Technical Field

The invention relates to the technical field of blast furnace ironmaking, in particular to a tuyere layout regulation and control method and a tuyere layout regulation and control device.

In the process of the blast furnace production process, the blast furnace gas flow is distributed for three times, namely upper regulation, middle regulation and lower regulation. The upper part adjustment is simplest and fastest, and the rapid adjustment can be realized by a single batch of material distribution angles, ore batch sizes, material distribution turns and the like; the middle adjustment means that the distribution of gas flow in the furnace is adjusted by improving the metallurgical performance of ores and realizing the up-and-down movement of a reflow zone, the adjustment can be realized by changing the types of ores, adjusting a cooling system and the like, the adjustment period is relatively fast, and the adjustment can be realized by one shift generally; the lower part adjustment, which generally includes adjusting the air speed, air pressure, air distribution and other aspects of the tuyere, is very difficult to realize the quick and accurate lower part adjustment, and can be realized only in the damping down state of the blast furnace.

When the activity of the blast furnace hearth is deteriorated due to fluctuation of the furnace condition of the blast furnace, or the productivity is reduced or increased due to the production situation, the lower regulation is required.

FIG. 4 is a flowchart of a tuyere layout regulation and control method according to an embodiment of the present invention, which is applicable to a case of regulating a lower tuyere during a blast furnace smelting production process. The method can be executed by a tuyere layout regulating and controlling device, the tuyere layout regulating and controlling device can be realized in a hardware and/or software mode, and the tuyere layout regulating and controlling device can be configured on blast furnace regulating and controlling equipment. As shown in fig. 4, the method includes:

s110, acquiring total furnace entering parameters of the air supply main pipe within a preset time length under the condition that the air supply main pipe and the at least one air supply branch pipe are in a working state, and determining whether the total furnace entering parameters and the preset main pipe furnace entering parameters meet a first type preset proportional function.

The air supply main pipe is a main pipe which is arranged at the bottom of the blast furnace and is directly connected with the hot blast furnace, and as shown in fig. 2, the main pipe on the left side in fig. 2 is the air supply main pipe. The air supply branch pipes are a plurality of branch pipes led out from an air supply main pipe, as shown in fig. 2, the air supply branch pipes 1, the air supply branch pipes 2 and the air supply branch pipes 3 on the right side in fig. 2 are all air supply branch pipes, the number of the air supply branch pipes can be a plurality, and the air supply branch pipes are arranged in advance in the blast furnace equipment and the construction process and are fixed according to the scale size of the blast furnace and the actual production requirement. The preset time period is a preset time period, for example, the preset time period may be 1 hour. The total furnace entering parameters are parameter information corresponding to the air supply main pipe acquired by the detection device, and include total furnace entering air quantity and total furnace entering pressure, wherein the total furnace entering air quantity can be provided by an air quantity meter arranged in the main pipe, and the total furnace entering pressure can be provided by a high-temperature pressure resistant detection device. The preset main pipe furnace entering parameters comprise a preset air volume and a preset air pressure, the preset air volume is a standard total furnace entering air volume preset according to production requirements, and the preset air pressure is a standard total furnace entering pressure preset according to the production requirements. The first type preset proportion function is a proportion function determined according to a large number of historical total furnace inlet parameters in a good state of the blast furnace, for example, the first type preset proportion function can be represented as y1= K1 (x) + b1, wherein y is the variation of the total furnace inlet air quantity of the blast furnace in the good state, and x is the variation of the total furnace inlet pressure of the blast furnace in the good state.

Specifically, in the process of smelting production of the blast furnace, when the blast furnace is in a working state, the air supply main pipe and the at least one air supply branch pipe of the blast furnace are also in a corresponding working state. In the working process of an air supply main pipe and an air supply branch pipe of a blast furnace, acquiring total furnace inlet air quantity and total furnace inlet pressure of the air supply main pipe within a preset time length, comparing the actually acquired total furnace inlet air quantity and total furnace inlet pressure with standard total furnace inlet air quantity and standard total furnace inlet pressure which are set in advance according to production requirements, comparing the actually acquired total furnace inlet air quantity and the actually acquired total furnace inlet pressure with a first type preset proportional function, and finally judging whether the total furnace inlet parameters meet the first type preset proportional function.

