Detailed Description of the Embodiment

[0031] In order to enable those skilled in the art to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the drawings and specific embodiments.

[0032] It should be specifically noted that: in this application, the term "several" refers to an indefinite number of multiple, usually more than two; and when "several" is used to represent the quantity of several components, it does not represent the mutual relationship in terms of quantity among these components.

[0033] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a communication connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meaning of the above terms in this application can be understood according to specific situations.

[0034] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the combined layout system of blast furnace circulating water cooling and tapping yard dust removal provided by the embodiments of this application.

[0035] In the embodiment provided by this application, the combined layout system of blast furnace circulating water cooling and tapping yard dust removal includes a blast furnace circulating water pump station 1 and a tapping yard dust removal system 2. The blast furnace circulating water pump station 1 includes a pump house 11, and the tapping yard dust removal system 2 includes a dust removal pipeline 21 and a dust collector 22 which are connected to each other. At least part of the dust removal pipeline 21 and at least part of the dust collector 22 are arranged in the pump house 11.

[0036] It is not difficult to understand that the blast furnace circulating water pump station 1 can supply water to the blast furnace ironmaking plant in a circulating manner. The water pumps for water supply and return can be arranged inside the pump house 11. The dust removal pipeline 21 of the tapping yard dust removal system 2 can correspond to the flue gas outlet of the blast furnace, so as to introduce the flue gas at the flue gas outlet into the dust collector 22 for dust removal.

[0037] In the related art, the separate layout of the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2 results in a relatively scattered layout structure, which not only makes the floor area larger, the overall engineering quantity of the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2 larger, and the investment cost higher, but also makes the distance between the blast furnace body and the tapping yard and the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2 farther. The lengths of the relevant pipelines, such as the water supply pipeline and the return water pipeline of the blast furnace circulating water pump station 1 and the dust removal pipeline 21 of the tapping yard dust removal system 2, are longer. As a result, the loss of force for water supply, return water and flue gas flow is larger, and the energy consumption, such as electric energy, required for the operation of equipment such as water circulation pumps and dust removal fans is higher. Correspondingly, the operation cost is higher.

[0038] Compared with the related art, in the blast furnace circulating water cooling and tapping yard dust removal combined layout system provided by the above embodiments of the present application, since at least part of the dust removal pipeline 21 and at least part of the dust collector 22 are arranged in the pump house 11, the combined layout of the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2 is realized, which can make the layout structure of the two relatively compact. This is not only beneficial to reducing the floor area, thereby reducing the overall engineering quantity of the two, lowering the investment cost, and efficiently utilizing land resources, but also can arrange the system near the blast furnace body and the tapping yard, which is beneficial to shortening the distances between the blast furnace body and the tapping yard and the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2. Correspondingly, the lengths of the water supply pipeline and the return water pipeline of the blast furnace circulating water pump station 1 and the dust removal pipeline 21 of the tapping yard dust removal system 2 can be shortened, so as to reduce the losses of the forces required for water supply, return water, and flue gas flow, thereby reducing the energy consumption such as electric energy required for water circulation and dust removal, and reducing the operating cost.

[0039] It should be noted that, as shown in the above embodiments, at least part of the dust removal pipeline 21 and at least part of the dust collector 22 can both be arranged in the pump house 11, or only at least part of the dust removal pipeline 21 can be arranged in the pump house 11, or only at least part of the dust collector 22 can be arranged in the pump house 11, and there is no specific limitation.

[0040] In the embodiment provided by the present application, the blast furnace circulating water pump station 1 further includes an electrical control room 12; the electrical equipment and control equipment of the blast furnace circulating water pump station 1 are arranged in the electrical control room 12, and the electrical equipment and control equipment of the tapping yard dust removal system 2 are arranged in the electrical control room 12.

[0041] It is not difficult to understand that the electrical equipment includes devices such as generators, transformers, motors, power lines, circuit breakers, and distribution cabinets in the power system, which are used to ensure the normal operation of the power system in the blast furnace ironmaking plant, specifically for the transmission and distribution of electric power, the conversion and control of electric energy, and the protection of the power system. The control equipment such as controllers, consoles, monitors, etc. can be used to control the operation of the corresponding equipment or systems in the blast furnace ironmaking plant.

