A control system and method for dry centrifugal granulation of liquid slag are provided. The control system includes a granulator cold-air control unit and a feeding unit. The granulator cold-air control unit includes a granulator, a rotating shaft, a motor, and a cold-air supply unit. The granulator is fixed to the motor; the cold-air supply unit includes a shaft cooling air channel and an annular cooling air channel; the shaft cooling air channel consists of an inner duct sleeve and a shaft sleeve; the annular cooling air channel consists of the inner duct sleeve and an outer duct sleeve arranged at periphery of the inner duct sleeve, which have different external diameters; the feeding unit includes a slag dropping pipe arranged above the granulator; a sliding gate is arranged at a lower section of the slag dropping pipe, and an accident diversion spout is equipped.

Control system and method for dry centrifugal granulation of liquid slag

A second-level liquid slag cache system with flow and temperature monitoring and control functions is disclosed. A slag inlet is located at an upper portion of the slag ladle casing; at least one slag discharging unit is located at a side of a lower portion of the slag ladle casing; one slag discharging unit is corresponding to one stopper; the stopper includes a stopper head, a stopper rod and a stopper control mechanism; the stopper control mechanism is configured to control the flow area between the stopper head and the sizing nozzle; a sealing cover is disposed outside the sizing nozzle; a slag control tube is installed at a bottom of the sealing cover. The present invention is able to achieve liquid slag buffer, flow control and heat compensation, so as to allow liquid slag to continuously stably perform a subsequent granulation process.

Second-level liquid slag cache system with flow and temperature monitoring and control functions

A liquid slag granulating system includes a granulator (), a granulator connecting part and a granulator drive part. The granulator () is disc-shaped or cup-shaped, and a diversion cone is arranged at a center of the granulator (). The granulator drive part drives the granulator to rotate, thus granulating liquid slag. The system further includes an air supply part.
