Description

Technical Field

[0001] The present invention relates to the technical field of spray towers, and particularly relates to a waste gas treatment rain curtain type spray tower. Background Art

[0002] The spray tower exists as a treatment device for environmental protection waste gas treatment. According to the working principle, it is divided into a circulating water spray tower, an alkali solution spray tower, and an acid solution spray tower. As a treatment device for environmental protection waste gas treatment, a reasonable spray material and spray process are selected according to the different properties of the waste gas. When the waste gas enters from the bottom of the tower body, it contacts the spray medium sprayed by the spray tower. After contact, the waste gas or oil stain is wrapped by water droplets. The water droplets wrapping the pollutants collide again, increasing the surface area and gravity. Under the influence of gravity, the water droplets wrapping the pollutants fall into the bottom of the spray tower. The heavier pollutants sink to the bottom of the tower body, and the lighter pollutants float on the surface of the circulating water body.

[0003] For example, the Chinese utility model patent with the application number 202121500798.8 and the name of a gravity-sensing packing flushing spray tower discloses a gravity-sensing packing flushing spray tower. The above-mentioned utility model includes: a tower body, an air inlet structure, an air outlet structure, a packing layer, a control component, a spray pipe, and a flushing pipe. The tower body is vertically arranged on a horizontal plane; the air inlet structure is connected to the tower body; the air outlet structure is connected to the tower body; the packing layer includes a packing support plate; the control component includes a gravity sensing plate and a controller. The packing support plate is vertically slidably connected to the inner wall of the tower body through the gravity sensing plate, and the controller is control-connected to the gravity sensing plate; the spray pipe is arranged above the packing layer for spraying spray liquid into the packing layer; the flushing pipe is used for spraying cleaning liquid into the packing layer. The above-mentioned utility model performs gravity sensing on the adhesive pollution generated after the reaction of the waste gas and the spray liquid, and controls the lifting of the packing support plate and the flushing of the packing layer; it can avoid the congestion of the packing layer and does not need to frequently maintain the spray tower and replace the packing.

[0004] In the above patent, a gravity sensing device is set to sense whether the packing layer needs to be cleaned. However, in the actual use process, the cleaning of the packing will affect the treatment effect of the waste gas. Therefore, when the packing needs to be moved down for treatment, the waste gas treatment operation is not carried out inside the tower body. And after the packing is seriously polluted, the entire device needs to be paused to replace the packing, which is very troublesome to handle, affects the efficiency during waste gas treatment, and has certain deficiencies.

Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0021] Please refer to FIGS. 1-9. An exhaust gas treatment rain curtain type spray tower includes a tower body 1 and a spray pipe 101 disposed in the tower body 1. An inspection window 102 is further provided on the tower body 1. A packing plate 201 for placing packing is rotatably connected in the tower body 1. The packing plate 201 is divided into four storage spaces 203 by a partition plate 202; further includes a blocking mechanism for blocking two of the storage spaces 203. The blocking mechanism includes a special-shaped sealing frame 301 fixedly connected to the tower body 1, an arc-shaped sealing plate 302, and a cleaning component disposed in the special-shaped sealing frame 301. Sealing strips 303 are provided on both the special-shaped sealing frame 301 and the arc-shaped sealing plate 302. A bevel sealing frame 304 is fixedly connected to the special-shaped sealing frame 301; further includes a driving component. The driving component drives the storage space 203 to rotate and switch through a first triggering component, and the four storage spaces 203 are switched to perform intermittent exhaust gas treatment. And a second triggering component is used to drive the cleaning component to flush the packing in one of the storage spaces 203 blocked by the blocking mechanism, and the packing in another storage space 203 of the blocking mechanism is replaced through the inspection window 102.

