Description

Technical Field

[0001] The present invention belongs to the field of industrial waste gas treatment, and specifically relates to an industrial waste gas treatment device for preventing air pollution and its operation method. Background Art

[0002] Air pollution refers to the phenomenon that the concentration of pollutants in the atmosphere reaches a harmful level, thereby destroying the ecological system and the conditions for the normal survival and development of humans, and causing harm to people and objects. Its causes include natural factors (such as volcanic eruptions, forest disasters, rock weathering, etc.) and human factors (such as industrial waste gas, fuel, automobile exhaust, etc.). The most common one is the emission of industrial waste gas. Industrial waste gas includes sulfur dioxide, hydrogen sulfide, ammonia, etc. When treating sulfur dioxide in the waste gas, most factories will adopt the method of spraying limestone slurry, so that sulfur dioxide reacts with limestone slurry to form calcium sulfite, and then is oxidized to calcium sulfate (gypsum).

[0003] In the existing technology, when spraying waste gas containing sulfur dioxide, it is not convenient to make the limestone slurry fully contact with the waste gas. The waste gas is extremely easy to pass through the spraying range of the limestone slurry and does not have enough time to react with the limestone slurry, which affects the treatment effect of sulfur dioxide. Moreover, after the limestone slurry reacts with the waste gas containing sulfur dioxide, gypsum will be produced. The existing technology is not convenient to separate the limestone slurry from the gypsum while purifying sulfur dioxide. The mixture of the limestone slurry and gypsum will affect the use of the limestone slurry and cause waste of resources.

[0004] Therefore, the present invention provides an industrial waste gas treatment device for preventing air pollution and its operation method. Summary of the Invention

[0015] An operation method of an industrial waste gas treatment device for preventing air pollution, which is applicable to the above-mentioned industrial waste gas treatment device for preventing air pollution. The steps of the method are as follows:

[0016] S1: Place the housing in the factory. Fill the second liquid accumulation cavity with limestone slurry. Start the air pump and draw the gas in the factory into the housing along the air inlet groove.

[0017] S2: Start the four spray heads to form a closed loop to spray limestone slurry on the upward flowing gas. Use the electric telescopic rod to control the four spray heads to swing to increase the spraying range.

[0018] S3: Start the motor to drive the reciprocating lead screw to rotate counterclockwise, so that the receiving plate generates a centrifugal force to separate the gypsum from the limestone slurry. When cleaning the gypsum on the piston plate, start the motor to drive the reciprocating lead screw to rotate clockwise to move the piston plate up and down.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For an industrial waste gas treatment device for preventing air pollution and its operation method according to the present invention, limestone slurry is sprayed on the upward flowing gas through four nozzles to form a closed loop, so that sulfur dioxide in the gas reacts with the limestone slurry. The sprayed limestone slurry accumulates in the first liquid accumulation cavity. The gas enters the housing along the air inlet groove and then flows downward along the arc surface at the bottom of the guiding ring. Under the guiding of the guiding ring, the gas impacts on the limestone slurry in the first liquid accumulation cavity, so that sulfur dioxide in the gas reacts with the limestone slurry.

[0021] 2. For an industrial waste gas treatment device for preventing air pollution and its operation method according to the present invention, the motor is used to control the rotation of the receiving plate to filter the limestone slurry mixed with gypsum, so as to separate the gypsum from the limestone slurry. When the receiving plate rotates, it drives several first flow disturbing plates to rotate. Under the action of the inclined surface at the bottom of the first flow disturbing plate, part of the gas is pushed to impact downward, so that the gas contacts the limestone slurry flowing along the flow blocking ring, thereby prolonging the reaction time between the gas and the limestone slurry.

