Abstract

Anordning for trykkutveksling mellom fluider, innbefattende minst ett hus anordnet med minst ett, fortrinnsvis to, fluidinnløp (4, 5) og med minst ett, fortrinnsvis to, fluidinnløp (4, 5) og et indre rom. Det indre rommet opptar en trykkutvekslingsenhet (8, 9) anordnet med minst ett trykkoverføringselement som deler det indre rommet i trykkutvekslingsenheten (8, 9) i minst et første og et andre kammer. Hvert kammer har minst én strømningspassasje og trykkutvekslingsenheten (8, 9) er bevegbart anordnet i huset (2, 3) slik at derved den i det minste ene strømningspassasjen kan bringes til flukt med i det minste ett av fluidinnløpene (4, 5) eller fluidutløpene (6, 7), for transport av fluid inn i og ut fra hvert kammer. Oppfinnelsen vedrører også en fremgangsmåte for trykkutveksling mellom fluider.Apparatus for pressure exchange between fluids, including at least one housing provided with at least one, preferably two, fluid inlets (4, 5) and with at least one, preferably two, fluid inlets (4, 5) and an interior space. The inner space accommodates a pressure exchange unit (8, 9) provided with at least one pressure transfer element dividing the inner space of the pressure exchange unit (8, 9) into at least one first and second chamber. Each chamber has at least one flow passage and the pressure exchange unit (8, 9) is movably arranged in the housing (2, 3) so that the at least one flow passage can be flush with at least one of the fluid inlets (4, 5) or the fluid outlets. (6, 7), for transporting fluid into and out of each chamber. The invention also relates to a method for pressure exchange between fluids.
