摘要： A process and apparatus for the separation of vaporous heavy metal compounds from a carrier gas wherein the heavy metal compounds are cooled and desublimed. An apparatus for carrying out this process has a melting furnace with a discharge opening for a gas/ vapor mixture, which leads to a cooling device.Vaporous heavy metal compounds can be separated from a carrier gas on a large industrial scale. In addition, the apparatus for carrying out this process is easy to operate. The gas/vapor mixture is turbulently mixed immediately after the discharge from the furnace in a mixing section with cold air and is thus cooled. During this cooling, the vaporous heavy metal compounds desublime and are filtered as particles in a filter.

摘要： A process for separating off poisonous volatile chemical compounds from a mixture (7) of solid particles having a particle size of up to 200 .mu.m, the mixture being brought continuously or intermittently at an average rate of 5.degree. to 200.degree. C./min in zones of progressively increasing temperature up to 1350.degree. C. and the poisonous chemical compounds being evaporated and forced to leave the reaction space (6). The poisonous compounds are subsequently condensed and discharged. The non-evaporated residue is gradually melted, and the melt (8) is continuously or intermittently discharged from the reaction space (6) and solidified. The particles carried over into the gas phase are preferably retained by a hot gas filter, liquefied and passed into the melt.
