Power switching network implementation method based on wave rotor equipment

Abstract

The invention discloses a power switching network implementation method based on wave rotor equipment, and relates to the technical field of engineering energy conservation. Pressure energy is directly transmitted through unsteady gas waves, expansion cooling of public engineering steam and the work exchange process of high-pressure steam and low-pressure steam are achieved, a flexible and diversified public steam work exchange network is formed with the assistance of a high-expansion-ratio injection supercharger, and the energy-saving purpose is achieved; the wave rotor and the jet pressurizer are arranged in different forms according to working characteristics, so that the functions of an expansion cooling process of high-pressure steam, a pressurizing and warming process of low-quality steam, a work exchange process of high-pressure steam and low-pressure steam and the like are realized, and external shaft work does not need to be consumed; the practical problems of current industrial pressure reduction, temperature reduction pressure energy loss and low extra steam production amount are solved, the sustainable development principle is met, and energy consumption reduction of an industrial process device is facilitated.

Description

technical field [0001] The invention relates to the technical field of engineering energy saving, in particular to a method for realizing a power exchange network based on a wave rotor device. Background technique [0002] In the whole social production, the energy consumption of the process industry accounts for a considerable part; steam plays a vital role in the process industry, and the efficient use of steam is an important improvement means for traditional industries to achieve the goal of carbon neutrality in my country. In process system engineering, the comprehensive technology of heat exchange network is relatively mature and widely used; however, for low-quality steam with gauge pressure less than 1 bar, a condenser is usually used to recover soft water, resulting in a waste of pressure energy; Decompression, usually using a temperature reduction and pressure reduction device composed of throttling and nozzles to achieve the purpose of use, resulting in huge waste...
