Efficient heat exchange system suitable for solid heat storage device

Abstract

The invention discloses an efficient heat exchange system suitable for a solid heat storage device. The efficient heat exchange system comprises a heat storage chamber, a high-temperature water tank and a low-temperature water tank, wherein the heat storage chamber, the high-temperature water tank and the low-temperature water tank are arranged independently, semiconductor heat accumulators are arranged in the heat storage chamber; the heat storage chamber communicates with the low-temperature water tank through a water supply pipeline; the heat storage chamber further communicates with the high-temperature water tank through a steam pipeline and a hot water pipeline; one end port of the steam pipeline is arranged at the top of one side of the heat storage chamber, and the other end communicates with a water surface of the high-temperature water tank; a check valve is further arranged on the steam pipeline; one end of the hot water pipeline is arranged at the lower part of the heat storage room, and the other end of the hot water pipeline is connected with the upper part of the high-temperature water tank; and a pipeline pump is arranged on the hot water pipeline. According to theefficient heat exchange system, the design is more reasonable, due to the heat exchange performance of the liquid is greatly higher than that of gas, the low-temperature operation temperature of the heat accumulators in the heat release stage is reduced, the heat exchange efficiency of the solid heat storage device is improved, the heat exchange area is reduced, the size of the solid heat storagedevice is reduced, and the electricity consumption of the heat exchange system is reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange systems for solid heat storage devices, in particular to a high-efficiency heat exchange system suitable for solid heat storage devices. Background technique [0002] The expansion of the city scale and the change of the power consumption structure make the power load difference between the day and night of the power grid larger and larger, resulting in an increasing difference between the peak and the valley of the power grid, which brings difficulties to the safe and efficient operation of the generator set. The valley power heat storage device is used. The heat storage body can be heated to a certain temperature by using the electricity during the low valley period. While meeting the needs of the low valley period, the residual temperature of the heat storage body can meet the needs of the flat power period and the peak power period, and play the role of shifting the peak and filling the v...
