Research on overflow concentration control method of concentrator in coal preparation plant
The monitoring and control method of overflow concentration in concentrator is one of the keys to realize intelligent coal preparation in coal preparation plant,aiming at the problem that the over-flow concentration monitoring and control method only using sensor will lead to the lag of flocculant reg-ulation.Aiming at this problem,a concentrator automatic dosing system is built,which uses the moni-toring and control method combined with BP neural network and fuzzy Active Disturbance Rejection Control(ADRC)to realize the stability control of the overflow concentration of the concentrator.The concentration reaction should not be directly affected by the amount of flocculant added,thus affecting the flocculation settling effect.Through simulation comparison,the proposed method has higher stability than the automatic dosing system using PID control,and can effectively deal with the lag problem of flocculant regulation.A new scheme is proposed for the overflow concentration control of concentrator in coal preparation plant.
