Equipment for preparing ammonium sulfate by using production tail gas of gold mineral separation agent and use method of equipment

The invention provides equipment for preparing ammonium sulfate from production tail gas of a gold ore dressing agent and a using method thereof.The equipment comprises a particle adsorption tower, an ammonia gas absorption tower, a tail gas treatment tower, a tail gas incineration system and a wastewater treatment pond, and the particle adsorption tower, the ammonia gas absorption tower and the tail gas treatment tower are sequentially communicated through pipelines; air enters from the bottom of the tower, air exits from the upper part of the tower, and an air outlet is communicated with an air inlet of the next tower through a pipeline; the tail gas firstly passes through the particle adsorption tower to remove insoluble particles, then enters the ammonia gas absorption tower to react with sulfuric acid to generate ammonium sulfate, is subjected to evaporative crystallization and finally is subjected to centrifugal drying to prepare an ammonium sulfate product, and the residual tail gas is further treated
