Description

Technical Field

[0001] This invention relates to the field of ironmaking, and more particularly to a method, apparatus, equipment, and medium for determining pump pressure. Background Technology

[0002] In blast furnace ironmaking, a closed-loop soft water cooling system is typically used to cool the components within the blast furnace. The heat exchange medium in this system is pressurized by a pressure pump and enters the various coolers within the blast furnace, where it exchanges heat with the components to be cooled, thus achieving the cooling effect. The resistance loss in the closed-loop soft water cooling system affects the head of the pressure pump.

[0003] Because of the large number of components to be cooled inside the blast furnace and the complex piping of the closed-loop soft water cooling system, it is difficult to accurately determine the operating pressure of the pressure pump. This leads to imbalances in the water flow regulation of the cooling system, insufficient localized cooling intensity of the cooler, and damage to the cooling water pipes. Therefore, accurately determining the operating pressure of the pump is an urgent problem to be solved. Summary of the Invention

[0047] This application provides a method for determining pump pressure, which solves the technical problem in the prior art that it is difficult to accurately determine the working pressure of a pump.

[0048] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0049] A method for determining pump pressure includes: determining a first position distribution of each cooling module in a cooling system in a first direction based on the circulation path of the cooling medium in the cooling system; each cooling module is an abstraction of each cooling component in the cooling system; adjusting the relative positional relationship of each cooling module in the first position distribution in a second direction based on the resistance value of each cooling module in the cooling system to obtain a second position distribution, wherein the first direction is perpendicular to the second direction; determining a target cooling module from the cooling modules containing coolers in the cooling system based on the series and parallel connection relationship of the cooling modules containing coolers in the cooling system; determining the connection relationship of the circulation path of the cooling medium corresponding to the target cooling module in the second position distribution as the target path; and determining the working pressure of the pump based on the elevation of the target cooling module and the total resistance corresponding to the target path.

[0050] This application determines the first position distribution of each cooling module in a first direction by the circulation path of the cooling medium in the cooling system. Based on the first position distribution of each cooling module and the resistance value of each cooling module, the second position distribution can be obtained. After determining the second position distribution, the target cooling module is determined according to the series and parallel relationship of the cooling modules containing the cooler. The target path is determined according to the target cooling module and the second position distribution. Based on the total resistance value of the target path and the elevation of the target cooling module, the working pressure of the pump can be accurately determined, thereby ensuring that the working pressure provided by the pump can meet the pressure required by the cooling system.

[0051] After determining the working pressure of the pump, the working pressure of the cooler most prone to insufficient cooling intensity in the cooling system can also be determined based on the working pressure of the pump. The working pressure of this cooler is then compared with the preset working pressure threshold to determine whether the cooling intensity of each cooler in the cooling system meets the preset working pressure threshold.

[0052] This application also adjusts the resistance values ​​of other cooling modules connected in parallel with the target cooling module so that the resistance value of the target cooling module and the resistance value of each other cooling module meet a preset relationship. This makes the resistance values ​​of each path in the cooling system similar, reducing the probability of safety accidents caused by excessive differences in resistance values ​​between different paths.

[0053] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0054] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0055] This application provides, as follows: Figure 1 The method for determining pump pressure shown includes steps S11-S15.

[0056] Step S11: Based on the circulation path of the cooling medium in the cooling system, determine the first position distribution of each cooling module in the first direction; each cooling module is an abstraction of each cooling component in the cooling system.

[0057] Step S12: Based on the resistance value of each cooling module in the cooling system, adjust the relative positional relationship of each cooling module in the first position distribution in the second direction to obtain the second position distribution, wherein the first direction is perpendicular to the second direction.

[0058] Step S13: Based on the series and parallel connection relationship of the cooling modules containing coolers in the cooling system, determine the target cooling module from the cooling modules containing coolers.

[0059] Step S14: In the second position distribution, the connection relationship of the circulation path containing the cooling medium corresponding to the target cooling module is determined as the target path.

[0060] Step S15: Determine the pump's operating pressure based on the elevation of the target cooling module and the total resistance corresponding to the target path.