[0022] 3. For an industrial waste gas treatment device for preventing air pollution and its operation method according to the present invention, the gypsum generated by the reaction of the limestone slurry in the first liquid accumulation cavity accumulates on the piston plate. It is necessary to clean the gypsum on the piston plate regularly. The motor is used to control the reciprocating screw rod to rotate clockwise, so that the piston plate moves up and down reciprocally. When the piston plate moves upward to be flush with the liquid discharge groove, the gypsum on the piston plate slides down along the inclined surface of the piston plate. When the motor controls the reciprocating screw rod to rotate counterclockwise, the limestone slurry in the first liquid accumulation cavity forms ripples and water flowers through the rotation of the second flow disturbing plate, thereby increasing the contact area between the gas and the limestone slurry.

[0023] 4. For an industrial waste gas treatment device for preventing air pollution and its operation method according to the present invention, the limestone slurry falling at the communication groove is filtered by the filter plate to separate the limestone slurry from the gypsum. Through the cooperation of the convex block and the top block, the filter plate is continuously vibrated, effectively preventing the filter plate from being blocked by gypsum.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] Such as Figures 1 to 9As shown in the figure, the present invention provides a technical solution, an industrial waste gas treatment device for preventing air pollution, which includes a housing 1. A gas pump 12 is fixedly connected to the top of the housing 1. The output end of the gas pump 12 is connected to an air extraction pipe 13. One end of the air extraction pipe 13 extends into the interior of the housing 1. A number of air inlet grooves 14 are equidistantly arranged on the outer wall of the housing 1. A guide plate 2 is fixedly connected to the inner wall of the housing 1. The guide plate 2 is arranged in a ring shape and its bottom is provided with an upwardly inclined slope. Four installation grooves 3 are equidistantly arranged on the inner wall of the guide plate 2. Four rotating shafts 4 are rotatably connected to the top of the guide plate 2 at equal intervals. The bottoms of the four rotating shafts 4 respectively extend into the interiors of the four installation grooves 3. Nozzles 5 are fixedly connected to the bottoms of the four rotating shafts 4. A second liquid accumulation cavity 34 is formed inside the housing 1. A water pump 15 is fixedly connected to the bottom of the housing 1. The output end of the water pump 15 is connected to a water extraction pipe 16. The bottom of the water extraction pipe 16 is connected to four shunt pipes 17. The four shunt pipes 17 are respectively connected to the four nozzles 5. A driving assembly is arranged on the top of the guide plate 2.

[0037] Through the above technical solution, the housing 1 is placed in the factory. Limestone slurry is filled into the second liquid accumulation cavity 34. The gas pump 12 is started to draw the gas in the factory into the housing 1 along the air inlet grooves 14 (switch valves are provided on the air inlet grooves 14). The gas entering the housing 1 flows upward along the slope at the bottom of the guide plate 2, and through the arranged guide plate 2, the flow range of the gas in the housing 1 is reduced, making the gas more concentrated, which is convenient for the subsequent sprayed limestone slurry to fully contact the gas. The water pump 15 is started to pump the limestone slurry along the water extraction pipe 16 and the four shunt pipes 17 to the four nozzles 5. The four nozzles 5 form a closed loop to spray the limestone slurry on the upward flowing gas, so that the sulfur dioxide in the gas reacts with the limestone slurry. The four nozzles 5 are controlled to rotate by the driving assembly to increase the spraying range of the limestone slurry and improve the contact area between the sulfur dioxide and the limestone slurry. The purified air is discharged from the housing 1 through the air extraction pipe 13.

[0038] Scenario 1: The housing 1 is placed in a unmanned factory. After the industrial waste gas in the unmanned factory is treated by this device, the treated gas is then discharged along the exhaust pipe of the unmanned factory.

[0039] Scenario 2: A hose is connected to the factory exhaust pipe and connected to the air inlet groove 14 of this device. The industrial waste gas extracted from the factory enters this device along the exhaust pipe and the hose, and the industrial waste gas is treated by this device.

[0040] Specifically, the driving assembly includes a toothed ring 7. The toothed ring 7 is arranged on the top of the guide plate 2 and is rotatably connected to the guide plate 2. Gears 6 are fixedly connected to the tops of the four rotating shafts 4. The four gears 6 are all meshed with the toothed ring 7. An electric telescopic rod 8 is fixedly connected to the top of the guide plate 2. A rack 9 is fixedly connected to the output end of the electric telescopic rod 8. The rack 9 is meshed with the toothed ring 7.

