s3, in the process that the tin ore waste is melted, gas such as sulfur dioxide is generated, sodium hydroxide solution is injected into the fixed sleeve (72) through the liquid inlet pipe (76), the gas enters the fixed sleeve (72) along the ventilation catheter (71), low-temperature cooling water is arranged in the cooling screw pipe (73), most of heat contained in the gas can be absorbed when the gas passes through the ventilation catheter (71), the situation that the surrounding environment is influenced by a large amount of heat along with the gas is avoided, the gas moves downwards along the check ring (75) to pass through the sodium hydroxide solution, and the sulfur dioxide in the gas is absorbed;
s4, enabling the gas to pass through the adsorption separation plate (74), wherein an adsorbent is arranged at the upper part of the adsorption separation plate (74) and can absorb other substances contained in the gas, and finally, the gas is discharged through the exhaust pipe (77), so that the whole exhaust device (7) has a purifying effect on the gas generated by the device.
