Abstract
The utility model relates to a falling film absorber. The falling film absorber comprises a cylinder body, wherein the cylinder body sequentially comprises a loading section, a film-forming absorption section and a separation section from top to bottom, a liquid inlet and a gas outlet are formed in the loading section, and a liquid outlet and a gas inlet are formed in the separation section; a flow guide pipe is arranged at an opening in the upper part of an absorption tube and is higher than the liquid inlet, after the liquid enters the loading section, a liquid surface is firstly formed in the loading section, and the liquid flows into the absorption tube under the action of the flow guide pipe. According to the falling film absorber, by utilizing the flow guide pipe, the liquid surface is uniformly distributed, so that the falling film absorber has the advantage of high absorption efficiency.
