Description
Technical Field
[0001] This utility model relates to the field of separation device technology, specifically to a dust-water separation device for a wet electrostatic precipitator. Background Technology
[0002] Early wet electrostatic precipitators used lead as the main raw material, but lead has poor mechanical properties and is prone to problems when operating at high temperatures for a long time. For example, leakage may occur due to the operating pressure and pulse pressure of downstream acid production equipment, which may cause severe corrosion of the metal under the equipment and even lead to the scrapping of the equipment. Later, people used chemically stable metal materials to replace lead, which solved the corrosion problem and promoted the continuous development of wet electrostatic precipitators.
[0003] In existing technologies, coal chemical processes such as coal gasification and coal liquefaction generate a large amount of dust-laden coal gas. When wet electrostatic precipitators are used to purify coal gas, the dust-water separation device can separate the dust-laden water generated during the dust removal process. However, during use, the separation device usually does not perform initial separation of dirt and dust in the dust-water, which can easily put a heavy burden on the subsequent filter screens. Moreover, when the filter screens need to be cleaned and maintained, disassembling the filter screens is usually quite troublesome, greatly increasing the equipment maintenance time.
[0004] Therefore, a dust-water separation device for wet electrostatic precipitators is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a dust-water separation device for a wet electrostatic precipitator, which solves the technical problem that separation devices usually do not perform initial separation of dirt and dust in the dust and water, which easily puts a heavy burden on the subsequent filter screen. Moreover, when the filter screen needs to be cleaned and maintained, it is usually quite troublesome to disassemble the filter screen, which greatly increases the maintenance time of the equipment. The present invention achieves the purpose of initial rotational separation and separation disassembly.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust-water separation device for a wet electrostatic precipitator, comprising a separation box, a drain pipe connected to the bottom of the separation box, a separation pipe connected to the top of the separation box, a cover plate provided on the top of the separation pipe, a primary rotation separation component provided inside the separation pipe, and a separation disassembly component provided inside the separation box.
[0007] Preferably, the initial rotational separation assembly specifically includes: an inlet pipe, which is equidistantly connected and installed on the top of the cover plate; a support plate, which is fixedly installed between the inner walls of the separation tube; a servo motor, which is fixedly installed on the top of the cover plate; a connecting block, which is circumferentially fixedly installed on the inner wall surface of the separation tube; and a motor, which is fixedly installed on the top of the cover plate.
[0008] Preferably, a separation cylinder is rotatably connected to the top of the support plate, and the outer wall of the separation cylinder has holes at equal intervals. A filter screen is fixedly installed between the inner walls of the holes, and a gear sleeve is fixedly fitted on the outer wall of the separation cylinder.
[0009] Preferably, the output end of the servo motor is fixedly mounted with a rotating shaft, the other end of the rotating shaft movably passes through the top of the cover plate and extends to the bottom of the cover plate, and a gear is fixedly mounted on the other end of the rotating shaft, the surface of the gear meshing with the surface of the gear sleeve.
[0010] Preferably, a sealing plate is fixedly connected to the other side of the connecting block, and a sealing gasket is fixedly installed on the inner side of the sealing plate. The inner side of the sealing gasket is in contact with the outer wall of the separation cylinder. A second rotating shaft is fixedly installed at the output end of the motor. The other end of the second rotating shaft movably passes through the top of the cover plate and extends to the bottom of the cover plate. A connecting rod is fixedly installed at the other end of the second rotating shaft. The bottom of the connecting rod extends into the interior of the separation cylinder. Rotating blades are fixedly installed equidistantly on the outer circumference of the connecting rod. The dust-water mixture is introduced into the separation cylinder through the liquid inlet pipe, so that the separation cylinder is filled with dust and water. After reaching a certain capacity, the servo motor drives the gear to rotate. Through meshing with the gear sleeve, the separation cylinder rotates, and the sealing gasket can be separated from the filter screen. Then, the motor drives the connecting rod and the rotating blades to rotate inside the separation cylinder. During the rotation, the centrifugal force can be used to quickly throw larger dust particles in the dust-water mixture to the outside of the separation cylinder, and achieve preliminary dust-water separation through the filter screen, thereby achieving the effect of initial rotational separation.
[0011] Preferably, the separation and disassembly assembly specifically includes: a sealing plate, equidistantly disposed on one side of the separation box; a handle, fixedly installed on one side of the sealing plate; support blocks, equidistantly fixedly installed on both sides of the inner wall of the separation box; and a hollow block, equidistantly fixedly installed on one side of the separation box.
[0012] Preferably, the other side of the sealing plate extends through one side of the separation box and into the interior of the separation box. A sealing sleeve is fixedly installed on the outer wall of the sealing plate, and the outer wall of the sealing sleeve fits against the inner wall of the separation box. A sealing frame is fixedly installed on the other side of the sealing plate, and the outer wall of the sealing frame fits against the inner wall of the separation box. A corrugated filter screen is fixedly installed between the inner walls of the sealing frame, and the bottom of the sealing frame contacts the top of the support block.
