Description
The utility model belongs to a kind of igniter that is used for the petrochemical plant heating furnace.At present, most of heating furnace igniters that petrochemical plant is used do not have electronic ignition function, in the ignition operation process, need come firing point firearm (rifle) with oilcloth, torch by artificial, then this igniter (rifle) is sent in the fire hole of heating furnace below, removed to light the main nozzles in the burner hearth again.In addition, though some igniters have electronic ignition function, but part still is weak on gas circuit structure, carbon deposit is serious around causing burner, and in the design of spray point, also exist electric insulation apart from short major defect, therefore, this kind igniter the carbon deposit short circuit will occur after using several times, causes component to damage and scraps.
Task of the present utility model is to provide a kind of anti-carbon deposit formula heating furnace electric igniter, and this kind igniter has solved igniting automation and anti-carbon deposit short circuit problem preferably, utilizes this igniter can overcome the deficiency of existing heating furnace igniter.
The utility model is to realize like this.This igniter comprises circuit and gas circuit two parts.By igniting pin 1, go up dielectric support 2, outer tube 3, mixing chamber 4, flexible pipe 5, intake valve 6, high pressure generator 7, fixedly chuck 8, nut 9, air inlet pipe 10, high-voltage line 11, down insulating bar 12, interior pipe 13, prevent that carbon deposit cover cap 14, burner 15 and circuit part 16 form.Its assembling, architectural feature are as follows: pipe 13 in being provided with in the outer tube 3, interior pipe curves burner 15 in 13 tops, its below is connected with anti-carbon deposit cover cap 14 by bolt, in the pipe upper and lower part be set with dielectric support 2 and following insulating bar 12 respectively, weld out the igniting pin 1 of vertical and a level on the interior pipe respectively with the outer tube upper portion side wall; Air inlet pipe 10 is connected with fixing chuck 8 by nut 9, air inlet pipe 10 lower ends are connected with flexible pipe 5, and flexible pipe 5 other ends are connected with intake valve 6 and Device in Gas pipeline, and air inlet pipe 10 tops are set with mixing chamber 4, mixing chamber 4 tops are connected with outer tube 3 lower ends by screw thread, and the bottom is welded fixedly on the chuck 8; High pressure generator 7 one terminations go out high-voltage line 11, and high-voltage line 11 passes mixing chamber 4 and welds mutually with interior pipe 13 tube walls with following insulating bar endoporus, and the other end links to each other with circuit part 16 in being installed in distribution box.The course of work of this igniter is as follows: the Device in Gas from systematic pipeline enters interior pipe 13 by the endoporus on the following insulating bar 12 after intake valve 6, flexible pipe 5 enter mixing chamber 4 and air mixes, finally arrive burner 15.At this moment, press the starting button QA of circuit part, produce discharge spark on the pin 1 of then lighting a fire, electric spark is lighted gaseous mixture immediately, and self lights a fire igniter successfully.If igniter is worked under portable mode, then can be inserted in the fire hole of heating furnace below, open main burner oil-feed (gas) valve and can light main burner; If igniter is fixed installation, then can be fixed on the heating furnace fire hole by fixing chuck 8, open main burner intake valve, the flame of igniter burner is lighted heating furnace master burner immediately.This ignitor circuit partly constitute and operation principle as follows: control loop terminal a-n connects the 220V AC power, press starting button QA after, electric current is through terminal a, again through automatic control normally closed contact YB1, the normal YB of making war
2, stop button TA, normally opened contact C, to contactor coil C, arrive terminal n formation start loop at last.When control loop gets electric work, major loop 220V input current is through terminal A, fuse RD, main contact C, arrive high pressure generator B again, come out from high pressure generator B coil, electric current is got back to terminal N, thereby in secondary coil, produce the 7000-8000VAC high voltage, and output to and make it gap discharge on the pipe electrode igniting pin in the igniter and produce electric spark.When igniting finishes, in the time of need stopping the electricity sparking, press stop button TA and get final product.Instrument contact YB
1, YB
2The Long-distance Control and the interlocking that can be used as robot control system(RCS).
The utility model has adopted anti-carbon deposit, short circuit protective igniting needle construction in design, electric ignition is not subjected to the restriction of outdoor climate and manual igniting, be convenient to match with program control, interlocking, utilize it can finish the heating furnace ignition operation more rapidly, conveniently, safely, reliably, avoid the generation of burn personnel accident in the furnace operating effectively, all significant for raising refinery's heating furnace equipment and safe operation thereof, be suitable for and apply.This igniter can be used for stove or accident blowing out igniting.Extract out from stove if after igniting igniter gas intake valve cuts out the back, then this igniter only plays ignition action; If do not close intake valve, it not to be withdrawn from stove yet, it just moves with heating furnace master burner, plays " normal bright lamp " effect as auxiliary burning nozzle.
