Semi automatic nitrogen purification equipment

This equipment uses industrial common gas as raw material gas, which is subjected to catalytic cooling, secondary adsorption, and precision filtration to remove impurities, carbon monoxide, carbon dioxide, water vapor, and dust, and obtain high-purity nitrogen gas.

This device has a simple structure, good system airtightness, and the catalyst used can be used for a long time. The two-stage double tower parallel structure of the dryer extends the regeneration time of the dryer, and the regeneration setting cycle is greater than 48 hours, which is energy-saving and efficient, and maximizes the quality of pure gas. The high-efficiency adsorbent can be reused after regeneration in the product. Suitable for major production sectors such as semiconductors, optical fibers, and cathode ray tubes that require a large amount of high-purity nitrogen gas.

Due to the lack of purification treatment after vaporization of liquid nitrogen, its oxygen content is generally between 2ppm and 10ppm. Sometimes gas suppliers provide nitrogen beyond this range, but customers who use nitrogen are unaware of its quality, which often affects the quality of the produced products. With the nitrogen purification device, regardless of the quality of the nitrogen raw gas, as long as it is processed by the purification device, the purity of the nitrogen entering the vacuum furnace remains constant. Generally, O2<1ppm and moisture<2ppm ensure the quality of the produced object with stable nitrogen gas.
