Abstract
The utility model provides a rotary type shock wave nozzle, which comprises a shock wave generator, a bent pipe and a rotary nozzle. The shock wave generator, the bent pipe and the rotary nozzle are sequentially communicated with each other. One end of the rotary nozzle extends into a furnace wall, while the other end of the rotary nozzle is communicated with the shock wave generator via the bent pipe. The outside of the rotary nozzle is in power connection with a motor. The part of the rotary nozzle, which is close to the outer side of the furnace wall, is provided with a reinforced pipe. The outer side of the furnace wall is provided with a sealed pipe positioned corresponding to the reinforced pipe. Sealing fillings are filled between the reinforced pipe and the sealed pipe. The bent pipe and the rotary nozzle are connected with each other via a pair of stuffing boxes. The stuffing boxes are filled with packing. The rotary nozzle is also provided with a flange for compressing the packing in the stuffing boxes.
