The utility model comprises a fixed outer casing, a rotating rotor arranged in outer the casing, and an air cavity axially arranged in the rotor, wherein one end of the air cavity is sealed, the other end is communicated with an air source inlet opening, a nozzle communicated with the air cavity is radially arranged on the rotor, and a shock wave outlet opening is arranged on the outer casing and perpendicular to the rotor, and corresponds to the outlet opening of the nozzle. The nozzle can adopt a Laval nozzle, and the shock wave outlet opening can also adopt a Laval pipe. The utility model can utilize compressed air as energy sources, and also utilize steam as energy sources; firstly air current flows through the Laval pipe, a supersonic speed state can be achieved after the pressure is improved, and then a shock wave with high energy is formed. The utility model has the advantage that the soot blowing effect is better than the soot blowing effect of a common sound wave soot blower.
Description
Technical field:
The utility model relates to the grey dedusting field of blowing, and particularly a kind ofly adopts compressed air and steam to come boiler heating surface and flue as source of the gas and has the space of pollution to blow the device of grey dedusting.
Background technology:
Dust stratification is a ubiquitous problem in coal-fired and oil burning boiler heating surface and flue and the auxiliary equipment, and dust stratification causes the heating surface thermal resistance to increase, and for this reason, need regularly blow grey dedusting work.At present, the grey dedusting method that blows that adopts mainly contains machinery and blows three kinds of ashes, sonic soot blowing, pulse-combustion ash disposal, and adopt the sound wave form to blow the soot blower of ash, the general origin of using all is a compressed air, because sound wave energy quantitative limitation, its effective range is less, and is especially little to viscoplasticity ash effect, thereby dust removing effects is poor.And according to our understanding to shock wave, the energy relationship of shock wave and sound wave is: shock-wave attenuation is to a certain degree just becoming sound wave, so shock wave has bigger energy than sound wave.Therefore utilize shock-wave ash blowing, effect will be far superior to acoustic wave ash ejector.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of shock-wave ash blowing device, and it promptly can use compressed air as energy source, also can use steam.Utilize the utility model shock-wave ash blowing device to be shock wave to compressed air or steam-reforming, the pressure limit of source of the gas can at 0.2MPa ~ 3.8MPa.
The technical solution of the utility model is:
A kind of shock-wave ash blowing device, comprise and a rotor that rotates is arranged in a fixing shell, this shell, in this rotor, an air cavity arranged axially, one end sealing of this air cavity, the other end communicate with air source inlet, at the described epitrochanterian jet pipe that is connected with air cavity that radially has, be provided with the shock wave outlet perpendicular to rotor on the described shell, corresponding with described jet pipe.
Described jet pipe is a Rafael nozzle.
Described shock wave outlet is la farr pipe.
Described jet pipe is a plurality of, evenly distributes on epitrochanterian same or a plurality of circumference; Described shock wave outlet is one or more, and corresponding with the position of the epitrochanterian circumference in described jet pipe place.
Described jet pipe is 2 in epitrochanterian quantity, and the angle of the two is 180 °.
Operation principle of the present utility model is:
During use, rotation at a high speed under of the drive of cavity rotor at motor, steam or compressed air enter epitrochanterian air cavity from the air source inlet on the shell, air-flow in the air cavity is through epitrochanterian Rafael nozzle, be compressed earlier at this process air-flow, stream pressure sharply rises, and the air-flow expansion is accelerated to the supersonic speed state then, forms high-octane shock wave.When the shock wave on Rafael nozzle and shell outlet coincided, the gas generation pressure jump in the Rafael nozzle externally discharged, and formed strong shock wave blowing grey space, thereby reached the splendid grey effect of blowing.And Rafael nozzle is set to 2, and both angles are 180 °, is optimal frequency.
The utlity model has following characteristics:
1, available compressed air or steam are as energy source;
2, source of the gas pressure side is in extensive range, and 0.2MPa ~ 3.8MPa can be converted into shock wave;
3, blow the ash effective.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure:
The 1-shell;
The 2-rotor;
The 3-air cavity;
The 4-jet pipe;
The outlet of 5-shock wave;
The 6-air source inlet;
The specific embodiment:
See also Fig. 1, be the structural representation of the utility model shock-wave ash blowing device.As shown in the figure: the utility model comprises a rotor 2 that rotates in a fixing shell 1, this shell 1, in this rotor 2 air cavity 3 arranged axially, one end sealing, the other end of this air cavity 3 communicate with air source inlet 6, the jet pipe 4 that radially having on described rotor 2 is connected with air cavity 3, this jet pipe 4 is the Rafael nozzle that horn-like centre dwindles for two.Be provided with shock wave outlet 5 perpendicular to rotor 2 on the described shell 1, corresponding with the outlet of described Rafael nozzle 4.Described Rafael nozzle 4 is a plurality of, evenly distribute on the same or a plurality of circumference on the rotor 2, and the quantity of Rafael nozzle 4 on rotor 2 is set to 2, is the optimal frequency state when angle of the two is 180 °.Described shock wave outlet 5 is one or more, and corresponding with the position of the epitrochanterian circumference in described Rafael nozzle 4 places.
During use, rotation at a high speed under the drive of cavity rotor 2 at motor, the bleed pressure scope enters air cavity 3 in the rotor 2 at the steam of 0.2MPa ~ 3.8MPa or compressed air from the air source inlet 6 on the shell 1, air-flow in the air cavity 3 is through the Rafael nozzle 4 on the rotor 2, be compressed earlier at this process air-flow, stream pressure sharply rises, and the air-flow expansion is accelerated to the supersonic speed state then, forms high-octane shock wave.When Rafael nozzle 4 and shock wave outlet 5 on the shell 1 coincided, the gas generation pressure jumps in the Rafael nozzle 4 externally discharged, and formed strong shock wave blowing grey space, thereby reached the splendid grey effect of blowing.
The utility model can also export 5 with shock wave and be set to la farr pipe, thereby reaches same effect.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
