Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, and in particular to a spray tower. Background Technology

[0002] Among numerous waste gas treatment processes, spray towers have become one of the mainstream technologies for industrial flue gas purification due to their simple structure, flexible operation, low cost, and strong adaptability. For example, the existing technology, disclosed in CN220677368U, describes a high-quality stainless steel processing turnover rack and its usage method. This device uses a water pump to extract purification liquid from a water tank and sprays it onto the gas inside the tower through connecting water pipes and spray pipes, thus purifying the gas. By incorporating filter elements, permeable grids, and single-layer filter screens, the purification liquid is easily filtered, reducing energy consumption and equipment wear caused by high-density foam generated in the purification liquid. The stability of the spray tower is improved by installing support sleeves, support screws, and support seats on the support plate. However, this device uses traditional zoned spraying for purification, requiring separate operation of two different solutions. Furthermore, the purification efficiency is easily reduced due to spray intervals, making it difficult to guarantee overall spray efficiency. Additionally, this device only purifies the gas through spraying, resulting in a relatively simple overall method. To address these technical shortcomings, a solution is proposed. Summary of the Invention

[0003] To overcome the aforementioned deficiencies of the prior art, the present invention provides a spray tower that enhances the spatial separation of two solutions through the centrifugal force of the spray mechanism, reducing cross-mixing and avoiding ineffective neutralization of acid and alkali solutions. Combined with a recovery and anti-clogging component, the activated carbon balls inside the fixed cylinder are promptly recovered and cleaned. Multiple purification methods work together to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a spray tower, comprising a spray tower, an air inlet fixed at the bottom of one side of the spray tower, and a suction hood fixed on the upper surface of the spray tower, an exhaust pipe fixed at the top of the suction hood, an anti-clogging recovery component and a spraying mechanism respectively installed inside the spray tower, and a collection box fixed on one side of the spray tower at the position corresponding to the anti-clogging recovery component.

[0005] Furthermore, the spraying mechanism includes an alkaline storage tank and an acidic storage tank fixed inside the spraying tower. A rotating block is rotatably connected to the bottom of the acidic storage tank. A slot is opened on the upper surface of the rotating block. A worm gear is fixed to the bottom of the alkaline storage tank. A first rack is fixed to the inner side of the worm gear. A worm is rotatably connected to the rear end of the worm gear and is connected to the inside of the spraying tower. A rotating shaft is connected through the inside of the worm.

[0006] Furthermore, several diversion pipes are fixed at equal intervals on the inner side of the alkaline storage tank, and a guide pipe is fixed at the center of the diversion pipes. A rotating disk is rotatably connected to the bottom of the guide pipe. Several nozzles are fixed at equal intervals on the bottom of the worm gear disk corresponding to the position of the rotating block and on the outer side of the bottom of the rotating disk. A second rack is fixed on the outer side of the rotating disk. Three gears rotatably connected to the bottom of the acidic storage tank are equidistantly meshed between the second rack and the first rack.

[0007] Furthermore, the anti-clogging recycling component includes a fixed cylinder fixed inside the spray tower at a position above the spray mechanism. An auger is rotatably connected inside the fixed cylinder, and several activated carbon balls are arranged inside the fixed cylinder. A screw rod is fixed to one side of the auger, penetrating and extending into the collection box. A movable plate is sleeved on the outer layer of one side of the screw rod. A first spring sleeved on the outer layer of the screw rod is fixed between the movable plate and the inside of the collection box.

[0008] Furthermore, a through-hole plate is fixed to the bottom of the fixed cylinder, and a column is provided below the through-hole plate at the position corresponding to the through hole. Each adjacent column is fixedly connected by a connecting rod, and a support plate that is slidably connected to the inside of the spray tower is fixed to the bottom of the columns on the same side.

[0009] Furthermore, the bottom of the support plate is provided with a conical block rotatably connected to the inside of the spray tower, and a number of guide columns are fixed at equal intervals on the upper surface of the support plate. The outer layer of the guide columns is sleeved with a second spring fixed between the support plate and the spray tower.

