[0003] The spray system in the existing spray tower usually adopts fixed installation, and the liquid injection angle is fixed, to cause that waste gas and absorption liquid do not contact comprehensively in the gas-liquid mixing process, so that waste gas treatment purification effect is poor, and finally discharged waste gas cannot meet the discharge standard. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problems in the prior art, and provides a waste gas spray tower equipment for waste gas treatment.

[0005] The technical scheme adopted to solve the above technical problems is as follows: a waste gas spray tower equipment for waste gas treatment is provided, which comprises a shell main body, the shell main body is provided with a spray pipeline at the top end, the two ends of the spray pipeline are an inlet end and a closed end respectively, the two ends of the spray pipeline are rotatably connected with the side wall of the shell main body, a swing mechanism is arranged on one side of the closed end of the spray pipeline, an air inlet pipeline is arranged at the bottom of the shell main body, the air inlet pipeline is arranged in communication with the shell main body, and an air inlet adjusting mechanism is arranged outside the air inlet pipeline.

[0006] Through the above technical scheme, the spray pipeline is driven by the swing mechanism to be regularly swung and uniformly sprayed, the problem of incomplete coverage of liquid spraying angle caused by fixed installation of the traditional spraying system is solved, the gas-liquid mixing efficiency is improved, the air inlet amount of the air inlet pipeline is controlled by arranging the air inlet adjusting mechanism, the air inlet amount can be matched with the spraying liquid amount by adjusting the air inlet amount, the best gas-liquid ratio is achieved, and the final treatment effect is improved.

[0007] Further, the spray pipeline is provided with nozzles in communication at the bottom, and the nozzles are arranged and distributed in sequence along the bottom wall of the spray pipeline.

[0008] Through the above technical scheme, the liquid medicine is uniformly sprayed out by the nozzles of the spray pipeline, and the spray pipeline is regularly rotated under the driving of the swing mechanism, so that the coverage area of the sprayed liquid is wider, the gas-liquid contact is more sufficient, and the purification treatment of waste gas is more thorough.

[0009] Furthermore, the swing mechanism includes a gear, which is fixedly connected to the closed end of the spray pipe. A sector plate is provided at the bottom end of the gear, and a movable rack is slidably connected to the top wall of the sector plate. The movable rack meshes with the gear, and a support shaft is fixedly connected to the bottom end of the sector plate. The support shaft is rotatably connected to the side wall of the outer shell.

[0010] With the above technical solution, the fan-shaped plate rotates around the support shaft, and the movable rack at the top drives the gear to rotate, which in turn drives the spray pipe to rotate.

[0011] Furthermore, the side wall of the sector plate is provided with a through groove, and a limiting member is slidably connected in the through groove. A second connecting rod is rotatably connected to the outer wall of the limiting member. A first connecting rod is rotatably connected to the end of the second connecting rod away from the limiting member. A motor is provided on one side of the first connecting rod, and the output end of the motor is fixedly connected to the side wall of the first connecting rod.

[0012] Furthermore, the limiting component includes a limiting post that penetrates the side wall of the second connecting rod, and a limiting nut is movably connected to the outer wall of the limiting post.

[0013] With the above technical solution, after the motor starts, it drives the second connecting rod to move through the first connecting rod. Then, through the rotational connection between the second connecting rod and the limiting post, the sector plate begins to rotate around the support shaft. By adjusting the positional relationship between the limiting post and the through slot, the rotation amplitude of the sector plate can be changed. When the distance between the limiting post and the support shaft is larger, the rotation amplitude of the sector plate is larger; when the distance between the limiting post and the support shaft is smaller, the rotation amplitude of the sector plate is smaller. According to the change in the rotation amplitude of the sector plate, the swing angle of the spray pipe can be changed, thereby avoiding the problem of insufficient angle coverage caused by fixed installation of the spray system and fixed angle spraying of liquid.

[0014] Furthermore, the intake adjustment mechanism includes a rotating shaft, with both ends of the rotating shaft rotatably connected to the intake pipe, and fan blades fixedly connected to both sides of the axis of the rotating shaft, the sidewalls of the fan blades corresponding to the inner wall of the intake pipe.

A support plate is provided on the side of the push-pull plate away from the rotating shaft. A limiting groove is formed on the side wall of the support plate. The limiting groove is slidably connected to the push-pull plate. An electric telescopic rod is arranged parallel to one side of the limiting groove. The output end of the electric telescopic rod is fixedly connected to the side wall of the push-pull plate.

[0016] Through the above technical solution, the output end of the electric telescopic rod drives the push-pull plate to move linearly along the limiting groove. Through the engagement connection between the push-pull plate and the limiting rod, the rotating shaft rotates under the drive of the limiting rod. Then, the fan blades follow the rotation of the rotating shaft to open and close, and the opening and closing angle can also be adjusted according to actual production needs.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention uses a swing mechanism to drive the spray pipe, which swings regularly to spray evenly. This solves the problem of incomplete liquid spray angle coverage caused by fixed installation in traditional spray systems, thus improving gas-liquid mixing efficiency. A first connecting rod drives a second connecting rod, and the rotational connection between the second connecting rod and the limiting post enables the rotation of the sector plate. By adjusting the positional relationship between the limiting post and the through groove, the rotation amplitude of the sector plate is varied. This variation in the sector plate's rotation amplitude changes the swing amplitude of the spray pipe, further enhancing the coverage of the liquid spray angle. An air intake adjustment mechanism controls the air intake volume of the air intake pipe, allowing it to match the spray liquid volume for an optimal gas-liquid ratio and improved final treatment effect. An electric telescopic rod output drives a push-pull plate to move linearly along the limiting groove. The engagement between the push-pull plate and the limiting rod causes the rotating shaft to rotate, which in turn allows the fan blades to adjust their angle. Attached Figure Description