[0061] Regarding step S11, the first position distribution of each cooling module in the cooling system in the first direction is determined according to the circulation path of the cooling medium in the cooling system; each cooling module is obtained by abstracting each cooling component in the cooling system.

[0062] The cooling system can be a closed-loop soft water cooling system or other cooling systems; there are no restrictions here. The cooling medium in the cooling system can be soft water, machine oil, nitrates, etc., and the specific choice can be made according to the actual situation, which will not be elaborated here.

[0063] The circulation path of the cooling medium in a cooling system refers to the flow path of the cooling medium within the cooling system. For example, in a closed-loop soft water cooling system, the cooling medium is soft water. The flow path of the soft water in the above-mentioned closed-loop soft water cooling system is as follows: blast furnace main water pump outlet - blast furnace water supply pipe - first cooler - second cooler - blast furnace return water pipe - expansion tank - heat exchanger - blast furnace main water pump inlet.

[0064] In other words, after the soft water is pressurized by the water pump and flows out from the outlet of the blast furnace main water pump, it passes through the blast furnace water supply pipe, the first cooler, the second cooler, the blast furnace return water pipe, the expansion tank, and the heat exchanger in sequence, before returning to the water pump through the inlet of the blast furnace main water pump.

[0065] Based on the circulation path of the cooling medium in the cooling system, the distribution of each cooling module at its first position in the first direction can be represented by a coordinate system, a table, or other forms; no restriction is placed here. In the following description, a coordinate system will be used.

[0066] It should be noted that each cooling module is an abstraction of the various cooling components in the cooling system. For example, the outlet of the blast furnace main water pump is a cooling component in a certain cooling system, and it is referred to as the cooling module of the outlet of the blast furnace main water pump in the cooling system.

[0067] like Figure 2 In the diagram, the first direction refers to the horizontal axis. The circulation path of the cooling medium in the cooling system is: blast furnace main water pump outlet - blast furnace water supply pipe - first cooler - second cooler - blast furnace return water pipe - expansion tank - heat exchanger - water pump inlet. Based on the order in which the cooling medium flows through each cooling module (cooling component), the first position distribution of each cooling module is determined (i.e., the horizontal coordinate of each cooling module is determined). Figure 2 In the middle, the distance between two adjacent cooling modules on the horizontal axis is 1m.

[0068] It should be noted that when using a coordinate system, the distance between two adjacent cooling modules on the horizontal axis can be equidistant, for example, fixed at 1m, 2m, or 3m. The distance between two adjacent cooling modules on the horizontal axis can also be unequal; for example, the distance between the cooling module at the outlet of the blast furnace main water pump and the cooling module of the blast furnace water supply pipe on the horizontal axis is 2m, and the distance between the cooling module of the blast furnace water supply pipe and the cooling module of the first cooler on the horizontal axis is 5m.

[0069] Regarding step S12, based on the resistance value of each cooling module in the cooling system, the relative positional relationship of each cooling module in the first position distribution in the second direction is adjusted to obtain the second position distribution, wherein the first direction is perpendicular to the second direction.

[0070] In the coordinate system, the first direction is the horizontal axis. The first direction is perpendicular to the second direction, which is the vertical axis.

[0071] After determining the abscissa of each cooling module in the cooling system based on the circulation path of the cooling medium (that is, the first position distribution in the first direction), the relative positional relationship of each cooling module in the second direction is adjusted according to the resistance value of each cooling module and the abscissa of each cooling module to obtain the second positional distribution (that is, the position of each cooling module in the coordinate system).

[0072] The specific process of obtaining the second positional distribution is as follows:

[0073] like Figure 2 As shown, the x-coordinate of each cooling module has been confirmed by the circulation path of the cooling medium in the cooling system. The x-coordinate of the blast furnace main water pump outlet cooling module is 1, the x-coordinate of the blast furnace water supply pipe cooling module is 2, the x-coordinate of the first cooler cooling module is 3, the x-coordinate of the second cooler cooling module is 4, the x-coordinate of the blast furnace return water pipe cooling module is 5, the x-coordinate of the expansion tank cooling module is 6, the x-coordinate of the heat exchanger cooling module is 7, and the x-coordinate of the water pump inlet cooling module is 8.

