Method and device for water quenching of yellow phosphorus furnace slag

The invention discloses a method and a device for water quenching of yellow phosphorus furnace slag. The method comprises the steps of water-quenching the molten phosphorus slag in a sluiceway by slag flushing water, and separating the phosphorus slag from the water through a dehydrator so as to achieve the aim of separating the quenched slag from the slag water. The method and the device have a good water-quenching effect and a high automation degree and can ensure a clean field environment and guarantee that vapor and harmful substances are orderly collected.
