Description
Technical Field
[0001] This disclosure pertains to the field of hydrogen energy technology, and particularly relates to a design method, system, equipment, medium, and product for an insulation jacket of a liquid hydrogen storage tank. Background Technology
[0002] In high-vacuum multilayer insulated liquid hydrogen storage tanks used for liquid hydrogen production, the significant temperature difference between the liquid hydrogen stored inside the tank and the external environment leads to continuous leakage of cold energy due to heat conduction, convection, and radiation effects. Therefore, as the core equipment for liquid hydrogen storage, the insulation design performance of the high-vacuum multilayer insulated storage tank directly determines the energy efficiency and operational stability of the hydrogen production system.
[0003] In existing publicly available technical solutions, the insulation design of high-vacuum multilayer insulated liquid hydrogen storage tanks often focuses only on the three core components (or their combination) of the inner tank, outer tank, and insulation jacket. The thermal behavior of other key components is often simplified or ignored, resulting in insufficient accuracy in heat transfer modeling and difficulty in supporting high-precision optimization and prediction of real operating conditions.
[0004] Therefore, in the research on insulation design of liquid hydrogen storage tanks, insulation interlayer modeling is a key bottleneck problem. Summary of the Invention

This method systematically incorporates the geometric parameters and material properties of various structural components of the liquid hydrogen storage tank, which may affect the heat transfer effect, into a global optimization framework for the insulation design of the liquid hydrogen storage tank. These parameters are modeled as key variables affecting the overall thermal performance, thereby achieving a synergistic improvement in the accuracy of the insulation structure design and the prediction of the internal dynamic heat transfer behavior of hydrogen.

Obviously, the drawings described below are some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0021] Figure 1 A schematic diagram of the liquid hydrogen storage tank in an embodiment of this disclosure is shown. The liquid hydrogen storage tank mainly includes an outer tank 1, an inner tank 2, a high-vacuum multilayer insulation jacket 3, an inner tank support 4, a filling / draining pipe 5, a liquid level sensor 6, a vaporizer 7, and a vent pipe 8. The insulation jacket 3 is disposed between the outer tank 1 and the inner tank 2; the inner tank support 4 is fixed to the inner wall of the outer tank 1, penetrates the insulation jacket, and extends into the inner tank; the filling / draining pipe 5 and the vent pipe 8 respectively penetrate the inner liner of the inner tank and extend through the insulation jacket to the outside of the outer tank, wherein the filling / draining pipe 5 is located at the bottom of the liquid hydrogen storage tank, and the vent pipe 8 is located at the top of the liquid hydrogen storage tank; the liquid level sensor 6 is vertically installed in the inner liner of the inner tank, and its auxiliary wire extends through the insulation jacket to the outside of the outer tank; the vaporizer 7 is installed in the inner liner of the inner tank near the bottom, and its auxiliary wire extends through the insulation jacket to the outside of the outer tank. To ensure insulation performance, filling / draining pipes 5 and auxiliary wires should avoid protruding vertically from the outer tank and should extend along the inside of the insulation interlayer.
[0022] First, the thermal conduction effect of the components of the liquid hydrogen storage tank cannot be ignored, and it has a significant impact on the overall heat transfer performance, such as: 1) Inner tank support component, used for positioning support between outer tank and inner tank, penetrates the insulation interlayer and extends into the interior of inner tank, forming an efficient heat conduction path; 2) The filling / draining pipes penetrate the outer tank wall, the insulation jacket, and the inner tank liner of the storage tank, and are directly exposed to the high temperature difference environment, forming a heat transfer path; 3) The vaporizer and level sensor are arranged inside the tank, and the internal heat conduction path is prone to forming a "heat flow bridge". 4) The vent pipe passes through the outer tank, the insulation jacket and the inner tank, and extends into the inner liner to form a heat transfer path.
[0023] Furthermore, the insulation interlayer is a key component for achieving the intended function, its role being to maintain the cryogenic environment of the inner tank and ensure the stable storage of liquid hydrogen. For liquid hydrogen storage tanks intended for use in renewable energy hydrogen production-hydrogen storage projects and large-scale industrial hydrogen systems, the outer tank volume is used as a fixed design benchmark. The number of insulation interlayer layers per unit length (layer density) and the number of reflective layers per unit length are also fixed. Increasing the thickness of the insulation interlayer will directly compress the effective space of the inner tank, thereby reducing the maximum storable hydrogen mass.
[0024] The insulation interlayer design in this embodiment should achieve multiple adaptive requirements of "maximizing the hydrogen storage capacity of the inner tank" and "lightening the overall tank" while maintaining an acceptable level of heat loss. Therefore, the thickness of the insulation interlayer cannot be determined at the initial design stage, but is an optimization variable resulting from the interplay between the two major factors of "inner tank space" and "structural mass".
