Horizontal separator solid liquid centrfuga industrial hazardous waste disposal treatment
Hazardous waste treatment process
Gasification melting process is adopted. The system comprises feeding and preparing device + gasifier + secondary combustion chamber + residual heat exchanger (SNCR) + chiller + bag dust remover + alkali eluting sulfur tower + wet electrostatic precipitator + flue gas heat exchanger +flue gas burner+low temperature SCR + induced draft fan + chimney.
Compared with conventional incineration, the gasification and melting technology is completely harmless and remarkable in capacity reduction, and recovers energy and by-products.

Applications
Solid-liquid separation realized by using a high-efficiency LW series two-phase centrifuge can reduce the liquid content of the slag phase, facilitate transportation, and increase the combustion heat value.
Separation performance:
The water content of the slag phase after centrifugation can be ≤55, and its total volume is reduced by over 80% compared to that before separation;
The solid content of the liquid phase after separation can reach ≤0.1~0.2%;
