Referring to fig. 1, the working principle of the present invention is specifically as follows:
firstly, a heat storage working condition:
when the heat storage is started, the heat storage switch 81 is first closed to connect the power grid 8 and the high-temperature electric heat storage module 1, and the electric heating pipe 12 starts heating to heat the high-temperature electric heat storage module 1.
When the temperature of the first temperature sensor 91 arranged in the high-temperature electric heat storage module 1 reaches a preset threshold (for example, 650 ℃), the power grid 8 automatically turns off the heat storage switch 81, and the heat storage process is finished.
Secondly, heating working conditions:
the heat generated by the electric heating tube 12 in the high-temperature electric heat storage module 1 heats the shell-and-tube heat exchanger 2 through the heat exchange coil 11 and the shell pass of the shell-and-tube heat exchanger 2.
During heat supply, water flows from an outlet at the upper end of the tube side of the shell-and-tube heat exchanger 2, passes through the first three-way valve 71 and the third three-way valve 73 and then enters an inlet of the load terminal 5 to form a water supply passage. The water flow starts from the outlet of the load terminal 5, passes through the third pump 68, the fourth electric control valve 64, the fourth three-way valve 74, the second three-way valve 72, the second pump 67 and the third electric control valve 63, and then enters the tube side lower end inlet of the shell-and-tube heat exchanger 2. And the heat supply to the load terminal 5 is realized through the water flow circulation of the tube side of the shell-and-tube heat exchanger 2.
During heat supply, the heat release power of the high-temperature electric heat storage module 1 is mainly adjusted by the first electric adjusting valve 61. The temperature of the return water is monitored by the fourth temperature sensor 94, and the opening degree of the first electric regulating valve 61 is regulated, so that the heat release power of the high-temperature electric heat storage module 1 can be regulated.
Thirdly, cooling working condition:
(1) cooling by means of lithium bromide units 3
In the lithium bromide unit 3, a heat source circulation path starts from an outlet at the upper end of a tube pass of the shell-and-tube heat exchanger 2, enters the lithium bromide unit 3 after passing through a first three-way valve 71, and then enters an inlet at the lower end of the tube pass of the shell-and-tube heat exchanger 2 after passing through a second three-way valve 72, a second pump body 67 and a third electric regulating valve 63 to form circulation.
The cold source circulation path starts from the cold source outlet of the lithium bromide unit 3, and then enters the cold source inlet of the lithium bromide unit 3 after sequentially passing through the third three-way valve 73, the load terminal 5, the third pump body 68, the fourth electric regulating valve 64 and the fourth three-way valve 74.
When the cooling power of the lithium bromide unit 3 needs to be adjusted, the temperature of the return water is monitored only through the fourth temperature sensor 94, and the opening degree of the first electric adjusting valve 61 is adjusted, so that the heat release power of the high-temperature electric heat storage module 1 can be adjusted, and the cooling power of the lithium bromide unit 3 can be adjusted by adjusting the heat release power of the high-temperature electric heat storage module 1 from the heat source circulation path.
Particularly, when the power grid 8 receives a peak regulation instruction and needs to cut off part of the electric load (namely the load terminal 5), the heat storage switch 81 is firstly switched off, then the heat release power of the high-temperature electric heat storage module 1 is adjusted by the method, the cooling power of the lithium bromide unit 3 is increased, and the process balance is finally realized.
(2) Cooling by means of an electric refrigerating unit 4
The cold source circulation path of the electric refrigerator set 4 starts from the outlet of the electric refrigerator set 4, passes through the first pump 66, the second electric control valve 62 and the load terminal 5, and finally returns to the outlet of the electric refrigerator set 4.
When the cooling power of the electric refrigerating unit 4 needs to be adjusted, the cooling power required by the electric refrigerating unit 4 is obtained according to the real-time cooling demand of the load terminal 5 and the real-time refrigerating power of the lithium bromide unit 3, and then the electric refrigerating unit 4 is adjusted to realize the balance of the cooling and the demand.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
