Abstract


For large and medium - sized chemical companies , under normal circumstances must be matched to the circulating water system , thermoelectric system . For example : the use of a circulating water system provides water circulation so that the heat generated by the chemical reaction is removed in a timely manner , the product of chemical production in accordance with the need to get the ideal and appropriate yield and rate . The thermoelectric system high, middle and low pressure steam production , in addition to supply production device heating, to participate in the chemical reaction , there is an important task is to drive the compressor and other power equipment . The circulating water system needs to be constantly replenished fresh water , continuous circulating water sewage ; the thermoelectric system requires use of fresh water and manufacturing of demineralized water trickle continuously . Reasonable processes and equipment preparation demineralized water using reliable technology blowdown water for recycling to improve resource utilization , environmental protection is very important . Reuse of blowdown water desalination treatment , desalted water production is a desalination process , reverse osmosis desalination process and rapid development of traditional ion exchange to conduct a detailed comparative analysis of the traditional reverse osmosis pretreatment technology and ultrafiltration pretreatment process . compared to Tianjin Soda Plant Luan river water quality characteristics of the circulating water sewage water quality characteristics , program and cost calculation . The results show that : ultrafiltration, reverse osmosis system of circulating water , sewage water recycling technology , economically feasible, the ion exchange system can not be achieved . The Luan River manufacturing demineralized water system , ultrafiltration, reverse osmosis process instead of the ion exchange process , economically viable technology , with no containing acid and alkali wastewater discharge problems , and high degree of automation and other advantages . In the program , the Luan River manufacturing in addition to the concentrate brine system incorporated into the circulating water sewage water recycling system , two reverse osmosis unit , the system returns then make Luan river Manufacturing In addition to the utilization of saline water . The program transformation in addition to the brine manufacturing engineering building has played an important role in guiding the Tianjin Soda Plant in New Area , and also can be used to use the Luan river water as well as the North dryland surface water chemical companies , power companies in addition to the salt manufacturing solutions design provide a reference.
