[0002] The soot blowing devices currently on the market or have been installed in a large number of boiler tail flues generally use steam continuous soot blowing devices, sonic wave soot blowing devices, and shock wave soot blowing devices. Steam, due to the low working parameters, is easy to condense and stick to ash, which will lead to a large increase in smoke exhaust and heat loss of the boiler. At the same time, when the mechanical failure of the purging equipment itself occurs, if it is not discovered in time, it is easy to blow out the equipment. , causing leakage and causing shutdown of the furnace; the sound wave soot blowing device uses low-pressure compressed air to generate mechanical vibration energy, which resonates with the floating ash. Due to the low pressure, the soot blowing effect is unsatisfactory, but it is helpless for viscous dust; the shock wave The soot blower adopts the pressure wave generated by the deflagration of combustible gas. The pressure can reach up to 0.1MPa, and the soot blowing effect can meet the expectations. However, the working parameters of the medium are low, and the deflagration occurs outside the pulse tank. The working characteristics determine that its operating area is too small. The soot blowing blind area is too large, and it is easy to squib, resulting in too much equipment installation, which requires a considerable number of soot blowers and consumes a lot of flammable and explosive gases, usually hydrogen, acetylene, methane, gas, liquefied petroleum gas etc. At the same time, these bottled combustible gases are stored near the boiler for a long time, which is really a great safety hazard. Therefore, it is necessary to carry out technical upgrading or product replacement

[0003] The two fundamental problems to be solved by the soot blowing device are: one is the quality of the blowing medium; the other is the problem of rapid detonation
