Description

Technical Field

[0002] Air pollution refers to the phenomenon that the concentration of pollutants in the atmosphere reaches a harmful level, destroying the ecosystem and the conditions for normal human survival and development, 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 and nuclear explosions, etc.), especially the latter. The most common is the emission of industrial waste gas, which includes sulfur dioxide, hydrogen sulfide, ammonia, etc. When treating sulfur dioxide in the waste gas, most factories will use the method of spraying limestone slurry to make sulfur dioxide react with limestone slurry to form calcium sulfite, which is then oxidized into calcium sulfate (gypsum).

The waste gas can easily pass through the spraying range of the limestone slurry, and there is not enough time to react with the limestone slurry, which affects the treatment effect of sulfur dioxide. In addition, the limestone slurry will produce gypsum after reacting with the waste gas containing sulfur dioxide. The existing technology is not convenient for separating the limestone slurry from the gypsum while purifying sulfur dioxide. The mixing of limestone slurry and gypsum will affect the use of limestone slurry, resulting in a waste of resources.

[0004] To this end, the present invention provides an industrial waste gas treatment device for preventing air pollution and an operating method thereof. Summary of the invention

[0024] Through the above technical scheme, the shell 1 is placed in the factory, limestone slurry is loaded into the second liquid accumulation chamber 34, the air pump 12 is started, and the gas in the factory is pumped into the shell 1 along the air inlet groove 14 (the air inlet groove 14 is provided with a switch valve), and the gas after entering the shell 1 flows upward along the inclined surface of the bottom of the guide plate 2, and through the provided guide plate 2, the circulation range of the gas in the shell 1 is reduced, so that the gas is more concentrated, which is convenient for the limestone slurry sprayed subsequently to fully contact with the gas, and the water pump 15 is started to pump the limestone slurry along the water pumping pipe 16 and the four diverter pipes 17 to the four nozzles 5, and a closed loop is formed by the four nozzles 5 to spray the limestone slurry on the gas flowing upward, so that the sulfur dioxide in the gas reacts with the limestone slurry, and the four nozzles 5 are controlled to rotate by the driving component to increase the spraying range of the limestone slurry and increase the contact area between the sulfur dioxide and the limestone slurry, and the purified air is discharged from the shell 1 from the air pumping pipe 13; Scenario 1: The housing 1 is placed in an unmanned factory, and the industrial waste gas in the unmanned factory is treated by the device, and then the treated gas is discharged along the exhaust pipe of the unmanned factory; Scenario 2: A hose is connected to the exhaust pipe of the factory and connected to the air inlet slot 14 of the device. The industrial waste gas extracted from the factory enters the device along the exhaust pipe and the hose, and the industrial waste gas is treated by the device.

[0025] Specifically, the driving assembly includes a gear ring 7, which is arranged on the top of the guide plate 2 and is rotatably connected to the guide plate 2. The tops of the four rotating shafts 4 are fixedly connected with gears 6, and the four gears 6 are meshingly connected to the gear ring 7. The top of the guide plate 2 is fixedly connected with an electric telescopic rod 8, and the output end of the electric telescopic rod 8 is fixedly connected with a rack 9, which is meshingly connected to the gear ring 7.

[0026] Through the above technical solution, the rack 9 is controlled to move back and forth left and right through the electric telescopic rod 8, driving the gear ring 7 to rotate back and forth. When the gear ring 7 rotates, it drives the four gears 6 to rotate at the same time, so that the four rotating shafts 4 rotate at the same time, driving the four nozzles 5 to rotate at the same time, thereby increasing the spraying range of the limestone slurry.

[0027] Specifically, a first liquid accumulation chamber 33 is provided at the bottom of the inner wall of the shell 1, and the first liquid accumulation chamber 33 is located above the second liquid accumulation chamber 34. A drainage groove 44 is provided on the inner wall of the first liquid accumulation chamber 33, and a connecting groove 45 is provided between the drainage groove 44 and the second liquid accumulation chamber 34. A guide ring 24 is fixedly connected to the inner wall of the shell 1 and located above the first liquid accumulation chamber 33, and an arc surface is provided at the bottom of the guide ring 24. A plurality of flow-blocking rings 25 are fixedly connected to the top of the guide ring 24 at equal intervals, and the top of the flow-blocking ring 25 is provided as an inclined surface, and the diameters of the plurality of flow-blocking rings 25 gradually decrease from the outside to the inside.

