Abstract
Description
Technical Field
[0001] The utility model relates to waste gas spray tower equipment for waste gas treatment, belonging to the technical field of spray towers. Background Art
[0002] The spray tower exists as a treatment equipment for environmental waste gas treatment. Its working principle is that when dust-containing waste gas or oil-containing waste gas passes through the spray tower body, liquid medium is sprayed out from the appropriate position inside the tower body. Some are alkali solution and some are sulfuric acid solution. If the waste gas contains acid, alkali solution spraying is selected to neutralize the acid. If the waste gas contains alkaline, sulfuric acid solution is selected to absorb. The specific selection of acid and alkali solution depends on the nature of the waste gas and the company's own situation. Waste gas without acid or alkali but containing oil and dust can be treated by spraying with circulating water solution. When the waste gas enters from the bottom of the tower body, it comes into contact with the spray medium sprayed from the spray tower. After contact, the waste gas or oil is wrapped by water droplets. The water droplets wrapped with pollutants collide again, the surface area increases and the gravity increases. When the gravity increases, the water droplets wrapped with pollutants fall to the bottom of the spray tower under the influence of gravity. 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] When the existing spray tower sprays exhaust gas, the water flow after spraying the exhaust gas is easily contaminated by the exhaust gas, making the contaminated water flow easy to adhere to the inside of the tower body and difficult to clean. At the same time, the filling filter in the spray tower is installed inside the spray tower and is not easy to replace. Over time, the filling filter in the tower will gradually deteriorate in filtering toxic and harmful gases, thereby causing the company's emissions to fail to meet standards and cause environmental damage.

[0025] See also Figure 1-Figure 6 As shown, a waste gas spray tower device for waste gas treatment includes a spray tower body 1, a fixed ring 4, a waste gas inlet pipe 7, a mounting frame 5 and a fixing frame 6, and also includes a filling layer convenient replacement component 2 and a tower cleaning component 3. One end of the mounting frame 5 is fixedly connected to the outer surface of the fixed ring 4, and the inner wall of the fixed ring 4 is fixedly installed on the outer surface of the spray tower body 1. Both sides of the fixing frame 6 are fixedly connected to the mounting frame 5. One end of the waste gas inlet pipe 7 passes through the interior of the fixing frame 6 and communicates with the interior of the spray tower body 1. The filling layer convenient replacement component 2 is arranged at the lower part of the spray tower body 1, and the tower cleaning component 3 is arranged inside the spray tower body 1. The arranged filling layer convenient replacement component 2 can conveniently replace the filler, so that the filtering effect is better. At the same time, the arranged tower cleaning component 3 can clean the inner wall of the spray tower, reduce the accumulation of impurities on the inner wall, and make the tower cleaner.
[0026] like Figure 2-Figure 3As shown, the filling layer convenient replacement component 2 includes a screw rod 201 and a conical head 202, the conical head 202, one end of the screw rod 201 is rotatably connected to the inside of the mounting frame 5, the outer surface of the screw rod 201 is screwed with a lifting plate 203, one end of the lifting plate 203 is fixedly connected to the outer surface of the conical head 202, a motor 204 is fixedly installed on the upper part of the mounting frame 5, the output of the motor 204 passes through the upper part of the mounting frame 5 and is fixedly connected to one end of the screw rod 201, a filter screen 205 is fixedly installed inside the conical head 202, and a connecting rod body 206 is fixedly installed on the upper part of the filter screen 205. The filling layer convenient replacement component 2 also includes a circular plate 2 for placing 07, a circular support plate 208 is fixedly installed on the outer surface of the connecting rod body 206, a screw 209 is installed between the circular support plate 208 and the placing circular plate 207, a solenoid valve 210 is fixedly installed at the lower part of the filter 205, a rod body 211 is fixedly installed at the lower part of the mounting frame 5, and the inner part of the lifting plate 203 slides on the outer surface of the rod body 211. The user connects the exhaust pipe to the exhaust gas inlet pipe 7, and then connects the pressurized water pump 307 to the water source. The pressurized water pump 307 is used to flush water in the water pipe 305, and finally sprays and discharges the water through the sprinkler head 306. As the gas floats upward, the gas filter set in the circular support plate 208 The filler performs the initial filtration of toxic and harmful gases, and the spray head 306 is provided to spray and disinfect the gases, etc. After the filtration and spraying are completed, the accumulated water inside the spray tower body 1 can be discharged by opening the solenoid valve 210, and the top of the spray tower body 1 can be connected to a pipeline to discharge the filtered gas. When the filter filler needs to be replaced, the motor 204 is turned on to drive the screw rod 201 to rotate, and the rotation of the screw rod 201 drives the lifting plate 203 to move, and the movement of the lifting plate 203 can drive the conical head 202 to move downward, and the movement of the conical head 202 drives the filter 205 to move, and the movement of the filter 205 drives the connection The rod body 206 moves, and the connecting rod body 206 moves so that the circular support plate 208 is moved out of the spray tower body 1. When the circular support plate 208 is moved out of the spray tower body 1, the user can complete the replacement by placing a new filter filler on the circular support plate 208. The replacement can be completed by starting the motor 204 again to drive the conical head 202 to reset. At the same time, a small hole is opened between the inner and outer walls of the circular support plate 208. The small hole can facilitate the outflow of water. Replacing in the above manner can avoid the filling filter in the spray tower. It is not easy to replace the filling filter in the spray tower. Over time, it will cause the filling filter in the tower to gradually deteriorate in filtering toxic and harmful gases.
