Description
Technical field
The utility model relates to gas purification field, particularly relates to nitrogen purification.
Background technology
Nitrogen is a kind of gas of colorless and odorless under normal condition, and usually nontoxic.78.12% (volume fraction) of nitrogen duty gas total amount, the gas density under normal conditions is 1.25g/L, and nitrogen is insoluble in water, at normal temperatures and pressures, approximately only dissolves the nitrogen of 0.02 volume in 1 volume water.Nitrogen is the gas of difficult liquefaction.
Nitrogen gathers to have in industrial production and greatly acts on, and can need nitrogen in a lot of industrial production, and therefore purification nitrogen has become the urgently problem that solves of people.
The way of existing nitrogen purification generally adopts, and liquefied air extracts nitrogen, a standard atmosphere pressure, utilize nitrogen purification nitrogen different from the liquefaction temperature of oxygen, but the nitrogen gas purity that this way is extracted is lower.
Some are also had to adopt the way of pressure swing adsorption air separation, namely be raw material with air, sorbent material is made with carbonaceous molecular sieve, utilize carbonaceous molecular sieve to the characteristic of the oxygen in air and nitrogen adsorption selection, use pressure-variable adsorption principle (pressurized adsorbent, decompression desorb also makes regenerating molecular sieve) and at normal temperature, oxygen is separated to produce nitrogen with nitrogen, the nitrogen gas purity that this method is produced is about 97% ~ 99.5%, but purity still can not reach the requirement that some special occasions use nitrogen.
