Rankine-cycle-based vortex disc engine system

Abstract

The invention relates to a Rankine-cycle-based vortex disc engine system which is provided with a closed circulating loop formed by connecting a steam generator, a pressure regulating valve, a vortex disc engine, a condenser and a liquid return pump; the circulating loop is filled with a working medium; a vortex disc engine comprises a shell with an air flow inlet and a vortex disc plate group which is installed in the shell and is driven to rotate by air flow, and the air flow inlet is communicated with the pressure regulating valve; the outermost layer of disc plate of the vortex disc plate group is a thick disc plate, and the middle part of the thick disc plate is connected towards the outer side to form a rotation shaft of the vortex disc plate group and is installed on the shell through a sealing bearing; and one end of the rotation shaft is taken as a power output end, and the other end of the rotation shaft is taken as a steam exhaust outlet to be communicated with the condenser. In the system, a Rankine cycle is taken as a basic principle, the inner liquid work medium is vaporized to form high-pressure steam through the steam generator, and the steam enters the vortex disc engine to act after pressure adjustment to convert steam potential energy into engine kinetic energy to be output, and the exhaust steam is condensed into liquid through the condenser and is sucked and returned to the steam generator through the liquid return pump, therefore, cycle operation is realized.

Description

Technical field: [0001] The invention relates to the technical field of engine equipment, in particular to a scroll engine system based on the Rankine cycle. Background technique: [0002] The Rankine cycle refers to a practical cycle process using water vapor as a refrigerant, mainly including isentropic compression, isobaric condensation, isentropic expansion, and an isobaric endothermic process. It can be used for heating or cooling. Its working process usually includes: [0003] 1. In the water pump, the water is compressed and boosted. During the process, the flow through the water pump is relatively large. The heat dissipation of the water pump to the surrounding is equivalent to the unit mass of working fluid, which can be ignored. Therefore, this process is simplified to a reversible adiabatic compression process, that is, isentropic Compression process. [0004] 2. The process of water being heated in the boiler is originally carried out under the condition of a ...

Problems solved by technology

This type of engine has a complex structure and high design and production costs. Moreover, the combustion is carried out in a relatively narrow space, and the adequacy of combustion is greatly limited. It still has a very high temperature, and it is directly discharged without recycling, which also causes great pollution to the environment. This is also one of the reasons why automobile exhaust has become the largest source of environmental pollution.