[0013] Preferably, the inner wall of the hollow block is slidably connected to an insert rod, the bottom of which movably passes through the top of the handle and extends to the bottom of the handle. A compression sleeve is fixedly fitted onto the outer wall of the insert rod, and a push plate is fixedly connected to the outer wall of the compression sleeve. A spring is movably fitted onto the outer wall of the insert rod, one end of which is fixedly connected to the bottom of the hollow block, and the other end is fixedly connected to the top of the compression sleeve. The sealing plate can be easily pulled out or inserted from the separation box via the handle, facilitating cleaning, replacement, or maintenance of the corrugated filter screen. Compared to ordinary flat filter screens, the corrugated filter screen increases the filtration area, more effectively intercepting fine particles in dust and water, improving the accuracy and efficiency of dust-water separation. The support block provides stable support for the sealing frame. The fixing structure composed of the insert rod, compression sleeve, push plate, and spring can firmly fix the sealing plate inside the separation box. The elasticity of the spring ensures that the insert rod is always in the appropriate position, preventing the sealing plate from loosening during equipment operation, ensuring the stability of the entire separation and disassembly assembly, thereby achieving the effect of separation and disassembly.
[0014] This utility model provides a dust-water separation device for a wet electrostatic precipitator. It has the following beneficial effects:
[0015] (1) This utility model can perform initial separation of dust and water by setting up an initial rotation separation component. Dust and water enter the separation cylinder through the liquid inlet pipe. At this time, the sealing gasket seals the filter screen. After reaching a certain capacity, the servo motor is started to drive the gear to rotate, and drive the gear sleeve and the separation cylinder to rotate. The sealing gasket is released from the seal on the filter screen. Then, the motor is started at the same time to drive the connecting rod and rotating blades to rotate the dust and water in the separation cylinder, so that the dust and water generate centrifugal force. The water falls into the separation box through the filter screen, realizing the initial separation of dust and water. This can effectively reduce the burden of subsequent separation links, thereby achieving the effect of initial rotation separation.
[0016] (2) This utility model can disassemble and clean the filter device by setting a separation and disassembly component. The two-layer corrugated filter screen can perform deep filtration of dust and water. The corrugated filter screen increases the filtration area and can more effectively intercept fine particles in dust and water. When the corrugated filter screen needs to be cleaned, push the push plate to drive the squeezing sleeve and the insertion rod upward and compress the spring. The insertion rod disengages from the handle. The sealing plate and sealing frame are taken out from the separation box through the handle, which greatly shortens the maintenance time of the equipment and reduces the maintenance cost, thereby achieving the effect of separation and disassembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] Example 1:
[0025] The existing separation devices typically do not perform initial separation of dust and dirt from the dust-water mixture, which easily places a heavy burden on subsequent filters. Furthermore, cleaning and maintenance of the filters, including disassembly, are usually cumbersome, significantly increasing equipment maintenance time. Therefore, this utility model provides a preferred embodiment of a dust-water separation device for a wet electrostatic precipitator, for example… Figure 1-4 As shown: A dust-water separation device for a wet electrostatic precipitator includes a separation box 1, a drain pipe 2 connected to the bottom of the separation box 1, a separation pipe 3 connected to the top of the separation box 1, a cover plate on the top of the separation pipe 3, a primary rotation separation component 4 inside the separation pipe 3, and a separation disassembly component 5 inside the separation box 1.
[0026] The initial rotation separation assembly 4 specifically includes: an inlet pipe 411, which is equidistantly connected and installed on the top of the cover plate; a support plate 412, which is fixedly installed between the inner walls of the separation tube 3; a servo motor 416, which is fixedly installed on the top of the cover plate; a connecting block 418, which is circumferentially fixedly installed on the inner wall surface of the separation tube 3; and a motor 4112, which is fixedly installed on the top of the cover plate.
[0027] A separation cylinder 413 is rotatably connected to the top of the support plate 412. Holes are equidistantly opened on the outer wall of the separation cylinder 413. A filter screen 414 is fixedly installed between the inner walls of the holes. A gear sleeve 415 is fixedly fitted on the outer wall of the separation cylinder 413.
[0028] The output end of the servo motor 416 is fixedly mounted with a rotating shaft 1. The other end of the rotating shaft 1 movably passes through the top of the cover plate and extends to the bottom of the cover plate. The other end of the rotating shaft 1 is fixedly mounted with a gear 417. The surface of the gear 417 meshes with the surface of the gear sleeve 415.
[0029] A sealing plate 419 is fixedly connected to the other side of the connecting block 418. A sealing gasket 4111 is fixedly installed on the inner side of the sealing plate 419. The inner side of the sealing gasket 4111 is in contact with the outer wall of the separation cylinder 413. A rotating shaft 2 is fixedly installed at the output end of the motor 4112. The other end of the rotating shaft 2 moves through the top of the cover plate and extends to the bottom of the cover plate. A connecting rod 4113 is fixedly installed at the other end of the rotating shaft 2. The bottom of the connecting rod 4113 extends into the interior of the separation cylinder 413. Rotating blades 4114 are fixedly installed at equal intervals around the outer circumference of the connecting rod 4113.
