Abstract

The invention provides a fused salt heat storage heating system. The fused salt heat storage heating system comprises a single fused salt tank. A pore plate used for separating low-temperature fused salt and high-temperature fused salt is arranged in the fused salt tank. The backflow low-temperature fused salt subjected to heat exchange is contained in the lower zone of the pore plate. By arranging the single fused salt tank and the pore plate, and through the characteristic that the density of fused salt is lowered with increase of the temperature, heat storage and heating are achieved; and compared with traditional fused salt heat storage heating systems, the investment cost is lowered, the system technological process is simplified, the equipment occupied size is reduced, and the fused salt outlet temperature is stable.

Description

technical field [0001] The invention relates to the field of molten salt energy storage, in particular to a molten salt heat storage heating system. Background technique [0002] With the rapid development of industry, our country is facing enormous environmental pressure, especially smog pollution. In order to effectively control smog pollution and improve air quality, many provinces and cities have vigorously promoted the "coal-to-electricity" project, that is, the use of electric heating to replace the heating method of traditional coal-fired boilers. At the same time, in response to the large gap between daytime and nighttime peaks and valleys of power supply in my country, the government has promulgated preferential policies for nighttime low-peak electricity consumption, encouraging the use of cheap low-valley electric heating heat storage materials to store heat energy, so as to achieve the purpose of "shaving peaks and filling valleys". [0003] Molten salt, referre...
