Title:
SOLAR THERMAL POWER GENERATION SYSTEM AND HEAT TRANSFER AND OBTAINING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/085712
Kind Code:
A1
Abstract:
A solar thermal power generation system and a heat transfer and obtaining method. The solar thermal power generation system comprises a heat collection device (1), a heat storage device (2), and a conventional island. The heat collection device (1) comprises a high-temperature tank used for storing a high-temperature heat storage medium. The heat storage device (2) comprises at least one storage container and sliding rails (4) connected to the storage container. The conventional island comprises a steam turbine, and a heat obtaining device (3) is connected to the steam turbine. The storage container slides between the high-temperature tank and the heat obtaining device (3) by means of the sliding rails (4), so as to convey the high-temperature heat storage medium from the high-temperature tank to the heat obtaining device (3). The heat transfer and obtaining method comprises: during heat storage, moving a heat storage device (2) to the position of a heat collection system, and storing a high-temperature heat storage medium into the heat storage device (2); and when heat is obtained, moving the heat storage device (2) in which the high-temperature heat storage medium is stored, to the position of a conventional island, and conveying the high-temperature heat storage medium to a heat obtaining device (3) of the conventional island. A heat storage device (2) is used for storage and conveyance, and conveys the heat storage medium between the heat collection device (1) and the heat obtaining device (3) in a reciprocating manner. A pipeline system is replaced by the movable heat storage device (2), accordingly, investment of the pipe system is eliminated, construction costs of a solar thermal power plant are reduced; overhaul and maintenance work of the pipeline system is not needed, and operation costs are reduced. The control complexity and the operation difficulty are greatly reduced.
