Description

Technical Field

[0001] This invention relates to the field of industrial control technology, and in particular to a control method, device, electronic equipment and storage medium for a blast furnace taphole dust removal system. Background Technology

[0002] The blast furnace taphole dust removal system is a system that collects and treats the fumes and dust generated during the blast furnace tapping process by drawing them into the dust removal pipeline through a dust collector.

[0003] To avoid dust pollution during blast furnace tapping, steel manufacturing enterprises keep their dust collectors constantly running at high speeds, with hourly extraction volumes reaching up to 1 million cubic meters per second. 3 The above indicates that the hourly ventilation volume still reaches 500,000 m³ during the iron-discharging process. 3 The dust removal motor has a power of 2000 kWh. Currently, the dust removal operation at the taphole mainly relies on manual operation by the furnace front staff. At least 5 minutes before opening the taphole, the furnace front staff will turn on the dust collector in the dust removal system and run it at high speed until the taphole is blocked and no slag or iron flows out. Then, the furnace front staff will manually switch the dust collector to low speed operation.

[0004] The aforementioned method of manually controlling the dust collector cannot adjust its speed according to the tapping status of the blast furnace taphole, resulting in high power consumption, wasted electricity, and increased costs for the blast furnace taphole dust collection system. Summary of the Invention

[0005] This invention provides a control method, device, electronic equipment, and storage medium for a blast furnace taphole dust removal system, in order to solve the problems of high power consumption, wasted electricity, and increased costs in existing dust removal systems that are manually controlled and cannot adjust the speed of the dust collector according to the tapping status of the blast furnace taphole.

[0006] In a first aspect, the present invention provides a control method for a blast furnace taphole dust removal system, applicable to a dust removal system including a No. 1 dust collector, a No. 2 dust collector, a No. 3 dust collector, and a temperature sensor. The air inlet of the No. 1 dust collector is located above the main groove area of ​​the blast furnace taphole. The air inlets of the No. 2 and No. 3 dust collectors are at a first distance from the blast furnace taphole and are respectively located on the left and right sides of the main groove at a second distance from the main groove. The blast furnace taphole dust removal system control method includes:

[0007] Upon receiving the purging signal and the drill rod drive signal, the No. 1 dust collector is controlled to run at the first speed.

[0008] Receive the temperature of each area detected by the temperature sensor;

[0009] The rotation speeds of dust collectors No. 1, No. 2, and No. 3 are controlled according to the temperature of each area.

[0010] Upon receiving a signal indicating that the iron tap is blocked, the No. 1, No. 2, and No. 3 dust collectors are stopped based on the temperature of each area.

[0011] Secondly, the present invention provides a control device for a blast furnace taphole dust removal system, applied to a dust removal system including a No. 1 dust collector, a No. 2 dust collector, a No. 3 dust collector, and a temperature sensor. The air inlet of the No. 1 dust collector is located above the main groove area of ​​the blast furnace taphole. The air inlets of the No. 2 and No. 3 dust collectors are at a first distance from the blast furnace taphole and are respectively located on the left and right sides of the main groove at a second distance from the main groove. The blast furnace taphole dust removal system control device includes:

[0012] The No. 1 dust collector start module is used to control the No. 1 dust collector to run at a first speed when it receives a purging signal and a drill rod drive signal;

[0013] A temperature acquisition module is used to receive the temperature of each area detected by the temperature sensor;

[0014] The dust collector speed control module is used to control the speed of dust collector No. 1, dust collector No. 2 and dust collector No. 3 according to the temperature of each area;

[0015] The dust collector stop operation control module is used to control the No. 1 dust collector, No. 2 dust collector, and No. 3 dust collector to stop operation based on the temperature of each area when a blockage signal is received at the iron tap.

[0016] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0017] At least one processor; and

[0018] A memory communicatively connected to the at least one processor; wherein,

[0019] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the blast furnace taphole dust removal system control method according to the first aspect of the present invention.

[0020] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the blast furnace taphole dust removal system control method described in the first aspect of the present invention.

