Description

Technical Field [0001] The present invention relates to an adsorbent bed for gas generators,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adsorption bed for a gas generator, and more particularly, to an adsorption bed for a gas generator using a method of allowing only gas to permeate without generating moisture during gas generation.

Today, gas generators are used in many different applications. For example, an oxygen generator, which is one of the gas generators, is most often used to assist the recovery of fatigue and activation of cells accumulated in the daily life of modern people by supplying oxygen to an enclosed space of an office or a home. In addition, medical gas generators, automotive gas generators, and experimental gas generators are widely used.

In order to generate the gas in this way, PSA (Pressure Swing Adsorption) method is generally used, and a membrane method, an electrolytic method, or the like is also used.

Among them, the PSA type gas generator is a device for separating the gas in the air by utilizing the selective adsorption ability of the adsorbent (Zeolite Molecular Sieve, zeolite). It is a device that continuously changes the pressure of the adsorption bed and continuously operates the adsorption, . That is, when the pressurized air is blown into the adsorbent bed filled with the adsorbent, the gas having low adsorption selectivity is discharged at the outlet of the adsorbent bed, and the adsorbent bed adsorbing the specific component is decompressed, , Detachment).

A method of generating a gas by separating a specific gas from a mixed gas is commercially available in a gas separation membrane method and a pressure swing adsorption method in which a pressure difference is applied to an adsorbent. Among them, the pressure swing adsorption method produces a hatching gas by applying a pressure difference to an adsorbent such as zeolite or carbon molecular sieve having selective adsorption to a specific gas. The pressure difference is a pressure difference between PSA (Pressure Swing Adsorption), Vacuum Pressure VSA, and Combination VPSA.

In the case of producing a high concentration of gas for industrial use, most of the adsorption beds including the adsorbent are installed in the form of a tower and operated in conjunction with a plurality of valves. However, when they are applied to medical or household appliances such as small oxygen concentrators It should be designed differently from industrial because both size and economy are considered. Accordingly, the adsorption bed used in the pressure swing method uses a minimum number of valves and devices, and efforts have been made to simplify as much as possible. In the case of the PSA system operated at atmospheric pressure or higher, it is known to form a check valve for flowing a fluid only in one direction with a microtubule serving as an equilibrium valve in an adsorption bed by using a metal material.

Unlike the case of the PSA system operated at above atmospheric pressure as described above, in the case of the adsorption bed used in the VSA process to receive the vacuum pressure, since it is applied to the miniaturization through several process development, the adsorption bed suitable for the VSA process Design is required.

However, the cartridge, which is one of the constituent elements of the adsorption bed, not only shortens the life of the cartridge when the water penetrates in the process of separating the specific gas from the mixed gas and generates gas, So that the performance of the adsorption bed is deteriorated.
