Description
Technical field
It the utility model is related to thermal power plant equipment technical field, and in particular to a kind of oxide skin purges boiler high temperature certainly
Vapor heat exchanger.
Background technology
With advances in technology, the direction of fired power generating unit towards high parameter, large capacity is developed.The raising of steam parameter is into one
Step improve requirement of the station boiler to high temperature superheater and high temperature reheater material, to the anti-pipe of high temperature and high pressure steam pipeline outside
Steam oxidation performance requirement is very high in high temperature corrosion and anti-pipe.But the generation of pipeline scale inside can not be still avoided with coming off
Process, if supercritical boiler high temperature steam heat exchanger scale inside comes off, easily blocks elbow, causes boiler high temperature to steam
Vapour heat exchanger tube panel elbow stress concentration, ultimately results in corrosion cracking, causes and force the accidents such as blowing out.
The content of the invention
In order to solve the above-mentioned technical problem the utility model provides a kind of oxide skin and purges boiler high temperature vapor heat exchanger certainly,
Prevent oxide skin from avoiding oxide skin in elbow deposition, increase substantially the operational reliability of boiler high temperature vapor heat exchanger.
The technical solution of the utility model is：A kind of oxide skin is from boiler high temperature vapor heat exchanger is purged, by boiler high temperature
Vapor heat exchanger tube bank entrance header, cyclone, the tube bank of boiler high temperature vapor heat exchanger, boiler high temperature vapor heat exchanger are restrained out
Mouth header composition, the cyclone are arranged in boiler high temperature vapor heat exchanger tube bank entrance header and boiler high temperature vapor heat exchanger
Junction is restrained, swirl vane is arranged inside the cyclone, the swirl vane is all along boiler high temperature vapor heat exchanger pipeline
To being evenly arranged 2 ~ 5.
The operation principle of the utility model is：Steam enters eddy flow by boiler high temperature vapor heat exchanger tube bank entrance header
Device, inside cyclone, steam stream crosses eddy flow blade-shaped can be in boiler high temperature vapor heat exchanger heat exchanger tube into eddy flow, the eddy flow
Tube wall is purged in beam, tiny oxide skin is removed by purging, and is carried by steam eddy flow to boiler high temperature vapor heat exchanger
Restrain in outlet header.
The utility model has the advantages that：Cyclone is arranged in boiler high temperature vapor heat exchanger U heat exchange entrance, makes steam
Eddy flow is being formed in pipe, oxide skin is on the one hand being purged, oxide skin fritter is come off, avoid coming off on a large scale, on the one hand rotate
Steam flow carries solid particle, prevents oxide skin from avoiding oxide skin in elbow deposition, increases substantially boiler high temperature steam heat-exchanging
The operational reliability of device.

3 junctions are restrained with boiler high temperature vapor heat exchanger.
In the present embodiment, as shown in Fig. 2, the inside of the cyclone 2 arrangement swirl vane 20, the swirl vane 20 is along pot
Stove high temperature steam heat exchanger pipeline is arranged circumferentially 2 ~ 5.
In the present embodiment, the cyclone 2 is arranged in the part U-shaped pipe of boiler high temperature vapor heat exchanger tube bank 3.
The operation principle of the present embodiment is：Steam enters cyclone by boiler high temperature vapor heat exchanger tube bank entrance header 1
2, inside cyclone 2, steam stream crosses swirl vane 20 and forms eddy flow, which can exchange heat in boiler high temperature vapor heat exchanger
Tube wall is purged in tube bank 3, tiny oxide skin is removed by purging, and is carried by steam eddy flow to boiler high temperature steam heat-exchanging
In device tube bank outlet header 4.
The preferred embodiment to the utility model is described above, it should be pointed out that the utility model not office
It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as using the common side in this area
Formula is practiced；Any those skilled in the art, in the case where not departing from technical solutions of the utility model ambit, foundation
The technical essence of the utility model still falls within this to any simple modifications, equivalents, and modifications made for any of the above embodiments
In the range of the protection of utility model technical solution.
