Novel organic Rankine cycle power generation system adopting falling film evaporator

Abstract

The invention relates to a novel organic Rankine cycle power generation system adopting a falling film evaporator. The novel organic Rankine cycle power generation system comprises a preheater, the falling film evaporator, a gas-liquid separator, an expander, an electric generator, a heat regenerator, a liquid storage device, a working medium pump and a condensing treatment device; the condensingtreatment device comprises a condenser, a water suction pump and water body purification equipment; the water suction pump, the water body purification equipment and the condenser are sequentially connected through a cycle pipeline; and the preheater and the falling film evaporator are connected in series and both connected with a heat source. Through the technical scheme, the problems that in theprior art, an organic Rankine cycle power generation system adopting the falling film evaporator is poor in overall heat exchange effect, large in heat exchange area of the evaporator, and high in cost, when a cooling tower is adopted to cool a working medium body, the cooling effect is poor, and power consumption and water consumption are large can be solved.

Description

technical field [0001] The invention relates to the technical field of low-temperature power generation, in particular to a novel Organic Rankine Cycle (ORC) power generation system using a falling film evaporator. Background technique [0002] Energy shortage and environmental pollution have developed into worldwide problems. Energy conservation, emission reduction, reduction of energy consumption, and improvement of comprehensive utilization of energy are the fundamental ways to solve energy problems. [0003] The organic Rankine cycle is a Rankine cycle in which low-boiling point organic matter is used as a working medium. In the prior art, the organic Rankine cycle power generation system using a falling film evaporator, because the organic working medium fluid at the outlet of the working medium pump has tens of K If the supercooled liquid directly enters the falling film evaporator to evaporate, some heat exchange tubes will be fully sensible heat exchange, and some he...
