Abstract

The invention relates to a compressor with an energy recovery device and a power system. The compressor comprises a bypass pipeline, wherein the bypass pipeline is used for returning part of backflowgas of an exhausting port to a gas inlet of the compressor. The compressor also comprises the energy recovery device, wherein the energy recovery device is used for utilizing the backflow gas in the bypass pipeline to generate power and providing the power to the compressor so as to reduce the electric energy loss of the compressor. The power system adopts the compressor with the energy recovery device. The energy of high-pressure backflow gas in the bypass pipeline can be recovered, and the compressor has a better energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to a compressor with an energy recovery device and a power system. Background technique [0002] A reciprocating compressor is a general-purpose chemical mechanical equipment, which belongs to a volumetric compressor. It provides static pressure for other equipment by sucking and discharging a certain volume of gas into the packaging space in sequence. Because the reciprocating compressor has the advantages of high discharge pressure and good stability, it is widely used in the chemical industry. [0003] In practical applications, the displacement of large reciprocating compressors is generally designed according to the maximum volume flow required by the device, that is, there is a certain margin between the maximum volume flow and the volume flow in actual use. However, in the actual production process, the displacement of the reciprocating compresso...
