Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a spray tower that facilitates the cleaning and treatment of waste gas. Background Technology

[0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before its external emission to meet national emission standards. General waste gas treatment includes the treatment of organic waste gas, dust waste gas, acid and alkali waste gas, odor waste gas, and air sterilization and purification. For treating acid mist waste gas, a spray tower is used. The acid mist waste gas is introduced into the purification tower through a duct, passes through a packing layer, and undergoes a thorough gas-liquid two-phase contact absorption and neutralization reaction with sodium hydroxide absorbent. After purification, the acid mist waste gas is dehydrated and demisted by a demister plate before being discharged into the atmosphere by a fan.

[0003] Patent document CN219539835U discloses a spray device for waste gas treatment, including: a water tank, a spray tower on the outer wall of the top center of the water tank, a treatment box on the outer wall of the top center of the spray tower, and several through holes at the bottom of the spray tower. By setting a sliding block, the sliding block rotates up and down with the rotation of the worm gear, so that the cleaning block can clean the inner wall of the spray tower. The rotation of the worm gear can drive the spray head to rotate, so as to fully reduce dust in the waste gas and facilitate further treatment of the waste gas. By setting a nano-photocatalytic filter and an activated carbon filter, the waste gas can be adsorbed, decomposed and disinfected, thereby improving the treatment effect of the waste gas.

[0004] Although the aforementioned application documents describe how setting up nano-photocatalytic filters and activated carbon filters can adsorb, decompose, and disinfect waste gas, thus improving the treatment effect, the demister plate will become clogged by impurities in the water after prolonged use, preventing the waste gas inside the spray tower from being discharged.

[0005] Therefore, a spray tower that facilitates the cleaning and treatment of waste gas is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a spray tower that facilitates the cleaning and treatment of waste gas, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a spray tower body is included, a demister plate is mounted on the top of the spray tower body, and a cleaning device for cleaning the demister plate is mounted on the top of the spray tower body.

[0008] The cleaning device includes a first rotating rod, which is rotatably connected to the inner wall of the spray tower body via a bearing. A second rotating rod is rotatably connected to the top of the demister plate via a bearing. A telescopic cleaning block is fixedly sleeved on the outer wall of the second rotating rod. A scraping block is fixedly connected to the front of the telescopic cleaning block. A conical block is fixedly connected to the inner wall of the spray tower body. Two vertical plates are fixedly connected to the top of the telescopic cleaning block. Elastic telescopic rods are fixedly connected to the sides of the two vertical plates. A motor is mounted on the side of the spray tower body. A transmission assembly for driving the motor and the telescopic cleaning block is mounted on the top of the spray tower body.

[0009] Preferably, the transmission assembly includes a first bevel gear, which is fixedly connected to the side of the first rotating rod, and a second bevel gear is fixedly connected to the top of the second rotating rod. The first bevel gear and the second bevel gear mesh with each other. The first rotating rod extends to the right side through the spray tower body, and the extended end of the first rotating rod is fixedly connected to the output end of the motor.

[0010] Preferably, the telescopic cleaning block consists of a thick cleaning block and a thin cleaning block, with the thin cleaning block slidably connected to the inner wall of the thick cleaning block.

[0011] Preferably, the telescopic cleaning block has a chamfer on its side.

[0012] Preferably, the top of the spray tower body is equipped with a tapping device to prevent impurities from adhering to the top of the telescopic cleaning block.

[0013] Preferably, the striking device includes a hydraulic chamber, which is fixedly connected to the top of the vertical plate. A hydraulic rod is slidably connected to a piston at one end inside the hydraulic chamber, and the hydraulic rod is fixedly connected to the top of the telescopic cleaning block.

[0014] Preferably, a rack is slidably connected to a piston at one end inside the hydraulic chamber, a fixed plate is fixedly connected to the top of the telescopic cleaning block, a third rotating rod is rotatably connected to the front of the fixed plate via a bearing, a circular gear is fixedly sleeved on the outer wall of the third rotating rod, a striking block is fixedly sleeved on the outer wall of the third rotating rod, and the rack and the circular gear mesh with each other.

[0015] Compared with the prior art, this utility model provides a spray tower that facilitates the cleaning and treatment of waste gas, and has the following beneficial effects:

[0016] 1. Driven by a motor, the telescopic cleaning block and scraper block can move left and right while rotating, effectively cleaning the top of the demister plate and solving the problem of exhaust gas not being able to escape due to impurities clogging the demister plate. Through the cooperation of the telescopic cleaning block and the conical block, and the resetting action of the elastic telescopic rod, the cutting action of the telescopic cleaning block and scraper block is achieved, thereby improving the cleaning effect and ensuring the normal discharge of exhaust gas inside the spray tower.

