Description

Technical Field

[0001] The invention relates to the field of transportation safety technology, and in particular to a transportation safety assessment method for an aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container. Background Art

[0002] Hydrogen energy has the characteristics of high energy conversion efficiency, eco-friendliness, and terminal zero emission. With the continuous growth of hydrogen demand, it has become an urgent need to build a strong hydrogen storage and transportation infrastructure between cities and hydrogen-related comprehensive energy demonstration parks. Therefore, it is necessary to develop advanced hydrogen transportation technology to ensure a safe and efficient hydrogen supply.

[0003] At present, for medium-range or short-range hydrogen storage and transportation with a transportation mileage of less than 200km, the widely used hydrogen storage and transportation method is to pressurize the hydrogen and store it in a tube bundle container, and then transport it by a long tube trailer.

[0004] At present, the existing tube bundle container design, manufacturing, and safety methods on the market are mostly based on steel seamless hydrogen tube bundle containers, and there are few operating cases of aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers for public reference. Aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers should use hydrogen storage bottles of the same material, nominal working pressure, and rated water volume; in addition, the technical solutions of aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers are essentially different from those of steel seamless hydrogen tube bundle containers, for example: the diameter-to-length ratio of loading and unloading gas pipes should not be greater than 1:60; there should be sufficient gaps between the gas cylinders loaded in aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers, and no contact is allowed. This makes it difficult to use existing safety assessment technologies to meet the needs of safe on-road applications of long-tube trailers carrying aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers. Summary of the invention

[0005] In view of this, the present invention provides a method for transporting a container with an aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle, so as to solve the problem that the existing safety assessment technology is difficult to meet the demand for safe road application of long tube trailers carrying containers with aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundles.

[0056] At present, the research on the safe application of long-tube trailers carrying aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers is mainly aimed at the hydrogen loading process of the gas cylinders loaded on the hydrogen tube bundle containers on the trailers, but less attention is paid to the hydrogen loading and pressure-maintaining transportation process of the gas cylinders loaded on the hydrogen tube bundle containers; in addition, most of the existing studies analyze a certain loaded gas cylinder on the hydrogen tube bundle container separately, but still lack consideration of the aerodynamic parameter of adjusting the diameter-to-length ratio of the loading and unloading gas pipes, and the reasonable configuration of the intake manifold opening of different gas cylinders loaded on the hydrogen tube bundle container, so as to conduct a safety assessment method for the long-tube trailers carrying aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle containers on the road.

Further, after the hydrogen loading is completed, first obtain the actual distance D between the hydrogen loading place and the destination A Then, according to the average speed V of the trailer under the pressure-maintained transport of the bundled container PM The expected pressure-holding transportation time, i.e. the target transportation time, can be calculated.

[0071] Step S105, based on the hydrogen loading and pressure-maintaining transportation specification parameter set, the first temperature data set and the target transportation time, a transportation safety assessment result of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be assessed is obtained through processing by a preset judgment method.

[0072] Specifically, combined with the hydrogen loading and pressurizing transportation specification parameter set, the first temperature data set and the target transportation time of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated, the transportation safety of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated can be further evaluated and the corresponding transportation safety evaluation results can be obtained.

Therefore, by implementing the present invention, the transportation safety assessment of the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle container can be realized.

[0074] In this embodiment, a method for evaluating the safety of transporting a container with an aluminum alloy liner and a fully wrapped carbon fiber hydrogen tube bundle is provided. Figure 2 : is a flow chart of a method for transport safety assessment of an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0075] Step S201, obtain the hydrogen loading and pressure-maintaining transportation specification parameter set, heat transfer specification parameter set, first temperature data set and second temperature data set of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0076] Step S202, based on the hydrogen loading pressure-maintaining transportation specification parameter set, the heat transfer specification parameter set and the first temperature data set, it is determined whether the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated meets the target hydrogen safety loading conditions.

[0077] Specifically, the above step S202 includes:

[0078] Step S2021, based on the hydrogen loading and pressure-maintaining transportation specification parameter set and the first temperature data set, determine whether the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated meets the initial hydrogen safety loading conditions.