Optionally, determining whether the total furnace entering parameters and the preset total furnace entering parameters satisfy a first type preset proportional function, includes: acquiring total furnace inlet air volume and total furnace inlet pressure at each moment within a preset time length, and determining air volume variation of the total furnace inlet air volume and pressure variation of the total furnace inlet pressure at two adjacent moments; and determining whether a first type preset proportional function is met or not based on the air volume change, the pressure change, the preset air volume in the preset main pipe furnace entering parameter and the preset air pressure.

In the present embodiment, the total furnace inlet air volume and the total furnace inlet pressure at each time within the preset time period are obtained, for example, the total furnace inlet air volume and the total furnace inlet pressure of the blast furnace at each time within 1 hour are obtained. Obtaining the variable quantity of the air quantity by performing difference operation on the total air quantity entering the furnace at two adjacent moments; and obtaining the pressure variation by calculating the total furnace pressure difference of two adjacent moments. In the practical application process, if the air volume of the blast furnace air supply pipeline is increased relative to the preset air volume, the pressure of the corresponding blast furnace air supply pipeline is also increased relative to the preset pressure, and if the air volume of the blast furnace air supply pipeline is reduced relative to the preset air volume, the pressure of the corresponding blast furnace air supply pipeline is also reduced relative to the preset pressure, so that the actually obtained total air volume entering the furnace and the total pressure entering the furnace can be compared with the preset air volume and the preset pressure which are preset according to production requirements, and whether the first type preset proportional function is met or not is determined. And then comparing the function relation between the air volume variation and the pressure variation with a first type preset proportion function, and finally judging whether the total furnace entering parameters meet the first type preset proportion function.

Further, based on each amount of wind variation, pressure variation, the preset amount of wind and the preset wind pressure in the preset total pipe furnace entering parameter, whether a first type of preset proportional function is satisfied is determined, including: if the total furnace entering air volume is larger than the preset air volume and the total furnace entering pressure is reduced, determining that the first-type preset proportional function is not met based on the fact that the target function corresponding to the air volume variation, the pressure variation, the preset air volume and the preset air pressure is different from the first-type preset proportional function.

The objective function is a functional relation between the blast furnace air supply main pipe air volume variation and the pressure variation, which are calculated according to a plurality of groups of air volume variations and pressure variations in a preset time period.

In this embodiment, if the total furnace entering air volume is greater than the preset air volume, it indicates that the total furnace entering air volume is increased, and when the state of the blast furnace is good, when the total furnace entering air volume is increased, the corresponding total furnace entering pressure is inevitably increased, but the detected furnace entering pressure is decreased, so that the target function corresponding to the air volume variation, the pressure variation, the preset air volume and the preset air pressure is different from the first-type preset proportional function, and in this case, it is determined that the obtained total furnace entering air volume and the total furnace entering pressure do not satisfy the first-type preset proportional function.

For example, assuming that the preset air volume and the preset air pressure in the preset main pipe furnace entering parameter within a preset time of 1 hour are determined to be 5000m/min and 0.4Mpa according to a specific production index, the first type preset proportional function may be represented as y1= K1 (x) + b1. Acquiring total furnace inlet air volume and total furnace inlet pressure of an air supply main pipe at each moment within 1 hour of a preset time length, and calculating a difference value between the total furnace inlet air volume corresponding to a termination moment of the preset time length and the total furnace inlet air volume corresponding to an initial moment of the preset time length to be used as main pipe air volume to be compared; and calculating the difference between the total furnace entering pressure corresponding to the ending moment of the preset time length and the total furnace entering pressure corresponding to the starting moment of the preset time length to be used as the pressure to be contrasted of the main pipe. And comparing the air volume to be compared with the preset air volume at 5000m/min, comparing the pressure to be compared with the preset air pressure at 0.4Mpa, if the air volume to be compared is larger than the preset air volume and the pressure to be compared is larger than the preset air pressure, comparing the calculated objective function with a first type preset proportional function according to a plurality of groups of air volume variable quantities and pressure variable quantities within a preset time length, judging whether the air volume to be compared and the preset air volume are consistent, and further judging that the first type preset proportional function is met. If the air volume to be compared is larger than the preset air volume and the pressure to be compared is smaller than the preset air pressure, the first type preset proportional function is not satisfied.

S120, if not, determining whether the branch pipe furnace entering parameters and the preset branch pipe furnace entering parameters of the at least one air supply branch pipe meet a second type preset proportional function.