[0025] To achieve accurate modeling and optimization of the maximum storable hydrogen mass, the embodiments of this disclosure propose a dual-constraint collaborative analysis framework: First, the two core constraints affecting the maximum storable hydrogen mass are identified and quantified respectively—the relative space of the inner tank and the relative mass of the outer tank; second, the corresponding first and second maximum storable hydrogen masses are independently fitted based on their respective constraints; finally, through the game mechanism between the two, the final optimal maximum storable hydrogen mass is output, and the optimal thickness parameter of the insulation interlayer is ultimately determined accordingly.
[0026] Figure 2 A schematic flowchart illustrating a design method for an insulation jacket of a liquid hydrogen storage tank according to an embodiment of the present disclosure is shown.
[0027] like Figure 2 As shown in the figure, a design method for the insulation jacket of a liquid hydrogen storage tank according to an embodiment of this disclosure includes the following steps: S1, Construct a structural volumetric efficiency constraint system model.
[0028] S11, Construct a structural volumetric efficiency model.
[0029] From a macro perspective, the larger the usable space inside the tank, the higher the maximum hydrogen mass that can be stored. However, the outer tank wall and related accessories of the liquid hydrogen storage tank are necessary components for the integrity and structural load-bearing capacity of the liquid hydrogen storage tank, essentially constituting a "structural encroachment" on the total enclosed space of the inner tank.
[0030] Therefore, to reflect the effective utilization of the internal tank space under structural constraints, the structural volumetric efficiency E is...SV Defined as a parameter characterizing the relative space within the inner tank: E SV = , Among them, V eot V is the total volume of the liquid hydrogen storage tank; OTS V is the volume of the outer tank wall layer; IS V represents the volume of the inner tank support components. VP V represents the volume of the carburetor. ILS V represents the volume of the liquid level sensor. IAW V represents the volume of the auxiliary wires (including insulation) for the vaporizer and level sensor; FDP V represents the volume of the filling / draining pipe. VL This refers to the volume of the vent pipe. All volumes are in meters (m). 3 .
[0031] In this embodiment, V eot Specifically, it refers to the maximum external volume including the tank body and all accessories.
[0032] S12, constructing structural volumetric efficiency E SV With the first maximum storable hydrogen mass M hs1 The relational model.
[0033] Based on extensive experimental data analysis, such as Figure 3 As shown, in this embodiment, the structural volumetric efficiency E SV As a characterization of the first maximum storable hydrogen mass M hs1 The variables of the constraints, With E SV It follows an approximately normal distribution: , Among them, M tw This is the empty weight of the liquid hydrogen storage tank; a , b , c , d , e These are the empirically fitted parameters.
[0034] Empty weight is defined as the mass of a liquid hydrogen storage tank under no medium and at its nominal operating pressure. SV There is a certain range of variation; it cannot be too large or too small. If it is too large, it does not conform to reality; if it is too small, it does not conform to the manufacturing standards for storage tanks.
[0035] S2, construct a model of the relative mass constraint system of the outer tank.
[0036] S21, Construct a relative mass model of the outer tank.
[0037] Apart from the inner tank support components, the layout of other key accessories (including four categories: filling / draining pipes, liquid level sensors, vaporizers, and venting pipes) is mainly constrained by the number of tank interfaces, safety redundancy design, and local structural strength requirements. Their configuration is less sensitive to the size of the tank and has a relatively independent layout logic.
[0038] The design of the outer tank wall and inner tank support components is mainly driven by basic mechanical properties such as external pressure stability and dynamic load response. They belong to the basic structural category of the system, and their mass is positively correlated with the scale of the storage tank, which can directly reflect the compactness and integration level of the overall structure.
[0039] To eliminate the impact of functional accessories and focus on the lightweight nature of the basic structure, thus more accurately reflecting structural compactness and mass efficiency, this embodiment introduces the relative mass of the outer tank: , Among them, M OTS For the outer tank wall layer mass; M IS For the mass of the inner tank support components; M tw This represents the empty weight of the liquid hydrogen storage tank.
[0040] S22, Construct the relative mass R of the outer tank COIT With the second maximum storable hydrogen mass M hs2 The relational model.
[0041] Based on extensive experimental data analysis, such as Figure 4 As shown, the relative mass R of the outer tank COIT As a characterization of the second maximum storable hydrogen mass M hs2 The variables of the constraints, It follows an approximately "inverse" normal distribution: , in, f , g , h , k These are the parameters for empirical fitting; m , n These are experience points.
