After the absorption liquid in the cavity of the reactor body 1 submerges the ventilation and stirring structure 3, the hydrogen chloride waste gas enters from the tail gas inlet, passes through the air guide pipe 11 and the ventilation and stirring structure 3 in sequence, and the air guide pipe 11 discharges the hydrogen chloride waste gas into the absorption liquid below the cavity of the reactor body 1, achieving air intake from the bottom and sufficient contact with the absorption liquid; the ventilation and stirring structure 3 diffuses the hydrogen chloride waste gas in the air guide pipe 11 to the surrounding areas of the cavity of the reactor body 1 through the exhaust holes 311 of the fan blades 31, and the fan blades 31 rotate under the reaction of the blown air flow, performing a stirring function;
