Description

Technical Field

[0001] The invention relates to the technical field of washing towers, in particular to a high-efficiency segmented cyclone countercurrent chemical washing tower and a use method thereof. Background Art

[0002] The scrubber is a new type of gas purification equipment, which is improved on the basis of the floating packing layer gas purifier. It is widely used in pre-treatment of industrial waste gas purification and dust removal, and has a good purification effect. For the coal gasification process, gas scrubbing is inevitable. No matter what coal gasification technology is used, this unit operation is used. Because its working principle is similar to the scrubbing process, it is called a scrubber.

[0003] The problem that the gas inlet of the prior art washing tower is inconvenient to be evenly distributed inside the washing tower causes the gas to be unable to be fully washed. In order to avoid such problems, in view of this: Chinese patent CN218011971U discloses a high-efficiency segmented cyclone countercurrent chemical washing tower. Aiming at the existing problem that the packing layer cannot be replaced and the air entering the washing tower cannot be evenly distributed, the following scheme is proposed, which includes a washing tower, the inner wall of the washing tower is provided with a slide groove, the inner wall of the washing tower on the side away from each other is provided with a first placement block, and the top of the two first placement blocks is placed with the same packing plate. In the utility model, the packing layer placed in the washing tower is replaced by replacing the assembly to avoid the packing layer failure due to long-term use, so that the treatment of the exhaust gas does not meet the standard, and the exhaust gas is better and more evenly discharged into the washing tower through the exhaust assembly, so as to avoid the exhaust gas always entering the packing layer from one area, resulting in the exhaust gas being unable to be fully washed, and the packing layer in this area losing its effect earlier than the packing layer in other areas.

[0004] Although the above method achieves the effect of facilitating uniform gas distribution, it inevitably requires an additional driving source, which leads to a further increase in the energy consumption of the device. In order to avoid such problems, a high-efficiency segmented cyclone countercurrent chemical washing tower and a method of using the same are proposed to solve the existing problems.

[0014] The present invention also discloses a method for using a high-efficiency segmented cyclone countercurrent chemical scrubber, which specifically comprises the following steps:

[0015] S1. The flue gas is transmitted to the interior of the first air inlet pipe through the second air inlet pipe. During the transmission process, the flue gas is filtered by the dust removal filter plate. After entering the first air inlet pipe, the flue gas enters the interior of the air guide bin, and the flue gas drives the dial plate inside the air guide bin to rotate. After passing through the air guide bin, the flue gas passes through the transfer pipe and the air distribution pipe sleeve and is distributed inside the washing tower body;

[0016] The rotation of the dial plate synchronously drives the driving roller to rotate, and the driving roller drives the air distribution pipe sleeve to rotate in a circle to distribute air;

[0017] S2. The dial plate drives the driving roller to rotate. At the same time, the driving roller rotates to drive the sprocket to rotate, and the sprocket and the chain drive the rotating column to rotate. The rotating column drives the pulley to rotate at the same time. The pulley forms a transmission match with the belt synchronously, and drives the vertical rod to rotate synchronously through the transmission match. The rotation of the vertical rod drives the main bevel gear to rotate. The main bevel gear is synchronously meshed with the slave bevel gear. The meshing of the main bevel gear and the slave bevel gear causes the reciprocating screw to rotate.

[0018] The reciprocating screw rotates, and the threaded sleeve on its surface will move back and forth. The threaded sleeve moves forward and synchronously drives the push plate to move. As the push plate moves forward, the push plate will gradually approach the front top plate and push the front top plate to move. The front top plate synchronously drives the dust filter plate to move, prompting the dust filter plate to switch the filter surface. While the threaded sleeve drives the push plate to move, the threaded sleeve will also synchronously drive the tooth plate to move. The movement of the tooth plate will mesh with the gear. The meshing of the gear drives the rotating shaft and the brush roller sleeve to rotate. The brush roller sleeve rotates synchronously to remove dust from the filter surface of the dust filter plate during its movement.

