Embodiment Construction

[0029] Figure 1 to Figure 8 A pressure exchanger 10 is shown for transferring pressure from a high pressure fluid to a low pressure fluid. The pressure exchanger 10 includes a housing 12 and a rotor 14 disposed inside the housing 12 for rotation. By connecting port 16 at one end of the pressure exchanger 10 to relatively high pressure (before pressure exchange) fluid and connecting port 16 at the opposite end of the pressure exchanger to relatively low pressure (before pressure exchange) fluid In a connected manner, the pressure exchanger 10 is used. By rotation of the rotor 14 within the housing 12, pressure is transferred from the high pressure fluid to the low pressure fluid.

[0030] The rotor 14 has a plurality of channels 18 extending substantially axially through the rotor 14 . Each channel 18 has a first opening 20 at one end of said channel 18 (see Figure 5 ), and has a second opening 22 at the other end of the passage 18. The openings 20, 22 are spaced apart f...

Abstract

A pressure exchanger for transferring pressure from a high pressure fluid to a low pressure fluid, including a housing and a rotor arranged for rotation within the housing, the rotor having at least one passage extending generally axially through the rotor, the passage having a first opening at one end and a second opening at another end, the openings being mutually spaced along the length of the rotor, the housing having a plurality of ports at one axial portion for communication with the first passage opening and a plurality of ports at another axial portion for communication with the second passage opening, wherein the first passage opening is directed substantially radially such that fluid is directed radially inwardly when entering the first passage opening and radially outwardly when exiting the first passage opening.

Description

technical field [0001] The present invention relates to a pressure exchanger, and more particularly, but not exclusively, to a pressure exchanger having improved efficiency and / or reduced production costs. Background technique [0002] The use of pressure exchangers is well known in the reverse osmosis process used in the water desalination industry, in particular in the seawater reverse osmosis desalination industry. For example, US Patent No. 7,251,557 discloses a rotary positive displacement pressure exchanger. [0003] However, the applicant of the present application has demonstrated that existing rotary positive displacement pressure exchangers are expensive and not suitable for fluids passing through said pressure exchangers containing a relatively high proportion and relatively large size of particulate material condition. [0004] Embodiments of the present invention seek to provide a pressure exchanger that overcomes or at least alleviates one or more of the prev...