[0074] The resistance values ​​of each cooling module in the cooling system are shown in Table 1. Based on the horizontal coordinate of each cooling module and its corresponding resistance value, the relative position of each cooling module in the coordinate system can be obtained, as follows: Figure 3 (That is, the second position).

[0075] Table 1

[0076]

[0077] Since the purpose of this application is to accurately determine the working pressure of the water pump, we can first assume in the coordinate system that the vertical coordinate of the cooling module at the outlet of the blast furnace main water pump is P (i.e., the purpose is to solve for P), that is, the coordinate A of the cooling module at the outlet of the blast furnace main water pump is (1, P), and the resistance value of the cooling module at the outlet of the blast furnace main water pump is 1.11 mH2O. Taking the resistance value of the cooling module at the outlet of the blast furnace main water pump as the slope between the cooling module at the outlet of the blast furnace main water pump and the cooling module of the blast furnace water supply pipe, that is, the vertical coordinate of the cooling module of the blast furnace water supply pipe is (2-1)×1.11+P, which means that the coordinate B of the cooling module of the blast furnace water supply pipe is (2, 1.11+P). The relative positional relationship between the cooling module at the outlet of the blast furnace main water pump and the cooling module of the blast furnace water supply pipe in the coordinate system can be determined, that is, it can be determined in the coordinate system. Figure 2 Based on Figure 3 .

[0078] Regarding step S13, the target cooling module is determined from the cooling modules containing coolers based on the series and parallel connection relationship of the cooling modules containing coolers in the cooling system.

[0079] The series and parallel connections between cooling modules containing coolers can be specifically categorized as follows:

[0080]

Scenario 1

[0081] [Scenario 2]: All cooling modules containing coolers in the cooling system are connected in parallel;

[0082]

Scenario 3

[0083] The cooling module containing cooler 1 is designated as cooling module 1, the cooling module containing cooler 2 is designated as cooling module 2, and the cooling module containing cooler 3 is designated as cooling module 3.

[0084]

Scenario 1

[0085] When all cooling modules containing coolers in the cooling system are connected in series, the cooling module with the highest elevation among the cooling modules containing coolers is taken as the target cooling module.

[0086] For example, in a cooling system, cooling module 1, cooling module 2 and cooling module 3 are connected in series, and their corresponding elevations are 1.66m, 2.58m and 3.85m respectively. Cooling module 3 has the highest elevation, so the cooling module containing cooler 3 is taken as the target cooling module.

[0087]

Scenario 2

[0088] When all cooling modules containing coolers in the cooling system are connected in parallel, the cooling module with the largest resistance value among the cooling modules containing coolers is taken as the target cooling module.

[0089] For example, in a cooling system, cooling module 1, cooling module 2 and cooling module 3 are all connected in parallel, and their corresponding resistance values ​​are 2.20mH2O, 1.85mH2O and 1.95mH2O, respectively. Cooling module 1 has the largest resistance value, so cooling module 1 is the target cooling module.

[0090]

Scenario 3

[0091] When the cooling modules containing coolers in the cooling system are connected in both series and parallel, the cooling module with the largest resistance value among the parallel cooling modules containing coolers is selected as the target cooling module.

[0092] For example, cooling module 2 and cooling module 3 are connected in parallel and then connected in series with cooling module 1. The resistance loss value of cooling module 1 is 2.25 mH2O, the resistance loss value of cooling module 2 is 1.87 mH2O, and the resistance loss value of cooling module 3 is 1.55 mH2O. Since cooling modules 2 and 3 are connected in parallel, only the resistance loss values ​​of cooling modules 2 and 3 are compared. Cooling module 2 has a larger resistance loss value, so cooling module 2 is selected as the target cooling module.

[0093] Regarding step S14, in the second position distribution, the connection relationship of the circulation path containing the cooling medium corresponding to the target cooling module is determined as the target path.

[0094] For example, the circulation path of the cooling medium in a certain cooling system is as follows: blast furnace main water pump outlet - blast furnace water supply pipe - first cooler - second cooler - blast furnace return water pipe - expansion tank - heat exchanger - blast furnace main water pump inlet.

