Description
Technical field
The present invention relates to igniting gas gun, be specifically related to a kind of structure-improved of the gas gun of lighting a fire.
Background technology
Existing igniting comprises the spark lever being connected with high-field electrode with gas gun, fuel gas (device in Gas) conveyance conduit and be arranged at the fuel gas nozzle of the port of export of fuel gas conveyance conduit, and at fuel gas nozzle, place is provided with inlet scoop.Its ignition principle is: when fuel gas is sprayed by nozzle, under the induced effect of air-flow, can form certain negative pressure at inlet scoop place, thereby by air intake near nozzle, mix with fuel gas; High-field electrode electric discharge the electric spark producing by spark lever, and the mist of fuel gas and air is lighted.Because it does not effectively improve the structure of burner, increase the mixed effect of fuel gas and air, and just utilized near the characteristic that has low pressure fluid, so cause ignition success rate low.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the present invention is to provide a kind of ignition success rate high, and generate the structure-improved of the igniting gas gun of flame stabilization.
The present invention solves the technical scheme that its technical problem takes: a kind of structure-improved of the gas gun of lighting a fire, comprise fuel gas carrier pipe, spark lever, be arranged on the fuel gas nozzle of the port of export of described fuel-supply pipe, and be arranged near inlet scoop fuel gas nozzle, it is characterized in that: also comprise one end sealing, the protective casing of an end opening; Described fuel gas carrier pipe, spark lever and fuel gas nozzle are all axially disposed within the tube chamber of described protective casing, and the end face of the relatively described spark lever of openend end face of described protective casing has certain overhang; On the tube wall of described protective casing, be provided with multiple air inlets that communicate with its inner chamber; At the front end of described fuel gas nozzle, the gradually premixer of opening form is set.
As to further improvement of the present invention, make to be arranged on air inlet on described protective casing tube wall and be elongated and with the rectangle air port of wind scooper.
As to further improvement of the present invention, the tube chamber of the relatively described fuel gas carrier pipe in jet chamber of described fuel gas nozzle is reducing form.
As to further improvement of the present invention, the end of described fuel gas nozzle is provided with circular arc concave surface, and described circular arc concave surface place arranges spout hole, and the corresponding described inlet scoop of recess that forms of described circular arc concave surface.
As to further improvement of the present invention, the head of described fuel gas nozzle and premixer's part adopt the steel material of heat-and corrosion-resistant to make.
The invention has the beneficial effects as follows: the defect such as it has solved, and ignition success rate is low, fault rate is higher, maintenance cost is higher, poor reliability, service life are short.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the local structure for amplifying schematic diagram at A place in Fig. 1;
In figure: 1 fuel gas carrier pipe, 2 spark levers, 3 protective casings, 31 air inlets, 4 inlet scoops, 5 premixers, 6 fuel gas nozzles, 61 circular arc concave surfaces.
The specific embodiment
For the ease of understanding technology contents of the present invention, below in conjunction with accompanying drawing, technical scheme of the present invention is described further.
As depicted in figs. 1 and 2; a kind of structure-improved of the gas gun of lighting a fire; comprise fuel gas carrier pipe 1, spark lever 2, be arranged on the port of export of described fuel-supply pipe 1 fuel gas nozzle 6, be arranged on inlet scoop 4 and one end sealing near fuel gas nozzle 6, the protective casing 3 of an end opening.Described fuel gas carrier pipe 1, spark lever 2 are axially stretched in the tube chamber of described protective casing 3 by the lower end of described protective casing 3 after, by the lower end closed of described protective casing 3.Because described fuel gas nozzle 6 is axially disposed within the upper end of described fuel gas carrier pipe 1; so fuel gas nozzle 6 is also positioned at the tube chamber of described protective casing 3, and the end face of the relatively described spark lever 2 of openend end face of described protective casing 3 has certain overhang.The position of described spark lever 2 relative inlet scoops 4 can, with reference to prior art, repeat no more herein.On the tube wall of described protective casing 3, be provided with multiple air inlets 31 that communicate with its inner chamber.Adopt this kind of structure, can guarantee that the flame that extraneous wind speed generates at 70m/s situation down-firing can not be blown out, and each parts are placed in protection sleeve, can greatly reduce damage fault, reduce maintenance cost, increase the reliability using high.
Preferably make to be arranged on air inlet on described protective casing 3 tube walls 31 for elongated and with the rectangle air port of wind scooper, can increase like this wind effect, and avoid the air stream of external environment condition that its wind effect is produced and interfered.The concrete conditions such as position, number and the shape size of the air inlet 31 having on protective casing 3, combustion characteristics that can based on fuel gas, is guaranteeing to have under the prerequisite of enough intakes, specifically arranges.
At the front end of described fuel gas nozzle 6, the gradually premixer 5 of opening form is set, as inverted taper or trumpet type, there is certain retraction amount the upper surface of the relative protective casing 3 in the upper end of premixer 5.Making the tube chamber of the relatively described fuel gas carrier pipe 1 in jet chamber of described fuel gas nozzle 6 is reducing form, can increase like this speed that fuel gas is sprayed by described fuel gas nozzle 6, thereby flowing of the gas of drive fuel gas Around Jet, further improves the premixing effect of fuel gas and air.Meanwhile, can circular arc concave surface 61 be set in the end of described fuel gas nozzle 6, described circular arc concave surface 61 places arrange spout hole, and the corresponding described inlet scoop 4 of the recess that forms of described circular arc concave surface 61.After being sprayed by spout hole, fuel gas can form mixed flow to a certain degree, and the recess that circular arc concave surface 61 forms provides enough flowing spaces for this mixed flow, thereby form eddy flow to a certain degree, the mixability of the air that further increases fuel gas and enter from inlet scoop 4, guarantees the success rate of lighting.By spark lever 2, by high-field electrode, sparking is lighted, and the indent that first can form at circular arc concave surface 61 forms flammule, flammule moves ahead, light by the fuel gas air-flow of the flared section of premixer 5, make flame ejection, finally not only safety but also completed reliably ignition process.
The head of described fuel gas nozzle 6 and premixer's 5 parts adopt the steel material of heat-and corrosion-resistant to make, and guarantee the present invention's serviceability at high temperature, increase the service life.
Fuel gas can adopt the one of the inflammable gases such as coal gas, liquefied petroleum gas, natural gas.
This igniting gas gun ignition process, by the flammule main flame that ignites, can improve ignition success rate greatly.The defect such as it has solved that ignition success rate is low, fault rate is higher, maintenance cost is higher, poor reliability, service life are short.
Above technical characterictic has formed preferred forms of the present invention, and it has stronger adaptability and executes effect, can increase and decrease as required non-essential technical characterictic, meets the different actual conditions in actual use.But protection scope of the present invention is not limited to above-mentioned concrete scheme, its protection domain is finally subject to the restriction of claims of the present invention.In the situation that not deviating from design philosophy of the present invention, for a person skilled in the art, can make multiple conversion or be equal to replacement the present invention in conjunction with common practise or prior art, it all should fall within the scope of protection of the present invention.
