Abstract

The multi-mode tower solar thermal power generation device of the present invention adopts a special ceramic solar receiver, replaces heat transfer and heat storage media such as heat transfer oil or molten salt with "quick sand", and realizes supercritical carbon dioxide Brayton heat with the help of sensible heat and high-temperature radiation carried by quicksand Power generation; on the basis of innovative molten salt heat storage technology, it has realized complementarity with technologies such as organic Rankine thermal power generation, lithium bromide air conditioning, and biomass energy, and has made great achievements in reducing cooling water, reducing costs, extending power generation hours, and expanding the scope of use. A bold attempt has been made to lay the technical foundation for the ultimate replacement of fossil energy power generation. The device belongs to the technical field of solar thermal power generation.

Description

technical field [0001] The multi-mode tower solar thermal power generation device of the present invention takes into account different heat transfer media, adopts an innovative solar receiver, and adds a complementary technology with biomass energy on the basis of maintaining the technology of molten salt heat storage. There have been major technological breakthroughs in terms of cost, extension of power generation hours, and expansion of the scope of use. The device belongs to the technical field of solar thermal power generation. Background technique [0002] The most prominent advantage of the Brayton cycle thermal power generation technology is the high thermoelectric conversion efficiency of the system. Air, helium, and carbon dioxide are mainly used as power working fluids, and high-temperature thermal energy is provided by fuel, gas, nuclear energy, and solar energy for operation. Obviously, this technology will have good application prospects not only in the fields...
