An integrated energy-saving water intake device for a large solar thermal storage pool

Abstract

The invention discloses an integrated energy-saving water intake device for a large-scale solar thermal storage pool, which comprises a thermal storage pool. The side of the thermal storage pool is provided with a hot water pipe for an inlet pool, a cold water pipe for an outlet pool, a heating return pipe, a water replenishment pipe and a sewage discharge pipe. A top cover is installed on the top of the heat storage pool, and a water intake tank is provided on the top cover, and a dust cover is installed on the water intake tank; an energy-saving water fetcher is installed in the heat storage pool, and the energy-saving water fetcher includes a movable connection in the axial direction. And the fixed round pipe with gradually increasing inner diameter, more than one intermediate round pipe and water intake round pipe, wherein, the two ends of the fixed round pipe and the middle round pipe are transparent, and the fixed round pipe is installed on the dust cover through the fixing frame, The upper end of the fixed round pipe is connected with the hot water supply pipe of the pool provided through the dust-proof cover; a gear drive mechanism is installed in the dust-proof cover. The invention overcomes the shortcoming of the traditional heat storage pool that the temperature of the water supply fluctuates due to the instability of solar energy, and ensures the stability of the water intake temperature.

Description

technical field

[0001] The invention relates to the technical field of solar heat utilization, in particular to an integrated energy-saving water intake device for a large-scale solar water storage pool, which mainly solves the problem of directional water intake in a heat storage pool. Background technique

[0002] The thermal utilization of solar energy is inseparable from solar heat storage technology, in which the heat storage volume is relatively large, and the charge and discharge cycle period is relatively long (usually one year), which is called seasonal heat storage (long-term heat storage). Studies have shown that heat storage efficiency is related to heat storage volume. Using a larger heat storage volume can properly reduce heat storage temperature, improve collector efficiency, and reduce heat loss. Therefore, large-scale solar heat storage pools (with a volume of more than 200 cubic meters) are usually used for large-volume heat storage to improve the utilizati...
