PURPOSE: To reduce a possibility of interruption a flowing solution and to easily flow the flowing solution uniformly on the outer peripheral surface of a heat transfer pipe thereby to improve the substance transfer characteristic.
CONSTITUTION: In the case of vapor absorption, a dense solution 10 introduced from a solution inlet pipe 6 enters an upper chamber 1a of a casing 1, and flows down from a gap 15 formed between a partitioning plate 13 and a heat transfer pipe 2 along the outer peripheral surface of the heat transfer pipe 2. Then, the solution 10 absorbs a vapor 12 from a vapor inlet pipe 7 and emits heat to become a dilute solution 11. The dilute solution is taken out of the device from a solution outlet pipe 5 via a solution take-out pipe 9 by means of a pump 8. The dense solution to which has become surplus in the upper chamber 1a passes through a return pipe 14 and is introduced into a low chamber 1b. In a case where a vapor is generated, the dilute solution 11 introduced from the solution inlet pipe 6 enters the upper chamber 1a, and flows down from the gap 15 between the partitioning plate 13 and the heat transfer pipe 2 along the outer peripheral surface of the heat transfer pipe 2 to generate a vapor 12. The dense solution 10 which generates the vapor and has a high concentration is taken out of the casing 1 through the solution take-out pipe 5.
