A sliding vane type residual pressure recovery device

Abstract

The invention discloses sliding sheet type overpressure recovery equipment and belongs to the technical field of overpressure recovery. According to the sliding sheet type overpressure recovery equipment, main curved sections of cylinder profile lines in left and right cavities are in an arched shape; flow inlets and outlets are streamline pore channels; a cylinder inner cavity profile line is formed by connecting an arched sealing section, a curve transition section with an arched main curve section; and two adjacent curves are in a second order continuous manner. When being bilaterally symmetric mold cavities, working cavities can be applied to treating the working condition of same stream flow on the two sides; when being the mold cavities without bilateral symmetry, the working cavities can be applied to treating the working condition of different stream flows on the two sides. The sliding sheet type overpressure recovery equipment has a simple structure, is little in mixing fluids and lower in requirement for processing installation accuracy and can be applied to treating the working conditions of same or different flows on the two sides. Through the sliding sheet type overpressure recovery equipment, the overpressure of high-pressure, pressurized and low-pressure fluids are recycled and reused and has important significance of lowering system energy consumption and production cost and promoting energy conservation and emission reduction.

Description

technical field

[0001] The invention belongs to the field of residual pressure recovery equipment, and relates to a residual pressure energy recovery device, in particular to a sliding vane type residual pressure recovery device. Background technique

[0002] 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. Efficient recycling of excess pressure energy can greatly reduce system energy consumption, reduce production costs, and effectively solve the problem of excess pressure energy waste in the energy and chemical industry.

[0003] 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-pr...