[0010] Furthermore, one side of the auger, the conical block, and the rotating shaft all extend through and to the outside of the spray tower, and a synchronous pulley is fixed thereon. A motor is fixed on the upper surface of the spray tower, and a synchronous pulley is fixed to the transmission end of the motor. Each adjacent synchronous pulley is connected to the other by a synchronous belt.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0012] 1. This invention includes a spraying mechanism that separates two liquids, an acidic storage tank and an alkaline storage tank. A worm gear and worm wheel work together to drive a rotating block, while a first rack, a second rack, and a gear drive a rotating disk. The liquids inside the alkaline and acidic storage tanks flow into the rotating block and disk respectively. During spraying, the simultaneous spraying of the two liquids enhances the neutralization reaction rate, and the centrifugal force of rotation enhances the spatial separation of the two solutions, reducing cross-mixing. This avoids ineffective neutralization of the acid and alkali solutions and achieves continuous and efficient processing. Its dynamic characteristics enhance gas-liquid mass transfer, effectively purifying internal atmospheric pollution.

[0013] 2. This invention includes an anti-clogging and recycling component. After neutralizing pollutants in the atmosphere, the activated carbon balls inside the fixed cylinder further purify the pollutants. The cone-shaped block rotates continuously, lifting the support frame and creating a reciprocating lifting effect with the second spring. This cleans the inside of the perforated plate, preventing blockages. When the activated carbon balls become less effective due to excessive use, the auger rotates in the opposite direction, causing the screw to rotate in the opposite direction, which in turn moves the movable plate. The activated carbon balls move with the auger until they enter the collection box, thus recycling them and facilitating the placement of new activated carbon balls into the fixed cylinder, ensuring that the subsequent purification effect is not reduced.

[0014] In summary, this invention utilizes a spray pipe mechanism to enhance the neutralization reaction rate through the synchronous rotation of a rotating disk and a rotating block. It also enhances the spatial separation of the two solutions through centrifugal force, reducing cross-mixing. This not only avoids ineffective neutralization of acid and alkali solutions but also enables continuous and efficient treatment. Combined with a recovery and anti-clogging component, the activated carbon balls inside the fixed cylinder are promptly recovered and cleaned, ensuring that efficiency is not reduced due to blockage during air pollution purification. Furthermore, it prevents ineffective adsorption of activated carbon balls due to prolonged use, thus guaranteeing overall high-efficiency purification. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0025] This embodiment addresses the problems in existing spray towers for effectively purifying air pollution, such as the possibility of stainless steel pipes sliding and falling during transport, and the need for significant manpower and resources for loading and unloading, resulting in overall inconvenience.

[0026] like Figure 5-8As shown, a spray tower includes a spray tower 1. An air inlet 7 is fixed to the bottom of one side of the spray tower 1, and a suction hood 2 is fixed to the upper surface of the spray tower 1. An exhaust pipe 3 is fixed to the top of the suction hood 2. An anti-clogging recovery component 9 and a spraying mechanism 10 are respectively installed inside the spray tower 1. A collection box 8 is fixed to one side of the spray tower 1 at the position corresponding to the anti-clogging recovery component 9. The spraying mechanism 10 includes an alkaline storage tank 24 and an acidic storage tank 25 fixed inside the spray tower 1. External connection ports are provided on the sides of the alkaline storage tank 24 and the acidic storage tank 25 to replenish the internal solution. A rotating block 31 is rotatably connected to the bottom of the acidic storage tank 25. A slot 28 is opened on the upper surface of the rotating block 31, through which the solution inside the acidic storage tank 25 enters the rotating block 31. Inside, a worm gear 29 is fixed to the bottom of the alkaline storage tank 24. A first rack 34 is fixed to the inner side of the worm gear 29. A worm 33 rotatably connected to the inside of the spray tower 1 is meshed at the rear end of the worm gear 29. A rotating shaft 32 is connected through the inside of the worm 33. Several diversion pipes 26 are fixed at equal intervals inside the alkaline storage tank 24. A guide pipe 27 is fixed at the center position of the diversion pipes 26. A rotating disk 30 is rotatably connected to the bottom of the guide pipe 27. Several nozzles 16 are fixed at equal intervals at the bottom of the worm gear 29 corresponding to the position of the rotating block 31 and the outer side of the bottom of the rotating disk 30. The nozzles 16 are inclined at a 15° angle to the horizontal direction. A second rack 36 is fixed to the outer side of the rotating disk 30. Three gears 35 rotatably connected to the bottom of the acidic storage tank 25 are meshed at equal intervals between the second rack 36 and the first rack 34.