[0079] Specifically, the hydrogen loading and pressure-maintaining transportation specification parameter set and the first temperature data set can be used to preliminarily determine whether the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is affected by the external environment, and then determine whether the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the conditions for hydrogen loading operations, that is, the initial hydrogen safety loading conditions.

[0080] Step S2022: when the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the initial hydrogen safety loading conditions, based on the heat transfer specification parameter set and the first temperature data set, determine whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the target hydrogen safety loading conditions.

[0081] Specifically, when it is preliminarily determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the initial hydrogen safety loading conditions, the heat transfer specification parameter set and the first temperature data set are continued to be used to further determine whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated can perform hydrogen loading operations.

[0082] In some optional implementations, the above step S2021 includes:

[0083] Step a1, obtaining the thermal interaction runaway tolerance coefficient of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0084] Step a2, based on the hydrogen loading and pressure-maintaining transportation specification parameter set and the first temperature data set, calculate the thermal negotiation runaway fluctuation factor of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated.

[0085] Step a3, based on the thermal interaction runaway fluctuation factor and the thermal interaction runaway tolerance coefficient, determine whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated has a thermal interaction runaway phenomenon.

[0086] Step a4: when there is no thermal interaction runaway phenomenon, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the initial hydrogen safety loading conditions.

[0087] Step a5: when there is a thermal negotiation runaway phenomenon, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated does not meet the initial hydrogen safety loading conditions.

[0088] First, the thermal interaction runaway tolerance coefficient θ of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is obtained. NHOC , the thermal interaction runaway tolerance factor θ NHOC =60.

[0089] Secondly, the thermal interaction runaway fluctuation factor θ FHOC It is used to characterize the heat transfer strength between the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated and its external environment, which can be calculated using the following relationship (1):

[0090]

[0091] Where: ΔT a V represents the temperature difference between the air in contact with the gas cylinder in the container with aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle to be evaluated and its surrounding; sw It indicates the instantaneous wind speed (m / s) of the environment where the gas cylinders are loaded in the container with aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle to be evaluated.

[0092] Then, according to the thermal interaction runaway fluctuation factor θ FHOC Thermal interaction runaway tolerance factor θ NHOC It can be determined whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated has thermal exchange runaway due to the external environment.

[0093] Finally, if it is confirmed that thermal interaction out of control occurs, it means that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated does not meet the conditions for safe hydrogen loading, and the external environment of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated should be cooled immediately.

[0094] If it is determined that there is no thermal interaction runaway phenomenon, it can be preliminarily determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the conditions for safe hydrogen loading, and the next step of evaluation can be carried out.

[0095] In some optional implementations, the above step a3 includes:

[0096] Step a31, comparing the thermal negotiation runaway fluctuation factor with the thermal negotiation runaway tolerance coefficient.

[0097] Step a32, when the thermal negotiation runaway fluctuation factor is less than the thermal negotiation runaway tolerance coefficient, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated does not have thermal negotiation runaway phenomenon.

[0098] Step a33, when the thermal negotiation runaway fluctuation factor is greater than or equal to the thermal negotiation runaway tolerance coefficient, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated has a thermal negotiation runaway phenomenon.

[0099] Specifically, the thermal interaction runaway fluctuation factor θ FHOC Thermal interaction runaway tolerance factor θ NHOC For comparison, if the thermal negotiation out-of-control fluctuation factor θ FHOC Less than the thermal interaction runaway tolerance factor θ NHOC , it means that there is no thermal interaction runaway phenomenon in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0100] Furthermore, if the thermal interaction runaway fluctuation factor θ FHOC Greater than or equal to the thermal interaction runaway tolerance factor θ NHOC , it means that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated has thermal exchange runaway phenomenon.

[0101] In some optional implementations, the above step S2022 includes:

[0102] Step b1, when the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the initial hydrogen safety loading conditions, based on the heat transfer specification parameter set and the first temperature data set, calculate the thermal runaway fluctuation factor of the gas cylinder loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0103] Step b2, based on the thermal runaway fluctuation factor and the thermal runaway tolerance coefficient, determine whether the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated has thermal runaway phenomenon in the bottle.

