Radial air inlet type turbulence intelligent adjustable adsorption type oxygen enriching device

Abstract

The present invention adopts radial air admission turbulence-like structure, mixed adsorbent technology and intelligent special-purpose computer programmable controller for dynamic analog pressure swing adsorption circulation process, and designs the radial air admission turbulence-like adsorption tower structure form according to the requirements, and can improve the non-uniform air flow whose flow rate distribution is parabolic and make it into uniform air flow whose flow rate distribution is log curve from so as to make air flow distribution more reasonable and more stable. Said computer programmable controller can dynamically and intelligently regulate oxygen purity, and can make its purity be greater than or equal to 25%. Said invented equipment can be operated at normal temp. and low-pressure, can be moved, after it is started for 10 min.

Description

1. Technical field [0001] The invention belongs to the field of operation technology, and further relates to a small multi-purpose oxygen-enriching device for intelligently adjustable pressure-swing adsorption type air separation of radial intake turbulent flow. 2. Background technology [0002] Currently used oxygen enrichment device has the following deficiencies: [0003] 1. At present, hospitals and household oxygen are produced by low-temperature method, transported by high-pressure gas cylinders, or supplied by liquid gas storage tanks, which is uneconomical, inconvenient, and unsafe to use, especially for hospitals in remote areas where oxygen cannot be supplied, which brings many difficulties; [0004] 2. The adsorption cycle process of the existing oxygen enrichment device is a fixed relationship; [0005] 3. The adsorbent is single granular, with low adsorption capacity; [0006] 4. The existing oxygen enrichment device adopts axial air intake, and the operation...

Problems solved by technology

[0003] 1. At present, hospitals and household oxygen are produced by low-temperature method, transported by high-pressure gas cylinders, or supplied by liquid gas storage tanks, which is uneconomical, inconvenient, and unsafe to use, especially for hospitals in remote areas where oxygen cannot be supplied, which brings many difficulties;

[0004] 2. The adsorption cycle process of the existing oxygen enrichment device is a fixed relationship;

[0005] 3. The adsorbent is single granular, with low adsorption capacity;

[0006] 4. The existing oxygen enrichment device adopts axial air intake, and the operation process is unstable, which cannot meet the product requirements;

[0007] 5. Existing aquaculture uses an air pump to supplement gas oxygenation (purity is 21%), which cannot meet the high-efficiency and high-quality aquaculture requirements of oxygen-enriched gas;

[0008] 6. The gas flow distributor in the adsorption column of the original oxygen enrichment device has a single structure, and the gas flow is parabolic and unevenly distributed. After long-term operation, the product purity requirements cannot be guaranteed
