Abstract
The utility model relates to an electronic ignition monitoring device for a start-up burner. The device comprises a power supply, and a signal acquisition device, a signal amplifier and a signal detector which are connected in sequence, wherein the signal acquisition device is used for sensing a current signal of an ignition circuit; an ignition signal output by the signal acquisition device is sent to the signal amplifier; the ignition signal amplified by the signal amplifier is sent to the signal detector; and the signal detector is used for performing analytical judgment on the ignition signal, converting a judgment result into a switch signal, sending the switch signal to a programmable logic controller (PLC) system and setting safety interlocking. By the device, the technical problems that the conventional monitoring equipment is low in accuracy and misjudgment is easily caused are solved, the complexity of actual operation is greatly reduced, the safety of the integrated start-up burner during ignition is improved to a large extent, the high cost of ignition delay caused by an accident is effectively saved, and the high cost of repeated ignition is saved.
Description
Technical field
The utility model relates to a kind of gasification furnace supervising device.
Background technology
As one of nucleus equipment of pressing gas metallization processes, integrated startup burner effectively raises security and the economy of coal gasification apparatus in start-up with its high reliability.Startup burner igniting at present all is to observe situation in the stove through picture pick-up device, and this method is not because igniting starting stage fire box temperature is not high, during the burner ignition flame brightness less, be easy to produce erroneous judgement and cause unnecessary jumping car, cause heavy economic losses.Integrated startup burner adopts the sparking of high energy plasma because the oil circuit atomizing of burner good mixing own, therefore be full of when mixing aerosol when the burner head, as long as just have hard flame burner to occur can ignition, success rate is near a hundred per cent.Thus, as long as it is in proper working order to monitor the high energy electricity sparking of head, effective indirect monitoring startup burner head ignition situation just, and can reach very high accuracy rate.
Summary of the invention
Not high in order to solve existing monitoring equipment accuracy, be easy to generate the technical problem of erroneous judgement, the utility model provides a kind of startup burner electronic ignition monitoring device.
The technical solution of the utility model:
A kind of startup burner electronic ignition monitoring device, its special character is: comprise power supply and the signal picker, signal amplifier and the signal detector that connect successively; Said signal picker is used for the current signal of sensitive spot ignition circuit; The ignition signal of its output is sent into signal amplifier; Ignition signal after said signal amplifier amplifies is sent into signal detector; Said signal detector is used for ignition signal is carried out analysis and judgement, and converts judged result into switching signal and send into PLC control system and safety interlocking is set.
Above-mentioned power supply adopts the 220V AC power of firing circuit.
The advantage that the utility model had:
1, because igniter adopts the sparking of high energy electricity, have only when head gas is punctured by high voltage electric energy, burning torch just can produce hard flame, and this moment, the circuit system conducting had a large amount of electric currents to pass through in the loop.The utility model passes through the working condition to the monitoring indirect monitoring startup burner head point firelock of system power, and the hazards that high temperature and high pressure environment brings are avoided cleverly, greatly reduces the complexity of practical operation.
2, the development of the utility model real-time monitoring system is in order to remedy the deficiency of integrated startup burner security monitoring aspect, thereby largely improves the security of integrated startup burner when igniting.Effectively saved because contingency causes the enormous expenditure of firing delay, also saved the repeatedly enormous expenditure of igniting simultaneously.
Description of drawings
Fig. 1 is the utility model startup burner electronic ignition monitoring device circuit theory diagrams.
The specific embodiment
As shown in Figure 1, igniter input 220V alternating current is transported to spark lever after through built-in high energy transformer voltage being risen to 2500V, is provided with corresponding protection resistance and electric capacity in the loop.Because spark lever adopts the design of insulation autonomous channel, therefore has only when the burner normal ignition, just have electric current in the firing circuit and produce; This moment, the signal picker of the utility model device will receive current signal; And with signal conveys to signal amplifier, the signal entering signal detector that is exaggerated is after the PLC system is judged; Export corresponding switching signal to middle control DCS (Distributed Control System) system, make corresponding actions for the gasification installation central control system.
Claims (2)
1. a startup burner electronic ignition monitoring device is characterized in that: comprise power supply and the signal picker, signal amplifier and the signal detector that connect successively; Said signal picker is used for the current signal of sensitive spot ignition circuit; The ignition signal of its output is sent into signal amplifier; Ignition signal after said signal amplifier amplifies is sent into signal detector; Said signal detector is used for ignition signal is carried out analysis and judgement, and converts judged result into switching signal and send into PLC control system and safety interlocking is set.
2. startup burner electronic ignition monitoring device according to claim 1 is characterized in that: said power supply adopts the 220V AC power of firing circuit.
