Problems solved by technology

Ammonia is an irritating gas, and the harmful gas cannot be purified to a certain extent, thus causing certain pollution to the environment after being discharged into the atmosphere
In the process of using aluminum ash for production in the prior art, there is still a problem that high alumina purity cannot be achieved, which affects the recovery efficiency of aluminum ash, which in turn affects the energy recovery rate

Abstract

The invention discloses a method for preparing aluminum oxide by using aluminum ash, and also provides equipment for preparing aluminum oxide by using the method. By adopting the system provided by the invention, the function of integrally processing aluminum ash into aluminum oxide is achieved, harmless discharge is ensured, the functionality and practicability are high, and the system can be widely applied to the technical field of aluminum oxide production.

Description

technical field [0001] The invention relates to the field of alumina production, in particular to a method and a system for harmlessly producing alumina by using aluminum ash. Background technique [0002] In the prior art, in the process of using aluminum ash to produce alumina, a certain amount of harmful gas will be produced. For example, aluminum ash is sprinkled with water, and AlN in it reacts with water to generate ammonia gas. The reaction is as follows: AlN+3H2O =Al(OH)3+NH3. Ammonia gas is an irritating gas, and the harmful gas cannot be purified to a certain extent, thus causing certain pollution to the environment after being discharged into the atmosphere. In the process of using aluminum ash for production in the prior art, there is still a problem that high alumina purity cannot be achieved, thereby affecting the recovery efficiency of aluminum ash, and then affecting the energy recovery rate. [0003] Therefore, a technology capable of solving the above-men...
