ORC low-temperature electricity generation coupling MVR heat pump evaporation structure

Abstract

The invention provides an ORC low-temperature electricity generation coupling MVR heat pump evaporation structure and belongs to the technical field of energy conservation and consumption reduction. The ORC low-temperature electricity generation coupling MVR heat pump evaporation structure comprises an MVR heat pump evaporation mechanism and an ORC low-temperature electricity generation mechanism.The MVR heat pump evaporation mechanism and the ORC low-temperature electricity generation mechanism are coupled, thus steam produced by the MVR heat pump evaporation mechanism can be utilized by theORC low-temperature electricity generation mechanism, electric energy produced by the ORC low-temperature electricity generation mechanism can be supplied to a compressor in the ORC low-temperature electricity generation mechanism to be used, sensible heat and latent heat in the whole system can be fully utilized, the energy secondary utilization rate is high, thermodynamic utilization efficiencyis improved, and project cost is lowered effectively. In addition, an organic working medium is adopted for the ORC low-temperature electricity generation mechanism, the organic working medium in theORC low-temperature electricity generation mechanism is in closed circulation, resources are recycled, operation cost is further lowered, and production and development of an enterprise are facilitated better.

Description

technical field [0001] The present invention relates to the technical field of energy saving and consumption reduction, in particular to an ORC (English: Organic Rankine Cycle; Chinese: Organic Rankine Cycle) low-temperature power generation coupling MVR (English: mechanical vapor recompression; Chinese: steam mechanical recompression technology) heat pump evaporation structure. Background technique [0002] Since high-purity products can be obtained in the separation process of chemical products, separation by evaporation is the main method in the ternary industry, and during the operation of the system, system energy consumption, equipment investment and operation will all affect the project cost. However, since the evaporation method is an operation process with high energy consumption, the separation of chemical products by the evaporation method currently used increases the project cost, which is not conducive to the production and development of the enterprise.
