Problems solved by technology
Especially when the customer has multiple oxygen use points, and at least one oxygen use point has a huge change in oxygen demand such as intermittent oxygen use, it will make it difficult to adjust the original design and selection system to meet its use requirements. It will directly affect the overall effect of the oxygen-enriched combustion-supporting process, and in a sense, it will seriously restrict the application of the oxygen-enriched combustion-supporting system using this separation method

Embodiment Construction
[0031] The difference between the present invention and the prior art will be described below in conjunction with the accompanying drawings, and the present invention will be further described. In the attached picture:
[0032] AF01 is an air filter, which can be in various forms, including fiber form, filter material form, bag filter, preferably self-cleaning form or various combinations of filters, used to filter, clean and enter the membrane The raw material air of the separator ensures the cleanliness requirements of the membrane separator for the raw air.
[0033] V101, V102, V103, V104, and V105 are regulating valves. The regulating valve V101 is used to adjust the air intake of the blower, and V102 is used to regulate the circulation flow back to the high-pressure side (retention side) of the membrane separator after the vacuum pump. The regulating valve V103 is used After adjusting the vacuum pump, it returns to the permeate side of the membrane separator (low pressur...

The invention belongs to the technical field of air separation, and particularly relates to a membrane separation oxygen supplying method and system. The method is to increase a plurality of regulating loops in the existing membrane separation oxygen supplying system, so as to deal with the environment temperature change and extreme situation such as user side intermittent oxygen utilization, then ensuring that the membrane separation oxygen generation can supply oxygen-rich gas with acceptable flow and purity to the user, effectively avoid acute fluctuation or instability of the device of the generated oxygen-rich component or flow due to the applied environment temperature change and the extreme situation such as user side intermittent oxygen utilization during the membrane separation process. The membrane separation oxygen supplying method and the system are simple and feasible, and very suitable for regulation of oxygen-rich combustion supporting process of a furnace or a kiln.
Description
technical field [0001] The invention belongs to the technical field of air separation, and in particular relates to a membrane separation oxygen supply method and system. Background technique [0002] Membrane oxygen enrichment technology is a new separation method gradually developed since the end of the 1970s. It uses the difference in selective permeability of nitrogen and oxygen in dense organic polymer films. When there is a pressure difference or pressure ratio on both sides of the membrane, , the gas with fast permeation rate in the mixed gas, such as water vapor, hydrogen, helium, oxygen, carbon dioxide, etc., permeates the membrane and enriches into oxygen-enriched air on the low-pressure side of the membrane (depending on the oxygen-nitrogen separation coefficient of the membrane material, single-stage separation Oxygen-enriched with a purity of about 23-60% can be obtained), while gases with relatively slow permeation rates such as nitrogen, argon, methane and car...
