This equipment utilizes industrial air as the feed gas and employs catalytic cooling, secondary adsorption, and precise filtration to remove impurities, carbon monoxide, carbon dioxide, water vapor, and dust, thereby obtaining high-purity oxygen.
The equipment has a simple structure and excellent system airtightness. The catalyst used (adjustable based on impurity content in the feed gas) requires no regeneration over long periods. The dual-tower parallel structure of the drying unit extends the regeneration time, allowing for a regeneration cycle of more than 48 hours, set arbitrarily or based on a custom program. This energy-efficient design ensures optimal purity of the gas, while the highly efficient adsorbent can be reused after regeneration. It is suitable for major production sectors requiring large quantities of high-purity oxygen, such as semiconductors, optical fibers, and cathode-ray tubes.
The fully automatic purification equipment features a touch panel with one-touch start and stop operation, making it easy to use. The device consists of two working groups that alternate their operation, ensuring continuous cycling. While one group works, the other undergoes regeneration and cooling. The reactor has a long-term temperature holding period, and the drying unit operates at room temperature without requiring heating. The touch screen on the corresponding panel allows for viewing the hardware composition, operational instructions, observation, monitoring of the working group's status, regeneration group's regeneration status, working group's operation time, switching time, total equipment operating time, regeneration heating time, and alarm status.
The equipment operates according to a custom program, and the control panel is equipped with selection control buttons that allow for independent selection of the regeneration cycle, eliminating resource wastage. All data is collected on the control touch screen, and alarms are generated for abnormal pressures and temperatures, prompting inspection. The PLC outputs a 485 protocol for remote control connectivity.
The equipment is designed in a split-type configuration, with the mechanical part of the open pipeline and the explosion-proof cabinet for electrical control. The on-site equipment power section is equipped with a sealed junction box, and the rigid pipes are connected to the electrical control box. The regeneration purge gas is discharged outdoors at a higher level.
An air valve is installed at the cooling water inlet to automatically open during regeneration. The water consumption during regeneration is less than 0.1 m3/h.
