Waste gas purification pipe

The waste gas purification pipe comprises a pipe body and a spraying system, the bottom of the inner wall of the pipe body is obliquely arranged in the axial direction, and the inner wall of the pipe body is covered with a negative ion coating for generating negative ions; the spraying system is installed on the pipe body and comprises a circulating pipeline and a sprayer arranged in the pipe body, the water inlet end of the circulating pipeline is communicated with the lower end of the bottom of the inner wall of the pipe body, and the water outlet end of the circulating pipeline is connected with the sprayer. According to the technology, a spraying system and negative ion purification are integrated in one waste gas purification pipe, the waste gas purification pipe can be a section in a smoke exhaust pipe system, space is not occupied, and the waste gas purification treatment effect is better. 本发明公开了一种废气净化管，其包括：管体和喷淋系统，管体的内壁底部沿轴向呈倾斜设置，在管体内壁覆有产生负离子的负离子涂层；喷淋系统安装于管体，喷淋系统包括循环管路、设置于管体内的喷淋器，循环管路的进水端连通于管体内壁底部的下端，