[0019] S3. During the movement of the dust filter plate, the dust filter plate will also synchronously drive the extrusion baffle to move. The movement of the extrusion baffle gradually squeezes the ball. The extrusion of the ball will drive the sealing plate to move to the left. The sealing plate will move to the left and will be out of the closed cooperation with the spray hole. At this time, the flue gas entering the first air inlet pipe from the second air inlet pipe, part of which enters the reducer, and is blown out from the spray hole at a high speed through the reducer and the air storage box. The blown filtered flue gas will clear the filter holes of the continuously moving position of the dust filter plate. After the dust is cleaned, the dust accumulates at the bottom of the inner cavity of the processing box, and the excess gas is re-integrated into the second air inlet pipe through the reflux pipe and the one-way valve.

[0020] Preferably, one side of the processing box in S3 is hinged with a box door via a hinge.

[0021] The present invention provides a high-efficiency segmented cyclone countercurrent chemical scrubber and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The high-efficiency segmented cyclone countercurrent chemical scrubber and its use method, by adding a self-driven air distribution mechanism, a filter air pretreatment mechanism and a deep cleaning mechanism inside and outside the scrubber body, enables the scrubber body to self-drive and evenly distribute the flue gas during the gas scrubbing process through the synchronous coordination of the self-driven air distribution mechanism, the filter air pretreatment mechanism and the deep cleaning mechanism, thereby achieving the purpose of further reducing energy consumption, and simultaneously pre-treating the intake air for dust to reduce the deposition of solid impurities in the tower bottom liquid level inside the scrubber body, and simultaneously continuously and deeply clean the dust removal filter plate inside the filter air pretreatment mechanism to ensure that it maintains a smooth filter air state.

[0023] (2) The high-efficiency segmented cyclone countercurrent chemical scrubber and its use method provide a return pipe between the treatment box and the second air inlet pipe, so that the purge gas inside the second air inlet pipe can be easily separated from the gas and ash and the gas can be unidirectionally recovered to the inside of the second air inlet pipe.

[0024] (3) The high-efficiency segmented cyclone countercurrent chemical scrubber and its use method are characterized in that a push plate is provided at the bottom of the threaded sleeve, and top plates used in conjunction with the push plate are provided on the front and rear sides of the top of the dust filter plate, so that the switching of the filter surface of the dust filter plate can be achieved intermittently through the cooperation of the top plate and the push plate.

[0025] (4) The high-efficiency segmented cyclone countercurrent chemical scrubber and its use method are characterized by connecting a reducer on one side of the gas storage box so that the reducer can be designed with a variable diameter to enhance the wind strength of the flue gas inside the reducer.

[0054] The present invention also discloses a method for using a high-efficiency segmented cyclone countercurrent chemical scrubber, which specifically comprises the following steps:

[0055] S1. The smoke is transmitted to the interior of the first air inlet pipe 3 through the second air inlet pipe 502. During the transmission process, the smoke is filtered by the dust removal filter plate 503. After entering the first air inlet pipe 3, the smoke enters the interior of the air guide bin 2, and the smoke drives the transfer plate 402 inside the air guide bin 2 to rotate. After passing through the air guide bin 2, the smoke passes through the transfer pipe 404 and the air distribution pipe sleeve 403 and is distributed inside the washing tower body 1;

[0056] The rotation of the dial plate 402 synchronously drives the driving roller 401 to rotate, and the driving roller 401 rotates to drive the air distribution pipe sleeve 403 to perform circular rotation to distribute air;

[0057] S2, the dial plate 402 drives the driving roller 401 to rotate.

The reciprocating screw 504 is driven to rotate through the meshing of the main bevel gear 5137 and the slave bevel gear 5138.

[0058] The reciprocating screw 504 rotates the threaded sleeve 505 on its surface to move back and forth. The threaded sleeve 505 moves forward and synchronously drives the push plate 507 to move. As the push plate 507 moves forward, the push plate 507 gradually approaches the front top plate 506 and pushes the front top plate 506 to move. The front top plate 506 synchronously drives the dust filter plate 503 to move, prompting the dust filter plate 503 to switch the filtering surface. While the threaded sleeve 505 drives the push plate 507 to move, the threaded sleeve 505 also synchronously drives the tooth plate 511 to move. The movement of the tooth plate 511 will mesh with the gear 510. The meshing of the gear 510 drives the rotating shaft 508 and the brush roller sleeve 509 to rotate. The brush roller sleeve 509 rotates synchronously to remove dust from the filtering surface of the dust filter plate 503 during its movement.

