Machine 1 is biaxial rneader.The pickling tank 2 and alkali immersion trough 9 are equipped with heater.
The technological process of the system is that solid slag is added by the waste residue import of beater and is beaten, and slurry enters acid
Immersion trough, tungsten, iron, manganese element are leached with hydrochloric acid, first-time filtrate and a filter residue are obtained by the first flame filter press, one
Secondary filtrate enters ion exchange column and carries out tungsten ion exchange, exchanges liquid and iron, manganese element are precipitated into sedimentation basin, stripping liquid
Reflect to obtain sodium tungstate solution into reactor and sodium hydroxide, enter back into evaporator and be evaporated crystallization；One time filter residue enters again
Enter alkali immersion trough and carry out alkali leaching, secondary filtrate and tin product are obtained after the separation of the second flame filter press；Secondary filtrate is contained
Hydroxyl, precipitated into stillpot, the clarified solution of stillpot is recycled to beater and recycled；In pickling tank and steaming
Hydrogen chloride gas caused by hair device can have tail gas absorber to be recycled.
The system can realize innoxious comprehensive utilization to ammonium paratungstate solid slag, not produce secondary residue liquid, using from
Son exchanges environmental protection, rate of recovery height.Tin, iron, manganese, tungsten can be reclaimed from waste residue, comprehensive recovery is high；Simultaneously to being produced in flow
Waste water and waste gas reclaimed, reach the effect of energy-saving and emission-reduction.
