Description

TECHNICAL FIELD

[0001] The present application relates to the field of measurement and control technology, and in particular to a converter gas holder tank capacity instrument error correction method and device. BACKGROUND

[0002] The gas holder is one of the important facilities of a steel enterprise, and plays an important role in storing gas, regulating gas pipe network pressure, reasonably using energy, and reducing environmental pollution. The gas holder currently used at home and abroad can be divided into two types: dry-type gas holder and wet-type gas holder. Compared with the wet-type gas holder, the dry-type gas holder has the advantages of long service life, stable gas storage pressure, small pollution, easy operation, and safe operation. The Wiggins type gas holder commonly used for converter gas recovery has the functions of storage, pressure stabilization, and mixing of the converter recovered gas, and has the advantages of large throughput, less routine maintenance and repair workload, and long service life.

[0003] During the production process of a steel enterprise, a large amount of gas is generated. Because the generation and consumption of gas often change greatly, it has a great impact on the gas pipe network. The gas holder effectively alleviates this situation and reduces the pressure fluctuation of the gas pipe network. The gas holder tank capacity detection and piston balance detection are two important indicators for the safe and stable operation of the gas holder.

[0004] At present, the mechanical type tank capacity instrument and the ultrasonic type tank capacity instrument (also including radar type or laser type) are commonly used for detecting the tank capacity of the converter gas holder. The mechanical type tank capacity instrument has one end of a steel wire fixed on the piston and the other end fixed on the outside of the wall plate with a guide rail and a counterweight through a mechanical type tank capacity instrument composed of a corresponding pulley block and gear block. When the piston of the gas holder moves up and down, the mechanical tank capacity instrument displays the change of the tank capacity of the gas holder in real time. However, the pointer and pulley block of the mechanical tank capacity instrument may slip, the mechanical tank capacity instrument cannot correctly display the real-time tank capacity of the gas holder, and misjudgment may occur. In addition, the pointer of the mechanical tank capacity instrument may drop under its own gravity, causing the actual tank capacity of the gas holder to be inconsistent with the display. The ultrasonic type tank capacity instrument (also including radar type or laser type) calculates the piston tank height and the real-time change of the tank capacity by using the distance between the ultrasonic wave hitting the piston and the reflecting plate. However, the inevitable vibration of the gas holder may affect the perpendicularity of the ultrasonic wave, affecting the accuracy of the tank capacity. The cleanliness of the reflecting plate may also affect the scattering of the wave, causing the actual tank capacity of the gas holder to be inconsistent with the display. The fluctuation of the input and output current signals may also cause the actual tank capacity of the gas holder to be inconsistent with the display. SUMMARY

[0005] The application provides a converter gas tank volume meter error correction method and device to solve the error in detecting the volume of the converter gas tank, which leads to the inconsistency between the actual volume and the display of the gas tank, improve the accuracy of detecting the volume of the converter gas tank, and avoid the occurrence of piston toppling accidents.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0035] As one of the important facilities of steel enterprises, the gas holder plays an important role in storing gas, adjusting the pressure of the gas pipe network, reasonably using energy, and reducing environmental pollution. The main function of the gas holder is to store the excess gas when the system is unbalanced, and to reduce the gas emission. When the pressure of the gas pipe network is reduced, the gas stored in the gas holder can be used to supplement the pressure of the pipe network to maintain the normal use of gas by the users within a certain period of time. Secondly, when the gas source is interrupted, the pressure can be maintained to adjust the pressure of the pipe network and ensure safe production. Therefore, the gas holder position and the gas holder capacity are extremely important parameters in the safe operation of the gas holder.

[0036] At present, the mechanical type holder capacity instrument and the ultrasonic type holder position instrument are generally used to detect the gas holder capacity of the converter gas holder. The mechanical type holder capacity instrument adopts a steel wire rope, one end of which is fixed on a piston, and the other end is fixed outside the wall plate of the gas holder with a guide rail and a counterweight after passing through a corresponding pulley group and a gear group. When the piston of the gas holder operates up and down, the mechanical type holder capacity instrument displays the change of the gas holder capacity in real time. However, the pointer and the pulley group of the mechanical type holder capacity instrument will appear "slip" phenomenon, and the mechanical type holder capacity instrument cannot correctly display the real-time gas holder capacity, which is easy to cause misjudgment. In addition, the pointer of the mechanical type holder capacity instrument will "sink" under the action of its own gravity, causing the actual gas holder capacity to be inconsistent with the display. The ultrasonic type holder position instrument (also including radar type or laser type) calculates the real-time change of the piston position height and the gas holder capacity by using the distance between the ultrasonic wave hitting the reflecting plate on the piston. However, the verticality of the ultrasonic wave will be affected by the inevitable vibration of the gas holder operation, which will affect the accuracy of the gas holder capacity. The cleanliness of the reflecting plate will also affect the scattering of the wave, which will also cause the actual gas holder capacity to be inconsistent with the display. The fluctuation of the input and output current signals will also cause the actual gas holder capacity to be inconsistent with the display. Due to the above problems, when the mechanical type holder capacity instrument and the ultrasonic type holder capacity instrument are used to measure the gas holder capacity at the same time, the holder capacity data may not be consistent, and it is difficult to determine which holder capacity instrument displays the accurate holder capacity data.

