Description
Technical field
The utility model relates to a kind of burning torch, particularly relates to a kind of radiation pipe burner tip burning torch, belongs to Thermal Equipment technical field.
Background technology
Radiant tube heating technique based on indirect principle efficiently avoid oxidation and the decarburization on heated object surface; for heat-treating the condition of creating under protective atmosphere; burning gases and product pollution can not be caused to affect product quality, be widely used in requiring high occasion to product quality.Radiation pipe burner tip is the core component of radiation tube heater, due to the restriction of raying pipe caliber, radiation pipe burner tip combustion space close and narrow, burner smooth ignition is a difficulties of radiation tube heater design, it is an important performance indexes of radiation pipe burner tip, direct affect production process security, stability and economy, be also the current radiation pipe burner tip aspect that emerged in operation failure problems is maximum at the scene.
Early stage radiation pipe burner tip sparking mode is divided into manual ignition and automatic ignition two kinds, and along with improving constantly of industrial furnace automatic technique, current radiation pipe burner tip generally adopts automatic ignition.The main burner of automatic ignition radiant tube is divided into again two kinds of sparking mode usually, and a kind of automatic ignition adopts ignitor directly to light a fire to main burner, monitored main burner flame by ignitor.In ignitor design, usually adopt ceramics bracket by electrode supporting in steel pipe, strike sparks by wire electrode and A-frame or air-distributing disc wall at electrode tip, ignite main burner.It is not high to there is ignition success rate in this kind of sparking mode, and burner runs that Flame monitoring is unstable, the major defect of the easy loss of electrode.Another kind of automatic ignition is then add igniter burner (burning torch) to main burner, igniter burner is arranged space gas blender, ignitor, swirl-flow devices etc., igniter burner passes into separately air, coal gas, by ignitor is ignited after being mixed by blender.Igniter burner uses as ever-burning flame, and ignite and burn main burner, control system is monitored igniter burner.In this method, the igniting reliability of main burner and operation stability complete the structural design depending on burning torch.And burning torch is exactly in fact the burner of a low discharge, there is the FAQs such as ignition success rate is not high, flame monitoring is unstable, the easy loss of electrode equally.
The patent of invention of publication number CN101900341A discloses a kind of ignitor being applicable to multiple radiation pipe burner tip, be rotor foremost, wire electrode passes and fixes with rotor from rotor, electrode is than outside coated insulation earthenware, electrode tube right-hand member permanent plant has the sparking A-frame forming the adjustable sparking structure of spacing with rotor, the manhole that insulating ceramics pipe separates carriage center from sparking three passes through and locates fixing, electrode tube left end is fixedly connected with connector, electrode catheter is installed on outside electrode tube, right-hand member is connected with burner combustion chamber electrode mounting hole, electrode erection joint left end is connected with connector, left end is provided with electrode tip.This patent is surrounded by adopting total travel insulation to ignitor silk, avoids limit wall sparking and wire electrode surface oxidation, adopts the setting of cooling air sleeve pipe, reduce electrode rotor and A-frame temperature, extend electrode life with this.But to the mode that wire electrode adopts total travel insulation to surround, add equipment difficulty of processing and manufacturing cost, and the elongated porcelain tube that insulation is surrounded is very easily damaged.
The patent of invention of publication number CN2075302U discloses a kind of auto-ignition jetgun for heater of gas radiation pipe, comprise the cap that has manual firing hole and fire defector hole, cap wall there is an air hose, a thin plate pine is had to become the small combustion chamber of tubular in cap, one little fire-fighting mouth and spark point combination are stretched in little fiery combustion chamber through cap, little fire-fighting mouth is connected with a little fiery arm, and at cap, there are a mutually isolated bilayer sleeve lance tube assembly in central authorities, and outer tube is igniting primer.Igniting thermic load is the 5-10% of radiant tube heater thermic load.The patent of invention of publication number CN1570473A and the utility model patent of patent No. ZL200520043019.0 disclose a kind of gas remote ignition method and device, by igniter to be arranged on and interval, burner outlet place is greater than the place of one meter of distance, coal gas and a certain proportion of igniting air is passed in igniter, after high-voltage spark point combust mixed gas, utilize the operation of mist that kindling material is sent to burner outlet at a distance along passage and light mixed gas.Above patent all belongs to cold junction sparking mode, by being moved forward by traditional ignition location, improving the condition of work of ignitor, reducing the operating temperature of electricity fire igniting, extending electrode life thus.But there is the not high weak point of igniting reliability in the method, when air velocity is too fast, very easily make the flame core quenching of lighting, air turbulence degree is larger, affects larger.Also there is the security hidden troubles such as tempering in the method.
The utility model patent of publication number CN86204051U discloses a kind of gas fired radiant tubes with improvement ignition structure, ignitor device is fixed on air sparger, and the top of electrode needle curves certain angle, facing to the madial wall of air sparger, ensure more igniting selected element, improve igniting reliability.There is the not high weak point of igniting reliability in the method.
Therefore, we are in the urgent need to a kind of new burning torch, to solve the low problem of existing ignition success rate, ensure carrying out smoothly of production.
