Abstract

The invention relates to a photovoltaic and organic Rankine cycle coupling combined heat and power supply system and belongs to the technical field of energy and environment. The photovoltaic and organic Rankine cycle coupling combined heat and power supply system comprises a heat transfer fluid circulation loop, a biomass burner smoke discharge loop, a heat supply hot water loop and a cooling loop, and further comprises a high temperature stage organic Rankine circulation loop, a low temperature stage organic Rankine circulation loop and a solar cell cooler / organic medium preheater. The high temperature stage organic Rankine circulation loop is connected with the heat transfer fluid circulation loop, the low temperature stage organic Rankine circulation loop is connected with the high temperature stage organic Rankine circulation loop, and the cooling loop is connected with the low temperature stage organic Rankine circulation loop. By adoption of a two-stage overlaid type organic Rankine cycle, the photovoltaic and organic Rankine cycle coupling combined heat and power supply system can achieve gradient heat utilization, greatly lower cost, improve utilization efficiency of energy and photovoltaic power generation efficiency, save materials and cost, and facilitate achievement of an individual distributed power generation system.

Description

technical field [0001] The invention relates to a photovoltaic and organic Rankine cycle coupled heat and power cogeneration system, which belongs to the technical field of energy and environment. Background technique [0002] Electricity production plays an increasingly important role in modern production and life. For a century, the power industry has relied heavily on fossil fuels. Although in recent years, with the application of supercritical Rankine cycle and other technologies, the efficiency of coal power has gradually increased (the latest technology in the world can now reach a thermal efficiency of nearly 50%), but power Industry is still the main emission source of serious environmental pollutants such as carbon dioxide and sulfur dioxide. At the same time, with the depletion of fossil fuels, the cost and difficulty of mining will increase. Therefore, we will increase the development of new energy and reduce our dependence on fossil fuels. , using cleaner energy...
