Description

Technical Field

[0001] The present invention relates to the technical field of iron and steel metallurgy, and in particular to a carbon footprint tracking method for dust ash returned to sintering, which is suitable for the full-process tracking of the properties, quality, origin, destination and absorption time of dust ash during the comprehensive utilization of dust ash by steel plants. Background Art

[0002] At present, the dust ash digested by sintering batching includes dry ash from steelmaking, high carbon ash from the transportation department's dumper when unloading coke, low carbon ash from unloading lump ore, as well as sintering self-produced ash and blast furnace iron-making field ash. Among them, the converter dry ash enters the 7# dry ash bin with large mixing, high carbon ash enters the 8# bin, low carbon ash enters the 6# bin, iron-making field ash enters the 4# bin, and raw material ash enters the 5# bin. For sintering batching, the status tracking of the entire dust ash is blank. The post personnel manually contact the ash suction team of the transportation department to suck ash according to the ash level status of the dust collector. The intermediate process, including the ash suction source, the suction quality, the ash suction time and the suction process of the ash suction vehicle, cannot be controlled, which to a certain extent makes it impossible to ensure the normal flow distribution of dust ash. Summary of the invention

[0003] The object of the present invention is to provide a method for tracking the carbon footprint of dust ash returned to sintering.

[0004] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0005] A method for tracking the carbon footprint of dust ash returned to sintering, comprising the following steps performed in sequence:

[0006] 1) Planned uploading of the internal material transfer system: When the transfer team performs the ash collection operation according to the ash collection plan, they manually queue up the ash collection vehicles in order, scan the code at the ash collection point first, the code is the location code, and select the vehicle number and dust collector name of the ash collection vehicle. The information is saved as the vehicle card information in the form of ERP number, vehicle number / type, plan number / location by the internal material transfer system. When entering the weighing process of the metering system, the information is confirmed by the metering system as interactive information;

[0007] 2) Single vehicle tracking process during continuous operation: The ash collection vehicle collects ash point by point according to the operation plan and ash collection sequence. At each planned ash collection point, the driver's scanned code information is transmitted to the internal material transfer system as the vehicle's card information. At the same time, the internal material transfer system also pushes this information to the dust collection tracking system. The dust collection tracking system compares the material attributes of this operation information with the material attributes of the previous operation. If there is any inconsistency, an alarm will be issued to prompt the sintering batching staff to intervene manually. If there is a consistency, the receiving location, plan number, and ERP number of this business process will be automatically recorded. While recording, the dust collection tracking system interacts with the metering system to obtain the corresponding weighing information of the record;

[0008] 3) Dust collection tracking process: The tracking process is to obtain the starting point, intermediate links, suction volume of each dust collection point and the final destination determined by material properties of the dust collection vehicle by indexing the dust collection vehicle number during the operation;

[0009] 4) Flow monitoring of dust collection tracking system: Post personnel or management personnel monitor the status in real time through HMI or mobile phone APP. The dust collection status is green, which means that the dust collection point has been collected, and gray, which means that it has not been collected. The name of the dust collector that has been collected is displayed in green, and the name of the dust collector that has not been collected is displayed in gray;

[0010] The dust suction sequence indicates the station where the dust collector is sucked during the operation of the dust suction vehicle. 1 is the first station, 2 is the second station, and n is the nth station.

[0011] The mixed material alarm pop-up box is used to ensure that the dust suction vehicle sucks dust of the same properties in the process operation. When the dust properties of the dust to be sucked by scanning the code are inconsistent with the dust properties of the previous site, the mixed material alarm pop-up box will pop up to prompt;

[0012] After the ash suction truck completes a process of ash suction operation, when it arrives at the destination ash discharge point to discharge the ash, the driver scans the QR code of the ash discharge point, and the previous information of the process is automatically cleared. After discharging the ash, the ash suction truck executes the next ash suction process.

[0013] Preferably, the ash amount management of the dust collector: the ash amount produced per unit time of each dust collector is known, and each ash bin of each dust collector is provided with a material level meter, through which the material level can be monitored to determine the ash amount in the bin;

[0014] The ash amount at the current time is calculated by the ash production per unit time and time. After the ash suction truck has sucked out the ash in the dust collector bin, the ash amount obtained by the dust collector ash tracking system can be used to verify and calculate the ash production of the dust collector, thereby realizing the dust collector ash amount management in coordination with the material level meter.

[0015] The present application has achieved the following beneficial technical effects:

[0016] The internal material transfer system and the metering system are organically combined, and the platforms and data of these two systems are used to realize the dynamic tracking of the carbon footprint of dust removal ash, that is, the tracking design of the carbon footprint of dust removal ash;

[0017] The internal material transfer system uses the Internet of Things technology. Each dust collection point has a QR code. The driver enters the home page and clicks the scan code floating button to open the "scan code viewfinder" page to select the vehicle being driven, the vehicle number, the name of the dust collection point being operated, and the properties of the dust collected. After the code is scanned successfully, the plan binding information is read by the metering system. After the internal transfer plan is successfully submitted, the metering system will generate a scheduled task with the vehicle number as the key to monitor whether the vehicle has completed the weight inspection.

