Energy storage canister 1 is used to the extra electric energy of the intermittent electric power device of Photospot solar equipment etc. being converted into thermal energy and deposit
Storage in heat-storage medium and by the heat being stored in heat-storage medium by Steam Reforming into high-pressure water vapor, there is chamber
Body 15 and tank skin.The high-temperature liquid states heat-storage medium such as sodium chloride is placed in cavity 15.Heating rod is provided in energy storage canister 1 (in figure
It is not shown), it is connect with intermittent electric power device, electric energy heating is supplied by intermittent electric power device.In energy storage, by heating rod
Thermal energy is converted electrical energy into, is stored in heat-storage medium；In exoergic, heat-storage medium is heated into water by heating rod and is steamed
Vapour.Tank skin is made of inner wall 11, several interlayer walls 13 and outer wall 12, is vacuum cavity 14 between every layer.Energy storage canister 1 is additionally provided with
Vacuum degree control interface 16 and energy storage exoergic interface 17.Hook 18 is arranged on the top of inner wall 11, interlayer wall 13 etc., for reducing
Tank body and external contact area, reduce thermal losses.Energy storage canister 1 is connected with control unit 6, is come by the control of control unit 6
Thermal energy is converted electrical energy into during energy storage and is stored in heat-storage medium, and leads to the heat being stored in heat-storage medium in exoergic
Steam Reforming is crossed into high-pressure water vapor.
Vacuum degree adjusts unit 2 and is used to periodically detect the vacuum degree of each vacuum cavity 14 and adjusts vacuum degree, including true
Sky pump 21, B/P EGR Back Pressure Transducer EGR 22 and vacuumizing joint 23.Each vacuum cavity 14 is equipped with B/P EGR Back Pressure Transducer EGR 22.Each vacuum is empty
Chamber 14 can evacuated connector 23 connect or disconnect with vacuum pump 21.Vacuum pump 21 is connected with control unit 6, by control unit
6 controls are turned on and off.The vacuum degree of each vacuum cavity 14 is held in not higher than 0.5mp.It is true when some vacuum cavity
When reciprocal of duty cycle exceeds 0.5mp, triggering vacuum degree adjusts task, and vacuumizing joint 23 is connected to the vacuum cavity, starts to vacuumize, treat
When vacuum degree drops to below 0.2mp, stop vacuumizing, vacuumizing joint 23 is detached from energy storage canister.
