Abstract
The utility model relates to a pulsing tank for gas shock-wave ash removal, which belongs to the technical field of gas shock-wave generating devices for the ash and dirt removal of industrial devices and comprises a tank body, a gas inlet and a shock-wave outlet. The utility model is characterized in that longitudinal grid plates which are arranged along the radial direction of the tank body are welded on the inner wall of the tank body, a plurality of annular hole plates which share the same center with the tank body are vertically welded with the longitudinal grid plates and the outer diameter of the annular hole plate is smaller than the inner diameter of the cross section of the tank body. The pulsing tank for gas shock-wave ash removal has the advantages of simple disturbance structure and no minus effect, can furthest utilize the energy of gas explosion and can finally generate a velocity which is four to eight times as fast as the sound velocity. When the valve of the shock-wave is 1.5Mpa, the ash removing effect is enhanced obviously and blocking ash in devices can also be thoroughly removed. The utility model can be used for removing ash and dirt at the heating faces of various industrial devices, such as boilers, etc.
Description
Technical field
The utility model belongs to the gas shock-wave generating means technical field that is used for the scale removal of industrial equipment deashing, relates in particular to the Impulsive tank that a kind of gas shock-wave deashing device uses.
Background technology
The gas shock-wave generating means is that the impact that utilizes the method that fires to produce involves action of high-speed airflow reaches ash disposal in boiler heating surface purpose.Fire differently with conventional combustion system, the pressure that fires generation constantly rises in Impulsive tank, and at the shock wave exit launching shock ripple of Impulsive tank, impacting intensity of wave and high velocity air flow velocity is the decisive factor of ash-removal effect.
In existing gas shock-wave dust remover, the inside of its Impulsive tank mostly is hollow structure and simple perturbations, the Chinese patent ZL 00209277.8 of bulletin provides a kind of weak explosion wave dust remover as May 16 calendar year 2001, this dust remover comprises the flame inlet tube, expand the flame section, the cylinder cavity, orifice plate, shock wave transmitting tube and shock wave emission port, 1～40 annular oriffice is housed in the weak explosion wave dust remover, the endoporus area of orifice plate is 0.2～1 with the ratio of the endoporus cross-sectional area of cylinder cavity, distance between adjacent two orifice plates is 0.2～10 times of orifice plate external diameter, and the tube wall of shock wave transmitting tube has 1～50 hole along loop wire or straight line.Though the shock wave generating means of this dust remover can make the concentration of energy of shock wave, can play the effect of impulsing of washing away of shock wave and high velocity air, the gas velocity of its generation is low, and the shock wave equivalent is little, and the removing scope is very limited.
The utility model content
The purpose of this utility model provides and a kind ofly can produce high power velocity of sound shock wave and the high gas shock-wave deashing Impulsive tank of shock wave equivalent.
The technical solution used in the present invention is as follows:
Gas shock-wave deashing Impulsive tank, comprise tank body, gas feed and shock wave outlet, it is characterized in that vertical screen that the inner tank wall welding radially is provided with along tank body, vertical welding with vertical screen is provided with a plurality of annular oriffices concentric with tank body, and the external diameter of annular oriffice is less than the internal diameter of tank body cross section.
Described vertical screen evenly is provided with along inner tank wall, and screen quantity is more than three or three.
The number of described annular oriffice is that annular oriffice equidistantly is provided with more than three or three.
The internal orifice dimension of described annular oriffice is 20%～25% of a described tank body internal diameter.
The height of described vertical screen is 20% of a described tank body internal diameter.
Described tank body is the cylindrical tube body structure.
Described gas feed and shock wave outlet lay respectively at the two ends of tank body.
In the gas impulse dust remover, the detonation energy after need utilizing combustion gas to light to greatest extent, the shock wave that the faster equivalent of generation speed is bigger removes to remove dust stratification.The burning of fuel gas can be divided into three kinds of modes: burning, the peace and quiet burning of fuel gas, the acceleration that can not produce any air-flow; Detonation, when the burning of fuel gas is subjected to less obstruction, meeting detonation generation acceleration air-flow and the shock wave that speed is little, energy is low, but can not produce shock wave; Detonation, when the obstruction that is subjected to when gas combustion was very big, it was very big to produce speed, the high high strength shock wave that energy is very high.The present invention utilizes this principle, and the perturbations of lattice-shaped is set in tank body, and the mixed combustible gas body enters from gas feed and is full of in the whole tank body.When flame ignition that gas is transmitted by import, in jar, vertically produce detonation under the powerful inhibition of the perturbations formed of screen and transverse annular orifice plate, the detonation air-flow sends shock wave through outlet.
The external diameter of the annular oriffice that is provided with in the tank body is less than the internal diameter of tank body cross section, therefore annular oriffice can only be fixed on the screen of vertical setting, leave annular space between annular oriffice and inner tank wall, there is not the air-flow dead angle in the detonation air-flow when tank body flows, do not have the consumption of air-flow power capacity, can produce maximized SHOCK ENERGY.
Beneficial effect of the present invention is, this gas shock-wave deashing is simple and do not have a negative effect with the perturbations of Impulsive tank, can utilize the energy of combustion gas detonation to greatest extent, it finally can produce up to 4-8 overtone speed, equivalent is the shock wave of 1.5Mpa, ash-removal effect significantly improves, and also can thoroughly remove for the stifled ash in the equipment, can be widely used in the deashing scale removal operation of industrial equipment heating surfaces such as various boilers.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further elaborated.
Fig. 1 is the longitudinal profile structural representation of the utility model embodiment;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
As figure, this gas shock-wave deashing is the cylindrical tube structure with the tank body 2 of Impulsive tank, gas feed 1 and shock wave outlet 6 are separately positioned on the two ends of tank body, the inner tank wall welding is along radially-arranged four the vertical screens 3 of tank body, screen evenly is provided with along inner tank wall, be vertically installed with five annular oriffices 5 concentric with vertical screen with tank body, the external diameter of annular oriffice is less than the internal diameter of tank body cross section, five annular oriffices equidistantly are provided with, annular oriffice is fixedly welded on the screen of vertical setting, leave annular space 4 between annular oriffice and inner tank wall, the internal orifice dimension of annular oriffice is about 20% of Impulsive tank tank body internal diameter.
Mixed combustible gas body such as coal gas, natural gas, liquefied petroleum gas etc. are entered in the jar by fuel gas inlet, are full of whole tank body.When gas during by the flame ignition at fuel gas inlet place, the gas in jar produces detonation and is exported by shock wave and sends shock wave under the strong inhibition of perturbation mechanism.Warp is to using the dregs of fat to carry out the deashing performance testing as the petroleum chemical enterprise of raw material with boiler, and the stifled ash in its boiler can be removed fully.
