[0002] Blast furnace humidification involves adding an appropriate amount of steam to the cold blast furnace air, which is then fed into the blast furnace through a hot blast stove. The steam absorbs heat and decomposes, thereby regulating the blast furnace hearth temperature, promoting smooth furnace operation, and increasing blast furnace output.

[0003] Existing steam humidification devices consist of three valves: a manual ball valve, an electric ball valve, and an electric regulating valve. The manual ball valve is used for maintenance, the electric ball valve acts as the main valve, regulating the total flow rate, and the electric regulating valve is mainly used to adjust the steam humidification output.

[0004] The existing technology has the following problems: conventional blast furnace humidification requires blast furnace operators to manually adjust the opening of the steam humidification regulating valve according to the furnace conditions, so as to adjust the humidity of the blast furnace. This has the problems of slow adjustment speed and low adjustment accuracy, and cannot meet the needs of blast furnace condition adjustment. Summary of the Invention

[0009] The air humidity difference is obtained based on the current atmospheric humidity, the target blower humidity, and the current blower humidity.

[0010] Based on the relationship between the air humidity difference and the width of the adjustment dead zone, the opening of the first humidifying steam pipe and / or the second humidifying steam pipe is adjusted to automatically regulate the blast furnace humidity.

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] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Example 1

[0032] Figure 1 The flowchart of an automatic humidity adjustment method for a blast furnace provided in Embodiment 1 of the present invention is applicable to the case of automatic humidity adjustment of a blast furnace. The method can be executed by an automatic humidity adjustment device for a blast furnace equipped with a first humidifying steam pipe and a second humidifying steam pipe. The automatic humidity adjustment device for a blast furnace can be implemented in hardware and / or software and is located in a terminal or server with automatic humidity adjustment function for a blast furnace.

[0033] like Figure 1 As shown, the method includes:

[0034] S110. Obtain preset humidity information and determine whether the target blast furnace is undergoing a furnace replacement operation.

[0035] The preset humidity information includes the target blower humidity, the current atmospheric humidity, the blower pressure difference, and the current blower humidity.

[0036] The humidity information can be manually set and modified through a preset information input interface according to specific industrial working conditions. Furthermore, the humidity represents the dryness or wetness of the air, that is, the physical quantity of the amount of water vapor contained in the air. At a certain temperature, the less water vapor contained in a certain volume of air, the drier the air; the more water vapor, the more humid the air. In this embodiment, the air can be limited to the gas environment inside the blast furnace during the production process.

[0037] The target blast humidity is calculated based on actual production conditions and meets the humidity requirements of the blast furnace's current production environment. Furthermore, the term "blast" refers to the blast machinery installed in metal smelting to ensure complete fuel combustion and increase furnace temperature. Blast kinetic energy increases with the blast furnace volume; reasonable blast kinetic energy requires reasonable air volume and tuyeres area. Different blast furnaces correspond to different blast kinetic energies, necessitating exploration and practice to develop a reasonable blast system and maintain hearth activity over the long term.

[0038] Wherein, the current atmospheric humidity is the air humidity in the current environment where the blast furnace is located, the blast pressure difference is the difference between the air pressure of the blast currently input into the blast furnace and the current ambient air pressure, and the current blast humidity is the humidity of the blast currently input into the blast furnace.

[0039] In this embodiment, determining whether the target blast furnace is undergoing a furnace replacement operation includes: determining whether there is a furnace replacement signal in the target blast furnace; if yes, then determining that the target blast furnace is undergoing a furnace replacement operation; if no, then determining that the target blast furnace is not undergoing a furnace replacement operation.

[0040] In this embodiment, to avoid fluctuations in humidification caused by blast pressure fluctuations during blast furnace replacement affecting furnace temperature regulation, if there is a replacement signal in the current target blast furnace, it can be assumed that a replacement operation is in progress. At this time, the target blast furnace stops tracking the blast pressure of the blast furnace and maintains the current blast humidity unchanged until the replacement signal in the target blast furnace disappears, and then returns to execute the above S110.

[0041] If there is no furnace replacement signal in the current target blast furnace, it can be assumed that there is no furnace replacement operation in the current target blast furnace, and the various copper coefficients of the target blast furnace can be further adjusted according to the steps described in this embodiment.

[0042] S120. Based on the blower pressure difference and the current atmospheric humidity, determine the current air humidity adjustment value, and obtain the adjustment dead zone width based on the current air humidity adjustment value.

[0043] The determination of the current air humidity adjustment value based on the blower pressure difference and the current atmospheric humidity includes: when the value of the blower pressure difference is within a first value range, determining the current air humidity adjustment value as a first fixed value; when the value of the blower pressure difference is within a second value range, determining the current air humidity adjustment value as a second fixed value; and when the value of the blower pressure difference is within a third value range, determining the current air humidity adjustment value as a third fixed value; wherein the first value range is smaller than the second value range, the second value range is smaller than the third value range, the first fixed value is smaller than the second fixed value, and the second fixed value is smaller than the third fixed value.