The branch pipe furnace entering parameters comprise a branch pipe furnace entering air quantity and a branch pipe furnace entering pressure, wherein the branch pipe furnace entering air quantity can be provided by an air quantity meter arranged in the branch pipe, and the branch pipe furnace entering pressure can be provided by a high-temperature-resistant pressure detection device. The preset branch pipe furnace entering parameters comprise a preset air volume and a preset air pressure, and because the high-pressure hot air in the branch pipes is obtained by shunting the air supply main pipe, the preset air volume in the main pipe furnace entering parameters and the total quantity of the branch pipes can be obtained so as to obtain the preset air volume of each branch pipe, and according to the shunting non-pressure-dividing principle, the preset air pressure of the branch pipes is the same as the preset air pressure of the main pipe. The second type of preset proportional function is a proportional function determined according to a large number of historical air supply branch inlet parameters of the blast furnace in a good state, for example, the second type of preset proportional function may be represented as y2= K2 (x) + b2, where y is a variation of an inlet air quantity of the blast furnace in the good state, and x is a variation of an inlet pressure of the blast furnace in the good state.

In this embodiment, if the total furnace entering parameter and the preset total furnace entering parameter do not satisfy the first type preset proportional function, the furnace entering air volume of the branch pipe of the blast furnace and the furnace entering pressure of the branch pipe at each moment in the preset time are obtained, and the difference value between the furnace entering air volume of the branch pipe corresponding to the end moment of the preset time length and the furnace entering air volume of the branch pipe corresponding to the start moment of the preset time length is calculated and used as the air volume to be compared of the branch pipe; and calculating the difference value between the branch pipe furnace entering pressure corresponding to the end moment of the preset time length and the branch pipe furnace entering pressure corresponding to the start moment of the preset time length to serve as the branch pipe to-be-contrasted pressure. The method comprises the steps of comparing the air volume to be compared of a branch pipe with a preset air volume of the branch pipe, comparing the pressure to be compared of the branch pipe with a preset air pressure of the branch pipe, if the air volume to be compared of the branch pipe is larger than the preset air volume of the branch pipe, and the pressure to be compared of the branch pipe is larger than the preset air pressure of the branch pipe, comparing the function relation between the air volume variation of the branch pipe and the pressure variation of the branch pipe with a second type preset proportional function, judging whether the two functions are the same, if the two functions are the same, indicating that the furnace entering parameter of the branch pipe meets the second type preset proportional function, and if the two functions are different, indicating that the furnace entering parameter of the branch pipe does not meet the second type preset proportional function. If the air volume to be compared of the branch pipe is larger than the preset air volume and the pressure to be compared of the branch pipe is smaller than the preset air pressure, the second type preset proportional function is not satisfied.

Further, if the total charging parameters and the preset total charging parameters meet a first type preset proportional function, and the branch charging parameters and the preset branch charging parameters meet a second type preset proportional function, adjusting the top pressure value of the blast furnace equipment according to the pressure boosting parameters under the condition of increasing the ore batch weight.

The ore batch weight is the quality of the ore part in a batch of materials loaded in the blast furnace, and the smelting efficiency of the blast furnace can be improved by properly increasing the ore batch weight in the production process. The pressure supercharging parameter is the variable quantity of the air pressure in the blast furnace before the ore batch weight is increased by the blast furnace and after the ore batch weight is increased by the blast furnace. The pressure value of the furnace top can be adjusted by an adjusting pressure device arranged in the blast furnace.

In this embodiment, if the total furnace entering parameter and the preset main pipe furnace entering parameter satisfy the first type preset proportional function, and the branch pipe furnace entering parameter and the preset branch pipe furnace entering parameter satisfy the second type preset proportional function, it indicates that the blast kinetic energy of the blast main pipe and the blast branch pipe of the blast furnace is increased, and the blast around the blast furnace cylinder is uniform and stable. Under the condition, the intensified smelting production can be executed under the premise of unchanged energy consumption, and the beneficial effect of further improving the productivity is achieved. In the process of strengthening smelting production, a process of increasing the batch weight of ores can be adopted, and the productivity is further improved. When the ore batch weight is properly increased, the air pressure in the blast furnace can be changed due to the increase of the ore batch weight, the change amount of the pressure in the blast furnace is determined before the ore batch weight is increased in the blast furnace and after the ore batch weight is increased in the blast furnace, and the value of the top of the blast furnace is adjusted to be half of the pressure supercharging parameter through a pressure adjusting device arranged in the blast furnace, so that the blast furnace has the advantages that: by adjusting the blast pressure of the furnace top, the pressure difference between the furnace bottom and the furnace top is kept balanced, so that the blast furnace can discharge more smoothly, and the productivity can be improved finally.

