Description

Technical Field

[0001] The present application relates to the technical field of ship design, and in particular, to a method and device for serial washing of a ship piping system, and related products. Background Art

[0002] In the field of shipbuilding, the piping system plays a vital role as the "lifeline" of the ship. It is responsible for the transmission and heat exchange of water, oil, steam, gas and other media inside the ship and between systems, ensuring the normal operation and efficient coordination of various ship systems. Among them, the oil flow system is a key component, and its performance directly affects the power, economy and reliability of the ship. However, before the oil flow system is put into actual operation, it must go through a crucial link - series washing, to ensure that the cleanliness of the pipeline meets the design requirements and avoid system failure or performance degradation due to residual impurities.

[0003] At present, the domestic shipbuilding industry faces many challenges in the series cleaning of oil flow systems. First, due to the lack of quantifiable control indicators and scientific process control mechanisms, shipyards often rely on experience to determine the series cleaning time when performing series cleaning of oil flow pipelines such as fuel, lubricating oil, and hydraulic oil. This method is not only difficult to ensure the consistency of the series cleaning effect, but also easily leads to problems of excessive or insufficient cleaning, which in turn affects the overall performance and life of the system.

[0004] Secondly, the oil flow pipeline characteristics of different ship types and systems are different, and the requirements for series washing are also different. However, in actual operation, due to the lack of unified judgment basis and standardized operation procedures, there are often large subjective differences between different engineering personnel, which makes it more difficult to control the series washing cycle. This not only increases the difficulty of arranging auxiliary processes, but may also lead to waste of resources such as personnel and consumables, as well as excessive man-hours for coordinating tests.

[0005] What is more serious is that since the washing cycle is difficult to accurately estimate and control, it often has an adverse impact on the overall construction progress of the ship. In a market environment where the ship construction cycle is getting shorter and shorter, any delay in any link may lead to a delay in the delivery time, thereby increasing the cost risk of the shipyard and the risk of reduced market competitiveness. Summary of the invention

[0020]

[0022]

[0023] The time from the start of the series washing until the concentration in the fuel tank after passing through the second filter is less than or equal to the pollutant concentration corresponding to the target level is recorded as t5, and t5 satisfies the formula

[0047] The following is a detailed description of a ship piping system series washing method, device and related products of the present application in conjunction with the accompanying drawings.

[0048] Figure 1 The following is a flow chart of a method for serial washing of a ship piping system in one embodiment of the present application. Figure 1 As shown, the ship pipeline system serial washing method of the embodiment of the present application includes the following steps:

[0049] The pollution level of pollutants in the ship's pipeline system is obtained. If the pollution level of pollutants is greater than the target level, the ship's pipeline system is washed in series. In one embodiment, the ship's pipeline system includes a ship's pipeline and an oil tank connected in series with the ship's pipeline. The present application sets a plurality of pollutant concentration monitoring points in the ship's pipeline system, and the pollution level can be judged according to the proportion of the number of pollutant particle sizes in the ship's pipeline (i.e., the pollution concentration) or the proportion of the number of pollutant particle sizes in the oil tank connected in series with the ship's pipeline. The degree of pollution is characterized by the NAS standard, and online measuring equipment is used to obtain real-time NAS (National Aerospace Standard 1638) standard level data for each branch of the ship's pipeline system. For example, a monitor that can measure the size and number of particles in real time can be selected, or a sensor that monitors multiple parameters at the same time, such as particle concentration, particle size distribution, etc., can be selected, and these data can be converted into NAS levels through algorithms or software.

[0050] Furthermore, the aforementioned target level can be determined according to the specific usage scenario of the ship pipeline system. For example, the target level can be set to level 8, level 6 or level 4. If the pollution level of pollutants in the ship pipeline system is less than or equal to the target level, it indicates that the oil flow quality of the ship pipeline system has met the requirements, and the ship pipeline system has ended the series washing or does not need series washing. If the pollution level of pollutants in a branch of the ship pipeline system is greater than the target level, it indicates that the ship pipeline system needs to be washed. It can be understood that the target level of the aforementioned ship pipeline system is only exemplary and not restrictive. When designing the target level, those skilled in the art can design it specifically according to the different uses of the oil flow medium.

