Light calcined magnesia suspension roaster ash treatment system and method
The invention discloses a light calcined magnesia suspension roaster ash treatment system and method, belonging to the field of light calcined magnesia roaster ash treatment devices. According to a light calcined magnesia suspension roaster ash treatment system, an outlet of conveying equipment is connected with an inlet of a blocking valve; an outlet of the blocking valve is connected with a heating medium inlet of a raw material drying unit through a current-carrying pipeline, and the raw material drying unit is sequentially connected with a raw material separation unit, a raw material preheating unit, a suspension roaster and a gas-solid separation unit; and ash-containing gas separated by the gas-solid separation unit returns back and is connected with the raw material preheating unit,the raw material separation unit, a roaster ash collection unit and the conveying equipment. According to the method, roaster ash returns to the heating medium inlet of the raw material drying unit and enters the raw material drying unit along with the heating medium to be mixed with normal-temperature raw materials. The method can improve the operation stability and roasting efficiency of the suspension roaster, reduce roasting temperature, lower energy consumption and improve product quality and yield.
