Abstract

A pressure reduction device capable of recycling fluid energy comprises a throttling component, a pressure control mechanism and a turbine. The turbine is installed at the fluid outlet end of the throttling component so that accelerated fluid of the throttling component can impact on an impeller of the turbine after throttling. The impeller rotates under the fluid impact, then a turbine rotor is driven to rotate together, the mechanical energy of the turbine rotor is output through a transmission component or an energy conversion device, and fluid energy recovery is achieved. Meanwhile, the pressure of the fluid is reduced under the fluid resistance action of the throttling component and the turbine. The pressure control mechanism controls the fluid pressure at the fluid outlet end of the turbine by adjusting the opening degree of the throttling component and/or the rotation resistance of the impeller so that the fluid pressure can be kept in an error range of a set value all the time. The accelerated fluid after throttling of the throttling component impacts on the impeller to apply work, more energy is converted into the mechanical energy of the turbine rotor, and thus the fluid energy recovery efficiency is improved. The pressure reduction device is simple in structure and easy to manufacture, wide application is facilitated, and a large amount of energy can be saved.

Description

Technical field [0001] The present invention relates to the field of fluid pressure control and fluid energy recovery, and in particular to a pressure reducing device capable of recovering fluid energy, which can recover fluid energy while decompressing fluid. Background technique [0002] Existing fluid pressure reduction devices mainly use rapid reduction of the flow channel and change the direction of the flow channel to generate turbulence and friction in the fluid to achieve the purpose of consuming fluid energy and reducing fluid pressure. The fluid energy is meaninglessly lost during the decompression process. . At present, although there are devices that can recover fluid energy while decompressing fluids in public information, the existing devices have low energy recovery efficiency. [0003] The State Intellectual Property Office of the People’s Republic of China issued a patent with the announcement number 104040166A on September 10, 2014, which discloses a power genera...
