Soot blower for tail flue of boiler

Abstract

The utility model relates to the technical field of boiler soot cleaning, and discloses a soot blower for a tail flue of a boiler, which comprises a support frame and a sound wave generator fixedly mounted at the upper end of the support frame, one end of a cleaning pipeline is in threaded connection with a protection component, and when soot blowing treatment is carried out on the tail flue of the boiler, the sound wave generator is in threaded connection with the protection component. The cleaning pipeline drives the sound wave output ports and the cleaning brush to be inserted into the inner cavity of the flue, then the sound wave generator is started, sound waves enter the inner cavity of the cleaning pipeline through the sound wave transmission pipe and are transmitted out through the multiple sound wave output ports formed in the two sides of the inner wall of the cleaning pipeline, and therefore soot blowing treatment is conducted on the inner wall of the flue. After dust attached to the interior of the flue is blown off, the dust directly falls on the outer wall of the hollow circular ring net and is shielded by the hollow circular ring net, so that the influence on the sound wave transmission pipe is reduced, and meanwhile, when the dust falls into an inner cavity of the hollow circular ring net, due to the fact that the intercepting net is arranged at one end of the sound wave transmission pipe, the falling dust can be intercepted again.

The sound waves generated by the sound wave generator are transmitted to the first amplifier through the sound wave transmission pipeline, and the sound waves are amplified by the first amplifier into the flue body. The energy of the sound waves can be propagated, so the sound wave energy can be propagated to the inner wall of the flue body, reduce the condensation of dust particles, and make the dust particles in a suspended and fluidized state, so that the flue gas can carry them away, and the soot blowing efficiency of the flue body is effectively improved.
