Middle and low temperature combined circulation based on Brown circulation

Abstract

The invention discloses a middle and low temperature combined circulation technique based on Brown circulation. The utilization of the huge heat quantity released by the heat of condensation of heat-engine plants and nuclear power plants is solved. The invention provides a technique adopting a heat absorption type heat pump, a loop heat pipe, injection pressurization and an injection circulation system, and the key technical problem of recovering and recycling the residual heat of the condensation is solved. The middle and low temperature combined circulation technique has the advantages that: 1, the concept of gradient utilization is introduced to a chemical energy stage and a stage of converting chemical energy into physical energy, so as to achieve the comprehensive gradient utilization of the chemical energy and the physical energy; 2, the middle and low temperature combined circulation is a multifunctional comprehensive novel thought, and the obstruction of improving heat force and environmental protection performance caused as independent circulation systems develop respectively are broken, so as to achieve the organic combination of the circulation systems using different energies; and 3, the middle and low temperature combined circulation is a breakthrough point for seeking key techniques, materials, working substances and the like, so as to achieve the higher-level integration of the circulation systems.

Description

[0001] Technical fields: thermal and nuclear power generation, cogeneration of heat and power, distributed cogeneration of heat, power and cooling, coal-based polygeneration technical background: [0002] (I. Introduction [0003] Over the past 100 years, engineering thermodynamics has penetrated into various disciplines and technical fields and formed many new sub-disciplines. However, its main research objects are still the law and method of converting thermal energy into mechanical energy and the way to make the heat engine convert heat energy into work more effectively, and the main fields involved are still energy and power. Therefore, the thermodynamic cycle used to realize the closed process of thermal energy and mechanical energy conversion has always been the focus of engineering thermodynamics research, especially the research on new thermodynamic cycles and corresponding new working fluids has become an eternal research direction. [0004] For a long time, the pio...

Problems solved by technology

However, conventional ejector pressurization still cannot meet the requirements of various fields, such as the development of some important military equipment, the recovery of a large amount of crude oil gas in oil fields (light hydrocarbon recovery), etc., the existing ejector technology should be applied to In these areas, there are two fatal deficiencies: one is that the pressure loss at the inlet and outlet of the system is too large, which cannot meet special needs; the other is that the multi-stage system must lead part of the medium from the inter-stage, which does not meet the requirements
