Through-wall sealing mechanism for air shock wave soot blower

The utility model relates to the technical field of air shock wave soot blowers, in particular to a through-wall sealing mechanism for an air shock wave soot blower, which comprises an air shock wave soot blower through-wall pipe and a boiler wall for installing the air shock wave soot blower through-wall pipe, and the air shock wave soot blower through-wall pipe is sequentially provided with a first pipeline and a second pipeline from inside to outside. A sealing layer is arranged on the side, away from the boiler wall, of the second pipeline, a rubber pad is arranged on the side, away from the second pipeline, of the sealing layer, and a plurality of reset springs are arranged between the rubber pad and the first pipeline at equal intervals. Vibration is buffered through cooperation of a rubber pad and a reset spring, impact of stress on the wall is reduced, and a limiting strip is additionally arranged outside the through-wall pipe of the air shock wave soot blower and matched with a limiting groove in the
