Multi-directional earthquake resistant heat absorbing tower molten salt tank

Abstract

This invention relates to the field of heat absorption tower engineering technology, and discloses a molten salt tank for a heat absorption tower resistant to multi-directional earthquakes, comprising a swing-type molten salt tank and a self-resetting hybrid energy-dissipating molten salt tank support. The swing-type molten salt tank has shear keys and annular flanges; the self-resetting hybrid energy-dissipating molten salt tank support includes a base, metal-laminated rubber, and a self-resetting hybrid energy-dissipating component. This energy-dissipating component has a ring spring assembly and a slotted steel plate, which sequentially pass through the base, metal-laminated rubber, and flanges and connect them. This invention amplifies the deformation effect through a swing mechanism, concentrates plastic deformation on the energy-dissipating device, and effectively reduces the dynamic response of the molten salt tank under multi-dimensional earthquakes by utilizing multi-stage energy dissipation and self-resetting functions. It solves the problems of insufficient energy dissipation, large residual deformation at the connection points after earthquakes, and poor adaptability to multi-dimensional earthquakes in traditional rigid support structures.