[0095] The relative position of each cooling module in the coordinate system has been confirmed according to steps S11-S13. Since the cooling modules containing the cooler are connected in series, the cooling module with the highest elevation among the cooling modules containing the cooler is taken as the target cooling module. Assuming that the cooling module corresponding to the second cooler has the highest elevation, the target cooling module is the cooling module containing the second cooler.

[0096] Based on the connection relationship of the circulation path of the cooling medium, the coordinates of each cooling module in the coordinate system are connected to form curve L1 in the coordinate system, that is, L1 is the target path, such as... Figure 4 As shown.

[0097] Regarding step S15, the working pressure of the pump is determined based on the elevation of the target cooling module and the total resistance corresponding to the target path.

[0098] After determining the target path, the resistance margin can be determined based on the total resistance loss corresponding to the target path.

[0099] The resistance margin is the extra pressure that the water pump can output during operation. The resistance margin is used to ensure that the cooling system does not operate below normal load.

[0100] The pump's operating pressure is determined based on the total resistance loss, resistance loss margin, and elevation of the target cooling module along the target path.

[0101] The total resistance loss corresponding to the target path is the sum of the slopes corresponding to each cooling module.

[0102] For example, Figure 4 In the diagram, the total resistance Q corresponding to the target path L1 is:

[0103] 1.11mH2O + 1.07mH2O + 3.30mH2O + 4.00mH2O + 2.20mH2O + 1.85mH2O + 3.60mH2O + 1.45mH2O = 18.58mH2O. The resistance loss margin is usually 30%-40% of the total resistance loss. Here, we take 30% of the total resistance loss as the resistance loss margin, that is, the resistance loss margin is 18.58mH2O × 30% = 5.574mH2O.

[0104] exist Figure 4 In the middle, the cooling module containing the second cooler is the target cooling module, and the elevation of the cooling module containing the second cooler as the target cooling module is 40m.

[0105] That is, the pump's operating pressure is the sum of the total resistance loss along the target path, the resistance loss margin, and the elevation of the target cooling module, which is:

[0106] 18.58mH2O + 5.574mH2O + 40m = 64.154mH2O, which is approximately 64.154mH2O × 0.0097 = 0.622MPa in standard units.

[0107] After determining the operating pressure of the cooling system pump, the operating pressure of the target cooling module in the cooling system can also be determined. If the operating pressure of the target cooling module is greater than or equal to a preset operating pressure threshold, it indicates that the operating pressure of the target cooling module can meet the local cooling intensity; if the operating pressure of the target cooling module is less than the preset operating pressure threshold, it indicates that the operating pressure of the target cooling module cannot meet the local cooling intensity, which may cause the coolant pipes of the cooler to rupture, thus creating a safety hazard. The specific method for determining the operating pressure of the target cooling module in the cooling system is as follows:

[0108] The working pressure of the target cooling module is determined based on the resistance values ​​of the target cooling module and all preceding cooling modules in the target path, the working pressure of the pump, and the elevation of the target cooling module.

[0109] For example, Figure 4 In the diagram, the target cooling module is the cooling module containing the second cooler. The resistance values ​​of the target cooling module and all the cooling modules before it are as follows: the resistance value of the target cooling module is 4.00 mH2O, the resistance value of the cooling module containing the first cooler is 3.30 mH2O, the resistance value of the blast furnace water supply pipe cooling module is 1.07 mH2O, the resistance value of the blast furnace main water pump outlet is 1.11 mH2O, the elevation of the cooling module containing the second cooler is 40 m, and the working pressure of the pump is 64.154 mH2O.

[0110] The target cooling module's operating pressure is:

[0111] 64.154mH2O - 1.11mH2O - 1.07mH2O - 4.00mH2O - 3.30mH2O - 40m = 13.604mH2O. Converted to standard pressure units, this is approximately 13.604mH2O × 0.0097 = 0.131 MPa.

[0112] After determining the operating pressure of the target cooling module, it can be determined whether the operating pressure of the target cooling module meets the local cooling requirements based on the operating pressure of the target cooling module and the preset operating pressure threshold.

[0113] If the operating pressure of the target cooling module is greater than the preset operating pressure threshold, then the operating pressure of the target cooling module meets the local cooling requirements.