[0044] For example, the first numerical range can be 4-6, the second numerical range can be 6-8, and the third numerical range can be 8-n, where n is a positive number greater than 8. The first fixed value can be 2, the second fixed value can be 4, and the third fixed value can be 5. Based on the above conditions, specifically, when the blast pressure difference is 5, the air humidity adjustment value of the target blast furnace is 2; when the blast pressure difference is 7.5, the air humidity adjustment value of the target blast furnace is 4; and when the blast pressure difference is 11, the air humidity adjustment value of the target blast furnace is 5.

[0045] Furthermore, the adjustment dead zone width refers to the range of input signals in the transfer function of the control system where the corresponding output is zero. In this embodiment, the adjustment dead zone width refers to the minimum humidity adjustment range in the target blast furnace. For example, if the current adjustment dead zone width is 0.5, then if the humidity difference between the current target blast humidity and the current blast humidity is 0.3, which is less than the adjustment dead zone width of 0.5, then the target blast furnace will not adjust the current blast humidity.

[0046] In this embodiment, the method for calculating the dead zone width is: air humidity adjustment value * K = dead zone width; where K is a width parameter, which is preset or adjusted manually according to actual production and living needs.

[0047] S130. Based on the current atmospheric humidity, the target blower humidity, and the current blower humidity, obtain the air humidity difference.

[0048] Specifically, the calculation method for the air humidity difference is as follows: air humidity difference = current atmospheric humidity + target blast humidity - current blast humidity; wherein, the current atmospheric humidity is the air humidity in the current environment of the blast furnace, the current blast humidity is the humidity of the blast air currently input into the blast furnace, and the target blast humidity is the humidity of the blast air calculated based on the actual production situation, which can meet the current production environment of the blast furnace.

[0049] S140. Based on the relationship between the air humidity difference and the width of the adjustment dead zone, adjust the opening of the first humidifying steam pipe and / or the second humidifying steam pipe to automatically adjust the blast furnace humidity.

[0050] The technical solution of this invention obtains preset humidity information and determines whether the target blast furnace is undergoing a furnace replacement operation. For target blast furnaces without furnace replacement operations, the current air humidity adjustment value is determined based on the blast pressure difference and the current atmospheric humidity. The adjustment dead zone width is obtained based on the current air humidity adjustment value. The air humidity difference is obtained based on the current atmospheric humidity, the target blast humidity, and the current blast humidity. Finally, the opening of the first humidifying steam pipe and / or the second humidifying steam pipe is adjusted according to the relationship between the air humidity difference and the adjustment dead zone width to automatically adjust the blast furnace humidity. This achieves automatic adjustment of blast furnace humidity and improves the control accuracy and adjustment speed of blast furnace humidity.

[0051] Example 2

[0052] Figure 2a This is a flowchart of an automatic humidity adjustment method for a blast furnace provided in Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Specifically, this embodiment refines the method of adjusting the opening of the first humidifying steam pipe and / or the second humidifying steam pipe according to the relationship between the air humidity difference and the width of the adjustment dead zone.

[0053] like Figure 2a As shown, the method includes:

[0054] S210. Obtain preset humidity information and determine whether the target blast furnace is undergoing a furnace replacement operation.

[0055] S220. Based on the blower pressure difference and the current atmospheric humidity, determine the current air humidity adjustment value, and obtain the adjustment dead zone width based on the current air humidity adjustment value.

[0056] S230. Based on the current atmospheric humidity, the target blower humidity, and the current blower humidity, obtain the air humidity difference.

[0057] S240. Determine the relationship between the air humidity difference and the width of the adjustment dead zone;

[0058] If the air humidity difference is greater than the adjustment dead zone width, then execute S250;

[0059] If the air humidity difference is less than the adjustment dead zone width, then execute S260.

[0060] S250, Increase the opening of the first humidifying steam pipe and / or the second humidifying steam pipe.

[0061] Specifically, increasing the opening degree of the first humidifying steam pipe and / or the second humidifying steam pipe includes:

[0062] The system acquires the first current output value of the first humidifying steam pipe of the target blast furnace and the air humidity adjustment value, and obtains a first output target value based on the first current output value and the air humidity adjustment value; it determines whether the current first output target value is greater than 100%; if the first output target value is greater than 100%, it updates the first current output value to 100%, and acquires the second current output value of the second humidifying steam pipe of the target blast furnace and the air humidity adjustment value, and obtains a second output target value based on the second current output value and the air humidity adjustment value; if the first output target value is not greater than 100%, it updates the first current output value to the first output target value, and adjusts the opening of the humidity regulating valve of the target blast furnace based on the updated first current output value; it determines whether the second output target value is greater than 100%; if the second output target value is greater than 100%, it updates the second current output value to 100%, and adjusts the opening of the humidity regulating valve of the target blast furnace based on the updated first current output value and the second current output value.

