[0028] Working principle: Industrial hazardous waste is added to the combustion chamber 2 through the feed pipe 3. Sufficient treatment reagent is added to the purification chamber 7. The burner 14 is turned on to evaporate the waste entering the combustion chamber 2. The evaporated gas flows into the purification chamber 7 through the first gas delivery pipe 5. The gas mixes and reacts with the treatment reagent. The pump 19 is turned on to draw the treatment reagent and deliver it through the water pipe 21 to the nozzle 20. The treatment reagent is then atomized and sprayed out through the nozzle 20, reacting with the gas in the purification chamber 7 to better remove harmful substances. The treatment reagent also cools the gas. The purified gas then reacts with the filter assembly 22. The gas is filtered and then enters the exhaust pipe 9. The gas detection probe 10 detects the gas to be emitted in the exhaust pipe 9. If the gas passes the test, the first solenoid valve 11 is opened to discharge the gas. If the gas fails the test, the second solenoid valve 13 is opened to send the gas into the combustion chamber 2 through the second gas delivery pipe 12 for evaporation treatment again, thereby improving the evaporation treatment effect of industrial hazardous waste.