[0104] Step b3, when there is no thermal runaway phenomenon in the bottle, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the target hydrogen safety loading conditions.

[0105] Step b4, when there is a thermal runaway phenomenon in the bottle, it is determined that the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated does not meet the target hydrogen safety loading conditions.

[0106] First, if Figure 3 As shown, the preset first relationship curve is used to represent the thermal runaway tolerance coefficient θ in the bottle NIHOC The ambient temperature T in the first temperature data set aTherefore, combined with the first temperature data set and based on the preset first relationship curve, the thermal runaway tolerance coefficient θ of the gas cylinder loaded in the container with the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle to be evaluated can be obtained. NIHOC .

[0107] Secondly, the thermal runaway fluctuation factor θ FIHOC It is used to characterize the heat transfer strength between the hydrogen in the gas cylinder loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated and the carbon fiber composite wrapping layer on the inner and outer edges of the cylinder before the new hydrogen loading and pressure-maintaining transportation process is started. It can be calculated using the following relationship (2):

[0108]

[0109] Then, according to the thermal runaway fluctuation factor θ FIHOC and the thermal runaway tolerance factor θ NIHOC It can be determined whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated has thermal runaway phenomenon inside the bottle.

[0110] Finally, if it is determined that there is thermal runaway in the bottle, it can be finally determined that the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle container to be evaluated does not meet the conditions for safe hydrogen loading; if it is determined that there is no thermal runaway in the bottle, it can be finally determined that the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle container to be evaluated meets the conditions for safe hydrogen loading.

[0111] In some optional implementations, the above step b2 includes:

[0112] Step b21, comparing the thermal runaway fluctuation factor inside the bottle with the thermal runaway tolerance coefficient inside the bottle.

[0113] Step b21, when the thermal runaway fluctuation factor in the bottle is less than the thermal runaway tolerance coefficient in the bottle, it is determined that the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated does not have thermal runaway in the bottle.

[0114] Step b23, when the thermal runaway fluctuation factor in the bottle is greater than or equal to the thermal runaway tolerance coefficient in the bottle, it is determined that the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated has a thermal runaway phenomenon in the bottle.

[0115] Specifically, the thermal runaway fluctuation factor θ in the bottle is FIHOC and the thermal runaway tolerance factor θ NIHOC For comparison, if the thermal runaway fluctuation factor θ in the bottle FIHOC Less than the thermal runaway tolerance factor θ in the bottle NIHOC , it means that there is no thermal runaway phenomenon in the carbon fiber composite winding layer of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0116] Furthermore, if the thermal runaway fluctuation factor θ FIHOC Greater than or equal to the thermal runaway tolerance factor θ NIHOC , it means that there is thermal runaway in the carbon fiber composite winding layer of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0117] Step S203, when the target hydrogen safety loading condition is met, judging whether the hydrogen loading process of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated is safe based on the first temperature data set and the second temperature data set.

[0118] Specifically, the above step S203 includes:

[0119] Step S2031, when the target hydrogen safety loading condition is met, the aggregate temperature rise fluctuation factor is calculated based on the first temperature data set and the second temperature data set.

[0120] Among them, the lumped temperature rise fluctuation factor is used to characterize the ratio of the loading and unloading gas pipe diameter length P in the hydrogen loading process of the hydrogen test. SA The influence of the temperature rise of the hydrogen in the gas cylinder loaded in the container with aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle and the carbon fiber composite wrapping layer on the inner and outer edges of the cylinder is to be evaluated.

[0121] Specifically, the lumped temperature rise fluctuation factor θ can be calculated using the following equation (3): FLT :

[0122]

[0123] Step S2032: compare the lumped temperature rise fluctuation factor with the preset lumped temperature rise tolerance coefficient.

[0124] Among them, the preset lumped temperature rise tolerance factor θ NLT The value of is 0.75.

[0125] Step S2033: when the lumped temperature rise fluctuation factor is less than the preset lumped temperature rise tolerance coefficient, it is determined that the hydrogen loading process of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated is safe.

