Abstract

本发明脱硝烟道反应器墙板,包括墙板本体、支撑骨架,支撑骨架位于墙板本体的外侧。支撑骨架位于墙板本体的外侧,也即把角钢、H型钢制作的支撑骨架朝烟道的外部,墙板本体位于烟道的内侧,朝外的由角钢、H型钢等型材制作的支撑骨架可以用外保温材料将其包好,既不影响外观美丽,也不妨碍正常使用的条件,而且可以降低生产成本,节约工时。

Description

脱硝烟道反应器墙板
技术领域
本发明涉及一种气体脱硝装置,尤其是涉及一种脱硝烟道。
背景技术
NOx(NO和NO2)是大气的主要污染物之一,选择性催化还原法(SCR),就是在一定温度条件下(280~400℃),借助于催化剂的帮助,用氨(NH3)来还原NOx的过程。脱硝烟道反应器墙板是维护和承载陶瓷催化剂及设备的结构,防止烟气泄漏。现在制作脱硝烟道反应器墙板时,一般是把由角钢、H型钢等型材制作的支撑骨架安装在墙板本体的内侧,即烟道的内部,把墙板本体安装在支撑骨架的外侧,每段墙板本体通过型材焊接在一起,焊缝之间容易产生间隙,为了防止烟气泄漏,在内部加装若干用簿钢板(如δ3)钢板做的密封条,安装时不方便,而且也浪费时间、浪费材料,增加了不必要的生产成本。
发明内容
本发明的目的是提供一种脱硝烟道反应器墙板,不仅制作安装方便,而且节约材料、降低工时。
为解决上述技术问题,本发明脱硝烟道反应器墙板,包括墙板本体、支撑骨架,每侧的墙板本体为一体结构,支撑骨架位于墙板本体的外侧。
支撑骨架位于墙板本体的外侧,也即把角钢、H型钢制作的支撑骨架朝烟道的外部,墙板本体位于烟道的内侧,这样每侧的墙板本体为一体结构,可以减少使用簿形钢板制作的密封条,还可以减少异形的密封条,朝外的由角钢、H型钢等型材制作的支撑骨架可以用外保温材料将其包好,既不影响外观美丽,也不妨碍正常使用的条件,而且可以降低生产成本,节约工时。
附图说明
下面结合附图对本发明作进一步详细的说明。
图1为本发明脱硝烟道反应器墙板结构示意图。
图2为现有技术脱硝烟道反应器墙板结构示意图。
图中1为墙板本体、2、3为型材。
具体实施方式
如图1所示,本发明脱硝烟道反应器墙板包括墙板本体1、由型材2和型材3组成的支撑骨架,墙板本体1为钢板,型材2为H型钢,型材3为角钢。支撑骨架位于墙板本体1的外侧,也即把角钢、H型钢制作的支撑骨架朝烟道的外部,墙板本体1位于烟道的内侧,墙板本体1与型材质、型材3焊接。朝外的由角钢、H型钢等型材制作的支撑骨架可以用外保温材料将其包好,既不影响外观美丽,也不妨碍正常使用的条件,而且可以降低生产成本,节约工时。
