Title:
HIGH TEMPERATURE EXHAUST GAS TREATMENT METHOD
Document Type and Number:
Japanese Patent JP2008256332
Kind Code:
A
Abstract:

To provide a high temperature exhaust gas treatment method enabling to cool high temperature exhaust gas down to a temperature allowing the treatment with a final dust collector without depositing and producing molten components or dust in the high temperature exhaust gas on the inner wall of a cooling tower.

The treatment method for the high temperature exhaust gas 5 comprises introducing the high temperature exhaust gas 5 including dust via flues into the cooling tower 2, and spraying cooling water to the high temperature exhaust gas 5 to be cooled in the cooling tower 2. In the planar view of the cooling tower 2, the high temperature exhaust gas 5 is introduced into the cooling tower 2 via the two-line flues 3a, 3b while holding equal flowing rate and amount therein. Axial center lines 3ac, 3bc of the two-line flues 3a, 3b are opposite and approximately perpendicular to an axial center line 2c extending in the vertical direction of the cooling tower 2.
