Abstract:? According to the current situation of the dust removing plant and technological requirement of the domestic steel industry, aim at the opposite-blowing pulse packet type dust precipitator that employ extensively, adopt high performance PLC to realize the operation control. This text has mainly introduced the realization of the digital output matrix of PLC system and the method of opposite-blowing pulse control, and has introduced the advantage of this system briefly.
Key words: PLC? Opposite-blowing pulse? Packet type dust precipitator
