Portable integrated controllable chemical oxygen generator

Abstract

The invention discloses a portable integrated controllable chemical oxygen production device, which uses hydrogen peroxide as a raw material to generate oxygen through catalyst catalysis, and consists of a hydrogen peroxide solution storage room, a reaction room (with a built-in catalyst), an oxygen storage room, a buffer and a It is composed of connecting chamber and microporous control device. It is characterized in that: the contact between the catalyst and hydrogen peroxide is controlled by controlling the amount and speed of the hydrogen peroxide solution entering the reaction chamber, thereby controlling the generation speed and amount of oxygen; the hydrogen peroxide solution entering the reaction is controlled by controlling the change of air pressure The volume and speed of the chamber; the change of air pressure is controlled by controlling the size of the oxygen outlet valve and the auxiliary function of the micropore control device; the pressure change of the hydrogen peroxide solution storage chamber is adjusted by the micropore control device and the one-way breathable valve ;The pressure is kept in a safe range by a pressure reducing valve. The invention can make the oxygen generating device small in volume, large in gas production, controllable in process, safe and environment-friendly, and convenient to carry.

Description

technical field [0001] The invention relates to the field of chemical oxygen production, in particular to a chemical oxygen production device which utilizes hydrogen peroxide to prepare oxygen. Background technique [0002] In medical treatment, for some patients with respiratory diseases, patients with cardiovascular system diseases, and other critical patients; Business people and white-collar workers often need to inhale oxygen for treatment or health care. At present, the common oxygen inhalation devices are as follows: 1. Oxygen inhalation in hospitals. The advantage is that the oxygen is stable and clean, controlled by professionals, and the curative effect is definite. The disadvantages are: limited location and time, easy to cross infection. 2. The disadvantage of high-pressure steel cylinders is that no matter it is an ordinary oxygen cylinder or a small oxygen storage cylinder, it can only be used after being decompressed by an oxygen pressure reducing valve. Thi...

AI Technical Summary

Problems solved by technology

Disadvantages: location and time are limited, easy to cross infection

2. The disadvantage of high-pressure steel cylinders is that no matter it is an ordinary oxygen cylinder or a small oxygen storage cylinder, it can only be used after being decompressed by an oxygen pressure reducing valve. This kind of device is relatively heavy and has high pressure, which is dangerous and inconvenient to use

3. The disadvantages of medical oxygen bags are: the amount of inflation is limited, and it is easy to leak, cannot be stored for a long time, and it takes up more space and is inconvenient to carry

4. The disadvantages of small oxygen tanks (such as Airun, etc.) sold in the general market are: due to the material, they cannot withstand high pressure, and the oxygen storage capacity is small, generally 0.5-1 liter, and cannot continuously supply oxygen, and the use effect is not good.

5. The disadvantages of chemical oxygen generators such as Oxygenide sold in the market are: large volume, complicated operation, small oxygen production, and the process cannot be controlled. In addition, the product of the reaction is alkaline liquid, which causes great damage to the environment.

6. Oxygen production mechanism using molecular sieve technology, as well as oxygen production by electrochemical methods, have the disadvantages that they must rely on continuous power supply to supply oxygen, and cannot be carried around

[0003] After researching the above-mentioned common oxygen inhalation device, the inventor of the present invention found that the current market lacks a device that is small in size, compact in structure, easy to use, can be carried around, does not need continuous power supply, and has a large oxygen production capacity and can last continuously. Oxygen supply, process controllable, environmentally friendly and pollution-free portable oxygen inhalation device