[0037] In order to solve the above problems, the present application provides a converter gas tank volume meter error correction method and device, by introducing a new gas tank volume data as a basis for judgment, a plurality of tank volume detection data measured by a plurality of tank volume meters (such as mechanical tank volume meter and ultrasonic tank volume meter) are calculated and verified, and the above detection data is corrected. Simple structure, low cost, reliable use, relatively accurate converter gas tank volume, ensure the safe capacity interval operation of gas tank, avoid the occurrence of piston toppling accident.

[0038] In the first aspect, the present application provides a converter gas tank volume meter error correction method, which is applied to a converter gas tank volume meter error correction device. The converter gas tank is cylindrical in shape, and a piston is arranged inside the converter gas tank to move up and down along the inner wall. Gas is stored in the lower part of the piston, and the gas storage capacity of the gas tank is changed by moving the piston up and down. The tank volume meter error correction device includes a steel wire rope and a piston counterweight connected to one end of the steel wire rope. The other end of the steel wire rope is connected to the piston of the gas tank. The piston counterweight extends out of the converter gas tank through the steel wire rope to hang on the side plate of the converter gas tank. It can be understood that during the up and down movement of the gas tank piston, the piston counterweight tightens the steel wire rope, so that the piston counterweight moves correspondingly with the up and down movement of the gas tank piston. For example, when the gas tank piston moves upward, the piston counterweight moves downward.

[0039] The piston counterweight is provided with a controller configured to execute the converter gas tank volume meter error correction method. When the gas tank moves up and down, the controller indirectly obtains the change data of the gas tank volume by calculating the displacement of the piston counterweight caused by the up and down movement of the gas tank piston. The data is compared and verified with the plurality of detection data measured by the plurality of tank volume meters, and the tank volume meter closest to the data is used as the reference. The controller is wirelessly connected to a display, and the display is used to display the change data of the gas tank volume during the up and down movement of the piston counterweight. As shown in the figure, the converter gas tank volume meter error correction method comprises the following steps: Figure 1

[0040] S1, obtain the basic parameters of the converter gas tank, including the rated tank volume, the side plate height, the number of side plates and the piston stroke. Among them, the rated tank volume is the rated design tank volume of the converter gas tank, the side plate height is the height of a single side plate, and the piston stroke is the overall operating stroke of the gas tank piston.

[0041] S2, based on the basic parameters, determine the effective stroke of the piston counterweight, and calculate the unit volume corresponding to the change of the converter gas tank volume per unit stroke of the piston counterweight within the effective stroke.

[0042] ​The step of determining the effective stroke of the piston counterweight based on the basic parameters comprises:

[0043] Obtaining an upper limit height of the piston counterweight when the converter gas tank is in the piston setting state.

[0044] Obtaining a lower limit height of the piston counterweight when the converter gas tank is in the piston top-striking state, the upper limit height and the lower limit height being relative heights of the lower end of the piston counterweight to the side plate of the converter gas tank.

[0045] Based on the upper limit height and the lower limit height, obtaining the effective stroke of the piston counterweight.

[0046] In the embodiment, the piston setting state of the gas tank is a state in which the gas tank is not storing gas and the piston of the gas tank is on the tank bottom plate, at which time the piston counterweight reaches the maximum height relative to the side plate. As the amount of gas stored in the gas tank increases, the piston of the gas tank moves upward, and when the amount of gas stored in the gas tank reaches the maximum amount of gas, the piston of the gas tank is in the top-striking state, i.e., the gas tank is raised to the highest position, at which time the piston counterweight reaches the minimum height relative to the side plate. According to the maximum height and the minimum height of the piston counterweight, the running interval of the piston counterweight relative to the side plate, i.e., the effective stroke of the piston counterweight, is obtained.

[0047] After obtaining the effective stroke of the piston counterweight, the unit volume corresponding to the change in the tank volume of the converter gas tank per unit stroke of the piston counterweight (with the lower end as the reference) needs to be calculated, i.e., the change data of the tank volume of the gas tank. The unit stroke can be 1 meter or 1 zone, which can be set according to actual conditions, and the present application does not limit this.

[0048] Taking the case where the unit stroke is one zone as an example, the converter gas tank includes multiple side plates, and the value of the one zone is a value corresponding to the height of one side plate. The number of side plates of the gas tank is obtained, and according to the number of side plates, the number of effective running zones of the piston counterweight is determined, the number of effective running zones being the number of running zones within the effective stroke. For example, the number of side plates is 20, i.e., the number of zones is 26, and the number of effective running zones of the piston counterweight relative to the side plate is the number of zones between the upper limit height and the lower limit height of the piston counterweight.

[0049] The step of calculating the unit volume corresponding to the change in the tank volume of the converter gas tank per unit stroke of the piston counterweight within the effective stroke comprises:

[0050] Calculating the ratio of the rated tank volume to the piston stroke.