[0042] Compared with the prior art where the blast furnace circulating water pump station and the tapping yard dust removal system each independently set up an electrical control room to independently store electrical equipment and independently control and manage the system, resulting in a relatively scattered layout of power supply cables, a relatively long cable length, and relatively scattered control and management of the system, with a relatively large difficulty in control and management and a relatively large number of production management personnel required, thus making the system operation cost relatively high. The blast furnace circulating water cooling and tapping yard dust removal combined layout system provided in the above embodiments of the present application can make the layout structures of the two more compact by arranging the electrical equipment and control equipment of the blast furnace circulating water pump station 1 and the electrical equipment and control equipment of the tapping yard dust removal system 2 in the electrical control room 12, that is, by jointly building the electrical control rooms of the blast furnace circulating water pump station 1 and the tapping yard dust removal system 2, which can reduce the cable length, can also centrally control and manage, reduce the difficulty of control and management, and reduce the production management personnel, and accordingly can reduce the operation cost of the system.

[0043] As Figure 1 shown, in the embodiment of the present application, at least part of the dust removal pipeline 21 is arranged in the electrical control room 12. In this way, the electrical control room 12 can be used for the layout of the dust removal pipeline 21 to make the layout structure of the system more compact.

[0044] It should be noted that it is possible that only at least part of the dust removal pipeline 21 is arranged in the electrical control room 12 as shown in the above embodiment, or only at least part of the dust collector 22 is arranged in the electrical control room 12, or at least part of the dust removal pipeline 21 and at least part of the dust collector 22 are both arranged in the electrical control room 12, and there is no specific limitation.

[0045] In actual setting, the positions of the dust removal pipeline 21 and the dust collector 22 on the pump house 11 and the electrical control room 12 are not limited.

[0046] In the embodiment provided by the present application, as Figure 1 shown, at least part of the dust removal pipeline 21 and at least part of the dust collector 22 are arranged outside the roof of the pump house 11, and at least part of the dust removal pipeline 21 is arranged outside the roof of the electrical control room 12. In this way, the space in the height direction of the pump house 11 and the electrical control room 12 can be fully utilized to make the layout structure of the system more compact, which is beneficial to further reducing the floor area and reducing the system energy consumption.

[0047] Please combine Figure 1 to understand that in the embodiment of the present application, the dust removal pipeline 21 includes a pre-dust removal pipeline 211 and a post-dust removal pipeline 212. The pre-dust removal pipeline 211 is connected to the air inlet of the dust collector 22, and the post-dust removal pipeline 212 is connected to the air outlet of the dust collector 22; the electrical control room 12 is located on one side of the pump house 11, specifically located at Figure 1On the left side of the middle pump house 11, the pre-dust removal pipeline 211 extends from the roof of the electrical control room 12 to the roof of the pump house 11, and the dust collector 22 and part of the post-dust removal pipeline 212 are arranged on the roof of the pump house 11. In this way, the pre-dust removal pipeline 211 and part of the post-dust removal pipeline 212 can extend along the direction from the electrical control room 12 to the pump house 11, so as to make further full use of the space between the electrical control room 12 and the pump house 11 in the height direction.

[0048] In the embodiment provided by the present application, the tapping yard dust removal system 2 further includes a dust removal fan 23 and a dust removal exhaust chimney 24; the dust collector 22, the dust removal fan 23 and the dust removal exhaust chimney 24 are connected in sequence, and the dust removal fan 23 and the dust removal exhaust chimney 24 are arranged on the ground on one side of the pump house 11.

