Medical oxygen-making system with standby power supply

Abstract

The invention discloses a medical oxygen-making system with a standby power supply. The system comprises a central oxygen-making system and a power supply system used for powering on the central oxygen-making system. The power supply system comprises a mains-supply power supply and a standby power supply. The standby power supply adopts a solar photovoltaic cell curtain wall. The solar photovoltaic cell curtain wall comprises photovoltaic modules arranged on a wall. Each photovoltaic module includes a plurality of sets of frame type solar cells and connecting pieces used for connecting and fixing each frame type solar cell. Each frame type solar cell comprises a frame and a solar cell sheet fixedly arranged in the frame. The medical oxygen-making system of the present invention has the following advantages: each frame type solar cell is simple, convenient and feasible to assemble and splice, so that a required shape can be realized through quickly combining and splicing up all frame type solar cells. The frame type solar cells are laid on the outer wall of a building at each hospital, and are strong and reliable in assembly strength. The application range of photovoltaic cells is enlarged, so that photovoltaic cells can be used as a stable and reliable standby power supply for the medical oxygen-making system.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a medical oxygen production system with a backup power supply. Background technique [0002] The medical center oxygen production system is also called the medical molecular sieve pressure swing adsorption PSA oxygen production system. It uses molecular sieve as the adsorbent and uses ambient air as the raw material through the pressure swing adsorption method. The adsorption capacity of nitrogen (adsorbate) increases, and the adsorption capacity of nitrogen in the air decreases during decompression, forming a rapid cycle process of pressure adsorption and decompression desorption, so that oxygen and nitrogen in the air can be separated, while in the air Carbon dioxide, gaseous acids and other gaseous oxides, etc., are all substances with strong molecular polarity, and it is difficult to pass through molecular sieves, so that the purity of oxygen produced can reach m...

Problems solved by technology

[0004] Patent document CN104310315A discloses a medical center oxygen production system and its use method. The system is energy-saving and efficient, safe and reliable, easy to operate, does not require manual on-duty, and is fully automated, avoiding the production of molecular sieve powder after the oxygen generator is used for a long time. Problems such as substandard oxygen quality and insufficient flow

But there are still some deficiencies: most of the existing medical oxygen generation systems use a single line for power supply, and once the power fails, the entire oxygen generation system will collapse; so for the stable and reliable use of the system, a reliable backup power supply is also needed

However, in existing hospitals, especially old hospitals that have been established for a long time, there is not enough laying space on the roof, which limits the use of this kind of backup power supply
