Technical Field
[0001] The utility model belongs to the technical field of spray tower equipment, in particular to a spray tower equipment for waste gas treatment. Background Art
[0002] The spray tower equipment for waste gas treatment is an important waste gas treatment equipment, which is mainly used to remove harmful substances in waste gas, protect the environment and improve air quality. Its working principle is mainly to use solution to absorb and purify waste gas. When the waste gas passes through the spray tower, the spray liquid in the spray tower will spray and emulsify the waste gas, so that the particulate matter, organic matter and gaseous pollutants in the waste gas can be in close contact with the spray liquid. In this process, the pollutants will be absorbed and purified by the spray liquid, thereby achieving the purpose of eliminating harmful substances in the waste gas. Therefore, it can be seen that the existing spray tower equipment basically meets people's practical needs, but there are still the following problems.
[0003] When the operator uses the spray tower equipment for waste gas treatment to treat the waste gas, after the waste gas is discharged into the spray tower, the spray liquid sprayed in the spray tower contacts with the waste gas, thereby reacting with the harmful substances in the waste gas, thereby neutralizing the harmful substances. However, since dust or granular debris may remain in general waste gas, when the waste gas is sprayed, the dust or granular debris in the waste gas will be discharged with the liquid. Since the spray liquid needs to be reused, when the dust or granular debris is discharged with the liquid, the operator can spray and filter. For this reason, we propose a spray tower equipment for waste gas treatment. Utility Model Content
[0004] The utility model provides a spray tower device for waste gas treatment. After the liquid is filtered through a filter screen, the filtered liquid is discharged through a second support rod, and dust or granular debris enters a discharge pipe, so that the discharge pipe collects the dust or granular debris, thereby pre-treating the spray liquid and increasing the efficiency of spray liquid filtration.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spray tower device for waste gas treatment, comprising a spray tower body and a drain port, a drain port is fixed at the end of the spray tower body, and a filter shell is installed at the end of the drain port, a filter cavity is opened in the middle of the filter shell, and a avoidance groove is fixed on the inner wall of the filter cavity, a filter screen is fixed at the end of the avoidance groove, a drain pipe is fixed in the middle of the filter shell, and discharge pipes fixed on the filter shell are arranged at the ends of both sides of the drain pipe, and the discharge pipe is connected to the filter cavity, and a sealing cover is provided at the end of the discharge pipe.

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.
[0024] Example:
[0025] See also Figure 1 - Figure 6A spray tower device for waste gas treatment includes a spray tower body 1 and a drain port 2, the end of the spray tower body 1 is welded with the drain port 2, and the end of the drain port 2 is threadedly installed with a filter shell 3, the middle of the filter shell 3 is provided with a filter chamber 4, and the inner wall of the filter chamber 4 is welded with an avoidance groove 17, and the end of the avoidance groove 17 is threadedly installed with a filter screen 5, the middle of the filter shell 3 is welded with a drain pipe 11, and the ends of the drain pipe 11 are provided with discharge pipes 9 welded on the filter shell 3, and the discharge pipe 9 is connected with the filter chamber 4, and the discharge pipe 9 is connected with the filter chamber 4. The end thread sleeve is provided with a sealing cover 13, and the operator installs the filter shell 3 on the drain port 2, and aligns the filter chamber 4 opened in the middle of the filter shell 3 with the drain port 2. When the liquid in the spray tower body 1 contacts the exhaust gas poured into the spray tower body 1, the sprayed liquid reacts with the exhaust gas, and the reacted liquid enters the filter chamber 4 through the drain port 2. The liquid passes through the filter screen 5 installed on the avoidance groove 17 fixed on the inner wall of the filter chamber 4, so that the filter screen 5 filters the debris in the liquid. The filtered liquid passes through the filter screen 5 and enters the avoidance groove 17, and the liquid passing through the filter screen 5 is collected in the second support rod 12 through the avoidance groove 17, and is beaten out by the second support rod 12. Since the filter screen 5 is arranged in an arc shape, the blocked debris remains on the surface of the filter screen 5, and the liquid continuously beaten out through the discharge port 2 pushes the debris on the filter screen 5 to move, and pushes the debris into the discharge pipe 9, so that the discharge pipe 9 collects the debris. When the operator needs to perform When cleaning, the operator first twists the sealing cover 13 so that the internal thread opened on the inner wall of the sealing cover 13 and the thread opened at the opening of the discharge pipe 9 are threadedly matched with each other, so that the sealing cover 13 is rotated on the surface of the discharge pipe 9, and the sealing cover 13 is moved out from the surface of the discharge pipe 9. When the sealing cover 13 is moved out from the surface of the discharge pipe 9, the discharge pipe 9 is opened, and the debris in the discharge pipe 9 is discharged under the action of gravity, so that the operator can filter the debris and pre-treat the spray liquid after the spray treatment.