[0025] like Figure 1 - Figure 4 As shown, a waste gas spray tower device for waste gas treatment includes a shell body 1, a spray pipe 6 is provided at the top of the shell body 1, the two ends of the spray pipe 6 are a water inlet end and a closed end respectively, the two ends of the spray pipe 6 are rotatably connected to the side wall of the shell body 1 respectively, a swing mechanism 3 is provided on one side of the closed end of the spray pipe 6, an air inlet pipe 5 is provided at the bottom of the shell body 1, the air inlet pipe 5 is connected to the shell body 1, and an air inlet regulating mechanism 4 is provided on the outside of the air inlet pipe 5.

[0026] The bottom of the spray pipe 6 is connected to a nozzle 7, which is arranged sequentially along the bottom wall of the spray pipe 6. The spray pipe 6 sprays the liquid medicine evenly through the nozzle 7. Under the drive of the swing mechanism 3, the spray pipe 6 rotates regularly, thereby making the coverage area of ​​the sprayed liquid wider, so as to make the gas-liquid contact more sufficient and the final purification treatment of the exhaust gas more thorough.

[0027] The swing mechanism 3 includes a gear 309, which is fixedly connected to the closed end of the spray pipe 6. A sector plate 301 is provided at the bottom end of the gear 309. A movable rack 308 is slidably connected to the top wall of the sector plate 301. The movable rack 308 meshes with the gear 309. A support shaft 310 is fixedly connected to the bottom end of the sector plate 301. The support shaft 310 is rotatably connected to the side wall of the outer shell 1. When the sector plate 301 rotates around the support shaft 310, it drives the gear 309 to rotate through the movable rack 308 at the top end. The rotation of the gear 309 drives the spray pipe 6 to rotate.

[0028] The side wall of the fan-shaped plate 301 is provided with a through groove 302. A limiting member is slidably connected in the through groove 302. A second connecting rod 303 is rotatably connected to the outer wall of the limiting member. A first connecting rod 304 is rotatably connected to the end of the second connecting rod 303 away from the limiting member. A motor 311 is provided on one side of the first connecting rod 304. The output end of the motor 311 is fixedly connected to the side wall of the first connecting rod 304.

[0029] The limiting component includes a limiting post 305, which penetrates the side wall of the second connecting rod 303, and a limiting nut 306 is movably connected to the outer wall of the limiting post 305.

[0030] After the motor 311 starts, it drives the second connecting rod 303 to move through the first connecting rod 304. Then, through the rotational connection between the second connecting rod 303 and the limiting post 305, the sector plate 301 begins to rotate around the support shaft 310. By adjusting the positional relationship between the limiting post 305 and the through groove 302, the rotation amplitude of the sector plate 301 is changed. When the distance between the limiting post 305 and the support shaft 310 is larger, the rotation amplitude of the sector plate 301 is larger. When the distance between the limiting post 305 and the support shaft 310 is smaller, the rotation amplitude of the sector plate 301 is smaller. According to the change of the rotation amplitude of the sector plate 301, the swing angle of the spray pipe 6 is changed, thereby avoiding the problem of insufficient angle coverage caused by the fixed installation of the spray system and the fixed angle of liquid spraying.

[0031] The intake regulating mechanism 4 includes a rotating shaft 404, with both ends of the rotating shaft 404 rotatably connected to the intake pipe 5. Fan blades 403 are fixedly connected to both sides of the axis of the rotating shaft 404, and the sidewalls of the fan blades 403 correspond to the inner wall of the intake pipe 5.

A support plate 401 is provided on the side of the push-pull plate 407 away from the rotating shaft 404. A limiting groove 402 is provided on the side wall of the support plate 401. The limiting groove 402 is slidably connected to the push-pull plate 407. An electric telescopic rod 406 is arranged parallel to one side of the limiting groove 402. The output end of the electric telescopic rod 406 is fixedly connected to the side wall of the push-pull plate 407.

[0033] The output end of the electric telescopic rod 406 drives the push-pull plate 407 to move linearly along the limiting groove 402. Through the engagement connection between the push-pull plate 407 and the limiting rod 405, the rotating shaft 404 rotates under the drive of the limiting rod 405. As a result, the fan blade 403 opens and closes following the rotation of the rotating shaft 404. The opening and closing angle can also be adjusted according to actual production needs.

[0034] In use, the motor 311 is first started, which drives the second connecting rod 303 to move via the first connecting rod 304. Then, through the rotational connection between the second connecting rod 303 and the limiting post 305, the fan-shaped plate 301 begins to rotate around the support shaft 310. By adjusting the positional relationship between the limiting post 305 and the through slot 302, the rotation amplitude of the fan-shaped plate 301 is changed. The electric telescopic rod 406 is started, and through the output end of the electric telescopic rod 406, the push-pull plate 407 moves linearly along the limiting groove 402. Through the engagement connection between the push-pull plate 407 and the limiting rod 405, the rotating shaft 404 rotates under the drive of the limiting rod 405. Thus, the fan blade 403 follows the rotation of the rotating shaft 404 to open and close, and the opening and closing angle can also be adjusted according to actual production needs.
