Description

A device for recovering residual pressure between streams in different phases

technical field

The invention belongs to the technical field of residual pressure recovery, and relates to a residual pressure energy recovery device, in particular to a residual pressure recovery device between streams in different phase states.

Background technique

There are a large number of high-pressure fluids in the field of energy and chemical industry, and the considerable residual pressure energy contained in them is usually released directly through the pressure reducing valve in the process, resulting in a large amount of energy loss. In some occasions, the residual pressure of the fluid can be used to pressurize fluids in different phases, so that the residual pressure energy of the fluid can be fully utilized, and the power consumption and production cost of the system can be greatly reduced.

The existing Chinese patent (CN102865259A) discloses a pressure exchanger, which uses high-pressure fluid to directly contact and pressurize low-pressure fluid, and uses the tangential impact force of high and low-pressure water flow as the power to rotate the rotor. The clearance fit with the end cap controls the leakage. The device can only recover the residual pressure between the liquid streams, and the processing capacity of a single machine is small, the structure is relatively complicated, the processing and installation precision are high, and there is a phenomenon of mixing between fluids.

The existing Chinese patent (ZL201020150791.3) discloses a piston-type gas power exchange device, which is driven by a flywheel and a motor to directly recover power from a high-pressure gas stream. This device can only recover the residual pressure between the gas streams, and has a complex structure, many moving parts, and serious wear between the parts, and the addition of motor auxiliary propulsion requires additional power consumption.

The existing residual pressure energy recovery equipment is limited to the residual pressure recovery equipment between streams in the same phase state. For the above two residual pressure recovery devices, the former can only recover residual pressure between liquid media, and the latter can only recover residual pressure between gas media. This brings great limitations to the application of residual pressure recovery technology.

The operating principle of the residual pressure recovery device between different phase streams of the present invention is:

On the left side, high-pressure liquid enters the left chamber 11 from the high-pressure inlet hole 3, and the liquid pressure acts on the slide plate 6. At the same time, the high-pressure stream washes the slide plate 6, pushes the slide plate 6 to move, and drives the rotor 5 to rotate, and the slide plate 6 It can slide in the rotor channel 7, and cling to the inner surface of the cylinder 1 under the action of centrifugal force, and the liquid flows to the low-pressure outlet hole 10 to be discharged, that is, the left chamber 11 can realize the conversion of the pressure energy of the fluid into the rotor 5 and the sliding vane 6 kinetic energy; on the right side, the gas enters the right chamber 8 from the low-pressure inlet hole 9, the rotor 5 rotates to drive the sliding plate 6 to move, and the sliding plate 6 pushes the fluid to flow in the right chamber 8. With the change of the cavity, the working The cross-sectional area of the cavity first increases and then decreases, corresponding to the gas suction process and compression process, the pressure of the gas increases after compression, and the gas is discharged from the high-pressure outlet hole 4 after the gas is pressurized, that is, the right chamber 8 can realize the rotor 5 and The kinetic energy of the slide plate 6 is converted into the pressure energy of the fluid. In general, the energy conversion path is: the pressure energy of the high-pressure liquid - the kinetic energy of the rotor 5 and the sliding vane 6 - the pressure energy of the low-pressure gas. Through the residual pressure recovery equipment between the streams in different phases, the pressurization of the high-pressure liquid is realized. The process of low-pressure gas realizes the recovery and reuse of fluid residual pressure.

In summary, the residual pressure recovery equipment between streams in different phases disclosed by the present invention includes a cylinder body, a rotor, and a sliding vane.

The linear main curve section of the cylinder in the left chamber is arc-shaped, through which the liquid medium passes, and the inlet and outlet holes are streamlined channels; The orifice is also a streamlined channel.

The molded line of the inner cavity of the cylinder is composed of several circular arc sealing sections, quintic curve transition sections, circular arc main curve sections, and ellipse main curve sections, and the two adjacent curve sections are second-order continuous. Similarly, when the transition curve segment is a seventh-degree curve, the third-order continuity between two adjacent curves can be realized; when the transition curve segment is a ninth-degree curve, the fourth-order continuity between two adjacent curves can be realized, etc. . The higher the degree of the curve in the transition section, the higher the continuity of the profile line can be achieved, the wear between the slide plate 6 and the cylinder body 1 can be reduced, the force condition of the slide plate 6 when sliding can be improved, and the working noise when the equipment is running can be reduced .