[0017] Second, when the telescopic cleaning block extends or retracts, it drives a series of components such as hydraulic rods, racks, spur gears, and third rotating rods to work together, ultimately causing the striking block to strike the top of the telescopic cleaning block. The vibration generated by the striking can dislodge the impurities adhering to the telescopic cleaning block, further enhancing the cleaning effect, preventing impurities from accumulating on the telescopic cleaning block, and ensuring the continuous effectiveness of the cleaning device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] See Figures 1-4This embodiment provides a spray tower for easy cleaning and treatment of exhaust gas, including a spray tower body 1, a demister plate 4 mounted on the top of the spray tower body 1, and a cleaning device 2 for cleaning the demister plate 4 mounted on the top of the spray tower body 1.

[0026] The cleaning device 2 includes a first rotating rod 22, which is rotatably connected to the inner wall of the spray tower body 1 via a bearing. A second rotating rod 25 is rotatably connected to the top of the demisting plate 4 via a bearing. A telescopic cleaning block 26 is fixedly sleeved on the outer wall of the second rotating rod 25. A scraping block 28 is fixedly connected to the front of the telescopic cleaning block 26. A conical block 27 is fixedly connected to the inner wall of the spray tower body 1. Two vertical plates 29 are fixedly connected to the top of the telescopic cleaning block 26. Elastic telescopic rods 210 are fixedly connected to the sides of the two vertical plates 29. A motor 21 is mounted on the side of the spray tower body 1. A transmission assembly for driving the motor 21 and the telescopic cleaning block 26 is mounted on the top of the spray tower body 1.

[0027] The transmission assembly includes a first bevel gear 23, which is fixedly connected to the side of the first rotating rod 22. A second bevel gear 24 is fixedly connected to the top of the second rotating rod 25. The first bevel gear 23 and the second bevel gear 24 mesh with each other. The first rotating rod 22 extends to the right side through the spray tower body 1. The extended end of the first rotating rod 22 is fixedly connected to the output end of the motor 21.

[0028] The telescopic cleaning block 26 consists of a thick cleaning block and a thin cleaning block, with the thin cleaning block slidably connected to the inner wall of the thick cleaning block. The telescopic cleaning block 26 has chamfers on its side.

[0029] In practical use, the above-mentioned equipment is activated by starting motor 21. The output of motor 21 drives the first rotating rod 22 to rotate, which in turn drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the second bevel gear 24 to rotate, which in turn drives the second rotating rod 25 to rotate. The second rotating rod 25 drives the telescopic cleaning block 26 to rotate, which in turn drives the scraping block 28 to rotate, thus cleaning the top of the demisting plate 4. At the same time, when the telescopic cleaning block 26 comes into contact with the conical block 27, the conical block 27 will squeeze the telescopic cleaning block 26. While the telescopic cleaning block 26 is being squeezed, the elastic telescopic rod 210 is also being squeezed. When the conical block 27 no longer limits the telescopic cleaning block 26, the elastic telescopic rod 210 drives the telescopic cleaning block 26 to reset. This allows the telescopic cleaning block 26 and the scraping block 28 to move left and right while rotating, achieving a cutting action and further improving the cleaning effect.

[0030] Example 2

[0031] See Figures 1-4 Based on Example 1, the top of the spray tower body 1 is equipped with a knocking device 3 to prevent impurities from adhering to the top of the telescopic cleaning block 26.

[0032] The striking device 3 includes a hydraulic chamber 31, which is fixedly connected to the top of the vertical plate 29. A hydraulic rod 32 is slidably connected to one end of the hydraulic chamber 31 by a piston, and the hydraulic rod 32 is fixedly connected to the top of the telescopic cleaning block 26.

[0033] Inside the hydraulic chamber 31, a piston at one end is slidably connected to a rack 33. A fixed plate 34 is fixedly connected to the top of the telescopic cleaning block 26. A third rotating rod 35 is rotatably connected to the front of the fixed plate 34 via a bearing. A spherical gear 36 is fixedly sleeved on the outer wall of the third rotating rod 35. A striking block 37 is fixedly sleeved on the outer wall of the third rotating rod 35. The rack 33 and the spherical gear 36 mesh with each other.

[0034] When the above-mentioned equipment is used, the telescopic cleaning block 26 extends and retracts, causing the hydraulic rod 32 to move to the left. During the process of the hydraulic rod 32 moving to the left, the rack 33 moves to the left. The rack 33 drives the sprocket 36 to rotate, the sprocket 36 drives the third rotating rod 35 to rotate, and the third rotating rod 35 drives the striking block 37 to rotate, striking the top of the telescopic cleaning block 26. The vibration generated by the striking causes the impurities adhering to the telescopic cleaning block 26 to fall off.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
