do you know the main structure of the tank?
inner tank (main container)
the inner tank (main container) of the storage tank is mainly composed of an inner suspended ceiling and a supporting reinforcement structure, a cylinder body, a reinforcing ring and a bottom plate, etc., and is fixed on the bottom insulation layer of the foam glass brick and the perlite concrete ring beam through the anchor belt. the gas phase space of the main container is connected with the secondary container, and a ceiling plate is set on the top. an elastic cold insulation layer is arranged outside the cylinder wall to make the inner cylinder expand and contract freely in the radial direction when the temperature difference changes. the buffer layer adopts glass fiber blanket.
outer tank (secondary container)
the outer tank (secondary vessel) is composed of outer top cover, compression ring, cylinder, reinforcing ring, bottom plate, foundation anchor, etc. the secondary vessel is located on the foundation platform as a whole, and the outer tank is fastened on the foundation platform through the anchor belt. the side of the bottom plate adopts a sealing structure to prevent moisture from entering the bottom plate, and the outer top cover adopts a ribbed vault structure composed of i-steel and stiffened plate.
thermal angle protection
the thermal angle protection is set between the inner tank and the outer tank, and is separated from the inner and outer tank by cold insulation material. the cold insulation material is a foam glass brick, and the thermal angle protection is composed of a cylinder plate, an upper annular cover plate and a bottom plate. the wall thickness of the hot angle protection shall be as thin as possible to reduce the tensile crack of the wall plate caused by cold deformation in case of leakage, so as to prevent the leaked low-temperature liquid from directly contacting the cylinder plate of the secondary container and avoid frosting and large amount of evaporated gas of the secondary container.
the bottom insulation layer is divided into two upper floors and upper parts. the upper insulation material is pearlescent sand concrete ring beam and foam glass brick. at the same time, in order to ensure the uniform force of the foam glass brick, a concrete leveling layer is laid under the insulation layer of the glass brick, and a concrete load distributing plate is arranged on the top of the glass brick insulation layer. the lower insulation foam foam glass brick, which is laid under the pearlescent concrete ring beam is high strength foam glass brick, the rest is laid on ordinary strength foam glass brick. similarly, the concrete leveling layer is laid on the top of the foam glass tile, and concrete load distribution board is laid on the top of the foam glass brick. the insulation materials of the interlayer insulation layer are elastic felt and pearlescent sand. the top insulation layer is the upper space of the inner tank ceiling plate, and the insulation material is glass wool.