[0051] Calculating the product of the ratio and the unit stroke to obtain the unit volume of the converter gas tank.

[0052] The following is 80000m 3 The converter gas tank is taken as an example to describe the error correction method of the tank volume meter for the converter gas tank.

[0053] The design drawing parameters are as follows: diameter: 58000mm, total height of side plate: 39070mm, piston stroke: 31554mm, height of one side plate: 1500mm, and number of side plates: 26.

[0054] The height of the piston counterweight is 2245mm, as shown in the figure, when the piston is in the "bedding" state, the lower end of the piston counterweight of the gas tank is at the position of the side plate height of 35325mm, and the lower end of the piston counterweight is located near the top of the 24th band. Figure 2 As shown in the figure, when the piston is in the "topping" state, the lower end of the piston counterweight is at a position of about 3750mm of the side plate height, and the lower end of the piston counterweight is located near the top of the 3rd band. The number of running bands of the piston counterweight needs to be reduced by 2 bands above and 3 bands below. The full stroke of the piston of the gas tank runs between the 4th band and the 25th band, that is, the effective running stroke of the piston of the gas tank is 31575mm, and the effective running band number of the piston of the gas tank is 4-25 bands. Figure 3 If the unit stroke is 1m, the unit volume of the gas tank volume change per 1m of the piston counterweight: 80000m 3 ÷31.55m×1m≈2540m 3 .

[0055] If the unit stroke is 1 band, the unit volume of the gas tank volume change per 1.5m (1 band) of the piston counterweight: 2540m 2 ×1.5m≈3800m 3 .

[0056] S3, based on the effective stroke and the unit volume, obtaining a target volume corresponding to a change in the volume of the converter gas tank when the piston counterweight runs to a target position, the target position being a position of the piston counterweight corresponding to at least two detection data of the converter gas tank when at least two tank volume meters detect the detection data of the converter gas tank.

[0057] Wherein, based on the effective stroke and the unit volume, the step of obtaining the target volume corresponding to the change in the volume of the converter gas tank when the piston counterweight runs to the target position comprises:

[0058] According to the effective stroke, determining a target stroke of the piston counterweight running to the target position within the effective stroke.

[0059] Calculating the product of the target stroke and the unit volume to obtain the target volume.

[0060] ​

[0061] S4, based on the target volume, correct the detection data of at least one cabinet volume meter.

[0062] In this embodiment, the aforementioned 80000m 3 Taking the converter gas holder as an example, the two capacity gauges are a mechanical capacity gauge and an ultrasonic capacity gauge. These two gauges are used to measure the capacity of the converter gas holder. The mechanical capacity gauge displays approximately 38,000 m³ / s. 3 The ultrasonic cabinet capacity meter displays 40500m. 3 There is a significant difference between the two sets of data. This was verified by comparing the data using the converter gas holder capacity meter error correction device provided in this application. Figure 4 As shown, when there is a significant difference in the detection data between the mechanical and ultrasonic cabinet volume meters, the piston counterweight moves to... Figure 3 The target position shown indicates that the lower end of the piston counterweight has moved to near the top of the 13th band, meaning the target stroke of the piston counterweight is 11 bands. For each band, the change in the converter gas holder volume corresponds to a unit volume of 3800 m³. 3 The target volume is: 11 × 3800 ≈ 41800 m³ 3 Using this data as a basis for judgment, the detection data obtained by the mechanical and ultrasonic gas holder volume meters were calculated and verified. The calculation showed that the difference in piston height between the two detection data was approximately 1 meter. After comparison and verification, the ultrasonic gas holder volume meter was found to be closer to the actual volume of the gas holder. Therefore, the display of the ultrasonic gas holder volume meter was taken as the standard, and the detection data of the mechanical gas holder volume meter was corrected based on the calculation and verification results.

[0063] In summary, the application provides a converter gas tank volume gauge error correction method and device, which is applied to a converter gas tank volume gauge error correction device. The converter gas tank is provided with a gas tank piston. The volume gauge error correction device comprises a steel wire rope and a piston counterweight connected to one end of the steel wire rope. The other end of the steel wire rope is connected to the gas tank piston. The piston counterweight extends out of the converter gas tank through the steel wire rope to be hung on the side plate of the converter gas tank. The method comprises the following steps: obtaining basic parameters of the converter gas tank, which include rated tank volume, side plate height, side plate number and piston stroke; determining the effective stroke of the piston counterweight based on the basic parameters, and calculating the unit volume corresponding to the change of the converter gas tank volume per unit stroke of the piston counterweight within the effective stroke; obtaining the target volume corresponding to the change of the converter gas tank volume when the piston counterweight runs to the target position based on the effective stroke and the unit volume, the target position being the position of the piston counterweight corresponding to at least two detection data of the converter gas tank detected by at least two volume gauges; and correcting the detection data of at least one volume gauge based on the target volume. By introducing a new gas tank volume data as a basis for judgment, the multiple volume gauges (such as mechanical volume gauges and ultrasonic volume gauges) measure multiple volume data, which are calculated and verified, and the above detection data is corrected. The structure is simple, the cost is low, and the use is reliable.
