Cause Analysis and Improvement Measures for Blockage of Liquid Nitrogen Washing Cold Box
[Purposes]To reduce the probability of blockage in liquid nitrogen wash cold boxes,improve the reliability and performance of liquid nitrogen wash cold boxes,enhance their work efficiency and stability,reduce maintenance and cleaning costs,ensure their long-term stable operation,and provide technical support for the design and manufacture of more efficient and reliable liquid nitrogen wash cold boxes,it is necessary to propose a study on the causes of blockage in liquid nitrogen wash cold boxes and improvement suggestions.[Methods]The causes of blockage in the liquid nitrogen washing cold box were analyzed from three main aspects:equipment problems,improper operation,and external environmental impact.Targeted improvement suggestions were proposed from four perspectives:liquid nitrogen management,pipeline renovation and optimization,impurity control,and temperature control.[Findings]In practical applications,the proposed improvement suggestions effectively reduced the fre-quency of blockage problems in liquid nitrogen washing cold boxes.[Conclusions]The study can deeply analyze the causes of blockage in liquid nitrogen washing cold boxes and propose specific im-provement suggestions,providing strong support for the design and use of cooling equipment in related industries.
