Abstract
A tower-type solar thermal power absorber set comprises an upper absorber, a lower absorber and a vapor-water separator; the upper absorber and the lower absorber of peripheral type are externally arranged from top to bottom in the height-wise direction; the vapor-water separator is arranged between the upper absorber and the lower absorber. The outside of the upper absorber is covered with an upper absorber outer glass cover. The outside of the lower absorber is covered with a lower absorber outer glass cover. Reflected sunlight reaches heat-absorbing tubes of the upper absorber through the upper absorber outer glass cover and reaches heat-absorbing tubes of the lower absorber through the lower absorber outer glass cover; the vapor-water separator discharges vapor-water mixture to the lower absorber through a downcomer; the vapor-water mixture reflows to the vapor-water separator through a vapor-water mixture connection tube; a vapor outflow tube of the vapor-water separator discharges saturated vapor to the upper absorber; the saturated vapor is discharged through a superheated vapor outflow tube of the upper absorber. The tower-type solar thermal power absorber set has the advantages that heat loss by radiation and convection is reduced for the peripheral tower-type absorbers, temperature and efficiency of the absorbers are increased, focusing of reflectors is easier to control, and accurate and uniform focusing is easily achieved for a system.
