| Abstract: | In this paper,the work principle of Abio-membrane Filtration Dust-cleaner developed lately and its control demands were described,and considering the characteristics of this dust-cleaner,the PLC control system was designed to overcome the disadvantages of former contactor and relay control system,such as electromagnetic valve mal-operation,being easy to damage flowmeter,being inconvenient to set or modify technical parameters,etc.It is proved that the PLC control system obtains preferable control effects than the former. |
