Semi-automatic nitrogen purification equipment

This equipment uses industrial common gas as the feed gas, and obtains high-purity nitrogen by catalytic cooling, secondary adsorption and precision filtration to remove impurities, carbon monoxide, carbon dioxide, water vapor and dust.

The equipment has simple structure, good system air tightness, and the catalyst used can be used for a long time. The two-stage double-tower parallel structure dryer extends the regeneration time of the dryer. The regeneration set period is more than 48 hours, which is energy-saving and efficient, and ensures the quality of pure gas to the maximum extent. The high-efficiency adsorbent can be reused after regeneration in the product. It is applicable to major production departments such as semiconductors, optical fibers, picture tubes, etc. that require a large amount of high-purity nitrogen.

Since liquid nitrogen is not purified after vaporization, its oxygen content is generally between 2 ppm and 10 ppm. Sometimes the nitrogen provided by the gas supplier exceeds this range, but the customers using nitrogen do not know its quality, so it often affects the quality of the products. With the nitrogen purification device, regardless of the quality of nitrogen feed gas, as long as the nitrogen enters the vacuum furnace after being treated by the purification device, the purity is always constant. Generally, O2 is less than 1 ppm, and moisture is less than 2 ppm. Such stable nitrogen can guarantee the quality of the production object.
