Title:
SURFACE FLOW-DOWN TYPE CONCENTRATION DEVICE AND SURFACE FLOW-DOWN TYPE CONCENTRATION METHOD, AND DEVICE USING THE METHOD
Document Type and Number:
Japanese Patent JP2015217371
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a surface flow-down type concentration device which is operated in a super heated region or the neighborhood of a boiling point capable of utilizing a high heat flux, enhances heat efficiency and concentration efficiency even when a bumping phenomenon occurs, prevents a heat transfer member from being lengthened and enlarged, can be miniaturized, is released from constraint of an installment space and can provide a low cost.SOLUTION: A surface flow-down type concentration device has such a structure that a plurality of heat medium plates 1 and vaporization plates 2 are piled in a vacuum container 100 connected to vacuumized means. Therein, each heat medium plate 1 includes a heat medium surface and a vaporization surface, each vaporization plate 2 includes a vaporization surface formed of a plurality of flow-down paths of vertical grooves 14 along which raw liquid flows down on one surface and a heat medium plate joint surface opposite to the heat medium plate 1 on a back surface, the heat medium plate 1 and the vaporization plate constitute one set of concentration plate structures on the heat medium surface of the heat medium plate 1 and the heat medium plate joint surface of the vaporization plate 2, the constituted concentration plate structures amount to a plurality of sets, and the vaporization surface of the vaporization plate 2 of one side set and the vaporization surface of the heat medium plate 1 of the other side set are arranged opposite to each other.
