Multi-heat source coupled organic Rankine cycle (ORC) power generation and heating system

Abstract

The invention provides a multi-heat source coupling organic rankine cycle (ORC) power generating and heat-supplying heating system. The multi-heat source coupling ORC power generating and heat-supplying heating system is characterized in that five subsystems are included, the five subsystems are the multi-heat source coupling system (1), the water tank regulating system (2), the ORC power generating system (3), the heat-supplying system (4) and the heating system (5); heat-working media are conveyed in the water tank regulating system (2) through a pipeline by the multi-heat source coupling system (1), after the heat-working media are converged in the water tank regulating system (2) and the temperature is regulated, the heat-working media enter the ORC power generating system (3), the heat-supplying system (4) and the heating system (5); and the heat-supplying system (4) is connected with the heating system (5) in parallel. Three heat sources are coupled at the same time, the three heat sources are solar energy, gas boiler energy and geothermal energy; according to the specific requirement condition of user terminals, the heat-working media can be reasonably distributed through the water tank regulating system to realize heat and power cogeneration; and the multi-heat source coupling ORC power generating and heat-supplying heating system has the advantages that cost is low, construction is easy, multi energies are complemented, and running efficiency is high.

Description

technical field [0001] The invention relates to a multi-heat source coupled Organic Rankine Cycle (ORC) power generation and heating system, which belongs to the technical field of energy utilization. Background technique [0002] With the rapid development of the economy, the demand for energy in human society has risen sharply. At present, in the field of energy utilization technology, the energy consumption structure is relatively simple. Most energy development and utilization systems often use a single heat source to provide power generation or heating services for users. The overall energy utilization efficiency is low and causes a series of environmental pollution problems. It cannot meet people's requirements and is contrary to the realization of human sustainable development goals. [0003] As people pay more and more attention to energy security issues, related low-temperature waste heat recovery technologies have emerged one after another, and are gradually appli...
