Abstract
The invention relates to a fuel gas stove, in particular to a vertical injection device of a direct injection type combustor. The vertical injection device provided by the invention comprises an air mixing pipe which is vertically arranged below a fuel gas seat and a burner cap; the lower part of the air mixing pie is of a horn; an adjustable air door is arranged at the bottom surface of a horn opening of the air mixing pipe; and at least three spray nozzles are arranged at the bottom of the air mixing pipe and are connected with a gas piping. According to the vertical injection device, the spray nozzles for injection in multiple locations are arranged at the bottom of the air mixing pipe, and an overall design of the direct injection type combustor is combined, so that after fuel gas enters the air mixing pipe through a plurality of nozzles, the fuel gas injected by the nozzles are fully mixed with nearby air and then flows into a main air passage for being supplied to the combustor. The vertical injection device has the effects that the heat efficiency is improved greatly, and the discharge capacity of carbon oxide is reduced effectively, so that energy conservation and environmental protection are realized.
Description
Technical field
The present invention relates to a kind of gas kitchen ranges, particularly a kind of vertical injection apparatus of direct injection combustion device.
Background technology
Along with the popularization of worldwide energy scarcity and energy-conserving and environment-protective, how the gas kitchen ranges that all relates to as huge numbers of families has become problem that insider generally be concerned about and urgently will solve to reach to energy-conservation maximization through technological innovation, and the patent of invention of inventor initiative number is 200520061338.4; Denomination of invention is a kind of balanced burner that has, and adopts the structure of direct jet supply gas, has broken the deficiency of the unbalanced and combustion gas of traditional horizontal air feed gas supply and the mixed ratio of air; Utilize the relation that temperature is directly proportional with air velocity in the pneumatology, air velocity is accelerated, thereby reach refinement through the high speed wearing and tearing of micel in the combustion gas; Consequently significantly improved the efficient of burning; Practiced thrift combustion gas, in continuous use, we also find; Traditional jet single nozzle that adopts has attraction function to the air near nozzle; But then not obvious to its effect of air far away, and the mixed of air and combustion gas directly has influence on the discharge capacity of the thermal efficiency and the carbon monoxide of burning than quality, therefore; Design the rational jet mixed structure that more becomes, could realize better energy-saving effect.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of speed of fuel gas injection faster, with more the become vertical injection apparatus of rational direct injection combustion device of Air mixing.
Technical scheme of the present invention is: a kind of vertical injection apparatus of direct injection combustion device; Comprise the mixing wind tube of vertical means in burned gas base, fire lid below; Said mixing wind tube bottom is loudspeaker structure; In the bell-mouthed bottom surface of mixing wind tube adjustable air door is housed, in the bottom of mixing wind tube at least 3 nozzles is housed, said each nozzle is connected with air delivering pipeline.
Further: above-mentioned nozzle is 3, comprising a center nozzle and be the nozzle that symmetry is laid in the center nozzle.
Further: above-mentioned nozzle is 4, comprising a center nozzle and be the nozzle of Chinese character pin-shaped laying.
The present invention is owing to adopted the nozzle that multi-point injection is set in the mixing wind tube bottom; In conjunction with the master-plan of direct injection combustion device, after combustion gas gets into mixing wind tubes by some nozzles, the combustion gas that its each nozzle sprayed respectively with its near air fully mix; Import main airway and supplied burner then; Its effect is when can significantly improving the thermal efficiency, reduces the discharge capacity of carbon monoxide effectively, reaches the purpose of not only energy-conservation but also environmental protection.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Fig. 1 is a general illustration of the present invention.
Fig. 2 is the sketch map of 3 nozzles for the present invention.
Fig. 3 is the sketch map of 4 nozzles for the present invention.
The specific embodiment
The present invention such as Fig. 1, Fig. 2, shown in Figure 3; A kind of vertical injection apparatus of direct injection combustion device; Comprise the mixing wind tube 3 of vertical means in burned gas base 1, fire lid 2 belows, said mixing wind tube 3 bottoms are loudspeaker structure, in mixing wind tube 3 bell-mouthed bottom surfaces adjustable air door 4 are housed; In the bottom of mixing wind tube 3 at least 3 nozzles 5 are housed, said each nozzle 5 is connected with air delivering pipeline.
Above-mentioned nozzle 5 is 3, comprising a center nozzle 51 and be the nozzle 52 that symmetry is laid in center nozzle 51.
Above-mentioned nozzle 5 is 4, comprising a center nozzle 51 and be the nozzle 52 of Chinese character pin-shaped laying.
In addition, more smooth and easy for making fuel gas injection, the above-mentioned bell-mouthed angle of fuel gas injection direction and mixing wind tube 3 bottoms that is laid near the nozzle 52 the center nozzle 51 is close.
Need to prove that what the present invention was suitable for is the direct injection combustion device, no matter the burned gas base of burner, fire lid adopt which kind of structure and fire lid flame burning form, as long as adopted the structure of many nozzles all should be regarded as falling into protection scope of the present invention.
