Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, vacuum evacuation device is restrained in a kind of Air-Cooling Island fair current of the utility model, including Air-Cooling Island and pumping are very
Empty device 10, Air-Cooling Island include 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 be hollow cylinder, the upper tube half of condensate tank 7 without leave centre to
Both ends incrementally increase, and cause edge protuberance, internal to form gas chamber, the plenum roof phase of vacuum evacuation device 10 and condensate tank 7
Connection, to extract the indoor non-condensing steam of gas and non-condensable gas out.Condensate tank 7 is special designing, and common air-cooled
Island is different, and water tank upper half caliber slowly increases, until edge protuberance can be presented in end, forms gas chamber, facilitates vacuum evacuation device 10
Extract incondensable gas out.
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