[0049] It is not difficult to understand that the dust removal fan 23 may include a fan body and a motor connected to each other, and the motor is used to drive the fan body to work. During the operation of the two, vibration is likely to occur. In the embodiment of the present application, the dust removal fan 23 and the dust removal exhaust chimney 24 are arranged on the ground on one side of the pump house 11. For example, they can be set nearby Figure 1 on the right side or the right rear side of the middle pump house 11, which can not only make the layout structure of the system more compact, but also reduce the influence of the vibration generated by the operation of the fan body and the motor on the operation of the blast furnace circulating water pump station 1.

[0050] In the embodiment provided by the present application, the tapping yard dust removal system 2 further includes a centralized ash bin 25; the centralized ash bin 25 is used to centrally store the dust intercepted by the dust collector 22, and the centralized ash bin 25 is arranged on the ground on one side of the pump house 11. Specifically, the centralized ash bin 25 can be set nearby Figure 1 on the ground on the right side or the rear side of the middle pump house 11. In this way, not only can the layout structure of the system be made more compact, but also when there is a large amount of stored ash, the weight of the centralized ash bin 25 is relatively heavy. Arranging it on the ground will not increase the force borne by the roof like arranging it on the roof of the pump house 11, and it is also more convenient to handle the stored dust.

[0051] Please refer to Figure 1It is understood that before dust removal, the duct 211 may include several dust removal branch ducts 2111 and a dust removal main duct 2112. The dust removal duct 21 may further include an exhaust duct 26. Specifically, the intake ports of several dust removal branch ducts 2111 may correspond to the respective tapping ports of the blast furnace tapping yard. The outlet ports of several dust removal branch ducts 2111 may be connected to the intake port of the dust removal main duct 2112. The outlet port of the dust removal main duct 2112 may be connected to the intake port of the dust collector 22. The outlet port of the dust collector 22 may be connected to the intake port of the duct 212 after dust removal. The outlet port of the duct 212 after dust removal is connected to the intake port of the dust removal fan 23. The outlet port of the dust removal fan 23 is connected to the intake port of the exhaust duct 26. The outlet port of the exhaust duct 26 is connected to the intake port of the dust removal emission chimney 24. During use, the flue gas from each tapping port is respectively introduced into each dust removal branch duct 2111 and aggregated into the dust removal main duct 2112, and then enters the dust collector 22 for dust removal. The dust in the flue gas is intercepted inside the dust collector 22. The dust collector 22 may be a pulse jet bag filter. The flue gas after dust removal inside it is sucked into the dust removal fan 23 through the duct 212 after dust removal, and is discharged into the dust removal emission chimney 24 by the dust removal fan 23 through the exhaust duct 26, and finally discharged from the system by the dust removal emission chimney 24. After the dust collector 22 operates for a period of time, the dust inside it can be discharged into the centralized ash bin 25 for centralized storage.

[0052] Among them, several dust removal branch ducts 2111 may be arranged starting from the tapping port position of the tapping yard, extending all the way to the roof of the electrical control room 12, and extending from left to right along the roof of the electrical control room 12 to the left side of the pump house 11. The dust removal main duct 2112 may extend from left to right along the roof of the pump house 11 from the outlet port position of the dust removal branch ducts 2111. The dust collector 22 may be arranged in the middle of the roof of the pump house 11 with the intake port on the left and the outlet port on the right. The duct 212 after dust removal may extend from the outlet port position of the dust collector 22 along the roof of the pump house 11 first from left to right and then downward. In this way, the layout structure of the tapping yard dust removal system 2 on the pump house 11 is more compact.

[0053] When specifically setting, the installation method of the dust removal duct 21 and the dust collector 22 on the roofs of the electrical control room 12 and the pump house 11 is not limited.

[0054] In the embodiment of the present application, first brackets (not shown in the figure) are provided on the roofs of both the electrical control room 12 and the pump house 11. The dust removal duct 21 is arranged on the corresponding first brackets. Second brackets are provided on the roof of the pump house 11, and the dust collector 22 is arranged on the second brackets. In this way, the stable installation of the dust removal duct 21 and the dust collector 22 in the blast furnace circulating water pump station 1 can be achieved.

