Through the coordinated use of the first exhaust pump and the negative pressure fan, the first exhaust pump can be used to draw external air and inject it into the negative pressure collection cabinet, and then the negative pressure fan can be used to extract the waste gas inside the negative pressure collection cabinet, so as to circulate the air inside the negative pressure collection cabinet and reduce the harm of the waste gas to the health of the staff. Through the coordinated use of the waste gas purification box, the second gas phase purifier and the third exhaust port, the waste gas entering the purification box can be purified by the second gas phase purifier, and then drawn in by the third exhaust port under the action of the output end of the second exhaust pump, and discharged by the second air outlet, so as to purify the waste gas.
