A dynamically adjustable solar energy concentration and frequency division heat and power cogeneration device and method

Abstract

The invention discloses a solar energy concentrating frequency-division combined heat and power generation device and method capable of dynamically controlling. The solar energy concentrating frequency-division combined heat and power generation device comprises a linear Fresnel reflective mirror array, wherein a rotation shaft capable of dynamically controlling is arranged above the linear Fresnel reflective mirror array, a pair of solid-state frequency-division devices and a pair of total-reflection devices are arranged in a circumferential direction of the rotation shaft, a vacuum tube heatcollector with a built-in heat collection medium is arranged above the rotation shaft, a secondary reflective device is arranged above the vacuum tube heat collector, a hybrid receiver is arranged ateach of two sides of the rotation shaft, a solar cell is arranged in a cavity of the hybrid receiver, a glass baffle plate is arranged at an inner side of the solar cell, and a cooling system is arranged at an outer side of the solar cell. By the solar energy concentrating frequency-division combined heat and power generation device, intelligent regulation of power generation quantity and heat generation quantity is achieved, so that the integral utilization efficiency of solar is substantially improved.

Description

technical field [0001] The invention relates to a solar energy utilization device, in particular to a dynamically adjustable solar energy concentrating frequency division heat and power cogeneration device and method. Background technique [0002] The massive use of traditional fossil energy has not only caused the shortage of fossil energy itself, but also brought great harm to the world environment and posed a serious threat to the living space of human beings. As a renewable and clean energy source, solar energy contains huge energy, and is generally considered to be an ideal new energy source. Solar heat and power cogeneration technology combines solar collectors and photovoltaic modules, which can convert solar energy into electrical energy and heat energy at the same time, thereby improving the comprehensive utilization efficiency of solar energy. [0003] The use of concentrating technology can increase the energy flow density of solar energy, and replace relatively ...