[0021] The blast furnace taphole dust removal system of this invention is equipped with a temperature sensor. Upon receiving a purging signal and a drill rod drive signal, it controls the No. 1 dust collector to run at a first speed. It receives the temperature of each area detected by the temperature sensor and controls the speeds of the No. 1, No. 2, and No. 3 dust collectors based on the temperature of each area. Upon receiving a taphole blockage signal, it controls the No. 1, No. 2, and No. 3 dust collectors to stop running based on the temperature. This system determines the various stages and states of blast furnace tapping by measuring the temperature of each area detected by the temperature sensor, thereby controlling the No. 1, No. 2, and No. 3 dust collectors to run and stop at different speeds. It can correlate and adjust the various stages and temperatures during the tapping process with the speed of the dust collectors, achieving the goal of reducing dust collector power consumption and saving energy. Furthermore, it eliminates the need for manual control of the dust collectors, improving the level of intelligence.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] Example 1

[0031] Figure 1 This is a flowchart of a control method for a blast furnace taphole dust removal system provided in Embodiment 1 of the present invention. This embodiment is applicable to controlling the dust collector in a blast furnace taphole dust removal system. The method can be executed by a blast furnace taphole dust removal system control device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the control method for the blast furnace taphole dust removal system includes:

[0032] S101. Upon receiving the purging signal and the drill rod drive signal, control the No. 1 dust collector to run at the first speed.

[0033] like Figure 2 The diagram shown is a schematic representation of the distribution of dust collectors in a blast furnace taphole dust removal system according to an embodiment of the present invention. Figure 2 The diagram shows a blast furnace 1, a taphole 11 located on the blast furnace, a main trough 2, a No. 1 dust collector 3, a No. 2 dust collector 4, and a No. 3 dust collector 5. The main trough 2 is located directly below the taphole 11. When the taphole 11 is opened, the molten iron in the taphole flows into the main trough 2. The No. 1 dust collector 3 is located 3 meters above the taphole 11. The No. 2 dust collector 4 and the No. 3 dust collector 5 are located 2 meters to the left and right of the main trough 2, respectively. The center of the No. 2 dust collector 4 and the No. 3 dust collector 5 in the direction of the main trough 2 is level with the landing point of the molten iron flowing out of the taphole 11. The height of the No. 2 dust collector 4 and the No. 3 dust collector 5 can be equal to or unequal to that of the No. 1 dust collector 3.

[0034] in addition, Figure 2The dust collectors 3, 4, and 5 shown are dust collection hoods for dust collectors 3, 4, and 5, respectively. The dust collection hood for dust collector 3 is a rectangle with a length of 4 meters and a width of 2.4 meters. The dust collection hoods for dust collectors 4 and 5 are squares with sides of 2.4 meters. Dust collectors 3, 4, and 5 can operate at a first speed, with a suction volume of 100,000 cubic meters per hour for each dust collector, or at a second speed, with a suction volume of 300,000 cubic meters per hour for each dust collector. The first and second speeds are adjustable. In this embodiment, the second speed is greater than the first speed; relatively speaking, the first speed is a low speed, and the second speed is a high speed.

[0035] In addition, the blast furnace taphole dust removal system in this embodiment is also equipped with a temperature sensor, which can be a thermal imaging temperature sensor. The thermal imaging temperature sensor can collect the temperature of various areas in front of the taphole of the blast furnace. For example, the thermal imaging temperature sensor can cover a space of 2 meters on each side of the main channel, 3 meters high, and the length from the taphole to the skimmer.

[0036] When the blast furnace taphole is not open, it is sealed with taphole clay. When it is necessary to open the taphole, the taphole clay is removed by drilling with a drill rod. When the purging signal and the drill rod drive signal are received, the No. 1 dust collector is first controlled to open and run at the first speed. For example, when the purging signal, the drill rod advance signal and the rotation signal are received, it is determined that the drill rod has started to open the taphole and the molten iron is about to flow into the main channel. Then the No. 1 dust collector can be started and controlled to run at a lower first speed. Starting the No. 1 dust collector at a low speed when drilling the taphole can avoid the waste of electricity by running the No. 1 dust collector at high speed when the molten iron has not flowed out.