[0055] Please refer to Figure 2 , Figure 2Schematic diagram of the internal structure of the blast furnace circulating water pump station in the combined layout system of blast furnace circulating water cooling and cast house dust removal provided by this application.

[0056] In actual setting, the layout form of the blast furnace circulating water pump station 1 is not limited.

[0057] In the embodiment provided by this application, the blast furnace circulating water pump station 1 further includes a water tank group 13 and a cooling device 14; the water tank group 13 is arranged on one side of the pump house 11, and specifically on the front side of the pump house 11 in Figure 1 Among them. The water tank group 13 includes several water tanks, and at least one water tank is connected to the cooling device 14 through a circulating water pipeline, and at least part of the cooling device 14 is arranged outside the top cover of at least one water tank.

[0058] Compared with the prior art, in which the cooling device and the water tank of the blast furnace circulating water pump station are separately and independently arranged and a separate circulating water pipe gallery is set, resulting in a relatively scattered layout structure, a large floor area, a high investment cost of the system, and a long length of the water supply pipeline and the water return pipeline connecting the cooling device and the water tank, resulting in a high energy loss during the water supply and water return processes and a high consumption of electric energy required for the water cycle, making the operation cost of the system high. In the combined layout system of blast furnace circulating water cooling and cast house dust removal provided by the above embodiment of this application, the cooling device 14 is arranged near the top cover of the water tank, which can make full use of the space in the height direction of the water tank, making the layout structure of the blast furnace circulating water pump station 1 relatively compact, reducing the floor area of the blast furnace circulating water pump station 1, shortening the length of the water supply pipeline and the water return pipeline, and saving the investment cost and the operation cost.

[0059] In the embodiment of this application, the cooling device 14 includes an evaporative air cooler 141, and the water tank group 13 includes a soft water tank 131 and a spray water tank 132; the evaporative air cooler 141 is used to provide cooled soft water for the blast furnace ironmaking plant and to cool the soft water return water of the blast furnace ironmaking plant. The soft water tank 131 is connected to the soft water make-up port of the evaporative air cooler 141, and the spray water tank 132 is connected to the spray water inlet of the evaporative air cooler 141; at least part of the evaporative air cooler 141 is arranged outside the top cover of the soft water tank 131 and outside the top cover of the spray water tank 132.

[0060] It can be understood that several water pumps can be arranged inside the pump house 11. For example, a soft water make-up pump, a soft water spray pump, and a soft water circulation pump can be arranged. The evaporative air cooler 141 can be provided with a heat exchanger, a fan, and a spray assembly. The soft water outlet of the heat exchanger can be connected to the soft water inlet of the soft water using equipment of the blast furnace, such as the water jacket, through a soft water supply pipeline. The soft water inlet of the heat exchanger can be connected to the soft water outlet of the water jacket through a soft water return pipeline. The soft water make-up port of the heat exchanger can be connected to the soft water tank 131 through a soft water make-up pipeline. The spray water inlet of the spray assembly can be connected to the spray water tank 132 through a spray water supply pipeline. The spray water outlet of the evaporative air cooler 141 can be connected to the spray water tank 132 through a spray water return pipeline. The soft water circulation pump can be arranged in the soft water supply pipeline and the soft water return pipeline. The soft water make-up pump can be arranged in the soft water make-up pipeline. The soft water spray pump can be arranged in the spray water supply pipeline. During use, the soft water circulation pump can be used to supply the cooled soft water inside the heat exchanger to the water jacket to cool the blast furnace body, and the used soft water can be sent back to the heat exchanger. The air cooling generated by the fan can be used to cool the soft water inside the heat exchanger. When the air cooling generated by the fan is not sufficient to cool the soft water inside the heat exchanger, the soft water spray pump can be used to supply the spray water inside the spray water tank 132 to the spray assembly to use the spray assembly to spray and generate water cooling to cool the soft water inside the heat exchanger. The sprayed water can be concentrated in the spray water tank at the lower part of the evaporative air cooler 141 and can flow back to the spray water tank 132 through the spray water return pipeline; when the soft water inside the heat exchanger is insufficient, the soft water in the soft water tank 131 can be supplemented to the heat exchanger through the soft water make-up pump.

