Abstract
The present invention relates to wall at the top of a kind of heat exchanger steam sootblower, including half retractable soot blower, soot blower supporting construction and flue；The soot blower supporting construction is on wall at the top of flue；At the top of the flue elongated notch is provided with wall, the soot blower supporting construction is located at notch both sides and surrounds sealing air chamber, the soot blower supporting construction be located at the soot blower support frame inwall of notch both sides provided with cavernous structure and in set sealing air pipe access point；The soot blower supporting construction upper surface is provided with limit guide rail, and the half retractable soot blower bottom is provided with the roller being engaged；The blowing pipe of half retractable soot blower is stretched at the top of flue in the notch of wall.The beneficial effects of the invention are as follows：Single steam sootblower is set to packaged type, opposite side movement side soot blowing without purging the multiple soot blowers of the single heat-transfer surface setting of effect to reach, and can better ensure that whole heat-transfer surface, without dead angle, prevents the dust stratification of heat-transfer surface from blocking.
Description
Technical field
, especially can the whole heat exchanger heat-transfer surface of all standing the present invention relates to a kind of steam sootblower for heat exchanger
Steam sootblower.
Background technology
Many coal-burning power plants install low-level (stack-gas) economizer or flue gas heat-exchange unit additional, to realize flue gas heat recovery, or
Reach energy-conservation purpose, or lifting chimney emission temperature to solve the " stone of coal-burning power plant's generally existing for heating boiler feed water
Cream rain " problem.Partial fume cooler is arranged in before absorption tower, and longtime running easily causes the dust stratification of heat-transfer surface, influence heat exchange
Efficiency, even can block whole heat-transfer surface, the long-term safety stable operation to system brings larger hidden danger when serious.
Several half are set to stretch in the dust stratification of heat exchanger tube in gas cooler, low-level (stack-gas) economizer or flue gas heat-exchange unit to mitigate
Formula soot blower, but because most of all have purging dead angle, it is easily caused heat-transfer surface blocking.Rake soot blower is set to easily cause
Pressure is difficult equilibrium at spray nozzle clogging, and each nozzle, does not reach purging effect.
The content of the invention
It is an object of the invention to overcome prior art not enough, there is provided a kind of rational in infrastructure, good heat exchanger of soot blowing effect
Steam sootblower.
To achieve the above object, present invention employs following technical scheme：
Wall at the top of heat exchanger steam sootblower, including half retractable soot blower, soot blower supporting construction and flue；It is described
Soot blower supporting construction is on wall at the top of flue；At the top of the flue elongated notch, the soot blower are provided with wall
Supporting construction is located at notch both sides and surrounds sealing air chamber, and the soot blower that the soot blower supporting construction is located at notch both sides is supported
Frame inwall provided with cavernous structure and in set sealing air pipe access point；Led provided with spacing the soot blower supporting construction upper surface
Rail, the half retractable soot blower bottom is provided with the roller being engaged；The blowing pipe of half retractable soot blower stretches into flue
In the notch of top wall.
As preferred:The roller is four.
The beneficial effects of the invention are as follows：
On the basis of the present invention is based on the design of half retractable soot blower, single steam sootblower is set to packaged type,
Opposite side moves side soot blowing, without purging the multiple soot blowers of the single heat-transfer surface setting of effect to reach, and can better ensure that whole
Heat-transfer surface prevents the dust stratification of heat-transfer surface from blocking without dead angle.This steam sootblower can be moved on guide rail, install sealing air at guide rail additional
Isolate flue gas and air, it is ensured that whole heat-transfer surface is all covered, and can effectively reduce dust stratification in flue gas, more preferably ensures the length of heat exchanger
Phase stable operation.Isolate flue gas and air provided with sealing air, effectively prevent the leakage of flue gas.

Embodiment
The present invention is described further with reference to embodiment.The explanation of following embodiments is only intended to help and understands this
Invention.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, also
Some improvement and modification can be carried out to the present invention, these are improved and modification also falls into the protection domain of the claims in the present invention
It is interior.
Wall 3 at the top of heat exchanger steam sootblower, including half retractable soot blower 1, soot blower supporting construction 2 and flue；
The soot blower supporting construction 2 is on wall 3 at the top of flue；Elongated notch is provided with wall 3 at the top of the flue, it is described
Soot blower supporting construction 2 is located at notch both sides and surrounds sealing air chamber 6, and the soot blower supporting construction 2 is located at notch both sides
Soot blower support frame inwall 8 provided with cavernous structure and in set sealing air pipe access point 7；The upper end of soot blower supporting construction 2
Face is provided with limit guide rail 5, and the bottom of half retractable soot blower 1 is provided with the roller 4 being engaged；Half retractable soot blower 1
Blowing pipe stretch at the top of flue in the notch of wall 3.Half retractable soot blower 1 is arranged at the top of flue, by performing structure
Pushing rolling wheels 4 are moved along flue wall.Executing agency carries out distant place control operation by DCS.
When using：Half telescopic steam sootblower 1 is located at the flue rightmost side (or leftmost side), when soot blowing signal is sent, steams
Vapour soot blower 1 proceeds by soot blowing action, and the soot blowing when longitudinally moving down is finished until soot blower 1 is flexible.Then soot blower
1 in the case where performing the driving of structure by roller 4 along guide rail 5 with 1m/s (adjustable) speed along 3 transverse shiftings at the top of flue, up to blowing
Grey device 1 moves to the leftmost side (or rightmost side), and then soot blower 1 moves to the rightmost side from the leftmost side (or rightmost side) in a similar manner
(or leftmost side), soot blower, which shrink, turns into most original state, and completion is once purged.Can daily it be entered according to dust concentration situation
Row is repeatedly purged.
System sets enclosed air system, and perforate on the support structure 2, sealing air is introduced since then, and the inner chamber of supporting construction 2 is sky
The heart, it is interior to be full of sealing air, at the hole injection on inwall 8, to overcome flue gas malleation.
