Embodiment Construction

[0026] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the power generation system of the double heat exchange temperature control device of the present invention includes a heat collector 1, a boiler 2, a power generation device 3, a gas condenser 4, a cooling device 5, a soft water tank 6 and a plurality of hydraulic pumps.

[0028] The solar collector 1 is heated by the solar device and transmits the high-temperature medium to the boiler 2. The steam generator in the boiler 2 generates steam to drive the power generation device 3 to generate electricity. The low-temperature medium after power generation passes through the condensing device 4, cooling device 5, soft water The tank 6 and hydraulic pumps go back into the boiler 2 . In an embodiment ...

Abstract

The invention relates to a double heat exchange temperature control device. The device receives an outside heated high temperature medium, and comprises a primary heat exchange device and a secondary heat exchange device, wherein the primary heat exchange device comprises a primary heat exchanger, a middle temperature medium, a primary temperature control device for controlling the flow of the high temperature medium and a primary valve; and the secondary heat exchange device comprises a secondary heat exchanger, a low temperature medium, a secondary temperature control device for controlling the flow of the high temperature medium and a secondary valve. The high temperature medium flows back after conveyed into a pipeline of the primary heat exchanger, the middle temperature medium in the primary heat exchanger flows back after heated and conveyed into a pipeline of the secondary heat exchanger, and the low temperature medium in the secondary heat exchange device is heated by a middle temperature medium pipeline to produce steam. The invention further relates to a power generation system of the double heat exchange temperature control device. According to the double heat exchange temperature control device and the power generation system thereof, the temperature differences of the media input into and output from a steam generator can be reduced, so that the steam temperature can be effectively controlled, the service life of a generator set can be prolonged, production accidents can be reduced, and damage to valves and other control elements is reduced.

Description

technical field [0001] The invention relates to a double heat exchange temperature control device and a power generation system thereof, which are widely used in the technical problem of stable heat release required in solar thermal utilization and other thermal energy utilization technologies. Background technique [0002] The existing solar heat storage technology uses molten salt to store heat. Since molten salt is a phase change material, it can output heat stably during the phase change process. Molten salt is a mixture of potassium nitrate (KNO3), sodium nitrite (NaNO2) and sodium nitrate (NaNO3). The high temperature of the solar collector heats the powdered molten salt to a melting point above 142°C, making it recycled in a molten and fluid state. The maximum working temperature can reach a high temperature of 600°C. However, high-temperature molten salt is extremely corrosive to metal materials, and its volume changes greatly during melting and solidification, whi...