[0126] Specifically, when the lumped temperature rise fluctuation factor θ FLT Less than the preset lumped temperature rise tolerance factor θ NLT When , it means that the selected loading and unloading gas pipe diameter-to-length ratio meets the requirements for safe hydrogen loading, that is, the hydrogen loading process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is safe. Among them, the largest diameter-to-length ratio specification among all the alternative loading and unloading gas pipes that meet the requirements can be selected.

[0127] Step S2034: when the lumped temperature rise fluctuation factor is greater than or equal to the preset lumped temperature rise tolerance coefficient, it is determined that the hydrogen loading process of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated is unsafe.

[0128] Specifically, when the lumped temperature rise fluctuation factor θ FLT Greater than or equal to the preset lumped temperature rise tolerance factor θ NLT When , it means that the selected loading and unloading gas pipe diameter-to-length ratio does not meet the hydrogen safety loading requirements, and the hydrogen loading operation should be stopped. That is, the hydrogen loading process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is unsafe.

[0129] In one example, the types of optional loading and unloading gas pipes should be consistent with the total number of rated hydrogen cylinders n. FG Consistent, diameter ratio P SA The specifications are P from small to large. SA1 , P SA2 ,……,P SAnFG .

[0130] Furthermore, the inner peripheral temperature T of the hydrogen storage bottle loaded in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container that just completed a certain test hydrogen loading operation ie T ie1 , T ie2 ,……,T ienFG , peripheral temperature T ce T ce1 , T ce2 ,……,T cenFG .

[0131] Furthermore, combined with the ambient temperature T a , the lumped temperature rise fluctuation factor θ of different gas cylinders loaded in the hydrogen tube bundle container under the conditions of loading and unloading gas pipes with different diameter-to-length ratios can be obtained FLT They are θ FLT1 ,θ FLT2 , ..., θ FLTnFG .

[0132] Furthermore, if all selected path length ratios P SA Under the specification, there are several lumped temperature rise fluctuation factors θ FLT <Preset lumped temperature rise tolerance factor θ NLT =0.75, the hydrogen loading process is tested to be safe, and the largest diameter-to-length ratio specification is selected among all the alternative loading and unloading gas pipes; if all the selected diameter-to-length ratios P SA Under the specification, the lumped temperature rise fluctuation factor θ is obtained FLT are greater than or equal to the preset lumped temperature rise tolerance factor θ NLT=0.75, it means that the selected loading and unloading gas pipe diameter-to-length ratio does not meet the hydrogen safety loading requirements, that is, the hydrogen loading process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is unsafe.

[0133] Step S204: When the hydrogen loading process is safe, the target transportation time of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated is obtained. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0134] Step S205, based on the hydrogen loading and pressure-maintaining transportation specification parameter set, the first temperature data set and the target transportation time, a transportation safety assessment result of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be assessed is obtained through processing by a preset judgment method. Figure 1 Step S105 of the illustrated embodiment will not be described in detail here.

[0135] The method for assessing the transportation safety of an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container provided in the present embodiment introduces a thermal negotiation runaway fluctuation factor and a thermal negotiation runaway tolerance coefficient to conduct a preliminary assessment on whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed can be safely loaded with hydrogen, and can quantitatively characterize the heat transfer phenomenon between the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed and its external environment, and can provide a useful reference for the structural design of the gas cylinder loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container and the reasonable configuration of the cost; at the same time, the thermal runaway fluctuation factor in the bottle and the thermal runaway tolerance coefficient in the bottle are introduced to conduct a secondary assessment on whether the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed can be safely loaded with hydrogen, and can quantitatively characterize the heat transfer phenomenon between the hydrogen in the gas cylinder loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed and the carbon fiber composite winding layer at the inner periphery and outer edge, and can provide a useful reference for the material performance and reasonable configuration of the cost of the gas cylinder loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container. Furthermore, the introduction of the lumped temperature rise fluctuation factor and the preset lumped temperature rise tolerance coefficient can quantitatively evaluate whether the hydrogen loading process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container is safe, and can provide a simple and practical selection reference for the selection of the diameter-to-length ratio of the loading and unloading gas pipes, which to a certain extent improves the operating efficiency of the actual hydrogen loading operation process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container.

