Separate type burner assembly 2 further include be set in burner body 21 it is right with the air nozzle 12 that divides in gas pedestal 1 The independence for directing gas flow direction for answering circumference to be arranged mixes conductance flowing plate 4, further includes the Multi-hole infrared ray combustion being sequentially placed Burn plate 5, exterior decorative circle 6, interior trim fire-protection ring 7 and central burner 8.1 upper edge of gas pedestal is divided to burn along setting stationary positioned The positioning port of device ontology 21 and the installation position of fixed ignition needle and inductive needle, make burner body 21, fixed ignition needle and induction Needle can be relative to dividing 1 independent disassembling of gas pedestal and installation.Injection divides gas manifold 3 to be arranged vertically upward or angled with air nozzle 12 Setting, with air nozzle 12 in contacting or contactless be correspondingly arranged.Independent mixed conductance flowing plate 4 includes lateral deflector 41, longitudinal direction Deflector 42 and located lateral plate 43, located lateral plate 41 make independent mixed conductance flowing plate 4 be fixed on 12 side of air nozzle, longitudinally lead Flowing plate 42 is connect with located lateral plate 43, and tilts upward covering air nozzle 12, and lateral deflector 41 connects longitudinal deflector 42 Upper end, whole " it " set up of character patt ern change the direction of motion for guiding gas and recycle around the mixed air cavity of cylindrical inner body Movement.
Injection divides gas manifold 3 to include the bottom being connected to air nozzle 12 and the air ejection portion above bottom, bottom Upper outlet be arranged to bell shape, air ejection portion includes ejection cavity and shell, and even circumferential setting air draws on shell Perforation.Burner body 21 can be integrally formed using forging type, can also be using the bottom part for dividing gas manifold with injection Riveted or both modes such as grafting, threaded connection of coincideing naturally are real after the mixed air cavity punching press of punch forming and side, roll forming Existing flexible processing, it is therefore an objective to realize scale, it is cost effective.
The working process of this embodiment is as follows:
Combustion gas required for separate type burner assembly 2 is by dividing gas pedestal 1 by air inlet pipe arrival after ontrol valve assembly Inside is realized after control distribution and is sprayed in center air nozzle 121, middle ring air nozzle 122, outer ring air nozzle 123, drives Air enters corresponding injection and divides gas manifold 3.Center air nozzle 121 spray combustion gas after center injection divides gas manifold, into Enter central burner, under the action of lighting a fire needle-discharging, realizes that central flame is lighted, thus the middle ring outer ring fire that ignites.In lighting Internal heat carries out heating to security personnel's total system inductive needle is put out to which order to security system works normally.Traditional infrared gas jamb Only one or two ejector pipes, therefore in order to keep enough air introduction volumes, it is necessary to divide gas manifold 3 to increase injection and adds The long entrance for being just able to maintain auxiliary air is enough, but the injection increased after lengthening divides gas manifold 3 in same stream pressure In the case of, flow velocity can slow down spray distance and can shorten, (principle refer to use flexible rubber hose waterproof, bore is bigger, the flow velocity of water it is slower away from From closer, if bore reduced, water flow becomes effectively to penetrate immediately remoter), it is based on this principle, the present embodiment is improved to a plurality of Air nozzle 12 and reduction injection divide 3 bore of gas manifold to combine, and allow more injections that gas manifold 3 is divided to force injection fed oxygen from air, real It now only needs shorter injection stroke to can be achieved with oxygen required for entire burner full combustion, and keeps burner volume It is smaller.
The combustion gas of middle ring outer ring drives air under the action of injection principle after the ejection of each air nozzle 12 of excessive gas pedestal 1 Divide gas manifold 3 bottom ejecting port into injection, divides in gas manifold 3 that twist ascending motion is tentatively mixed in injection, When rising to injection and divide the diffusion horn mouth position on 3 top of gas manifold, there is diffusion and accelerate (megaphone amplification principle) Reach independent mixed gas air deflector.Due to dividing the structure of gas manifold 3 using more than 12 injections of more air nozzles, combustion gas is entering burning Device ontology 21 has multi beam combustion gas after mixing air cavity, must the air combustion directly through Multi-hole infrared ray burner plate 5 if do not guided Gas is not thoroughly mixed and is just ignited, therefore burns and insufficient cause that the thermal efficiency is low and exhaust gas discharge is exceeded.It therefore must be each Injection divides the top of gas manifold 3 to increase a secondary ramp type deflector, and guiding gas changes the direction of motion around cylinder The mixed air cavity of inner body does shuttling movement, so that multiply combustion gas sufficiently premixed after multi-turn mixing, to pass through It is released in the form of infrared light-wave after the fully premixed burning of the aperture realization direct injection of Multi-hole infrared ray burner plate 5 a large amount of Heat.
Since each injection divides gas manifold 3, vertical injection, the short design of injection stroke, combustion gas mixing logistics speed are pressed fastly upwards Power is big, and the high-temperature region for having independent mixed conductance flowing plate 4 that Multi-hole infrared ray burner plate 5 is isolated, therefore it is excessive to have prevented oven former pressure With the disadvantage after infrared combustion plate rupture in the burning of jet mouth position.
Due to the structure of traditional direct spray type hurner nozzle upward, it is easy to appear liquid, the aperture that sundries passes through burner plate It falls into 12 hole of air nozzle and causes to stop up failure.After increasing independent mixed conductance flowing plate 4, independent mixed conductance flowing plate 4 is covered in Air nozzle and injection divide the top of gas manifold, have blocked the liquid and sundries fallen down, and sundries and a small amount of liquid can be deposited in solely At vertical mixed 4 slope of conductance flowing plate, big quantity of fluid can also divide along injection if entering 3 wall of gas manifold fall into 12 periphery of air nozzle and Air nozzle 12 will not be blocked, guarantees the smooth supply of combustion gas, realizes the maintenance-free feature of burner.
The split type infrared burner of the more ejector pipes of the direct-injection of the present embodiment, structure is simple, novel in design, processing technology letter Single, processing cost is low, while airpath design, the creative multistage independent diversion design optimized, changes the side of air-flow To and speed, in addition make air and combustion gas mixing uniform, burning sufficiently, improves the thermal efficiency and reduces the discharge of carbon monoxide.
Embodiment two
Air nozzle 12 in the present embodiment includes center air nozzle 121 and outer ring air nozzle 123, and injection divides gas manifold 3 to wrap It includes and is correspondingly arranged center injection with center air nozzle 121 and outer ring air nozzle 123 gas manifold and outer ring injection is divided to divide gas manifold, Its structure is as the split type infrared burner structure of the more ejector pipes of the direct-injection in embodiment one.
It should be noted that suitably increase and decrease air nozzle 12 and injection divide the quantity of gas manifold 3 that combustion gas and air can be made mixed Composition and division in a proportion example is more reasonable, various gas sources is adapted to, therefore increase air nozzle 12 and injection divide the behavior of 3 quantity of gas manifold, at this In the protection scope of invention, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all at this Within the spirit and principle of invention, any modification, equivalent replacement, improvement and so on should be included in protection model of the invention Within enclosing.
