Abstract
Disclosed is a combined heat exchange system of flash tank and preheater for laterite nickel ore leaching. The system comprises a high-pressure reactor, preheating towers, and flash tanks. The preheating tower is connected to the feed inlet of the high-pressure reactor. The flash tank is connected to the discharge outlet of the high-pressure reactor, and it is also connected to the preheating tower. Inside the flash tank, there is a pressure relief chamber and a buffering mechanism. The buffering mechanism comprises a buffering component and a connecting structure that are interconnected. In this disclosure, the buffering component of the pressure relief chamber is equipped with a central bulge and a buffering tank, materials falling from the pressure relief chamber can sequentially pass over the central bulge and slide from one end of the buffering tank to the other, then slide upwards out of the tank, achieving a buffering effect.
