Multifunctional giant frame inclined grid industrial structure

Abstract

The invention discloses a multifunctional giant frame inclined grid industrial structure. The structure comprises a giant frame column, an inclined grid, an upper truss beam, a lower truss beam, a combined bottom plate, a combined top plate and a surface skin. A fused salt heat absorber is supported at the top of the structure and is connected to 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; and the structure is provided with an air inlet and outlet layer, and the air inlet and outlet layer is connected to a surface radiator inside the structure, a regenerative system outside the structure, a circulating water pump and the like to jointly form a surface type indirect air cooling system. According to the multifunctional giant frame inclined grid industrial structure, a multifunctional industrial structure scheme is achieved; the problems that a traditional direct cooling system is large in power consumption, an indirect cooling system is large in occupied area, long in construction period, high in initial investment 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. The multifunctional giant frame inclined grid industrial 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 multifunctional giant frame inclined grid industrial structure. Background technique [0002] The tower-type photothermal power generation uses the fixed eyepiece group to gather sunlight to the heat absorber fixed on the top of the tower, which is used to generate high temperature, heat the working fluid to generate superheated steam or high-temperature gas, and drive the 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 direct air cooling sys...

AI Technical Summary

Problems solved by technology

The direct air-cooling system adopts mechanical ventilation, which consumes a lot of power, about 5% of the power generated by light and heat. The large-diameter axial flow fan is noisy, and the system is greatly affected by the ambient wind.

The indirect air-cooling system is equipped with an air-cooling tower, the circulating water system is in a closed state, and the air-cooling power consumption rate is low, but it occupies a large area and requires a large initial investment. The traditional air-cooling tower is built with concrete, and the construction period is long and the overall construction is difficult. And it will become solid waste after being scrapped, and the environmental protection performance is poor
