Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas spray tower device for waste gas treatment. Background Art

[0002] Waste gas refers to the toxic and harmful gases discharged during the production and living processes, especially the generation of waste gas from chemical plants, steel plants, pharmaceutical factories, coking plants, oil refineries, etc. and domestic waste gas brought by life. The discharged waste gas has a strong smell, seriously pollutes the environment and affects human health.

[0003] When the existing spray tower for waste gas treatment is in use, the position of the spray head is fixed, so that the spray solution cannot be evenly sprayed, and the spray solution cannot be evenly distributed in the spray tower to fully mix with the waste gas, which is inconvenient to use and reduces the treatment effect on the waste gas. Therefore, there is an urgent need for a technology that can improve the structure of the spray tower for waste gas treatment to improve this device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background art, and to provide a waste gas spray tower device for waste gas treatment.

A waste gas pipe and a liquid discharge pipe are fixedly penetrated through the side wall of the tower body, and an exhaust pipe is fixedly communicated with the top of the tower body. A filter plate is arranged below the waste gas pipe and installed inside the tower body;

[0007] The swing type spray component includes a spray cylinder rotatably installed inside the tower body, and the spray cylinder is located above the filter plate. A plurality of spray heads are fixedly communicated with the bottom of the spray cylinder. A liquid inlet pipe communicated with the spray cylinder penetrates through the top of the tower body. A swing frame coaxially connected with the spray cylinder is rotatably installed on the surface of the tower body.

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1 to 4, An exhaust gas spray tower device for exhaust gas treatment, including a tower body 1 and a swing-type spray assembly. The side wall of the tower body 1 is fixedly penetrated with an exhaust gas pipe 2 and a drain pipe 4. Valves (not shown in the figure) are also installed on the drain pipe 4, and the top of the tower body 1 is fixedly communicated with an exhaust pipe 5. During the exhaust gas spray treatment process, the two valves are closed, so as to ensure that the exhaust gas after spray treatment can only be discharged from the exhaust pipe 5. Below the exhaust gas pipe 2, there is a filter plate 3 installed in the tower body 1. During spray dust removal, particulate matter will be intercepted on the surface of the filter plate 3, and the aqueous solution will be discharged from here after the treatment is over by opening the valves on the two drain pipes 4.

[0022] The swing-type spray assembly includes a spray cylinder 6 rotatably installed in the tower body 1, and the spray cylinder 6 is located above the filter plate 3. The bottom of the spray cylinder 6 is fixedly communicated with a plurality of spray heads 7. The top of the tower body 1 is penetrated with a liquid inlet pipe 8 communicated with the spray cylinder 6. The liquid inlet pipe 8 is a flexible pipe. The surface of the tower body 1 is rotatably installed with a swing frame 9 coaxially connected with the spray cylinder 6. A sliding hole 10 is opened on the surface of the swing frame 9, and a crankshaft 11 is slidably connected in the sliding hole 10. The diameter of the crankshaft 11 is equal to the width of the sliding hole 10, ensuring the stability of the crankshaft 11 sliding in the sliding hole 10.

[0023] Two right-angle frames 16 are symmetrically and fixedly installed on the surface of the tower body 1. A motor 12 for driving the crankshaft 11 is fixedly installed between the two right-angle frames 16. During use, an external pump is used to pump the solution for treating exhaust gas into the liquid inlet pipe 8 (the solution here is an alkaline solution, an acidic solution, an oxidizing solution or an adsorbent solution, which can be used according to actual needs). At the same time, the motor 12 is started to drive the end of the crankshaft 11 away from it to perform circular motion, sliding up and down, from bottom to top in the sliding hole 10, which can push the swing frame 9 to drive the spray cylinder 6 and each spray head 7 to swing reciprocally, increasing the coverage range of the spray solution. At this time, the external pump is used to pump the exhaust gas into the tower body 1 through the exhaust gas pipe 2, so that the spray solution can be evenly distributed in the tower body 1 and fully mixed with the exhaust gas, thereby improving the treatment effect on the exhaust gas.

[0024] Furthermore, a collection box 13 is slidably inserted into the front side of the tower body 1. A handle 15 is fixedly installed on the front wall of the collection box 13. A through hole 14 is opened at the bottom of the collection box 13. The filter plate 3 is slidably placed in the collection box 13. The size of the filter plate 3 is larger than the size of the through hole 14. After the spray treatment is over, the collection box 13 can be pulled out through the handle 15, and then the filter plate 3 can be pushed out upward from the through hole 14 for cleaning and maintenance.
