Problems solved by technology

Secondary batteries cannot continue to supply external power for a long time when the power supply is interrupted due to the need for commercial power or other power generation devices to charge them.
However, diesel generators have disadvantages such as poor cleanliness and environmental protection, large noise and vibration, and single fuel.

[0046] heat storage process

[0047] The solar heat is collected by means of curved surface light collection, and a heat source with a temperature of 250°C is supplied to the absorption solution in the steam cycle shell during the heat storage process. The working fluid of the absorption solution is water, the absorbent is LiBr, and the mass percentage concentration of the absorption solution is 60wt% at the beginning of heat storage. The heat storage shell is in communication with the steam circulation shell. Heat storage agent is NaNO 3 、KNO 3 and NaNO 2 a mixture of the heat storage agent NaNO 3 、KNO 3 and NaNO 2 The mass percent concentration of the heat storage agent is 7wt%, 53wt% and 40wt%, and the freezing point of the heat storage agent is 142°C. When the heat storage is terminated, the concentration of the absorption solution rises to 70wt%, and 90% of the heat storage agent melts into a liquid state, and its temperature is 142°C.

Abstract

The invention relates to a standby power system and a power supply method thereof. The standby power system comprises energy storage equipment, a steam cycle installation, a steam turbine and a generator, wherein the energy storage equipment comprises an energy storage shell and at least one heat accumulator arranged in the energy storage shell; the steam cycle installation comprises a steam cycleshell which is filled with absorbent solution and connected to the exhaust steam end of the steam turbine, and a steam generator which is arranged in the steam cycle shell and connected to the upstream end of the steam turbine; and the energy storage shell is connected to the steam cycle shell by a pipeline. The standby power system can convert heat stored by the heat accumulator into electric power and can accumulate heat to the heat accumulator by other heat sources. The power system has good cycle performance, wide application and simple and reliable using method, is safe, clean and environment-friendly, and is suitable for use.

Description

technical field [0001] The invention relates to a power supply and heat supply technology in the field of thermal energy engineering, in particular to a backup power supply system that stores energy through a heat storage agent and produces high-temperature steam by absorbing heat from a solution to drive a turbogenerator to generate electricity and its power supply method. [0002] Background technique [0003] The existing power supply system generally supplies power from the grid and backup power. Usually, the backup power supply for power failure or natural disaster mainly includes secondary battery and diesel (or other fuel oil) generators. Secondary batteries cannot continue to supply external power for a long time when the power supply is interrupted because they need commercial power or other power generation devices to charge them. However, diesel generators have disadvantages such as poor cleanliness and environmental protection, high noise and vibration, and sin...