[0022] Specifically, this exhaust gas treatment rain curtain type spray tower includes a tower body 1 and a spray pipe 101 disposed in the tower body 1. An inspection window 102 is further provided on the tower body 1. The tower body 1, the spray pipe 101, and the inspection window 102 are all components of an existing spray tower and will not be elaborated here. A packing plate 201 for placing packing is rotatably connected in the tower body 1. The packing plate 201 is disposed at the bottom of the spray pipe 101. The packing on the packing plate 201 is for providing surface area and contact surface to promote the mass transfer and heat transfer between the exhaust gas and the liquid. The packing plate 201 is divided into four storage spaces 203 by a partition plate 202, and the four storage spaces 203 have the same size and shape; further includes a blocking mechanism for blocking two of the storage spaces 203 so that the two blocked storage spaces 203 do not perform the exhaust gas treatment work. The blocking mechanism includes a special-shaped sealing frame 301 fixedly connected to the tower body 1, an arc-shaped sealing plate 302, and a cleaning component disposed in the special-shaped sealing frame 301. Sealing strips 303 are provided on both the special-shaped sealing frame 301 and the arc-shaped sealing plate 302. A bevel sealing frame 304 is fixedly connected to the special-shaped sealing frame 301. For the specific shapes of the special-shaped sealing frame 301, the arc-shaped sealing plate 302, the sealing strip 303, and the bevel sealing frame 304, please refer to the attached Figure 6, a sealing strip 303 is provided at the connection between the special-shaped sealing frame 301, the arc-shaped sealing plate 302 and the material storage space 203 to increase the sealing of the structural connection and ensure the closure of the blocked space; it also includes a driving component, which drives the material storage space 203 to rotate and switch through the first trigger component. The four material storage spaces 203 are switched to perform intermittent waste gas treatment, and the cleaning component is driven by the second trigger component to flush the filler in one of the material storage spaces 203 blocked by the blocking mechanism. The filler in another material storage space 203 in the blocking mechanism is replaced through the inspection window 102. When the driving component drives the four material storage spaces 203 to switch through the first trigger component, the second trigger component does not trigger the cleaning component to work. After the first trigger component triggers the completion of the switching of the material storage space 203, at this time, the cleaning component moves under the action of the second trigger component to effectively flush the filler in the material storage space 203. The operation is simple and can improve the service life of the filler.

[0023] In the embodiment further provided by the present invention, the cleaning component includes a threaded rod 401 rotatably connected in the special-shaped sealing frame 301; a cleaning spray head 402 is threadedly connected to the threaded rod 401, and the cleaning spray head 402 is communicated with an external cleaning liquid through a water pipe 403.

[0024] Preferably, the cleaning component includes a threaded rod 401 rotatably connected in the special-shaped sealing frame 301; a cleaning spray head 402 is threadedly connected to the threaded rod 401, and the cleaning spray head 402 is communicated with an external cleaning liquid through a water pipe 403. When the cleaning spray head 402 moves linearly under the rotation of the threaded rod 401, the water pipe 403 can introduce the external cleaning liquid into the cleaning spray head 402, and the filler can be flushed through the pressurization of the cleaning spray head 402. The water pipe 403 needs to adopt a pipeline with a certain stretchability.

The moving frame 504 is connected to the support seat 501 through an elastic telescopic rod 505.

[0026] Preferably, the driving assembly includes a support base 501 fixedly connected to the tower body 1. A driving motor 502 is arranged on the support base 501. The support base 501 is arranged in an L shape. By providing the support base 501, it is used to support the driving motor 502. The driving motor 502 is connected to an external power supply and a control switch. The output end of the driving motor 502 is provided with a cam 503. An outer portion of the cam 503 is provided with a moving frame 504. The moving frame 504 is connected to the support base 501 through an elastic telescopic rod 505. When the driving motor 502 operates, it can drive the cam 503 to rotate. The rotation of the cam 503 drives the moving frame 504 to move synchronously. Since the movement of the moving frame 504 is affected by the elastic telescopic rod 505, the cam 503 can only drive the moving frame 504 to move up and down after rotation.

[0027] In an embodiment further provided by the present invention, the first triggering assembly includes a first vertical plate 601 slidably connected to the moving frame 504. First teeth 602 are arranged on the first vertical plate 601. A rotating rod 603 is rotatably connected in the tower body 1. A first gear 604 is arranged on the rotating rod 603. During the vertical upward movement of the first vertical plate 601, the first teeth 602 are driven to engage with the first gear 604. The rotating rod 603 is connected to the packing plate 201 through a conduction unit.

[0028] Preferably, the first triggering assembly includes a first vertical plate 601 slidably connected to the moving frame 504. A slot for the first vertical plate 601 to move needs to be opened on the moving frame 504. First teeth 602 are arranged on the first vertical plate 601. A rotating rod 603 is rotatably connected in the tower body 1. A first gear 604 is arranged on the rotating rod 603. During the vertical upward movement of the first vertical plate 601, the first teeth 602 are driven to engage with the first gear 604. The rotating rod 603 is connected to the packing plate 201 through a conduction unit. When the length of the first teeth 602 meshes with the first gear 604, it is ensured that the rotation of the first gear 604 drives the packing plate 201 to rotate 90° through the rotating rod 603 and the transmission unit, so that after the four storage spaces 203 are switched, there are always two storage spaces 203 blocked by the blocking mechanism.

