| 摘要 |
<p>The present invention relates to a method of cleansing contaminated gases, particularly hot process gases (100) that contain at least one first metal in a gaseous state. Condenser elements or elements (10) that comprise a condensation-promoting material are introduced into the flow of process gas in a first condensing stage, wherewith the temperature of the elements (10) lies beneath the temperature of condensation of said first metal. The gaseous metal condenses on the surfaces (11) of the condenser elements (10), which are then removed from the process-gas flow. The elements (10) are in the form of granules. Used elements (10) are cooled at a location externally of the process-gas flow and returned to said process-gas flow. The invention also relates to an arrangement for carrying out the method.</p> |
