Description

A kind of Laser Igniter and application method

Technical field

The invention belongs to boiler, automobile, Industrial Stoves, household gas burning range, soot blower fields, swash more particularly, to one kind Luminous point firearm.

Background technique

Boiler, automobile, Industrial Stoves, household gas range, gas heater, soot blower field use in existing technology Be the mode lighted a fire of electrion electric spark to light a fire, this device is by power circuit by boosting, so Igniting is realized using the electric spark that electric interpolar discharge is formed afterwards, it is lack of standardization when operating, it is held beyond electric discharge section current density Too small between arteries and veins by ability, chip removal is bad etc. will also result in carbon distribution between electrode under carbon distribution or use environment between electrode, between electrode Electric pole short circuit can will not be generated electric spark by carbon distribution, cause loss of ignition.

Summary of the invention

The Laser Igniter that the problem to be solved in the present invention is to provide a kind of structures to be simple and convenient to operate, work efficiency is high.

In order to achieve the above objectives, the technical scheme of the present invention is realized as follows: a kind of Laser Igniter, including multiple swash Optical assembly, the laser module are located in fixing piece, and the laser module is parallel to one end transmitting far from the fixing piece Light beam, the light beam that multiple laser modules issue is pooling a focus at the 10~30mm of fixing piece, described The power of laser module is 100 to 150mW.

Further, the outer dimension of the fixing piece is consistent with spark plug shape with electrion.

Further, the light beam that multiple laser modules issue is pooling a coke at the fixing piece 20mm Point.

Further, the quantity of the laser module is three, the axis of the relatively described fixing piece of three laser modules Line is uniformly arranged.

Further, the center line of each laser module and the central axes of the fixing piece are formed by acute angle It is 30~60 degree.

Further, the laser module is battery powered.

Further, the laser module is by alternating current switch constant-current source.

Further, the alternating current of 220V or 380V can be converted into the straight of 4~8VDC by the alternating current switch constant-current source Galvanic electricity.

Further, by constant current source power supply after multiple laser module series connection.

Use a kind of method of Laser Igniter:

Laser Igniter is mounted on mixing point firearm by the first step；

Second step opens air valve, introduces compressed air into system and purge to equipment inside；

Third step is opened air valve and acetylene valve, is controlled flow, blending concentration suitably can exploding gas；

4th step closes air and acetylene solenoid valve, gives laser ignition after delay 0.5 second when gas is full of Impulsive tank Device send ignition signal, and laser module issues the combustion gas that laser beam lights explosive gas；

5th step；It may wait for signal after explosion to continue igniting next time or stop working.

Compared with prior art, the advantages and positive effects of the present invention are: the 1, present invention is replaced using laser motor The high voltage arc of script, and the low-power laser component for arriving 150mW using 100, the laser beam of generation are gathered together to be formed Biggish energy point, to light combustion gas, igniting precision is high, and duration of ignition controllable precise improves ignition quality；2, because eliminating height Pressure ring border will not generate interference to the electric signal of on-site data gathering without examining the problems such as filtering high-voltage isulation；Even if 3, endangering It will not be highly-safe as generating danger because of high voltage arc in dangerous environment；4, between carbon distribution will not being generated and causing ignitor Short circuit.5, its shape is identical with spark plug, and replacement is convenient；6, circuit is simple, it is only necessary to the Constant Electric Current of tens mA Source powers for laser module.