[0026] In other embodiments, the second support rod 12 is symmetrically welded to the inner wall of the drain pipe 11, and the middle part of the second support rod 12 is penetrated by the first push rod 7, a spring 21 is wound on the surface of the first push rod 7, and the two side ends of the spring 21 respectively abut between the surface of the second support rod 12 and the surface of the back plate 20 welded on the first push rod 7, a first pull plate 19 is welded to the end of one side of the first push rod 7, and a push plate 6 that fits with the filter screen 5 is welded to the other end of the first push rod 7. When the filter screen 5 is used for a long time and the operator needs to clean the debris accumulated on the surface of the filter screen 5, the operator first opens the drain pipe 11, and then the operator pulls the first pull plate 19. When the operator pulls the first pull plate 19 to move, the first pull plate 19 drives the first push rod 7 to slide in the second support rod 12, and when the first push rod 7 moves, the first push rod 7 drives the back plate 20 to move, and when the back plate 20 moves, the back plate 20 squeezes the spring 21. After the spring 21 is elastically deformed, the spring 21 avoids the push plate 20. When the first push rod 7 moves, the first push rod 7 drives the push plate 6 to move, so that the push plate 6 is separated from the filter screen 5. When the push plate 6 is separated from the filter screen 5, the operator releases the first pull plate 19 again. After the first pull plate 19 makes the push plate 20 no longer press the spring 21, the elastic deformation of the spring 21 is restored, and the spring 21 pushes the push plate 20 to move, so that the push plate 20 drives the first push rod 7 to move, and the first push rod 7 drives the push plate 6 to move. Due to the push generated by the elastic deformation recovery of the spring 21, the first push rod 7 drives the push plate 6 to move. After the push plate 6 moves to the surface of the filter screen 5, the push plate 6 hits the surface of the filter screen 5, causing the surface of the filter screen 5 to vibrate. When the surface of the filter screen 5 vibrates, the debris attached to the surface of the filter screen 5 shakes, causing the debris to slide from the surface of the filter screen 5 and slide into the discharge pipe 9.
[0027] In other embodiments, a guide ring 18 is sleeved on the surface of the first push rod 7, and the guide ring 18 is welded to the second support rod 12. When the operator pulls the first push rod 7 to move inside the second support rod 12, it is fixed on the surface of the second support rod 12 by the guide ring 18, and the guide ring 18 is sleeved on the surface of the first push rod 7, so that the guide ring 18 increases the contact area of the first push rod 7 passing through one side of the second support rod 12, so that the first push rod 7 can slide stably inside the second support rod 12.
[0028] In other embodiments, the push plate 6 is configured as an arc-shaped plate, and the arc-shaped plate configured for the push plate 6 matches the filter screen 5. By matching the arc-shaped plate configured for the push plate 6 and the filter screen 5, the surface of the push plate 6 can fit the inner wall of the filter screen 5, thereby improving the stability of the push plate 6 in pushing the filter screen 5.
[0029] In other embodiments, a first support rod 10 is welded to the inner wall of the discharge pipe 9, and a second push rod 14 is passed through the middle of the first support rod 10, a fixing rod 15 is welded to the end of the second push rod 14, and a scraper ring 16 that fits on the inner wall of the discharge pipe 9 is fixed to the surface of the fixing rod 15, and a second pull plate 22 is welded to the end of the second push rod 14 away from the fixing rod 15. When the operator pulls the second pull plate 22 to move, the second pull plate 22 pulls the second push rod 14 to move, and the second push rod 14 slides in the first support rod 10, and the second push rod 14 pulls the fixing rod 15 to move, and the fixing rod 15 drives the scraper ring 16 to move. When the scraper ring 16 moves, the scraper ring 16 scrapes the inner wall of the discharge pipe 9, so that the fixing rod 15 and the scraper ring 16 push the debris remaining in the discharge pipe 9 to prevent the debris from being unable to be discharged from the discharge pipe 9 under the action of weight.
[0030] In other embodiments, the first support rod 10 is penetrated by the second push rod 14 and is welded with a spring 21, and the spring 21 is sleeved on the surface of the second push rod 14. After the spring 21 is sleeved on the surface of the second push rod 14, the spring 21 increases the contact area between the second push rod 14 and the first support rod 10, thereby improving the stability of the movement of the second push rod 14.
[0031] In other embodiments, a traction ring 8 is fixed inside the avoidance groove 17, and the traction ring 8 is configured to have an inclined slope.
[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
