With the waste heat boiler of ∏ type structure, in the ascent stage, flue gas is bottom-up to wash away heat convection pipe, and flue dust is also just mainly collected at and changes
The lower section of heat pipe bundle.Adopting line pulse formula detonation soot-blowing mode blowing deposited dust waste heat boiler at present more, when purging online, big
Granule can down fall, and when cleaning offline, mortar is also to trickle from top to bottom, so soot blower is arranged in the upper of heat exchanger tube
Side, spout down, to avoid granule and mortar to fall into spout.It was verified that in the waste heat boiler ascent stage of ∏ type structure, adopting
Soot-blowing mode from top to bottom is difficult to remove the dust stratification of heat exchange bottom of the tube windward side.
Content of the invention：
The present invention is exactly to overcome deficiency of the prior art, provide a kind of for heat convection pipe have structure simple,
Easy to use, be easy to directly transform on existing, can effectively remove the soot blower of the dust stratification of heat exchange bottom of the tube windward side.
The present invention provides technical scheme below：
A kind of soot blower of heat convection pipe it is characterised in that：It includes blowing pipe, and blowing pipe one end is with air-blast device even
Logical, the other end stretches in furnace wall, is provided with air outlet upwards in its end, is provided with renovating of corresponding matching on air outlet,
Renovate and be connected with drive link, the through hole that one end of drive link passes on furnace wall is connected with the actuating device outside furnace wall, described
Actuating device pass through wire and PLC control module and form the signal of telecommunication to control cooperation.
On the basis of technique scheme, it is additionally provided with technical scheme further below：
One leakproof plug with through hole corresponding matching is respectively equipped with the drive link at described through hole two ends, and described two anti-

Shaft positioned at the drive link outside furnace wall is provided with gag lever post, is spaced a distance respectively in gag lever post both sides
It is provided with and the renovating closing switch and renovate unlatching switch of gag lever post corresponding matching, and described renovate closing switch and renovate out
Breakdown closes and all forms electric signal transmission cooperation by wire and PLC control module.
Invention advantage：
The present invention has the advantages that structure is simple, easy to use, is easy to directly transform on existing, and is solving cigarette
The bottom-up heat exchange bottom of the tube dust stratification washing away heat convection pipe of gas be difficult to cleaning while, also improve boiler heat exchange efficiency with
And heat utilization efficiency；It also avoid the easy blockage problem that underlying spout exists simultaneously；Also setting up additionally by limit switch, effectively
The safety and the service life that ensure that soot blower system；Operation steady in a long-term for steam generator system provides reliable guarantee.
Brief description：
Fig. 1 is the structural representation of the present invention.
Specific embodiment：
As shown in figure 1, a kind of soot blower of heat convection pipe, it includes arranging blowing pipe 2, and blowing pipe 2 one end is with figure not
The air-blast device connection of display, described air-blast device micropulser.
The other end of blowing pipe 2 stretches in the furnace wall 1 below heat convection pipe 1a, is provided with an elbow 2a in its end,
It is provided with level air outlet upwards in elbow 2a.
One hinged seat 2b is provided with the outer wall of air outlet side, hinged seat 2b is hinged with and air outlet opening
Corresponding matching renovate 3.
One drive link 4 of setting, the through hole 1b on furnace wall 1 is passed through in one end of drive link 4, stretches into inside furnace wall 1, at its end
Portion is hinged with a connecting rod 4a, and one end of connecting rod 4a is hinged on the connecting seat renovating on 3 so that drive link 4 can pass through connecting rod
4a pulls and renovates 3 upsets, opens or close the air outlet on blowing pipe 2.
On the shaft of the drive link 4 at through hole 1b two ends, further respectively have a leakproof plug with through hole corresponding matching
Spacing between 5, and described two leakproof plug 5 is greater than the length of through hole.So that drive link 4 pulling is renovated 3 upsets and is opened
Or when closing the air outlet on blowing pipe 2, can effectively block through hole 1b, prevent from leaking out.
The shaft of the drive link 4 of the leakproof plug side in furnace wall 1 outside is provided with a gag lever post 7, described spacing
Bar 7 both sides be spaced a distance be respectively equipped with gag lever post 7 corresponding matching renovate closing switch 6 and renovate unlatching switch 8, and
Described renovate closing switch 6 and renovate that unlatching switch 8 all passes through wire and PLC control module 10 formation electric signal transmission is joined
Close.Described renovate closing switch 6 and renovate open switch 8 between spacing, between described two leakproof plugs 5
Away from deducting the length of through hole 1b.
The tooth bar 4b being axially distributed along it is provided with the shaft of the drive link 4 of gag lever post 7 side.Setting actuating device 9,
Described actuating device 9 is motor, and motor output shaft is provided with the travelling gear 9a with tooth bar 4b corresponding matching.So that
Motor can drive drive link 4 to pull and renovate 3 upsets, open or close the air outlet on blowing pipe 2.
