Embodiment Construction

[0017] Attached below figure 1 The present invention will be specifically described.

[0018] Such as figure 1 As shown, the high-concentration molecular sieve oxygen production equipment of the present invention is composed of a dehydration device, an oxygen absorption device and a nitrogen absorption device in series.

[0019] The dehydration device includes: oil-free air compressor (1), steam-water separator (2), two two-position three-way solenoid valves (3, 4), two 5A molecular sieve adsorption columns (A, B), two single To the throttle valve (5, 6), a relief valve (7), the gas tank (8).

[0020] The steam-water separator is an ordinary commercially available steam-water separator, which mainly removes most of the moisture in the air.

[0021] The pore size of 5A molecular sieve is 4.5-5A, which is used to remove the remaining small part of water and some impurities such as carbon dioxide and sulfur dioxide.

[0022] When one 5A molecular sieve adsorption column is in...

Abstract

The invention relates to a high-concentration oxygen generating plant, in particular to a high-concentration medical oxygen generating plant with molecular sieves, comprising a dehydrating device, an oxygen adsorbing device and a carbon adsorbing device which are sequentially serially connected. The oxygen adsorbing device comprises two carbon molecular sieve adsorption columns connected in parallel, a gas tank and a vacuum pump, and the carbon adsorbing device comprises two oxygen molecular sieve adsorption columns connected in parallel, a gas tank and a vacuum pump. The high-concentration medical oxygen generating plant with the molecular sieve adsorption columns adopts the heatless automatic regeneration molecular sieve technology to remove water and harmful gases, such as carbon dioxide, sulfur dioxide and the like, in air. Nitrogen and argon are removed by means of preferentially adsorbing oxygen by the aid of carbon molecular sieves, residual nitrogen is removed by oxygen molecular sieves, and accordingly concentration of the oxygen can reach 99.99% at least. Product oxygen is not used as regeneration gas for realizing vacuum pressure swing adsorption, accordingly, oxygen recycling rate is improved, the service life of the high-concentration oxygen generating plant is prolonged, and the high-concentration oxygen generating plant can be widely used for fields such as industry, hospitals, national defense construction and the like.

Description

technical field [0001] The invention relates to an oxygen generator, in particular to a high-concentration molecular sieve oxygen generator. Background technique [0002] Molecular sieve oxygen production technology has been widely used in the national economy, but most of them use molecular sieves to absorb nitrogen to concentrate oxygen. Since nitrogen accounts for about 78% in the air and oxygen only accounts for about 20.9%, the equipment The volume of the adsorption column is particularly large, and the oxygen concentration is generally around 90%. In particular, the oxygen concentration of medical oxygen production equipment does not meet the standard of greater than 99.5% stipulated by the National Pharmacopoeia, and the service life is limited, resulting in slow promotion. Contents of the invention [0003] The high-concentration molecular sieve oxygen production equipment of the present invention mainly solves the problems of low oxygen production concentration an...
