The return pipe 111 is fixedly mounted on the side of the water tank 101, a pump 113 is arranged in the middle of the return pipe 111, a spiral pipe 115 is connected to the top of the return pipe 111, the spiral pipe 115 surrounds the outer surface of the air receiving pipe 104, and the end of the spiral pipe 115 passes through the top wall of the water tank 101 and is connected to a water distributor 116, a partition is arranged between the water distributor 116 and the clean air pipe 117, the outer end of the clean air pipe 117 is connected to a guide valve pipe 118, and the end of the guide valve pipe 118 is connected to a distributor. The air plate 119 is provided, and an activated carbon adsorption box 120 is sleeved on the guide valve tube 118. There are two activated carbon adsorption boxes 120, which are respectively connected to the two air outlet ends of the guide valve tube 118. An adsorbed activated carbon 121 is inserted into the activated carbon adsorption box 120. The outer end of the adsorbed activated carbon 121 is connected to an exhaust head 122. An activated carbon rod 123 is inserted in the middle of the exhaust head 122. The end of the activated carbon rod 123 is located deep in the groove of the adsorbed activated carbon 121.

[0022] Specifically, the condensation rod 110 is set at the bend of the heat exchange tube 108 to cool the water source inside the heat exchange tube 108, thereby ensuring the temperature circulation of the water source and avoiding absorbing too much heat to cause the temperature to rise, affecting the temperature of the gas discharged from the clean air pipe 117, thereby damaging the adsorbed activated carbon 121 and reducing its lifespan, thereby improving the practicality of the device. In addition, the spiral tube 115 is wrapped around the air connecting pipe 104 to perform a preliminary cooling of the industrial waste gas and improve the cooling efficiency.

[0023] Embodiment 2:

[0024] Combination Figure 1-2 As shown, based on the first embodiment, the bottom of the water pumping pipe 106 is connected to a sewage pipe 107 , the bottom end of the return pipe 111 is connected to a new water pipe 112 , and valves are provided on the sewage pipe 107 and the new water pipe 112 .

[0025] Specifically, the dirty water inside the water tank 101 can be discharged by using the sewage pipe 107, so that the water source inside the water tank 101 can maintain the characteristic of adsorbing toxic substances, avoiding the dissolution of toxic substances in the water source to reach saturation, and at the same time, new water source can be injected by using the new water pipe 112 to maintain the activity of the water source, so that the adsorbed activated carbon 121 can work for a longer time, reducing the number of activated carbon regeneration steps, thereby reducing costs, and the activated carbon can be replaced once a longer period of time, further reducing costs.

[0026] The working principle and use process of the utility model are as follows: first, the device is installed, and the power supply is connected to start the device at the same time, and the air connection pipe 104 is connected to the discharge port of the chemical waste gas. The waste gas is discharged into the water source inside the water tank 101 through the air distribution pipe 105, and the water source is used to adsorb particulate matter and toxic substances dissolved in water. The purified waste gas enters the guide valve pipe 118 through the clean air pipe 117, and enters one of the air distribution plates 119 according to the guidance of the guide valve pipe 118, and is evenly discharged into the activated carbon adsorption box 120 through the air distribution plate 119. The toxic substances in the chemical waste gas are adsorbed by the adsorption activated carbon 121, and then discharged to the next step or the outside through the exhaust head 122;

[0027] The bottom of the water tank 101 is connected with a water pump 106, which guides the water source inside the water tank 101 to the heat exchange tube 108, cools it by using a condenser rod 110, extracts it through a pump 113, circulates it to the spiral tube 115, and performs a preliminary cooling on the chemical waste gas inside the air pipe 104 before discharging it into the water tank 101 again;

[0028] In addition, after the water source inside the water tank 101 has absorbed toxic substances and particulate matter, the valves on the sewage pipe 107 and the new water pipe 112 are opened to change the water. Similarly, when the activated carbon rod 123 is fully adsorbed, the route is switched through the guide valve pipe 118, and another activated carbon adsorption box 120 can be used for activated carbon adsorption, and new adsorption activated carbon 121 can be replaced at the same time;

[0029] Finally, it is sufficient to inspect and maintain the device regularly.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
