As everyone knows, contain a large amount of dust and lime-ash in waste gas, if not processing, enter atmosphere, can bring pollution to atmosphere.Therefore, the waste heat in utilizing waste gas, for when boiler heats, also needs process the dust in waste gas and lime-ash.For removing dust and the lime-ash in waste gas, usually all be furnished with multistage Machine for cleaning-out ash on every waste heat boiler, in the time of at most, nearly more than ten grades of the Machine for cleaning-out ash that uses on every boiler.And be the working condition of effectively controlling Machine for cleaning-out ash, with regard to needing, the machine operation situation in Machine for cleaning-out ash is controlled.At present, the method for the working condition of Machine for cleaning-out ash being controlled is all to be equipped with a cover size control system on every Machine for cleaning-out ash.Owing to all being equipped with a cover size control system on every Machine for cleaning-out ash, not only the operation circuit more complicated, occupy space larger, and debugging is got up cumbersome, and the material that needs is many, and production cost is higher., owing to all being equipped with a cover size control system on every Machine for cleaning-out ash, during operation, need to complete in front of every Machine for cleaning-out ash again, the operating personnel that not only need are many, inefficiency.And automaticity is not high.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of waste heat boiler Machine for cleaning-out ash automatic control system.Adopt this system, but the simplified control system structure, reduce production costs, increase work efficiency and automaticity.
, for addressing the above problem, take following technical scheme:
Waste heat boiler Machine for cleaning-out ash automatic control system of the present invention comprises at least two controlled unit, and described controlled unit contains ash disposal motor, relay, the first contactor and the second contactor and isolating switch.Wherein: the leading-out terminal of described relay is connected with the end of incoming cables of ash disposal motor, the end of incoming cables of described relay is connected with the leading-out terminal of the second contactor with the first contactor respectively, the end of incoming cables of the first contactor and the second contactor is connected with the leading-out terminal of described isolating switch, and the end of incoming cables of described isolating switch is connected with the end of incoming cables of power supply busbar.Be characterized in also comprising: be connected by Ethernet between central processing unit and centralized control room, described central processing unit and centralized control room, to be used for carrying out Long-distance Control and signal feedback that centralized control is indoor to central processing unit.At least two group forward control ends, counter-rotating control end, forward operation feedback end, counter-rotating operation feedback end and fault-signal input end are arranged on described central processing unit, and described forward control end, counter-rotating control end, forward operation feedback end, counter-rotating operation feedback end and fault-signal input end are connected with main story start end, the counter-rotating start end of the second contactor, the switching signal feedback end of the first contactor, the switching signal feedback end of the second contactor and the switching signal feedback end of relay of the first contactor in a controlled unit respectively.
Take such scheme, have the following advantages:
Can be found out by such scheme,, because the present invention contains central processing unit and centralized control room, be connected by Ethernet between described central processing unit and centralized control room, to be used for carrying out Long-distance Control and signal feedback that centralized control is indoor to central processing unit.At least two group forward control ends, counter-rotating control end, forward operation feedback end, counter-rotating operation feedback end and fault-signal input end are arranged on described central processing unit, and described forward control end, counter-rotating control end, forward operation feedback end, counter-rotating operation feedback end and fault-signal input end are connected with main story start end, the counter-rotating start end of the second contactor, the switching signal feedback end of the first contactor, the switching signal feedback end of the second contactor and the switching signal feedback end of relay of the first contactor in a controlled unit respectively.Like this, multistage Machine for cleaning-out ash shares a cover control system, has not only simplified operation circuit, has dwindled and has occupied space, and debugging is got up also than being easier to, and the material that needs is few, thereby has reduced production cost., because multistage Machine for cleaning-out ash shares a cover control system, during operation, only need can control every Machine for cleaning-out ash by centralized control room on host computer again, needn't arrive every Machine for cleaning-out ash front operation, not only reduced operating personnel, and improved work efficiency.In addition, only need during due to operation can control the working condition of every Machine for cleaning-out ash by centralized control room on host computer, greatly improved the automaticity that the Machine for cleaning-out ash working condition is controlled.