[0027] like Figure 4-Figure 6As shown, the cleaning assembly 3 in the tower includes a moving ring 301, and a notch begins to appear on the outer surface of the moving ring 301. A threaded rod 302 is rotatably connected inside the spray tower body 1. The moving ring 301 is screwed on the outer surface of the threaded rod 302. A plate 303 is fixedly installed on the top of the spray tower body 1. A stepper motor 304 is fixedly installed on the upper part of the plate 303.

A pressurized water pump 307 is fixedly installed on the upper part of the fixed frame 6. A water pipe 305 is fixedly installed between the water outlet of the pressurized water pump 307 and the inside of the spray tower body 1. One end of the water pipe 305 is fixed inside the spray tower body 1. A spray head 306 is fixedly installed. When the spray tower body 1 is frequently used and the inner wall needs to be cleaned, the stepper motor 304 is turned on to drive the threaded rod 302 to rotate. The rotation of the threaded rod 302 causes the movable ring 301 to slide on the inner wall of the spray tower body 1, so that the movable ring 301 can move and clean the inner wall of the spray tower body 1. The impurities after cleaning will fall on the circular support plate 208, and then the motor 204 will complete the cleaning of the fallen impurities, so that the inner wall of the spray tower body 1 is cleaner and the air filtering effect is better, thereby alleviating the problem that when the spray tower is spraying exhaust gas, the water flow after spraying the exhaust gas is easily contaminated by the exhaust gas, making the contaminated water flow easy to adhere to the inside of the tower body and difficult to clean.
[0028] When the utility model is in use, the user connects the exhaust pipe to the exhaust gas inlet pipe 7, and then connects the pressurized water pump 307 to the water source. The water pipe 305 is filled with water through the pressurization of the pressurized water pump 307, and finally the water is sprayed and discharged through the spray head 306. As the gas floats upward, the gas filter filler arranged in the circular support plate 208 performs the initial filtration on the toxic and harmful gas, and the spray head 306 sprays and disinfects the gas, etc. After the filtering and spraying are completed, the accumulated water inside the spray tower body 1 can be discharged by opening the solenoid valve 210, and the top of the spray tower body 1 can be connected to a pipeline to discharge the filtered gas. When the filter filler needs to be replaced, the motor 204 is turned on to drive the screw rod 201 to rotate, and the rotation of the screw rod 201 drives the lifting plate 203 to move. The movement of the lifting plate 203 can drive the conical head 202 to move downward, the movement of the conical head 202 drives the filter 205 to move, the movement of the filter 205 drives the connecting rod 206 to move, and the movement of the connecting rod 206 makes the circular support plate 208 move out of the spray tower body 1. When the circular support plate 208 is moved out of the spray tower body 1, the user can complete the replacement by placing a new filter filler on the circular support plate 208. The replacement can be completed by starting the motor 204 again to drive the conical head 202 to reset. At the same time, a small hole is opened between the inner and outer walls of the circular support plate 208. The small hole is arranged to facilitate the outflow of water. Replacing in the above manner can avoid the filling filter in the spray tower. It is not easy to replace the filling filter installed inside the spray tower. Over time, it will cause the filling filter in the tower to gradually deteriorate in filtering toxic and harmful gases.
