Abstract

The invention discloses an argon production and preparation system, and relates to the technical field of air separation devices. The argon production and preparation system comprises an air storage tank, a first separation tower, a second separation tower and a liquid conveying pipeline, the bottoms of the first separation tower and the second separation tower are fixedly connected with the liquid conveying pipeline, a temperature sensor and a pressure sensor are sequentially arranged on the surface of a sealing cover, and a mounting hole is fixedly connected with an ice water pipe. Accordingto the argon production and preparation system, air in the air storage tank is introduced into the first separation tower, the inlet and outlet amount of ice water is controlled through the opening degree of a control valve, oxygen with the boiling point of 90.2 K is liquefied, the liquid oxygen enters a liquid oxygen storage tank through a first liquid outlet pipeline, mixed gas is pumped into the second separation tower through a gas pump, argon with the boiling point of 87.3 is liquefied, the liquid argon enters a liquid argon storage tank through a second liquid outlet pipeline, nitrogenis compressed through a compressor, the liquid nitrogen enters a liquid nitrogen storage tank through a second gas outlet pipeline, and the argon, the nitrogen and the oxygen are collected and storedseparately.

Description

technical field [0001] The invention belongs to the technical field of air separation devices, in particular to an argon production and preparation system. Background technique [0002] Argon is a colorless, odorless monatomic gas with a relative atomic mass of 39.948. Generally, after liquefaction of air, argon is produced by fractional distillation. Argon is 1.4 times denser than air and 10 times denser than helium. Argon is an inert gas that does not react chemically with other substances at room temperature, and is insoluble in liquid metals at high temperatures. It can show its superiority when welding non-ferrous metals. It can be used for bulb inflation and arc welding of stainless steel, magnesium, aluminum, etc., that is, "argon arc welding"; for special metals such as aluminum, magnesium, copper and their alloys and stainless steel in aircraft manufacturing, shipbuilding, atomic energy industry and machinery industry When welding, argon is often used as a weldin...
