Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the utility model provides a technical scheme of a sampling pipeline self-cleaning device of a VOCs online monitoring system: the utility model provides a VOCs on-line monitoring system sampling pipeline is from cleaning device, is including the pivot 2 that is located 1 axis department of body, the vertical setting of body 1, and the upper and lower extreme of pivot 2 all rotates and is connected with horizontal pole 21, and horizontal pole 21 fixes on the inner chamber wall of body 1.
