O2/CO2/H2/N2/Ar/He/ Purification Plant
This equipment uses industrial air as the raw material gas and employs catalytic cooling, secondary adsorption, and precision filtration methods to remove impurities, carbon monoxide, carbon dioxide, water vapor, and dust, obtaining high-purity oxygen.
The equipment has a simple structure and good airtightness. The catalyst used (adjusting the working temperature based on the impurity content of the raw material gas) can be used for a long time without the need for regeneration. The dual-tower parallel structure of the secondary dryer extends the regeneration time of the dryer. The regeneration cycle can be set arbitrarily within 48 hours or run according to a customized program, ensuring energy efficiency and high-quality purified gas. The efficient adsorbent can be reused after regeneration within the equipment. It is suitable for major production sectors requiring a large amount of high-purity oxygen, such as semiconductors, optical fibers, and cathode ray tubes.
The fully automatic purification equipment features a touch panel for one-touch start and stop, making the operation simple and clear. The device has two working groups that alternate and cycle between each other. While one group works, the other group undergoes regeneration and cooling as standby. The reactor has a long-term temperature retention, and the drying group works at room temperature without the need for heating. The corresponding touch screen panel allows users to view the hardware composition of the equipment, operation instructions, observe and monitor the working status of the working group and regeneration group, working time, switching time, total operating time of the equipment, regeneration heating time, and alarm status.
The equipment operates according to a customized program, and the operation panel is equipped with selection control buttons. Users can independently choose the regeneration cycle to avoid resource waste. All data is collected on the control touch screen, and any abnormal pressure or temperature can trigger audio and visual alarms, prompting inspection. The PLC outputs a 485 protocol, enabling remote control connectivity.
The equipment adopts a split design, with the mechanical part of the open pipeline and the explosion-proof cabinet for electrical control. The on-site equipment power part is equipped with a sealed junction box, and the hard pipes are connected to the electrical control box. The regeneration purge gas is externally discharged to a relatively high outdoor location.
An air valve is installed at the cooling water inlet end, which automatically opens at the start of regeneration. The water consumption during regeneration is less than 0.1 m3/h.
1. Industrial air intake: The oxygen purifier takes in industrial air, which serves as the raw material gas for the purification process. This air contains various impurities, including nitrogen, carbon monoxide, carbon dioxide, water vapor, and dust.
2. Catalytic cooling: The first purification stage involves catalytic cooling. A catalyst is used to facilitate the cooling process, which helps condense and remove certain impurities from the air. This step aids in reducing the temperature and preparing the air for further purification.
3. Secondary adsorption: After catalytic cooling, the air enters the secondary adsorption stage. This stage involves the use of adsorbent materials, such as zeolite or other specialized materials, which have a high affinity for nitrogen and other gases. The adsorbent selectively adsorbs and removes nitrogen, carbon monoxide, carbon dioxide, and other unwanted gases from the air, allowing oxygen to pass through.
4. Precision filtration: Following the secondary adsorption, precision filtration takes place. Multiple filtration mechanisms, such as filters with specific micron ratings, are employed to remove fine particles, dust, and other contaminants from the air stream. This ensures that the oxygen produced is of high purity and free from particulate matter.
5. Oxygen output: At the end of the purification process, the oxygen purifier delivers high-purity oxygen. The nitrogen, carbon monoxide, carbon dioxide, water vapor, and dust have been effectively removed, leaving a concentrated supply of oxygen for the intended use.
The equipment's structure, including the use of airtight systems, catalysts, dual-tower dryers, and control systems, ensures efficient operation, longevity, and the ability to regenerate components as needed. The equipment is designed to provide a continuous supply of purified oxygen, allowing it to be used in various industries where high-purity oxygen is required.
Advantages of Oxygen Purifiers
1. Low requirement for raw material oxygen: Oxygen purifiers can effectively purify oxygen even when the raw material gas has a high content of impurities or hydrocarbons, up to 1000 ppm. This means that users can utilize inexpensive industrial oxygen as the source gas while still meeting the required purity standards. This flexibility allows for cost savings by using readily available and affordable industrial oxygen.
2. High activity catalyst and large adsorbent capacity: The catalyst used in the oxygen purifier has high activity, while the adsorbent has a large capacity. This combination results in a more efficient purification process, reducing the overall cost of operation. The high activity catalyst ensures effective removal of impurities, while the large adsorbent capacity extends the lifespan of the equipment and reduces the frequency of replacement, contributing to cost savings.
3. Catalytic regeneration for long-term use: The oxygen purifier operates on a catalytic regeneration principle, allowing for long-term use of the equipment. When the purifying capabilities diminish over time, the catalyst can be regenerated, restoring its effectiveness without the need for frequent replacements. This feature further enhances cost-effectiveness by prolonging the lifespan of the oxygen purifier.
4. Dual-mode operation for continuous supply: The oxygen purifier is designed with a dual-mode structure, enabling continuous gas supply. While one group is in operation, the other group can undergo regeneration as a backup. This simultaneous working and regeneration capability ensures a consistent supply of purified oxygen, as one unit can effectively replace two single-mode purifiers. This feature contributes to enhanced productivity and convenience.
5. Touchscreen control with adjustable cycles: The oxygen purifier is equipped with a touchscreen interface that allows for convenient control and monitoring. The system incorporates online detection of pressure, temperature, and other parameters. The working and regeneration cycles of the system can be adjusted based on the actual usage requirements, enabling users to optimize gas consumption and conserve resources. This adjustable feature provides flexibility and cost savings in terms of gas usage.
6. Automatic switching and built-in safety systems: The purification and regeneration processes of the equipment have automatic switching functions, eliminating the need for manual operation. This improves the stability and safety of the system, preventing user-induced contamination or operational errors. Additionally, the oxygen purifier is equipped with built-in alarm systems for monitoring parameters such as over-temperature, over-pressure, low cylinder pressure, and valve malfunctions. These safety systems ensure the equipment operates safely and reliably.
