Abstract
The utility model discloses an air mixture gas sound pulse detonation tube. The air mixture gas sound pulse detonation tube comprises a straight tube with one end closed, a turbulator, an ejector and a sparkling plug. The turbulator is fixedly arranged on the inner wall of the straight tube, the sparkling plug and the ejector are arranged on the bottom of the straight tube or the tube wall close to the bottom of the straight tube, the straight tube is round or square or polygonal, the turbulator is an annular object, the number of the turbulator is 1-10, the blockage coefficient on airflow is 0.1-0.8, and the gaps among the turbulators are 0.5D-10D. According to the air mixture gas sound pulse detonation tube, air is used as oxidant, multiple air fuels can be used, the turbulators in the straight tube are used for generating turbulence, the turbulence enables combustible gas mixture to be changed into detonation quickly from deflagration, and high-temperature and high-pressure gas generated in the detonation is discharged from an opening end of the straight tube in hypersonic speed so as to generate pulse sound wave. High detonation speed values and decibel values can be obtained without use of reducing barrels and pure oxygen, heavy oxygen cylinders are not needed, use is convenient, manufacturing and use cost is reduced greatly, and safety is good.
Description
Technical field
The utility model relates to a kind of detonation tube, and particularly a kind of sky mixes combustion gas ping detonation tube.
Background technology
At present, folk festival mostly is purity oxygen and fuel gas mixed firing with salvo and firecrackers machine, it is pulsed sound that blast produces explosive sound, purity oxygen reservoir vessel heaviness, transportation trouble, the remote mountain areas is difficult to buy, though the airport bird scaring big gun of external import can be without purity oxygen but will be used the reducing gun tube, and sound is too overcast, the complicated cost height of reducing gun tube manufacturing is not suitable for agricultural and uses.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of sky simple in structure, that cost is low, safe and reliable to mix combustion gas ping detonation tube.
The technical scheme that the utility model addresses the above problem is: a kind of sky mixes combustion gas ping detonation tube, the straight tube, turbulator, injector and the spark plug that comprise end sealing, it is characterized in that: described turbulator is packed on the inwall of straight tube, and spark plug and injector are installed on the bottom or the close tube wall of bottom of straight tube.
Described straight tube is circular, square or polygon.
Described turbulator is the ring-type object, is installed on the inwall of straight tube, and its quantity is 1 ~ 10, is 0.1 ~ 0.8 to the coefficient that stops of air-flow.
Be spaced apart 0.5D ~ 10D between described turbulator and the turbulator.
The beneficial effects of the utility model are: the utility model directly uses airborne oxygen as oxidant, can use multiple fuel gas to be fuel, combustion mixture utilizes the turbulator turbulization in the straight tube, it is pinking from the detonation fast transition that turbulent flow makes combustion mixture, the high temperature and high pressure gas that pinking produces is discharged and the generation pulsed sound from straight tube openend hypersonic speed, need not to use the reducing gun tube just can obtain higher explosion velocity and decibel value, and need not use heavy oxygen cylinder, easy to use, manufacturing cost and use cost all significantly reduces, and security is better.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the utility model comprises straight tube 1, injector 2, spark plug 3 and the turbulator 4 of end sealing, the ring-type object of perforate centered by the described turbulator 4, be arranged on the inwall of straight tube 1, the quantity of turbulator 4 is 4, is 0.4 to the coefficient that stops of air-flow, being spaced apart between 0.5D ~ 10D between two turbulators 4, be 4D in the present embodiment, D is the equivalent diameter of straight tube 1, and spark plug 3 and injector 2 are installed on the bottom of straight tube 1 or the tube wall in the 2D scope of bottom.
Operation principle of the present utility model is as follows: air is mixed in the straight tube of end sealing with fuel gas under the ejector action of fuel gas, air inlet finishes back spark plug high-voltage spark and lights combustion mixture, gaseous mixture rapid expanding after lighting is advanced to the straight tube openend through turbulator, when the turbulator because the inhibition of turbulator and turbulization, the positive feedback effect that turbulent flow is strong has been accelerated the speed of chemical reaction, make that combustion mixture is pinking from the detonation fast transition, the high temperature and high pressure gas that pinking produces is discharged and the generation pulsed sound from straight tube openend hypersonic speed.
