Description

Technical Field

[0001] The present invention belongs to the technical field of metallurgy, and in particular relates to a heat dissipation control method, system, terminal and storage medium for a hot blast stove. Background Art

[0002] The hot blast furnace is a key piece of equipment in blast furnace smelting. It consists of the furnace shell, internal refractory materials, hot air ducts, air ducts, gas ducts, and associated valves. The working principle is that the gas and air duct valves above the hot blast furnace roof are opened, and the hot blast furnace igniter ignites and heats the cast iron lattice bricks inside the regenerator. When the lattice bricks have accumulated heat and reached a certain temperature, the gas and air duct valves above the furnace roof are closed, and the cold air inlet valve is opened to heat the regenerator. The air is then transported through the hot air outlet to the air intake system and into the blast furnace. This provides a continuous 1100°C high-temperature hot air for blast furnace smelting, and multiple hot blast furnaces must operate in coordination to achieve this.

[0003] Due to long-term intermittent operation of hot blast furnaces, especially in the later stages of their lifespan, the refractory materials protecting the furnace shell are prone to cracking due to factors such as thermal expansion and contraction and aging of the refractory materials. When the internal temperature reaches over 1000°C, the hot air passing through the cracks can burn through the furnace shell. The high pressure and high temperature inside the hot blast furnace can cause very serious equipment and safety accidents. Summary of the Invention

[0052] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0054] The heat dissipation control method for a hot blast stove provided in an embodiment of the present invention is executed by a computer device. Accordingly, the heat dissipation control system for a hot blast stove runs in the computer device.

[0055] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject can be a heat dissipation control system for a hot blast stove. According to different requirements, the order of the steps in the flow chart can be changed, and some steps can be omitted.

[0056] like Figure 1 As shown, the method includes:

[0057] Step 110: Divide the high-temperature area shell of the hot blast furnace into multiple heat dissipation areas, and bind the temperature measuring device and the spray heat dissipation device provided in the same heat dissipation area into a heat dissipation group;

[0058] Step 120: Collect detection data from all temperature measuring devices and filter out abnormal detection data that exceeds a preset temperature threshold;

[0059] Step 130, controlling the spray cooling devices in the same group corresponding to the abnormal detection data to enter the spray cooling state;

[0060] Step 140: Close the gas inlet and air inlet of the hot blast stove.

[0061] To facilitate understanding of the present invention, the heat dissipation control method for a hot blast stove provided by the present invention is further described below based on the principle of the heat dissipation control method for a hot blast stove provided by the present invention and in combination with the process of heat dissipation control of the hot blast stove in the embodiment.

[0062] Specifically, the hot blast stove heat dissipation control method includes:

[0063] S1. Divide the high-temperature area shell of the hot blast furnace into multiple heat dissipation areas, and bind the temperature measuring device and the spray heat dissipation device arranged in the same heat dissipation area into a heat dissipation group.

[0064] The furnace shell of the high-temperature area of ​​the hot blast furnace is divided into 6 heat dissipation areas; the identification codes of the temperature measuring device and the spray heat dissipation device corresponding to the same heat dissipation area are bound to the same heat dissipation group, the temperature measuring device includes an infrared thermal imaging temperature measuring device, and the spray heat dissipation device includes a nozzle, a pipe, a solenoid valve, and a water pump. The pipe is connected to the high-temperature area of ​​the hot blast furnace and a ring water supply pipe is set, and the pipe is equipped with multiple solenoid valves.

[0065] Six high-temperature thermal imaging cameras are installed in the high-temperature area to ensure that infrared thermal imaging temperature measurement can reach the high, medium, and low temperature areas of the hot blast furnace, obtaining comprehensive temperature measurements. The thermal imaging cameras continuously measure the temperature in a fan-shaped manner, covering the entire hot blast furnace. This method monitors the average temperature while capturing and recording the highest temperature. Water pipes are laid in the high-temperature area, and automatic water spray valves are installed below the six cameras. If the hot blast furnace shell temperature exceeds 200°C, water is sprayed to cool the area. A computer alarm is triggered, and the PLC is controlled to close the air and gas pipeline valves. To ensure that the blast furnace is not affected, other hot blast furnaces are put into operation simultaneously.

