Abstract

The invention discloses a high-efficiency industrial oxygen production system and an oxygen production process, comprising an air purification cylinder, a refrigeration unit, a condenser heat dissipation unit, a low-temperature conduction heat preservation unit, a pressure tank and an oxygen filter unit; one end of the air purification cylinder is connected to an air inlet , and the other end of the air purification cylinder is connected to the inlet of compressor two through air guide pipe one, the outlet of said compressor two is connected to the top of the pressure tank through air guide pipe two, and the air guide pipe two is connected in series with an intake solenoid valve, so The top of the pressure tank is connected with a nitrogen outlet pipe, and a nitrogen solenoid valve is connected in series on the nitrogen outlet pipe, and the top of the pressure tank is also connected to the top of the oxygen filter unit through an oxygen outlet pipe; the air can be discharged in advance. Purify, get rid of dust and moisture, avoid the impact on oxygen production, and have high refrigeration efficiency for liquefaction containers, thereby speeding up air liquefaction efficiency, improving oxygen production efficiency, and using oxygen-enriched separation membranes to further refill liquefied oxygen Improve oxygen purity.

Description

technical field [0001] The invention relates to the technical field of industrial oxygen production, in particular to an efficient industrial oxygen production system and an oxygen production process. Background technique [0002] Since the air contains about 21% oxygen, it is the cheapest and best raw material for industrial production of oxygen. Industrial oxygen production adopts the method of separating liquid air: pressurizing under low temperature conditions, turning the air into liquid air, and then evaporating. Since liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen evaporates from the liquid air first, leaving mostly liquid oxygen. Since the boiling point of nitrogen is -196°C, which is lower than that of liquid oxygen (-183°C), nitrogen evaporates from liquid air first, leaving mostly liquid oxygen. Most of the current industrial oxygen production adopts this technology, but the quality of the air is difficult to control, the air contains...
