Abstract
The utility model provides an injection type micropore burner, comprising a spray nozzle fixing frame, a suction collapsible tube, a mixing tube, a diffuser, a spray nozzle rear cavity and a burner head which are sequentially connected. A spray nozzle joint, a spray nozzle adjusting frame, a support nut and a spray nozzle are fixed on the spray nozzle fixing frame, a turbulent screen is disposed between the spray nozzle rear cavity and the burner head, and a plurality of micropores are uniformly distributed on the burner head. The injection type micropore burner has the following technical advantages that 1, the micropores can form a uniform burning surface conveniently, thereby increasing heat flow strength of unit area, air and gas can be sufficiently mixed by turbulent holes, tempering can be prevented when flame propagation speed is higher than air flow speed, flame stabilizing work range can be expanded, and 2, gas mixed passages of a gas spraying portion and a mixing portion are movably connected by the spray nozzle, thereby bringing convenience for installation and detachment and realizing easy cleaning and maintenance.
Description
Technical field
The utility model relates to a kind of injection type micropore burner that is used on gas combustion steaming cabinet, the steam stove, belongs to commercial technical field of burner.
Background technology
The gas burner of commercial stove use at present mainly is divided into blowing-type and injection type two classes.Air blast burner needs the air blast forced air supply combustion-supporting, and not only noise is big, need have electric power to use simultaneously.Simultaneously when excessive air coefficient is bigger than normal, is prone to from flame or takes off fiery phenomenon; And excess air coefficient is when less than normal, and the insufficient CO of causing discharge capacity of then will burning raises.And injection burner need not electrification, and the CO discharge capacity is low in the combustion thermal efficiency height, flame stabilization, flue gas.
But existing injection burner exists following weak point: combustion gas and air can not mix fully, and it is complete inadequately to burn.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of new injection type micropore burner is provided.
Injection type micropore burner of the present utility model, comprise the nozzle fixed mount, air-breathing collapsible tube, mixing tube, diffuser pipe, nozzle back cavity and the burner head that link to each other successively, wherein be fixed with nozzle connection, nozzle adjustment rack, support nut and nozzle on the nozzle fixed mount, it is characterized in that: be provided with turbulent net between nozzle back cavity and the burner head, be evenly distributed with a plurality of micropores on the burner head.Just can adjust the distance of nozzle by the screw of regulating on the cut-out governing frame apart from air-breathing collapsible tube.
Preferably,
The mesh area of said turbulent flow net is 1mm * 1mm, is that the stainless steel iron wire braiding of 1mm forms by diameter.
Said micropore area is 1.5mm * 3mm, is that the stainless-steel sheet of 1.5mm intersects in length and breadth and forms by thickness.
The utlity model has following technique effect:
1, in the utility model, micropore is convenient to form a uniform combustion front, and then improves the heat flow intensity of unit are.The turbulent flow hole makes air fully mix with combustion gas, and can prevent that when flame propagation velocity is higher than air velocity tempering from taking place, and enlarged the flame stabilization working range.Combustion gas can be strengthened and Air mixing after directly spraying into conical hybrid channel by nozzle, and the balance of maintenance fuel gas supply and consumption, after gaseous mixture enters the combustion chamber, finish the balance of air velocity and burning velocity, thereby reach sufficient combustion, stable purpose;
2, jet of the present utility model is adopted nozzle to flexibly connect with the mixed gas passage that mixes portion, thereby convenient mounting or dismounting, clears up easily and keeps in repair.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the Facad structure schematic diagram of injection type micropore burner of the present utility model;
Fig. 2 is that the A of burner head of injection type micropore burner of the present utility model is to view.
Wherein 1 is nozzle connection, and 2 is the nozzle fixed mount, and 3 is the nozzle adjustment rack, and 4 is the support nut, and 5 is nozzle, and 6 is air-breathing collapsible tube, and 7 is mixing tube, and 8 is diffuser pipe, and 9 is the nozzle back cavity, and 10 is burner head, and 10-1 is turbulent net, and 10-2 is a micropore.
Specific implementation method
As shown in Figure 1, 2, injection type micropore burner of the present utility model, comprise the nozzle fixed mount 2, air-breathing collapsible tube 6, mixing tube 7, diffuser pipe 8, nozzle back cavity 9 and the burner head 10 that link to each other successively, wherein be fixed with nozzle connection 1, nozzle adjustment rack 3, support nut 4 and nozzle 5 on the nozzle fixed mount 2, wherein, be provided with turbulent flow net 10-1 between nozzle back cavity 9 and the burner head 10, be evenly distributed with a plurality of micropore 10-2 on the burner head 10.Just can adjust the distance of nozzle by the screw of regulating on the cut-out governing frame apart from air-breathing collapsible tube.The mesh area of turbulent flow net is 1mm * 1mm, is that the stainless steel iron wire braiding of 1mm forms by diameter.The micropore area is 1.5mm * 3mm, is that the stainless-steel sheet of 1.5mm intersects in length and breadth and forms by thickness.What this burner head adopted is the bar shaped fire hole.
The course of work of the present utility model is as follows: combustion gas is under certain pressure, spray from nozzle 5 with certain flow rate, enter air-breathing collapsible tube 6, combustion gas simultaneously sucks primary air by the energy of itself, combustion gas and primary air mix in mixing tube 7, pressure further improves after burner head flows out behind diffuser pipe 8 then, burns.Wherein nozzle 5 is not only carried desired combustion gas, also relies on the certain air of ejector action injection simultaneously.Drag losses when air-breathing collapsible tube 6 act as and reduces air and enter.Mixing tube 7 fully mixed combustion gas-air mixture before entering diffuser pipe.Diffuser pipe 8 further mixes combustion gas and air when further improving the pressure of gases.The effect of burner head 10 is that combustion gas-air mixture is distributed on each fire hole equably, and go forward side by side line stabilization and burning completely require the pressure of each point mist to equate for this reason, requires the auxiliary air can be unimpeded equably to each fire hole.
