Our company has a large number of oxygen generators. If you are interested, you can come and have a look. Not only that, in order to reflect the diversification of our business, we also have SMT Cleaning Machine, PCB Cleaning Machine, PCB Separator, Reflow / Wave Soldering Machine, SMT Nozzle / Feeder.Next, I will introduce the classification of nitrogen generators.
1. Cryogenic Air Separation Nitrogen Generator:
Cryogenic Air Separation Nitrogen Generator is a traditional nitrogen production method with a history of several decades. Air is used as raw material, compressed and purified, and the air is liquefied into liquid air through heat exchange. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. The boiling point of liquid oxygen and liquid nitrogen is different (under 1 atmosphere, the boiling point of the former is -183 and the boiling point of the latter is -196), and nitrogen is separated by liquid-air rectification. Cryogenic batch Nitrogen Production Equipment is complex, covers a large area, high construction cost, one-time investment in equipment, high operating cost, slow gas production (12) 24h), high installation requirements, and long cycle. Comprehensive equipment, installation and construction of many factors, equipment below 3500Nm3/h, the investment scale of PSA devices of the same specification is 20% to 50% lower than that of cryogenic air separation devices. The cryogenic split nitrogen production device is suitable for large-scale industrial nitrogen production, but it is not economical for medium and small-scale nitrogen production.
2, molecular sieve nitrogen generator: uses air as raw material, carbon molecular sieve as adsorbent, adopts pressure swing adsorption principle, uses carbon molecular sieve to selectively adsorb oxygen and nitrogen to separate nitrogen and oxygen, commonly known as PSA nitrogen production. This method is a new type of nitrogen production technology that developed rapidly in the 1970s. Compared with the traditional nitrogen production method, the process is simple, the degree of automation is high, the gas production is fast (15~30 minutes), the energy consumption is low, the product purity can be adjusted according to user needs in a large range, the operation and maintenance are convenient, the operating cost is low, and the device Suitability
3, Membrane Air Separation Nitrogen Generator Using air as the raw material, under certain pressure conditions, oxygen and nitrogen and other gases with different properties are used to separate oxygen and nitrogen in the membrane at different permeation rates. Compared with other hydrogen production equipment, it has the advantages of simple structure, small size, no switching valve, less maintenance, fast gas production (3 minutes), and convenient capacity expansion. It is especially suitable for small users with a nitrogen purity of 98. On the other hand, When the nitrogen purity is above 98%, the price will be more than 15% higher than that of the PSA nitrogen machine of the same specification.
