[0002] Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. It has many channels with uniform pore sizes and neatly arranged holes in its structure. Molecular sieves of different pore sizes separate molecules of different sizes and shapes. Molecular sieves of different pore sizes are obtained according to the different molecular ratios of SiO2 and A12O3. Its models include: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10Z (calcium Z type), 13Z (sodium Z type), Y (sodium Y type), sodium mordenite type, etc. It has high adsorption capacity, strong selectivity, and high temperature resistance. It is widely used in organic chemical industry and petrochemical industry. It is also an excellent adsorbent for coal gas dehydration. It is also increasingly valued in waste gas purification. Molecular sieve oxygen generators generally adopt the pressurized adsorption and atmospheric desorption (HP) method, and two adsorption towers carry out the same cycle process respectively, so as to achieve continuous gas supply. The whole system is fully automatically controlled by a single chip microcomputer.
