Problems solved by technology
[0003] However, the existing gas dilution methods and devices mostly use multi-channel pipelines to mix in the pipeline according to the required flow rate. This method is accurate but the total amount of dilution is limited. If the dilution ratio is large, the power consumption will be large and the space occupied will be large. In addition, it is easy to cause potential safety hazards caused by local concentration changes caused by blockage of the dilution point

Embodiment Construction
[0026] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.
[0027] The high-efficiency gas dilution method of the present invention is suitable for mixing the dilution gas B in a large stable gas A flow field with isolated spaces around the axial direction. Gas B is sprayed into the flow field of gas A through the flow regulating device, pipelines, and multiple injection devices 1 . figure 1 The specific example given in the sintering machine is that air (ie, gas A) flows from top to bottom in the upper part of the sintering machine bed, that is, in a large space with a rectangular cross section, and it is a stable flow field.
[0028] The multiple groups of spraying devices 1 in the present invention are evenly distributed at equal intervals in the gas A flow field according to a certain rule. figure 2 A specific embodiment is given in , in wh...

The present invention relates to a method and device for rapidly, uniformly and large-ratio dilution of single-component or multi-component gas at a certain concentration in a stable gas flow field in a large space, including a stable gas flow field and a spraying device, wherein the There is a stable flow field gas A in the stable gas flow field, and there are multiple injection devices for injecting gas B into the stable flow field gas A. The high-efficiency gas dilution method and device provided by the present invention solve the problem of rapid, uniform and large-ratio dilution of gas in a large space that cannot be realized by the existing gas dilution technology. The dilution ratio can be adjusted by adjusting the flow rate of gas B. After diversion and diffusion, it is quickly and fully mixed with gas A, and the combination of multiple injection devices makes the dilution ratio of gas B have a good consistency in a large space.
Description
technical field [0001] The invention relates to a gas dilution device and a method thereof, in particular to a system for uniformly and quickly mixing and diluting a single-component or multi-component gas at a certain concentration under a large-space stable flow field. Background technique [0002] Spraying hydrogen-containing gas fuel on the surface of the material layer at the front of the sintering machine can improve the sintering mineral output and quality, and reduce the use of coke powder or coal powder. It is an energy-saving and environmental protection technology for sintering. However, in order to uniformly inject gaseous fuel and quickly mix with air on a sintering machine with a large area, there is a technology for efficient gas dilution in a large space. This technology not only needs to achieve a large amount of diluted gas and high dilution quality requirements, but also ensures that the gas fuel quickly and safely crosses the explosive concentration area ...