[0030] In this example, the initial rotational separation component 4 is set up to perform the initial separation of dust and water. The dust and water enter the separation cylinder 413 through the liquid inlet pipe 411. At this time, the sealing gasket 4111 seals the filter screen 414. After a certain capacity is reached, the servo motor 416 is started to drive the gear 417 to rotate, and drive the gear sleeve 415 and the separation cylinder 413 to rotate 90 degrees. The sealing gasket 4111 is released from the seal on the filter screen 414. Then, the motor 4112 is started at the same time to drive the connecting rod 4113 and the rotating blade 4114 to rotate the dust and water in the separation cylinder 413, so that the dust and water generate centrifugal force. The water falls into the separation box 1 through the filter screen 414, thereby achieving the effect of initial rotational separation.
[0031] Example 2:
[0032] Based on Embodiment 1, a preferred embodiment of the dust-water separation device for a wet electrostatic precipitator provided by this utility model is as follows: Figure 1-4As shown: The separation and disassembly assembly 5 specifically includes: a sealing plate 511, which is equidistantly arranged on one side of the separation box 1; a handle 513, which is fixedly installed on one side of the sealing plate 511; a support block 516, which is equidistantly fixedly installed on both sides of the inner wall of the separation box 1; and a hollow block 517, which is equidistantly fixedly installed on one side of the separation box 1.
[0033] The other side of the sealing plate 511 extends through one side of the separation box 1 and into the interior of the separation box 1. A sealing sleeve 512 is fixedly installed on the outer wall of the sealing plate 511. The outer wall of the sealing sleeve 512 fits against the inner wall of the separation box 1. A sealing frame 514 is fixedly installed on the other side of the sealing plate 511. The outer wall of the sealing frame 514 fits against the inner wall of the separation box 1. A corrugated filter screen 515 is fixedly installed between the inner walls of the sealing frame 514. The bottom of the sealing frame 514 contacts the top of the support block 516.
[0034] A rod 518 is slidably connected to the inner wall of the hollow block 517. The bottom of the rod 518 moves through the top of the handle 513 and extends to the bottom of the handle 513. A compression sleeve 519 is fixedly fitted on the outer wall of the rod 518. A push plate 5111 is fixedly connected to the outer wall of the compression sleeve 519. A spring 5112 is movably fitted on the outer wall of the rod 518. One end of the spring 5112 is fixedly connected to the bottom of the hollow block 517, and the other end of the spring 5112 is fixedly connected to the top of the compression sleeve 519.
[0035] In this example, the filter device can be disassembled and cleaned by setting the separation and disassembly component 5. The two-layer corrugated filter screen 515 can perform deep filtration of dust and water. The corrugated filter screen 515 increases the filtration area and can more effectively intercept fine particles in dust and water. When it is necessary to clean the corrugated filter screen 515, push the push plate 5111 to drive the compression sleeve 519 and the insertion rod 518 upward, and compress the spring 5112. The insertion rod 518 disengages from the handle 513. The sealing plate 511 and the sealing frame 514 can be taken out from the separation box 1 through the handle 513, thereby achieving the function of separation and disassembly.
[0036] Working Principle: First, during use, the cover plate is fixedly connected to the separation tube 3 with bolts to ensure stability during separation. Dust and water enter the separation cylinder 413 through the inlet pipe 411. At this time, the sealing gasket 4111 seals the filter screen 414. After reaching a certain capacity, the servo motor 416 is started to drive the gear 417 to rotate, which in turn drives the gear sleeve 415 and the separation cylinder 413 to rotate 90 degrees. The sealing gasket 4111 releases its seal on the filter screen 414. Then, the motor 4112 is started simultaneously to drive the connecting rod 4113 and the rotating blades 4114 to rotate the dust and water in the separation cylinder 413, causing the dust and water to generate centrifugal force. The water falls into the separation box 1 through the filter screen 414. The larger dust particles in the dust and water are initially separated by the swirling effect, reducing the load on the subsequent filter screen. Then, when the dirt and dust in the separation cylinder 413 accumulate to a certain extent, the operator can separate the cover plate from the separation tube 3 with bolts, and then clean the inside of the separation cylinder 413. The liquid that was initially filtered can then be deeply filtered through the second layer of corrugated filter screen 515. The corrugated filter screen 515 increases the filtration area and can more effectively intercept fine particles in the dust and water. When it is necessary to clean the corrugated filter screen 515, push the push plate 5111 to drive the squeezing sleeve 519 and the insertion rod 518 upward, and compress the spring 5112. The insertion rod 518 disengages from the handle 513. The sealing plate 511 and the sealing frame 514 are removed from the separation box 1 through the handle 513. Then the corrugated filter screen 515 is cleaned and maintained, thereby achieving the function of initial rotation separation and separation disassembly.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