[0029] In an embodiment further provided by the present invention, the conduction unit includes a central axis rod 701 fixedly connected to the packing plate 201. A first bevel gear 702 is fixedly connected to the central axis rod 701. A second bevel gear 703 is arranged on the rotating rod 603. The first bevel gear 702 meshes with the second bevel gear 703.

[0030] Preferably, the conduction unit includes a shaft rod 701 fixedly connected to the packing plate 201, and a first bevel gear 702 is fixedly connected to the shaft rod 701; a second bevel gear 703 is arranged on the rotating rod 603, and the first bevel gear 702 meshes with the second bevel gear 703. When the rotating rod 603 rotates, the second bevel gear 703 arranged thereon meshes with the first bevel gear 702 on the shaft rod 701, which can synchronously drive the shaft rod 701 to rotate 90°. The shaft rod 701 is arranged at the center position of the four material storage spaces 203. By rotating the shaft rod 701, the four material storage spaces 203 can be driven to rotate for switching.

[0031] In an embodiment further provided by the present invention, a limiting component for driving the first vertical plate 601 to move horizontally is arranged on the tower body 1. The limiting component includes a fixing plate 801 fixedly connected to the tower body 1; a diamond-shaped groove 802 is formed in the fixing plate 801, and a sliding rod 803 is fixedly connected to the first vertical plate 601. The sliding rod 803 is slidably connected in the diamond-shaped groove 802.

[0032] Preferably, a limiting component for driving the first vertical plate 601 to move horizontally is arranged on the tower body 1. The limiting component includes a fixing plate 801 fixedly connected to the tower body 1; a diamond-shaped groove 802 is formed in the fixing plate 801, and a sliding rod 803 is fixedly connected to the first vertical plate 601. The sliding rod 803 is slidably connected in the diamond-shaped groove 802. By setting the cooperation of the diamond-shaped groove 802 and the sliding rod 803, the sliding of the first vertical plate 601 on the moving frame 504 can be controlled, so that when the first vertical plate 601 moves upward, the first tooth 602 drives the first gear 604 to rotate meshingly. When the first vertical plate 601 moves downward and resets, under the influence of the diamond-shaped groove 802 and the sliding rod 803, the first tooth 602 on the first vertical plate 601 does not contact the first gear 604, so as not to drive the first gear 604 to rotate.

[0033] In an embodiment further provided by the present invention, the second triggering component includes a second vertical plate 901 fixedly connected to the moving frame 504; second teeth 902 are arranged on the second vertical plate 901, and a second gear 903 is arranged at one end of the threaded rod 401. During the vertical movement of the second vertical plate 901, the second teeth 902 drive the second gear 903 to rotate meshingly.

During the vertical movement of the second vertical plate 901, the second tooth 902 is driven to engage with the second gear 903. When the first tooth 602 on the first vertical plate 601 does not contact the first gear 604, the second vertical plate 901 drives the second tooth 902 to contact the second gear 903 and drive it to rotate. When the second gear 903 drives the threaded rod 401 to rotate, the cleaning assembly on the storage space 203 can be driven to work and move, so that the filler in the storage space 203 can be flushed, thereby improving the use effect of the filler.

The diversion assembly can be provided on both sides, and both diversion assemblies are provided above the unblocked mechanism, so as to guide the waste gas flowing above the two storage spaces 203 in use. Through the third trigger assembly, the diversion assembly can be driven to rotate, so that the flowing waste gas can be evenly introduced into the tower body 1 and fully contact the liquid sprayed by the spray pipe 101.

[0037] In an embodiment further provided by the present invention, the third trigger assembly includes a cross plate 121 fixedly connected to the second vertical plate 901, and a third vertical plate 122 and a fourth vertical plate 123 are provided on the cross plate 121; a third tooth 124 is provided on the third vertical plate 122, a fourth tooth 125 is provided on the fourth vertical plate 123, a third gear 126 is provided on the cross bar 111, and during the movement of the cross plate 121, the third tooth 124 and the fourth tooth 125 are successively driven to engage with the third gear 126.

[0038] Preferably, the third trigger assembly includes a cross plate 121 fixedly connected to the second vertical plate 901. A third vertical plate 122 and a fourth vertical plate 123 are arranged on the cross plate 121.

