Description
Technical Field
The present invention relates to a method for filling a thermal storage material for increasing the thermal storage density of sensible heat of a solid, and also relates to a thermal storage apparatus using the method for filling a thermal storage material.
Background
Sensible heat storage is heat absorbed or released when the temperature of a substance rises or falls, and the property of the substance does not change. The sensible heat storage material is divided into a liquid type and a solid type, and the common high-temperature solid sensible heat storage material is gravel, sand, bricks, ceramics, glass, iron, aluminum, concrete, ore, magnesia bricks and the like.
For high temperature solid sensible heat substances, the heat carrying medium or the medium for absorbing thermal energy or heat from an external source is a fluid substance. The heat transfer fluid may be water, air, any hydrocarbon fluid (e.g., hot oil), molten salts (e.g., sodium nitrate, potassium nitrate, magnesium chloride, etc.), or mixtures of these salts. The heat carrier materials, hydrocarbon fluids, molten salts, must be characterized by a low melting point so that they do not solidify during flow in the circuit. At present, the main heat exchange form of the high-temperature solid heat storage material is convection of heat carrying fluid air.
The Chinese patent application (application number: 201811189662.2) discloses a solid electric heat storage device, which comprises a sealed shell, a heat storage body, a heat storage air channel, a heating plate, an air inlet distribution plate and an air outlet distribution plate; four heat storage air channels are uniformly arranged in the heat storage body along the flowing direction of the heat storage air. The heat storage device has the following defects: the heat storage air channel is arranged in the heat storage body in order to realize heat exchange of the heat storage body, so that the channel needs to be specially designed on the heat storage body, the complexity of the forming process of the heat storage body is increased, and meanwhile, the production cost is also increased. The heat accumulator can adopt a magnesium iron brick, and the heat accumulator comprises the following components in percentage by weight: 60.5 percent of MgO, 20.5 percent of Fe2O3, 9.5 percent of FeO and 5 percent of SiO2, and the balance of water. In the preparation process, the components are firstly crushed into granules, which improves the difficulty of the preparation process of the magnesium-iron brick, and the production cost is higher, and then, the various crushed and granulated components are bonded together, and a channel is also required to be reserved to realize air heat exchange, however, the bonding is to remove the gap, and the air duct is additionally provided with the gap, so that the improvement of the sensible heat storage density of the solid is not facilitated, and the heat storage efficiency cannot be improved.
Disclosure of Invention
The first purpose of the invention is to provide a heat storage material filling method which is low in cost and small in process difficulty and can improve the solid sensible heat storage density.
The first object of the invention is achieved by the following technical measures: a heat storage material filling method for improving solid sensible heat storage density is characterized by comprising the following steps:
s1, laying a layer of small-particle solid heat storage material at the bottom of the shell, laying a layer of medium-particle solid heat storage material on the small-particle solid heat storage material, and laying a layer of large-particle solid heat storage material on the medium-particle solid heat storage material;