And S130, determining a target processing mode of the blast furnace equipment according to the judgment result, and adjusting the tuyere area of the central air supply main pipe and/or at least one air supply branch pipe of the blast furnace equipment based on the target processing mode.

And the target processing mode is a specific mode for determining the lower adjustment of the blast furnace equipment according to the judgment result.

Optionally, the target processing mode includes adjusting the tuyere area of the main air supply pipe and/or the branch air supply pipe in the lower tuyere of the blast furnace equipment.

In this embodiment, the target processing manner may include adjusting only the area of the air inlet of the air supply main pipe, adjusting the area of the air inlets of some specific branch pipes of the air supply branch pipes, or adjusting the areas of the air inlets of the air supply main pipe and the air supply branch pipes simultaneously.

In the embodiment, if the total furnace entering parameter of the main pipe and the preset main pipe furnace entering parameter do not meet the first type preset proportional function, the area of the air inlet of the air supply main pipe is adjusted; and if the branch pipe furnace entering parameter of only one air supply branch pipe and the preset branch pipe furnace entering parameter do not meet the second type preset proportional function, adjusting the area of the air port corresponding to the air supply branch pipe.

Optionally, determining a target processing manner for the blast furnace equipment according to the judgment result includes:

and if the judgment result is that the second preset type proportion function is not met, determining a target processing mode for the blast furnace equipment based on the main pipe furnace entering parameter, the branch pipe furnace entering parameter, the preset branch pipe furnace entering parameter and the preset main pipe furnace entering parameter.

In this embodiment, if the branch pipe furnace-entering parameter and the preset branch pipe furnace-entering parameter of the air supply branch pipe do not satisfy the second type preset proportional function, the target processing mode at this time includes adjusting the tuyere areas of the air supply main pipe and the air supply branch pipe.

Optionally, on the basis of the foregoing embodiment, if the air volume of at least one air supply branch pipe is continuously reduced in the preset period, and the total air supply volume of the air supply main pipe is not changed, the area of the air inlet of at least one air supply branch pipe is increased or the number of air supply branch pipes is reduced.

In this embodiment, for each blast furnace air supply branch pipe, the branch pipe air volume is collected every preset period, when the air volume of one or more blast branch pipes is continuously reduced and the total blast furnace air volume is not reduced, it is prompted that the furnace hearth in the area of the branch pipe air vents is inactive, the corresponding air supply branch pipe air vents need to be adjusted, and an operator needs to pay attention to the smelting state in the area. When the lower part is adjusted, the air inlet area of the air supply branch pipe air inlet in the area needs to be enlarged, the air inlet with the increased branch pipe flow is synchronously reduced, and the total air inlet area is kept unchanged. For example, if the blast furnace is configured with 20 branch pipes altogether, and the detection shows that under the premise that the total air supply amount of the air supply main pipe is not changed, the air volume of 5 branch pipes is continuously reduced in a preset period, the area of the air ports of the 5 branch pipes is increased, and meanwhile, the air ports of 15 branch pipes which are not continuously reduced in the preset period can be partially closed.

According to the technical scheme provided by the embodiment of the invention, when the air supply main pipe and the at least one air supply branch pipe are in a working state, the total furnace entering parameter of the air supply main pipe within a preset time is obtained, whether the total furnace entering parameter and the preset main pipe furnace entering parameter meet a first type preset proportional function is further determined, if yes, the arrangement of the blast furnace tuyere is reasonable at the moment, the smelting production can be strengthened, if not, whether the branch pipe furnace entering parameter and the preset branch pipe furnace entering parameter of the at least one air supply branch pipe meet a second type preset proportional function is further determined, then, according to a judgment result, a target processing mode for the blast furnace equipment is determined, and the tuyere area of the middle air supply main pipe and/or the at least one air supply branch pipe of the blast furnace equipment is adjusted based on the target processing mode. The scheme compares the relation between the air quantity and the pressure of the blast furnace running in real time with a preset proportion function, adjusts the air port area of the air supply main pipe or the air supply branch pipe in real time according to the comparison result, solves the technical problem that the air port arrangement of the blast furnace is adjusted according to artificial subjective judgment, has extremely low accuracy, ensures that the air port arrangement of the blast furnace is adjusted more reasonably, improves the uniform stability of air supply around the air port, saves energy consumption and improves the energy utilization rate of the blast furnace.

