The driving assembly includes two lead screws 12 symmetrically and rotatably arranged in the air inlet end 1 of the dust collector. Each lead screw 12 threadedly penetrates through the corresponding connecting seat 10. A motor 13 for driving one of the lead screws 12 to rotate is fixedly arranged on the outer side wall of the air inlet end 1 of the dust collector. A linkage unit is arranged between the two lead screws 12. Driving the corresponding lead screw 12 connected to the motor 13 to rotate is a prior art.

[0039] The linkage unit includes two connecting shafts 14. Each connecting shaft 14 is fixedly arranged at the end of the corresponding lead screw 12. The end of each connecting shaft 14 rotatably penetrates through the side wall of the air inlet end 1 of the dust collector and is fixedly sleeved with a pulley 15. A transmission belt 16 is sleeved between the two pulleys 15.

[0040] When the motor 13 drives the corresponding lead screw 12 to rotate, the lead screw 12 will drive the corresponding connecting shaft 14 and pulley 15 to rotate, so as to drive the other pulley 15, connecting shaft 14 and lead screw 12 to rotate through the transmission belt 16, so as to drive 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 inside the collection box 23 .

[0047] When the present invention is in use, in the initial state, the two scraping plates 7 abut 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. The provided adsorption layer 3 adsorbs the tiny water droplets and water vapor in the gas. When the adsorption layer 3 adsorbs a certain amount of moisture, the driving assembly drives the two moving seats 4 to move, thereby driving the two scraping plates 7 to move. When the two scraping plates 7 move from the mounting frames 2 and abut against the surface of the adsorption layer 3, under the action of the first elastic unit, the two scraping plates 7 clamp the adsorption layer 3 between them. During the process of the moving seat 4 driving the two scraping plates 7 to move, the moisture in the adsorption layer 3 will be squeezed out and then discharged into the collection assembly, which is convenient to use, so that the adsorption layer 3 can continuously and efficiently adsorb the water mist in the gas, avoiding affecting the subsequent treatment and discharge of the gas;

[0048] Through the provided first spring 8, when the adsorption layer 3 is clamped between the two scraping plates 7, the first spring 8 is still in a compressed and contracted state, thereby applying a directional force to the connecting plate 6 and the scraping plate 7, so that the two scraping plates 7 can abut against the surface of the adsorption layer 3. During the moving process, a part of the moisture in the adsorption layer 3 is scraped off, and due to the first spring 8 having a certain contraction stroke amount, the scraping plate 7 can move from the surface of one adsorption layer 3, cross the surface of the mounting frame 2, and then translate to the surface of the other adsorption layer 3;

[0049] In the initial state, the blocking plate 19 blocks the liquid leakage groove 18. When the connecting seat 10 drives the moving seat 4 and the scraping plate 7 to move, the moving seat 4 will abut against the abutting block 20, thereby driving the abutting block 20 and the blocking plate 19 to move together. The liquid pushed off from the adsorption layer 3 first flows into the liquid leakage groove 18. When the blocking plate 19 is opened, it can flow downward into the liquid collection 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 a direction away from the ventilation end 1 of the dust collector, and the second spring 22 is stretched and deformed, prompting the blocking plate 19 to be able to reset, which is convenient to use;

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

[0051] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, within the scope of the technical solution of the present invention, can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes.
