一种有效消除转角漩涡的烟道结构
摘要：
本实用新型的目的在于提供一种有效消除转角漩涡的烟道结构，设于SCR脱硝反应器上部斜切烟道与上游烟道的连接处，连接SCR脱硝反应器靠近上游烟道一侧的侧壁板及上游烟道底部的底板；包括：一圆弧形板；连接该底板及该圆弧形板的一端的一上游连接板，连接该侧壁板及该圆弧形板另一端的一下游连接板。该烟道结构不仅可以有效消除SCR反应器上部斜切烟道与上游烟道连接处的恶劣漩涡区，而且能够在一定程度上改善首层催化剂入口截面的速度分布均匀性。
摘要（英）：

An object of the utility model is to provide an effectively eliminate flue structure of corner swirl locates the cut sth. Askew junction of flue and upper reaches flue of SCR denitration reactor upper portion, connects SCR denitration reactor and is close to the lateral wall board of upper reaches flue one side and the bottom plate of upper reaches flue bottom, include: a circular arc shaped plate, connect an upper reaches connecting plate of the one end of this bottom plate and this circular arc shaped plate, connect a low reaches connecting plate of this lateral wall board and this circular arc shaped plate other end. The cut sth. Askew abominable swirl district of flue and upper reaches flue junction of SCR reactor upper portion not only can effectively be eliminated to this flue structure, can improve the speed spray deposition uniformity in first floor catalyst inlet cross -section to a certain extent moreover.
