On March 3rd, 2004, the Chinese patent ZL 03233622.5 of bulletin disclosed a kind of gas shock wave generating means, it is characterized in that: comprise single-piece piston group, annular seal space, shock tube, median septum, the piston of single-piece piston group has unequal sealing cross-sectional area, a piston of single-piece piston group moves at annular seal space, median septum separates annular seal space and sealing energy-storing chamber, a piston of single-piece piston group can move along shock tube, and shock tube links to each other with the sealing energy-storing chamber at an end of sealing energy-storing chamber.This gas shock wave generating means can be converted into the part energy of gases at high pressure the kinetic energy of piston high-speed motion between high and low gas, give piston through after the segment distance motion at full speed, form the instantaneous action of opening the door of high speed of piston, be that high and low pressure gas contacts suddenly, form the initial compression ripple, develop into shock wave again.But the structure more complicated of this device, the energy of gases at high pressure can only partly be converted into shock wave, and the shock velocity of generation and equivalent are not high, and the operating distance of shock wave is shorter.
The utility model content
The purpose of this utility model provides air a kind of simple in structure, easy to operate or steam shock generator, can produce the shock wave of speed height, operating distance length.
The technical solution used in the present invention is as follows:
Air or steam shock generator, comprise energy-storing chamber that sealing is provided with and the air inlet pipe that is communicated with energy-storing chamber, an end that it is characterized in that energy-storing chamber is provided with the tubular cylinder, in the tubular cylinder piston is set, one end of tubular cylinder is provided with air inlet, the other end communicates with energy-storing chamber, the shock wave playpipe pass energy-storing chamber the other end and and the setting of tubular cylinder coaxial, distance between the air inlet end face of shock wave playpipe and tubular cylinder end face is less than the thickness of piston, and the air inlet of shock wave playpipe can be by piston seal.
One end of described piston is provided with medial recess, and the air inlet end of an end of depression towards cylinder is set.
Described energy-storing chamber is that two ends are oval-shaped cylinder barrel shaped chamber.
Described tubular cylinder and shock wave playpipe are separately positioned on two oval terminations of annular seal space and pass this ellipse termination respectively.
On the described cylinder intake pipe commutation air valve is set.
The air inlet pipe that is communicated with energy-storing chamber is pressure-air or high steam air inlet pipe, and air-supplying valve is set on the air inlet pipe.
The operation principle of this air or steam shock generator is: open the valve of cylinder intake pipe, charged pressure gas in cylinder, gas promote piston and move to the air inlet side of shock wave playpipe, seal the air inlet of shock wave playpipe at last.Working media pressure-air or steam enter air storing cavity by the air inlet pipe that is communicated with energy-storing chamber, form certain high pressure in air storing cavity.By the valve venting of cylinder air inlet, the gas in the cylinder is discharged, and piston is subjected to the very fast travelling backwards of the effect of air storing cavity pressure, and the Compressed Gas in the air storing cavity ejected by the shock wave playpipe in the moment of several microseconds, formed shock wave.
This air or steam shock generator architecture are simple, utilize cheap energy medium, low and the clean environment firendly of energy consumption, can produce the shock wave of speed up to 2 Mach, operating distance reaches 4 meters, can satisfy the various deashing operation needs that need ash removing equipment, this shock wave generator can mobile working, overcome acoustic wave soot blower and gas impulse dust remover and can only be fixed on the defective that use a position, this air or steam shock generator can access sufficient safety assurance in addition, the equipment deashing operation of especially various petrochemical industry, oil plant.
