[0004] The above patent can increase the uniformity of the exhaust gas flow into the tower body and prolong the contact time with the absorption liquid. When the exhaust gas is purified in industry, the exhaust gas emission is large, and the gas cannot be fully up to standard through a one-time filtering spray. The above patent can only extend the spraying time, but when the gas flow rate is fast, the short extension cannot completely filter the gas. Moreover, the factory produces more than one product, and the exhaust gas that needs to be filtered may also be different. Therefore, some gases need to be filtered multiple times to meet the preset standards.

[0005] In order to solve the above problems, the utility model proposes a waste gas spray tower device for waste gas treatment. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-Figure 5 As shown, the utility model is a waste gas spray tower device for waste gas treatment, comprising a spray tower body 1, a plurality of air inlets 11 are arranged on one side of the spray tower body 1, a liquid supply assembly is arranged at the outer bottom of the spray tower body 1, a liquid inlet pipe 33 for liquid transmission is arranged inside the spray tower body 1, both sides of the liquid inlet pipe 33 are coupled and connected with a cross pipe 34, and a spray member 35 is arranged below the cross pipe 34;

[0026] The spray member 35 includes a spray pipe 351 , which is connected to the horizontal pipe 34 . A spray head 352 is fixedly threadedly connected to the lower surface of the spray pipe 351 , and a spiral spray port 353 is formed on the side wall of the spray head 352 .

[0027] The air inlet 11 is arranged at different heights on the side wall of the spray tower body 1. It can be connected to external waste equipment to work simultaneously, or one air inlet 11 can be opened separately to input waste gas. A spray part 35 is arranged above each air inlet 11 to ensure that the gas entering from any air inlet 11 can achieve the effect of spraying and purifying the waste.

[0028] When waste is introduced from the lower air inlet 11, since the lowermost air inlet 11 is farther from the top air outlet (refer to Figure 1 As shown in the figure, the distance is the largest, so the time is the longest, and the multi-layer spraying parts 35 spray the exhaust gas, thereby achieving a better effect on the waste treatment.

[0029] The high-pressure liquid for spraying is transmitted to the transverse pipes 34 arranged on both sides through the liquid inlet pipe 33. The arrangement of the transverse pipes 34 can increase the range of spraying. The transverse pipes 34 transmit the high-pressure spraying liquid to the spray head 352 through the spray pipe 351 arranged at the bottom, and spray it out from the spiral spray port 353. The spiral spray port 353 is arranged in a spiral. The high-pressure spraying liquid hits the spiral spray port 353 and opens to the surroundings, thereby making the spraying effect better.

[0030] Specifically, the liquid supply assembly includes a liquid storage tank 2 , which is connected to the bottom of the spray tower body 1 . A high-pressure pump 3 is connected to one side of the liquid storage tank 2 , and a water inlet end of the high-pressure pump 3 is connected to the liquid storage tank 2 .

[0031] The high-pressure pump 3 can continuously pump out the spray liquid from the liquid storage tank 2 to provide power for the flow of the spray liquid. The liquid at the bottom of the spray tower body 1 will flow into the liquid storage tank 2 for recycling.

[0032] Specifically, the water outlet end of the high-pressure pump 3 is fixedly connected to a water supply pipe 31 , a connecting flange 32 is provided through the side wall of the water supply pipe 31 , and the liquid inlet pipe 33 is connected to the water supply pipe 31 via the connecting flange 32 .

[0033] The high-pressure spraying liquid enters the liquid inlet pipe 33 through the water supply pipe 31. The arrangement of the connecting flange 32 facilitates the installation of the liquid inlet pipe 33 and increases the stability of the liquid inlet pipe 33 during operation.

[0034] Specifically, an inner bracket is fixedly connected to the inner wall of the spray tower body 1, and filters 41, 42, 43 are installed on the upper surface of the inner bracket.

[0035] The spray tower body 1 can wash away dirt attached to the surfaces of the filter screens 41, 42, and 43 during use. When the exhaust gas passes through the filter screen, the filter screen can filter the exhaust gas. The filter screen being in a wet state can achieve a better filtering effect.

[0036] Specifically, a water purification filter disc 5 is fixedly mounted on the upper surface of a bracket 13 disposed at the bottom layer of the spray tower body 1 .

[0037] The sprayed liquid will be filtered again through the water purification filter disc 5, and the water purification filter disc 5 can bring impurities in the exhaust gas to the surface of the water purification filter disc 5. After passing through the surface of the water purification filter disc 5, the sprayed liquid enters the bottom of the spray tower body 1 for reuse.

[0038] Specifically, a liquid indicator 21 is disposed on one side of the liquid storage tank 2 , and the liquid indicator 21 is disposed in communication with the liquid storage tank 2 .

[0039] The liquid level inside the liquid storage tank 2 can be displayed in real time by the liquid indicator 21. During the spraying process, a large amount of spraying liquid will be lost. When the liquid indicator 21 reaches the preset liquid level, new spraying liquid needs to be added to the liquid storage tank 2 in time.

[0040] Working principle: During the working process, firstly, the exhaust pipe is connected to the corresponding air inlet 11 according to the exhaust gas discharged, the corresponding spray liquid is added to the liquid storage tank 2, and the high-pressure pump 3 is turned on. During the working process, the high-pressure pump 3 pumps the spray liquid from the liquid storage tank 2 into the water supply pipe 31, and then enters the liquid inlet pipes 33 at different heights after entering the water supply pipe 31, and enters the spray part 35 arranged below through the horizontal pipes 34 arranged on both sides, and is sprayed out through the spray part 35 to achieve the purpose of purifying the exhaust gas.

[0041] After the spray liquid enters the spray head 352 through the spray pipe 351, it is sprayed out through the spiral spray port 353. The spiral spray port 353 can disperse the spray liquid to achieve a wider spray range, which is conducive to more thorough purification of the exhaust gas.

[0042] The exhaust gas can be filtered through the filter screens 41, 42, 43, and the filter screens 41, 42, 43 are in a wet state during spraying, so that the filter screens 41, 42, 43 have a better effect in filtering the exhaust gas.

[0043] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
