Abstract
Abstract An apparatus for carrying out chlorinating reactions when extracting metalsuch as titanium, zirconium or the like during the extraction of uranium and thorium during the reprocessing of burned-off fuel and/or breeder elements for core reactors and during the purification of coal and graphite. The device comprises a shaft or blast furnace which is heated by a direct flow of current and while being coaxially surrounded by a mantle or shell communicates through a connection or adapter piece with a subsequent condenser of graphite. The device according to the present invention is characterized primarily in that the shell of the furnace and the adapter piece connecting the furnace with the condenser are made of graphite. The shell of the furnace, the condenser and the adapter piece connecting the shell with the condenser are arranged within a steel casing designed in a gas-tight manner.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
An apparatus for carrying out chlorinating reactions which includes in combination: a shaft furnace comprising a vertical graphite tube having a resistance heating zone, a supply for material to be chlorinated connected to the upper part of the shaft furnact to feed material to said tube, means for feeding chlorine, a graphite shell surrounding said tube, condenser means communicating with said furnace and having an integral tubular adapter piece connecting said condenser means to said furnace, said condenser means and adapter piece being made of graphite with said adapter piece being fixed to said graphite shell at one end and extending outwardly from said furnace to its integral connection to said condenser means on the other end, a withdrawal outlet for the reaction product, a gas tight steel casing surrounding said shell and said condenser means and said adapter piece, said adapter piece extending horizontally outwardly from said shell, said condenser means depending from said adapter piece, and means to heat said adapter piece and incorporated therewith, said adapter piece forming a support for said condenser means.
