Wherein, be provided with pressue device between described vapor storage and described cylinder, described pressue device is pressurised into high steam by atmospheric steam, and be delivered in cylinder the motion that drives described cylinder, described cylinder promotes the steam soot blowing pipe mouth of pipe that described steam soot blowing pipe offers through burner hearth sidewall and enters burner hearth inside, the junction, rear end of described cylinder and described steam soot blowing pipe is provided with pressure-regulating valve, described pressure-regulating valve regulation and control enter the steam pressure of described steam soot blowing pipe to atmospheric steam, when described steam soot blowing pipe arrive predetermined blow grey position after, described pressue device is not worked, atmospheric steam in described vapor storage directly enters in described steam soot blowing pipe inboard wall of burner hearth is carried out to steam soot blowing by cylinder.
Preferably, in described burner hearth steam soot-blower, described vapor storage communicates with the steam outlet of burner hearth, forms a circulation closed system.
Preferably, in described burner hearth steam soot-blower, the radius of described shower nozzle type steam jet can arrange according to the burner hearth size.
In burner hearth steam soot-blower of the present invention, the steam jet of described steam soot blowing pipe is set to shower nozzle type, increased the effective area of steam soot blowing, due to the shower nozzle type steam jet and the steam soot blowing pipe is pivotally connected and can be fixed on according to actual needs ad-hoc location concentrates injection, thereby effectively avoid blowing grey dead angle.Described vapor storage communicates with the steam outlet of burner hearth, and the steam in burner hearth recycles as the motive force of cylinder, thereby replaces motor, and described steam soot blowing pipe only carries out axially-movable and do not need rotation, has reduced power consumption, has reduced cost.
The accompanying drawing explanation
Fig. 1 is the structural representation of burner hearth steam soot-blower of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art, with reference to the specification word, can implement according to this.
The invention provides a kind of burner hearth steam soot-blower, comprising:
Steam soot blowing pipe 1, its front end is equipped with steam jet 2, the material of described steam jet is oxida-tion-resistant steel, described steam jet is the shower nozzle type steam jet, the head 3 of described shower nozzle type steam jet is hemispherical, offer the steam through hole 4 that a plurality of pore sizes differ on hemispheric convex surface, because the steam through hole is opened on a curved surface, when steam enters steam jet by the steam soot blowing pipe, the impulsive force that on curved surface, each point is subject to does not wait, to the grey effect difference of blowing of inboard wall of burner hearth, the afterbody 5 of described shower nozzle type steam jet connects in the mode that can rotate around described steam soot blowing pipe front end, described steam soot blowing pipe front end is equipped with a turning cylinder 6, the afterbody of described shower nozzle type steam jet is articulated on described turning cylinder, described steam soot blowing pipe front end also offers the chute that an afterbody for described shower nozzle type steam jet slides, the afterbody of described shower nozzle type steam jet is tightly connected and fixes by sealing ring 7 and sliding grain, described sealing ring is a set of, the chute of the diameter of each sealing ring and described steam soot blowing pipe front end is complementary, but the position of opening of each sealing ring is inconsistent, and the diameter series along sealing ring distributes, according to actual needs described shower nozzle type steam jet is fixed on to diverse location, make the shower nozzle type steam jet strengthen blowing ash from the horizontal by certain angle to different parts, if in burner hearth, the knot ash evenly, the shower nozzle type steam jet only needs that level is fixing carries out steam soot blowing to inboard wall of burner hearth,
