Specific embodiment
Following further describes the present invention with reference to the drawings.
As shown in Figure 1 and Figure 2, vacuum evacuation device, including Air-Cooling Island and vacuum means are restrained in a kind of Air-Cooling Island fair current of the present invention
10 are set, Air-Cooling Island includes steam-distributing pipe 3, and the entrance of fair current tube bank 4 is connected with the lower end of steam-distributing pipe 3, fair current tube bank
4 outlet be connected with condensate tank 7, condensate tank 7 is hollow cylinder, and the upper tube half of condensate tank 7 is intermediate to both ends without leave
It incrementally increases, causes edge protuberance, internal to form gas chamber, vacuum evacuation device 10 is connected with the plenum roof of condensate tank 7,
The indoor non-condensing steam of gas and non-condensable gas to be extracted out.Condensate tank 7 is special designing, not with common Air-Cooling Island
Together, water tank upper half caliber slowly increases, until edge protuberance can be presented in end, forms gas chamber, vacuum evacuation device 10 is facilitated to extract out
Incondensable gas.
The solidifying gas unit section of Air-Cooling Island is A type structure, and adverse current tube bank 5, adverse current are additionally provided on the wall surface of Air-Cooling Island two sides
The upper end of tube bank 5 is connected with the first water ring vacuum pump 6.
As shown in figure 3, vacuum evacuation device 10 includes the second water ring vacuum pump 18, collection device 17, vacuum meter 13, air water point
From tank 15 and exhaust valve 16, valve 12 is arranged on the vacuum lead 11 being connected with the gas chamber end, the rear end of valve 12
Sequentially it is equipped with vacuum meter 13, the second water ring vacuum pump 18, gas water separation tank 15, exhaust valve 16 and collection device 17.Vacuum meter 13
It needs to be mounted on tee tube 14.
Exhaust tube 11 used by entire vacuum evacuation device 10 is the pipeline that caliber is Ф 10mm ~ Ф 20mm, the second water ring
Vacuum pump 18 can restrain 4 to fair current and carry out vacuumize process.In use, opening valve 12 and drain tap 16, the second water ring
The non-condensing steam of tail end is restrained in fair current by vacuum lead 11 for vacuum pump 18 and non-condensable gas is extracted out, passes through air water point
From tank 15, is handled respectively by the condensed water of extraction is gentle, water is collected into collection device 17, gas is discharged by exhaust valve 16
It goes out, when gauge 13 is shown as setting negative pressure, closes the second water ring vacuum pump 18, turn off valve 12 and exhaust valve 16,
Entire vacuum is completed.When it is implemented, collection device 17 can also be connected by pipeline with gully, collection device 17
The condensed water being collected into is flowed into gully, to carry out secondary use.
1 steam discharge of steam turbine enters fair current tube bank 4 along blow-off line 2 and steam-distributing pipe 3 from top to bottom, and most of steam exists
It is condensed in fair current tube bank 4, condensed water and steam co-flow.Simultaneously because the connecting pipe between concurrent-countercurrent is equipped with centainly
Angle, the steam not condensed completely has sufficient space and time sufficiently to be condensed, and by this time still without solidifying
The vacuum evacuation device 10 that the steam and non-condensable gas of knot can restrain 4 ends by fair current is extracted out, and cooling efficiency is improved.
Remaining not condensed steam carries on-condensible gas and enters adverse current tube bank 5.In adverse current tube bank 5, steam flows quilt from bottom to top
All condensations, condensed water flow into bottom condensate tank 7 from top to bottom under the effect of gravity, flow into the condensed water of condensate tank 7 then
By down-comer 8, extracted out under the action of condensate pump 9.Due to steam and condensed water reverse flow, adverse current tube bank is not in
Hot-well depression and freezing phenomena, on-condensible gas are aspirated and are excluded by water ring vacuum pump 6 on 5 tops of adverse current tube bank.
Although being particularly shown and describing the present invention, those skilled in the art referring to its exemplary embodiment
It should be understood that in the case where not departing from the spirit and scope of the present invention defined by claim form can be carried out to it
With the various changes in details.
