Detailed description of the invention
Describing the present invention below according to accompanying drawing, it is a kind of preferred embodiment in numerous embodiments of the present invention.
Efficient gas dilution process of the present invention is suitable for the stabilizing gas A flow field at a bigger axial surrounding insulating space
Middle mixed diluting gas B.Gas B is sprayed in gas A flow field by flow regulator, pipeline, many group injection apparatus 1.
The specific embodiment be given in Fig. 1 is on sintering machine bed of material top, i.e. air (i.e. gas A) in the large space of a square-section
From up to down flow, and be steady flow condition.
Many group injection apparatus 1 of the present invention are the most equidistantly uniformly distributed in gas A flow field.Fig. 2 gives
One specific embodiment, its many group square mesh points of injection apparatus 1 are arranged, to guarantee gaseous fuel (i.e. gas in large space
Body B) dilution ratio have preferable uniformity.
Along with the sprinkling mouth 4 of injection apparatus 1 presses curve or straight path shuttling movement, the gas B sprayed is also gas A's
Steady flow condition is pressed curve or straight path shuttling movement.Additionally, after gas B is ejected, comb Special guide disperser 5
Reason.After two above measure, gas B quickly mixes with gas A and is diluted.Fig. 3 gives a specific embodiment,
Injection apparatus 1 is sprayed 4,3 Special guide disperser 5 structures of mouth by 3 rotations of 2,3 arms 3 of central tube and correspondence
Become.The sprinkling mouth 4 that gas B rotates arm 3 and correspondence by pipeline through central tube 2,3 sprays, then through inverted " V " font
Quickly mix with gas A after Special guide disperser 5 combing.
The device of the method for the invention regulates dilution ratio by the flow of regulation gas B.
The method also providing for the dilution of a kind of efficient gas, sprays into gas B, by moving incessantly in steady flow condition gas A
Much the biggest ratio diluent gas B of group injection apparatus 1, the final uniform mixing gas mixture obtaining a kind of specific components.Gas A
It is in the space of a bigger axial surrounding isolation, and is rendered as steady flow condition.Gas B passes through flow regulator, pipe
Road and many group injection apparatus 1 spray in gas A flow field.Described many group injection apparatus 1 in gas A flow field according to certain rules etc.
Spacing is uniformly distributed.Often group injection apparatus 1 all includes that the sprinkling mouth 4 of 2,1～10 arm 3 of central tube and correspondence is led with special
