In view of the problems existing in the production equipment and operation process of iron brine solution treatment agent,the type of reactor,the heat exchange and cooling system,the gas pipeline static elimination system,air chamber pres-sure measurement and control system,and the removal and absorption system of nitrogen oxides after the reaction has been engineering explored.The results showed that the reaction time of each batch was about 2.5 h.The temperature in the produc-tion process of ferric chloride with a mass fraction of 38% did not exceed 80 ℃.There was no pipeline explosion accident and no nitrogen oxide escapes during the storage,transportation and use of the product.Research promoted the safer and more efficient production process of the iron brine treatment agent manufacturing industry.