[0051] In one embodiment, Figure 2As shown, the aforementioned ship pipeline system series washing method also includes obtaining the Reynolds number of the oil flow in the ship pipeline system, and comparing the Reynolds number of the oil flow with the critical Reynolds number. When the Reynolds number of the oil flow is greater than the critical Reynolds number, the subsequent steps are continued. When the Reynolds number of the oil flow is greater than the critical Reynolds number, it indicates that the oil flow in the ship pipeline system is in a turbulent state, which can exert a greater force on the inner wall of the ship pipeline system, increase the complexity of the movement of the oil flow in each branch, and improve the series washing quality and efficiency. In a specific embodiment, the aforementioned critical Reynolds number is 4000. When the Reynolds number of the oil flow in the ship pipeline system is less than or equal to the critical Reynolds number, the Reynolds number of the oil flow can be increased by adjusting the temperature of the oil flow or adjusting the number of stages of the filter system set in the ship pipeline system. For example, the temperature of the oil flow can be increased, or the filter system can be set to a primary filter, a secondary filter, or a tertiary filter for adjustment.

[0052] The aforementioned ship piping system wash-through method further includes evaluating the wash-through cycle of the ship piping system, and comparing the evaluated wash-through cycle with the target cycle. In the wash-through system of the ship piping system, according to the law of conservation of mass of pollutant particles in the ship piping system, the mass of pollutant particles can be described by the following differential equation:

[0053] (q i ×c i ×dt-q o ×c o ×dt)=V×dc (1)

[0054] q i =q o (2)

[0055]

[0056] Where V represents the oil tank capacity in the ship’s pipeline system, m 3 ;c i Indicates the pollutant concentration in the ship pipeline system downstream of the filter (return oil), pieces / 100mL; c o It represents the pollutant concentration in the ship pipeline system upstream of the filter (dirty oil), pieces / 100mL; β represents the filtration ratio of the filter installed in the ship pipeline system; q i Indicates the oil flow out of the filter, m 3 / s;q o Indicates the oil flow rate into the filter, m 3 / s; t represents the series washing cycle.

[0057] The first term on the left side of formula (1) is the number of pollutant particles brought into the fuel tank by the filtered return oil, and the second term is the number of pollutant particles discharged with the flowing oil in the fuel tank. The right side of formula (1) represents the number of pollutant particles in the fuel tank. Based on formulas (1), (2) and (3), we get formula (4):

[0058]

[0059] Among them, c s Indicates the real-time concentration of pollutants in the fuel tank, c 12 represents the initial concentration of pollutants in the fuel tank.

[0060] Based on the half-life equation of oil flow in ship pipeline system, the half-life is the washing cycle required for heavy pollutants in GJB 420B-2006 to decrease by one level. For each decrease in pollutant concentration, the number of pollutant particles decreases by half. Therefore, the washing cycle required for the particle pollution degree in oil flow of ship pipeline system to decrease by n levels can be obtained by simulation calculation using the following formula:

[0061]

[0062] Where n is the number of levels of pollution level reduction of pollutants in the fuel tank. For example, if the pollution level is reduced from level 10 to level 8, n is 2.

[0063] The ship pipeline system includes an oil tank connected in series with the ship pipeline and a filter unit arranged in the ship pipeline. The filter unit can be a single-stage filter or a multi-stage filter. Specifically, the filter unit includes one filter or multiple filters. When the concentration of pollutants in the oil tank before and after each filter is less than or equal to the concentration of pollutants corresponding to the target level, it means that the current ship pipeline system series washing meets the requirements, and the series washing is completed.

