After the filtering mechanism is used for a long time, the filter mesh holes will be blocked, affecting the filtering effect and the flow of gas. Therefore, it is necessary to regularly prevent blockage and clean it. However, since the filter is installed inside the tower body, it takes a long time to clean it, and the operation is more troublesome. Of course, there are also cases where a cleaning structure is installed on the filter, but the filter is not moved out of the tower body for cleaning. Impurities on the filter will fall to the bottom of the tower body, affecting the use of the water scrubber. Utility Model Content

[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please refer to Figure 1-Figure 7 The utility model embodiment provides an anti-clogging structure of a water washing tower, including a tower body 1, wherein a feed pipe 11 and a discharge pipe 12 are respectively arranged on the upper and lower sides of the tower body 1, the discharge port of the feed pipe 11 is connected to an extension pipe 17 inside the tower body 1, and a filter box 2 is arranged at the discharge port of the extension pipe 17. After the gaseous hydrocarbon mixture enters the tower body 1 through the feed pipe 11, it is transported to the filter box 2 through the extension pipe 17 for filtration, and the impurities in the gas are filtered out through a filter screen 23 movably arranged in the filter box 2, and the filtered gas flows to the bottom of the tower body 1.

[0030] Since a diffusion cover 21 is arranged at the lower side of the filter box 2, the diffusion cover 21 diffuses the gas so that the gas enters the bottom of the tower evenly. At the same time, a distributor 15 is arranged in the tower body 1 located at the lower side of the diffusion cover 21. The distributor 15 makes the gas fully contact with the filler 14. At the same time, a spray pipe 16 is arranged at the lower side of the distributor 15, and the spray pipe 16 supplies water through the water pump 13. The gas and water contact on the surface of the filler 14 and perform a mass transfer process. Due to the low solubility of olefins, they are gradually separated from the hydrocarbon mixture and flow to the bottom of the tower with water. At the bottom of the tower, the olefins and water form two phases, and then the olefins are separated from the water by the separation equipment.

[0031] In order to prevent the filter screen 23 from being blocked, a processing box 3 is provided on one side of the filter box 2 , a perforation is provided on the wall surface where the filter box 2 and the processing box 3 are connected, and an anti-blocking mechanism is installed in the processing box 3 .

[0032] Among them, installation grooves 22 are opened on the inner walls of both sides of the filter box 2, and screw rods 24 are rotatably arranged in the two installation grooves 22. The two screw rods 24 are connected by a transmission member 25. The sliders on both sides of the filter screen 23 slide in the two installation grooves 22 respectively and are threadedly connected with the screw rods 24. The transmission member 25 is driven by a motor. When the screw rods 24 rotate, the filter screen 23 passes through the perforation and moves into the treatment box 3 to prevent blocking.

[0033] Specifically, the anti-blocking mechanism includes a limit plate 33 arranged on the inner walls on both sides of the processing box 3, a slide rail 34 is arranged on the upper side of the limit plate 33, a slideway is formed between the slide rail 34 and the limit plate 33, the filter 23 is slidably connected to the slideway, and a brush 36 is slidably arranged in the slide rail 34. When the filter 23 enters the processing box 3, the bristles of the brush 36 fit with the upper surface of the filter 23. The filter 23 can be prevented from being blocked by the movement of the brush 36.

[0034] Furthermore, a screw rod 2 35 is rotatably disposed in one of the slide rails 1 34 , and the screw rod 2 35 is threadedly connected to one end of the brush 36 . The screw rod 2 35 is driven by a motor, so when the screw rod 2 35 rotates, the brush 36 automatically cleans the debris.

[0035] In addition, slide rails 24 are symmetrically arranged at the upper end of the processing box 3, and connecting plates 43 are slidably arranged in the symmetrical slide rails 24. A cleaning pipe 44 is arranged between the two connecting plates 43. The water inlet pipe of the cleaning pipe 44 passes through the opening 31 opened at the end of the processing box 3 and extends to the outside. After the water inlet pipe is connected to the external water source, clean water can be provided to the cleaning pipe 44, and the filter screen 23 is sprayed through the cleaning pipe 44 to enhance the anti-blocking effect.

[0036] The cleaning pipe 44 is located in front of the brush 36, so the cleaning pipe 44 sprays the filter 23 first, which helps to improve the brushing effect of the brush 36. At the same time, push rods 37 are provided on both sides of the brush 36, and an extension plate 38 is provided on one side of the push rod 37. The position of the push rod 37 corresponds to the position of the connecting plate 43, and the extension plate 38 is located on one side of the connecting plate 43. Therefore, when the brush 36 moves, the connecting plate 43 is pushed to move by the push rod 37 and the extension plate 38, so that the cleaning pipe 44 can achieve mobile spraying.

[0037] Therefore, slide grooves 41 are provided on both sides of the slide rail 4 , and the protrusions provided on both sides of the connecting plate 43 are respectively slidably connected to the two slide grooves 41 , thereby improving the stability of the cleaning pipe 44 .

[0038] Furthermore, a spring 42 is provided in the slide rail 2 4, one end of the spring 42 is connected to the connecting plate 43, and when the cleaning tube 44 moves, the connecting plate 43 squeezes the spring 42, and when the push rod 37 moves back, the spring 42 loses its force, causing the cleaning tube 44 to slowly return to its original position.

[0039] Since the lower side of the treatment box 3 is a conical structure, it is convenient to collect the cleaned sewage, and a conduit 32 is provided on the lower side of the treatment box 3, and the conduit 32 extends to the outside of the tower body 1, so as to discharge the sewage.

[0040] In summary, the anti-clogging structure of a water washing tower in an embodiment of the utility model has the following working principle: the filter screen 23 is moved into the processing box 3 by rotating the screw 24, and the filter screen 23 is cleaned by using the brush 36, and at the same time, the filter screen 23 is sprayed with the cleaning pipe 44 to prevent the mesh from being blocked. When the brush 36 moves, the push rod 37 and the extension plate 38 push the connecting plate 43, so that the cleaning pipe 44 moves with the brush 36, and the cleaning pipe 44 is located in front of the brush 36, so that the brush 36 brushes the filter screen 23 after spraying, which helps to improve the cleaning effect.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
