Air pre-heater for blowing soot through combination of sound waves and hot air

The utility model belongs to the technical field of air preheaters, and discloses a sound wave and hot air combined soot blowing air preheater, the air preheater can be divided into a tubular air preheater and a rotary air preheater, the rotary air preheater transfers heat in a regeneration mode, flue gas and air alternately flow through a heating surface of a rotor in the preheater to achieve heat transfer, and the rotary air preheater is used for blowing soot. According to the technical scheme, the air pre-heater comprises a heat exchange bin, a heat exchange rotor is arranged in the heat exchange bin, a driving motor is arranged at the top of the heat exchange bin, and an output shaft of the driving motor penetrates through the heat exchange bin and is rotationally connected with the heat exchange bin. According to the sound wave and hot air combined soot blowing air pre-heater, ammonium bisulfate can be softened or gasified in a high-strength variable-frequency sound wave and hot air combined mode, so tha