[0041] Through the above technical solution, the electric telescopic rod 8 controls the rack 9 to reciprocate left and right, driving the toothed ring 7 to rotate reciprocally forward and backward. While the toothed ring 7 rotates, it drives the four gears 6 to rotate simultaneously, enabling the four rotating shafts 4 to rotate simultaneously, and driving the four nozzles 5 to rotate simultaneously, thereby improving the spraying range of the limestone slurry.

[0042] Specifically, a first liquid accumulation cavity 33 is formed at the bottom of the inner wall of the housing 1. The first liquid accumulation cavity 33 is located above the second liquid accumulation cavity 34. A liquid discharge groove 44 is formed on the inner wall of the first liquid accumulation cavity 33. A communication groove 45 is formed between the liquid discharge groove 44 and the second liquid accumulation cavity 34. A guiding ring 24 is fixedly connected to the inner wall of the housing 1 and above the first liquid accumulation cavity 33. The bottom of the guiding ring 24 is provided with an arc surface. A plurality of flow blocking rings 25 are fixedly connected to the top of the guiding ring 24 at equal intervals. The top of the flow blocking ring 25 is provided with an inclined surface. The diameters of the plurality of flow blocking rings 25 gradually decrease from outside to inside.

[0043] Through the above technical solution, the sprayed limestone slurry falls on the top of the guiding ring 24 and slides down along the guiding ring 24. Through the plurality of flow blocking rings 25 provided, the sliding speed of the limestone slurry is delayed, and a drop is formed at the end of the flow blocking ring 25, enabling the limestone slurry to form a water curtain, increasing the coverage area of the limestone slurry. The limestone slurry passing through the guiding ring 24 falls into the first liquid accumulation cavity 33. The gas enters the housing 1 along the air inlet groove 14 and flows downward along the arc surface at the bottom of the guiding ring 24. Under the guiding of the guiding ring 24, the gas impacts on the limestone slurry in the first liquid accumulation cavity 33, enabling the sulfur dioxide in the gas to react with the limestone slurry. The gas passing through the guiding ring 24 continues to flow upward. When the limestone slurry in the first liquid accumulation cavity 33 is flush with the liquid discharge groove 44, the excess limestone slurry re-enters the second liquid accumulation cavity 34 along the liquid discharge groove 44 and the communication groove 45.

[0044] Specifically, a motor 18 is fixedly connected to the bottom of the housing 1. The output end of the motor 18 extends into the housing 1 and is fixedly connected to a reciprocating lead screw 19. The top of the reciprocating lead screw 19 is fixedly connected to a material accumulation plate 20. The material accumulation plate 20 is located above the guiding ring 24. A receiving plate 21 is fixedly connected to the top of the material accumulation plate 20. A pressing ring 22 is fixedly connected to the top of the receiving plate 21. The top of the pressing ring 22 is bent downward. A plurality of sieve holes 43 are formed at equal intervals on the outer wall of the pressing ring 22. A plurality of first flow disturbing plates 23 are fixedly connected to the bottom of the receiving plate 21 at equal intervals. The bottom of the first flow disturbing plate 23 is provided with symmetric inclined surfaces. A spiral top cover 42 is threadedly connected to the top of the housing 1.

[0045] Through the above technical solution, the limestone slurry falling by spraying lands on the receiving plate 21. The motor 18 is started to drive the material accumulating plate 20 and the receiving plate 21 to rotate. Through the arranged pressing ring 22, the limestone slurry in the receiving plate 21 is blocked to prevent the limestone slurry from being thrown out. Under the action of centrifugal force, it is convenient to throw out the limestone slurry along the sieve holes 43. The gypsum formed by the reaction of the limestone slurry and sulfur dioxide remains on the receiving plate 21. When the motor 18 is turned off, the gypsum slides down along the inclined surface at the top of the receiving plate 21 and accumulates in the material accumulating plate 20. By turning the spiral top cover 42 in a spiral manner, it is convenient to take out the gypsum in the material accumulating plate 20. When the limestone slurry is thrown out from the sieve holes 43, an annular water curtain is formed, which is convenient to react with the gas passing by here. While the receiving plate 21 rotates, it drives several first spoiler plates 23 to rotate. During the rotation of the first spoiler plates 23, the inclined surfaces of the first spoiler plates 23 exert a downward pressing effect on the gas flowing upward. Under the action of the inclined surface at the bottom of the first spoiler plates 23, part of the gas is pushed to impact downward, so that the gas contacts the limestone slurry flowing along the baffle ring 25, thereby prolonging the reaction time between the gas and the limestone slurry.

