Abstract
The utility model provides an even flame jet type burner, which comprises an annular flame spreading disc. A plurality of gas nozzles are arranged on the flame spreading disc, a gas inlet guide pipe is respectively sleeved on each gas nozzle, a plurality of air aspirating holes are arranged on the pipe wall of the gas inlet guide pipe, an outer sleeve is connected at the upper part of the gas inlet guide pipe, the upper end of the gas inlet guide pipe is penetrated through the bottom part of the outer sleeve and extended into the outer sleeve, a plurality of secondary air aspirating holes are arranged on the side wall of the outer sleeve on the periphery of the gas inlet guide pipe, and a plurality of flame jetting holes are arranged at the upper end of the outer sleeve. The utility model has the advantages that the structure is simple, the gas can be burnt fully, the flame power is more dispersed and evener, the flame jetting holes are not easy to be blocked up, etc., and the utility model is used for the burning of pipeline gas and low pressure liquid gas.
Description
Technical field
The utility model relates to a kind of combustion gas tool, refers in particular to the burner that is used for low pressure pipeline gas and liquefied gas burning.
Background technology
Low-pressure gas or pipe natural gas are a little less than the low firepower of pressure; For improving its firepower, traditional way is directly tracheae to be connected with dividing the fire dish, and on minute fire dish, a plurality of gas nozzles are set, on nozzle, put the air mixing tube, and a plurality of air admission holes are set on the air mixing tube, gas-flow muscle power by the gas nozzle ejection is brought the mixed once combustion air synchronously into, by the fire output hole ignition combustion that is arranged on air mixing tube upper end.There is following deficiency in this structure: only by mixed once, the lack of air of importing causes combustion gas fully to burn (1); (2) flame of fire output hole is comparatively concentrated, and is even inadequately to the heating in the bottom of a pan; (3) because fire output hole is bigger, easily fall into foreign matter, phenomenon results in blockage.
The utility model content
The utility model is at the deficiencies in the prior art, provides a kind of flame even injecting combustor, reaches that combustion gas can fully be burnt, pan homogeneous heating, the not susceptible to plugging purpose of fire output hole.
The purpose of this utility model is achieved in that the even injecting combustor of a kind of flame, comprise annular branch fire dish, on minute fire dish, be provided with a plurality of gas nozzles, on each gas nozzle, be with air induction conduit respectively, on the tube wall of air induction conduit, be provided with a plurality of primary air suction holes, described air induction conduit top is connected with outer sleeve, the upper end of air induction conduit is passed the outer sleeve bottom and is extended in the outer sleeve, outer sleeve sidewall in the air induction conduit periphery is provided with a plurality of auxiliary air suction holes, is provided with a plurality of fire jetting holes in the upper end of outer sleeve.
Described fire jetting hole comprises central fire jetting hole and a plurality of central fire jetting hole secondary fire jetting hole on every side that is evenly distributed on, the outside of described secondary fire jetting hole opening deflection gas nozzle.
After the utility model adopts said structure, by connecting outer sleeve on air induction conduit top, and on the outer sleeve sidewall of air induction conduit periphery, the auxiliary air suction hole is set, twice inhaled air can with fully the mixing of combustion gas, guarantee the completing combustion of combustion gas, firepower is powerful; The structure in the outside of the structure of many fire holes and secondary fire jetting hole opening deflection gas nozzle can make firepower disperse more and be even; Fire jetting hole can prevent that falling into foreign matter results in blockage.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is the vertical view of Fig. 1;
The specific embodiment
Consult illustrated in figures 1 and 2, the even injecting combustor of a kind of flame of the present utility model, comprise annular branch fire dish 1, on minute fire dish 1, be provided with five gas nozzles 2, on each gas nozzle 2, be with air induction conduit 3 respectively, be evenly equipped with four primary air suction holes 31 on the tube wall of air induction conduit 3, the tube chamber of air induction conduit 3 forms primary air---combustion gas mixing passage; Be connected with outer sleeve 4 on air induction conduit 3 tops, the upper end of air induction conduit 3 is passed outer sleeve 4 bottoms and is extended in the overcoat letter 4, outer sleeve 4 sidewalls in air induction conduit 3 peripheries are evenly equipped with four auxiliary air suction holes 41, make the outer sleeve 4 interior air that form---the secondary mixing of combustion gas, the gasification tunnels of top, air induction conduit 3 ends, the assurance air fully mixes with combustion gas; Offer a plurality of fire jetting holes at the top of outer sleeve 4, described fire jetting hole comprises a central fire jetting hole 42a and a plurality of secondary fire jetting hole 42b, secondary fire jetting hole 42b is evenly distributed on around the central fire jetting hole 42a, secondary fire jetting hole 42b opening slightly is partial to the outside of gas nozzle 2, so that burning fire power is disperseed more with even.
When the utility model specifically uses, the gas inlet pipe road enters the inner chamber of branch fire dish 1, by entering air induction conduit 3 after gas nozzle 2 ejections, the fluid force of combustion gas drives air four primary air suction holes 31 from the tube wall of air induction conduit 3 and sucks, realize primary air---combustion gas mixing synchronously, gasification, gaseous mixture enters outer sleeve 4 middle parts then, the fluid force of gaseous mixture drives air and sucks from four the auxiliary air suction holes 41 on outer sleeve 4 sidewalls, realize air---the secondary of combustion gas mixes, gasification is carried out the injecting type burning on outer sleeve 4 tops by central fire jetting hole 42a and a plurality of secondary fire jetting hole 42b then.
Claims (2)
