Recently, good news came from the State Intellectual Property Office, Qingdao Guolin Technology Group joint stock company declared "pressure swing adsorption oxygen generation device and oxygen production method" successfully obtained the national invention patent authorization.

The invention provides a pressure swing adsorption oxygen generating device and an oxygen generating method, which can directly satisfy the oxygen pressure and concentration required for the operation of an ozone generator. The oxygen generating device comprises a Roots blower, a Roots vacuum pump, a first adsorption tower and a second adsorption tower. The air is connected to the air inlet of the Roots blower and the air inlet of the Roots vacuum pump. The first pipeline is provided with a first control valve, the second pipeline is provided with a second control valve, and the first pipeline is connected to one end of the third pipeline. The other end of the third pipeline is connected to the air outlet pipe of the Roots vacuum pump, the third pipeline is provided with a fourth control valve, and the eleventh control valve is provided on the air outlet pipe of the Roots vacuum pump. The connection point between the third pipeline and the air outlet pipe of the Roots vacuum pump is located upstream of the eleventh control valve. The pressure swing adsorption oxygen generating device and the oxygen producing method of the invention can directly reach the oxygen pressure required by the ozone generator, without the need to configure an oxygen pressor, and can reduce equipment investment and cost.

All along, Guolin Technology has been continuously strengthening its scientific and technological innovation work and driving development with innovation. The acquisition of this invention patent is not only a demonstration of the company's independent research and development capabilities, but also conducive to the company to further improve the intellectual property protection system, form a continuous innovation mechanism, and enhance the company's technical strength and core competitiveness.