[0066] The spray cooling system consists of a nozzle, pipes, solenoid valves, and a water pump. The nozzle faces the cooling area and is connected to the water pump via a pipe. The water pump is located in a water reservoir and the pipes are equipped with solenoid valves. A portion of the water in the reservoir is reserved to feed the pressure-stabilizing pump. As water flow increases, the water supply pressure drops. The pipe measurement signal is sent to the frequency converter, increasing the inverter output frequency, the motor speed, and the water supply flow of the water pump. When the water pressure reaches the set value, the system pressure is balanced again. To ensure sufficient cooling for the furnace shell, a DN80 water pipe is connected to the high-temperature area of ​​the hot blast furnace and a circular water supply pipe is installed. Six DN80 electric valves are installed in the middle. When the valves are opened, cooling water is radiated throughout the high-temperature, medium-temperature, and low-temperature areas of the hot blast furnace.

[0067] For the temperature measurement device, the temperature from the thermal imager is introduced into the PLC system for temperature warning and automatic control of the DN80 electric valve spray valve. The PLC system uses the M240 series of Schneider's X80 platform to ensure efficient and stable data acquisition and valve control. The software control software uses Schneider's latest Unity Pro control master software, which introduces the temperature measured by the infrared thermal imaging system. When the continuously measured temperature is higher than the set temperature of 200°C (the upper limit temperature can be set on the screen), the control valve in the corresponding area opens to spray and locks the output command (to prevent false stop of spraying). Until the continuously measured temperature is lower than the set temperature of 70°C or higher, the spray valve is closed after a certain delay (which can be set on the screen). While the spray valve is operating, a voice alarm is transmitted to the main control room and the duty room to alert the on-duty personnel.

[0068] S2. Collect detection data from all temperature measuring devices and filter out abnormal detection data that exceeds a preset temperature threshold.

[0069] The temperature threshold is set to 300° C. Once the detected temperature exceeds 300° C., the heat dissipation program is immediately triggered and step S3 is executed.

[0070] S3. Control the spray cooling devices in the same group corresponding to the abnormal detection data to enter the spray cooling state.

[0071] Retrieve the identification code of the same group of spray cooling devices corresponding to the abnormal detection data to obtain the target object, which includes the solenoid valve identity code and water pump identity code of the same group of spray cooling devices; send a control instruction to the corresponding solenoid valve to switch to the open state based on the solenoid valve identity code; obtain the pipeline water pressure of the same group of spray cooling devices, if the pipeline water pressure is lower than the preset pressure value, control the output frequency of the water pump inverter to increase to increase the water supply flow of the water pump; obtain the latest temperature of the cooling area to which the abnormal detection data belongs, if the latest temperature is lower than the temperature threshold, control the corresponding same group of spray cooling devices to exit the spray cooling state.

[0072] For example, if the continuously measured temperature exceeds the set temperature by 200°C (the upper limit can be set on the screen), the control valve in the corresponding area opens to spray and locks the output command (to prevent erroneous stop of spraying). The spray valve closes after a certain delay (which can be set on the screen) when the continuously measured temperature drops by 70°C or above below the set temperature. While the spray valve is operating, a voice alarm is transmitted to the main control room and the duty room to alert the on-duty personnel.

[0073] S4. Close the gas inlet and air inlet of the hot blast stove.

[0074] Determine whether the abnormal detection data exceeds the preset temperature limit: If so, close the gas inlet and air inlet of the hot air furnace; if not, determine whether the spray cooling duration reaches the set time threshold:

[0075] If so, close the gas inlet and air inlet of the hot blast stove.

[0076] For example, if the measured temperature continuously exceeds 500°C, the area will trigger an alarm and spray, while the PLC controls the gas and air valves to close. This prevents any escalating furnace temperature increases. If the measured temperature remains between 200-300°C for more than 15 minutes, the PLC also controls the gas and air valves to close. Computer-recorded and displayed temperatures are updated and transmitted to mobile devices via information system software. Trends are displayed for each high temperature point, allowing equipment managers to easily monitor equipment operating status.

The computer programs of the various program segments in the hot blast stove heat dissipation control system 200 may be stored in a memory of a computer device and executed by at least one processor to perform (see Figure 1 Description) Function of heat dissipation control of hot air stove.
