A solar energy large-capacity heat collection and storage system with integrated absorption and storage

Abstract

The invention discloses an absorption and storage integrated solar energy high-capacity heat collection and storage system. The absorption and storage integrated solar energy high-capacity heat collection and storage system comprises a plurality of heliostats, a secondary reflection condenser, a heat storage pool, a heat absorption pool, a multi-hole heat absorber, a water circulating pump and a heat storage pool quantizer, the multiple heliostats are evenly distributed on the left and right sides of the heat storage pool, the secondary reflection condenser is arranged on the heat storage pool, the heat absorption pool is immersed in the heat storage pool, the multi-hole heat absorber is arranged inside the heat absorption pool, and a hot water outlet is formed in the bottom of the heat absorption pool and sequentially connected with the water circulating pump, a tee valve and the heat storage pool quantizer through pipelines. The absorption and storage integrated solar energy high-capacity heat collection and storage system is simple in structure, the heat collection process and the heat absorption and storage process are separated, the fluid pipeline amount of the whole system iseffectively reduced, and fluid pipelines are located inside the heat storage pool, so that the anti-freezing aim of the system is effectively achieved; and meanwhile, a two-loop design and anti-freezing liquid heat transfer fluid are not needed, so that cost consumption in the heat absorption and storage process is greatly reduced, and heat loss of the system pipelines and the occupied space of the whole system are reduced.

Description

technical field [0001] The present invention and the technical field of solar heat collection and storage system, more specifically, relate to a solar energy large-capacity heat collection and storage system integrating absorption and storage. Background technique [0002] Solar heating is a form of solar thermal utilization technology that converts solar energy into heat energy and uses it for building heating and domestic hot water supply. The application of large-scale solar district heating technology is an important way to reduce the consumption of fossil energy in building heating and improve the air quality in the heating season. Solar radiation is affected by fluctuating factors such as day and night changes, seasonal fluctuations, and weather changes. The solar energy flux density is low and requires a large installation area. At the same time, the heating system has seasonal characteristics, and the ambient temperature in northern heating areas is low in winter. q...

Problems solved by technology

[0003] At present, there are different solar heat utilization systems on the market, such as some heat collection and storage systems based on flat plates and vacuum tubes. This kind of system has a lot of overall fluid pipelines, and requires the use of secondary circuit design and antifreeze heat transfer fluid, greatly Increase the cost consumption of the heat absorption and heat storage process. In addition, because there are many pipelines, the heat will be lost during the passage of the pipelines, which greatly reduces the thermal efficiency of the system. The safety of the system cannot be guaranteed due to damage caused by factors such as impact and scaling
