This.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of complete alternation nano aluminium oxide production line, including dewatered drying line, disintegrating machine, thermal decomposition line, ultra-fine comminuting system and
Mixing tank, the dewatered drying line, disintegrating machine, thermal decomposition line, ultra-fine comminuting system are sequentially connected, and heat is provided with dewatered drying line
Switch, thermal decomposition line are connected by discharge duct with heat-exchange device, and heat-exchange device is connected to mixed by outlet pipe
In batch can, mixing tank is connected with dewatered drying line, and the mixing tank is connected with feed pump.
Further, the disintegrating machine uses corundum ceramic jaw crusher.
Further, operating temperature is 1000~1300 degree in the thermal decomposition line.
Further, the ultra-fine comminuting system includes air compressor machine, air accumulator, cooling driers, crushing main frame, whirlwind discharging
Device, dust collector and air-introduced machine are connected in turn.
Further, the crushing main frame uses fluidized bed opposed jet mill machine.
The present invention has the advantages that：The product of thermal decomposition line has ammonia, sulfur trioxide, water vapor gas, gas
Residual temperature reaches 800 degree, the heat-exchange device entered by discharge duct in dewatered drying line, waste heat can be made full use of to be dried for dehydration
Used in main line, the gaseous product after heat exchange, which is sent into mixing tank, regenerates Exsiccated Ammonium Alum crystalline substance with ammonium sulfate, reacting aluminum sulfate
Body so that the entire production line forms complete alternation, improves formation efficiency, and takes full advantage of the waste heat in generating process, without useless
Gurry is discharged, environmentally safe, and cost has been saved for enterprise.
