Technical Field
[0001] This utility model relates to the field of waste gas purification tower technology, specifically to a chemical waste gas purification tower for safe chemical production. Background Technology
[0002] Chemical waste gas refers to the toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste gas often contains a wide variety of pollutants with complex physical and chemical properties and varying degrees of toxicity, seriously polluting the environment and affecting human health.
[0003] A patent with publication number CN222694340U discloses a chemical waste gas purification tower for chemical safety production. Its background technology addresses the problem that "existing waste gas purification towers cannot recycle and purify the water after spraying during use, resulting in a significant waste of water resources. Furthermore, the residue generated during waste gas purification is difficult to clean, and excessive accumulation can affect the tower's operation." The proposed solution addresses this problem by including a tower body with an inlet on its side, a water tank installed on one side of the tower body, the water tank connected to the tower body via a connecting pipe, a filter screen installed at the bottom of the spray nozzle, and a cleaning component installed at the bottom of the filter screen."
[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: it cleans the impurities and waste particles on the filter screen by rotating the scraper, but since the filter screen is placed horizontally and fixedly, the impurities and waste particles will enter the filter holes during the process of the scraper rotating and cleaning. This not only makes it difficult to clean the impurities and waste particles, but also easily causes blockage inside the filter screen, resulting in poor cleaning effect and thus reducing the efficiency and effect of water resource recycling.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1
[0030] Please see Figure 1 - Figure 5 The present invention provides a chemical waste gas purification tower for safe chemical production, comprising: a base 1, a main box 2 fixedly installed on one side of its top, and a tower body 3 fixedly installed on the top of the main box 2. The tower body 3 is provided with a spraying mechanism inside, wherein an air inlet pipe is installed on the tower body 3, and the inner bottom wall of the main box 2 is inclined.
[0031] A water tank 4 is fixedly installed on the other side of the top of the base 1. A connecting pipe 5 is fixedly installed between the water tank 4 and the main tank 2. The connecting pipe 5 is equipped with a one-way valve, which allows water in the main tank 2 to flow into the water tank 4. A purification device (existing technology disclosed in the art) is installed on the connecting pipe 5 to facilitate the filtration and purification of the recycled wastewater. In addition, a water inlet pipe is installed on one side of the water tank 4 to facilitate the addition of water.
[0032] A rotating shaft 6 is rotatably connected between the two sides of the inner wall of the main housing 2, and a power mechanism for driving the rotating shaft 6 is provided inside the main housing 2;
[0033] A movable frame 7 is fixedly installed on the surface of the rotating shaft 6, and grooves are provided on both sides of the inner wall of the movable frame 7;
[0034] The filter screen 8 is located inside the groove and is shaken by a vibration mechanism on the movable frame 7.
[0035] Collection shell 9 is fixedly installed on the bottom wall inside the main body 2;
[0036] And a discharge shell 10 fixedly installed on one side of the collection shell 9 and extending out of the main box 2, with a sealing plate at the end of the discharge shell 10.
[0037] The power mechanism includes a worm gear 13 fixedly installed at the center of the surface of the rotating shaft 6, a motor 11 fixedly installed on the top wall inside the main housing 2, and a worm 12 fixedly connected to the output end of the motor 11 and meshing with the worm gear 13.
[0038] The vibration mechanism includes multiple sets of springs 14 fixedly installed on the upper and lower sides of the filter screen 8, and multiple miniature vibrators 15 fixedly installed on one side of the top of the filter screen 8.
