Plant exhaust structure

The utility model discloses a workshop exhaust structure, relates to the technical field of workshop ventilation systems, and solves the problems that the position of a pipeline exhaust device is fixed, and when machines at different positions operate for production, the exhaust device does not completely correspond to the positions of the operating machines, so that the exhaust efficiency of the exhaust device is not high. The device comprises an exhaust hood arranged in a plant, a fan is connected to the exhaust hood, an air pipe extending to the outside of the plant is connected to the end, away from the exhaust hood, of the fan, an opening allowing the air pipe to extend to the outside of the plant is formed in the position, corresponding to the air pipe, of the plant, and the air pipe drives the exhaust hood to swing in the horizontal direction. And the air pipe is connected with a fixing piece for fixing the air pipe and a plant. The exhaust device can achieve a better exhaust effect. 本申请公开了一种厂房排风结构，涉及厂
