Abstract
The utility model relates to a melting and anti-condensation device of solar photo-thermal power generation phase-change energy storing media. When the solar photo-thermal power generation phase-change energy storing media are subjected to initial melting, high-temperature air provided by a heat supply system enters a coiler through a pipeline to transfer heat and melt the phase-change energy storing media in a heat storage tank body. When the energy storing media have temperature stratification, condensing and freezing, heat storage phase-change materials in the heat storage tank body are led to be even in temperature under effect of convection or mechanical mixed flow, and accordingly the problems such as temperature stratification, condensing and freezing of the phase-change energy storing materials in the heat storage tank body are solved. The melting and anti-condensation device is clean, safe and efficient and achieves the purpose of melting and anti-condensation of the solar photo-thermal power generation phase-change energy storing media.
