ASU sieve apparatus

Compare activated alumina and molecular sieve adsorption of water features seen: Activated alumina for higher air moisture adsorption capacity is relatively large, but with reduced air moisture adsorption capacity drops quickly. The molecular sieve even at very low water content, the same has strong water absorption. Also, aluminum plastic desorption water easily, can reduce the regeneration temperature; it heats of adsorption of water smaller than the molecular sieve, the air temperature rise is small, is conducive to the rear of the molecular sieve adsorption of CO2; and aluminum plastic also has acid resistance, molecular sieve can play a protective role. Based on these characteristics, some purifiers structure with a double bed, air purifier into the I = I side, put a layer of activated alumina. It is the first most of the water contained in the air cleared, and the molecular sieve is mainly used to remove carbon dioxide, acetylene and other hydrocarbons. Using double adsorption bed, you can extend the use of purification time. Carrying activated alumina - Zeolite bunk bed test results: purifier effective working time extension of 25% to 30%.
