Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples, and the embodiment of the utility model includes
But it is not limited to the following example.
Embodiment
As shown in Figures 1 to 4, a kind of spiral attemperator, including attemperator cylinder 1 are arranged in 1 left end of attemperator cylinder
Left shell flange 2, be arranged 2 end of left shell flange and for left part block blind flange 3, be arranged in attemperator cylinder
The right shell flange 4 of 1 right end is crimped on the closure plate 5 on 4 the right of right shell flange, through closure plate 5 and is built in attemperator cylinder
1 top goes out water manifold 6, is arranged and goes out water manifold flange 7 go out 6 right end of water manifold, through closure plate 5 and is built in attemperator
1 lower part water-inlet header 8 of cylinder, is arranged the water-inlet header flange 9 in 8 right end of water-inlet header, and setting joins in water-inlet header 8 and water outlet
6 left part of case and for changing the baffle plate of steam flow direction 10, is connected across 1 inner wall of attemperator cylinder and is used to support into water
Header 8 and the support plate 11 for going out water manifold 6, are connected across water-inlet header 8 and go out the spiral heat exchange tube 12 between water manifold 6, are arranged
In 1 left part sidewall edge of attemperator cylinder and the steam inlet joint 13 of face baffle plate 10, setting is right in attemperator cylinder 1
The steam outlet joint 14 at end sidewalls edge, and the blow-off connection 15 in 1 lower edge of attemperator cylinder is set.
Wherein, the baffle plate 10 is the thin plate with certain bending degree.
Also, the support plate 11 is cross and sets there are two symmetrical pore 16；Wherein water-inlet header 8 and go out
Water manifold 6 is extended through in pore 16.
The water-inlet header flange 9 being connected on water-inlet header 8 endlessly injects cold water, and cold water reaches steam inlet and connects
First 13 end, into water manifold flange 7 is gone out, the cold water of injection is detoured always by spiral heat exchange tube 12 flows out to out water manifold 6, steams
Vapour enters from steam inlet joint 13 inside attemperator cylinder 1, and the steam of entrance changes the direction of motion by baffle plate 10, changes fortune
The steam in dynamic direction is spread in by the gap between support plate 11 around spiral heat exchange tube 12, and spiral heat exchange tube 12 increases it
Heat exchange area makes to reduce by the vapor (steam) temperature of spiral heat exchange tube 12, and right simplified flange 4 has blocked the outlet of steam, attemperator
Steam in cylinder 1 is flowed out by steam outlet joint 14, and air-flow of the steam in attemperator cylinder 1 passes through spiral heat exchange tube 12
Heat is siphoned away, it can be achieved that quick desuperheat, effectively controls the temperature of superheated steam in attemperator.
A large amount of high-temperature steams by water-inlet header 8, spiral heat exchange tube 12, go out the composition of water manifold 6 in attemperator cylinder 1
Heat sink cool down, high-temperature steam can be liquefied as the appearance that droplet is attached to spiral heat exchange tube 12 in the way of cooling
Face cannot continue to be attached to 12 outer surface of spiral heat exchange tube when droplet becomes larger, and droplet is dropped in attemperator cylinder 1,
Then it converges at sewage ditch connector 15 and is discharged.It can avoid the corrosion brought in attemperator cylinder 1 because there is water in this way, it can be big
Amplitude improves the attemperator service life, and providing guarantee for tunnel kiln waste heat boiler safe operation supports.
Above-described embodiment is only the preferred embodiment of the utility model, is not intended to limit the scope of the present invention,
In every case using the design principle of the utility model, and the non-creative variation worked and made is carried out on this basis, it should all
Belong within the scope of protection of the utility model.