[0064] In one embodiment, when the filter unit in the ship piping system of the embodiment of the present application is a single-stage filter, such as Figure 3 As shown, a filter is installed in a branch of the ship pipeline, and the process of washing begins until the concentration of pollutants in the oil tank before the filter is less than or equal to the concentration of pollutants corresponding to the target level is started. The time consumed is recorded as t1, and t1 satisfies formula (7)

[0065]

[0066] The time taken to start the series washing until the concentration of pollutants in the fuel tank after passing through the filter is less than or equal to the concentration of pollutants corresponding to the target level is recorded as t2, and t2 satisfies formula (8):

[0067]

[0068] Among them, c 12represents the initial concentration of pollutants in the tank, and c represents the pollutant concentration corresponding to the target level. In specific use, the time required to reach the target level is first calculated by simulation through formula (7) and formula (8). When t1 and t2 are both less than or equal to the target cycle, the evaluation series washing cycle is less than or equal to the target cycle, indicating that the series washing cycle of the current ship pipeline system is suitable for the current project progress.

[0069] In another embodiment, the filter unit in the ship piping system of the embodiment of the present application is a secondary filter, such as Figure 4 As shown, it includes a first filter and a second filter connected in series in the ship pipeline. The time consumed from the start of the series washing until the concentration of pollutants in the oil tank before passing through the first filter is less than or equal to the concentration of pollutants corresponding to the target level is recorded as t3, and t3 satisfies formula (9)

[0070]

[0071] The time taken to start the series washing until the concentration of pollutants in the fuel tank after the first filter and before the second filter is less than or equal to the concentration of pollutants corresponding to the target level is t4, and t4 satisfies formula (10):

[0072]

[0073] The time taken to start the series washing until the concentration in the fuel tank after passing through the second filter is less than or equal to the pollutant concentration corresponding to the target level is t5, and t5 satisfies formula (11):

[0074]

[0075] Wherein, c represents the pollutant concentration corresponding to the target level, c 12 represents the initial concentration of pollutants in the ship piping system, β1 represents the filtration ratio of the first filter, and β2 represents the filtration ratio of the second filter. In specific use, the time required to reach the target level is first calculated by simulation through formulas (9) to (11). When t4 to t6 are all less than or equal to the target cycle, the evaluation series washing cycle is less than or equal to the target cycle, indicating that the series washing cycle of the current ship piping system is suitable for the current project progress.

[0076] The ship piping system of the present application may also be provided with three or more filter units, according to Figure 3 or Figure 4 The arrangement of filters and online measuring devices can be increased or decreased to achieve multi-stage filtration. When the number of filters is increased, the pollutant concentration half-life equations of formulas (10) and (11) can be used for calculation, and the corresponding filtration ratio can be adjusted accordingly.

[0077] If the evaluated series washing cycle is less than or equal to the target cycle, the ship's pipeline system will be washed according to the currently set parameters. When the evaluated series washing cycle of the ship's pipeline system is greater than the target cycle, if the series washing is directly performed according to the corresponding settings of the evaluated series washing cycle, the time consumed for series washing will be greatly increased, and the construction period will be extended. In order to ensure the progress of the project, the evaluated series washing time can be combined with the current online measurement equipment to monitor the particle contamination data in real time, and the current particle contamination and the required series washing time can be interactively fed back in real time. Corrections can be made based on the required time and target cycle oil temperature, and the accuracy ladder configuration of each level of filter elements can be reasonably planned according to different series washing stages and filter element dirty blockage conditions. For example, the filter unit in the ship's pipeline system can be adjusted and multi-stage filtration can be added to make the evaluated series washing cycle less than or equal to the target cycle.

[0078] like Figure 5 As shown, the second aspect of the present application provides a ship piping system series washing device, which includes a pollutant level judgment module, a series washing cycle evaluation module and an execution module; wherein the pollutant level judgment module is used to obtain the pollutant pollution level in the ship piping system, and if the pollutant pollution level is greater than the target level, the ship piping system is series washed. The aforementioned target level can determine the corresponding level according to the specific usage scenario of the ship piping system. For example, the target level can be set to level 8, level 6 or level 4. If the pollution level of the pollutants in the ship piping system is less than or equal to the target level, it indicates that the oil flow quality of the ship piping system has met the requirements, and the ship piping system ends series washing or does not need series washing. If the pollutant pollution level of a branch of the ship piping system is greater than the target level, it indicates that the ship piping system needs to be series washed.