[0046] Specifically, a drainage groove 10 is formed inside the guide plate 2 and below the installation groove 3, and a plurality of water discharge grooves 11 are equidistantly formed at the bottom of the drainage groove 10.

[0047] Through the above technical solution, the limestone slurry sprayed by the nozzle 5 impacts on the other side of the inner wall of the guide plate 2 and slides down along the inner wall of the guide plate 2. When the limestone slurry slides to the drainage groove 10, the limestone slurry enters the drainage groove 10 and continues to slide down. When passing through a plurality of water discharge grooves 11, it falls, thereby forming multiple water curtains of the limestone slurry to react with the gas flowing upward, thereby prolonging the reaction time between the gas and the limestone slurry.

[0048] Specifically, a slider 26 is connected to the outer wall of the reciprocating lead screw 19 through a lead screw nut pair. A piston plate 27 is fixedly connected to the outer wall of the slider 26. The reciprocating lead screw 19 penetrates through the piston plate 27. The piston plate 27 fits the inner wall of the first liquid accumulation cavity 33. An adjusting assembly is arranged at the bottom of the piston plate 27, and the top of the piston plate 27 is set as an annular inclined surface.

[0049] Through the above technical solution, the gypsum generated by reacting with the limestone slurry in the first liquid accumulation cavity 33 accumulates on the piston plate 27. It is necessary to clean the gypsum on the piston plate 27 regularly. Start the motor 18 to drive the reciprocating lead screw 19 to rotate counterclockwise. Under the action of the adjustment assembly, the slider 26 rotates counterclockwise, driving the piston plate 27 to rotate counterclockwise. When cleaning the gypsum on the piston plate 27, start the motor 18 to drive the reciprocating lead screw 19 to rotate clockwise. Under the action of the adjustment assembly, the slider 26 reciprocates up and down, driving the piston plate 27 to reciprocate up and down. When the piston plate 27 moves upward to be flush with the liquid discharge groove 44, the gypsum on the piston plate 27 slides down along the inclined surface of the piston plate 27 and passes through the liquid discharge groove 44 and the communication groove 45 into the second liquid accumulation cavity 34.

[0050] Specifically, the adjustment assembly includes a fixed ring 28. The fixed ring 28 is fixedly installed at the bottom of the piston plate 27. The fixed ring 28 fits against the inner wall of the first liquid accumulation cavity 33. Two limit blocks 29 are slidably connected equidistantly inside the fixed ring 28. One side of each of the two limit blocks 29 is provided with an inclined surface. Two first springs 30 are fixedly connected equidistantly inside the fixed ring 28. One end of each first spring 30 is fixedly connected to the limit block 29. A limit sliding groove 31 for cooperating with the limit block 29 is provided on the inner wall of the first liquid accumulation cavity 33.