[0028] Through the above technical scheme, the sprayed limestone slurry falls on the top of the guide ring 24 and slides downward along the guide ring 24. The sliding speed of the limestone slurry is slowed down by the set several baffle rings 25, and a drop is formed at the end of the baffle ring 25, so that the limestone slurry forms a water curtain, increasing the coverage area of ​​the limestone slurry. The limestone slurry passing through the guide ring 24 falls into the first liquid accumulation chamber 33. After the gas enters the shell 1 along the air inlet groove 14, it flows downward along the arc surface at the bottom of the guide ring 24. Under the guidance of the guide ring 24, the gas collides with the limestone slurry in the first liquid accumulation chamber 33, so that the sulfur dioxide in the gas reacts with the limestone slurry. The gas passing through the guide ring 24 continues to flow upward. When the limestone slurry in the first liquid accumulation chamber 33 is flush with the drainage groove 44, the excess limestone slurry re-enters the second liquid accumulation chamber 34 along the drainage groove 44 and the connecting groove 45.

[0029] Specifically, the bottom of the shell 1 is fixedly connected to the motor 18, the output end of the motor 18 extends to the interior of the shell 1 and is fixedly connected to the reciprocating screw 19, the top of the reciprocating screw 19 is fixedly connected to the material accumulation plate 20, the material accumulation plate 20 is located above the guide ring 24, the top of the material accumulation plate 20 is fixedly connected to the receiving plate 21, the top of the receiving plate 21 is fixedly connected to the lower pressure ring 22, the top of the lower pressure ring 22 is bent downward, and the outer wall of the lower pressure ring 22 is equidistantly provided with a number of sieve holes 43, the bottom of the receiving plate 21 is equidistantly fixedly connected to a number of first spoilers 23, the bottom of the first spoiler 23 is set as a symmetrical inclined surface, and the top of the shell 1 is threadedly connected to a spiral top cover 42.

[0030] Through the above technical solution, the sprayed limestone slurry falls on the receiving plate 21, the motor 18 is started, and the material accumulation plate 20 and the receiving plate 21 are driven to rotate. The lower pressure ring 22 is provided to block the limestone slurry in the receiving plate 21 to prevent the limestone slurry from being thrown out. Under the action of centrifugal force, the limestone slurry is easily thrown out along the sieve mesh 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 accumulation plate 20. The spiral top cover 42 is opened to facilitate the removal of the gypsum in the accumulation plate 20. When the limestone slurry is thrown out from the sieve hole 43, an annular water curtain is formed, which is convenient for reacting with the gas passing there. The receiving plate 21 rotates while driving a plurality of first spoiler plates 23 to rotate. During the rotation process, the inclined surface of the first spoiler plates 23 exerts a downward pressure 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 downward to collide with the limestone slurry flowing along the baffle ring 25, thereby prolonging the reaction time of the gas and the limestone slurry.

[0031] Specifically, a drainage groove 10 is provided inside the guide plate 2 and below the mounting groove 3 , and a plurality of lower water grooves 11 are provided at equal intervals at the bottom of the drainage groove 10 .

[0032] Through the above technical solution, the limestone slurry sprayed from the nozzle 5 hits 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 down to the drainage groove 10, the limestone slurry enters the drainage groove 10 and continues to slide down, and falls down when passing through several lower water grooves 11, thereby forming a plurality of water curtains of the limestone slurry to react with the gas flowing upward, thereby extending the reaction time of the gas and the limestone slurry.

[0033] Specifically, the outer wall of the reciprocating screw 19 is connected to the slider 26 through a screw nut pair, the outer wall of the slider 26 is fixedly connected to the piston plate 27, the reciprocating screw 19 passes through the piston plate 27, the piston plate 27 fits the inner wall of the first liquid accumulation chamber 33, an adjustment component is provided at the bottom of the piston plate 27, and the top of the piston plate 27 is provided as an annular inclined surface.

