One end of described pneumatic tube is communicated with described spark arrester; Described burner is fixed on the other end of described pneumatic tube;
Described glow heater is fixed on described pneumatic tube by described fixation kit; Described glow heater is positioned at the top of described burner; Described glow heater forms current circuit by wire and described power turn-on.
As preferably, described fixation kit comprises:
Set collar, sliding sleeve and support bar;
The bottom of described support bar is connected on described pneumatic tube by described set collar;
Described glow heater and described sliding sleeve are connected, and are set on the upper end of described support bar by described sliding sleeve;
Described sliding sleeve can be along the upper and lower slippage of described support bar; Described sliding sleeve can be fixed by screws on described support bar.
A kind of test that the utility model provides with the residual hydrogen burning device of high-temperature annealing furnace by glow heater laser heating is set, glow heater always keeps the condition of high temperature in process of the test, the residual hydrogen tail gas no matter when discharging can be lighted automatically through the glow heater of the condition of high temperature, guaranteed like this in high temperature annealing test, to discharge the safe and reliable of residual hydrogen tail gas process, the risk of effectively having avoided residual hydrogen tail gas to leak.Continuous firing after the glow heater energising of this combustion unit, without the residual hydrogen exhaust combustion process of the long-time supervision of operator, avoids operator's attention to concentrate for a long time, has reduced labour intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the residual hydrogen burning device of high-temperature annealing furnace for the test that provides of the utility model embodiment.
Fig. 2 is the schematic diagram after the residual hydrogen burning device igniting of high-temperature annealing furnace for test that the utility model embodiment provides.
Embodiment
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is elaborated.
Referring to attached Fig. 1 and 2, the residual hydrogen burning device of high-temperature annealing furnace for a kind of test that the utility model provides, comprising: for discharging delivery pipe 8, spark arrester 7, pneumatic tube 6, burner 4, fixation kit, glow heater 1 and the power supply 3 of the residual hydrogen tail gas of high-temperature annealing furnace; One end of delivery pipe 8 is communicated with the exhaust port of high-temperature annealing furnace; The other end of delivery pipe 8 is communicated with spark arrester 7; One end of pneumatic tube 6 is communicated with spark arrester 7; Spark arrester 7 is set between delivery pipe 8 and pneumatic tube 6 and can effectively prevents that Air Reverse from channeling to delivery pipe 8 and then entering in high-temperature annealing furnace, avoid high-temperature annealing furnace to blast causing the damage of personnel and equipment.Burner 4 is fixed on the other end of pneumatic tube 6; Pneumatic tube 6 vertically arranges, and burner 4 is horn-like, and burner 4 small ends are connected in the top outlet of pneumatic tube 6.Glow heater 1 is fixed on pneumatic tube 6 by fixation kit; Glow heater 1 be positioned at burner 4 outlet directly over; Glow heater 1 forms current circuit by wire and power supply 3 conductings.By conducting or the disconnection of controlling current circuit that open or close of power supply 3, and then control the heating of glow heater 1 or stop.Before on-test, to glow heater 1 energising heating, made glow heater 1 be heated to rubescent state, can guarantee like this when residual hydrogen tail gas sprays from burner 4 to be lighted by glow heater 1.
Referring to accompanying drawing 2, before test is led to hydrogen with high-temperature annealing furnace, operator will confirm that glow heater 1, in rubescent state, passes into hydrogen after the furnace temperature of annealing furnace reaches requirement, and after this, operator can observe the flame 9 of being lighted by glow heater 1.Guarantee that glow heater 1 remains the rubescent state that is heated in process of the test, so no matter when to discharge residual hydrogen tail gas and can automatically be lighted, guaranteed the safe and reliable of high-temperature annealing furnace, the risk of effectively having avoided residual hydrogen tail gas to leak.Meanwhile, only need glow heater 1 energising, glow heater, by continuous heating, without the residual hydrogen exhaust combustion process of the long-time supervision of operator, avoids operator's attention to concentrate for a long time, has reduced labour intensity.
