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 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 sche

Abstract

The invention aims at providing a solar distributed point-focusing solar lens tracking system and application thereof. The solar distributed point-focusing solar lens tracking system can be distributed and arranged according to the land conditions of a city region, therefore one group of solar point-focusing utilization systems consists of at least one solar utilization equipment, a solar tracking system, a point-focusing solar lens and a tracking bracket; a plurality groups of solar point-focusing utilization systems are distributed in different regions; and a plurality groups of solar utilization equipment can be mutually connected to form each solar point-focusing utilization system together. The invention can enable the solar slot type solar utilization technology to be suitable for different regions and cities by changing the array mode of the traditional slot type solar system into a distribution mode, thereby lowering the requirements and the limitation for fields; the invention can be conveniently used in different regions and for building integration and also widens the kinds and the modes of solar utilization, thereby being capable of carrying out multiple solar utilizations.

Description

technical field [0001] The invention relates to the utilization of solar energy, especially the tracking of focus of solar energy focus tracking 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 order to reali...