[0136] In this embodiment, a method for evaluating the safety of transporting a container with an aluminum alloy liner and a fully wrapped carbon fiber hydrogen tube bundle is provided. Figure 4 : is a flow chart of a method for transport safety assessment of an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0137] Step S401, obtain the hydrogen loading and pressure-maintaining transportation specification parameter set, heat transfer specification parameter set, first temperature data set and second temperature data set of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0138] Step S402: Based on the hydrogen loading pressure-maintaining transportation specification parameter set, the heat transfer specification parameter set and the first temperature data set, determine whether the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated meets the target hydrogen safety loading conditions. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0139] Step S403: When the target hydrogen safety loading condition is met, based on the first temperature data set and the second temperature data set, it is determined whether the hydrogen loading process of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated is safe. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0140] Step S404: When the hydrogen loading process is safe, the target transportation time of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated is obtained. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0141] Step S405, based on the hydrogen loading and pressure-maintaining transportation specification parameter set, the first temperature data set and the target transportation time, a transportation safety assessment result of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be assessed is obtained through processing by a preset judgment method.

[0142] Specifically, the above step S405 includes:

[0143] Step S4051, based on the hydrogen loading pressure-maintaining transportation specification parameter set and the first temperature data set, calculate the hydrogen loading time of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated.

[0144] Specifically, after determining that the hydrogen loading process is safe, the hydrogen loading time of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated can be calculated by combining the hydrogen loading pressure maintaining transportation specification parameter set and the first temperature data set of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0145] Step S4052, based on the hydrogen loading and pressure maintaining transportation specification parameter set, the target transportation time and the hydrogen loading time, a preset judgment method is used to judge whether the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is safe, and a transportation safety assessment result is obtained.

[0146] Specifically, based on the hydrogen loading and pressure maintaining transportation specification parameter set, target transportation time and hydrogen loading time of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated, it can be judged whether the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is safe, and the corresponding transportation safety assessment result can be obtained.

[0147] In some optional implementations, the above step S4051 includes:

[0148] Step c1, based on the hydrogen loading pressure-maintaining transportation specification parameter set and the first temperature data set, the hydrogen density of the gas cylinder loaded in the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated is obtained through a preset second relationship curve.

[0149] Step c2, calculating the nominal hydrogen loading amount based on the hydrogen loading pressure-maintaining transportation specification parameter set and hydrogen density.

[0150] Step c3, calculating the hydrogen loading time based on the hydrogen loading pressure-maintaining transportation specification parameter set and the nominal hydrogen loading amount.

[0151] Among them, Figure 5 As shown, the preset second relationship curve is used to represent the nominal working pressure P N0 The hydrogen density P of the gas cylinder loaded in the container with the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle to be evaluated H2 The corresponding relationship between them.

[0152] Specifically, combined with the ambient temperature T a , and according to the hydrogen loading pressure maintenance transportation specification parameters, the nominal working pressure P is centralized N0 The hydrogen density ρ can be obtained H2 .

[0153] Further, the nominal hydrogen loading M is calculated using the following equation (4): FC :

[0154] M FC =P H2 ·V FC (4)

[0155] Further, the hydrogen loading time T is calculated using the following equation (5): FC :

[0156]

[0157] In some optional implementations, the above step S4052 includes:

[0158] Step d1, calculating the ratio of the target transportation time to the hydrogen loading time.

[0159] Step d2, based on the hydrogen loading and pressure-maintaining transportation specification parameter set, calculate the hydrogen loading degree of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated.

[0160] Step d3, based on the hydrogen loading degree, a lower limit value corresponding to the ratio is determined through a preset third relationship curve.

[0161] Step d4, judging whether the transportation of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be evaluated is safe based on the ratio and the lower limit value, and obtaining a transportation safety evaluation result.

