Description

A kind of very hot oven combustion gas flame gun

One, technical field

It is a kind of very hot oven combustion gas flame gun of the energy that the utility model relates to natural gas, oil liquefied gas, coal gas, biogas, can be used for firing stove, boiler etc., also can be used as the spray gun on the gas kitchen ranges.

Two, background technology

At present, with the natural wind is too much, the problems such as burning is insufficient, energy waste, environmental pollution of the flourishing seedling of gas gun ubiquity of combustion system, and have the problem that mixing is inhomogeneous, burning is insufficient, heat energy runs off in a large number, energy waste is serious equally with the gas gun of forcing the wind combustion system, therefore, the improvement of flame gun is imperative.

Three, utility model content

At above-mentioned situation, the purpose of the utility model just provides new a kind of very hot oven combustion gas flame gun, it is insufficient effectively to overcome burning, the problem that contaminated environment and energy run off, the technical scheme of its solution is, inlet loudspeaker top is equipped with the outlet loudspeaker through neck and is constituted the flame gun body, pass neck and be equipped with ignitor in first nozzle center, pass the rifle body and on first nozzle, ground wire is housed, the combustion jet chamber is formed by first nozzle and the second outside nozzle of inside in flame gun body top, flame gun body bottom is fixed together through nut by the gas nozzle of inside and air door thereof and outside pedestal and constitutes the air inlet air-intake device, mother's with lock gas inlet pipe is equipped with in its underpart, the utility model novel structure uniqueness, easy to use, safety, sufficient combustion, quick heating, energy savings, non-environmental-pollution, wide application, economic and social benefit is huge.

Four, description of drawings

Accompanying drawing is structural front view of the present utility model (upper and lower have partly cut-away).

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Provide by accompanying drawing, the utility model is, inlet loudspeaker 1 top is equipped with outlet loudspeaker 3 through neck 2 and is constituted the flame gun body, pass neck 2 and be equipped with ignitor 13 at first nozzle, 4 centers of inside, pass the flame gun body and on first nozzle, ground wire is housed, constitute ignition circuit with ignitor, the combustion jet chamber is formed by first nozzle 4 and the second outside nozzle 5 of inside in flame gun body top, flame gun body bottom is fixed together through nut 11 by the gas nozzle 6 of inside and air door 9 thereof and outside pedestal 10 and constitutes the air inlet air-intake device, and female 7 gas inlet pipe 8 with lock is equipped with in its underpart.

In order to guarantee result of use, the round long tube that gas inlet pipe 8 becomes for copper, the porous rounded body that first nozzle 4 and second nozzle 5 are made for extreme temperature refractory, the refractory ring of formation porous between the two; Gas nozzle 6 stretches in the spray gun inlet loudspeaker 1, is regulated by gas nozzle nut 11, and air door 9 is rotary air door, and intake is regulated by rotary air door 9; Spray gun inlet loudspeaker 1, spray gun outlet loudspeaker 3 and spray gun neck 2 are the circular cone hollow body.Ignitor 13 is used to import high pressure and lights a fire.

The utility model makes full use of the high temperature of spray tip itself, to oxygen in combustion gas and the air heat up, pressurize, quicken, cut apart, collision, infrared radiation etc., make it reach good mixing, fully burning, therefore, both just (full scale 0.1mpa under the very low condition of gaseous-pressure, the gauge measurement value is 0-0.001mpa) tangible jet power also arranged, bluish violet flame (oil liquefied gas) or light blue flame (natural gas) are in the majority in the flame, reddish yellow flame almost be cannot see, combustion gas is able to abundant burning, has saved the energy, has reduced the pollution to environment.

In good characteristic of the present utility model and the present application in practice of its scientific and reasonable structure, its working condition is, the combustion gas of spray gun enters gas nozzle 6 by gas inlet pipe 8 through combustion gas copper pipe locknut 7, spray gun inlet loudspeaker 1 are injected in combustion gas, gas nozzle is screwed into approach screw and is fixed on enter the mouth nut 11 on the gas nozzle seat 10 of 1 loudspeaker lower edge of spray gun, nut 11 on the rotatable gas nozzle carrier 10 can change the degree of depth that gas nozzle 6 enters spray gun inlet loudspeaker 1, bring the wind speed of spray gun inlet loudspeaker 1 into adjusting, the nut at air door 9 centers also is screwed on the gas nozzle 6, distance between rotary air valve 9 adjustable damper 9 and the spray gun inlet loudspeaker 1, be convenient to control intake, combustion gas copper pipe locknut 7 is used to pin gas nozzle 6 and combustion gas input copper pipe 8, prevent gas leakage, inject the combustion gas of spray gun inlet loudspeaker 1, along with arriving first nozzle, 4 gaseous mixtures through spray gun neck 2, the air of bringing into carries out the mixed combustion first time at this, burning gases enter second nozzle 5 again and carry out the mixed combustion second time with air, and clean-burning high-temperature gas band sound of the wind and sprayed second nozzle.With ground wire 12 ground connection, light a fire by ignitor 13 input high pressure, safety, effective.

The utility model has following characteristics:

At first be that secondary mixed combustion, twice mixed combustion all consist of between first and second nozzle of top The refractory ring of porous carries out in (combustion chamber), and the contact area that porous makes oxygen in combustion gas and the air greatly Increase, simultaneously, because the nozzle of conical structure center temperature when burning is very high and produce very strong Infrared ray, high temperature to around the width of cloth penetrate, make gas expansion, pressure increases, density reduces, proportion descends, Produce lift, act on expanding gas on the spray gun output loudspeaker 3 inwall inclined-planes in the promotion of reaction force The lower second lift that produced again, two kinds of lift stacks make flame acceleration spray to outlet, because nozzle γ-ray emission pressure accelerates upwards to spray, and surrounding air is divided into by the aperture on the nozzle ring to be permitted Multiply is replenished to the center, carries out fierce collision with the center high-temperature gas, makes oxygen and combustion in the air Gas reaches abundant mixing;

Second characteristic is, the air inlet wind speed is fast, because outlet flame injection wind speed is fast, brings the import intake big, wind speed is fast, be equivalent to add a little blower fan, therefore, it can not subtract by intake under the very low condition of gaseous-pressure, combustion gas is fully mixed with enough air, solved the burner that relies on natural wind, when gaseous-pressure is not enough, the more inadequate problem of burning;

The 3rd characteristics are that the spray tip of this burner adopts extreme temperature refractory to make, and at high temperature can produce infrared radiation, good heat conductivity, flame temperature height, quick heating;

The 4th characteristics are that ignitor 13 input high pressure are lighted a fire.

From the above, the utlity model has good characteristics such as quick heating, energy-saving and environmental protection, wide application, economic and social benefit is huge.