[0061] In the above embodiment of the present application, the evaporative air cooler 141 is arranged near the top covers of the soft water tank 131 and the spray water tank 132, and the relevant circulating water pipelines can be partially arranged on the top covers of the soft water tank 131 and the spray water tank 132, which can make full use of the space above the soft water tank 131 and the spray water tank 132, make the layout structure of the system more compact, and is beneficial to further shortening the lengths of the above-mentioned soft water supply pipeline, soft water return pipeline, soft water make-up pipeline, spray water supply pipeline, and spray water return pipeline, and reducing the energy consumption generated by soft water circulation, supplementation, and spray water supply.

[0062] In the embodiment provided by the present application, the cooling device 14 further includes a cooling tower 142, and the water tank group 13 includes a clean circulating water tank 133; the clean circulating water tank 133 is used to provide cooled clean circulating water for the blast furnace ironmaking plant, the cooling tower 142 is used to cool the clean circulating water return water of the blast furnace ironmaking plant, and the clean circulating water outlet of the cooling tower 142 is connected to the clean circulating water tank 133; at least part of the cooling tower 142 is arranged outside the top cover of the clean circulating water tank 133.

[0063] It is not difficult to understand that a blast furnace ironmaking plant has net circulating water using equipment. For example, in a blast furnace blower station, a hydraulic station, an air compressor, a fan, etc., a net circulating water pump can be installed inside the pump house 11. The net circulating water tank 133 can be connected to the net circulating water inlets of the net circulating water using equipment through a net circulating water supply pipeline. The net circulating water outlets of the net circulating water using equipment can be connected to the net circulating water inlets of the cooling tower 142 through a net circulating water return pipeline. The net circulating water outlet of the cooling tower 142 can be connected to the net circulating water tank 133 through a pipeline after the net circulating water is cooled. The net circulating water pump can be installed in net circulating water pipelines such as the net circulating water supply pipeline and the net circulating water return pipeline. Specifically, the cooled net circulating water inside the net circulating water tank 133 can be supplied to the net circulating water using equipment by using the net circulating water pump, and the net circulating water used by the net circulating water using equipment can be sent to the cooling tower 142 for cooling, and the cooled net circulating water is sent back to the net circulating water tank 133.

[0064] In the above embodiments of the present application, since the cooling tower 142 is disposed near the top cover of the net circulating water tank 133, the related circulating water pipelines can be partially disposed on the top cover of the net circulating water tank 133, which can make full use of the space above the net circulating water tank 133, making the layout structure of the system more compact, and being beneficial to further shortening the lengths of the net circulating water supply pipeline, the net circulating water return pipeline, and the pipeline after the net circulating water is cooled, and reducing the energy consumption generated by the net circulating water circulation.

[0065] It should be noted that in the above embodiments of the present application, part of the evaporative air cooler 141 is disposed on the top covers of the soft water tank 131 and the spray water tank 132, and part of the cooling tower 142 is disposed on the top cover of the net circulating water tank 133. This is only to dispose the cooling device 14 near the top cover of the relevant water tank. Actually, it is not limited to this setting method. For example, part of the evaporative air cooler 141 can also be disposed on the top cover of the net circulating water tank 133, or part of the evaporative air cooler 141 and the cooling tower 142 can be disposed on the top covers of other water tanks.

[0066] As Figure 1 and Figure 2 shown, in the embodiments of the present application, the water tank group 13 further includes a fire fighting water tank 134; the fire fighting water tank 134 is used to provide fire fighting water for the blast furnace ironmaking plant, and at least part of the cooling device 14 is disposed outside the top cover of the fire fighting water tank 134.

[0067] It is not difficult to understand that a fire fighting water supply pump can be installed inside the pump house 11. The fire fighting water tank 134 can be connected to the fire fighting system of the blast furnace ironmaking plant through a fire fighting water supply pipeline to supply fire fighting water for the fire fighting system.