[0037] S102, Receive the temperature of each area detected by the temperature sensor.

[0038] Specifically, the temperature sensor detects the temperature of each area in real time and transmits the temperature of each area to the controller. The controller can receive the temperature of each area, which mainly includes the main trench area, the left side area of ​​the main trench, and the right side area of ​​the main trench.

[0039] S103. Control the rotation speed of dust collector No. 1, dust collector No. 2 and dust collector No. 3 according to the temperature of each area.

[0040] In this embodiment, temperature thresholds for each region can be set based on the characteristics of each stage of molten iron flow from the taphole. Different stages of molten iron flow from the taphole can be determined by the temperature of each region and the temperature thresholds. After determining the stages of molten iron flow from the taphole by temperature, the rotation speeds of dust collectors No. 1, No. 2, and No. 3 can be controlled. For example, when the highest temperature in the main channel region is detected to be greater than a preset threshold, it indicates that molten iron from the taphole has entered the main channel region, and the temperature difference between the high-temperature molten iron and the surface and sides of the main channel is large, generating a lot of dust. In this case, dust collectors No. 1, No. 2, and No. 3 can be controlled to operate at high speed. When the lowest temperature in each region is higher than a preset value, and the highest temperature is close to the molten iron temperature, it is determined that the molten iron flowing from the taphole is in a stable state. Dust collector No. 1 can be controlled to maintain high-speed operation. Then, the rotation speeds of dust collectors No. 2 and No. 3 are controlled based on the temperatures on both sides of the main channel. In this embodiment, the rotation speed of each dust collector can be controlled based on the temperature of each region. The specific control strategy can be determined based on the correlation between the stages of molten iron flow and temperature. This embodiment does not limit the specific control strategy.

[0041] S104. Upon receiving a signal indicating that the taphole is blocked, dust collectors No. 1, No. 2, and No. 3 shall be stopped based on the temperature of each area.

[0042] Specifically, upon receiving a signal indicating that the iron tap is blocked, dust collectors No. 1, No. 2, and No. 3 can be controlled to operate at low speeds, and dust collectors No. 1, No. 2, and No. 3 can be controlled to stop operating when the temperature difference between each area and the ambient temperature is within a preset range.

[0043] The blast furnace taphole dust removal system of this invention is equipped with a temperature sensor. Upon receiving a purging signal and a drill rod drive signal, it controls the No. 1 dust collector to run at a first speed. It receives the temperature of each area detected by the temperature sensor and controls the speeds of the No. 1, No. 2, and No. 3 dust collectors based on the temperature of each area. Upon receiving a taphole blockage signal, it controls the No. 1, No. 2, and No. 3 dust collectors to stop running based on the temperature. This system determines the various stages and states of blast furnace tapping by measuring the temperature of each area detected by the temperature sensor, thereby controlling the No. 1, No. 2, and No. 3 dust collectors to run and stop at different speeds. It can correlate and adjust the various stages and temperatures during the tapping process with the speed of the dust collectors, achieving the goal of reducing dust collector power consumption and saving energy. Furthermore, it eliminates the need for manual control of the dust collectors, improving the level of intelligence.

[0044] Example 2

[0045] Figure 3This is a flowchart of a blast furnace taphole dust removal system control method provided in Embodiment 2 of the present invention. This embodiment of the present invention is an optimization based on Embodiment 1 described above, such as... Figure 3 As shown, the control method for the blast furnace taphole dust removal system includes:

[0046] S301. Upon receiving the purging signal and the drill rod drive signal, control the No. 1 dust collector to run at the first speed.

[0047] In this embodiment, the taphole needs to be drilled through the taphole mud by a drill rod. The drill rod drive signal can include a drill rod advance signal and a drill rod rotation signal. When the purging signal, the drill rod advance signal and the drill rod rotation signal are received at the same time, it is determined that the taphole is about to open. The No. 1 dust collector can be started and controlled to run at a lower first speed.