[0079] The wash cycle assessment module is used to assess the wash cycle of the ship's piping system and compare the assessed wash cycle with the target cycle; the estimated wash cycle is calculated using the following formula:

[0080]

[0081] Wherein, t represents the estimated series washing cycle, n represents the pollution level reduction level of pollutants in the ship piping system, V represents the oil tank capacity in the ship piping system, β represents the filtration ratio of the filter installed in the ship piping system, and q represents the oil flow rate.

[0082] The ship pipeline system includes an oil tank connected in series with the ship pipeline and a filter unit arranged in the ship pipeline, and the filter unit can be a single-stage filter or a multi-stage filter. In one embodiment, when the filter unit in the ship pipeline system of the embodiment of the present application is a single-stage filter, such as Figure 3As shown, a filter is installed in a branch of the ship pipeline, and the process of washing begins until the concentration of pollutants in the oil tank before the filter is less than or equal to the concentration of pollutants corresponding to the target level is started. The time consumed is recorded as t1, and t1 satisfies formula (7)

[0083]

[0084] The time taken to start the series washing until the concentration of pollutants in the fuel tank after passing through the filter is less than or equal to the concentration of pollutants corresponding to the target level is recorded as t2, and t2 satisfies formula (8):

[0085]

[0086] Among them, c 12 represents the initial concentration of pollutants in the fuel tank, and c represents the pollutant concentration corresponding to the target level. When t1 and t2 are both less than or equal to the target cycle, the estimated series washing cycle is less than or equal to the target cycle.

[0087] In another embodiment, the filter unit in the ship piping system of the embodiment of the present application is a secondary filter, such as Figure 4 As shown, it includes a first filter and a second filter connected in series in the ship pipeline. The time consumed from the start of the series washing until the concentration of pollutants in the oil tank before passing through the first filter is less than or equal to the concentration of pollutants corresponding to the target level is recorded as t3, and t3 satisfies formula (9)

[0088]

[0089] The time taken to start the series washing until the concentration of pollutants in the fuel tank after the first filter and before the second filter is less than or equal to the concentration of pollutants corresponding to the target level is t4, and t4 satisfies formula (10):

[0090]

[0091] The time taken to start the series washing until the concentration in the fuel tank after passing through the second filter is less than or equal to the pollutant concentration corresponding to the target level is t5, and t5 satisfies formula (11):

[0092]

[0093] Wherein, c represents the pollutant concentration corresponding to the target level, c 12 represents the initial concentration of pollutants in the ship piping system, β1 represents the filtration ratio of the first filter, and β2 represents the filtration ratio of the second filter. When t3, t4 and t5 are all less than or equal to the target cycle, the evaluation series washing cycle is less than or equal to the target cycle.

[0094] The execution module is used to determine the execution of subsequent steps based on the results of the wash cycle evaluation module. If the estimated wash cycle is less than or equal to the target cycle, the ship's pipeline system is washed according to the currently set parameters. When the evaluated wash cycle of the ship's pipeline system is greater than the target cycle, if the wash cycle is directly performed according to the settings corresponding to the evaluated wash cycle, the time spent on the wash cycle will be greatly increased, and the construction period will be extended. In order to ensure the progress of the project, the filter unit in the ship's pipeline system can be adjusted, such as adding multi-stage filtration, so that the wash cycle is less than or equal to the target cycle.

[0095] It should be understood that the specific process of each module executing the above corresponding steps has been described in detail in the above method embodiment, and for the sake of brevity, it will not be repeated here.

[0096] It should also be understood that the division of modules in the embodiments of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation. In addition, each functional module in each embodiment of the present application may be integrated into a processor, or may exist physically separately, or two or more modules may be integrated into one module. The above-mentioned integrated modules may be implemented in the form of hardware or in the form of software functional modules.

As for the aforementioned computer-readable storage medium, those skilled in the art can understand that the implementation example of the functions of the aforementioned system and each unit can be completed by hardware related to the computer program.
