Safe and efficient solid heat storage electric boiler with variable heat transfer surface

Abstract

The invention discloses a safe and efficient solid heat storage electric boiler with a variable heat transfer surface, and relates to the technical field of heat supply equipment. A heating device for heating the electric boiler is arranged; and a movable fixed heat accumulator frame is movably installed at the bottom of the electric boiler and used for fixing a heat accumulator and achieving stable movement of the heat accumulator. The heat accumulator is mounted on the movable fixed heat accumulator frame and is used for storing heat; a circulating water pipeline is in contact with the heat accumulator and is used for conducting heat of the heat accumulator; and a heat insulation material is used for wrapping the movable fixed heat accumulator frame and is used for heat insulation and supporting. According to the safe and efficient solid heat storage electric boiler, the purpose of adjustable load operation in the operation process of the electric boiler is achieved by changing the heat transfer area between the heat accumulator and the circulating water, the purpose of energy-saving operation is achieved, variable load heat exchange of the heat exchange face of the circulating water and the heat accumulator is achieved, and the problem of circulating water vaporization during operation of the electric boiler is solved through the solid heat storage electric boiler.

Description

technical field [0001] The disclosure of the invention relates to the technical field of heat supply equipment, in particular to a safe and efficient solid heat storage electric boiler with variable heat transfer surface. Background technique [0002] The solid heat storage electric boiler equipment uses the cheap electricity during the low valley period to convert the electric energy into high temperature heat energy and store it in the heat storage body, and releases the stored heat during the peak period of electricity consumption and makes reasonable use of it, which has the advantages of peak shaving and valley filling, saving and emission reduction . Therefore, in the field of heating, solid heat storage electric boilers have a wide range of applications. [0003] Although solid heat storage electric boilers can fully utilize the benefits of off-peak electricity, there are certain defects in energy utilization. The traditional solid heat storage electric boiler adopt...