[0048] S302, Receives the temperature of each area detected by the temperature sensor.

[0049] Specifically, the temperature sensor detects the temperature of each area in real time and transmits the temperature of each area to the controller. The controller can receive the temperature of each area, which mainly includes the main trench area, the left side area of ​​the main trench, and the right side area of ​​the main trench.

[0050] S303. When the temperature in the main ditch area is higher than the first temperature, control dust collector No. 1, dust collector No. 2 and dust collector No. 3 to run at the second speed, which is higher than the first speed.

[0051] For example, when the drill rod breaks through the taphole mud, the molten iron flowing out of the taphole enters the main channel, and the temperature in the main channel area rises instantly. When the highest temperature in the main channel area is detected to be greater than the first temperature of 1400℃, it indicates that molten iron has flowed into the main channel. The temperature difference between the high-temperature molten iron and the surface of the main channel and both sides of the main channel is large, generating a large amount of smoke and dust. The No. 1 dust collector, No. 2 dust collector, and No. 3 dust collector can be controlled to run at the second speed (high speed). The large amount of smoke and dust generated in the initial stage of molten iron flow is removed by the No. 1 dust collector, No. 2 dust collector, and No. 3 dust collector running at high speed, thus preventing the smoke and dust from leaking into the environment and causing pollution.

[0052] S304. When the lowest temperature is greater than the second temperature and the highest temperature is greater than the third temperature, control the No. 1 dust collector to run at the second speed.

[0053] When the lowest temperature in each area is more than 100°C higher than the second temperature, and the highest temperature is greater than the third temperature (molten iron temperature, approximately 1500°C ± 50°C), it is determined that the molten iron flowing from the taphole is in a stable stage. The No. 1 dust collector can be controlled to continue operating at the second speed (high speed) and execute S305-S306.

[0054] S305. Determine the temperature of the left and right sides of the main ditch.

[0055] Specifically, the temperature of the left and right sides of the main channel can be detected by thermal imaging temperature sensors and sent to the controller, which can receive the temperature of the left and right sides of the main channel.

[0056] S306. Control the rotation speed of dust collectors No. 2 and No. 3 according to the temperature of the left and right sides of the main ditch.

[0057] In one embodiment, such as Figure 2 As shown, dust collector 4 is located on the left side of main ditch 2, and dust collector 5 is located on the right side of main ditch 2. When the minimum temperature in both the left and right sides of main ditch is greater than the second temperature, the temperature difference between the left and right sides of main ditch is calculated. When the difference is greater than the first threshold, it is determined whether the temperature in the left side of main ditch is less than the temperature in the right side of main ditch. If so, dust collector 4 is controlled to run at the first speed. If not, dust collector 5 is controlled to run at the first speed.

[0058] For example, when the temperature in the left side of the main ditch is greater than the temperature in the right side of the main ditch and the difference is greater than the first threshold of 50°C, and the minimum temperature in both the left and right sides of the main ditch is greater than the second temperature of 100°C, the No. 3 dust collector located on the right side of the main ditch operates at the first speed (low speed), while the No. 2 dust collector located on the left side of the main ditch continues to operate at the second speed (high speed). Conversely, when the temperature in the right side of the main ditch is greater than the temperature in the left side of the main ditch and the difference is greater than the first threshold of 50°C, and the minimum temperature in both the left and right sides of the main ditch is greater than the second temperature of 100°C, the No. 3 dust collector located on the right side of the main ditch continues to operate at the second speed (high speed). The No. 2 dust collector located on the left side of the main ditch operates at the first speed (low speed). As the suction volume of the No. 2 and No. 3 dust collectors on both sides of the main ditch changes, the temperature on both sides of the main ditch also changes. According to the temperature change, the No. 2 and No. 3 dust collectors on both sides of the main ditch are used alternately at high speed and low speed. This realizes the control of the speed of each dust collector according to the temperature of different areas. This ensures that there is enough suction volume to remove smoke and dust, reduces the overall power consumption of the dust removal system, saves electricity, and avoids the problem of drawing in a large amount of cold air when all dust collectors are running at high speed, which would cause the heat of the molten iron to be absorbed, resulting in excessive heat loss of the molten iron and a decrease in the fluidity of the molten iron.