[0034] Through the above technical solution, the gypsum produced by the reaction with the limestone slurry in the first liquid accumulation chamber 33 is accumulated on the piston plate 27. It is necessary to clean the gypsum on the piston plate 27 regularly, start the motor 18, drive the reciprocating screw 19 to rotate counterclockwise, and under the action of the adjusting component, make the slider 26 rotate counterclockwise, drive the piston plate 27 to rotate counterclockwise. When cleaning the gypsum on the piston plate 27, start the motor 18, drive the reciprocating screw 19 to rotate clockwise, and under the action of the adjusting component, make the slider 26 move back and forth up and down, drive the piston plate 27 to move back and forth up and down. When the piston plate 27 moves upward and is flush with the drainage groove 44, the gypsum on the piston plate 27 slides down along the inclined surface of the piston plate 27, and passes through the drainage groove 44 and the connecting groove 45 into the second liquid accumulation chamber 34.

[0035] Specifically, the adjustment component includes a fixed ring 28, which is fixedly installed on the bottom of the piston plate 27. The fixed ring 28 fits the inner wall of the first liquid accumulation chamber 33. Two limit blocks 29 are equidistantly slidably connected inside the fixed ring 28. One side of the two limit blocks 29 is set as an inclined surface. Two first springs 30 are equidistantly fixedly connected inside the fixed ring 28. One end of the first spring 30 is fixedly connected to the limit block 29. The inner wall of the first liquid accumulation chamber 33 is provided with a limit slide groove 31 used in conjunction with the limit block 29.

[0036] By the above technical solution, the motor 18 is started to drive the reciprocating screw 19 to rotate counterclockwise, so that the slider 26 rotates counterclockwise, and drives the limit block 29 to rotate counterclockwise. When the limit block 29 rotates to the limit slot 31, under the action of the first spring 30, the limit block 29 enters the limit slot 31. As the reciprocating screw 19 continues to rotate, the inclined surface on one side of the limit block 29 presses against the limit slot 31. Under the extrusion of the limit slot 31, the limit block 29 moves into the piston plate 27, compressing the first spring 30, thereby the reciprocating screw 19 rotates counterclockwise. When the reciprocating screw 19 moves, the slider 26 and the piston plate 27 rotate counterclockwise, the motor 18 is started, the reciprocating screw 19 rotates clockwise, the slider 26 rotates clockwise, and the limit block 29 rotates clockwise. When the limit block 29 rotates to the limit slot 31, under the action of the first spring 30, the limit block 29 enters the limit slot 31. As the reciprocating screw 19 continues to rotate, the straight surface of one side of the limit block 29 presses against the limit slot 31 and cannot rotate. Therefore, when the reciprocating screw 19 rotates clockwise, it drives the slider 26 and the piston plate 27 to move back and forth up and down.

[0037] Specifically, a plurality of second spoiler plates 32 are fixedly connected to the top of the piston plate 27 at equal intervals, and the tops of the second spoiler plates 32 are configured as symmetrical inclined surfaces.

[0038] Through the above technical solution, the piston plate 27 rotates while driving a plurality of second spoiler plates 32 to rotate. The rotation of the second spoiler plates 32 causes the limestone slurry in the first liquid accumulation chamber 33 to form ripples and splashes, thereby increasing the contact area between the gas and the limestone slurry and improving the purification effect of sulfur dioxide.

[0039] Specifically, the inner wall of the second liquid accumulation chamber 34 is symmetrically fixedly connected with four sliding shafts 35, the outer walls of the four sliding shafts 35 are slidably connected with a slide plate 36, the inner wall of the slide plate 36 is fixedly connected with a filter plate 38, the longitudinal cross-section of the filter plate 38 is set as an inverted isosceles trapezoid, the outer wall of the sliding shaft 35 is sleeved with a second spring 37, the bottom of the second spring 37 is fixedly connected to the shell 1, the top of the second spring 37 is fixedly connected to the slide plate 36, the outer wall of the reciprocating screw 19 and located above the slide plate 36 is fixedly connected with a fixed plate 39, the bottom of the fixed plate 39 is symmetrically fixedly connected with two top blocks 41, the bottom of the two top blocks 41 are both set to an arc shape, the top of the slide plate 36 is symmetrically fixedly connected with two protrusions 40, the tops of the two protrusions 40 are both set to symmetrical inclined surfaces, the protrusions 40 are used in conjunction with the top blocks 41, and the outer wall of the shell 1 is rotatably connected with a sealing door.

