Problems solved by technology

Most of the existing switchable heat storage devices adopt a detachable structure. The dust in the heat storage body can be cleaned by disassembling the heat storage device. Since the dust in the heat storage device needs to be cleaned regularly, the heat storage device needs to be interrupted every time. The heat storage body is removed for production to clean the dust. This method of manually cleaning the dust greatly reduces the production efficiency

Abstract

The invention provides an ash self-cleaning type heat storage device capable of automatically cleaning ashes, which relates to a heat storage device. The ash self-cleaning type heat storage device comprises a shell and a heat storage body, wherein the heat storage body is placed in the shell; a low temperature flue gas passage and a low temperature combustion-supporting air passage, which are communicated with the low temperature side of the heat storage body, are arranged at the top of the shell; a high temperature flue gas passage and a high temperature combustion-supporting air passage, which are communicated with the high temperature side of the heat storage body, are arranged at the bottom of the shell; and ash unloading valves are respectively arranged on the high temperature flue gas passage and the high temperature combustion-supporting air passage. The ash self-cleaning type heat storage device provided by the invention has the advantages that simple structure and low cost are achieved, ashes can be automatically cleaned and periodically discharged, the efficiency of the heat storage device is increased and the service life of the heat storage device is prolonged.

Description

technical field [0001] The invention relates to a heat storage device, in particular to a novel self-cleaning type heat storage device. Background technique [0002] High-temperature air combustion technology is an advanced combustion technology with the advantages of energy saving and emission reduction, and the heat storage device is the core of this technology. The dust remaining in the heat storage body when the flue gas passes through the heat storage body is an important factor affecting the normal, efficient and durable operation of the heat storage device. Most of the existing switchable heat storage devices adopt a detachable structure. The dust in the heat storage body can be cleaned by disassembling the heat storage device. Since the dust in the heat storage device needs to be cleaned regularly, the heat storage device needs to be interrupted every time. In production, the heat storage body is removed to clean the dust. This method of manually cleaning the dust g...
