Description
Technical field
The present invention relates to steam soot blowing field more particularly to a kind of hearth steam soot blowers.
Background technology
Existing various hearth soot blowers are under the constraints that sootblowing dielectric flow is in acceptable range, gas
The range of jet stream or water jet is limited, and for heavy duty boiler, section of burner hearth size is very big, and soot blowing running can only will be blown
The ash blowing mouth on furnace wall that grey device spout passes through certain side stretches into burner hearth, then blowback this furnace wall mode, an ash blowing mouth can only
Take some specific regional area of furnace wall into account, this inevitably causes the presence at the soot blowing dead angle of large area, and burner hearth is blown
Ash is also impossible to be properly completed.And blowing pipe should do stretching motion under the action of motor and enter and exit burner hearth, again
Rotation soot blowing is carried out to ensure soot blowing effect by rotary motion, needs to consume a large amount of electric energy.
Invention content
In view of the above technical problems, the present invention has designed and developed a kind of hearth steam soot blower, it is therefore intended that improves and steams
Effective injection of vapour, avoids soot blowing dead angle, while reducing the consumption of electric energy, reduces cost.
Technical solution provided by the invention is:
A kind of hearth steam soot blower, including:
Steam soot blowing pipe, front end are equipped with steam jet, and the material of the steam jet is oxida-tion-resistant steel, described
Steam jet is shower nozzle type steam jet, and the head of the shower nozzle type steam jet is hemispherical, is opened up on hemispherical convex surface
There are a steam passage holes that multiple pore sizes differ, the tail portion of the shower nozzle type steam jet is with can be around steam soot blowing pipe front end
The mode of rotation connects, and steam soot blowing pipe front end is equipped with a rotation axis, the tail portion pivot joint of the shower nozzle type steam jet
In the rotation axis, steam soot blowing pipe front end is further opened with a cunning slided for the tail portion of the shower nozzle type steam jet
Grain, the tail portion of the shower nozzle type steam jet are tightly connected and are fixed by sealing ring and sliding slot, the sealing ring be it is a set of, often
The diameter of one sealing ring and the sliding slot of steam soot blowing pipe front end match, but the position of opening of each sealing ring differs
It causes, the shower nozzle type steam jet is fixed on different location according to actual needs;
Control device comprising vapor storage and cylinder, the vapor storage is connect with described cylinder one end, described
The cylinder other end is connect with the rear end of the steam soot blowing pipe, and the steam soot blowing pipe is under the action of the cylinder in burner hearth
It axially moves;
Wherein, pressue device is provided between the vapor storage and the cylinder, the pressue device steams normal pressure
Vapour is pressurised into high steam, and is delivered to the movement that the cylinder is driven in cylinder, and the cylinder pushes the steam soot blowing pipe
The steam soot blowing pipe nozzle opened up across burner hearth sidewall enters inside burner hearth, and the rear end of the cylinder and the steam soot blowing pipe connects
The place of connecing is provided with pressure-regulating valve, and steam pressure to the normal pressure that the pressure-regulating valve regulation and control enter the steam soot blowing pipe steams
Vapour, after the steam soot blowing pipe reaches scheduled soot blowing position, the pressue device does not work, in the vapor storage
Atmospheric steam is directly entered in the steam soot blowing pipe by cylinder and carries out steam soot blowing to inboard wall of burner hearth.
Preferably, in the hearth steam soot blower, the steam outlet phase of the vapor storage and burner hearth
It is logical, form a circulation closed system.
Preferably, in the hearth steam soot blower, the radius of the shower nozzle type steam jet can be according to burner hearth
Size is arranged.
In hearth steam soot blower of the present invention, it sets the steam jet of the steam soot blowing pipe to the seedpod of the lotus
Formula increases the effective area of steam soot blowing, since shower nozzle type steam jet is pivotally connected with steam soot blowing pipe and can be according to reality
Border, which needs to be fixed on specific position, carries out concentration injection, to effectively avoid soot blowing dead angle.The vapor storage and burner hearth
Steam outlet communicates, and is recycled the steam in burner hearth as the motive force of cylinder, to replace motor, and the steam
Blowing pipe only carries out being axially moved and is not required to rotate, and reduces power consumption, reduces cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of hearth steam soot blower of the present invention.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
The present invention provides a kind of hearth steam soot blower, including:
Steam soot blowing pipe 1, front end are equipped with steam jet 2, and the material of the steam jet is oxida-tion-resistant steel, institute
It is shower nozzle type steam jet to state steam jet, and the head 3 of the shower nozzle type steam jet is hemispherical, is opened on hemispherical convex surface
Equipped with the steam passage holes 4 that multiple pore sizes differ, since steam passage holes are opened on a curved surface, steam passes through steam soot blowing
It each puts the impact force being subject to when pipe enters steam jet, on curved surface to differ, the lotus different to the soot blowing effect of inboard wall of burner hearth
The tail portion 5 of canopy steam jet is connected in a manner of it can be rotated around steam soot blowing pipe front end, steam soot blowing pipe front end
One rotation axis 6 is installed, the tail portion of the shower nozzle type steam jet is articulated in the rotation axis, steam soot blowing pipe front end
