Title:
METHOD AND ITS DEVICE FOR TREATING ASH MELTING FURNACE GRANULATION WATER
Document Type and Number:
Japanese Patent JP2007120842
Kind Code:
A
Abstract:

To provide a method for treating granulation water without enlarging waste water treatment equipment since waste water treatment equipment is not used, without raising salt concentration of recycled water since the granulation water is not recycled, and without lowering combustion energy.

The granulation water being slag cooling water is treated by carrying out particle size separation via a sedimentation tank, and spraying it on a temperature reducing tower or a melting temperature reducing tower of an incinerator to evaporate it. By carrying out particle size separation and removal of particles with a particle diameter of 0.01mm or more in the sedimentation tank, blocking of a nozzle carrying out spraying to the temperature reducing tower is prevented.
