Device for transferring heat in solid energy storage body by means of high-temperature steam

Abstract

The invention discloses a device for transferring heat in a solid energy storage body by means of high-temperature steam, water in a pure water tank is poured into the interior of a heating pipe in a high-temperature steam generator, heat exchange is conducted in a high-temperature state, the liquid water is changed into the high-temperature steam through the heat exchange, the high-temperature steam enters a high-temperature chamber and then enters a saturated steam generator, and the high-temperature steam and the liquid water in the saturated steam generator are fully mixed, and the liquid water is heated to a needed temperature. When the temperature is higher than 100 DEG C, saturated steam with different pressure is generated. According to the device for transferring the heat in the solid energy storage body by means of the high-temperature steam, the characteristics of large latency for vapouring water and good steam flowability are fully utilized, even though vaporization is conducted on the water inside a heat storage body, internal heat of the heat storage body is changed into the latent heat of the steam, the steam is led out, and hot water is added. Accordingly, the problem that the heat transfer speed is slow is solved, the heat storage temperature of the heat storage body can be greatly improved to about 1000 DEG C, and the unit volume heat storage capacity is increased.

Description

technical field [0001] The invention relates to the field of electric energy control, in particular to a device for transferring heat in a solid energy storage body by using high-temperature steam. Background technique [0002] Power is divided into peak power, flat power and valley power according to the time of use. In order to balance the grid, shift peaks to fill valleys, and encourage the use of valley electricity, the price of valley electricity is much lower than normal electricity prices. At present, the technology of using solid heat storage to store and use off-peak electricity is very mature. The process of this technology is to heat the solid heat storage material such as refractory bricks with the heat released by the heating wire, and the heating temperature reaches 400-500°C, and store the heat in the solid heat storage material. When using heat, a fan is used to send air into the channel between the solid heat storage materials. After the air is heated, it ...