Example two

Fig. 5 is a flowchart of a tuyere layout regulation and control method provided in the second embodiment of the present invention, and the second embodiment of the present invention further refines the content corresponding to the foregoing embodiments S120 to S130 on the basis of the foregoing embodiments, and the second embodiment of the present invention may be combined with each alternative in one or more of the above embodiments. As shown in fig. 5, the method includes:

s210, acquiring total furnace entering parameters of the air supply main pipe within a preset time length under the condition that the air supply main pipe and the at least one air supply branch pipe are in a working state, and determining whether the total furnace entering parameters and the preset main pipe furnace entering parameters meet a first type preset proportional function.

S220, acquiring branch pipe furnace inlet air quantity and branch pipe furnace inlet pressure of the corresponding air supply branch pipe at each moment within preset time based on a high-temperature-resistant pressure detection device arranged at the inlet of each air supply branch pipe.

In this embodiment, it is necessary to arrange a high temperature resistant pressure detecting device at the inlet end of each branch pipe branched from the blast main pipe of the blast furnace during the new construction of the blast furnace, for detecting the hot air pressure at the inlet area of each branch pipe. The arrangement position of the high temperature resistant pressure detection device in the branch pipe is shown in fig. 2, and in fig. 2, the rectangular device at the inlet end of each branch pipe represents the high temperature resistant pressure detection device.

It should be noted that, after the blast furnace is built, because the air supply main pipe is a closed pipeline built by refractory bricks, the installation is most reasonable when the blast furnace is newly built, and the blast furnace in the production process does not have the condition for implementing the technology; the installation is also not suitable in the area below the air supply branch pipe, each branch pipe separated from the high-pressure hot air main pipe is connected with a transition pipe formed about 1 m below the high-pressure hot air main pipe, then the transition pipe is connected with a middle-section pipeline and a blow pipe of a blast furnace tuyere and finally enters the interior of the blast furnace, the middle section pipeline, the blow pipe and the tuyere sleeve are all daily consumption parts, and the transition pipe is generally damaged and needs to be replaced after being used for several months or dozens of months, so the pressure detection position of each branch pipe is only most suitable at the inlet end of the branch pipe separated from the air supply main pipe.

In this embodiment, the entry end of each branch pipe all disposes high temperature resistant pressure detection device, and in the practical application process, the branch pipe income stove air volume and the branch pipe income stove pressure of each air supply branch pipe each moment in the length of presetting are obtained by high temperature resistant pressure detection device.

And S230, determining whether a second preset type proportion function is met or not based on the branch pipe furnace inlet air quantity and the corresponding branch pipe furnace inlet pressure at each moment.

In the embodiment, the furnace inlet air volume and the furnace inlet pressure of each branch pipe of the blast furnace at each moment in the preset time are obtained, and the branch pipe air volume variation is obtained by performing difference operation on the furnace inlet air volumes of the branch pipes at two adjacent moments; and obtaining the pressure variation of the branch pipe by calculating the pressure difference of the branch pipe entering the furnace at two adjacent moments. Then, according to the air quantity variation of a plurality of groups of branch pipes and the pressure variation of the branch pipes within a preset time length, calculating a branch pipe objective function, further comparing the branch pipe objective function with a second type preset proportional function, judging whether the branch pipe objective function and the second type preset proportional function are consistent, and if the branch pipe objective function is the same as the second type preset proportional function, indicating that the furnace inlet air quantity of the branch pipe and the corresponding furnace inlet pressure of the branch pipe meet the second preset type proportional function; if the branch pipe target function is different from the second type preset proportional function, the branch pipe furnace inlet air quantity and the corresponding branch pipe furnace inlet pressure do not meet the second type preset proportional function.

S240, determining a first variation coefficient according to the main pipe furnace entering parameter, the branch pipe furnace entering parameter, the preset branch pipe furnace entering parameter and the preset main pipe furnace entering parameter.

In this embodiment, the first variation coefficient is a coefficient corresponding to a proportional function determined by the actually obtained main pipe furnace inlet air volume variation and the actually obtained main pipe furnace inlet pressure variation, and a coefficient corresponding to a proportional function determined by the actually obtained branch pipe furnace inlet air volume variation and the actually obtained branch pipe furnace inlet pressure variation.
