Oxygen generator

Abstract

The invention discloses an oxygen generator capable of randomly recycling unqualified product gas, avoiding emptying, saving the product gas and improving the production efficiency. An adsorption tower A (8), an adsorption tower B (11), a gas storage tank (15) and a silencer are arranged on a base (14) in a case (16); a branch pipe A (7) is communicated with the bottom of the adsorption tower A, a branch pipe B (10) is communicated with the bottom of the adsorption tower B, and the other end of the branch pipe A is mutually butted with the other end of the branch pipe B; a gas inlet pipe (6) is communicated with the butted position of the branch pipe A (7) and the branch pipe B (10); a regeneration gas inlet pipe (1) communicated with a gas outlet pipe A (9) and a gas outlet pipe B (12) is connected with a flow meter (2); the outlet of the flow meter is communicated with a connecting pipe (4) through a regeneration gas pipe (3); the oxygen generator is provided with a return gas pipe (5) connected with an output pipe of the gas storage tank (15); and the other end of the return gas pipe is connected with the regeneration gas pipe (3). The oxygen generator can be used as an industrial or medicinal oxygen generator.

Description

technical field [0001] This invention relates to air separation machinery, particularly oxygen concentrators. Background technique [0002] In recent years, due to the rapid development of pressure swing adsorption (PSA) technology, the application field of pressure swing adsorption oxygen production is also becoming wider and wider. However, since the complete equipment of pressure swing adsorption oxygen production is composed of gas treatment system, gas separation system, gas storage system and various pipelines, the structure of the whole system is relatively scattered, the floor area is large, and the cost of materials required is high. The storage and transportation are troublesome, and it is difficult to meet the requirements of modern enterprises, especially in some emerging industries such as biopharmaceuticals and electronics, which have higher requirements for the product in terms of performance, volume, appearance, etc., and the existing pressure swing adsorptio...

AI Technical Summary

Problems solved by technology

[0004] The present invention not only solves the problems of existing pressure swing adsorption oxygen generators such as scattered structure, large floor space, and troublesome installation, storage and transportation, but also solves the problem that substandard product gas can only be emptied and causes waste. Therefore, the present invention is provided. A kind of oxygen generator, this kind of oxygen generator is not only compact in structure, small in floor area, convenient in installation, storage and transportation, low in cost, and the gas of unqualified products can be reused randomly, thus saving resources
