Experimental study on design andpurification performance of mobile welding dust purifier
Aiming at solving the problems of large volume and heavy weight of mobile welding fume purifier and poor man-machine interaction,a mobile welding fume purifier control system based on PLC was designed.The control system adopts Siemens S7-200 CPU224 PLC as the core controller,and co-operates with the PM2.5 sensor,brushless DC and 4G gateway to realize the functions of operation con-trol,operation and monitoring of the mobile welding fume purifier.The hardware selection,design,soft-ware development and configuration of the system are described in detail.The test results show that the maximum air volume of the prototype is 591.98 m3/h,the purification efficiency is 99.75％,and the prototype has a good purification effect.
