Embodiment Construction
[0013] Such as figure 2 As shown, in the oxygen-enriched air distribution equipment provided by the present invention, it includes three sets of oxygen-enriched air distribution devices 10 connected in parallel. Wherein each first oxygen delivery pipe 15 in each set of parallel oxygen-enriched air distribution devices 10 communicates with one end of the oxygen supply main pipe 13 respectively, and the other end of the oxygen supply main pipe 13 communicates with the oxygen supply device 12. A second oxygen inlet valve 1 and a third pneumatic valve 11 connected in series are sequentially arranged in the main pipe 13 .
[0014] exist figure 2 Among them, the first oxygen delivery pipe 15 is connected in series with the first oxygen inlet valve 5 and the first pneumatic valve 51 in sequence. An air inlet valve 2 is arranged in the air supply pipe 21, and the second oxygen delivery pipe 17 connected in series with the first oxygen inlet valve 5 and the first pneumatic valve 51...

Description
technical field [0001] The invention relates to an oxygen-enriched air distribution device, in particular to a distribution device capable of adjusting the oxygen-enriched concentration in the supplied air. Background technique [0002] In the existing gas manufacturing and production fields in the fields of metallurgy, chemical industry, glass, boilers, etc., it is often necessary to use an oxygen-enriched air concentration distribution device that is deployed by a control device. Oxygen-enriched continuous gasification is an atmospheric continuous gasification process developed on the basis of batch gasification process, and its process and equipment are basically the same as batch gasification. The main preparation process is: the pure oxygen from the air separation unit is mixed with air, according to the needs of different gas raw materials, by adjusting the opening degree of the supply valve, the pure oxygen and air are configured into a rich mixture with a volume rati...
