Description
Technical field
The present invention relates to the solar energy utilization, particularly sampled point focused solar energy tracking system realizes that this spy generates electricity as the occasion requires and distributed utilization.
Background technology
Solar energy tracking is mainly by three kinds of slot type, tower and butterflies, because the slot type system is that the relative technical difficulty of single-direction tracing is lower, simultaneously because solar energy selects coating and technology in vacuum tube to possess industrialization production capacity in the temperature range of 100-400 degree, thereby can be produced in batches rapidly, be exactly the slot type system by the earliest commercial applications in the world.
The main tracking mode of international slot type system adopts the focal position that a heat exchanger tube is arranged on the slot type system, in heat exchanger tube, charge into conduction oil or directly water is heated to be steam, thereby realize the collection of heat energy by motor-driven conduction oil or flow of steam.Conduction oil motion together in pipeline in the process of tracking solar realizes being connected between the pipeline that moves and the pipe that does not move in the mode of heat conducting oil pipe and outflow end employing bellows; Because bellows needs high temperature resistant, the high requirement of reliability, thereby becomes Primary Component, this kind connection simultaneously can't guarantee the heat insulating ability requirement, thereby the heat waste of system is very high.Simultaneously, the trough type solar power generation system mainly is large-scale solar heat power generation system, its scale power generation amount is 30-100WM, its 1WM power station just needs to take up an area of 60 mu, 100 meters of common every group slot type system head, the wide 5-8 rice of mirror requires prepartion of land degree error less than the 1-3 degree, thereby the requirement of comparison strictness is arranged for the soil.This technology mainly is suitable for large-scale generating, is not suitable for small-scale area applications, particularly is not suitable for carrying out in the city generating of solar energy and thermoelectricity, cold coproduction generating, thereby has limited its application.
Chinese patent 200710176966 provides a kind of tracking system of combination, can be used for slot type, the tracking system of tower combination, the mode of its tracking adopts focal line is motionless and mode that the solar energy mirror system moves, mainly be to adopt two tracks are set on the ground follow the tracks of, and slot type system point focusing system, utilize its linear axes and the parallel placement of earth autobiography axle, thereby the rotation that can adopt a direction realizes following the tracks of, but this scheme adopts rotation on the ground to realize the slot type tracking, obviously can not realize following the tracks of, thereby the inventor further is provided with following in elevation in scheme, the slot type system is not a single-direction tracing just like this, and become two-way tracking, thereby inventor's tracking problem that focus is not moved when not solving the slot type single-direction tracing.
Existing focused solar energy utilizes technology, mainly be to be applied to large-scale generating, the power station of common 1WM, just need 60 mu occupation of land, such occupation of land requires to be difficult in the city and promotes, thereby need provide a kind of solar focusing that is suitable for the urban land requirement to utilize system according to the soil requirement in cities and towns.
