Direct-dischargedchimneysmoke and rain treatment system

The invention provides a direct-dischargedchimneysmoke and rain treatment system. Thedirect-dischargedchimneysmoke and rain treatment systemuses a CFD diversion technology, a spoiler (2) is mounted onthe inner wall of the direct-dischargedchimney (1) to reduce the flow velocity of the smoke along the inner wall of the chimney so as to greatly reduce condensate water formed by the smoke on the inner wall of the chimney; acatch basin(3) is arranged on the inner wall of the direct-dischargedchimney (1), a drainage hole (4) is formed in the position of the catch basin(3) to drain the condensate water in the catch basinto the outside of the chimney for concentrated discharge; this way, forming of a small amount of condensate wateron the inner wall of the chimney is prevented from forming a chimney rain due to reentrainment, meanwhilethe structure is simple, resistance is low, and running cost is low. 本发明提供一种直排烟囱烟雨治理系统，其利用CFD导流技术，在直排烟囱(1)内壁上安装扰流板(2)，降低沿烟囱内壁的烟气流速，从而大幅度减小烟气在烟囱内壁形成的冷凝水；其在直排烟囱(1)内壁上设置集水槽(3)，并在集水槽(3)处设置
