Deaminizing and dewatering technology and special device for sodium persulfate (salt) synthetic fluid

The invention belongs to the technical field of sodium persulfate (salt) preparation, and particularly discloses a deaminizing and dewatering technology and a special device for sodium persulfate (salt) synthetic fluid. According to main technical schemes, air heated to 80-200 DEG C by an air heater passes through an air distributor arranged in a reaction still, then heat is uniformly and quickly transferred to reaction liquid, so that ammonia and moisture in the reaction liquid are quickly evaporated, separated ammonia gas enters an ammonia recovery tower through a gas pipeline, is circularly absorbed by mother liquid containing dilute sulphuric acid to become ammonium sulfate mother liquid and then the ammonium sulfate mother liquid enters a sodium persulfate electrolysis system. The special device has the characteristics of simple structure and convenience for operation; side reactions can be reduced through deaminizing and dewatering by utilizing the device, so that the high temperature decomposition poss
