Solid heat storage device

Abstract

The embodiment of the invention discloses a solid heat storage device. The solid heat storage device is characterized by comprising a shell, an inner container arranged in the shell and divided into a heat storage bin and a heat supply bin which communicate with each other, solid heat storage bodies arranged in the heat storage bin, heating pipes arranged in the solid heat storage bodies, ventilation channels arranged in the solid heat storage bodies and penetrating the solid heat storage bodies, an air flue making the heat storage bin and the heat supply bin communicate with each other, and a draught fan used for driving gas in the air flue to flow, wherein the air flue communicates with the heat storage bin through vents formed in the side wall of the heat storage bin and increased from bottom to top sequentially; and the ventilation channels are obliquely arranged, and the two ends of each ventilation channel face an upper opening and a lower opening. Therefore, through the oblique arrangement of the ventilation channels, the heat storage and supply efficiency is improved, the vents are sequentially increased from bottom to top, air force obtained at the positions away from the vents and air force obtained at the positions close to the vents are basically balanced, and the situation that the heat storage and supply efficiency is affected due to the generation of turbulent flow is avoided.

Description

technical field [0001] The invention relates to the field of solid heat storage, in particular to a solid heat storage device. Background technique [0002] With the increasing demand for energy, there is a shortage of energy in the world. In order to solve the defect of insufficient power during peak power consumption, the power sector has formulated preferential policies for power consumption, and the price of electricity is lower during low power consumption. Therefore If thermal energy storage can be carried out during low power consumption, the stored thermal energy can be used during peak power consumption, thereby alleviating the power consumption pressure during peak power consumption. [0003] The main function of solid heat storage is to heat the solid heat storage material and store heat energy. It can store heat energy when electricity consumption is low, and continuously release the stored heat energy to the heating system or domestic hot water system when heat ...
