Embodiment 1

[0013] control figure 1 It can be seen that, in the heat pipe type spherical dish type solar energy concentration and heat collection system of this embodiment, the spherical reflector 4 is supported on the sunlight tracking device through the bracket 3 . A heat pipe type vacuum heat collecting tube 6 is placed at the light concentrating cone formed after the spherical reflector 4 is focused. Since the bottom of the concentrating cone formed by the spherical reflector 4 is close to the surface of the reflector, the end of the heating section of the heat pipe vacuum heat collecting tube 6 is placed here, and the optical characteristics of the spherical reflector are rationally utilized, and the structure is compact, and the heat pipe The diameter of the vacuum heat collecting tube 6 heat pipes is equal to (or greater than) the diameter of the conical bottom of the concentrating cone, and the length of the heating section is equal to (or greater than) half of the spherical radiu...

Abstract

The present invention relates to a heat pipe type spherical disc type solar energy light and heat collector, belonging to the solar energy heat collection establishment technical field, which includesa spherical reflecting mirror disposed on the solar energy optical tracker system and a steam drum supported above the reflecting mirror. The steam drum is made up of an inlet and an outlet and stored up with working medium. A heat pipe type vacuum heat collecting pipe is arranged on the focusing part of the spherical reflecting mirror. The heating zone of the heat pipe type vacuum heat collecting pipe is positioned on the condensing wimble of the spherical reflecting mirror. The cooling zone of the heat pipe type vacuum heat collecting pipe is inserted into the working medium of the stream drug. The invention has simple technology, low cost, scientific design and easy to generalization and application. It has been found that the invention has fast tempera the rise, excellent heating effect, high efficiency, suitable for large scale industrialization production, secure and reliable performance.

Description

technical field [0001] The invention relates to a solar energy concentrating and heat collecting system, in particular to a solar energy concentrating and heat collecting device applied in a thermal power generation system, belonging to the technical field of solar heat collecting. Background technique [0002] Dish solar thermal power generation system is a more advanced solar power generation system. The system uses a rotating parabolic mirror to concentrate the incident sunlight on the focal point, so that the solar receiver placed at the focal point collects high-temperature heat energy, heats the working fluid, and then drives the generator set to generate electricity. According to the applicant's knowledge, at present, the foreign system adopts the solar Stirling power generation device directly placed at the focal point to generate electricity. blockade. [0003] The search found that in recent years, domestic solar energy utilization is mainly concentrated on vario...
