Specific embodiment
With reference to embodiment, the present invention is furture elucidated, it should be understood that following specific embodiments are only used for
It is bright the present invention rather than limit the scope of the invention.
Fig. 1 is the structural diagram of the present invention, as shown in Figure 1, the separate type fuse salt thermal storage electric boiler of the present invention, including
Boiler tank body 1 and heat exchanger 10, the boiler tank body connect the heat exchanger, the separation by separate heat pipe 2
Formula heat pipe includes the heat pipe evaporator section 2-1 being arranged in the boiler tank body and the heat pipe cold being arranged in the heat exchanger
Solidifying section 2-2, is connected, the boiler between the heat pipe evaporator section and the heat pipe condenser section by heat pipe connecting pipe
Heat storage medium 5 and electrical immersion heater 3 are provided with inside tank body, the boiler tank body has distinguished 6 He of heat storage medium entrance
Heat storage medium outlet 7, heat exchanger the inside are provided with heat transfer medium 11, and the heat exchanger connects heat transfer medium and enters respectively
Mouth 12 and heat transfer medium outlet 13.Electrical immersion heater utilizes heat storage medium in wind-powered electricity generation, photoelectricity or paddy electricity heating boiler tank body 1
5, it converts electrical energy into high temperature heat and is stored in boiler tank body, it is by separate heat pipe 2 that heat is quick in peak of power consumption
Heat exchanger 10 is passed to, 11 water at low temperature of heat transfer medium absorbs heat and becomes high-temperature steam or high-temperature water for heating, is situated between by conducting heat
Matter takes away heat, and boiler tank body temperature reduces, and opening electric heater carries out heat cycles.
There are heat pipe evaporator section 2-1, electrical immersion heater 3 inside the boiler tank body 1, inside fills heat storage medium 5,
Tank body top setting heat storage medium entrance 6, tank body lower part setting heat storage medium export 7, and entire boiler tank body sets insulating layer 4.
The separate heat pipe 2 has good heat transfer property, can the heat stored quickly be passed to heat exchanger
Inside 10, the thermal energy of high efficiency extraction storage；Separate heat pipe 2 divides for two parts：Heat pipe evaporator section 2-1 is arranged on boiler tank body 1
Inside, heat pipe condenser section 2-2 are arranged on inside heat exchanger 10 so that high-temperature molten salt and water at low temperature are completely isolated, avoid mutually
Explosion danger occurs for leakage；Heat pipe evaporator section 2-1 and condensation segment 2-2 can be installed more at a distance, can be reduced compared with remote conveying
The thermal loss sent.Stored using sensible heat/heat release when, heat pipe operating temperature is selected higher than fused salt solidification point, when pot in-furnace temperature is low
When fused salt condensation temperature, heat pipe is stopped, and maintains pot in-furnace temperature higher than fused salt solidification point, fused salt be constantly in liquid into
Row sensible heat storage/heat release cycle.Stored using latent heat/heat release when, heat pipe operating temperature is selected less than fused salt solidification point, when warm in boiler
When degree is less than fused salt solidification point, heat pipe, which works on, transmits heat, and fused salt starts to solidify, and latent heat storage/exothermic process is that fused salt exists
The process of solid-liquid phase change nearby occurs for fusing point, and in entire storage/heat release cyclic process, fused salt is affixed to liquid, liquid to solid phase state
Cycle.
The heat storage medium 5 is fused salt, with temperature in use is wide, specific heat capacity is big, steam forces down, chemical stability is good
Feature, and it is cheap, it is good heat storage medium, sensible heat storage/heat release can be carried out, latent heat storage/heat release can also be carried out.
/ heat release is stored using sensible heat, fused salt is heated into liquid, and the temperature of boiler tank body is maintained to be higher than the solidification point of fused salt, profit always
With the thermal switch characteristic of heat pipe, heat pipe operating temperature is selected to be higher than the solidification point of fused salt, when boiler tank body temperature is less than heat pipe
During operating temperature, heat pipe is stopped, and heat can not pass to heat exchanger by heat pipe at this time, so as to which a pot in-furnace temperature be maintained to be higher than
Fused salt solidification point makes fused salt that liquid be maintained to carry out sensible heat accumulation of heat always, and fused salt can effectively be avoided to inhale heat release due to long-time
It is separated./ heat release is stored using latent heat, using fused salt latent heat of phase change, makes fused salt that solid-liquid phase-state change occur and inhale/put
Heat, selecting heat pipe operating temperature, when pot in-furnace temperature is less than fused salt solidification point, heat pipe works on, pot less than fused salt solidification point
In-furnace temperature reduces, and fused salt undergoes phase transition heat release at this time, and fused salt gradually switchs to solid-state by liquid, and storage/thermal discharge is big.
The electrical immersion heater 3 can be that spiral cast heater can also be cylindrical electric heater.Spiral
Tube electric heater is arranged on thermal bottom and accumulator tank is coaxially arranged；Multiple cylinder electric heaters are evenly distributed on
Thermal bottom is evenly heated heat storage medium.
Valve a8 on the heat storage medium entrance 6 is set, valve b9 is set in heat storage medium outlet 7.
