Embodiment 1
[0040] see figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , as an example only.
[0041] Such as Figure 1-5 As shown, a ventilation and heat absorbing tower structure includes radial thin-wall columns 1, thin shell walls 2, ring beams 3, surface skin 4, herringbone support 5, equipment layer 6, transfer layer 7 and combined roof 8, and set Molten salt heat sink 9.
[0042] The radial thin-walled columns 1 are evenly arranged along the ring direction of the tower, 8 to 16 in total, running through the overall structure, and adopt reinforced concrete thin-walled columns.
[0043] The ventilation and heat-absorbing structure is provided with an air inlet layer 11, which is connected to the ventilation device outside the structure, and an air outlet layer 10 is provided to form a natural ventilation direct air cooling system together.
[0044] There are 4 to 6 thin shell walls 2, which are arranged at intervals between one radial thin-walled column in the range ...

The invention discloses a ventilation heat absorption tower which comprises radial thin-wall columns, a thin shell wall, an annular beam, a surface skin, a herringbone support, an equipment layer, a conversion layer and a combined top plate. The top of the tower structure supports a fused salt heat absorber and is connected with a fused salt pipeline, a cold fused salt tank, a hot fused salt tank and a steam generator in the structure to jointly form a heat absorption system; the structure is provided with an air inlet layer which is connected with a ventilation device outside the structure and is provided with an air outlet layer, a natural ventilation direct air cooling system is jointly formed, a ventilation heat absorption tower structure scheme is achieved, and the problems that a traditional direct cooling system is large in power consumption and an indirect cooling system is large in occupied area, long in construction period, high in construction cost and the like are solved; meanwhile, the structure is large in overall rigidity and good in stability performance, and the limit value of tower top sunlight gathering on structure displacement is easily met; and the ventilation heat absorption tower structure can be widely applied to tower-type photo-thermal power generation areas with different wind loads and seismic intensities.
Description
technical field [0001] The invention belongs to the technical fields of civil engineering and energy and power engineering, and in particular relates to a ventilation heat absorption tower structure. Background technique [0002] Tower-type photothermal power generation uses a heliostat group to gather sunlight to a heat absorber fixed on the top of a heat-absorbing tower, which is used to generate high temperature, heat molten salt, generate hot steam or high-temperature gas, and drive a steam turbine generator set to generate electricity. Common tower-type photothermal power generation areas include turbine room area, heat storage and exchange and steam generator area, cooling facility area, water treatment and water supply facility area, sewage and wastewater facility area, and heat absorption tower. [0003] Most existing cooling facilities use air cooling, including direct and indirect air cooling systems. The traditional direct air cooling system uses mechanical venti...
