PURIFYING APPARATUS OF COKE OVEN GAS AND PURIFYING METHOD OF COKE OVEN GAS

摘要

A hydrogen sulfide capture tower capable of collecting hydrogen sulfide; Ammonia collection tower capable of collecting ammonia; A coke oven gas supply unit selectively supplying a coke oven gas to the hydrogen sulfide collection tower and the ammonia collection tower through a first gas supply pipe connected to the hydrogen sulfide collection tower and a second gas supply pipe connected to the ammonia collection tower; And an agricultural ordinal water supply unit for selectively supplying agricultural ordinal water to the hydrogen sulfide collection tower and the ammonia collection tower through an agricultural ordinal water supply pipe connected to the hydrogen sulfide collection tower and a bypass agricultural ordinary water supply pipe connected to the ammonia collection tower. A coke oven gas purification device is introduced.
