Embodiment Construction
[0027] Below in conjunction with accompanying drawing and concrete example for further description:
[0028] Such as Figure 4 As shown, the blast furnace slag punching process of the present invention comprises the following steps in turn:
[0029] A. The slag separated by the skimmer flows to the slag nozzle through the slag ditch;
[0030] B. The slag discharged from the slag nozzle is mixed with the water sprayed from the punching box, and then discharged into the bottom of the slag pool through the slag flushing ditch and the water diversion pipe;
[0031] C. The pneumatic lift pump transports the slag water at the bottom of the slag pool to the hub type dehydrator for dehydration. The dehydrated slag is sent to the slag dump by the belt conveyor, and the water flowing out of the dehydrator is transported to the The bottom of the slag water tank is transported to the bottom of the sedimentation tank through the diversion pipe during system maintenance; the overflow wate...
