3 working principle is the use of carbon molecular sieves, sieving editing features to achieve the separation of oxygen, nitrogen purpose. Shanghai zeolite manufacturers, macroporous and mesoporous molecular sieve adsorption of impurity gases when only play the role of the channel, the molecules are adsorbed transported to micro and sub-micro sieve plant in Shanghai, micro and sub-micro is really starting adsorption volume. As shown in FIG Shanghai molecular sieves, carbon molecular sieves comprise a large number of internal pores, the pores allow the kinetics of small molecules rapidly diffuse into the pores size zeolite Shanghai offer, while limiting the entry of large diameter molecules. Due to the different sizes of the gas molecules relative diffusion rate differences, components of the gas mixture can be effectively separated. 4, gas production time according to the diffusion rate of carbon molecular sieve for absorbing oxygen and nitrogen different, O2 adsorption reached equilibrium in a short time, this time, the amount of N2 adsorbed is small, a shorter time of gas, can effectively improve the carbon molecular sieve gas production rate, but also increases the frequency of cutting the door of the action, so the performance of cutting the door is also very important. Generally selective adsorption time of 30 to 120 seconds. Small high purity Nitrogen gas production is recommended to use a short time, a large low-density gas is recommended to use a long time.
