The utility model relates to a device for treating chlorinated tail gas by ferrous sulfate, which comprises an acid pickling system, an alkali liquor cleaning system and a first water washing system, as the acid pickling system adopts a reverse spraying tower, when flue gas enters a reverse spraying pipe arranged in front of the tower, the flue gas is in contact with absorption circulating liquid sprayed from bottom to top to form a foam area; most of liquid drops and particulate matters in the flue gas can be condensed and agglomerated, then freely fall down and flow into a circulating tank at the bottom of the tower, and the flue gas enters the tower after being subjected to reverse spraying washing, so that the HCL absorption effect is improved, and the problem of nozzle blockage is solved; a byproduct ferrous sulfate or ferrous chloride can be obtained, so that the consumption of the alkali liquor is reduced. 本申请涉及一种硫酸亚铁处理氯化尾气的装置，经过酸洗系统、碱液清洗系统以及第一水洗系统，由于酸洗系统是采用逆喷塔，烟气进入塔前设置的逆喷管时，烟气与自下而上喷淋的吸收循环液接触后形成形成泡沫区域，
