Beschreibung
Zusammenfassung:	The invention discloses an epichlorohydrin waste gas treatment method, which comprises the following steps: (1) conveying ECH waste gas to an acid pickling tower from the bottom, spraying hydrochloric acid to wash and absorb the ECH waste gas from the top of the acid pickling tower, and discharging the washed ECH waste gas from the top of the acid pickling tower to enter a next process; (2) conveying the washed ECH waste gas from the step (1) into an incinerator to be incinerated, wherein the incineration temperature is 850-1000 DEG C, and ECH is incinerated and decomposed in the incinerator to obtain incineration waste gas; and (3) quenching and cooling the incineration waste gas from the step (2) to 80-100 DEG C, sending the incineration waste gas to an alkaline washing tower from the bottom, spraying and washing the top of the alkaline washing tower with alkali liquor to absorb HCl, and discharging residual CO2 and H2O from the top of the alkaline washing tower through a chimney. After treatment, the ECH c
