Abstract

The invention discloses a heat storing device using asphalt. The heat storing device comprises a heat preservation shell, a heat input access and a heat exchange device, a heat output access, a heat exchange device, and an expansion protection device. The asphalt is filled in heat exchange physical spaces as a heat storing medium; and a heat storing temperature is 400 DEG C. The heat storing device provided by the invention uses natural asphalt, oil asphalt and waste asphalt road surfaces as the heat storing medium, so as to achieve the beneficial effects of stable heat storing and exchange operation properties, simple production technique, easiness of maintenance and the like. The heat storing device provided by the invention can be widely applied to various fields of heat recycle, and is suitable of gas heat storage and exchange, and liquid heat storage and exchange.

Description

technical field [0001] The present invention relates to an asphalt heat storage device and method. The heat storage device includes a thermal insulation shell, a heat input passage, a heat exchange device, a heat output passage, a heat exchange device and a protection device. The physical space for heat exchange is filled with asphalt as a heat storage medium , The heat storage temperature is 400°C. It belongs to the field of energy and environment. Background technique [0002] The maximum heat storage temperature of the current heat storage device is within 350°C, the heat storage cost is high, the operation cost is high, the performance is unstable, and there are unsafe factors, and there is no mixing of metal wires in the heat exchange heat storage medium as the heat exchange heat transfer medium precedent. [0003] According to the asphalt heat storage device realized in the present invention, the heat storage temperature can be 400°C, the asphalt is used as the heat ...
