Summary of the invention
The present invention is directed to the problem of above-mentioned prior art existence and a kind of high-performance solid electricity heat storage boiler is provided, improve the utilization rate of electric energy.
Technical scheme of the present invention is as follows:
A high-performance solid electricity heat storage boiler, is characterized in that: it is to consist 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 outward at access opening, the two ends face of each evenly distributed access opening, be respectively hole, one number service road and No. two access openings, 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; Between inner thermal insulating layer and external thermal insulation, ground, be provided with Cryogenic air circulation canal; Circulating fan has consisted of the power of thermal energy exchange centrifugal blower or axial flow blower; External thermal insulation is by heating resisting metal sheet material, to be assembled or built by laying bricks or stones the inside structure layer that forms and outboard structure layer and thermal insulation fire-resistant packing material by heat insulating refractory material to form; High temperature air circulation canal is with the assembling of heating resisting metal sheet material or by heat insulating refractory material, is built by laying bricks or stones the solid being connected with inner thermal insulating layer forming.
Described heat storage is to sinter that structural member is built by laying bricks or stones into or with its castable curing molding with silicates material.
Described inner thermal insulating layer is to make 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 blocking-up heat storage heat energy in the excessive object of inner thermal insulating layer wrapping portion.
Described circulating fan, drive Cryogenic air to send into hole, heat release one number service road through Cryogenic air circulation canal, from flowing out, No. two access openings of heat storage heat release heat up, 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 is to reduce inner thermal insulating layer hull-skin temperature with low temperature flow air, reaches the thermograde reducing between external thermal insulation inside structure layer and external thermal insulation outboard structure layer, reduces the heat radiation loss of external thermal insulation.
Beneficial effect of the present invention is:
High-performance solid electricity heat storage boiler of the present invention is owing to having designed two heat-insulation layers and having introduced the low-temperature circulating air below 150 degrees Celsius between two heat-insulation layers, inner thermal insulating layer outer surface is constantly brought the circulatory system into heat under low-temperature circulating air effect, make inner thermal insulating layer bear main heat insulation function, reduced because improving the regenerator temperature of heat storage, the standby loss of external thermal insulation.This invention, for solid electricity heat storage boiler regenerator temperature, break through 800 degrees Celsius and created condition, the heat storage capacity of heat storage is enhanced about more than once, alleviated the input weight of heat-storing material, reduced the manufacturing cost of electric heat storage boiler, saved equipment occupation space, improved equipment thermal conversion efficiency and reduced electric cost.
