Problems solved by technology

However, the above-mentioned patent uses a single-inclination inner cylinder, and the change of the flow section cannot well match the above-mentioned pressure loss caused by nitrogen adsorption.
[0008] In addition, the tank structure of the above patent makes the air inlet and outlet ports located below the tank body, while the vacuum port is located on the tank top, which leads to incomplete nitrogen discharge during the reverse discharge process , and in the pressure equalization process after reverse discharge, it is difficult for the high oxygen-containing pressure equalization gas to enter the outer adsorbent area, which leads to the difference in bed performance

Abstract

The invention provides a high-efficiency medical oxygen generator and an oxygen generator method, comprising at least two adsorption tanks (1) filled with adsorbents (2), gas pipelines connected to the adsorption tanks (1), and a A number of control valves on the gas pipeline; each of the adsorption tanks (1) is composed of a concentrically arranged large cone (3) and a small cone (4) and the tank, large cone, small cone The positioning components between or inside the cones are divided into three sections of adsorbent layers: upper, middle and downstream; the large cone (3) and the small cone (4) both adopt an inverted frustum structure, and the large cone ( 3) The inclination is greater than that of the small cone (4), so that the upstream section and the midstream section can compensate the pressure drop caused by nitrogen adsorption through the change of the flow section, and the compensation rate of the upstream section is greater than that of the midstream section.

Description

technical field [0001] The invention relates to a medical device, in particular to a high-efficiency medical oxygen generator and an oxygen production method. Background technique [0002] Oxygen-enriched air inhalation therapy is an important means in the treatment of cardiovascular and cerebrovascular and respiratory diseases. Double tower pressure swing adsorption oxygen production (ie PSA oxygen production) is a kind of air as raw material and molecular sieve as adsorbent. One tower is used to adsorb nitrogen at high pressure to generate oxygen-enriched air, and the other tower is low-pressure or atmospheric pressure reverse discharge and release. The nitrogen adsorbed by the adsorbent completes the oxygen production process of adsorbent regeneration. [0003] Different from the cryogenic oxygen production process, the PSA oxygen production process relies on the difference in the adsorption performance of molecular sieve adsorbents for nitrogen and oxygen in a high pres...