[0114] For example, the target cooling module has an operating pressure of 0.131 MPa and a preset operating pressure threshold of 0.100 MPa. The operating pressure of the cooling module containing the second cooler is greater than the preset operating pressure threshold, which means that the cooling module containing the second cooler meets the local cooling requirements.

[0115] Furthermore, since the total resistance value of the path where the target cooling module is located is the largest, the target cooling module is the cooling module containing the cooler that is most likely to fail to meet the local cooling requirements in the current cooling system. This means that when the cooling modules containing the second cooler can meet the local cooling requirements, the other cooling modules containing coolers can also meet the local cooling requirements.

[0116] More preferably, after determining the operating pressure of the water pump and the target cooling module, if there are parallel cooling modules containing coolers in the current cooling system, the total resistance value of the path determined by the connection relationship of the circulation path of the cooling medium corresponding to the other cooling modules in parallel with the target cooling module can be increased, making it closer to the total resistance value of the target path, thereby improving the safety of the cooling system. The specific method is as follows:

[0117] Based on the difference between the resistance value of the target cooling module and the resistance value of each other cooling module, the resistance adjustment value of each other cooling module is determined so that the resistance value of the target cooling module and the resistance value of each other cooling module meet the preset relationship.

[0118] Among them, other cooling modules refer to cooling modules connected in parallel with the target cooling module. In other words, the resistance value of the cooling modules containing coolers connected in parallel with the target cooling module is adjusted.

[0119] The preset relationship can be a multiple or difference relationship between the resistance value of the target cooling module and the resistance value of each other cooling module.

[0120] For example, the preset relationship is a multiple of 2 or less. This means that when the resistance value of the target cooling module is within 2 times the resistance value of another cooling module, the cooling system is safer and no adjustment to the resistance value of this cooling module is required. However, when the resistance value of the target cooling module is more than 2 times the resistance value of another cooling module, the cooling system is less safe and the resistance value of this cooling module needs to be adjusted.

[0121] The cooling module containing cooler 1 is designated as cooling module 1, the cooling module containing cooler 2 is designated as cooling module 2, and the cooling module containing cooler 3 is designated as cooling module 3.

[0122] Cooling module 2 and cooling module 3 are connected in parallel, and then connected in series with cooling module 1. The resistance loss value of cooling module 1 is 2.25 mH2O, the resistance loss value of cooling module 2 is 3.87 mH2O, and the resistance loss value of cooling module 3 is 1.55 mH2O.

[0123] Since cooling module 2 and cooling module 3 are connected in parallel, and the resistance value of cooling module 2 is greater than that of cooling module 3, cooling module 2 is the target cooling module. The ratio between the resistance value of cooling module 2 and the resistance value of cooling module 3 is approximately: 3.87mH2O ÷ 1.55mH2O = 2.5 > 2, which means that the resistance value of cooling module 3 needs to be increased.

[0124] The minimum range of the resistance value added by cooling module 2 should be a multiple of the resistance value of the target cooling module, and the maximum should not exceed the resistance value of the target cooling module.

[0125] Specifically, the resistance value of the cooling module containing cooler 3 can be adjusted to within the range of 1.935mH2O-3.87mH2O. When the preset relationship is a multiple of 2, 3.87mH2O ÷ 2 = 1.935mH2O. This means that the minimum resistance value of the cooling module containing cooler 3 needs to be adjusted to 1.935mH2O. Since the maximum resistance value of the cooling modules connected in parallel in the cooling system is 3.87mH2O, the maximum resistance value that can be adjusted to is 3.87mH2O.

[0126] By adjusting the resistance values ​​of other cooling modules to make the resistance value of the target cooling module meet a preset relationship with the resistance value of each other cooling module, the resistance values ​​of each path in the cooling system can be made similar, reducing the probability of safety accidents caused by excessive differences in resistance values ​​between different paths.

[0127] The following explanation uses a closed-loop soft water cooling system as an example to illustrate steps S11-S15. To distinguish them from the steps described above, they will be referred to as steps 1-5 thereafter. Table 2 shows the elevation of each cooling module in the closed-loop soft water cooling system and its corresponding resistance value.

