Embodiment Construction

[0011] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0012] Such as figure 1 As shown, a high-temperature storage tank body structure includes a storage tank base material 1 , an intermediate high-temperature-resistant material 2 and an inner lining layer 3 . The base material 1 of the storage tank is made of carbon steel, the middle high temperature resistant material 2 is a layer of insulating refractory bricks, and the inner lining layer 3 is a stainless steel lining to protect the refractory bricks.

[0013] The thickness of the storage tank base material 1 carbon steel is ≥ 6mm, and its thickness value is determined according to the calculated value of the design paramet...

Abstract

The invention relates to a high-temperature storage tank body structure. The storage tank body structure comprises a storage tank base material, a middle high-temperature-resistant material and a liner layer, wherein the storage tank base material is made of carbon steel, the middle high-temperature-resistant material is a layer of insulation refractory bricks, and the liner layer is a stainless steel liner protecting the refractory bricks. The high-temperature storage tank body structure can effectively isolate the storage tank base material from making contact with high-temperature liquid, greatly reduces amount of expensive stainless steel, meanwhile, meets the requirements for high temperature resistance and corrosion resistance and greatly reduces equipment investment.

Description

technical field [0001] The invention relates to a tank body, in particular to a tank body structure of a high-temperature storage tank in the field of solar thermal power generation and the field of chemical industry. Background technique [0002] In solar thermal power generation, there is usually a demand for energy during periods of no solar radiation, so when the heat collection field cannot collect energy, the energy storage system must deliver energy to the system to meet the demand. One means of energy storage involves the sensible heat of heat transfer fluids, especially molten salts. During the period of solar radiation, the molten salt is heated by the heat collection field to store heat energy, so that during the period of no solar radiation, the molten salt is pumped from the storage tank and passed through the heat exchanger to replace the heat energy in the high-temperature molten salt to Meet energy needs during periods of no solar radiation. In practice, in...
