Abstract
Abstract A fluidized bed reactor containing a heat exchange apparatus for conveying a heat transfer medium comprising at least one pipe which extends in a vertical direction from the top of the reaction chamber into the fluidized bed with one end of the vertical pipe which points in the direction of the gas flow having a conical tapered end and/or a jacket on the outside of the reactor wall in the form of a serpentine conduit having a rectangular cross section and a domed cover.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A fluidized bed reactor for the preparation of silicon-halogen compounds from the reaction of a silicon containing contact mass with organic halides, said fluidized bed reactor containing a heat exchange apparatus for conveying a heat transfer medium, said heat exchange apparatus having at least one pipe which is suspended vertically from the top of said reactor into the fluidized bed, said pipe having a concically tapered configuration at its end which is opposite to the direction of gas flow in which the inside of said conically tapered section of the pipe is solid, a jacket on the outside wall of said fluidized bed reactor which forms a serpentine conduit having a rectangular cross section which is enclosed on its outer most surface with a cover having a dome-shaped configuration, said jacket is connected to the pipe so thatthe heat transfer medium is conveyed through said jacket into said pipe.
Claim 2
Dependent Claim
149 words
A fluidized bed reactor for the preparation of silicon-halogen compounds from the reaction of a silicon containing contact mass with organic halides, said fluidized bed reactor containing a heat exchange apparatus for conveying a heat transfer medium, said heat exchange apparatus having at least one pipe which is suspended vertically from the top of said reactor into the fluidized bed, said pipe having a concically tapered configuration at its end which is opposite to the direction of gas flow in which the inside of said conically tapered section of the pipe is solid, a jacket on the outside wall of said fluidized bed reactor which forms a serpentine conduit having a rectangular cross section which is enclosed on its outer most surface with a cover having a dome-shaped configuration, said jacket is connected to the pipe so thatthe heat transfer medium is conveyed through said jacket into said pipe.
Claim 3
Dependent Claim
23 words
The fluidized bed reactor of claim 1, wherein the outside surface of the conically tapered section of the pipe has a rounded point.
Claim 4
Dependent Claim
40 words
The fluidized bed reactor of claim 1, wherein the reaction chamber has more than one pipe suspended vertically from the top of the reactor into the fluidized bed with the conically tapered sections of said pipes being interconnected by connectors.
Claim 5
Dependent Claim
32 words
The fluidized bed reactor of claim 3, wherein the connectors consist of flat plates which stand vertically in the reaction chamber and whose narrow sides are connected with the conically tapered sections.
Claim 6
Dependent Claim
44 words
The fluidized bed reactor of claim 1 wherein the rectangular conduit is formed by a metal strip whose lengthwise edge is welded in the form of a spiral onto the reactor wall and its outer most surface is enclosed by a dome-shaped metal strip.
Claim 7
Dependent Claim
49 words
The fluidized bed reactor of claim 5, wherein the rectangular conduit which is formed by a metal strip whose lengthwise edge is welded at right angles onto the reactor wall in the form of a spiral and is enclosed on its outer most surface with a dome-shaped metal strip.
Claim 8
Dependent Claim
24 words
The fluidized bed reactor of claim 5, wherein the outside of the conduit is closed by a welded-on metal strip having a convex dome.