[0040] According to the above technical solution, the limestone slurry falling from the connecting groove 45 falls on the filter plate 38, and 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 is accumulated at the bottom of the second liquid accumulation chamber 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. The reciprocating screw 19 rotates while driving the fixed plate 39 to rotate, so that the top block 41 rotates. When the top block 41 rotates to close to the protrusion 40 When the top block 41 is in the position, the top block 41 is squeezed and pressed against the inclined surface on the top of the protrusion 40, so that the protrusion 40 moves downward, driving the slide plate 36 and the filter plate 38 to move downward. The slide plate 36 moves downward and presses the second spring 37. As the top block 41 continues to rotate, when the top block 41 is separated from the protrusion 40, under the action of the second spring 37, the slide plate 36 and the filter plate 38 move upward and vibrate, thereby reciprocating. The reciprocating screw rod 19 rotates and drives the filter plate 38 to continue to vibrate, which effectively prevents the filter plate 38 from being blocked by gypsum.

[0041] An operating method of an industrial waste gas treatment device for preventing air pollution, the operating method is applicable to the above-mentioned industrial waste gas treatment device for preventing air pollution, and the steps of the method are as follows: S1: placing the housing 1 in a factory, filling the second liquid accumulation chamber 34 with limestone slurry, starting the air pump 12, and pumping the gas in the factory into the housing 1 along the air inlet groove 14; S2: Start the four nozzles 5 to form a closed loop to spray the limestone slurry with the gas flowing upward, and use the electric telescopic rod 8 to control the swing of the four nozzles 5 to increase the spraying range; S3: The motor 18 is started to drive the reciprocating screw 19 to rotate counterclockwise, so that the receiving plate 21 generates centrifugal force to separate the gypsum from the limestone slurry. When the gypsum on the piston plate 27 is cleaned, the motor 18 is started to drive the reciprocating screw 19 to rotate clockwise, so that the piston plate 27 moves up and down.

