FREMGANGSMAADE TIL ADSKILLELSE AF DAMPFORMIGE TUNG METALFORBINDELSER FRA EN BAEREGAS OG APPARAT TIL GENNEMFOERELSE AF FREMGANGSMAADEN

摘要

In the separation of vaporous heavy metal compounds from a carrier gas, these are cooled and desublimate. An apparatus for carrying out this process has a melting furnace (1) with a discharge opening for a gas/vapour mixture, leading to a cooling device. …A method for separating vaporous heavy metal compounds from a carrier gas is to be provided which can be applied on a large industrial scale. In addition, an apparatus for carrying out this method is to be provided, which is easy to operate. This is achieved when, immediately after the discharge, the gas/vapour mixture is turbulently mixed with cold air in a mixing section (4) and thus cooled. During this cooling, the vaporous heavy metal compounds desublimate and are filtered out as particles in a filter (6). ……
