Abstract

PURPOSE: To facilitate operation and raise thermal efficiency by performing pre- heat drying and burn melting of waste active sludge continuously with arc heat.
CONSTITUTION: The waste active sludge is charged from the top 10 of a furnace and is pre-heated and dried in the upper part 5 of the furnace. After that, is it melted with arc heat and, dropping down through the furnace gradually, is burnt in the intermediate zone 6 of the furnace. The melting of the burnt sludge begins in a high-temperature area 7 around the arc and the melted sludge drips down to the bottom of the furnace. In the course of this process, heavy metal compound is mostly reduced to be of metal phase by carbon monoxide or the fixed carbon produced through carbonization of the sludge or the like in the furnace. Melted slag 8 is put out from a tap 3 when it reaches a certain quantity, while melted metal 9 is also put out from another tap 4.
