DEVICE FOR FUSING INCINERATED ASH, COUPLED WITH ROTARY KILN INCINERATOR

摘要

PROBLEM TO BE SOLVED: To develop a device which minimizes the quantity of used coke as far as possible when performing the fusion treatment of incinerated ash discharged from an incinerator and can utilize scrapped plastic to 100% at maximum as a heat source in the rotary kiln type of incinerator. ;SOLUTION: For this fusion disposer, a fusion furnace 20 is coupled with a discharge port for incinerated ash produced from a rotary kiln type of furnace 10. Fusion furnace 20 is constituted in such a way as (a) to arrange a gas cracking chamber 22, where a certain space for thermally cracking scrapped plastic by introducing carrying air and staying slag fusion temporarily is made at its lower part; (b) to let an introduction port 23 for carrying air for carrying in the pieces of scrapped plastic front on one pat of that gas cracking chamber; and (c) to form a combustion fusion chamber 27, where a luster 26 for accelerating the rise of cracked gas and the drop of fused slug is arranged above in that gas cracking chamber, and also an air introduction port for accelerating the combustion with cracked gas fronts on it, at its upper part of that gas cracking chamber, and to lead incinerated ash into that combustion fusion chamber so as to fuse it.;COPYRIGHT: (C)2001,JPO
