[0030] The industrial waste gas enters from the collection port. The iron, nickel, and cobalt metal particles contained in the waste gas are adsorbed by the electromagnets inside the side wall of the metal adsorption box. After adsorption for a certain period of time, when the power is cut off, the metal particles can fall onto the inclined collection plate. When a certain weight is accumulated on its surface, the inclined collection plate will automatically sink, and then the movable contact block contacts the trigger block, causing the alarm to start, reminding the staff. Then, the drive motor is started. The drive motor drives the slider and pushes the connecting scraper to push the metal particles on the inclined collection plate towards the leakage port. Then, the waste residue particles fall into the metal collection box. The waste gas after being treated enters the spray cylinder. The mist generated by the spray nozzles in the spray cylinder makes full contact with the waste gas. Part of the spray that adsorbs the waste gas particles falls onto the inner panel of the spray cylinder under the action of gravity, enters the confluence box through the filter screen, and then enters the sedimentation tank. The waste gas passing through the spray cylinder then enters the filter box, is fully adsorbed by the multi-layer filter elements during intake, and then enters the exhaust cylinder and is discharged through the exhaust fan.
