Heating system using solar energy and heat stored by fused salt

Abstract

The invention discloses a heating system using solar energy and heat stored by fused salt. A large-area solar heat collector and a high-capacity heat preservation water storage tank are used for storing solar heat energy; by the adoption of the characteristic that salt fusing liquid is high in heat storage density within a unit volume and the full use of valley low-price power at night for storing the heat energy, the heating system adopts a static salt fusing tank and an electric heater to directly heat the salt fusing liquid in the salt fusing liquid; by virtue of a method for indirect heat exchange through a heat insulation layer, the salt fusing liquid is more convenient and safer to heat, and the manufacturing cost is extremely low; a super-audio sensing heating unit is used as an auxiliary heater for heating; the super-audio sensing heating unit automatically adjusts the heating power according to the water temperature, so that the heating speed is high, and the heat efficiency is high. The heating system using solar energy and heat stored by the fused salt makes use of the solar energy, adopts the fused salt to store the valley low-price electric energy and adopts a high-efficiency and energy-saving super-audio sensing heating technology, so that the heating system is environment-friendly and energy-saving, lowers the heating expenses and benefits the nation and the people, the heat energy is comprehensively used, and the heating system is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solar energy and molten salt energy storage for heating and heating, in particular to a heating system for solar energy molten salt heat storage. Background technique [0002] Most of the winter heating in the northern region still uses coal-fired boilers for heating; the CO emitted by combustion 2 Gas seriously pollutes the environment, using incineration of garbage and heating with natural gas; it also pollutes the environment, using electric heating boilers, low thermal efficiency, high cost of use and many other shortcomings, molten salt heat storage energy storage; is an emerging energy storage technology, currently molten salt Energy storage is commonly used; high-temperature salt tanks, low-temperature salt tanks, heat exchangers, electric heaters, circulating pumps, circulating high-temperature molten salt liquid, for heating and heat exchange; equipment costs are extr...