[0040] Preferably, a filtering assembly is further arranged in the tower body 1. An air inlet pipe 10 is communicated with the tower body 1 between the filtering assembly and the packing plate 201. The filtering assembly includes a conical hopper 131 fixedly connected in the tower body 1 and an arc-shaped filtering frame 132. The discharge port at the bottom of the conical hopper 131 is aligned with the arc-shaped filtering frame 132. Through the conical hopper 131, the liquid reacted with the exhaust gas can be introduced into the arc-shaped filtering frame 132 for filtering. A rotating rod 133 is rotatably connected in the arc-shaped filtering frame 132. One end of the rotating rod 133 is connected to the center point of the cam 503. A plurality of cleaning plates 134 are arranged on the rotating rod 133. A receiving frame 135 is communicated with one side of the tower body 1, and an inclined plate 136 is arranged between the receiving frame 135 and the arc-shaped filtering frame 132. When the cam 503 rotates, the cleaning plates 134 can be driven to rotate through the rotating rod 133. By rotating the cleaning plates 134, the filter residues remaining on the arc-shaped filtering frame 132 can be introduced into the receiving frame 135 through the inclined plate 136, avoiding the influence of too much filter residue on the arc-shaped filtering frame 132 on its filtering effect. The filtered liquid can be reused for spraying according to needs.

[0041] Working principle: During operation, exhaust gas is introduced into the interior of the tower body 1 through the intake pipe 10 on the tower body 1. Then, the nozzles on the spray pipe 101 are opened so that the liquid is sprayed through the spray pipe 101. After the gas enters the tower body 1, it will first enter the packing plate 201 and come into contact with the packing in the packing plate 201. Since the two storage spaces 203 on the packing plate 201 cannot allow the exhaust gas to flow through, the gas will flow through the other two unblocked storage spaces 203 and come into contact with and react with the liquid sprayed from the spray pipe 101. When the packing is used for a long time and crystallization occurs, affecting its use, it is necessary to clean the packing. At this time, by starting the drive motor 502 on the support base 501, after the drive motor 502 works, it drives the cam 503 in the moving frame 504 to rotate. After the cam 503 rotates, it will drive the moving frame 504 to move. The movement of the moving frame 504 will drive the first vertical plate 601 and the second vertical plate 901 to move synchronously. When the first vertical plate 601 moves upward, it will also be affected by the diamond-shaped groove 802 and the slide bar 803, so that the first tooth 602 on the first vertical plate 601 will contact the first gear 604 on the rotating rod 603 and drive the first gear 604 to drive the rotating rod 603 to rotate. The rotation of the rotating rod 603 is in contact and cooperation with the second bevel gear 703 and the first bevel gear 702, so that the shaft rod 701 on the packing plate 201 can drive the packing plate 201 to rotate synchronously. The rotation of the packing plate 201 drives the four storage spaces 203 to switch, so that the storage space 203 that needs to be cleaned moves to the bottom of the special-shaped sealing frame 301. After the switching of the storage space 203 is completed, the sealing strips 303 on the special-shaped sealing frame 301 and the arc-shaped sealing plate 302 can seal the switched storage space 203; When the first vertical plate 601 continues to move upward and the first tooth 602 is separated from the first gear 604, at this time, the second tooth 902 on the second vertical plate 901 will contact the second gear 903 on the threaded rod 401 and drive the second gear 903 to drive the threaded rod 401 to rotate. After the threaded rod 401 rotates, it can drive the cleaning nozzle 402 arranged thereon to move. The movement of the cleaning nozzle 402 can wash the packing in the storage space 203. And when the second vertical plate 901 moves, it will drive the cross plate 121 to move synchronously. After the cross plate 121 moves, it will drive the third vertical plate 122 and the fourth vertical plate 123 to move synchronously. During the movement of the third vertical plate 122 and the fourth vertical plate 123, the third tooth 124 and the fourth tooth 125 arranged thereon will successively contact the third gear 126 on the cross bar 111 and drive the third gear 126 to drive the deflector 112 to rotate, so that the exhaust gas flowing out of the storage space 203 can be evenly introduced to the spraying part of the spray pipe 101 for treatment; When the moving frame 504 moves downward under the action of the cam 503, it will drive the first vertical plate 601 and the second vertical plate 901 to move synchronously. When the first vertical plate 601 moves downward, the sliding rod 803 provided thereon will slide to the other side of the diamond-shaped groove 802, so as to drive the first vertical plate 601 to move on the moving frame 504, so that the first vertical plate 601 does not contact the first gear 604 during the downward movement. When the second vertical plate 901 moves downward, the second tooth 902 provided thereon will drive the second gear 903 to drive the threaded rod 401 to rotate in the reverse direction, so that the cleaning nozzle 402 moves in the reverse direction and resets. During this process, the cleaning nozzle 402 can still perform normal cleaning operations; When the cleaning nozzle 402 cleans the filler in the storage space 203 on one side, it can choose whether to open the inspection window 102 on the tower body 1 to choose whether to replace the filler in the storage space 203 on the other side. The specific operation can be selected according to the state of the filler.

[0042] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.
