Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.
Referring to figs. 1 through Fig. 3, a kind of air distribution disk 10, comprise fuel gas inlet 11, inner ring blast tube 12, outer shroud blast tube 13, combustion gas between inner ring blast tube 12 and outer shroud blast tube 13 in circle ring area divide gas storehouse 14 and air duct 15, combustion gas divides gas storehouse 14 to be communicated with outer shroud blast tube 13 and fuel gas inlet 11, the same prior art of effect of above-mentioned each parts, and combustion gas divides gas storehouse 14 and air duct 15 area occupied to be the area of whole circle ring area between inner ring blast tube 12 and outer shroud blast tube 13.Unlike the prior art, in the present embodiment, combustion gas divides gas storehouse 14 to be the fan-shaped storehouse extended out gradually from inside to outside, and its quantity is two and is oppositely arranged.
Combustion gas divides gas storehouse 14 for quantity two, and its quantity reduces compared to existing technology, then make air duct 15 area occupied relatively increase, the air capacity then introduced in fuel gas buring process increases, and then amount of oxygen increases, make burning more abundant, thorough, the flue gas of generation is few; Simultaneously, combustion gas divides gas storehouse 14 to be the fan-shaped storehouse expanded gradually from inside to outside, combustion gas is made to be that diffusion type outwards sprays, combustion gas and air are mixed further, improve the uniformity coefficient of combustion gas and air mixing, even if then combustion gas divides gas storehouse quantity to reduce the uniformity coefficient that also can not affect combustion gas and air mixing compared with prior art, combustion gas and air mix then can accelerated combustion, improves fuel gas buring efficiency.
Further, owing to will enter in outer shroud blast tube 13 after combustion gas and air mixing, external ring fire cover above air distribution disk is entered from the top end opening of outer shroud blast tube, for make combustion gas and air gas mixture smooth and easy and reposefully outwards and upwards flow in outer shroud blast tube 13, in the present embodiment, combustion gas divides the roof 141 in gas storehouse 14 in inclined-plane downward-sloping from inside to outside, as shown in Figure 3.Combustion gas divides the roof 141 in gas storehouse 14 downward-sloping from inside to outside, guide effect can be played to the mist dividing gas storehouse 14 outwards to spray through combustion gas, gas flow as shown by the arrows in Figure 3, reduce air mixture divides flowing in gas storehouse 14 drag losses in combustion gas, be combined with the fan shape that combustion gas divides gas storehouse 14, to reduce speed when mist enters outer shroud blast tube 13, combustion gas and air are mixed again, further increase the uniformity of combustion gas and air mixing, thus accelerated combustion, improve fuel gas buring efficiency, reduce flue gas.
Preferably, combustion gas divides the roof 141 tilt angle alpha value scope in gas storehouse 14 to be 5 °-15 °.Specifically, the size of this tilt angle alpha value is determined according to the diameter of the fuel gas inlet 11 of air distribution disk 10, learn through repeated combustion working condition tests, the diameter of fuel gas inlet 11 is larger, tilt angle alpha value is less, tilt angle alpha value is advisable with about 10 °, and therefore the present embodiment value is 5 °-15 °.
Be similarly the mist mixing uniformity improved in outer shroud blast tube 13, two combustion gas divide gas storehouse 14 Central Symmetry to arrange.
Combustion gas divides the outer wall of the inner in gas storehouse 14 and inner ring blast tube 12 to connect as one, and connecting portion adopts arc transition; Combustion gas divides the inwall of the outer end in gas storehouse 14 and outer shroud blast tube 13 to connect as one, and connecting portion adopts arc transition.Connecting portion all adopts arc transition to connect, and gas is flowed more steadily smooth and easy, resistance is little, is conducive to further mixing.
Two combustion gas divide the area sum in gas storehouse 14 to be 2 times of circle ring area area between inner ring blast tube 12 and outer shroud blast tube 13 to 3 times, then correspondingly the gross area of air duct 15 is 2.5 times of circle ring area area between inner ring blast tube 12 and outer shroud blast tube 13 to 3.5 times, learn through repeated combustion working condition tests, this combustion gas than column distribution divides gas storehouse 14 and air duct 15 can take into account the air inflow of combustion gas, the air inflow of air can be taken into account again, make the mist of combustion gas and air more be conducive to burning thoroughly, improve efficiency of combustion.
The present embodiment also proposed a kind of burner, comprises air distribution disk 10, and the embodiment of concrete structure see the utility model air distribution disk of air distribution disk 10 and the description of accompanying drawing 1 to 3, do not repeat them here.
The present embodiment also proposed a kind of gas-cooker, comprises burner, and burner is burner described in the present embodiment.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
