Description
Technical Field
The utility model belongs to the air purification device field, especially a membrane separation device of air-purifying.
Background
The traditional air purification method adopts a mesh screen form to remove dust in air or uses activated carbon to remove harmful gas in air, and the process is that all gases can permeate through a polymer membrane, gas molecules are firstly adsorbed and dissolved on the high-pressure side surface of the membrane, then are diffused in the membrane by means of concentration gradient, and finally are analyzed from the low-pressure side of the membrane, so that the passing speed of small molecules and molecules with strong polarity (such as water vapor, oxygen, carbon dioxide and the like) is high, and the small molecules and the molecules with strong polarity (such as water vapor, oxygen, carbon dioxide and the like) are enriched on the permeation side of the membrane; the membrane separation is carried out by utilizing the difference of permeation rates of various gases on the polymeric membrane, and the separation driving force is the partial pressure difference of the gases on the two sides of the membrane, so that the membrane gas separation has no phase change and does not need regeneration, and the membrane separation has the advantages of simple equipment, safety, reliability, low operation and maintenance cost and the like. The oxygen-enriched air produced by membrane separation and purification is prepared by taking natural air, enriching oxygen in the air in a physical mode, and making the oxygen concentration be greater than 24% (V/V), and the oxygen-enriched air is sterile, clean, free of any dust, and green oxygen-enriched air with the gas humidity higher than the ambient humidity.
