Abstract

In the molecular sieve bed structure used in the small oxygen generator, the conventional method, in which the composed bed is separated or there is no organic coupling with the valve, requires a complicated external connection line and separates nitrogen and oxygen. Was designed to reduce the performance of adsorption and desorption, but the "integrated sheave bed structure" eliminates or reduces complex external connections through the integrated modularity of the bed structure and keeps the pressure swing cycle in optimum condition. It provides a system that facilitates the adsorption and desorption function of and oxygen.

"Integrated Bed System for Oxygen Generator" is designed to integrate the molecular sieve bed (1 + 3) and oxygen tank (2) to facilitate the flow of oxygen separated from the air to facilitate the process of nitrogen adsorption and regeneration of the molecular sieve. It is supposed to perform while maintaining an optimal cycle. In the "Integrated Bed System for Oxygen Generators", the integrated beds are integrally designed with a first bed on the left side, an oxygen tank on the center side, and a second bed on the right side to form a body. The inside of the second bed forms a constant space in a circular shape to fill the molecular sieve.

In the "Integrated Bed System for Oxygen Generators," the basic bed, which is integrally formed, is designed to be opened and closed by two connecting plates. The front front connecting plate (Front) performs the function of introducing compressed air and releasing nitrogen. Purging device) The rear bed is a rear purging device that controls the separated oxygen flow and assists the desorption of nitrogen, and the basic bed performs the pressure conversion process and continues the separation process of nitrogen and oxygen. .

In the "Integrated Bed System for Oxygen Generators," nitrogen is adsorbed as the high pressure air passes through the front purging device through the valve structure and then through the first bed filled with molecular sieves. Oxygen passes and moves to the oxygen tank according to the flow structure of the rear purging device to discharge oxygen from the outlet. At the same time, the second bed on the opposite side of the first bed performs the process of desorption (regeneration) of nitrogen which is already adsorbed to the molecular sieve and prepares for another cycle.

The integrated bed system covers the basic bed through the connecting plate at the front and the rear, eliminating unnecessary external connection lines, minimizes the components, and performs the optimal processing procedure to facilitate the adsorption and desorption of nitrogen. .

Description

An Integrated Beds System for Oxygen Generator

The present invention relates to a mechanical application structure, and more particularly to the 'integrated bed system for oxygen generator' for modularizing the molecular sieve bed structure used in the small oxygen generator.

[Private Technology]

Oxygen generators, which were used for medical and industrial purposes, are expanding their marketability in various fields such as households, automobiles, and water purifiers. Therefore, the performance improvement and the life extension of the molecular sieve bed structure, which play an important role in the small oxygen generator, are of great importance as a technical task.

The molecular sieve bed structure used in the conventional oxygen generator has air dispersion and air dissipation because the bed (1 + 2) and the oxygen tank are independently separated from each other, or even the integrated bed structure is dependent on the conventional valve structure. Nitrogen emissions are taken by a one-way structure. In the bed structure, the conventional method is dependent on the conventional valve and repeats the process of air dispersion while sequentially moving different beds on the left and right sides in the circulation of compressed air inlet and nitrogen discharge.

The conventional valve structure used in the oxygen generator has to reduce the excess waste by dispersing air at high pressure among the two fluids, and smoothly discharge nitrogen. However, in the conventional valve structure, the paths of air dispersion (fluid 1) and nitrogen discharge (fluid 2) are united, so that the air (fluid 1) and the discharged nitrogen (fluid 2) are mixed as the movement path is changed during the air dispersion process. There is a disadvantage in that it does not have the proper time required for nitrogen discharge as a result of which a conflict occurs. At the same time as nitrogen is discharged in the same path, high-pressure air is introduced, so that nitrogen is not discharged smoothly, and mixed with air and used again. As such, the valve structure in which the two fluid flow paths are unified does not relatively smooth the fluid flow, and there is a limit to increase the waste of air by not sufficiently digesting the air circulation.

In the conventional bed structure, since the bed and the oxygen tank are separated from each other, a complicated and unnecessary connection line must be used on the outside, and the nitrogen emission is conflicted or the circulation function is relatively distorted at the inflow stage. In the conventional bed structure, the compressed air passes through the external connection line and passes through the first bed to separate nitrogen and oxygen, and also passes through an orifice and an external connection line connecting the first bed and the oxygen tank to the oxygen tank. It is injected and finally performs the process of oxygen production to the outside through the oxygen outlet.

The improved bed structure is designed to be integrated with the bed and oxygen tank to reduce unnecessary external connection lines. However, the bed structure is used because it uses a conventional valve structure that unites the channels of air dispersion and nitrogen discharge from the outside. There is a limitation that the connection method of the conventional bed structure has no difference, and can not overcome the limitation of the design structure dependent on the conventional valve.

The problem caused by this is that the conventional bed structure is dependent on the conventional valve method, so that the result of the separation process of oxygen and nitrogen is greatly changed by being sensitive to the speed of pressure conversion, pressure state, regeneration time of the molecular sieve, and size of the bed structure. Can be.

As such, the conventional bed structure consumes a lot of components such as unnecessary external connection lines, and even an integrally designed bed structure is dependent on the conventional valve structure, and thus has a decisive influence on air dispersion, nitrogen desorption and discharge, injection regeneration, and oxygen increase. Mitch has the functional limitations of the bed structure.

In order to partially solve this problem, improvement methods are being sought in terms of designing the bed and the oxygen tank as a single unit or reducing components such as external connection lines, but these methods also do not achieve innovative structural improvement depending on the correlation with the valve. It cannot be said that the problems described above are not sufficiently solved because there are limitations that cannot overcome the inherent problems. The level of improvement of the conventional bed structure has a limit that does not change the basic principle or structure, there is currently no "integrated bed system for oxygen generator" that improves the conventional basic principle.

The present invention has been made to solve the above-mentioned problems, by improving the design structure and basic principles of the conventional bed structure used to remove or reduce the unnecessary and unnecessary external components, and is not dependent on the conventional valve structure The technical task is to provide an "integrated bed system for oxygen generators" in order to optimize air dispersion and to improve the function of the oxygen-nitrogen separation process.