[0059] S307. When the detected decrease in the highest temperature within a preset time period is greater than or equal to the second threshold, control the No. 1 dust collector, the No. 2 dust collector, and the No. 3 dust collector to run at the second speed.

[0060] Specifically, as molten iron flows out of the taphole, hot air from inside the blast furnace overflows from the taphole along with the molten iron. Since the temperature of the hot air inside the blast furnace is at least 200°C lower than the temperature of the molten iron, when the thermal imaging temperature sensor detects that the highest temperature drops by at least 50°C above the second threshold, the amount of dust increases due to the sudden change in the highest temperature. This allows the No. 1, No. 2, and No. 3 dust collectors to be controlled to operate at the second speed to remove the dust.

[0061] In another embodiment, when the temperature sensor detects that the increase in the minimum temperature within a preset time period is greater than the fourth threshold, the No. 1 dust collector, the No. 2 dust collector, and the No. 3 dust collector are controlled to operate at the second speed. For example, during the stable tapping of molten iron from the taphole, if the thermal imaging temperature sensor detects that the minimum temperature instantly rises above the fourth threshold by more than 30°C at any time, it is determined that molten iron is splashing from the taphole, causing the minimum temperature to rise instantly within a preset time period of 1-2 seconds. The splashed molten iron is sprayed into the main trench area, and the temperature difference between the splashed molten iron and the location it is sprayed into is too large, resulting in an increase in the amount of smoke and dust. The No. 1 dust collector, the No. 2 dust collector, and the No. 3 dust collector can be controlled to operate at the second speed to suck up the smoke and dust at a high speed.

[0062] S308. After receiving the iron tap blockage signal for a preset time, control dust collector No. 1, dust collector No. 2 and dust collector No. 3 to run at the first speed.

[0063] Specifically, when the hydraulic cannon is blocked, it is confirmed that the hydraulic cannon has blocked the iron outlet. After the iron outlet is blocked for a preset time (e.g., 3 minutes), the molten iron stops flowing and the amount of smoke and dust is small or non-existent. The No. 1, No. 2, and No. 3 dust collectors can be controlled to run at a lower initial speed to reduce the overall power consumption of the dust removal system and save energy.

[0064] S309. When the difference between the lowest temperature detected by the temperature sensor and the ambient temperature is less than the third threshold, control dust collector No. 1, dust collector No. 2 and dust collector No. 3 to stop operating.

[0065] After the iron chute is sealed, as dust collectors No. 1, No. 2, and No. 3 operate at low speeds (first rotation speed) to draw in cold air, a temperature drop is detected in the main trench area. The lowest detected temperature deviates from the atmospheric temperature by less than 10°C from the third threshold, confirming that there is basically no smoke or dust generated. Therefore, dust collectors No. 1, No. 2, and No. 3 can be stopped to avoid wasting energy by running them when there is no smoke or dust.

[0066] The blast furnace taphole dust removal system of this invention is equipped with a temperature sensor. Upon receiving a purging signal and a drill rod drive signal, it controls the No. 1 dust collector to run at a first speed. It receives the temperature of each area detected by the temperature sensor and controls the speeds of the No. 1, No. 2, and No. 3 dust collectors based on the temperature of each area. Upon receiving a taphole blockage signal, it controls the No. 1, No. 2, and No. 3 dust collectors to stop running based on the temperature. This system determines the various stages and states of blast furnace tapping by measuring the temperature of each area detected by the temperature sensor, thereby controlling the No. 1, No. 2, and No. 3 dust collectors to run and stop at different speeds. It can correlate and adjust the various stages and temperatures during the tapping process with the speed of the dust collectors, achieving the goal of reducing dust collector power consumption and saving energy. Furthermore, it eliminates the need for manual control of the dust collectors, improving the level of intelligence.
