Description

technical field [0001] The invention belongs to the technical field of solar photothermal utilization in the field of new energy, and is a device capable of concentrating heat and generating electricity at the same time, and the ratio of heat collecting and generating electricity can be automatically adjusted in real time. Background technique [0002] In the field of solar concentrating light and heat utilization, the most commercialized is the trough-type concentrating heat collection device. The trough-type heat collector uses a trough-shaped parabolic mirror to reflect sunlight and gather it on the vacuum heat-collecting tube to heat the medium, and the steam generated is sent to the steam turbine steering gear of the main workshop to realize solar thermal power generation. The outside of the vacuum heat collecting tube used in the trough thermal power station is a cylindrical glass tube shell, and the internal heat collecting core tube runs through the vacuum glass tube...

Problems solved by technology

However, due to the complex manufacturing process of concentrated photovoltaics, high requirements for integrated systems, and high technical difficulties, there are not too many domestic enterprises involved in this field, and the production scale is still small.

[0005] The invention application with the application number CN201610143200 discloses a trough-type solar heat and power cogeneration receiver device. The defect of this design is that although power generation and heat collection are realized at the same time, the collected heat comes from the concentrated light collected by the condenser tube. The waste heat of the solar panels produces low-quality heat; and in this design, the position of the concentrating solar panels is fixed, and the ratio of the generated electricity to the collected heat is constant, and real-time regulation of electricity and heat cannot be realized. and flexible allocation
