Composite molecular sieve for separating nitrogen and oxygen

Abstract

This invention relates to the field of nitrogen and oxygen separation technology, and more particularly to a composite molecular sieve for nitrogen and oxygen separation. It includes a molecular sieve cylinder, a liquid collection assembly on the side of the molecular sieve cylinder, and a gas collection assembly on the top of the molecular sieve cylinder. Through the coordinated use of a collection tank, a liquid inlet pipe, and a liquid outlet pipe, the temperature inside the collection tank can be monitored in real time due to the presence of heat dissipation pipes inside the collection tank and a temperature detector installed on the side plate. When cooling is required, cold air is injected into the liquid inlet pipe, and the cold air flows through the heat dissipation pipes and is discharged through the liquid outlet pipe. The heat dissipation pipes are arranged in a ring on the inner wall of the collection tank, which can efficiently cool the liquid inside the tank, thereby improving heat dissipation efficiency. An absorption pump draws the gas into a first conduit, and then the gas flows sequentially through an adsorption tank, a dryer, and a cooling tank, finally entering the gas collection cylinder. The adsorption tank adsorbs impurities in the gas, the dryer reduces the moisture content of the gas by heating, and the cooling tank cools the gas, thereby effectively improving the gas quality.

Description

Technical Field

[0001] This invention relates to the field of nitrogen and oxygen separation technology, specifically to a composite molecular sieve for nitrogen and oxygen separation. Background Technology

[0002] The composite molecular sieve for nitrogen-oxygen separation is a key functional component used to achieve efficient separation of nitrogen and oxygen. Its core lies in utilizing the differences in the adsorption performance of molecular sieves for different gas molecules to achieve precise separation of nitrogen and oxygen components in the air. In practical applications, this composite molecular sieve is usually combined with liquid and gas collection systems to form a complete separation system, which is widely used in fields that require high-purity gases, such as industrial nitrogen production and medical oxygen supply.

[0003] However, traditional separation structures still have certain shortcomings in use:

[0004] 1. The device cannot collect the gas and liquid separated during processing. During the collection process, the generated liquid cannot be cooled, which causes the liquid to easily evaporate due to excessive temperature during collection, affecting the efficiency of subsequent processing.

[0005] 2. When collecting gas, the lack of an effective filtration mechanism can easily lead to unstable gas flow rate, which in turn affects the purity of the separated gas. Therefore, filtration is necessary to improve the quality of separation. Summary of the Invention