[0051] Through the above technical solution, start the motor 18 to drive the reciprocating lead screw 19 to rotate counterclockwise, causing the slider 26 to rotate counterclockwise and driving the limit block 29 to rotate counterclockwise. When the limit block 29 rotates to the limit sliding groove 31, under the action of the first spring 30, the limit block 29 enters the limit sliding groove 31. As the reciprocating lead screw 19 continues to rotate, the inclined surface on one side of the limit block 29 abuts against the limit sliding groove 31. Under the extrusion of the limit sliding groove 31, the limit block 29 moves into the piston plate 27, compressing the first spring 30. Thus, when the reciprocating lead screw 19 rotates counterclockwise, it drives the slider 26 and the piston plate 27 to rotate counterclockwise. Start the motor 18 to drive the reciprocating lead screw 19 to rotate clockwise, causing the slider 26 to rotate clockwise and driving the limit block 29 to rotate clockwise. When the limit block 29 rotates to the limit sliding groove 31, under the action of the first spring 30, the limit block 29 enters the limit sliding groove 31. As the reciprocating lead screw 19 continues to rotate, the straight surface on one side of the limit block 29 abuts against the limit sliding groove 31 and cannot rotate. Thus, when the reciprocating lead screw 19 rotates clockwise, it drives the slider 26 and the piston plate 27 to reciprocate up and down.

[0052] Specifically, a plurality of second spoiler plates 32 are fixedly connected equidistantly at the top of the piston plate 27. The top of the second spoiler plate 32 is provided with symmetric inclined surfaces.

[0053] Through the above technical solution, when the piston plate 27 rotates, it drives several second spoiler plates 32 to rotate. The rotation of the second spoiler plates 32 causes the limestone slurry in the first liquid accumulation cavity 33 to form ripples and water splashes, thereby increasing the contact area between the gas and the limestone slurry and improving the purification effect on sulfur dioxide.

[0054] Specifically, four sliding shafts 35 are symmetrically and fixedly connected to the inner wall of the second liquid accumulation cavity 34. A sliding plate 36 is slidably connected to the outer walls of the four sliding shafts 35. A filter plate 38 is fixedly connected to the inner wall of the sliding plate 36. The longitudinal section of the filter plate 38 is set as an inverted isosceles trapezoid. A second spring 37 is sleeved on the outer wall of the sliding shaft 35. The bottom of the second spring 37 is fixedly connected to the housing 1, and the top of the second spring 37 is fixedly connected to the sliding plate 36. A fixing plate 39 is fixedly connected to the outer wall of the reciprocating lead screw 19 and above the sliding plate 36. Two top blocks 41 are symmetrically and fixedly connected to the bottom of the fixing plate 39. The bottoms of the two top blocks 41 are both arc-shaped. Two convex blocks 40 are symmetrically and fixedly connected to the top of the sliding plate 36. The tops of the two convex blocks 40 are both set as symmetrical inclined surfaces. The convex blocks 40 are used in cooperation with the top blocks 41. A sealing door is rotatably connected to the outer wall of the housing 1.

[0055] Through the above technical solution, the limestone slurry falling from the communication groove 45 lands on the filter plate 38. The limestone slurry is filtered by the filter plate 38, thereby separating the limestone slurry from the gypsum formed by the reaction. The filtered limestone slurry passes through the filter plate 38 and accumulates at the bottom of the second liquid accumulation cavity 34, and the gypsum remains on the top of the filter plate 38. The gypsum on the filter plate 38 can be taken out by opening the sealing door. When the reciprocating lead screw 19 rotates, it drives the fixing plate 39 to rotate, causing the top blocks 41 to rotate. When the top blocks 41 rotate to a position close to the convex blocks 40, under the extrusion of the top blocks 41, the inclined surfaces at the tops of the convex blocks 40 are pressed tightly, causing the convex blocks 40 to move downward, driving the sliding plate 36 and the filter plate 38 to move downward. When the sliding plate 36 moves downward, it compresses the second spring 37. As the top blocks 41 continue to rotate, when the top blocks 41 disengage from the convex blocks 40, under the action of the second spring 37, the sliding plate 36 and the filter plate 38 move upward and vibrate. Thus, reciprocatingly, the reciprocating lead screw 19 rotates and drives the filter plate 38 to continuously vibrate, effectively preventing the filter plate 38 from being blocked by gypsum.

