How to choose an oxygen concentrator？

Oxygen concentrators are medical devices designed to provide supplemental oxygen to individuals with respiratory conditions. They are essential for patients suffering from chronic obstructive pulmonary disease (COPD), asthma, pneumonia, and other illnesses that impair lung function. Understanding the different types of oxygen concentrators available can help patients and caregivers make informed decisions about their oxygen therapy needs. This article explores the various types of oxygen concentrators, their features, and their applications.

Hydrogen Oxygen Generator

Extracting oxygen through the chemical reaction of electrolyzing water requires constant addition of water. This kind of oxygen concentrator has a short service life, cannot be tilted or moved at will, consumes a lot of power, and usually needs to be used under the guidance of professionals.

The principle of the hydrogen oxygen generator is to use electrolytic water technology to decompose water into hydrogen and oxygen through electrochemical reactions in the electrolytic tank‌. The specific process is as follows:

• ‌Electrolysis Reaction‌: When direct current passes through water, water molecules undergo an electrolysis reaction to generate hydrogen and oxygen. In the electrolyzer, water is decomposed into hydrogen and oxygen. The hydrogen moves toward the cathode to produce hydrogen; the oxygen moves toward the anode to produce oxygen‌.
• ‌Electrode reaction‌: At the cathode, hydrogen ions gain electrons and become hydrogen gas (H₂); at the anode, hydroxide ions lose electrons and become oxygen (O₂)‌.
• Gas Collection‌: Hydrogen is discharged through the drainage device, while oxygen is transported to where it is needed through the gas supply device. Oxygen enters the oxygen storage tank through the pipeline for users to use‌.

Hydrogen Oxygen Generator are widely used in many fields:

• Medical Field‌: Used to provide additional oxygen supply, especially for patients with respiratory diseases‌.
• Industrial field‌: used in production processes that require oxygen as raw material‌.
• Household field‌: Suitable for elderly people who need oxygen therapy or patients with respiratory diseases‌.

Advantages and Disadvantages of Hydrogen Oxygen Generator:

Advantage:

• ‌Efficient‌: Able to provide oxygen continuously and stably.
• Safety‌: Relatively simple to operate and easy to maintain.

Disadvantage:

• High energy consumption‌: The electrolyzed water oxygen generator consumes a lot of electricity.
• Higher costs‌: Equipment purchase and maintenance costs are high.

By understanding the working principle of the electrolyzed water oxygen generator, its application fields, advantages and disadvantages, you can better select and use this equipment.

Oxygen-rich membrane oxygen generator

The polymer oxygen-rich membrane is used to collect oxygen by allowing oxygen molecules to pass through preferentially, but the oxygen concentration is generally not high, so it is suitable for daily oxygen therapy and health care.The principle of the oxygen-rich membrane oxygen generator is to use a special membrane material (oxygen-rich membrane) to separate the oxygen in the air to achieve the purpose of producing oxygen. Oxygen-rich membrane is a special membrane material with a high concentration of oxygen molecules inside, which can selectively allow oxygen to pass through and prevent other gases from passing through.

The working process of the oxygen-enriched membrane oxygen generator is as follows:

• Air Compression‌: Air is compressed into high-temperature and high-pressure gas through a compressor.
• Cooling and liquefaction‌: The high-temperature and high-pressure air is cooled through the condenser and becomes liquid.
• Evaporative Separation‌: Liquid air evaporates through the evaporator and becomes gaseous.
• Oxygen-rich membrane separation‌: During the evaporation process, oxygen molecules are separated from the original air through the selective permeation of the oxygen-rich membrane, thereby producing high-concentration oxygen.
• Concentration adjustment‌: Control the concentration of oxygen through the regulating valve to reach the required standard‌

The advantages of oxygen-enriched membrane oxygen generators include:

• Efficient‌: Able to separate oxygen efficiently.
• Portable‌: Small size, light weight, simple to operate, can be used anytime and anywhere.
• Safety‌: The oxygen production process does not require any chemical reagents and does not produce any harmful substances.
• Environmentally friendly‌: The entire process does not produce pollutants and is environmentally friendly

Oxygen-enriched membrane oxygen generators are suitable for various places that require oxygen, such as plateaus, mountains, islands and other places lacking oxygen, as well as hospitals, nursing homes, homes and other places. In addition, it can also be used in industrial oxidation reactions, combustion and other processes, as well as oxygen supply in military, aerospace and other fields.

‌Chemical reaction oxygen generator

Producing oxygen through a specific proportion of chemicals is expensive and dangerous, and is not suitable for home use.

‌The principle of chemical reaction oxygen generator‌ is to produce oxygen through chemical reaction. Its product structure mainly includes reactors, cooling systems, absorbers, filtration systems and control systems. The specific working steps are as follows:

• Chemical reaction‌: Add necessary chemicals, such as hydrogen peroxide, salt and acid, etc., and add catalysts to the reactor to promote the rapid chemical reaction‌.
• Oxygen Generation‌: The reaction produces oxygen, which flows out of the reactor and enters the cooling system to cool the oxygen‌.
• Harmful gas removal‌: The cooled oxygen enters the absorber and absorbs harmful gases that may be present in the air‌.
• Filter system‌: Oxygen passes through the filtration system to further remove harmful substances‌.
• Flow adjustment‌: Finally, the control system adjusts the flow of oxygen to meet different usage needs‌.

Advantages of chemical reaction oxygen generator:

• Efficient and fast‌: A large amount of oxygen can be produced in a short time‌.
• Environmental protection and energy saving‌: Only chemical substances are used, no need to consume a lot of energy‌.
• Simple operation‌: The equipment is highly automated and easy to maintain‌.Usage scenarios

Chemical reaction oxygen generators are widely used in the following fields:

• Industrial manufacturing‌: used to produce oxygen to meet industrial needs‌.
• Environmental Treatment‌: Used to purify the air and remove harmful gases‌.
• Medical care‌: Used to supply oxygen and improve the level of medical care‌.
• Laboratory Research‌: Used for scientific experiments to meet scientific research needs‌.

Molecular sieve oxygen generator

Utilizing the adsorption and desorption technology of molecular sieves to extract oxygen directly from the air, it is safe, environmentally friendly and low-cost. It is a commonly used oxygen production method at present.

The working principle of the molecular sieve oxygen generator is mainly to achieve the separation and preparation of oxygen through the adsorption effect of the molecular sieve‌. Its working process can be divided into the following steps:

• Compression system‌: Compress air to a certain pressure so that nitrogen and oxygen in the air can be separated.
• Cooling system‌: Cool the compressed air to a temperature suitable for molecular sieve adsorption.
• Purification system‌: Removes moisture, dust and other impurities in the air to avoid affecting the adsorption effect of the molecular sieve.
• Molecular sieve adsorption system‌: When the compressed air passes through the molecular sieve, the molecular sieve selectively adsorbs nitrogen in the air and allows oxygen to pass through, thereby achieving the separation and preparation of oxygen‌.

Molecular sieve oxygen generators are widely used in many fields:

• Industrial production‌: Used for the preparation of high-purity oxygen to improve production efficiency.
• Medical Assistance‌: For the treatment and rehabilitation of patients.
• ‌Scientific Experiment‌: Used for scientific research and experiments.
• Environmental monitoring‌: used for environmental monitoring and protection‌.
