Abstract
An apparatus is provided for the deposition of melamine from hot reaction gases into a wash liquid. The apparatus includes a heated gas feed pipe for introducing the hot reaction gases into an absorption pipe. The gas feed pipe is provided with an extension nozzle, the lower end of which projects coaxially into the absorption pipe. The upper part of the absorption pipe and the gas feed pipe are surrounded by a closed container which serves as a storage vessel for wash liquid. The inner wall of the absorption pipe is constantly washed by flowing wash liquid from the closed container.
