Solid heat storage electric boiler with high unit heat storage capacity and long service life

Abstract

The invention provides a solid heat storage electric boiler with high unit heat storage capacity and a long service life, and belongs to the technical field of solid electric heat storage. The solid heat storage electric boiler comprises a heat storage body, heating channels, air feeding channels, air exhausting channels, heating wires, a heat insulation base, an intelligent measuring and controldevice, a gas deactivation treatment device, a purifying filtering device, a bypass control device and the like. The multiple heating channels, the multiple air feeding channels and the multiple air exhausting channels form a space stereoscopic lattice communication structure or a space parallel-connection structure, the temperature difference of the interior of the heat storage body is remarkablydecreased, especially, the temperature of the heating wires, the temperature of the heating channels and the temperature of the heat insulation base are lowered, and accordingly, boiler collapse andother serious heat fault problems are effectively avoided; multiple designs are adopted and organically combined, superheat and oxidation of the heating wires are reduced, and oxidation breaking or superheat deforming of the heating wires is avoided; and accordingly, the unit heat storage capacity of the solid heat storage electric boiler is effectively improved, and the service life of the solidheat storage electric boiler is effectively prolonged; and the solid heat storage electric boiler has the advantages of being simple in structure, low in cost, reliable in operation, convenient to maintain and the like.

Description

technical field [0001] The invention relates to a solid heat storage electric boiler, in particular to a solid heat storage electric boiler with high unit heat storage capacity and long service life. The utility model belongs to the technical field of solid electric heat storage. Background technique [0002] In the current solid heat storage device, furnace collapse, broken wire or deformation of the heating wire are common faults and problems, which have a serious impact on the stable and reliable operation of the solid heat storage device, and will cause huge economic losses. The main reason for the collapse of the furnace is the serious uneven temperature distribution inside the heat storage body. At the same time, in order to avoid this problem, the method of lowering the heat storage temperature is often used in actual operation, which will cause a large drop in heat storage capacity. Lead to insufficient system output or a substantial increase in investment. The mai...
