Description
Technical field
The invention belongs to technical field of industrial dust removal, especially a kind of redundancy control system being blown for pulse valve of bag-type dust collector.
Background technology
The soot cleaning system of sack cleaner is made up of cloth bag, gas tank and pulse valve, the gas tank that sack cleaner is not waited according to the settable quantity of its dedusting area difference, needs each gas tank that a number of pulse valve is housed according to design.Flue gas is flowed out by the outer surface of cloth bag via cloth bag from cloth sack during normal operation, dust is attached to the outer surface of cloth bag, pulse valve is opened during deashing, and neat stress blows the inwall in cloth bag, cloth bag expansion via pulse valve, after last for several seconds, pulse valve is closed, and cloth bag recovers, by expanding, recovering this process, the dust of cloth bag outer wall is shaken off in ash bucket, realizes 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.Being blown common control method has two kinds：The first, the injection for realizing pulse valve by programmable controller is controlled, if such a method programmable controller is configured using low, middle-end, redundancy, controller can not be realized once breaking down, injection system will be unable to work, sack cleaner is caused to stop transport, its system reliability is poor；If programmable controller uses redundant configuration, although a controller breaks down, and another can make pulse valve continue to be blown, but such a scheme must be that high side controller can realize redundancy, and fund input is high；Sack cleaner operation need to be stopped by changing programmable controller, it is impossible to realize online change；Second, injection control is realized by pulse control instrument, once such a method pulse control instrument is damaged, injection system can not work, and sack cleaner is out of service, it is impossible to realize online change；The usual operation pressure pattern of sack cleaner according to the change of pressure difference, it is necessary to adjust injecting velocity, and when pressure difference pattern breaks down using time series pattern, pulse control instrument only has time series pattern, and control model is single.
The content of the invention
Instant invention overcomes above-mentioned defect, solving can not online be changed using low, middle-end programmable controller poor reliability, high programmable controller redundant configuration cost input, programmable controller or pulse control instrument, individually use the single defect of pulse control instrument control model to be used for the redundancy control system that pulse valve of bag-type dust collector is blown there is provided a kind of.
A kind of redundancy control system being blown for pulse valve of bag-type dust collector of the present invention is made up of pulse control instrument, miniature relay, programmable controller, matrix circuit.Pulse control instrument poppet control output signal is isolated through miniature relay, and programmable controller row selected control output signal is isolated through miniature relay, and the passive opened point parallel connection of miniature relay of the two reference numeral is followed by the corresponding gas tank number input of matrix circuit.Pulse control instrument pulse valve control output signal is isolated through miniature relay, programmable controller column selection control output signal is isolated through miniature relay, and the passive opened point parallel connection of miniature relay of the two reference numeral is followed by pulse valve number input in matrix circuit gas tank.The injection of pressure difference Schema control pulse valve is used by programmable controller under normal circumstances, programmable programmable controller need not shut down when breaking down and control pulse valve blowing by pulse control instrument.
The beneficial effects of the invention are as follows programmable controller incorporates matrix circuit simultaneously with pulse control instrument, and programmable programmable controller need not shut down when breaking down and control pulse valve blowing by pulse control instrument, realize Redundant Control, it is ensured that system reliability.
Programmable controller and pulse control instrument Redundant Control pulse valve blowing, injection system reliability are high, and programmable controller need not use high-end redundant configuration, configured using low, middle-end, can greatly save fund input.
Pulse control instrument is two power supplies separated with programmable controller, and faulty equipment power supply can be disconnected when one is faulty, is changed, and by another realization injection control, realizes online change.
Programmable controller and pulse control instrument incorporate pulse valve blowing control system simultaneously, that is, maintain the advantage that programmable controller adjusts injecting velocity according to pressure difference, maintain that pulse control instrument is easy to maintenance, change convenient advantage again.
