Description

Technical Field

[0001] The present application relates to the technical field of industrial waste gas treatment equipment, and specifically to a spraying method treatment equipment for industrial waste gas. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] Pollutants in industrial waste gas, such as dust, harmful gases and fine particles, can be treated by spraying. The spraying method is to spray liquid into contact with industrial waste gas, which can effectively absorb or chemically react to remove pollutants in the waste gas. For example, alkaline solution can neutralize acidic gases, while oxidants can destroy organic pollutants.

[0004] Patent Publication (Announcement) No.: CN104707446A, discloses a spray treatment equipment for industrial waste gas, which can greatly improve the uniformity of spraying by precisely controlling each nozzle, including a spiral nozzle and a cleaning nozzle, through an electromagnetic valve. The absorption liquid spray device and the cleaning liquid spray device are both provided with radial spray pipes, and the rotating nozzle is arranged at the center of the spray tower by using the radial spray pipes. In this way, the absorption liquid can be sprayed into the spray tower with the rotating nozzle as the center, so that the waste gas in the spray tower is fully contacted with the absorption liquid. However, the rotating nozzle is at the center of the spray tower, and the spray range of some rotating nozzles is limited. Some positions close to the side wall of the spray tower cannot be covered, so there will be some spray loopholes, causing the escape of industrial waste gas and unable to fully contact with the industrial waste gas. Therefore, a spray treatment equipment that can completely absorb the industrial waste gas is needed. Utility Model Content

[0023] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0024] A spraying treatment device for industrial waste gas, such as Figure 1-Figure 3 As shown, it includes: a spray tower 1, which is a rectangular spray tower 1, and a plurality of air inlets 6 are arranged on the side wall of the spray tower 1, and a spray net 9 is arranged above each air inlet 6, and the spray net 9 is composed of three horizontal tubes 11 and three vertical tubes 12 to form a rectangular grid-shaped spray net 9, and the horizontal tubes 11 and the vertical tubes 12 are perpendicular to each other, and each horizontal tube 11 and each vertical tube 12 are respectively provided with five nozzles 10, and the spray net 9 is fixedly connected to the side wall of the spray tower 1, and a nozzle 10 is arranged at one end of the spray net 9 close to the side wall to prevent the spray net 9 from being unable to spray into the space near the side wall.

[0025] like Figure 1 As shown, it also includes: a collecting box 2, a liquid storage tank 3, and a liquid extraction pump 4. An opening is provided at the bottom of the spray tower 1, and the opening is connected to the collecting box 2. A liquid storage tank 3 is provided on one side of the spray tower 1. The liquid storage tank 3 is filled with absorption liquid, and the absorption liquid absorbs the industrial waste gas. A liquid extraction pump 4 is provided on the liquid storage tank 3. The liquid extraction pump 4 is connected to the spray net 9 through a pipeline. The liquid extraction pump 4 transports the absorption liquid in the liquid storage tank 3 to the spray net 9.

[0026] like Figure 2 As shown, a rotating nozzle 10 is provided on the side of the spray net 9 facing the collection box 2 , twenty-one rotating nozzles 10 are evenly distributed on the spray net 9 , and the intersection of the horizontal pipe 11 and the vertical pipe 12 shares one rotating nozzle 10 .

[0027] like Figure 2 As shown, the spray net 9 has two layers, and the two layers of spray nets 9 are parallel to each other. Two air inlets 6 are respectively arranged under the two layers of spray nets 9, so that the industrial waste gas can enter the spray tower 1 faster through the two air inlets 6, thereby improving the treatment efficiency of the industrial waste gas.

[0028] like Figure 2As shown, a demister 5 is also provided on the top of the spray tower 1 to prevent the sprayed absorption liquid from escaping from the spray tower 1.

[0029] like Figure 1 As shown, a drain port 7 is provided at the bottom of the collecting box 2 , and the absorption liquid mixed with the exhaust gas flows into the collecting box 2 and is discharged through the drain port 7 .

[0030] A booster pump is also provided between the liquid extraction pump 4 and the spray net 9, and the booster pump is used to increase the injection pressure of the absorption liquid in the spray net 9, so that the absorption liquid sprayed in the nozzle 10 has a wider range.

[0031] like Figure 1 As shown, the liquid storage tank 3 is also provided with a liquid inlet 8 to facilitate the replenishment of the absorption liquid.

[0032] like Figure 2 As shown, the spray net 9 is perpendicular to the side wall of the spray tower 1, and the nozzle 10 faces the collecting box 2, so that the absorption liquid sprayed by the nozzle 10 is on the cross section perpendicular to the spray tower 1, and the spraying range is maximized to prevent the escape of excess industrial waste gas. The air inlet 6 is perpendicular to the side wall of the spray tower 1, so that the nozzle 10 on the spray net 9 can be directly aimed at the industrial waste gas at the air inlet 6, so that the absorption liquid sprayed by the nozzle 10 can absorb all the industrial waste gas.

[0033] like Figure 3 As shown, the distances between adjacent transverse tubes 11 are equal, and the distances between adjacent longitudinal tubes 12 are equal, so that the nozzles 10 on the transverse tubes 11 and the longitudinal tubes 12 can spray the absorption liquid more evenly.

[0034] In the technical solution of the present application, industrial waste gas is input into the spray tower 1 through multiple air inlets 6 to speed up the speed of industrial waste gas entering the spray tank and improve the treatment efficiency of industrial waste gas. Then, the liquid pump 4 is turned on to transport the absorption liquid in the liquid storage tank 3 to the spray net 9. The absorption liquid is sprayed on the cross section perpendicular to the spray tower 1 through the rectangular grid-shaped spray net 9. In this way, the rectangular cross section of the spray tower 1 can be fully covered to fully contact the absorption liquid with the industrial waste gas, thereby avoiding overflow or leakage of industrial waste gas. In addition, a nozzle 10 is provided on the rectangular grid-shaped spray pipe near the side wall of the spray tower 1 to prevent the industrial waste gas near the side wall from contacting the absorption liquid.

[0035] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