[0039] The technical solution provided in this embodiment is as follows: During use, the exhaust gas enters the tower body 3 and is purified by spraying through the spraying mechanism and water tank 4. The impurities and wastewater generated by the spraying and purification fall into the main housing 2 and land on the surface of the filter screen 8. At this time, the filter screen 8 is in a horizontal state and is kept stable by the self-locking properties of the worm gear 13 and worm 12. The wastewater and impurities are filtered and separated by the filter screen 8. The wastewater is returned to the water tank 4 after being treated by the connecting pipe 5 and the purification device for recycling and reducing waste. The filtered impurities remain on the surface of the filter screen 8. During cleaning, the motor 11 drives the worm 12 to rotate, causing the worm 12 to mesh with the worm gear 13 and drive the rotating shaft 6 to rotate downward. The movable frame 7 is tilted so that one end of the movable frame 7 is attached to the collection shell 9. At this time, the filter screen 8 is tilted, and the micro vibrator 15 and the spring 14 make the filter screen 8 vibrate inside the movable frame 7. This allows the impurity particles on the surface of the filter screen 8 to be shaken off along the inclined surface and collected in the collection shell 9. After the purification work is completed, the sealing cover at the end of the discharge shell 10 can be opened to discharge the impurities collected in the collection shell 9. Therefore, the impurities on the surface of the filter screen 8 are effectively cleaned, avoiding the poor cleaning effect of the scraper, which makes it easy for impurities to enter the filter holes and cause blockage. This ensures the effect of spray wastewater separation and effectively improves the effect and efficiency of spray water resource recovery.
[0040] Furthermore, the spraying mechanism includes a sprayer 16 disposed inside the tower body 3, a pump body 17 fixedly installed on one side of the top of the water tank 4, a discharge pipe 18 fixedly installed on the top of the tower body 3, and a filter cylinder 19 detachably installed at the end of the discharge pipe 18.
[0041] The filter cartridge 19 is equipped with a filter element inside. The output end of the pump body 17 extends through pipe one to the inside of the tower body 3 and is connected to the sprayer 16. The input end of the pump body 17 extends through pipe two to the inside of the water tank 4. The filter element can be an activated carbon filter element or other filter elements for purifying and filtering waste gas.
[0042] Specifically, after the exhaust gas enters the tower body 3, water is drawn from the water tank 4 by the pump body 17 and sent to the sprayer 16 for spraying. This allows the sprayed purified liquid to come into contact with the exhaust gas for purification. The purified gas enters the filter cartridge 19 through the discharge pipe 18 and undergoes further purification and filtration through the filter element inside the filter cartridge 19. Finally, it is discharged from the through holes on the surface of the filter cartridge 19. The purified impurities and wastewater fall onto the filter screen 8 for filtration, so that the water resources can be recycled and reused in the future, reducing the waste of water resources. Example 2
[0043] Based on Example 1, in this example: the water tank 4 is equipped with a crushing mechanism for pre-treating solid purifying agent particles.
[0044] The crushing mechanism includes a crushing box 20 fixedly installed on the top of the water tank 4, two crushing rollers 21 rotatably connected inside the crushing box 20 and extending out of the crushing box 20 at one end, gears 22 fixedly installed at one end of the two crushing rollers 21 and meshing with each other, a second motor 23 fixedly installed on one side of the crushing box 20, and a stirring component provided inside the water tank 4. The output end of the second motor 23 is connected to the end face of a gear 22. Inside the crushing box 20, there are two guide plates that guide the flow to the middle.
[0045] The stirring component includes a stirring shaft 24 rotatably connected between the two sides of the inner wall of the water tank 4, and a pulley assembly 25 disposed between the stirring shaft 24 and the crushing roller 21. One end of the stirring shaft 24 extends movably out of the water tank 4, and the pulley assembly 25 is respectively installed on one end of the stirring shaft 24 and the end face of another gear 22.
[0046] The technical solution provided in this embodiment is as follows: When adding purifying agent particles, the purifying agent is added into the crushing box 20, and the two crushing rollers 21 are rotated relative to each other by the motor 23 and two gears 22 to crush the purifying agent particles, so as to improve the water dissolution efficiency. The crushed purifying agent enters the water tank 4. At the same time, when the crushing rollers 21 rotate, under the action of the pulley assembly 25, they can drive the stirring shaft 24 to rotate, so that the stirring shaft 24 stirs the water in the water tank 4, thereby accelerating the mixing speed and uniformity of the purifying agent, which is conducive to ensuring the effect of subsequent exhaust gas purification.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
