Description

Technical Field

[0001] The utility model relates to the field of boilers, in particular to a solid electric heat storage boiler. Background Art

[0002] For example, patent announcement number CN203671902U discloses a high-efficiency solid electric heat storage boiler, which is composed of a heat storage body, an inner insulation layer, a circulating fan, a low-temperature air circulation channel, a high-temperature air circulation channel, a heat exchanger, and an outer insulation layer; the outer surface of the heat storage body and the high-temperature air circulation channel is built with refractory insulation bricks to form an inner insulation layer, so that the heat energy in the heat storage body can only flow into the heat exchanger from the high-temperature air circulation channel. The high-temperature air enters the heat exchanger under the gravity of the circulating fan and performs work. The low-temperature air formed by cooling flows back to the No. 1 channel hole through the low-temperature air circulation channel. The low-temperature air absorbs heat in the channel hole and becomes high-temperature air. It enters the high-temperature air circulation channel through the No. 2 channel hole and performs work. The above application has created conditions for the solid electric heat storage boiler to break through the 800-degree Celsius heat storage temperature, which has more than doubled the heat storage capacity of the heat storage body, improved the equipment's heat conversion efficiency, and reduced electricity costs.

[0003] The heat exchanger and its external protective shell are usually fixed directly on one side of the boiler. Therefore, after the heat exchanger has been used for a period of time, it will be blocked inside, which will affect the heat exchange efficiency of the heat exchanger and need to be disassembled, cleaned and maintained. However, the fixed heat exchanger is not convenient for disassembly, cleaning and maintenance. Utility Model Content
