Description
Technical field
The present invention relates to a kind of Efficient solid electric thermal storage boiler, the scattering losses of solid electricity heat storage boiler can be reduced, improve the heat utilization rate of electric heat storage boiler.
Background technology
China's haze weather is very serious, installs solid electricity heat storage boiler trough-electricity and abandons wind-powered electricity generation and carry out the effective way that accumulation of heat replacement coal-burning boiler is clean atmosphere minimizing haze weather.In recent years, this respect work makes some progress, but need the electric heat storage boiler that the high power high-temperature of regenerator temperature more than 800 degrees Celsius exports in actual applications, by the solid electricity heat storage boiler design of existing single heat-insulation layer, insulation of equipment heat leakage can be made to increase, thermal conversion efficiency reduces, electric accumulation of heat high expensive.The Efficient solid electric thermal storage boiler designing a kind of novel pair of heat-insulation layer solves in-problem key.
Summary of the invention
The present invention is directed to above-mentioned prior art Problems existing and a kind of Efficient solid electric thermal storage boiler is provided, improving the utilization rate of electric energy.
Technical scheme of the present invention is as follows:
A kind of Efficient solid electric thermal storage boiler, is characterized in that: it is made up of heat storage, inner thermal insulating layer, circulating fan, Cryogenic air circulation canal, high temperature air circulation canal, heat exchanger, external thermal insulation; Heat storage is provided with multilayer in corresponding biend inter normal direction, every layer has some groups of evenly distributed access openings, electric heater is assembled in access opening, the terminals of electric heater stretch out access opening and connect into current supply circuit outside access openings, the two ends face of evenly distributed each access opening, be hole, one number service road and No. two access openings respectively, what be connected with high temperature air circulation canal is No. two access openings, and what be connected with Cryogenic air circulation canal is hole, one number service road; Inner thermal insulating layer is located on the outer surface of heat storage except access opening; Cryogenic air circulation canal is provided with between inner thermal insulating layer and external thermal insulation, ground; Circulating fan has formed the power of thermal energy exchange by centrifugal blower or axial flow blower; External thermal insulation is that the inside structure layer and outboard structure layer that are assembled by heating resisting metal sheet material or built by laying bricks or stones by heat insulating refractory material and thermal insulation fire-resistant packing material are formed; High temperature air circulation canal is the solid be connected with inner thermal insulating layer assembling with heating resisting metal sheet material or built by laying bricks or stones by heat insulating refractory material.
Described heat storage sinters structural member into silicates material to build by laying bricks or stones or with its castable curing molding.
Described inner thermal insulating layer makes heat-insulating bridge-cut-off Standard with metallic plate, or use fire resistant heat preserving brick masonry, or build by insulation pouring material template, or be wound around parcel with fire resistant heat preserving coiled material, or use thermal insulation coatings application, or make by modes such as refractory fibre injections, reach and block heat storage heat energy in the excessive object of inner thermal insulating layer wrapping portion.
Described circulating fan, Cryogenic air is driven to send into hole, heat release one number service road through Cryogenic air circulation canal, heat up after heat storage heat release No. two access openings flow out, output to high temperature air circulation canal and be back to Cryogenic air circulation canal through heat exchanger acting cooling, form closed loop heat energy output system.
Described Cryogenic air circulation canal, be located between inner thermal insulating layer and external thermal insulation, object reduces inner thermal insulating layer hull-skin temperature with low temperature flow air, reaches the thermograde reduced between external thermal insulation inside structure layer and external thermal insulation outboard structure layer, reduce the scattering losses of external thermal insulation.
Beneficial effect of the present invention is:
Efficient solid electric thermal storage boiler of the present invention is owing to devising two heat-insulation layer and introduce the low-temperature circulating air of less than 150 degrees Celsius between two heat-insulation layers, inner thermal insulating layer outer surface constantly brings the circulatory system into heat under low-temperature circulating air effect, inner thermal insulating layer is made to assume responsibility for main heat insulation function, decrease the regenerator temperature because improving heat storage, the standby loss of external thermal insulation.This invention, break through 800 degrees Celsius for solid electricity heat storage boiler regenerator temperature and create condition, the heat storage capacity of heat storage is enhanced about more than once, alleviate the input weight of heat-storing material, reduce the manufacturing cost of electric heat storage boiler, save equipment occupation space, the equipment thermal conversion efficiency of improve reduces electric cost.