[0027] During atmospheric spray purification, gas is introduced into the spray tower 1 through the air inlet 7. The motor 4, in conjunction with the synchronous pulley 5 and synchronous belt 6, drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32, in conjunction with the worm gear 33 and worm wheel 29, drives the slot 28. Simultaneously, during the rotation of the worm gear 33, in conjunction with the gear 35, drives the second rack 36 to rotate the rotating disk 30. When the rotating disk 30 and the worm wheel 29 rotate synchronously, the spray head 16 is activated to discharge the alkaline solution and acidic solution inside, thereby improving the overall neutralization rate. The centrifugal force of rotation enhances the spatial separation of the two solutions and reduces cross-mixing. This avoids ineffective neutralization of acid and alkali solutions and achieves continuous and efficient treatment. Example

[0028] This embodiment addresses the problem that stainless steel plates in existing spray towers used for effectively purifying air pollution may suffer excessive wear due to collisions during transport.

[0029] like Figure 1-4As shown, the embodiment is a spray tower, and the anti-clogging and recycling component 9 includes a fixed cylinder 15 fixed inside the spray tower 1 at a position corresponding to the upper part of the spray mechanism 10. An auger 14 is rotatably connected inside the fixed cylinder 15, and several activated carbon balls are arranged inside the fixed cylinder 15. A lead screw 11 is fixed to one side of the auger 14, penetrating and extending into the collection box 8. A movable plate 13 is sleeved on the outer layer of one side of the lead screw 11. An internal thread is provided inside the movable plate 13 corresponding to the position of the lead screw 11. A first spring 12, sleeved on the outer layer of the lead screw 11, is fixed between the movable plate 13 and the inside of the collection box 8. The first spring 12 prevents the movable plate 13 from excessively moving due to the continuous rotation of the lead screw 11 and causing it to disengage. The reverse force of the first spring 12 pulls the movable plate 13 to always keep it at the edge position of the lead screw 11. A through-hole plate 17 is fixed to the bottom of the fixed cylinder 15. Several slots are equally spaced on the top of the fixed cylinder 15. The sides of the fixed cylinder 15 are closed. A column 18 is set below the through-hole plate 17 at the position corresponding to the through hole. Each adjacent column 18 is fixedly connected by a connecting rod 22. A support plate 23 that is slidably connected to the inside of the spray tower 1 is fixed to the bottom of the columns 18 on the same side. A conical block 21 that is rotatably connected to the inside of the spray tower 1 is set at the bottom of the support plate 23. Several guide columns 19 are equally spaced fixed on the upper surface of the support plate 23. A second spring 20 that is fixed between the support plate 23 and the spray tower 1 is sleeved on the outer layer of the guide column 19. The guide column 19 is slidably connected to the inside of the spray tower 1. Screw 14, conical block 21 Synchronous pulleys 5 are fixed to the outside of the spray tower 1, extending through one side of the rotating shaft 32. A motor 4 is fixed to the upper surface of the spray tower 1. The transmission end of the motor 4 is fixed to the synchronous pulleys 5. Each adjacent synchronous pulley 5 is connected by a synchronous belt 6. The synchronous operation effect is formed by the linkage between the synchronous pulleys 5 and the synchronous belt 6.