[0063] In this embodiment, when the current value of the first and / or second output is 100%, it indicates that the opening of the current first humidifying steam pipe and / or the second humidifying steam pipe is at its maximum, that is, the current humidification capacity of the target blast furnace has been adjusted to the maximum capacity of the target blast furnace.

[0064] S260. Reduce the opening of the first humidifying steam pipe and / or the second humidifying steam pipe.

[0065] Specifically, reducing the opening degree of the first humidifying steam pipe and / or the second humidifying steam pipe includes:

[0066] The system acquires the current second output value of the second humidifying steam pipe of the target blast furnace and the air humidity adjustment value, and obtains a second output target value based on the current second output value and the air humidity adjustment value; it then determines whether the current second output target value is greater than 0%; if the second output target value is greater than 0%, it updates the current second output value to the second output target value, and adjusts the opening of the humidity regulating valve of the target blast furnace based on the updated current second output value; if the second output target value is less than 0%, it updates the current second output value to 0%, and acquires the first output value of the first humidifying steam pipe of the target blast furnace. The current value and the air humidity adjustment value are used to obtain a first output target value; it is determined whether the first output target value is greater than 0%; if the first output target value is greater than 0%, the first output current value is updated to the first output target value, and the opening of the humidity regulating valve of the target blast furnace is adjusted based on the updated first output current value and the second output current value; if the first output target value is less than 0%, the first output current value is updated to 0%, and the opening of the humidity regulating valve of the target blast furnace is adjusted based on the updated first output current value and the second output current value.

[0067] It should be noted that when the current value of the first and / or second output is 0%, it indicates that the opening of the current first humidifying steam pipe and / or the second humidifying steam pipe is at its minimum, that is, the current humidification capacity of the target blast furnace has been adjusted to the minimum capacity of the target blast furnace.

[0068] The technical solution of this invention obtains preset humidity information and determines whether the target blast furnace is undergoing a furnace replacement operation. For target blast furnaces without furnace replacement operations, the current air humidity adjustment value is determined based on the blast pressure difference and the current atmospheric humidity. The adjustment dead zone width is obtained based on the current air humidity adjustment value. The air humidity difference is obtained based on the current atmospheric humidity, the target blast humidity, and the current blast humidity. Finally, if the air humidity difference is greater than the adjustment dead zone width, the opening of the first humidifying steam pipe and / or the second humidifying steam pipe is increased; if the air humidity difference is less than the adjustment dead zone width, the opening of the first humidifying steam pipe and / or the second humidifying steam pipe is decreased. This automatically adjusts the blast furnace humidity, achieving automatic adjustment of blast furnace humidity and improving the control accuracy and adjustment speed of blast furnace humidity. Detailed Implementation

[0070] To more clearly illustrate the technical solutions provided by the embodiments of the present invention, this embodiment will briefly introduce a specific implementation scenario obtained according to this embodiment.

The design consists of a first humidification steam pipe, a second humidification steam pipe, a first humidification pipe regulating valve, and a second humidification steam pipe regulating valve. To improve regulation accuracy, the pipe diameter of the second humidification steam pipe is 70%-90% of the diameter of the first humidification steam pipe, but the control accuracy of the regulating valves for both the first and second humidification steam pipes must be completely consistent.

[0074] Step 1: Obtain preset humidity information and determine whether the target blast furnace is undergoing a furnace changeover operation; wherein, the preset humidity information includes target blast humidity, current atmospheric humidity, blast pressure difference, and current blast humidity;

[0075] Step 2: If it is determined that there is no furnace replacement operation in the target blast furnace, then the current air humidity adjustment value is determined based on the blast pressure difference and the current atmospheric humidity, and the adjustment dead zone width is obtained as 0.5 based on the current air humidity adjustment value (this is only an example and is not related to actual use).

[0076] Step 3: Based on the current atmospheric humidity, the target blower humidity, and the current blower humidity, obtain the air humidity difference value 2.

[0077] Step 4: Since the air humidity difference is greater than the adjustment dead zone width, the first output current value of the first humidifying steam pipe of the target blast furnace and the air humidity adjustment value are obtained, and the first output target value of 150% is obtained based on the first output current value and the air humidity adjustment value.

[0078] Step 5: Obtain the current value of the second output of the second humidifying steam pipe of the target blast furnace and the air humidity adjustment value. Based on the current value of the second output and the air humidity adjustment value, obtain the second output target value of 85%.

[0079] Step 6: Update the opening of the first humidifying steam pipe to 100% and the opening of the second steam pipe to 85%.
