Research on Intelligent Transformation of Mobile Membrane Separation Nitrogen Plant Based on PLC
Based on the problems of low degree of intelligent automation and high temperature before entering the membrane tube in DM-1000/10(L)mobile membrane separation nitrogen generator,an intelligent control scheme with PLC as the core is proposed.The intelligent control scheme can carry out in situ monitoring of the display,Modbus communication with the air compressor to achieve comprehensive monitoring of the nitrogen production process of the nitrogen plant,and the results of practical application show that:the mobile membrane separation nitrogen plant can greatly improve the nitrogen production accuracy,nitrogen production efficiency,the degree of automation of the equipment operation,and reduce the labour intensity of the staff and the cost of nitrogen production after the intelligent transformation based on PLC.
