The invention discloses a pressure swing adsorption oxygen production and oxygen purification integrated system which mainly comprises a compressed air pipeline, a pressure swing adsorption oxygen producer, a buffer tank, an oxygen purification host and an oxygen storage tank, wherein the compressed air pipeline is communicated with the inlet of the pressure swing adsorption oxygen producer; the outlet of the pressure swing adsorption oxygen producer is communicated with the buffer tank through a pipeline; the buffer tank is communicated with the inlet of the oxygen purification host through a pipeline; the outlet of the oxygen purification host is communicated with the oxygen storage tank through a pipeline; the oxygen storage tank is communicated with the buffer tank through a pipeline and is also communicated with a return tank through a pipeline; and a valve for controlling connection and disconnection is arranged on each pipeline. The invention further provides a method for producing and purifying oxygen by utilizing the integrated system. The system has the beneficial effects that exhaust discharged by the oxygen purification host is recovered by the return tank and input into the pressure swing adsorption oxygen producer to serve as resurgent gases, so that the oxygen recovery rate of the whole system is greatly improved, the regeneration effect is improved, and the oxygen purity is improved.

The therapeutic instrument includes electrolytic ozone generator, super pure water treater, oxygen-water mixing chamber and cleaning head. The super pure water treater has water outlet connected to the water inlet of the oxygen-water mixing chamber via pipes; the oxygen-water mixing chamber has air outlet, air (water) inlet and water outlet connected to the anode water inlet of the electrolytic ozone generator; the electrolytic ozone generator has anode water (air) outlet connected to the air (water) inlet of the oxygen-water mixing chamber and the cleaning head; and one circulating pump is connected in the pipeline between the electrolytic ozone generator and the oxygen-water mixing chamber. The present invention has high oxygen purity, high treating effect, reasonable structure and other advantages.

The invention discloses a spherical floating bin type chemical oxygen generation device.The chemical oxygen generation device which adopts catalysts for catalyzing decomposition of hydrogen peroxide to generate oxygen comprises a hollowed-out spherical base, a floating bin, a reaction chamber, a flexible oxygen delivery pipe, a hydrogen peroxide storage chamber, an oxygen outlet control valve, a two-way pressure reducing valve and the like.The chemical oxygen generation device is characterized in that the floating bin is in a closed double-shell hollow structure, the floating bin and the reaction chamber are integrated and always positioned above the base under the buoyancy action, and the hydrogen peroxide enters the reaction chamber from the lower position all along; by the hollowed-out spherical base and an inner shell of the reaction chamber, the floating bin and the reaction chamber are capable of rotating all around, and the hydrogen peroxide is allowed to enter the reaction chamber freely; oxygen generation is controlled by control of contact of the hydrogen peroxide with the catalysts in the reaction chamber; the hydrogen peroxide is controlled to enter or get out of the reaction chamber by control of the air pressure of the reaction chamber; by the two-way pressure reducing valve, intensity of pressure is maintained in a reasonable range to guarantee safety.The spherical floating bin type chemical oxygen generation device has the advantages of small size, convenience in use, portability and stability and sufficiency in oxygen generation.
