The invention discloses a modularized oxygen production device based on a hollow fiber ceramic oxygen permeation membrane. The modularized oxygen production device is formed by mounting and connecting a plurality of hollow fiber membrane bundle elements in parallel in a high-temperature furnace, wherein a heating unit is independently arranged in the high-temperature furnace corresponding to each hollow fiber membrane bundle element; each hollow fiber membrane bundle element comprises a shell, an upper cover, a plurality of hollow fiber ceramic oxygen permeation membrane pipes, a membrane bundle fixing base and a membrane bundle fixing disc; one ends of the hollow fiber ceramic oxygen permeation membrane pipes are sealed, the other ends of the hollow fiber ceramic oxygen permeation membrane pipes are opened, the hollow fiber ceramic oxygen permeation membrane pipes are fixed on the membrane bundle fixing disc and are double sealed through an organic sealant and an inorganic sealant. The modularized oxygen production device is of a reasonable structure, the independent working capacity of each membrane bundle element is strong, the number of the membrane bundle elements can be controlled according to demanded oxygen quantity, the operation and the maintenance are easy, and the practicability is relatively high.
Description
technical field [0001] The invention belongs to the category of ceramic oxygen-permeable membrane separation air oxygen-generating devices, and specifically relates to a modular oxygen-generating device based on hollow fiber ceramic oxygen-permeable membranes. Background technique [0002] Nowadays, pure oxygen is widely used in industrial production and other fields. The application of pure oxygen can increase production, reduce emissions, and reduce costs, and has a positive effect on the efficient use of resources and environmental protection. Traditional oxygen separation mainly adopts air low temperature fractionation process (Cryogenic Separation) and pressure swing adsorption method (Pressure Swing Adsorption), but usually has large equipment investment, high power consumption and low efficiency. In recent years, the research on oxygen production of ceramic oxygen permeable membranes has made great progress. When there is a certain oxygen concentration gradient on bot...
