Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, a waste gas guiding structure includes a guide pipe 100. The top end of the guide pipe 100 has an outlet 120, and the side wall at the bottom end of the guide pipe 100 has an inlet 110. A connecting section 111 is provided between the inlet 110 and the wall of the guide pipe 100. The end of the connecting section 111 connected to the inlet 110 is inclined upwards. Ventilation devices 130 are provided in both the inlet 110 and the outlet 120. The ventilation devices 130 are used to draw waste gas from the inlet 110 into the guide pipe 100 and discharge it from the outlet 120. In practical applications, the ventilation devices 130 can be common devices such as exhaust fans and blowers. Because this embodiment treats waste gas by contacting it with liquid, the connecting section 111 can prevent interference between subsequent waste gas treatment and intake operations, and prevent liquid from entering the inlet 110 and damaging the equipment.

[0022] like Figure 1 , 2 As shown, a plurality of first filter plates 140 and second filter plates 150 are provided between the air inlet 110 and the air outlet 120. The first filter plates 140 and second filter plates 150 are important components for bringing exhaust gas into contact with liquid. Each first filter plate 140 and second filter plate 150 is spaced apart. The first filter plate 140 includes two first filter sections 142 connected in an inverted V-shape. A first overflow groove 141 is provided between the two first filter sections 142. The first overflow groove 141 is a U-shaped groove that overflows from both sides simultaneously. The two ends of the first overflow groove 141 are respectively connected to the upper ends of the two first filter sections 142. The liquid overflowing from both sides of the first overflow groove 141 flows to the surface of the two first filter sections 142. When exhaust gas passes through the first filter sections 142, the exhaust gas comes into contact with the liquid on the first filter sections 142, thereby achieving exhaust gas filtration. The second filter plate 150 includes two second filter sections 152 connected in a V-shape. Each of the two second filter sections 152 has a second overflow groove 151 at one end, away from each other. One side of the second overflow groove 151 is fixed to the inner wall of the guide pipe 100, and the other side is the overflow side, which is connected to the upper end of the second filter section 152. The liquid overflowing from the overflow side of the second overflow groove 151 flows onto the surface of the second filter section 152. When exhaust gas passes through the second filter section 152, the exhaust gas comes into contact with the liquid on the second filter section 152, thus achieving exhaust gas filtration.

[0023] like Figure 2As shown, in the embodiment, the first filter plates 140 and the second filter plates 150 are arranged in sequence and spaced apart from each other. The liquid on the first filter plate 140 flows down from the end of the first filter section 142 after flowing over the surface of the first filter section 142. The second overflow groove 151 corresponds to the end of the first filter section 142, and the liquid flowing down from the end of the first filter section 142 enters the second overflow groove 151 of the second filter plate 150 below. When the second overflow groove 151 is full, the liquid overflows to the surface of the second filter section 152. The connection between the two second filter sections 152 is provided with a drain, which corresponds to the first overflow groove 141. The water flowing through the second filter section 152 flows down from the drain to the first overflow groove 141 of the first filter plate 140 below. By arranging the first filter plates 140 and the second filter plates 150 in sequence and spaced apart from each other, the water flow can completely flow through each layer of the first filter plates 140 and the second filter plates 150, so that the liquid can be fully contacted with the exhaust gas.

[0024] As shown in Figure 2 , 3 , the first filter section and the second filter section are each provided with a plurality of wave-shaped protrusions 160. Adjacent two wave-shaped protrusions 160 form a wave-shaped groove 161, and the groove bottom of the wave-shaped groove 161 is provided with a plurality of openings 162. The exhaust gas entering the flow guide pipe 100 from the air inlet 110 will be discharged from the air outlet 120 after passing through the openings 162 and the wave-shaped grooves. In this process, the exhaust gas will be contacted with the liquid. The wet wave-shaped groove 161 can increase the contact area of the gas and the liquid, and improve the filtering effect. The first overflow groove 141 and the second overflow groove 151 supply water to the first filter section 142 and the second filter section 152, respectively, by overflow. The overflowed water will uniformly enter the first filter section 142 and the second filter section 152, and flow in the wave-shaped grooves 161. The wave-shaped grooves 161 can prevent the liquid from deviating to other wave-shaped grooves 161 or gathering during the flow process, avoid the problem that the water flow cannot completely cover the entire plate surface and cannot form a water curtain, and effectively ensure that the liquid on the first filter section 142 and the second filter section 152 is completely covered.

[0025] As shown in Figure 2 , 3As shown, the groove width of the wave-shaped groove 161 is 5mm, and the diameter of the opening 162 is smaller than the groove width of the wave-shaped groove 161, and based on the influence of liquid surface tension, the smaller aperture can prevent liquid from flowing down from the opening 162 in large quantities. When the water flows through the first filter section 142 and the second filter section 152, part of the water flow will fall from the opening 162. The density of the opening gradually decreases from top to bottom along the wave-shaped groove, which can avoid excessive reduction of water flow when the liquid flows to the end of the first filter section 142 and the second filter section 152, and balance the water flow of the entire plate surface. The flow guide pipe 100 is provided with a water supply pipe 170 for supplying water to the first overflow groove 141, water is supplied to the uppermost first overflow groove 141, and the water flow can completely flow through the surface of each first filter plate 140 and second filter plate 150 below by relying on the cooperation and arrangement of the first filter plate 140 and the second filter plate 150, so that the waste gas and the liquid are fully contacted. The bottom end of the flow guide pipe 100 is provided with a waste liquid tank 190, and the liquid after treating the waste gas finally flows into the waste liquid tank 190 for collection and treatment. One side of the flow guide pipe 100 is also provided with a liquid supply container 180, and the liquid supply container 180 is provided with a water pump 181, and the water pump 181 is connected with the water supply pipe 170. The liquid supply container 180 is used for storing the liquid for treating waste gas, and different liquids can be added according to actual needs during use, so as to treat different waste gas.

[0026] The above embodiments are the preferred implementation of the present application, and are not a limitation of the present application. Any obvious replacement without departing from the inventive concept of the present application is within the protection scope of the present application.
