Abstract
(A1) Die vorliegende Erfindung bezieht sich im Bereich der Technik von Umkehrosmoseanlagen auf einen Druckaustauscher sowie eine Umkehrosmoseanlage unter Ausnutzung der Energierueckgewinnung. Des Weiteren betrifft die Erfindung ein Verfahren zum Druckausgleich sowie die Verwendung eines erfindungsgemaessen Druckaustauschersystems.
DE 102009020932 A1 UPAB: 20101208 NOVELTY - The pressure exchanging system comprises first and second pressure tubes (21, 22) with first and second chambers (211, 212), where each first and second chamber is connected with inlet- and outlet line (3a, 30a) for filling the first chamber with a first fluid, and the second chamber with a second fluid and for emptying the chambers. In the interior of two pressure tubes, a technical scraper (210) is arranged, which separates the first and the second chambers of each pressure tube. The volume of the chamber and/or the pressure in the chamber is controllably variable. DETAILED DESCRIPTION - The pressure exchanging system comprises first and second pressure tubes (21, 22) with first and second chambers (211, 212), where each first and second chamber is connected with inlet- and outlet line (3a, 30a) for filling the first chamber with a first fluid, and the second chamber with a second fluid and for emptying the chambers. In the interior of two pressure tubes, a technical scraper (210) is arranged, which separates the first and the second chambers of each pressure tube. The volume of the chamber and/or the pressure in the chamber is controllably variable through the movement of the scraper within each pressure tubes between two turning points by a linear motor on which the scrapers are coupled to each pressure tubes. The scrapers are coupled in two pressure tubes by attachments and/or power- and/or positively locking coupling on the linear-motor. The technical scraper comprises a permanent magnetic material and/or a corrosion-resistant coating, and/or is formed in cylindrical, oval and/or dumbbell- shaped manner. The scrapers are coupled to each other in the first and second pressure tubes. The two pressure tubes consist of stainless steel or glass fiber reinforced plastic. The inlet and outlet line are connected to the first and/or the second chambers with a ball valve and/or a return valve. The scraper is braked in the first pressure tube and the second pressure tube in the area of each return point and/or is subjected on each return point to stop. INDEPENDENT CLAIMS are included for: (1) a reverse osmosis plant; and (2) a pressure exchange process. USE - Pressure exchanging system useful in seawater and brackish water desalination, in the area of waste water treatment, in food industry and in the area of hydraulic high pressure system (claimed). ADVANTAGE - The pressure exchanging system can be simply and economically manufactured.