[0042] When in use, the shell 1 is placed in a factory, limestone slurry is loaded into the second liquid accumulation chamber 34, and the air pump 12 is started to draw the gas in the factory into the shell 1 along the air inlet groove 14. The gas after entering the shell 1 flows upward along the inclined surface at the bottom of the guide plate 2, and the flow range of the gas in the shell 1 is reduced through the provided guide plate 2, so that the gas is more concentrated, which is convenient for the limestone slurry sprayed subsequently to fully contact with the gas. The water pump 15 is started to draw the limestone slurry along the water pumping pipe 16 and the four diversion pipes 17 to the four nozzles 5, and a closed loop is formed through the four nozzles 5 to spray the limestone slurry on the gas flowing upward, so that the sulfur dioxide in the gas reacts with the limestone slurry, and the rack 9 is controlled to move back and forth left and right through the electric telescopic rod 8 to drive The gear ring 7 rotates back and forth, and while the gear ring 7 rotates, it drives the four gears 6 to rotate at the same time, so that the four rotating shafts 4 rotate at the same time, and drives the four nozzles 5 to rotate at the same time, thereby increasing the spray range of the limestone slurry. The limestone slurry sprayed from the nozzle 5 hits 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 and falls to the drainage groove 10, the limestone slurry enters the drainage groove 10 and continues to slide, and falls when passing through several lower water tanks 11, thereby forming multiple water curtains for the limestone slurry to react with the gas flowing upward, thereby extending the reaction time of the gas and the limestone slurry, and the sprayed limestone slurry falls on the receiving plate 21, and the motor 18 is started to drive the accumulation plate 20 and the receiving plate 21 to rotate. The lower pressure ring 22 is provided to block the limestone slurry in the receiving plate 21 to prevent the limestone slurry from being thrown out. Under the action of centrifugal force, the limestone slurry is easily thrown out along the sieve hole 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 hole 43 falls on the top of the guide ring 24 and slides downward along the guide ring 24. The sliding speed of the limestone slurry is slowed down by the provided several blocking rings 25, and a drop is formed at the end of the blocking ring 25, so that the limestone slurry forms a water curtain, increasing the coverage area of ​​the limestone slurry. The limestone slurry passing through the guide ring 24 falls into the first liquid accumulation chamber 33. After the gas enters the shell 1 along the air inlet groove 14, it flows downward along the arc surface at the bottom of the guide ring 24. Under the guidance of the guide ring 24, the gas collides with the limestone slurry in the first liquid accumulation chamber 33, so that the sulfur dioxide in the gas reacts with the limestone slurry. The gas passing through the guide ring 24 continues to flow upward. When the limestone slurry in the first liquid accumulation chamber 33 is flush with the drainage groove 44, the excess limestone slurry re-enters the second liquid accumulation chamber 34 along the connecting groove 45 of the drainage groove 44. When the motor 18 is turned off, the gypsum slides down along the inclined surface of the top of the receiving plate 21 and accumulates in the accumulation plate 20. The spiral top cover 42 is opened by screwing, so that the gypsum in the accumulation plate 20 can be easily taken out. When the limestone slurry is thrown out from the sieve hole 43, a ring-shaped water curtain is formed, which is convenient for reacting with the gas passing here. When the receiving plate 21 rotates, a plurality of first spoilers 23 are driven to rotate.During the rotation of the first spoiler 23, its inclined surface exerts a downward pressure on the gas flowing upward. Under the action of the inclined surface at the bottom of the first spoiler 23, part of the gas is pushed downward to collide with the limestone slurry flowing along the baffle ring 25, thereby extending the reaction time between the gas and the limestone slurry. The gypsum produced by the reaction with the limestone slurry in the first liquid accumulation chamber 33 is accumulated on the piston plate 27. It is necessary to clean the gypsum on the piston plate 27 regularly. When cleaning the gypsum on the piston plate 27, start the motor 18 to drive the reciprocating screw 19 to rotate clockwise, so that the slider 26 rotates clockwise, and drives the limit block 29 to rotate clockwise. When the limit block 29 rotates to the limit slide groove 31, under the action of the first spring 30, the limit block 2 9 enters the limiting slide groove 31. As the reciprocating screw 19 continues to rotate, the straight surface of one side of the limiting card block 29 presses against the limiting slide groove 31 and cannot rotate. Therefore, when the reciprocating screw 19 rotates clockwise, it drives the slider 26 and the piston plate 27 to move up and down reciprocatingly. When the piston plate 27 moves upward and is flush with the drainage groove 44, the gypsum on the piston plate 27 slides down along the inclined surface of the piston plate 27 and passes through the drainage groove 44 and the connecting groove 45 into the second liquid accumulation chamber 34. After the gypsum on the piston plate 27 is cleaned, the motor 18 is started to drive the reciprocating screw 19 to rotate counterclockwise. Under the action of the adjusting component, the slider 26 rotates counterclockwise, driving the limiting card block 29 to rotate counterclockwise. When the limiting card block 29 rotates to the limiting slide groove 31, in the first elastic Under the action of the spring 30, the limit block 29 enters the limit slot 31. As the reciprocating screw 19 continues to rotate, the inclined surface on one side of the limit block 29 presses against the limit slot 31. Under the extrusion of the limit slot 31, the limit block 29 moves into the piston plate 27, pressing the first spring 30. As a result, when the reciprocating screw 19 rotates counterclockwise, the slider 26 and the piston plate 27 are driven to rotate counterclockwise. When the piston plate 27 rotates, a plurality of second spoiler plates 32 are driven to rotate. The rotation of the second spoiler plates 32 causes the limestone slurry in the first liquid accumulation chamber 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. The limestone slurry falling from the connecting groove 45 falls on the filter plate 38 and passes through the filter plate 38. The filter plate 38 acts on the limestone slurry, thereby separating the limestone slurry from the gypsum formed by the reaction. The filtered limestone slurry passes through the filter plate 38 and is accumulated at the bottom of the second liquid accumulation chamber 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. The reciprocating screw 19 rotates while driving the fixed plate 39 to rotate, so that the top block 41 rotates. When the top block 41 rotates to a position close to the protrusion 40, under the pressure of the top block 41, it presses against the inclined surface of the top of the protrusion 40, so that the protrusion 40 moves downward, driving the slide plate 36 and the filter plate 38 to move downward. The slide plate 36 moves downward and presses the second spring 37. As the top block 41 continues to rotate, when the top block 41 is separated from the protrusion 40, under the action of the second spring 37,The slide plate 36 and the filter plate 38 move upward and vibrate, and the reciprocating screw 19 rotates and drives the filter plate 38 to vibrate continuously, effectively preventing the filter plate 38 from being blocked by gypsum.