[0056] An operation method of an industrial waste gas treatment device for preventing air pollution, which is applicable to the above-mentioned industrial waste gas treatment device for preventing air pollution. The steps of the method are as follows:

[0057] S1: Place the housing 1 in the factory, fill the second liquid accumulation cavity 34 with limestone slurry, start the air pump 12, and draw the gas in the factory into the housing 1 along the air inlet groove 14;

[0058] S2: Start the four spray nozzles 5 to form a closed loop to spray limestone slurry on the upward flowing gas, and use the electric telescopic rod 8 to control the swing of the four spray nozzles 5 to increase the spraying range;

[0059] S3: Start the motor 18 to drive the reciprocating lead screw 19 to rotate counterclockwise, so that the receiving plate 21 generates centrifugal force to separate the gypsum from the limestone slurry. When cleaning the gypsum on the piston plate 27, start the motor 18 to drive the reciprocating lead screw 19 to rotate clockwise to move the piston plate 27 up and down.

[0060] During use, place the housing 1 in the factory. Fill the interior of the second liquid accumulation chamber 34 with limestone slurry. Start the air pump 12 to draw the gas in the factory along the air inlet groove 14 into the housing 1. The gas entering the housing 1 flows upward along the inclined surface at the bottom of the guide plate 2 and passes through the provided guide plate 2 to narrow the flow range of the gas in the housing 1, making the gas more concentrated, facilitating the subsequent full contact between the sprayed limestone slurry and the gas. Start the water pump 15 to pump the limestone slurry along the water extraction pipe 16 and the four shunt pipes 17 to the four nozzles 5. The limestone slurry is sprayed on the upward flowing gas through the four nozzles 5 to form a closed loop, causing the sulfur dioxide in the gas to react with the limestone slurry. Control the rack 9 to reciprocate left and right by the electric telescopic rod 8, driving the toothed ring 7 to rotate reciprocally forward and backward. While the toothed ring 7 rotates, it drives the four gears 6 to rotate simultaneously, causing the four rotating shafts 4 to rotate simultaneously, driving the four nozzles 5 to rotate simultaneously, thereby increasing the spraying range of the limestone slurry. The limestone slurry sprayed by the nozzles 5 impacts the other side of the inner wall of the guide plate 2 and slides downward along the inner wall of the guide plate 2. When the limestone slurry slides to the drainage groove 10, the limestone slurry enters the drainage groove 10 and continues to slide. When passing through several water discharge grooves 11, it drops, thereby forming multiple water curtains of the limestone slurry to react with the upward flowing gas, thus prolonging the reaction time between the gas and the limestone slurry. The sprayed and dropped limestone slurry lands on the receiving plate 21. Start the motor 18 to drive the material accumulation plate 20 and the receiving plate 21 to rotate. Through the provided pressing ring 22, the limestone slurry in the receiving plate 21 is blocked to prevent the limestone slurry from being thrown out. Under the action of centrifugal force, it is convenient to throw out the limestone slurry along the sieve holes 43. The gypsum formed by the reaction of the limestone slurry and sulfur dioxide remains on the receiving plate 21. The limestone slurry at the sieve holes 43 lands on the top of the guiding ring 24 and slides downward along the guiding ring 24. Through the provided several flow blocking rings 25, the sliding speed of the limestone slurry is delayed, and a drop is formed at the end of the flow blocking ring 25, causing the limestone slurry to form a water curtain and increasing the coverage area of the limestone slurry. The limestone slurry passing through the guiding ring 24 falls into the first liquid accumulation chamber 33. The gas enters the housing 1 along the air inlet groove 14 and then flows downward along the arc surface at the bottom of the guiding ring 24. Under the guiding of the guiding ring 24, the gas impacts on the limestone slurry in the first liquid accumulation chamber 33, causing the sulfur dioxide in the gas to react with the limestone slurry. The gas passing through the guiding ring 24 continues to flow upward. When the limestone slurry in the first liquid accumulation chamber 33 is flush with the liquid discharge groove 44, the excess limestone slurry re-enters the second liquid accumulation chamber 34 along the liquid discharge groove 44 and the connecting groove 45. When the motor 18 is