Mixed-bed exchanger resin leakage cause analysis and preventive measures
The frequent resin leakage in the mixed-bed exchanger of the secondary desalination equipment of the demineralization unit of CNOOC Fudao Co.,Ltd.has caused the decline in the quality of produced water,the shortening of the water production cycle,the increase in the consumption of acid and alkali and the discharge of wastewater,the frequent maintenance of the equipment and the excessive labor intensity of the operators,and at the same time,has brought about a relatively serious impact on the normal production and supply of refined demineralized water in the demineralization unit.Therefore,this paper analyzes the causes of resin leakage from the internal components such as distribution and collection water tube,stainless steel wire-wound tube and ABS water filter cap in the mixed-bed exchanger,and puts forward a series of preventive measures and rationalization suggestions for the current production situation of the demineralization unit including refinement of the technological operation and upgrading and transformation of the equipment in order to realize the safe and stable production of the mixed-bed exchanger and supply of purified demineralized water with guaranteed quality and quantity,,and ensures"safe,stable,long life,full and excellent"operation of the demineralized water plant.
