Solar distributed point focusing optical lens tracing vacuum tube utilizing system

Abstract

The invention aims to provide a solar distributed point focusing optical lens tracing vacuum tube utilizing system. For realizing distributed arrangement according to land conditions in urban areas, a set of solar point focusing utilization system is formed by at least one vacuum tube utilization device, a solar tracing system, a point focusing solar mirror and a tracing support, a plurality of sets of solar point focusing utilization systems are arranged in different areas, and a plurality of groups of vacuum tube utilization devices can be connected with one another to form the solar point focusing utilization system. In the invention, due to the change of the array mode of the conventional slot type solar system into a distributed mode, a slot type solar utilization technique of the solar is suitable to be used in different areas and cities in combination with buildings in these different areas conveniently with fewer requirements and limitation on land, and a new solar utilization type and mode is provided for various kinds of solar utilization.

Description

Technical field [0001] The invention relates to the utilization of solar energy, in particular to linear tracking with a straight line in the focus tracking of solar energy and its distributed utilization. Background technique [0002] Solar tracking is mainly divided into three types: trough, tower and butterfly. Because the trough system is one-way tracking, the technical difficulty is relatively low. At the same time, due to the solar selective coating and vacuum tube technology, it has industrial production in the temperature range of 100-400 degrees. Capability, which can be quickly mass-produced, and the first commercial application in the world is the trough system. [0003] The main tracking method of the international trough system is to set a heat exchange tube at the focal position 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 So as to realize the co...

Problems solved by technology

[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
