Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, and more specifically, it relates to a waste gas treatment device. Background Technique

[0002] A waste gas treatment device refers to a device used to treat polluted gases generated in production activities. Different waste gases have different treatment methods. One of the common waste gas treatment methods is to use the liquid spraying downwards to absorb harmful substances in the waste gas, and then discharge the waste gas after harmless treatment. However, the liquid in the existing spray-type waste gas treatment device naturally spills, and the contact with the waste gas is not sufficient.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a waste gas treatment device.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A waste gas treatment device includes a housing. A water inlet pipe and an air inlet pipe are fixedly connected to the side wall of the housing. An air outlet cap is provided at one end of the air inlet pipe located inside the housing. The air outlet cap is coaxially arranged with the housing. A plurality of plates are provided on the side wall of the air outlet cap. The diameters of the plurality of plates gradually increase along the vertically downward direction. A plurality of air holes are provided on the side wall of the air outlet cap. The air holes are located between the plates. The water inlet pipe located inside the housing faces the uppermost plate from top to bottom.

[0006] The utility model is further provided that: the thickness of the plate gradually decreases along the direction away from the axis of the air outlet cap.

[0007] The utility model is further provided that: the number of the plates is greater than or equal to three.

[0008] The utility model is further provided that: the bottom of the air outlet cap is threadedly connected to the air inlet pipe.

[0009] The utility model is further provided that: a through groove is provided through the edge of the lowermost plate.

[0010] The utility model is further provided that: the housing includes a top cover and a bottom pipe that are detachably connected to each other. The top cover is fixedly connected to the water inlet pipe. The bottom pipe is fixedly connected to the air inlet pipe.

[0011] In summary, the utility model has the following beneficial effects: Water flow falls from the water inlet pipe onto the uppermost plate. The water flow falling along the edge of the plate forms a water curtain. The waste gas in the air outlet cap gushes out along the air holes and contacts the water curtain, ensuring sufficient contact between the waste gas and the water flow, improving the effect of waste gas treatment. Through the cooperation of multiple groups of air holes and multiple water curtains, the efficiency of waste gas treatment is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following combines the drawings and embodiments to describe the utility model in detail.

[0015] Embodiment: An exhaust gas treatment device, as Figure 1 shown, includes a housing. A water inlet pipe 1 and an air inlet pipe 2 are fixedly connected to the side wall of the housing. One end of the air inlet pipe 2 located inside the housing is provided with an air outlet cap 3. The air outlet cap 3 is coaxially arranged with the housing. A plurality of plates 4 are provided on the side wall of the air outlet cap 3. The diameters of the plurality of plates 4 gradually increase along the vertically downward direction. A plurality of air holes 5 are formed in the side wall of the air outlet cap 3. The air holes 5 are located between the plates 4. One end of the water inlet pipe 1 located inside the housing faces the uppermost plate 4 from top to bottom.

[0016] Specifically, both the water inlet pipe 1 and the air inlet pipe 2 are in an L shape. The air inlet pipe 2 is located above the water inlet pipe 1. The air outlet cap 3 is located between the air inlet pipe 2 and the water inlet pipe 1. The waste gas flows from the air inlet pipe 2 into the air outlet cap 3. The water flow falls from the water inlet pipe 1 onto the uppermost plate 4. The water flow falling along the edge of the plate 4 forms a water curtain. The waste gas in the air outlet cap 3 gushes out along the air holes 5 and contacts the water curtain, ensuring sufficient contact between the waste gas and the water flow and improving the effect of waste gas treatment.

[0017] The thickness of the plate 4 gradually decreases along the direction away from the axis of the air outlet cap 3. The number of plates 4 is greater than or equal to three. Specifically, the top surface of the plate 4 is inclined to ensure that the water flow moves in the direction away from the axis of the air outlet cap 3, preventing the water flow from entering the air outlet pipe along the air holes 5. In this embodiment, the number of plates 4 is three. There are two groups of air holes 5 between the three plates 4. Through the cooperation of multiple groups of air holes 5 and multiple water curtains, the efficiency of waste gas treatment is improved.

[0018] The bottom of the air outlet cap 3 is threadedly connected to the intake pipe 2. A through groove 6 is provided through the edge of the lowermost plate 4. The housing includes a top cover 7 and a bottom pipe 8 that are detachably connected to each other. The top cover 7 is fixedly connected to the water inlet pipe 1, and the bottom pipe 8 is fixedly connected to the intake pipe 2. Specifically, an exhaust port is provided on the top surface of the top cover 7, and a drain port is provided on the bottom surface of the bottom pipe 8. The top cover 7 and the bottom pipe 8 are connected by a sleeve. The plate 4 and the air outlet cap 3 are integrally formed. The threaded connection makes the air outlet cap 3 detachable from the intake pipe 2, which is easy to maintain and replace. When the air outlet cap 3 needs to be disassembled, separate the top cover 7 and the bottom pipe 8, and take out the air outlet cap 3 from above. This embodiment is applicable to small-scale waste gas treatment. Therefore, the inside of the bottom pipe 8 is relatively narrow. The through groove 6 provided on the lowermost plate 4 facilitates the rotation of the air outlet cap 3. When the air outlet cap 3 needs to be rotated, insert a rod-shaped tool into the through groove 6 to start rotating the air outlet cap 3. After the air outlet cap 3 is loosened from the intake pipe 2, the air outlet cap 3 can be unscrewed by hand.

[0019] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as within the protection scope of the present invention.