[0162] Specifically, according to the hydrogen loading pressure maintenance transportation specification parameters, the rated total hydrogen filling volume V FG and rated total volume V FC The hydrogen loading degree can be calculated

[0163] Further, if Figure 6 As shown, the third relationship curve is preset to represent the hydrogen loading degree. and the ratio of target transport time to hydrogen loading time The correspondence between the lower limit values ​​of .

[0164] Therefore, combined with the preset third relationship curve, according to the calculated hydrogen loading degree It can be determined The lower limit value of .

[0165] Furthermore, according to this ratio and The lower limit value can be used to determine whether the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is safe, and to obtain the transportation safety assessment result.

[0166] In some optional implementations, the above step d4 includes:

[0167] Step d41, comparing the ratio with the lower limit value.

[0168] Step d42: when the ratio is less than or equal to the lower limit, it is determined that the transportation safety assessment result is that the transportation of the aluminum alloy liner carbon fiber fully-wound hydrogen tube bundle container to be assessed is unsafe.

[0169] Step d43, when the ratio is greater than the lower limit, it is determined that the transportation safety assessment result is the transportation safety of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed.

[0170] Specifically, the ratio of the target transportation time to the hydrogen loading time is and The lower limit of Less than or equal to When the lower limit value is reached, it means that even if the expected hydrogen loading process and pressure-maintaining transportation process are completed, the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is still in the stage of continuous temperature increase, which means that the transportation safety assessment result can be determined as the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is unsafe.

[0171] Furthermore, when the ratio Greater than When the lower limit of , it means that the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated is not continuously heated, and the maximum temperature rise begins to decrease during the pressure-maintaining transportation process, that is, the transportation safety assessment result is determined to be the transportation safety of the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated. Further, in this case, after the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container to be evaluated completes hydrogen loading and pressure-maintaining transportation to the next destination, return to step S401.

[0172] Step S406, when the transportation safety assessment result is that the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed is unsafe, a set of adjacent gas cylinder spacing conditions is obtained.

[0173] When the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container is assessed to be unsafe, further assessment can be carried out.

[0174] Specifically, the heat carried by the hydrogen in the gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated during the loading process will increase the temperature of the air in contact with the periphery of the gas cylinder due to the heat conduction of the solid layer material on the wall of the gas cylinder and the convection heat exchange between the solid layer material on the periphery of the gas cylinder and the peripheral contact air after the hydrogen loading is completed and the pressure-maintaining transportation process is started, thereby inhibiting the heat in the carbon fiber composite winding layer from dissipating to the peripheral contact air to a certain extent. This phenomenon will gradually ease as the spacing between the gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated increases. This also means that as the spacing between the gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated increases, the lower limit of the intake manifold opening difference can also be increased, thereby improving the phenomenon of continuous temperature rise of the carbon fiber composite winding layer caused by the compression effect of the incident hydrogen flow and the negative-coke soup effect during the pressure-maintaining transportation of the hydrogen tube bundle container during hydrogen loading.

[0175] Therefore, when it is determined that the carbon fiber composite winding layer in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated continues to heat up, that is, when it is determined that the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is unsafe, firstly, different adjacent gas cylinder spacing conditions, that is, the adjacent gas cylinder spacing condition set, are obtained.

[0176] Among them, the outer diameter of the gas cylinder loaded in the container with the aluminum alloy liner and carbon fiber fully wrapped hydrogen tube bundle to be evaluated is dce , the distance between the axes of adjacent loaded gas cylinders in the hydrogen tube bundle container d ca , the spacing between adjacent gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated can be obtained.

[0177] Step S407, based on the adjacent gas cylinder spacing condition set, optimizing the configuration of the intake manifold opening of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated.

[0178] The definition of intake manifold opening difference is explained as follows: When the number of gas cylinders loaded in the hydrogen bundle container is known, n FG When calculating the intake manifold opening difference of the gas cylinder in the middle position in the container from the intake manifold opening of all other gas cylinders except the gas cylinder in the middle position in the container, then divide the obtained difference by the number of gas cylinders loaded in the hydrogen tube bundle container, and the obtained value is the intake manifold opening difference.

