磷酸装置酸性含氟循环冷却水系统设计

The Design of Acidic and Fluorine-Containing Recirculating Cooling Water System

磷酸生产装置的循环冷却水具有含氟、含磷 ,pH值较低 ,悬浮物含量较高、循环回水温度较高的特点。针对这些特点 ,磷酸生产装置循环冷却水系统的设计要能满足防腐、防结垢、防堵塞的要求。以使磷酸生产装置的循环冷却水系统正常运行。

The recirculating cooling water for phosphoric acid production plants is featured by low content of fluorine.low content of phosphorus,low pH value,high contents of suspended matters and high temperature of recirculating cooling water.Taking into consideration these features,the design of the recirculating cooling water system for phosphoric acid production plants shall satisfy the requirements for corrosion resistance,scaling resistance and blocking resistance so as to ensure the normal operation of the recirculating cooling water system for phosphoric acid production plants.
