Description
Technical field
The utility model relates to a kind of gasification furnace supervising device.
Background technology
The pressing gas metallization processes enjoys high reputation in coal chemical technology with its plurality of advantages always.Owing to gasification installation initial designs reason, the igniting system that goes into operation lacks monitor and control facility.At present, the ultraviolet flame monitoring equipment degree of accuracy of application is not high always, and this mainly is because due to the gasification furnace position limit; Also there is how tame gasification furnace that picture pick-up device has been installed; When driving, rely on picture pick-up device to observe situation in the stove, but these method accuracys are all not high enough, and human factor is more; Be easy to generate erroneous judgement and cause unplanned parking and repeatedly igniting, thereby cause heavy economic losses.
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 gasification furnace supervising device.
The technical solution of the utility model:
A kind of gasification furnace supervising device, its special character is: comprise burner hearth monitor control mechanism and electronic ignition monitoring device; Said monitor control mechanism comprises the column hollow shell, is used for the clear glass of seal casinghousing front end; The cable passage that is provided with the monitoring instrument that is positioned at the clear glass rear and leads to the housing rear end in the said housing; Said housing comprises cooling water inlet passage, coolant outlet passage and the channel of nitrogen of concentric setting from outside to inside successively, and said cooling water inlet passage, coolant outlet passage communicate at the housing front end; Said channel of nitrogen is over against clear glass; Said cooling water inlet passage and coolant outlet passage communicate with external water source from the housing rear; Said channel of nitrogen communicates with external air source from the housing rear; Said electronic ignition monitoring device comprises 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; Said power supply adopts the 220V AC power of firing circuit.
Above-mentioned detecting instrument comprises at least one ultraviolet flame monitor.
Above-mentioned detecting instrument comprises a camera head.
Above-mentioned clear glass is a double glazing, and said channel of nitrogen communicates with the interlayer of double glazing.
The advantage that the utility model had:
Because original igniter burner passage is over against flame kernel; Therefore flame monitoring apparatus stretches into behind the burner hearth over against flame kernel; The flame monitoring instrument can monitor the burner hearth combustion case accurately; And because camera head is in burner hearth inside, therefore can see the overall picture of flame intuitively, effectively raise the security of gasification installation start-up burner hearth.Greatly reduce the probability that contingency takes place, well increased the security and stability and the economy of gasification installation start-up.Because igniter adopts the sparking of high energy electricity, has 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.
Description of drawings
Fig. 1 is the supervising device scheme of installation of the utility model;
Fig. 2 is the supervising device structural representation of the utility model;
Fig. 3 is the electronic ignition monitoring device circuit theory diagrams of the utility model;
Wherein: 1-burner hearth, 2-monitor control mechanism, 3-propulsive mechanism, 4-fire inspection signal picker, 5-detecting instrument, 6-clear glass, 7-cable passage, 8-housing, 9-cooling water inlet passage, 10-coolant outlet passage, 11-channel of nitrogen.
The specific embodiment
Along with the use of novel all-in-one startup burner, original igniter burner is stopped using, and this has just vacated an effective passage for gasification furnace, and the utility model occurs just on this basis.
As shown in Figure 1, the utility model comprises burner hearth monitor control mechanism 2 and electronic ignition checkout gear, and monitor control mechanism profile and igniter burner are similar, stretch into burner hearth 1.The utility model adopts many sleeve type structures, and the outermost layer chuck is a cooling water inlet passage 9, and the internal layer chuck is the coolant outlet path 10; Constantly there is cooling water to flow through during work, housing 8 outer surfaces are remained in the safe temperature range, effectively promoted the adaptive capacity of monitor control mechanism in high temperature and high pressure environment; Housing head adopts the double-layer transparent glass design; And design nitrogen protection unit, nitrogen leads to head by the channel of nitrogen 11 of enclosure interior, constantly washes away head glass; The one, play and reduce glass two ends pressure reduction; Effective lifting device anti-pressure ability, the 2nd, head glass is cooled off in real time, effectively improve the adaptive capacity of head in high-temperature burner hearth; As shown in Figure 2, flame monitoring apparatus is installed in the glass rear end, because the space is sufficient, therefore two ultraviolet flame monitors can be installed, and simultaneously a camera head can also be installed, and according to actual conditions, can also change the kind and the quantity of monitoring instrument.The cable of detecting instrument 5 leads to the outside through the cable passage in the channel of nitrogen 7, sends into fire inspection signal picker 4, control DCS (Distributed Control System) in finally sending into.As shown in Figure 3, 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.
