The advantage that the designed film of the utility model separates oxygenerator is:
1. rational in infrastructure, help miniaturization;
2. reduce pollution, the oxygen generation efficiency height to environment.
In the oxygen generating plant of the utility model applicable to different field.
Description of drawingsFig. 1 is the structure chart that the designed a kind of film of the utility model separates oxygenerator.Fig. 2 is an internal structure schematic diagram among Fig. 1.Fig. 3 is a diffusion barrier structural representation among Fig. 2.
The specific embodiment
A kind of film as shown in Figure 1 separates oxygenerator, mainly by cylindrical outer casing 3, membrane separator 7, oxygen-enriched generator 10, filter course 1,5, inlet duct 6, gas transmission assembly 8, oxygen-enriched air collector 9 constitutes, membrane separator 7 and oxygen-enriched generator 10 are positioned at shell 3, oxygen-enriched generator 10 is a pipe shape Multiporous infiltration tube, oxygen-enriched generator 10 two ends are fixedly installed in the shell 3 by support, outside its wall, be attached with membrane separator 7, its structure such as Fig. 2, shown in 3, membrane separator 7 is a layer structure, roll with anisotropic membrane and fabric complex 12 by high pressure runner partition 11 and to constitute, the filter course 1 and 5 that is used to remove air plankton is installed at the two ends of shell 3, the filter course 5 outer inlet ducts 6 that are equipped with of shell 3 one sides, inlet duct 6 is an air exhauster, close inlet duct 6 ends of oxygen-enriched generator 10 are blind end, the other end is connected with gas transmission assembly 8 by air delivering pipeline 13, and gas transmission assembly 8 is the blower fan of bleeding, and gas transmission assembly 8 is communicated with impinger 9 by air delivering pipeline 13.
This device is when using, and under the effect of inlet duct 6, air enters in the shell 3 from the external world, and through the selection of gas separation membrane in the membrane separator 7, Oxygen Flow enters in the oxygen-enriched generator 10 through " the infiltration road " of film fabric complex layer.Residual gas then flows out from the other end of shell 3.And the filter course 1 at shell 3 two ends and 5 can carry out the filtering processing of physics or chemical mode to air, with solid-state floating thing filterings from contain the oxygen air such as airborne small amount of nitrogen oxygen compound, hydrocarbon, water vapour, inert gas and other micro-gaseous material components and a small amount of floating dust.Make drying, pure, the nonhazardous of the gas change that enters into shell 3 spaces.
Above-mentioned membrane separator 7 be the membrane module of reeling, remove above-mentioned multilayer planar formula structure, also can adopt structures such as screw winding formula fiber bundled tube as required.
When in the practical application oxygen content in the unit volume oxygen-enriched air being had higher the requirement, also can progressively improve concentration by the mode of multistage enrichment.The output oxygen-enriched air of oxygen membrane separator that is prestage is as the input air of back level.The progression of enrichment is many more, obtained the oxygen content of oxygen-enriched air high more, finally can obtain pure oxygen in this way.
When in the practical application tolerance of oxygen-enriched air being had bigger the requirement, can consider in peer, to be set up in parallel said apparatus, after input air is filtered, be transported to respectively in each separator at the same level, concentrate the unified output of aerogenesis then at place, final stage oxygen enrichment gas outlet.
Either way must reach the time, this device can adopt with multipolarity when above, and every grade of many gas channels mode of work side by side are provided with.So reach and to satisfy the output high-concentration oxygen, the requirement of atm number output can be arranged again.
See that by above-mentioned membrane separation oxygenerator is rational in infrastructure, can satisfy the oxygen rich gas of various different demands by different combinations.
