Solar energy distributed linear solar optical lens tracking system and application

Abstract

The invention aims to provide a solar energy distributed linear solar optical lens tracking system which can be arranged in a distributed mode according to land conditions of urban regions and application. A group of solar linear utilization system consists of at least one solar utilization device, a solar tracking system, a linear solar optical lens and a tracking bracket; and a plurality of groups of solar linear utilization systems are distributed in different regions, and a plurality of groups of solar utilization devices can be interconnected together to form the solar linear utilization system. The array mode of the conventional trench type solar system is changed into a distribution mode, so that the solar trench type solar utilization technology is suitable for different regions and cities and is convenient to apply to different regions and integrated buildings, the requirement and limitation of the technology on places are reduced, the types and modes of solar utilization are broadened at the same time and various solar energies can be utilized.

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to the linear tracking in which the focusing tracking focus of solar energy is a straight line 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 line position of the trough system, fill the heat exchange tube with heat transfer oil or directly heat water into steam, and the heat transfer oil...

Problems solved by technology

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 combined tracking system. The tracking method adopts the method of keeping the focus fixed while the solar mirror system moves. It is mainly set on the ground. Two orbits are used for tracking, and the line-focusing system of the trough system uses its linear axis to be placed parallel to the earth's self-propagation 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 one-way tracking, but two-way tracking, so the inventor did not solve the problem that the focal line 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
