Activated alumina calciner
With fluidized roasting furnace, aluminum hydroxide, first will wet into DE dryer, again into fluidized baking furnace, spray into the fuel into alumina, after roasting granulation, preserve one's health, activation, classification, namely after the final product for. Fluidized roasting furnace system, which can make full use of burning waste gas and materials scattered the quantity of heat of the cooling, to preheat the cold and into the burning gas and air, system for material are both in the fluidized state and gas heat, high thermal efficiency, low heat consumption, only for turning the kiln device of 60% ~ 70%. Dynamic hydrocyclone calcined furnace using natural gas (oil, blast furnace gas) for heating fuel, choose natural gas combustion, straight, heating furnace of fire to calcining temperature. Measurement and feeder will aluminum hydroxide dry powder into the furnace, and produce to the high temperature of gas-solid mixing gas, heat transfer, mass transfer and rapid rise rapidly spinning, that is, 10 seconds calcined finish. Gas-solid mixing gas into the combination of gas-solid separation, after a whirlwind, the metakaolin products again into the fluidized bed after cooling for packaging, and after the heat source for calcination tail gas enters the dry containers, will contain wet aluminum hydroxide materials into powder dry, dry exhaust into level 1, level 2 together pre-heater, in into the pulse bag is gas-solid separation, purification of the exhaust is composed of high voltage induced draft fan after derivations, aluminum hydroxide dry powder calcined furnace calcining alumina into a finished product. After granulation, preserve one's health, activation, classification and a series of procedures for the final product that activated alumina.
