Abstract
Abstract Apparatus for drying the steam of a steam-water mix generated by a steam generator has an axial cyclone arranged above the steam generator for separating at least a portion of the water from the steam-water mix so as to yield separated water and a remaining steam-water mix and for passing the water and the remaining mix in an upward direction. A plurality of counter-flow cyclones for receiving therein the separated water separated from the mix in said axial cyclone are also provided and each of the counter-flow cyclones has a wall defining a turbulence chamber, a tube extending into the chamber, and inlet guide vanes disposed concentric to the tube for imparting a spin motion to the separated water for separating the latter into water and clarified steam in the chamber. A tornado-flow separator for separating the remaining mix into additional water and clarified steam is disposed above and coaxial with the axial cyclone. The tornado-flow separator has a lower axial inlet for admitting the remaining mix as well as having an upper outlet for discharging clarified steam. The tornado-flow separator also has an upper auxiliary gas inlet coaxial with the upper outlet for admitting the clarified steam separated in the counter-flow cyclones.

Apparatus for drying the steam of a steam-water mix generated by a steam generator, comprising an axial cyclone arranged above the steam generator for separating at least a portion of the water from the steam-water mix so as to yield separated water and a remaining steam-water mix and for passing the water and the remaining mix in an upward direction, a plurality of counter-flow cyclones for receiving therein the separated water separated from the mix in said axial cyclone, each of said counter-flow cyclones comprising a wall defining a turbulence chamber, a tube extending into said chamber, and inlet guide vane means disposed concentric to said tube for imparting a spin motion to the separated water for separating the latter into water and clarified steam in said chamber, and a tornado-flow separator for separating the remaining mix into additional water and clarified steam, said tornado-flow separator being disposed above and coaxial with said axial cyclone, said tornado-flow separator having a lower axial inlet for admitting the remaining mix as well as having an upper outlet for discharging clarified steam, said tornado-flow separator also having an upper auxiliary gas inlet coaxial with said upper outlet for admitting the clarified steam separated in said counter-flow cyclones.
Claim 3
Dependent Claim
47 words
Apparatus of claim 1, said axial cyclone having a tube-like turbulence chamber, and said plurality of counter-floW cyclones being disposed outside said tube-like turbulence chamber so as to place said inlet guide vane means at the same elevation as the upper end of said tube-like turbulence chamber.
Claim 4
Dependent Claim
23 words
Apparatus of claim 1, said tornado-flow separator having water outlets feeding into corresponding ones of said cyclones at the respective lower regions thereof.
Claim 5
Dependent Claim
29 words
Apparatus of claim 1, said axial cyclone having a tube-like turbulence chamber, said inlet guide vane means being disposed within said tube-like turbulence chamber at the outer region thereof.
Claim 6
Dependent Claim
41 words
Apparatus of claim 4, said tornado-flow separator having a water outlet for the water, separated therein, said counter-flow cyclones having respective water outlets, said outlet of said separator and said water outlets of said cyclones terminating in a common discharge channel.
Claim 7
Dependent Claim
19 words
Apparatus of claim 1, said tubes of said cyclones being connected with said auxiliary gas inlet said tornado-flow separator.
Claim 8
Dependent Claim
17 words
Apparatus of claim 1, said lower axial inlet of said tornado-flow separator having an aperture disposed therein.
Claim 9
Dependent Claim
72 words
Apparatus of claim 1, said axial cyclone comprising a wall defining a turbulence chamber, a flow body beneath said turbulence chamber, and guide vanes disposed around said flow body for imparting a spin motion to the steamwater mix, and recess means in the upper end of said flow body for stabilizing the funnel-like figure caused by said spin motion and defining the boundary between the separated water and the remaining water mix.
Claim 10
Dependent Claim
15 words
Apparatus of claim 8, said recess means being a recess having an approximately concave shape.
Claim 11
Dependent Claim
60 words
Apparatus of claim 1, wherein the spin motion imparted to the separated water causes a funnel-like figure of steam to be formed in each of said counter-flow cyclones, each of said cyclones comprising a stabilization body for stabilizing said figure, said stabilization body being a shell-like body opening toward the upper region of said turbulence chamber of said counter-flow cyclone.
