Organic Rankine cycle power output device with space heat regenerator

Abstract

The invention relates to an organic Rankine cycle power output device with a space heat regenerator. Exhaust air after expansion of a pneumatic motor and a liquid cold working medium are fully mixed in a working process, energy of the exhaust air is recycled, the mixed liquid working medium is introduced into a working medium pump to be pressurized and is then discharged out of the working medium pump to continuously absorb the energy, and next cycle is performed. The organic Rankine cycle circular power output device with a space heat regenerator has the beneficial effects that the arrangement manner that an expansion machine, a heat regenerator, a condenser and the working medium pump are serially connected in the traditional organic Rankine cycle is changed into a connecting manner of the expansion machine, the space heat regenerator and the working medium pump, the expansion machine and rotors of the working medium pump are coaxial, in this way, the energy of the exhaust air can be recycled, and cycle efficiency is improved, such that the arrangement of an evaporator and the condenser is more free, the freedom degrees of working condition adjustment are more, the number of parts is reduced, and compactness of the parts is increased.

Description

technical field [0001] The invention belongs to the technical field of organic Rankine cycle heat energy utilization, and in particular relates to the development of an organic Rankine cycle power output device with space recuperation. Background technique [0002] In recent years, energy shortage has become the focus of restricting social development. As a big energy consumer, my country's energy utilization rate is far below the world's advanced level. Under such circumstances, the low-quality thermal energy that has been neglected in the past has attracted more and more attention, and the organic Rankine cycle has become more and more popular as a promising low-quality energy utilization technology. [0003] However, the structure of the organic Rankine cycle system is very limited in the actual application process. Taking the organic Rankine cycle for vehicles as an example, an overly complex system layout will not only occupy the already tight space, but also bring ad...
