Rotating molecular sieve minisize pressure swing adsorption oxygen making device

Abstract

A rotary molecular sieve minitype transformation adsorption oxygen production device includes a molecular sieve container and a rotating mechanism. The molecular sieve container includes a rotary shaft in the center of the container and mandrils uniformly arranged in the molecular sieve container. The mandrils separate the molecular sieve container into a plurality of molecular sieve channels. The rotary shaft is connected with the rotating mechanism. A gas inlet cover includes an air inlet cushion chamber of the gas inlet cover, a pressure equalizing chamber of the gas inlet cover and a gas discharge cushion chamber of the gas inlet cover. The gas inlet cushion chamber of the gas inlet cover is communicated with a gas compressor. The air discharge cushion chamber of the gas inlet cover is connected with a rich nitrogen outlet. The gas discharge cover includes an inlet cushion chamber of a gas cover, a pressure equalizing chamber of a gas discharge cover and a discharge cushion chamber of the gas discharge cover. The discharge cushion chamber of the gas discharge cover is connected with the rich nitrogen outlet. The invention changes a paired tower into a single tower which has decreased size remarkably. The driving force for the molecular sieve container to rotate is low pressure purgative gas. Under the condition of fully guaranteeing the best washing pressure, the invention has made full use of the pressure energy of the purgative gas and is beneficial to improve effect and reduce energy consumption of the whole system.

Description

technical field [0001] The invention belongs to a pressure swing adsorption oxygen making device in the field of air separation, in particular to a rotary molecular sieve micro pressure swing adsorption oxygen making device. Background technique [0002] Adsorption separation is a process in which the multi-component fluid mixture is fully contacted with the solid surface of the adsorbent, and there are different forces between the components of the mixture and the surface of the adsorbent, so that the components with stronger force are adsorbed on the surface of the adsorbent. The process of enrichment and separation from weaker components. At a constant temperature, the curve of the adsorption capacity of the adsorbent changing with the pressure is called the adsorption isotherm. [0003] The pressure swing adsorption process is carried out along the adsorption isotherm based on the principle of adsorption and separation, and the adsorption and desorption are carried out ...

AI Technical Summary

Problems solved by technology

②Because the internal current is very large, there are unsafe factors

③ The quality is unstable, because the electrolyte is alkaline and will react with carbon dioxide in the air (carbonation), which will cause the voltage to increase, and the electrode membrane is prone to leakage

④The positive electrode is generally made of foamed nickel, which will decompose and pulverize under the action of electric current, causing the current to fail

The flow rate is too small to meet medical requirements

market The price is 3580~1988 yuan, and the use cost is high
