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.
Claims7
A melamine deposition apparatus comprising:
- an absorption pipe having an open upper end;
- a substantially closed container surrounding said open upper end of said absorption pipe;
- a heatable gas feed pipe mounted in said container for feeding melamine-containing reaction gases downwardly into said open upper end of said absorption pipe;
- a wash liquid feed pipe opening into a lower portion of said container for feeding wash liquid into said container to a level just above a lip of said open upper end of said absorption pipe, such that the wash liquid fed into said container can flow as a continuous film over said lip and down along an inner wall of said absorption pipe;
- an inert gas feed pipe opening into an upper portion of said container for feeding inert gas into said upper portion of said container;
- and
- an extension nozzle mounted to and extending downwardly from a lower end of said gas feed pipe and into said open upper end of said absorption pipe.
