Problems solved by technology

Chinese patent (CN101821482A) discloses a four-port rotary work exchange device in which the low-pressure inflow liquid flows in a straight line in the stator liquid collection tank. Rely only on high pressure inflow fluid
[0006] U.S. Patent (US6773226) and Chinese Patent (CN101925749A) disclose a work exchanger with a spherical piston in the rotor hole. This design can completely block the contact and mixing between different fluids in theory, but the introduction of the physical piston , not only occupies the space of the channel, reduces the volumetric efficiency of the channel, but also increases the friction and impact between the sliding parts, making the structure complex and poor in reliability, so this structure is difficult to be applied in practice

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0035] see figure 1 with Image 6 , the rotary work exchanger structure with extended inlet angle structure of the present invention includes a rotor 3 with a circular rotor hole 6, an upper stator 2 and a lower stator 4 located at the upper and lower ends of the rotor 3, and a sleeve 9 four parts. The upper stator 2 communicates with the low-pressure liquid inlet 15 and the high-pressure liquid outlet 14 , and the lower stator 4 communicates with the high-pressure liquid inlet 13 and the low-pressure liquid outlet 16 . The upper stator 2 and the lower stator 4 are connected with the rotor 3 through the rotor central shaft 12. The rotor central shaft 12 supports the rotor 3 and is connected with an external motor to drive the rotor to rotate. The rotor central shaft 12 is equipped with mec...

Abstract

The invention discloses a rotary power exchanger with an extended inflow angle structure, and belongs to the technical field of fluid residual pressure recycling. The exchanger comprises a rotor, an upper stator and a lower stator which are positioned at the two ends of the rotor, and a rotor sleeve, wherein the stators are provided with inflow liquid collecting slots with extended angle structures, so that pressure gradient is remarkably reduced when speed is in gradient change in a switching process among a high-pressure communication region, a sealing region and a low-pressure communication region of a duct, and therefore, jet-flow mixing of the liquid can be effectively reduced. The rotary power exchanger disclosed by the invention is reasonable in inflow structure design, simple and convenient to manufacture, and capable of effectively restraining jet-flow mixing in the duct and guaranteeing concentration quality of a first liquid pressurized in a pressure energy transmission process, so that a concentration value at a high-pressure outlet is within a stable range, and the efficient operation of the power exchanger and a membrane system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fluid residual pressure recovery, and relates to a rotary work exchanger for recovering liquid pressure energy, in particular to a rotary work exchanger with an extended inlet angle structure. Background technique [0002] In the process industry, there are a large number of high-pressure fluids with recoverable residual pressure, and their pressure energy can be recovered through work exchangers. According to the working principle, the power exchange device can be divided into two types: turbine type and volume type. [0003] The turbine type work exchanger relies on high-pressure fluid to impinge on the impeller, which is connected to the booster pump through a shaft. The high-pressure liquid energy undergoes secondary conversion of "pressure energy-mechanical energy (shaft work)-pressure energy", and finally transfers the recoverable residual pressure to the low-pressure fluid that needs to be pressur...
