Abstract
The utility model relates to a thermal energy storage device, in particular to a solid thermal energy storage device which utilizing electric heating to carry out energy storage of solids. The solid thermal energy storage device is provided with a solid thermal storage body in a casing, a thermal insulation layer is arranged between the thermal storage body and the casing, a thermal conductive element and a heating element are arranged in the thermal storage body. The solid thermal energy storage device has the advantages that the energy storage device can adjust the volume size according to the capacity of energy storage or overlap a plurality of energy storage devices; the single energy storage device has good volume maintenance, the number of groups of stored thermal energy can be arbitrarily adjusted, the solid energy storage body can improve the heating temperature to change more electric energy to the thermal energy to be stored, if using water for energy storage, the water can be vaporized due to the temperature increase, thereby not only losing the thermal energy along with the vaporization, but also generating gas pressure by serious vaporization due to the temperature increase and further causing the energy storage body to be dangerous.
Description
Technical field
The utility model relates to a kind of hot energy storage device, relates in particular to a kind of hot energy storage device of solid type that solid is carried out accumulation of energy with electrical heating.
Background technology
Current social energy shortage makes resources-type product appreciate at a gallop, and the heating heat energy that enterprise provided is realized with coal, but coal price rises steadily, and has brought huge pressure for heating enterprise, at last the pressure that goes up is turned to the user.And the problem of supply of electric power also is very outstanding, type of production and resident living electricity consumption make uses the electric forming peak daytime, and usually power cuts to limit consumption by day, but midnight, power consumption sharply descended, daytime and electricity consumption in evening form a sharp contrast, and therefore country encourages the electricity consumption in evening.Therefore electrically heated heating system occurs using, carried out accumulation of energy with the low ebb electricity at night.But present energy storage boiler is the carrier of water as accumulation of energy, but the limitation of water is big, and water can only be heated to below 90 ℃, and the requirement of the resistive heater in water is high, must prevent electric leakage, also needs insulation, energy storage capacity is little like this, and volume is big, has limited large tracts of land and has promoted the use of.
The utility model content
Provide a kind of solid type hot energy storage device for solving the problems of the technologies described above the utility model, purpose is to improve energy storage capacity, reduces cost, and utilizes the low ebb electricity to carry out energy storage, alleviates user's burden.
For reaching the hot energy storage device of above-mentioned purpose the utility model solid type, in housing, be provided with the solid thermal store, be provided with heat-insulation layer between thermal store and the housing, in thermal store, be provided with heat conducting element and heating element heater.
Described heat conducting element is parallel in thermal store or head and the tail connect setting.
The import of described heat conducting element and outlet are arranged on an end of thermal store or are separately positioned on the two ends of thermal store.
In the described heat conducting element is liquid or gas; Liquid is water, and gas is air.
Described housing is a metal shell.
Described thermal store is concrete, cobblestone, common brick or stone material.
Described heating element heater is a resistance wire.
Described resistance wire is parallel or head and the tail connect setting.
Described resistance wire two ends are located at an end of thermal store or are separately positioned on the two ends of thermal store, resistance wire two termination power supplys.
Described heat-insulation layer is a rock wool.
Described housing end face is provided with the lifting screw hole.
The utility model has the advantages of: energy storage device of the present utility model can be adjusted the size of volume according to the size of energy storage, maybe can be with a plurality of energy storage device stacks; The volume of single energy storage device, maintainability is good, can arbitrarily adjust the group number of amount of stored heat, the energy storage body of solid can improve heating-up temperature, more electric energy is become heat energy to be stored, if water energy storage meeting Yin Wendu rising water is vaporized, not only lose heat energy and also can Yin Wendu rising serious vaporization in the energy storage body produce air pressure with vaporization, the energy storage body is caused danger.
