Hinder the resistance wire channel B of silk.
In the present embodiment, its internal heat storage of solid heat storage electric boiler by a large amount of three kinds of different structure sizes storage
Hot brick body is piled up.Accumulation of heat brick body ingredient is mainly magnesia, and the gitter brick of three kinds of different structures has in size, structure
Institute's difference, but general structure is similar.A left side for accumulation of heat brick body, it is right, it is preceding, after be respectively a vertical flat surface, bottom surface is with logical
Saturating groove, projecting slot of the top surface with penetrating groove and for fixing heater strip.When in use, different accumulation of heat brick bodies
Mutual left and right end face fits or front/rear end fits.The bottom face paste for being buckled to its bottom surface and upper square brick of lower square brick
It closes, and groove port face, the air duct formed in several pass-through device body length directions is surrounded by these grooves.And in equipment
The groove of resistance wire is placed in the width direction of ontology, is combined with each other the channel for being formed and placing resistance wire, and resistance wire is fixed
Resistance wire, which is placed, in groove causes short circuit because being heated and deforming upon collision.Ventilating duct A and resistance wire channel B is horizontal row
Cloth is mutually perpendicular to and not in same plane, non-interference.It is and big in mechanical strength with the heat storage of this Structural assignments
It is big to be better than using the heat storage constructed by single gitter brick.
One separation layer 44 in solid heat storage device 4 is set, entire solid heat storage device 4 is divide into upper part and lower part.
Air initially enters lower floor's heat storage and is heated, later into diversion division 45, by the guide functions hot-air of diversion division 45
Continue to heat into upper strata heat storage.Hot-air changes after a circle is recycled in entire solid heat storage device 4 by the completion of heat exchanger 5
Heat.
The heating system of entire solid heat storage device 4 is divided into five units and is finely controlled from top to bottom, bulk temperature
Using closed-loop control, heater strip powers off after in paddy electricity accumulation of heat period, which group temperature reaches rated temperature, when temperature is less than setting
At a temperature of in limited time resistance wire continuing to heat.Along in heat storage body length direction, the channel of resistance wire is installed by upper
It is divided into five groups under, every group includes three heater strips, using wye connection.For every group of heater strip be all with a thermocouple into
Row individually finely controls.Extraction is monitored to data such as the working condition of every group of heater strip, real time temperatures, in the accumulation of heat period,
Which group heater strip reaches the rated temperature of setting, which group heater strip, which powers off, is stopped.So as to reach heat storage each section
The purpose of temperature equalization, the damage caused by when local temperature is excessively high that greatly reduces resistance wire.
The positive effect of the present invention is：
Building for heat storage is carried out using the accumulation of heat brick body of three kinds of different structures, is made in the stability of structure with traditional
The stability built with the gitter brick of single structure compared to mechanical structure greatly increases；
The heat storage that three kinds of gitter bricks are built, it is non-interference between resistance wire placement channel and air duct, it is effectively reduced
Contact of the resistance wire with air reduces its oxidation and greatly prolongs the resistance wire service life；On the other hand, because during air circulation not
Resistance wire can be passed through, ventilation resistance is reduced, cost has been saved when selecting wind turbine；