[0179] Further, if Figure 7 The figure shows the relationship between the intake manifold opening difference and the spacing between the gas cylinders loaded in the hydrogen tube bundle container. It should be noted that the spacing between the gas cylinders loaded in the hydrogen tube bundle container should be sufficient but not too large. According to the engineering experience of production and manufacturing, the value is generally between 30 and 70 mm. Figure 4 It can be obtained that when the spacing between the gas cylinders loaded in the hydrogen tube bundle container is Δ d Intake manifold opening difference Δ IMO .

[0180] Specifically, in combination with the different gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated, a differentiated and reasonable configuration of the intake manifold opening is made under different adjacent gas cylinder spacing conditions, that is, adjacent gas cylinder spacing conditions. This can, to a certain extent, alleviate the threat of thermal failure of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated due to the continuous warming of the carbon fiber composite winding layer.

[0181] The method for assessing the transportation safety of an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container provided in this embodiment can achieve a transportation safety assessment of an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed, based on the safety of the hydrogen loading process of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed, and based on the relative relationship between the target transportation time and the hydrogen loading time of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed. Further, on the basis of determining that the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed is unsafe, the intake manifold opening is differentiated and reasonably configured under different adjacent gas cylinder spacing conditions in combination with the different gas cylinders loaded in the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be assessed, which can alleviate the threat of thermal failure of the hydrogen tube bundle container due to the continuous temperature increase of the carbon fiber composite wrapping layer to a certain extent.

[0182] In one example, the hydrogen loading and pressure-maintaining transportation specification parameters of a certain aluminum alloy liner carbon fiber fully wrapped tube bundle container are given, including: the nominal working pressure P N0 =30MPa, maximum hydrogenation flow rate F RGM =7.2kg / min, maximum hydrogen loading branch number n BR = 3 rows, rated total hydrogen filling volume V FG =7500Nm 3 , Rated total volume V FC =29.7m 3 、Rated total number of hydrogen tanks n FG = 9, inner diameter d of the mouth of the gas cylinder loaded in the hydrogen tube bundle container ci =0.085m, outer diameter of loading gas cylinder d ce = 0.715m, the distance between the axes of adjacent gas cylinders loaded in the hydrogen tube bundle container d ca =0.76m, average speed of trailer under pressure-maintained transport of bundled container V PM =30km / h.

[0183] Given the heat transfer specification parameters of a certain aluminum alloy liner carbon fiber fully wrapped tube bundle container, including: the specific heat capacity Cf of the carbon fiber composite wrapping layer on the inner and outer edges of the tube bundle container loaded with gas cylinders SH =1390J / (kg℃), uniform thermal conductivity Cf of carbon fiber composite wrapping layer around the inner and outer edges of the bottle TC =0.974W / (m℃), the average thickness of the carbon fiber composite winding layer on the inner and outer edges of the bottle is T Cf =15mm, the specific heat capacity of the aluminum alloy liner of the tube bundle container gas cylinder is Al SH =950J / (kg℃), thermal conductivity of aluminum alloy liner inside the bottle Al TC =166.1W / (m℃). The average thickness of the aluminum alloy liner around the bottle is T Al=6mm. Thermal interaction runaway tolerance coefficient θ of tube bundle container NHOC =60; Figure 3 It can be seen that when the ambient temperature T a =24℃, the thermal runaway tolerance coefficient of the tube bundle container is θ NIHOC ≈220.

[0184] Furthermore, the environment V of the gas cylinders loaded in the hydrogen tube container is measured. sw When the wind speed reaches level 3 (about 3m / s), the outer temperature of the hydrogen tube container is T ce0 =36℃, ambient temperature T a = 22°C, i.e. the temperature difference between the gas cylinder and the surrounding air ΔT a =T ce0 -T a =14℃, using the above relationship (1), the thermal interaction runaway fluctuation factor θ of the hydrogen tube bundle container can be obtained FHOC ≈32.2<=60, so proceed to the next step of judgment.

[0185] Furthermore, the above relationship (2) can be used to obtain the thermal runaway fluctuation factor θ of the hydrogen tube container: FIHOC ≈154.9<220, so the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container can be used for hydrogen loading operations.

