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
The present invention relates to a kind of tank body, the high temperature Tank body structure in especially a kind of solar light-heat power-generation field and chemical field.
Background technology
In photo-thermal power generation, do not have solar radiation during conventionally for the demand of energy, so when heat collecting field can not harvest energy, closed-centre system will be to system conveying capacity to meet described demand.A kind of mode of stored energy comprises the sensible heat of heat-transfer fluid, especially the sensible heat of fused salt.During solar radiation, by heat collecting field, heat fused salt and store heat energy, so that during without solar radiation, from storage tank, utilize pump extract fused salt and pass through heat exchanger, by the heat energy displacement in high-temperature molten salt out, to meet without the energy requirement during solar radiation.In practice, in order to improve efficiency of energy utilization and the generating total amount in power station, need to improve pressure, temperature and the flow of steam turbine admission port steam, these requirements increase fused salt quality in the closed-centre system at solar energy thermal-power-generating station, increase in temperature (500～600 ℃, even higher).Closed-centre system, especially the high temperature storage tank in double-pot type closed-centre system, storage tank metallic material is on active service for a long time under this temperature conditions, material internal stress build up, mechanical characteristics declines, in addition the high temperature corrosion of fused salt environment, causes storage tank stress corrosion crack thus, cannot meet long-acting, safe, the stable design objective of solar light-heat power-generation.Above-mentioned these conditioned disjunctions require fused salt storage tank tank body material to propose very high requirement.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of high temperature Tank body structure, can effectively isolate contacting of storage tank base material and high-temp liquid, greatly reduce expensive corrosion-resistant steel consumption, met the requirement of corrosion-and high-temp-resistant simultaneously, greatly reduced equipment investment expense.
The technical solution adopted in the present invention is: a kind of high temperature Tank body structure, comprise storage tank base material, middle high-temperature-resistant layer and inside liner, and described storage tank base material is carbon steel, thickness is more than or equal to 6mm; Described middle high-temperature-resistant layer is insulated fireproof brick; Described inside liner is stainless sheet steel liner, and thickness is 0.1～4mm.
Storage tank base material of the present invention does not directly contact high-temp liquid, and the high temperature resistant degree of described carbon steel is more than or equal to 400 ℃, still can use carbon steel to make when storage tank stores fluid temperature surpasses 400 ℃.
According to actual conditions and design requirement, select, storage tank tank body of the present invention is circular or square or polygon.
The invention has the beneficial effects as follows: the feature with corrosion-and high-temp-resistant, adopt the mode of storage tank base material, middle high temperature material and inside liner, effectively isolate contacting of high-temperature molten salt and carbon steel sheet, in the time of the safe handling that improves equipment, greatly reduce the cost of equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
In figure: 1, storage tank base material carbon steel; 2, middle fire brick; 3, stainless steel inner lining layer.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of high temperature Tank body structure, comprises storage tank base material 1, middle high temperature material 2 and inside liner 3.Wherein storage tank base material 1 is made by carbon steel, and middle high temperature material 2 is one deck insulated fireproof bricks, and inside liner 3 is stainless steel inner linings of protection fire brick.
Thickness >=the 6mm of storage tank base material 1 carbon steel, its one-tenth-value thickness 1/10 is determined according to the calculation of design parameters value of high-temperature tank.
The one-tenth-value thickness 1/10 of middle high temperature material 2 fire brick carrys out value according to the fluid temperature of high-temperature tank physical holding of the stock.
Because stainless steel inner lining layer 3 is mainly to play protection fire brick to sustain safely hot pressing, prevent that the liquid storing in high temperature storage tank from contacting with fire brick, plays corrosion-proof effect.Therefore corrosion-resistant steel adopts the thin plate of 0.1～4mm.
Just the specific embodiment of the present invention of describing in above specification sheets, various casehistorys are not construed as limiting flesh and blood of the present invention, person of an ordinary skill in the technical field read after specification sheets can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
