Distributed solar point focusing optical mirror heat pipe tracking and utilizing system

Abstract

The invention aims to provide a distributed solar point focusing optical mirror heat pipe tracking and utilizing system, which can be arranged in a distributed manner based on land conditions in urban regions, at least one solar heat pipe system, a solar tracking system, a point focusing solar mirror and a tracking bracket are combined to form a group of solar point focusing utilizing system, multiple groups of solar point focusing utilizing systems are distributed in different areas, and multiple groups of solar heat pipe systems can be mutually connected to jointly form the solar point focusing utilizing system. By changing the array code of the existing trench type solar system into a distributed mode, the trench type solar utilizing technology is led to be applicable to different areas and cities, thus reducing requirements and limitations thereof on field, facilitating integrated applications in different areas and buildings, widening the utilization type and mode of solar energy, and leading various solar energy used thereby available.

Description

technical field [0001] The invention relates to the utilization of solar energy, especially the tracking utilization of solar energy focused on sampling points and its distributed utilization. Background technique [0002] Solar tracking mainly consists of three types: trough type, tower type and butterfly type. Because the trough type system is one-way tracking, the relative technical difficulty is relatively low. At the same time, due to the solar energy selective coating and vacuum tube technology, it has industrial production in the temperature range of 100-400 degrees. Therefore, it can be mass-produced quickly, and the earliest commercial application in the world is the trough system. [0003] The main tracking method of the trough system in the world is to set a heat exchange tube at the focal point of the trough system, fill the heat exchange tube with heat transfer oil or directly heat water into steam, and the motor drives the heat transfer oil or steam to flow In...

This technology is mainly suitable for large-scale power generation, not suitable for small-scale regional applications, especially not suitable for solar power generation and cogeneration power generation in cities, thus limiting its application

[0004] Chinese patent 200710176966 provides a combined tracking system, which can be used in a trough-type and tower-type tracking system. The tracking method adopts the method of keeping the focal line fixed while the solar mirror system moves, mainly on the ground. Two orbits are set for tracking, and the trough system point focusing system uses its linear axis to be placed parallel to the earth's autobiographical axis, so it can use rotation in one direction to achieve tracking, but this scheme uses rotation on the ground to achieve trough tracking , obviously tracking cannot be realized, so the inventor further set pitch tracking in the scheme, so that the trough system is not a one-way tracking, but a two-way tracking, so the inventor did not solve the tracking problem that the focus does not move when the trough one-way tracking question

[0005] The existing focused solar energy utilization technology is mainly applied to large-scale power generation. Usually, a 1WM power station requires an area of ​​60 mu. Such an area requirement is difficult to promote in cities, so it needs to be based on the land requirements of cities , to provide a solar energy concentration utilization system suitable for urban land requirements
