摘要： In an acidic treatment liquid processing apparatus, a space between a first electrode and a second electrode spaced from each other is separated by a first diaphragm permeable and a second diaphragm into a first chamber, a second chamber, and a third chamber. While the first chamber is fed with an acidic treatment liquid containing a dichromate ion and a metal cation, the second chamber is fed with a first acid aqueous solution, and the third chamber is fed with a second acid aqueous solution, a voltage is applied using the first electrode as an anode and the second electrode as a cathode.

摘要： A heat exchanger according to one embodiment includes: a heat exchange core; a shell provided to surround the heat exchange core; and a first partition wall that is provided in a space surrounded by an outer surface of the heat exchange core and an inner surface of the shell, and partitions the space into a first header space communicating with the heat exchange core and a second header space communicating with the heat exchange core. The first header space and the second header space are adjacent to each other, separated by the first partition wall.

摘要： A heat exchanger including: a heat exchanger main body forming a flow path through which a fluid circulates; heat transfer tubes arranged side by side so as to extend in an extending direction of the flow path; and a baffle plate group having a plurality of baffle plates provided with gaps therebetween in the extending direction of the flow path while supporting the heat transfer tubes. The baffle plates are provided so as to each occupy only a portion of the flow path cross section when viewed from the extending direction of the flow path, and the baffle plates of the baffle plate group are provided such that at least a portion of mutually occupied areas do not overlap, and that the entire area of the flow path cross section is occupied by combining the mutually occupied areas, as seen from the extending direction of the flow path.
