An exhaust fan 102 is clamped through the outer circumference of the exhaust pipe 101. A reaction pipe 2 is set at the bottom of the cooling connecting pipe 1. A liquid pump 202 is clamped and fixed at the top of one end of the reaction pipe 2. A spray pipe 212 is clamped through one end of the liquid pump 202. A condenser pipe 201 is welded through the top of the outer circumference of the reaction pipe 2. An air quality monitoring component 206 is clamped through the outer circumference of the condenser pipe 201. The mounting bracket 3 is sleeved on the outer circumference of both the cooling connecting pipe 1 and the reaction pipe 2.

One reaction tube 2 at the end is connected to the cooling connection pipe 1. The reaction tube 2 and the cooling connection pipe 1 are then fixed to a suitable position on the wall using a mounting bracket 3. The guide frame 104 is connected to the smelting furnace used for waste gas production. When smelting scrap aluminum, the exhaust fan 102 is turned on to extract the gas. The waste gas generated during smelting enters the cooling connection pipe 1 through the guide frame 104 and connecting hose 105, and is cooled by the heat exchange pipe 108. The cooled waste gas then enters the reaction tube 2 through the extraction pipe 101 and reacts with the reaction reagents inside the reaction tube 2. Simultaneously, liquid... The reaction reagent retains solid particles in the exhaust gas. After the exhaust gas reacts with the reaction reagent and detaches from the liquid surface, the liquid pump 202 draws the reaction reagent into the spray pipe 212.

The treated exhaust gas enters the condenser pipe 201 for cooling, causing the vaporized reaction reagent in the exhaust gas to condense and flow back into the reaction pipe 2. The exhaust gas is then monitored by the air quality monitoring component 206. If the exhaust gas meets the emission standards, the solenoid valve 209 is opened to discharge the exhaust gas or allow it to enter the next reaction pipe 2.

The water inlet pipe 103 is located at the other end of the cooling connecting pipe 1 relative to the exhaust pipe 101.

[0034] The cooling connection pipe 1 is installed on the wall surface through the mounting frame 3, and the flow guide frame 104 is connected with the smelting furnace generating waste gas. When the waste aluminum material is smelted, the air extractor 102 extracts air in the cooling connection pipe 1, so that the waste gas generated by smelting passes through the flow guide frame 104 and the connecting hose 105 into the cooling connection pipe 1. The water inlet pipe 103 pumps cold water into the heat exchange pipe 108, so that the cold water cools the high-temperature waste gas, and the hot water is discharged through the drain pipe 106.

When the exhaust separates from the liquid level, the liquid pump 202 pumps the reaction reagent into the spray pipe 212 through the liquid suction pipe 214, and sprays it out through the multiple spray heads 213, so that the exhaust contacts and reacts with the reaction reagent again. The waste liquid is discharged at a fixed time through the waste pipe 205, and the reaction reagent is supplemented at a fixed time through the feeding tube 204, so that the exhaust can fully contact with the effective components in the reaction reagent.

The exhaust is monitored by the air quality monitoring assembly 206. When the exhaust meets the emission standard, the electromagnetic valve 209 is opened to discharge the exhaust or enter the next reaction tube 2.