[0128] Table 2

[0129]

[0130]

[0131] The circulation path of the cooling medium in a soft water closed-loop system is as follows: Figure 5 As shown, there are 3 loop paths:

[0132] Water pump outlet - hot air valve supply pipe - hot air valve return pipe - expansion tank - heat exchanger - blast furnace medium pressure water pump inlet.

[0133] Water pump outlet - direct blow pipe supply pipe - direct blow pipe - direct blow pipe return pipe - expansion tank - heat exchanger - water pump inlet;

[0134] Water pump outlet - intermediate jacket water supply pipe - intermediate jacket - intermediate jacket return pipe - expansion tank - heat exchanger - water pump inlet;

[0135] The hot air valve, the direct blowing pipe, and the middle sleeve are connected in parallel.

[0136] like Figure 6 As shown, step 1: Construct a coordinate system and determine the abscissa of each cooling module according to the cooling path of the soft water closed circulation system (adjacent cooling systems are arranged with an equal spacing of 1m). That is, in step S11, determine the first position distribution of each cooling module in the first direction.

[0137] Step 2: Based on the resistance values ​​of each cooling module in Table 2, determine the resistance between each cooling module. Figure 5 The relative positional relationships within the [data]. That is, in step S12, the second positional distribution of each cooling module is obtained.

[0138] Step 3: The cooler hot air valve, cooler direct air pipe, and cooler intermediate sleeve are connected in parallel, and the maximum resistance value of the intermediate sleeve is 20mH2O. That is, the cooling module corresponding to the cooler intermediate sleeve is the target cooling module. In other words, in step S13, the target cooling module is determined.

[0139] Step 4: Determine the connection relationship of the circulation path of the cooling medium corresponding to the cooling module of the middle sleeve as the target path, i.e., L2. That is, in step S14, the target path is determined.

[0140] Step 5: Determine the working pressure of the water pump and the working pressure of the intermediate casing. That is, the working pressure of the pump in step S15.

[0141] The total resistance loss corresponding to L2 is:

[0142] 1.11+4.21+20+44.81+1.85+3.60+7.0+1.45=84.03mH2O.

[0143] The operating pressure of the water pump in the soft water closed-loop circulation system is:

[0144] 84.03mH2O + 84.03mH2O × 30% + 13.8m = 123.03mH2O. Converted to standard working pressure, this is approximately: 123.03mH2O × 0.0097 = 1.18MPa.

[0145] The working pressure of the middle layer is:

[0146] 12.03mH2O - 1.11mH2O - 4.21mH2O - 20mH2O - 13.8mH2O = 83.92mH2O, which translates to approximately 83.95mH2O × 0.0097 = 0.81MPa in standard operating pressure. The operating pressure of the middle jacket (0.81MPa) is greater than the pressure threshold of 0.50MPa for the air vent area, therefore, the operating pressure of the middle jacket is sufficient to meet local cooling requirements.

[0147] In summary, this application determines the first position distribution of each cooling module in a first direction by the circulation path of the cooling medium in the cooling system. Based on the first position distribution of each cooling module and the resistance value of each cooling module, the second position distribution can be obtained. After determining the second position distribution, the target cooling module is determined according to the series and parallel relationship of the cooling modules containing the cooler. The target path is determined according to the target cooling module and the second position distribution. Based on the total resistance value of the target path and the elevation of the target cooling module, the working pressure of the pump can be accurately determined, thereby ensuring that the working pressure provided by the pump can meet the pressure required by the cooling system.

[0148] After determining the working pressure of the pump, the working pressure of the cooler most prone to insufficient cooling intensity in the cooling system can also be determined based on the working pressure of the pump. The working pressure of this cooler is then compared with the preset working pressure threshold to determine whether the cooling intensity of each cooler in the cooling system meets the preset working pressure threshold.

[0149] This application also adjusts the resistance values ​​of other cooling modules connected in parallel with the target cooling module so that the resistance value of the target cooling module and the resistance value of each other cooling module meet a preset relationship. This makes the resistance values ​​of each path in the cooling system similar, reducing the probability of safety accidents caused by excessive differences in resistance values ​​between different paths.
