According to the anti-impact device and method for the blow-down pipeline, a buffer device is arranged at the blow-down manifold blind end of a blow-down manifold body, blow-down branch lines are arranged on the side wall of the blow-down manifold body, and an included angle is formed between the blow-down branch lines and the blow-down manifold body. The length of the buffer device in the initial state is smaller than the depth from the pipe opening, connected with the emptying manifold body, of the emptying branch line to the blind end of the emptying manifold, during emptying, emptying air is sprayed into the outside of the front end face of the buffer device in the emptying manifold body through the emptying branch line, and the end of the buffer device makes contact with the blind end of the emptying manifold. The buffer device forms a low pushing effect after emptying air sprayed out of the branch line is emptied, the buffer device is pushed to reversely push the emptying air into the torch end of the e
