Description

The tower solar-thermal generating system of the many heat collectors of single column formula

Technical field

The present invention relates to a kind of single column formula tower solar-thermal generating system of many heat collectors, belong to Application of Solar Energy field.

Background technology

Solar light-heat power-generation is to utilize large scale array parabolic or dish minute surface to collect solar thermal energy, passes through heat-exchanger rig Steam is provided, in conjunction with the technique of tradition steam turbine generator, thus reaches the purpose of generating.Relative to other emerging energy technology, Solar light-heat power-generation avoids the upstream components technique (such as crystal silicon) of costliness, production procedure energy-conserving and environment-protective, greatly reduces too Total social cost that sun can generate electricity, and the water of burn-out can be stored in huge container, remains able to after the sun sets Drive turbine generator.In general, solar light-heat power-generation form has slot type, tower, dish-style (disc type), linear Fresnel formula four The system of kind.

Tower solar-thermal generating system is to focus in tower by the solar energy ray absorbed, to heat transfer operation material heat into And a kind of concentration solar generating technology generated electricity.Condenser system is by the heliostat of many biaxial solar tracing systems and centralized Thermal tower is constituted.It is characterized in that heat accumulation scheme is simple, pipeline is short, focusing ratio is high, operating temperature higher (up to 800~1000 DEG C), Its annual generating efficiency can reach 17%~20%, higher than slot type.Tower solar-thermal generating system is research at present and application Focus, existing tower solar-thermal generating system can be divided into the most tower and modularity is tower.

There are some problems in the most extensive tower solar-thermal generating system:

1, centralized thermal tower is provided with a heat collector, and advantage is low cost, but heat collector once goes wrong, and needs During maintenance, the stable operation in whole power station then it cannot be guaranteed that.

2, the heat-transfer working medium of heat collector commonly uses device of working medium or fused salt working medium: the heat transfer of (1) single device of working medium, the advantage of heat accumulation are Simple in construction, reliable operation, shortcoming is High Temperature High Pressure operating environment, and energy storage technology difficulty is big.(2) single device of working medium heat transfer, fused salt The advantage of heat accumulation is that tower structure is simple, fused salt is not required to tower;Water is nontoxic, corrosivity is little, be prone to transport;Steam generation technique is applied Relative maturity;The cost of investment of heat-transfer working medium is low.Shortcoming is that water vapour heat transfer coefficient is little, and thermal capacity is low, and energy-flux density is little, thermal-arrest Device efficiency is low relative to fused salt heat collector;The high pressure characteristics of water vapour, to heat collector and the pressure performance requirement of accessory structure part Height, collecting system cost is high;Energy-storage system needs secondary heat exchange, increases heat loss.(3) single fused salt refrigerant heat transfer, heat accumulation are many One conversion links, causes thermal losses.

Modularity tower design can realize quickly designing, Fast Installation, and extensibility is extremely strong, even if some collection thermal tower Breaking down or need to safeguard, properly functioning on whole power station does not results in the biggest impact yet, solves power station stable operation Problem, but use multitower pattern set up tower power station land occupation area bigger.Reduce cost the most to greatest extent, carry High generation efficiency becomes the study hotspot of tower power station.

At present, yet there are no the relevant report of single column formula many heat collectors tower power station.