[0186] Furthermore, the preset lumped temperature rise tolerance factor θ NLT The value is 0.75. The types of optional loading and unloading gas pipes should be consistent with the total number of rated hydrogen cylinders n. FG =9, the diameter ratio P SA The specifications from small to large are 1:250, 1:200, 1:175, 1:150, 1:120, 1:100, 1:80, 1:75, 1:60. The inner peripheral temperature T of the hydrogen storage bottle loaded in the aluminum alloy liner carbon fiber fully wound hydrogen tube bundle container that just completed a certain test hydrogen loading operation ie They are 58℃, 60.4℃, 62.5℃, 64.3℃, 65.8℃, 67.0℃, 68.0℃, 68.7℃, 69.2℃ respectively; the peripheral temperature T ce They are 34.8℃, 35.4℃, 35.7℃, 35.9℃, 36.1℃, 36.2℃, 36.3℃, 36.4℃, 36.4℃ respectively. The ambient temperature is T a = 22℃, the above relationship (3) can be used to calculate the aggregate uncontrolled fluctuation factor θ of different gas cylinders loaded in the hydrogen tube container under the conditions of loading and unloading gas pipes with different diameter-to-length ratios. FLTThey are 0.4625, 0.4855, 0.4996, 0.5102, 0.5198, 0.5258, 0.5279, 0.5301, and 0.5292, respectively, that is, all the selected diameter-to-length ratios P SA Under the specification, all the lumped temperature rise fluctuation factors θ FLT <Lumped temperature rise tolerance factorθ NLT =0.75, so the hydrogen loading process is tested to be safe, and the largest diameter-to-length ratio specification of all alternative loading and unloading gas pipes is selected, that is, 1:60.

[0187] Further, according to the ambient temperature T a =22℃, combined Figure 5 It can be obtained for the nominal working pressure P N0 =30MPa hydrogen tube container, the density of hydrogen in the cylinder loaded is ρ H2 ≈20.8kg / m 3 .

[0188] Furthermore, from the rated total volume V FC =29.7m 3 , combined with the above relationship (4), the nominal hydrogen loading M can be calculated FC ≈617.8kg.

[0189] Furthermore, according to the maximum hydrogenation flow F RGM =7.2kg / min, maximum hydrogen loading branch number n BR = 3 rows, combined with the above relationship (5), the hydrogen loading time T can be calculated FC ≈28.5min.

[0190] Furthermore, considering the actual distance D between the hydrogen loading point and the destination A =45km, average speed of trailer under pressure-maintained transport of bundled container V PM =30km / h, the ratio of the expected pressure-maintaining transportation time to the hydrogen loading time can be calculated The ratio of the expected pressure-maintaining transportation time to the hydrogen loading time can thus be calculated.

[0191] Furthermore, combined with the rated total hydrogen filling volume V FG =7500Nm 3 , Rated total volume V FC =29.7m 3 It can be calculated Further, by Figure 6 It can be seen that the corresponding ratio of pressure-maintaining transportation time to hydrogen loading time is The lower limit of ≈3.62 is the ratio of the expected pressure-maintaining transportation time to the hydrogen loading time. The corresponding ratio of pressure-maintaining transportation time to hydrogen loading time If the lower limit value of is ≈3.62, it is determined that the carbon fiber composite winding layer is still in the stage of continuous temperature increase, that is, it is determined that the transportation of the aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container to be evaluated is unsafe, so the next step of evaluation is carried out.

[0192] Finally, the outer diameter d of the gas cylinder loaded in the hydrogen tube bundle container ce = 0.715m, the distance between the axes of adjacent gas cylinders loaded in the hydrogen tube bundle container d ca = 0.76m, the spacing Δ between the gas cylinders loaded in the hydrogen tube bundle container can be calculated d =0.045m. Further, Figure 7 It can be seen that when the spacing between the gas cylinders loaded in the hydrogen tube container is Δ d = 0.045 when the intake manifold opening difference Δ IMO ≈70°.

[0193] In this embodiment, an aluminum alloy liner carbon fiber fully wrapped hydrogen tube bundle container transportation safety assessment device is also provided, which is used to implement the above embodiments and preferred implementations, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
