[0018] The ignition device 4 is ingeniously arranged inside the high-pressure chamber 7, and its main function is to generate ignition in the high-pressure chamber 7 to initiate rapid combustion of the gas in the chamber, thereby forming a high-pressure shock wave.The control unit 5 is closely connected to the ignition device 4 and is responsible for accurately controlling the ignition timing and frequency of the ignition device 4 to ensure the stable generation of pulse shock waves, thereby improving the soot blowing effect.

[0019] To ensure that the tank body 1 can withstand the huge pressure generated by the high-pressure shock wave, the material is selected to be high-strength steel.The design of the ignition device 4 is also ingenious, including an electric spark plug and a high-voltage cable.The electric spark plug is placed in the high-pressure chamber 7, and the high-voltage cable is responsible for transmitting the ignition signal generated by the control unit 5 to the electric spark plug to ensure the smooth progress of the ignition process.
