Filtering structure for pipeline gas

The utility model discloses a filtering structure for pipeline gas, and belongs to the technical field of filtering. The filtering structure for the pipeline gas comprises a first flat plate and a second flat plate which are parallel to each other and are arranged up and down, the first flat plate and the second flat plate have the same structure; two filter screens and two filter bodies are fixedbetween the top surface of the first flat plate and the bottom surface of the second flat plate; the two filter bodies are arranged on the sides, far away from each other, of the two filter screens;the two filter screens and the two filter bodies are symmetrically arranged about the connecting line of the center line of the first side surface of the first flat plate and the center line of the third side surface of the first flat plate; the horizontal distance between the two filter screens and the horizontal distance between the two filter bodies are gradually reduced from the first side surface of the first flat pla
