CATALYST MODULE STRUCTURE OF HIGH TEMPERATURE DENITRIFICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a catalyst module structure of a high temperature denitrification apparatus which can prevent buckling in the outer plate of a cylindrical unit in the catalyst module due to drastic temperature changes on initiating the process and which can prevent damages in the catalyst.

SOLUTION: The catalyst module 12 is constituted by attaching an outer plate 16 which can slide on thermal expansion to an outer frame 15 comprising assembled square steel tubes 13 and L-shape steels 14 to obtain a top panel, base panel and side pane 19 as outer frame panels, assembling the top panel, base panel and side panel 19 as outer frame panels to make a cylindrical unit 20 having openings in the front and rear faces, and filling the inside of the cylindrical unit 20 with a catalyst 21 by supporting the catalyst by the outer frames 15.
