Abstract
Abstract A vacuum deaerator including an evacuated tank having an inlet valve at the top thereof, and outlet at the bottom thereof, and a cooling plate assembly mounted within the tank. Liquid received in the tank is deaerated by exposure to the vacuum in the latter and is cooled by the plate assembly prior to exiting through the outlet of the tank.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
Vacuum deaerator apparatus for evacuated removal of gases from fluids, comprising: housing means including an inlet portion thereof, said inlet portion adapted to receive fluids containing gases dissolved therein; first trough means mounted within said housing means and adapted for catching said fluids therein; solid plate means mounted within said housing means, said first trough means being disposed intermediate said inlet portion and said plate means and further including means for regulated and uniform distribution of said fluids therethrough; evacuator means connected to said housing means, said first trough means and said plate means cooperating to cause said fluids to cascade in relatively thin films over said plate means for efficient exposure of said dissolved gases to said evacuator means whereby substantially uniformly to remove said gases from said fluids; second trough means mounted within said housing means and adapted for catching substantially gas-free fluids therein; and cooling means mounted within said housing means, said second trough means being disposed intermediate said plate means and said cooling means and further including means for regulated and uniform distribution of said gas-free fluids therethrough, said second trough means and said cooling means cooperating to chill said gas-free fluids to a preselected temperature.
Claim 2
Dependent Claim
200 words
Vacuum deaerator apparatus for evacuated removal of gases from fluids, comprising: housing means including an inlet portion thereof, said inlet portion adapted to receive fluids containing gases dissolved therein; first trough means mounted within said housing means and adapted for catching said fluids therein; solid plate means mounted within said housing means, said first trough means being disposed intermediate said inlet portion and said plate means and further including means for regulated and uniform distribution of said fluids therethrough; evacuator means connected to said housing means, said first trough means and said plate means cooperating to cause said fluids to cascade in relatively thin films over said plate means for efficient exposure of said dissolved gases to said evacuator means whereby substantially uniformly to remove said gases from said fluids; second trough means mounted within said housing means and adapted for catching substantially gas-free fluids therein; and cooling means mounted within said housing means, said second trough means being disposed intermediate said plate means and said cooling means and further including means for regulated and uniform distribution of said gas-free fluids therethrough, said second trough means and said cooling means cooperating to chill said gas-free fluids to a preselected temperature.
Claim 3
Dependent Claim
46 words
Vacuum deaerator apparatus according to claim 1 wherein said plate means includes a plurality of substantially vertically extending solid plate members disposed in spaced-apart relation, said plate members cooperating to cause fluids containing gases dissolved therein to flow in a plurality of relatively thin films thereover.
Claim 4
Dependent Claim
71 words
Vacuum deaerator apparatus according to claim 1 wherein said cooling means includes a plurality of substantially vertically extending plate elements disposed in spaced-apart relation, said plate elements cooperating to cause said gas-free fluids to flow in a plurality of relatively thin films thereover for efficient and uniform cooling of said gas-free fluids, said plate elements further being cooled to a temperature sufficient to chill said gas-free fluids to said preselected temperature.
Claim 5
Dependent Claim
37 words
Vacuum deaerator apparatus according to claim 3 wherein each of said plate elements is tubular and includes a continuous channel extending therethrough, said channel being adapted for passing a refrigerant therein whereby to cool said plate element.
