直接接触式熱交換器およびこれを用いた固体高分子型燃料電池システム

Japanese Patent JP5755526

B2

PROBLEM TO BE SOLVED: To provide a compact direct contact type heat exchanger of low pressure loss.SOLUTION: The direct contact type heat exchanger 1 includes a casing 2 including: a water inlet 5 through which humidifying water is supplied from a top part thereof; a water outlet 6 through which the humidifying water is discharged from a bottom part thereof; a gas inlet 3 through which the gas flows in from a side face thereof, and a gas outlet 4 through which the gas flows out from a position higher than the gas inlet 3 of the side face. A spiral plate 40 has a spiral part 41 disposed to be in contact with an inner periphery of the casing 2 and formed from a bottom part toward a top part of the casing 2 and from a first lap to an m-th lap (m is a number larger than 1) in sequence and spirally so that a gas flow passage and a water flow passage are formed. In the gas flow passage, the gas ascends while swirling from the gas inlet 3 and flows out of the gas outlet 4. The water flow passage is formed in a space where the gas flow passage is formed, and is formed in a direction opposite to the gas flow passage. In the water flow passage, the humidifying water descends while swirling from the water inlet 5 and is discharged from the water outlet 6.
