Abstract
Abstract A direct contact condenser wherein a plurality of vertically spaced, apertured elements are disposed on each of two opposing sides of the condenser inlet. The apertured elements of each plurality cooperate to provide a tortuous steam flow passage communicating with the condenser inlet, and are provided with a cooling liquid whereby the liquid is discharged in streams through the steam flow passages and forms the primary condensing medium of the condenser.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
242 words
A direct contact condenser comprising a horizontally elongated shell, means defining a generally vertical steam inlet duct having an upper end for receiving steam and a lower end in said shell for discharging steam to said shell, said steam inlet duct being laterally generally centrally of said shell to provide portions of said shell on opposite sides of said steam inlet duct and said steam inlet duct at least adjacent its said lower end extending the length of said shell to discharge steam to such shell portions throughout the length of said shell, a first plurality of apertured elements in one of such shell portions vertically spaced along one side of said steam inlet duct, a second plurality of apertured elements in the other of such shell portions vertically spaced along the other side of said steam inlet duct, the apertured elements of each said plurality being staggered to define a tortuous steam flow passage which at its lower end communicates with said lower end of said steam inlet duct and upwardly extends successively below each apertured element of the plurality, means for supplying cooling liquid to the apertured elements whereby the latter discharge streams of cooling liquid through said tortuous steam flow passages, and means at the upper ends of said tortuous steam flow passages providing labyrinth passages for discharging noncondensable gases from said tortuous steam flow passages, said streams of cooling liquid being the primary condensing medium of the condenser.
Claim 2
Dependent Claim
242 words
A direct contact condenser comprising a horizontally elongated shell, means defining a generally vertical steam inlet duct having an upper end for receiving steam and a lower end in said shell for discharging steam to said shell, said steam inlet duct being laterally generally centrally of said shell to provide portions of said shell on opposite sides of said steam inlet duct and said steam inlet duct at least adjacent its said lower end extending the length of said shell to discharge steam to such shell portions throughout the length of said shell, a first plurality of apertured elements in one of such shell portions vertically spaced along one side of said steam inlet duct, a second plurality of apertured elements in the other of such shell portions vertically spaced along the other side of said steam inlet duct, the apertured elements of each said plurality being staggered to define a tortuous steam flow passage which at its lower end communicates with said lower end of said steam inlet duct and upwardly extends successively below each apertured element of the plurality, means for supplying cooling liquid to the apertured elements whereby the latter discharge streams of cooling liquid through said tortuous steam flow passages, and means at the upper ends of said tortuous steam flow passages providing labyrinth passages for discharging noncondensable gases from said tortuous steam flow passages, said streams of cooling liquid being the primary condensing medium of the condenser.
Claim 3
Dependent Claim
26 words
A direct contact condenser according to claim 1, wherein said labyrinth passage providing means comprises baffle means disposed below the uppermost apertured element of each plurality.
Claim 4
Dependent Claim
84 words
A direct contact condenser according to claim 2, wherein said apertured elements each extend the length of the shell, said cooling liquid supply means comprises a chamber bounded at its lower end by the uppermost apertured element of each said plurality, and the apertured elements of each said plurality are arranged to cause cooling liquid discharged by the uppermost apertured element of the plurality to pass downwardly through therebelow ones of the apertured elements and then be discharged to the bottom of said shell.
Claim 5
Dependent Claim
40 words
A direct contact condenser according to claim 3, further comprising baffle means extending the length of said shell below said lower end of said steam inlet duct for directing steam from such lower end towards said tortuous steam flow passages.
