Overlap-type solid heat accumulation device

Abstract

The invention relates to an overlap-type solid heat accumulation device which comprises at least three groups of heat accumulation components for storing heat energy and an accommodating shell for accommodating the heat accumulation components, the three groups of heat accumulation components are sequentially and adjacently arranged in the accommodating shell from top to bottom; each of the heat accumulation components comprises a heat accumulation body for storing heat energy and a heating wire for releasing heat energy; the heat accumulation bodies are first magnesite bricks and at least twofirst magnesite bricks are adjacently arranged; the surfaces of the first magnesite bricks are of loose porous structures; a through hole is correspondingly formed between every two adjacent first magnesite bricks; the heating wires penetrate through the inner sides of the through holes; a heat exchanger is arranged at the bottom end of the interior of the accommodating shell; and a water inlet pipe and a water outlet pipe are adjacently arranged on one side of the heat exchanger in a communicating manner. In short, according to the technical scheme, compared with the traditional solid heat accumulation device, the overlap-type solid heat accumulation device effectively solves the technical problems that the heat accumulation performance is poor, the energy consumption is high and the heat accumulation device is likely to be damaged through a coherent and compact structure.

Description

Technical field [0001] The invention relates to the technical field of heat storage devices, in particular to a superimposed solid heat storage device. Background technique [0002] The solid heat storage device is a product of the conversion of coal to electricity. It is a heat carrier equipment that replaces coal-fired boilers with clean energy and has made great contributions to the country's air purification and pollution reduction. [0003] However, with the continuous use of solid heat storage devices in the society, some unavoidable drawbacks have gradually appeared. On the one hand, traditional solid heat storage devices have poor heat storage performance and high energy consumption. The heat storage device is very prone to damage to the heat storage device. Furthermore, if the heat storage device is damaged, if it is not found in time and effectively treated, it will directly cause a chain reaction, and adjacent devices will also be affected and damaged. When this kind of...
