For prior art defect and deficiency, the purpose of the present invention is to propose to a kind of simple in structure, and soot blowing effect is more preferable
Shock wave soot blower.
Technical solution of the present invention is as follows：
The present invention provides a kind of more single holes with shock wave soot blower is pressed, including shock-wave generating device, the shock-wave generating device
Output terminal is connected with an at least blowing pipe, and every soot blowing pipe surface is provided with one or two shock wave launch hole；
When blowing pipe be one and the blowing pipe on shock wave launch hole be two when, the pitch-row of the shock wave launch hole is 50-
80cm, and in same level；
When blowing pipe is more, the level interval between every two adjacent shock wave launch holes is identical, pitch-row 50-
80cm, and towards identical.
As the preferential of above-mentioned technical proposal, the shock wave launch hole is round hole or slotted eye.
As the preferential of above-mentioned technical proposal, when launch hole is slotted eye, maximum diameter of hole 6-8cm works as transmitting
When hole is round hole, aperture 6-8cm.
As the preferential of above-mentioned technical proposal, the aperture of the shock wave launch hole is 6-8cm.
As the preferential of above-mentioned technical proposal, the blowing pipe is square tube.
As the preferential of above-mentioned technical proposal, the blowing pipe is located at the part connection rotating device outside furnace body, so that
The shock wave launch hole of the soot blowing pipe surface can rotate soot blowing in furnace body.
The advantageous effect that the present invention is brought is：
More single holes proposed by the present invention are with shock wave soot blower is pressed, and the burning of fuel gas can be with shape with explosion in shock-wave generating device
Into the supersonic flows of gas, shock wave phenomena is just had in the place of the supersonic flows of Supersonic Inlet, and the pressure of gas
By force, density, temperature, one numerical value of rising of jumping are shock wave.Shock-wave generating device combustion explosion of the present invention forms shock wave, passes through
One or two unique shock wave launch hole injection on every blowing pipe, since each blowing pipe only sets one or two spray
Loophole Gu to form the pressure of ray identical for it, while increases soot blowing effect same towards resonance effect is reached in plane.Institute
Blowing pipe connection power part is stated so that its left and right to be driven to move up and down movement, increases projected area, to adapt to the width of different furnace bodies
Problem；Meanwhile the quantity of the blowing pipe can be increased or decreased according to the size of furnace body, to solve depth length issue.This
It invents the more single holes proposed to design by hydrodynamic turbulence layer with pressure shock wave soot blower, shock-wave generating device part is fixed and set
It puts, power section installs driving blowing pipe outside furnace body and enters in stove and move.More single holes proposed by the present invention are same to press shock-wave ash blowing
Device has the characteristics that simple in structure, use cost is low, soot blowing effect is good, applied widely.