[0030] After starting motor 4, the synchronous pulley 5 and synchronous belt 6 work together to drive the conical block 21 to rotate. The rotation of the conical block 21 creates a reciprocating impact and lifting effect on the support plate 23. At the same time, the second spring 20 creates a reciprocating motion effect, thereby driving the column 18 to continuously insert into the through hole of the through-hole plate 17, cleaning and unblocking the through hole to prevent blockage. Meanwhile, the synchronous pulley 5 and synchronous belt 6 drive the auger 14 to rotate, and the repeated lifting effect of the column 18 makes the activated carbon balls evenly distributed in the fixed cylinder 15. Inside, the activated carbon balls fully absorb odors and other pollutants from the gas. When the adsorption capacity decreases due to excessive use of activated carbon balls, the motor 4 is started to rotate in the reverse direction, which in turn drives the auger 14 to rotate in the reverse direction. At this time, the auger 14 drives the lead screw 11 to rotate in the reverse direction, and the lead screw 11 drives the movable plate 13 to move into the collection box 8. At the same time, the auger 14 continues to rotate, moving the activated carbon balls towards the collection box 8 until all the activated carbon balls fall into the collection box 8. This process collects the activated carbon balls with reduced adsorption capacity for subsequent reuse, while avoiding a decrease in purification effect due to subsequent adsorption capacity, thus maintaining high-efficiency purification.

[0031] The working process and principle of this invention:

[0032] Step 1: During atmospheric spray purification, gas is introduced into the spray tower 1 through the air inlet 7. The motor 4, in conjunction with the synchronous pulley 5 and synchronous belt 6, drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32, in conjunction with the worm gear 33 and worm wheel 29, drives the slot 28. Simultaneously, during the rotation of the worm gear 33, in conjunction with the gear 35, drives the second rack 36 to rotate the rotating disk 30. When the rotating disk 30 and the worm wheel 29 rotate synchronously, the spray nozzles 16 are activated to discharge the alkaline and acidic solutions inside, thereby improving the overall neutralization rate. The centrifugal force of rotation enhances the spatial separation of the two solutions, reducing cross-mixing. This avoids ineffective neutralization of acid and alkali solutions and achieves continuous and efficient treatment.

[0033] Step Two: After starting the motor 4, the synchronous pulley 5 and the synchronous belt 6 work together to drive the conical block 21 to rotate. The rotation of the conical block 21 creates a reciprocating impact and lifting effect on the support plate 23. At the same time, the second spring 20 creates a reciprocating motion effect, thereby driving the column 18 to continuously insert into the through hole of the through-hole plate 17, cleaning and unblocking the through hole to prevent blockage. Meanwhile, the synchronous pulley 5 and the synchronous belt 6 drive the auger 14 to rotate, and the repeated lifting effect of the column 18 makes the activated carbon balls evenly distributed in the fixed cylinder 15. Inside, the activated carbon balls fully absorb odors and other pollutants from the gas. When the adsorption capacity decreases due to excessive use of activated carbon balls, the motor 4 is started to rotate in the reverse direction, which in turn drives the auger 14 to rotate in the reverse direction. At this time, the auger 14 drives the lead screw 11 to rotate in the reverse direction, and the lead screw 11 drives the movable plate 13 to move into the collection box 8. At the same time, the auger 14 continues to rotate, moving the activated carbon balls towards the collection box 8 until all the activated carbon balls fall into the collection box 8. This process collects the activated carbon balls with reduced adsorption capacity for subsequent reuse, while avoiding a decrease in purification effect due to reduced adsorption capacity, thus maintaining high-efficiency purification.

[0034] In summary, by using two sets of nozzles 16 to simultaneously spray acid and alkali solutions onto the atmosphere in a rotating manner, cross-mixing is reduced. This avoids ineffective neutralization of the acid and alkali solutions and enables continuous and efficient treatment. Combined with the anti-clogging recovery component 9, the activated carbon balls inside the fixed cylinder 15 are promptly recovered and cleaned, ensuring that the efficiency of air pollution purification is not reduced due to clogging. At the same time, it avoids ineffective adsorption of activated carbon balls due to prolonged use, thus ensuring overall high-efficiency purification.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
