Air separation equipment for alumina activated alumina driers Alumina Alumina cold and dry air compressor alumina desiccant activated alumina is mainly used for drying liquids and gases. Although to some extent, can absorb all the molecules, but will give priority to absorbing molecules have strong polar. Activated alumina desiccant common sizes are ball 3-5mm, 4-6mm-5-7mm. Activated Alumina ball in the petrochemical, fertilizer industry, widely used as a catalyst, a catalyst support. Modern water purification and adsorption properties of activated alumina, which is used as a desiccant of gas and liquid, gas purification adsorbent, drinking water fluoride removal agent, industrial effluent color and odor elimination of agents. Air separation unit dedicated activated alumina drying agents use microporous material itself held to capillary adsorption of water molecules in the air, while relying on relief desorption and adsorption dryers come off waste heat to heat up the water adsorbed by the desiccant. Activated alumina life is different according to the intake air temperature is generally about two years, according to the dryer after the filter to determine the need for a desiccant. If the filter drain, you need to immediately put on activated alumina desiccant can also be based desiccant morphology, and end with the actual situation of gas to judge. Extended use of hazard desiccant, activated alumina desiccant loss of activity can not be drained of water, compressed air moisture content exceeding the standard. Affect air quality by producing equipment to work and products, activated alumina desiccant failure to live dusting impact Dryer life.
