Abstract
The invention relates to an electronic ignition detection device of a startup burner. The electronic ignition detection device of the startup burner comprises a power supply, a signal collector, a signal amplifier and a signal detector, and the signal collector, the signal amplifier and the signal detector are connected in sequence. The signal collector is used for a current signal of a sensitive ignition circuit, sends an output ignition signal to the signal amplifier, the ignition signal which is amplified by the signal amplifier is sent to the signal detector, the signal detector is used for analyzing and judging the ignition signal, converting a judgment result into a switch signal, sending the switch signal to a programmable logic controller (PLC) control system and arranging a safe interlock. The electronic ignition detection device of the startup burner solves the technical problems that the existing detection equipment is low in precision and misjudgments are easily made, greatly reduces complexity of practical operation, improves safety of integral startup burner in ignition to a great extent, effectively saves huge expense of ignition delay caused by accidents, and meanwhile saves huge expense of a plurality of ignitions.
Description
Technical field
The present invention 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 coal gasification apparatus in security and the economy of start-up with its high reliability.At present startup burner igniting is all to observe situation in stove by 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, due to 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 approaches a hundred per cent.Thus, as long as it is working properly to monitor the high energy electricity sparking of head, with regard to the effective indirect monitoring startup burner head ignition situation of energy, and can reach very high accuracy rate.
Summary of the invention
Not high in order to solve existing monitoring equipment accuracy, easily produce the technical problem of erroneous judgement, the invention provides a kind of startup burner electronic ignition monitoring device.
Technical solution of the present invention:
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; Described 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 described signal amplifier amplifies is sent into signal detector, described signal detector is used for ignition signal is analyzed judgement, and judged result is converted to switching signal sends into the PLC control system and safety interlocking is set.
The above-mentioned power acquisition 220V AC power of firing circuit.
The present invention has advantages of:
1, because igniter adopts the sparking of high energy electricity, only have 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 present invention avoids the hazards that high temperature and high pressure environment brings cleverly by the monitoring of system power indirectly being monitored the working condition of startup burner head point firelock, greatly reduces the complexity of practical operation.
2, the development of real-time monitoring system of the present invention is in order to make up the deficiency of integrated startup burner security monitoring aspect, thereby largely improves the security of integrated startup burner when igniting.Effectively save the enormous expenditure that causes firing delay due to contingency, also saved the repeatedly enormous expenditure of igniting simultaneously.
Description of drawings
Fig. 1 is startup burner electronic ignition monitoring device circuit theory diagrams of the present invention.
The specific embodiment
As shown in Figure 1, igniter input 220V alternating current is transported to spark lever after by built-in high energy transformer, voltage being risen to 2500V, is provided with corresponding protective resistance and electric capacity in the loop.Because spark lever adopts insulation autonomous channel design, therefore only have when the burner normal ignition, just having electric current in firing circuit produces, this moment, the signal picker of apparatus of the present invention will receive current signal, and signal is transported to signal amplifier, the signal entering signal detector that is exaggerated is after the judgement of PLC system, 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; Described 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 described signal amplifier amplifies is sent into signal detector, described signal detector is used for ignition signal is analyzed judgement, and judged result is converted to switching signal sends into the PLC control system and safety interlocking is set.
