Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making under creative work prerequisite
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of high-efficiency solar heat accumulation power generation system, comprise solar array 1, heat exchanger 2, tracking means 18, controller 17, heat storage can 5, steam turbine 9, generator 10, vapour condenser 12 and cooling tower 11, described heat exchanger 2 is connected with solar array 1, described tracking means 18 is arranged on roof and opens wide place, described solar array 1 is arranged on described tracking means 18, tracking means 18 and described controller 17 are electrically connected, and controller 17 can control the direction of tracking means 18 conversion solar array 1; Described heat exchanger 2 is connected with heat storage can 5 by No. I three-way pipe 3, heat storage can 5 is connected with steam turbine 9 by No. II three-way pipe 8, steam turbine 9 is connected with vapour condenser 12 with generator 10 respectively, and vapour condenser 12 is connected with feed water pump 14 with cooling tower 11 respectively, and feed water pump 14 is connected with cyclic water tank 16; Be provided with heat storage can inlet adjusting valve 4 between described No. I three-way pipe 3 and heat storage can 5, be provided with between heat storage can 5 and No. II three-way pipe 8 between heat storage can discharge control valve 7, No. I three-way pipe 3 and No. II three-way pipe 8 and be also provided with Steam Turbine's Main Vaper Valve 6.Temperature transducer is provided with in described tracking means 18.No. III three-way pipe 15 is also provided with between described No. I three-way pipe 3 and Steam Turbine's Main Vaper Valve 6.Described cyclic water tank 16 is connected with No. III three-way pipe 15 by being provided with circulating water control valve 13.
