Problems solved by technology

In the third-generation tower power station technology, the maximum temperature of the storage / heat exchange medium is at least 700°C, so a new type of molten salt heat exchanger is required to meet the temperature requirements; (2) using Brayton cycle power generation technology, supercritical carbon dioxide is used As a heated working medium, but the existing molten salt heat exchanger (the heated side is water) can no longer fully match it

Embodiment

[0036] Please refer to figure 1 , a reverberation-disturbance heat exchanger used in a tower-type photothermal power station. This heat exchanger includes a tank body 4 with openings at both ends. The present invention does not specifically limit the shape of the tank body 4. In this embodiment, Take a horizontal tank as an example. This horizontal tank is a cylindrical tank, that is, the left and right ends of the tank 4 are open. head 1.

[0037] In this embodiment, the inlet head 6 is provided with a first heat exchange medium inlet 7 and a sound wave for supercritical carbon dioxide entering the heat exchanger through the first heat exchange medium inlet 7. The main sound wave generating device 8, the initial area for generating carbon dioxide pulsating flow is formed in the inlet head 6. When the heat exchanger is in operation, the first heat exchange medium enters the inlet head 6 from the first heat exchange medium inlet 7, and the reverberation disturbance generated ...

Abstract

The reverberation disturbance type heat exchanger for the tower type photo-thermal power station comprises a tank body, an inlet end socket and an outlet end socket are arranged at the two ends of the tank body respectively, and a first heat exchange medium inlet and a main sound wave generating device are arranged on the inlet end socket; a second heat exchange medium inlet and a second heat exchange medium outlet are formed in the tank body, a heat exchange pipe is arranged in the tank body, and the second heat exchange medium inlet is communicated with the second heat exchange medium outlet through the heat exchange pipe; and a first heat exchange medium outlet is formed in the outlet sealing head. The heat exchange efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, in particular to a reverberation disturbance heat exchanger used in a tower type solar thermal power station. Background technique [0002] In a solar tower solar thermal power station, in order to achieve continuous and stable output of electricity, a heat storage / heat exchange system is essential. Since the photothermal power generation technology is in the third generation, the power generation and heat storage temperature are required to be greatly increased, which also promotes the application of new storage / heat exchange technologies, especially the supercritical carbon dioxide Brayton cycle technology has begun to be used in photothermal Power system. [0003] In order to adapt to the development of new technologies, heat exchangers that match the heat transfer of supercritical carbon dioxide and molten salt, molten metal, etc. need to be researched emphatically. T...
