Abstract

The invention discloses an efficient industrial oxygen production system and an oxygen production process. The system comprises 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 filtering unit; one end of the air purification cylinder is connected with an air inlet, and the otherend of the air purification cylinder is connected with an inlet of a compressor II through an air guide pipe I; an outlet of the compressor II is connected with the top of the pressure tank through an air guide pipe II; an air inlet electromagnetic valve is connected to the air guide pipe II in series; a nitrogen outlet pipe is connected to the top of the pressure tank; and a nitrogen outlet electromagnetic valve is connected to the nitrogen outlet pipe in series, and the top of the pressure tank is further connected with the top end of an oxygen filtering unit through an oxygen outlet pipe.Air can be purified in advance, dust and moisture are removed, the influence on oxygen production is avoided, the refrigeration efficiency of a liquefaction container is high, accordingly, the air liquefaction efficiency is improved, the oxygen production efficiency is improved, and an oxygen-enriched separation membrane can be used for further improving the oxygen purity when liquefied oxygen isrefilled.

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...
