Embodiment
[0032] This embodiment provides a heat curing treatment system for absorbing coatings, please refer to figure 1 , this heat-curing treatment system for absorbing paint includes a heat absorber 1 and a hot air supply structure for the heat absorber;
[0033] The hot air supply structure for the heat absorber is used to provide hot air to the tube panel of the heat absorber 1, and the hot air heats up the absorbing paint on the tube panel of the heat absorber 1 to quickly solidify.
[0034] Specifically, the hot air supply structure for the heat absorber includes a hot blast stove 4, a circulating fan 5, an air supply duct 13 and a return air duct 16;
[0035] The hot blast stove 4 is used to heat the gas, and the heated gas is sent to the tube panel of the heat absorber 1 through the air supply duct 13;
[0036] The gas passing through the tube panel flows back to the hot blast stove 4 through the return air duct 16, and enters the next cycle after being reheated in the hot bl...

The invention provides a hot air supply structure for a heat absorber and an absorbing coating heating and curing treatment system, and belongs to the field of photo-thermal power generation. The hot air supply structure comprises a hot-blast stove, a circulating fan, an air supply pipeline and an air return pipeline; the hot-blast stove is used for heating gas and feeding the heated gas into the heat absorber through the air supply pipeline; the gas penetrating through the heat absorber flows back to the hot-blast stove through the air return pipeline; and the circulating fan is arranged on the air supply pipeline and / or the air return pipeline. On-site coating work of the coating can be achieved, a tube panel does not need to be disassembled, assembled and returned to a factory for treatment, the on-site workload is reduced, and the cost is reduced. Curing treatment of the coating on the surface of the tube panel is realized from inside to outside through introduction of hot air, so that evaporation and smooth volatilization of volatile components on the inner layer of the coating can be ensured, and blocked bubbles and flaws are reduced to ensure the curing quality; high-temperature vitrification of the coating on the surface of the tube panel is realized through on-site heliostat field regulation and control by the aid of incident light spots of a heliostat, so that the thermal impact resistance of the coating is improved.
Description
technical field [0001] The invention relates to the field of photothermal power generation, in particular to a hot air supply structure for a heat absorber and a heating and curing treatment system for absorbing coatings. Background technique [0002] In the tower solar thermal power generation system, the heat absorber arranged on the top of the heat absorbing tower is one of the core equipment to realize the light-to-heat conversion of the power station. It is of great significance to improve the thermal efficiency, improve the heat collection capacity of the concentrating heat collection system, and finally increase the annual power generation of the power station. As far as the heat absorber is concerned, the following two methods are usually adopted. One is to lay a reasonable thermal insulation structure on the backlight side of the heat absorber to reduce the heat dissipation of the heat absorber; Covering with black high-temperature absorbing paint, such as Pyromark...
