Description
Technical field
The invention belongs to technical field of industrial dust removal, a kind of redundancy control circuit for pulse valve of bag-type dust collector winding-up.
Background technology
The soot cleaning system of sack cleaner is made up of cloth bag, gas tank and pulse valve, and sack cleaner can arrange, according to its dedusting area difference, the gas tank that quantity does not waits, and needs each gas tank equipped with a number of pulse valve according to design.Time properly functioning, flue gas is flowed out from cloth bag mouth via cloth bag by the outer surface of cloth bag, dust is attached to the outer surface of cloth bag, during deashing, pulse valve is opened, and neat stress blows the inwall at cloth bag via pulse valve, and cloth bag expands, after last for several seconds, pulse valve cuts out, and cloth bag recovers, through expanding, recovering this process, the dust of cloth bag outer wall is shaken off in ash bucket, it is achieved the purpose of cloth bag deashing.The reliability of injection system directly influences whether sack cleaner can run, and is the key link of bag-type dust.Common control method of jetting has two kinds: the first, the winding-up being realized pulse valve by Programmable Logic Controller controls, if this kind of method Programmable Logic Controller uses low, middle-end configuration, redundancy can not be realized, controller once breaks down, injection system will be unable to work, causes sack cleaner to stop transport, and its system reliability is poor；If Programmable Logic Controller uses redundant configuration, although a controller breaks down, and another can make pulse valve continue winding-up, but this kind of scheme must be that high side controller can realize redundancy, and fund input is high；Change Programmable Logic Controller and need to stop sack cleaner operation, it is impossible to realize online replacing；The second, is realized winding-up by pulse control instrument and controls, and this kind of method once pulse control instrument damages, and injection system can not work, and sack cleaner is out of service, it is impossible to realize online replacing；Sack cleaner generally runs pressure reduction pattern, needs the change according to pressure reduction to adjust injecting velocity, uses time series pattern when pressure reduction pattern breaks down, and pulse control instrument only has time series pattern, and control model is single.
Summary of the invention
Instant invention overcomes the defect of above-mentioned existence, solve and use low, middle-end Programmable Logic Controller poor reliability, Programmable Logic Controller redundant configuration cost to put into high, Programmable Logic Controller or pulse control instrument can not be changed online, individually uses the defect that pulse control instrument control model is single, it is provided that a kind of redundancy control circuit for pulse valve of bag-type dust collector winding-up.
A kind of redundancy control circuit for pulse valve of bag-type dust collector winding-up of the present invention is made up of pulse control instrument, miniature relay, Programmable Logic Controller, matrix circuit.Pulse control instrument promotes valve control output signal isolates through miniature relay, and Programmable Logic Controller row selected control output signal is isolated through miniature relay, and the passive normally opened parallel connection of miniature relay of the two reference numeral is followed by the gas tank number input that matrix circuit is corresponding.Pulse control instrument pulse valve controls output signal isolates through miniature relay, Programmable Logic Controller column selection controls output signal and isolates through miniature relay, and the miniature relay passive normally opened some parallel connection of the two reference numeral is followed by pulse valve number input in matrix circuit gas tank.Used the winding-up of pressure reduction Schema control pulse valve under normal circumstances by Programmable Logic Controller, need not shut down when programmable controller able to programme breaks down and be controlled pulse valve blowing by pulse control instrument.
The invention has the beneficial effects as follows, Programmable Logic Controller and pulse control instrument incorporate matrix circuit simultaneously, need not shut down and be controlled pulse valve blowing by pulse control instrument, it is achieved that Redundant Control, it is ensured that system reliability when programmable controller able to programme breaks down.
Programmable Logic Controller and pulse control instrument Redundant Control pulse valve blowing, injection system reliability is high, and Programmable Logic Controller need not use high-end redundant configuration, uses low, middle-end to configure, can be greatly saved fund input.
Pulse control instrument and Programmable Logic Controller are two separate power supplies, when one is faulty can open failure device power supply (DPS), be replaced, another realize winding-up and control, it is achieved change online.
Programmable Logic Controller and pulse control instrument incorporate pulse valve blowing control system simultaneously, i.e. maintain Programmable Logic Controller and adjust the advantage of injecting velocity according to pressure reduction, maintain again that pulse control instrument is easy to maintenance, change convenient advantage.