[0059] S3. During the movement of the dust filter plate 503, the dust filter plate 503 will also synchronously drive the extrusion baffle 606 to move. The movement of the extrusion baffle 606 gradually squeezes the ball 605. The extrusion of the ball 605 will drive the sealing plate 604 to move to the left. The sealing plate 604 moves to the left and will break away from the closed cooperation with the nozzle 603. At this time, the flue gas entering the first air inlet pipe 3 from the second air inlet pipe 502, its local flue gas enters the reducer 601, and is blown out from the nozzle 603 at a high speed through the reducer 601 and the gas storage box 602. The blown filtered flue gas will clear the filter holes of the dust filter plate 503 that are constantly moving. After the dust is cleaned, the dust accumulates at the bottom of the inner cavity of the processing box 501, and the excess gas is re-returned to the second air inlet pipe 502 through the reflux pipe 14 and the one-way valve, where one side of the processing box 501 is hinged with a box door by a hinge.

3. A method for using the high-efficiency segmented cyclone countercurrent chemical scrubber as claimed in claim 1, characterized in that: The following steps are involved: S1, the smoke is transmitted to the interior of the first air inlet pipe (3) through the second air inlet pipe (502), and is filtered by the dust removal filter plate (503) during the transmission process. After the smoke enters the first air inlet pipe (3), it enters the interior of the air guide bin (2), and the smoke drives the dial plate (402) inside the air guide bin (2) to rotate. After the smoke passes through the air guide bin (2), it passes through the transfer pipe (404) and the air distribution pipe sleeve (403) and is distributed inside the washing tower body (1); The rotating plate (402) rotates synchronously to drive the driving roller (401) to rotate, and the driving roller (401) rotates to drive the air distribution pipe sleeve (403) to perform circular rotation to distribute air; S2, the dial plate (402) drives the driving roller (401) to rotate. At the same time, the driving roller (401) rotates to drive the sprocket (5132) to rotate, and the rotation column (5131) is driven to rotate through the transmission cooperation of the sprocket (5132) and the chain (5133). The rotation of the rotating column (5131) drives the pulley (5135) to rotate at the same time. The pulley (5135) forms a transmission cooperation with the belt (5136) synchronously, and drives the vertical rod (5134) to rotate synchronously through the transmission cooperation. The rotation of the vertical rod (5134) drives the main bevel gear (5137) to rotate. The main bevel gear (5137) is synchronously meshed with the slave bevel gear (5138). The reciprocating screw (504) is driven to rotate through the meshing of the main bevel gear (5137) and the slave bevel gear (5138). The reciprocating screw (504) rotates the threaded sleeve (505) on its surface to move back and forth. The threaded sleeve (505) moves forward and synchronously drives the push plate (507) to move. As the push plate (507) moves forward, the push plate (507) gradually approaches the front top plate (506) and pushes the front top plate (506) to move. The front top plate (506) synchronously drives the dust filter plate (503) to move, prompting the dust filter plate (503) to switch the filter surface. When the threaded sleeve (505) drives the push plate (507) to move, the threaded sleeve (505) also synchronously drives the tooth plate (511) to move. The tooth plate (511) moves and meshes with the gear (510). The meshing of the gear (510) drives the rotating shaft (508) and the brush roller sleeve (509) to rotate. The brush roller sleeve (509) rotates synchronously to remove dust from the filter surface of the dust filter plate (503) during its movement. S3. During the movement of the dust filter plate (503), the dust filter plate (503) will also synchronously drive the extrusion bar (606) to move. The movement of the extrusion bar (606) gradually squeezes the ball (605). The ball (605) is squeezed and drives the sealing plate (604) to move leftward. The sealing plate (604) moves leftward and separates from the closed fit with the spray hole (603). At this time, the second air inlet pipe (502) enters the first air inlet pipe (3). The smoke of part of the smoke enters the reducer (601) and is blown out from the nozzle (603) at a high speed through the reducer (601) and the gas storage box (602). The blown filtered smoke will clean the filter holes of the dust removal filter plate (503) which are constantly moving. After the dust is cleaned, the dust accumulates at the bottom of the inner cavity of the processing box (501), and the excess gas is re-integrated into the second air inlet pipe (502) through the return pipe (14) and the one-way valve.

4. The method for using the high-efficiency segmented cyclone countercurrent chemical scrubber according to claim 3 is characterized in that: One side of the processing box (501) in S3 is hinged with a box door via a hinge.