turned off, the gypsum slides down along the inclined surface at the top of the receiving plate 21 and accumulates in the material accumulation plate 20. Open the spiral top cover 42 through the spiral to facilitate the removal of the gypsum in the material accumulation plate 20. When the limestone slurry is thrown out from the sieve holes 43, it forms an annular water curtain, facilitating the reaction with the gas passing by here. While the receiving plate 21 rotates, it drives several first flow disturbing plates 23 to rotate.During the rotation of the first spoiler 23, its inclined surface exerts a downward pressing force on the upward flowing gas. Under the action of the inclined surface at the bottom of the first spoiler 23, part of the gas is pushed downward to impact, causing the gas to contact the limestone slurry flowing along the baffle ring 25. Thus, the reaction time between the gas and the limestone slurry is extended. The gypsum generated by the reaction with the limestone slurry in the first liquid accumulation cavity 33 accumulates on the piston plate 27, and it is necessary to clean the gypsum on the piston plate 27 regularly. When cleaning the gypsum on the piston plate 27, the motor 18 is started to drive the reciprocating lead screw 19 to rotate clockwise, causing the slider 26 to rotate clockwise, driving the limit block 29 to rotate clockwise. When the limit block 29 rotates to the limit chute 31, under the action of the first spring 30, the limit block 29 enters the limit chute 31. As the reciprocating lead screw 19 continues to rotate, the straight surface on one side of the limit block 29 abuts against the limit chute 31 and cannot rotate. Thus, when the reciprocating lead screw 19 rotates clockwise, it drives the slider 26 and the piston plate 27 to reciprocate up and down. When the piston plate 27 moves upward to be flush with the drain groove 44, the gypsum on the piston plate 27 slides down along the inclined surface of the piston plate 27 and passes through the drain groove 44 and the communication groove 45 into the second liquid accumulation cavity 34. After the gypsum on the piston plate 27 is cleaned, the motor 18 is started to drive the reciprocating lead screw 19 to rotate counterclockwise. Under the action of the adjustment assembly, the slider 26 rotates counterclockwise, driving the limit block 29 to rotate counterclockwise. When the limit block 29 rotates to the limit chute 31, under the action of the first spring 30, the limit block 29 enters the limit chute 31. As the reciprocating lead screw 19 continues to rotate, the inclined surface on one side of the limit block 29 abuts against the limit chute 31. Under the extrusion of the limit chute 31, the limit block 29 moves into the piston plate 27, compressing the first spring 30. Thus, when the reciprocating lead screw 19 rotates counterclockwise, it drives the slider 26 and the piston plate 27 to rotate counterclockwise. While the piston plate 27 rotates, it drives several second spoilers 32 to rotate. By the rotation of the second spoilers 32, the limestone slurry in the first liquid accumulation cavity 33 forms ripples and water splashes, thereby increasing the contact area between the gas and the limestone slurry and enhancing the purification effect on sulfur dioxide. The limestone slurry falling from the communication groove 45 lands on the filter plate 38. The limestone slurry is filtered by the filter plate 38, thereby separating the limestone slurry from the formed gypsum. The filtered limestone slurry passes through the filter plate 38 and accumulates at the bottom of the second liquid accumulation cavity 34, and the gypsum remains on the top of the filter plate 38. The gypsum on the filter plate 38 can be taken out by opening the sealing door. While the reciprocating lead screw 19 rotates, it drives the fixed plate 39 to rotate, causing the top block 41 to rotate. When the top block 41 rotates to the position where it abuts against the convex block 40, under the extrusion of the top block 41, it abuts against the inclined surface at the top of the convex block 40, causing the convex block 40 to move downward, driving the slide plate 36 and the filter plate 38 to move downward. While the slide plate 36 moves downward, it compresses the second spring 37. As the top block 41 continues to rotate, when the top block 41 disengages from the convex block 40, under the action of the second spring 37,Move the skateboard 36 and the filter plate 38 upward and vibrate them. Thus, reciprocate. While the reciprocating lead screw 19 rotates, it drives the filter plate 38 to vibrate continuously, effectively avoiding the blockage of the filter plate 38 by gypsum.