[0018] In order to improve the utilization efficiency of the ash suction vehicle, the ash suction vehicle is usually transported continuously during operation. It scans the code once, sucks the ash from one point, and weighs once. The corresponding weighing information in the metering system is pushed to the dust removal ash tracking system and displayed. The content includes the vehicle number, the name of the ash suction point, the ash properties, quality, plan number, and weighing time, so as to achieve the tracking purpose.

[0019] In this application, the sintering batching room staff can remotely monitor the ash suction amount, transportation route, and dust removal ash properties of the next ash suction point at the ash suction truck at the operation ash suction point. If they are not consistent, they can promptly alarm and manually intervene to contact and remind the transportation driver;

[0020] In this application, the dust storage capacity of each dust collector is comprehensively calculated based on the daily discharge and delivery volume of each dust collector, and the operation plan of the dust suction vehicle is reasonably arranged to avoid the situation where the dust used for sintering ingredients is greatly increased or reduced;

[0021] The application of this method can remotely monitor the quality and properties of the ash sucked by the ash sucking vehicle at each ash sucking point at any time, and can promptly alarm and prompt when the properties are inconsistent to avoid mixing;

[0022] At the same time, according to the ash production, conveying capacity and storage capacity of each dust collector, combined with the operating effect of the dust collector, we guide and arrange the ash suction and discharge operation plan to optimize the operating capacity of the dust collector.

[0042] The present application provides a carbon footprint tracking method for dust ash returned to sintering, comprising the following steps performed in sequence:

[0043] 1) Planned uploading of the internal material transfer system: When the transfer team performs the ash collection operation according to the ash collection plan, in order to improve the utilization and efficiency of the vehicles, they will artificially queue the ash collection order. At the ash collection point, they will first scan the code, which is the location code, and select the vehicle number and dust collector name of the ash collection vehicle. The information is saved in the form of ERP number, vehicle number / type, plan number / location as the vehicle card information by the internal material transfer system. When entering the actual weighing process of the metering system, the information is confirmed as interactive information;

[0044] 2) Single vehicle tracking process during continuous operation: The ash collection vehicle collects ash point by point according to the operation plan and ash collection sequence. At each planned ash collection point, the driver's code scanning information is transmitted to the internal material transfer system as the vehicle's card information. At the same time, the internal material transfer system also pushes this information to the dust collection tracking system. The dust collection tracking system compares the material attributes of this operation information with the material attributes of the previous operation. If there is any inconsistency, an alarm will be issued to prompt the sintering batching personnel to intervene manually. If there is any consistency, the receiving location, plan number, and ERP number of this business process will be automatically recorded. While recording, the dust collection tracking system will interact with the metering system at any time to obtain the corresponding weighing information of the record;

[0045] 3) Dust collection tracking process: The tracking process is to obtain the starting point, intermediate links, suction volume of each dust collection point and the final destination determined by material properties by indexing the dust collection vehicle number during the operation;

[0046] 4) Flow monitoring of the tracking system: Post personnel or managers can monitor the status in real time through HMI or mobile phone APP. The green dust absorption status indicates that the dust absorption point has been absorbed, and the gray one indicates that it has not been absorbed. The name of the dust collector that has been absorbed is green, and the name of the dust collector that has not been absorbed is gray;

[0047] The dust suction sequence indicates the station where the dust collector is sucked during the operation of the dust suction vehicle. 1 is the first station, 2 is the second station, n is the nth station, and so on.

[0048] The mixed material alarm pop-up box is designed to ensure that the dust suction vehicle sucks dust of the same properties in the process operation. When the properties of the dust to be sucked by scanning the code are inconsistent with the properties of the dust at the previous station, the mixed material alarm pop-up box pops up to prompt;

[0049] After the ash suction truck completes a process of ash suction operation, when it arrives at the destination ash discharge point to discharge the ash, the driver scans the QR code of the ash discharge point, and the previous information of the process is automatically cleared. After discharging the ash, the ash suction truck executes the next ash suction process.

[0050] In one embodiment of the present application, the ash amount of the dust collector is transparently managed with the material level: during normal production, the ash production per unit time of each dust collector is basically fixed, and each ash bin has a material level meter, through which the ash level can be monitored to achieve simple judgment of the ash amount;

[0051] Because the ash production per unit time is basically fixed, the ash production at the current time can be deduced through time. When the ash suction truck is sucking out the ash in a dust collector bin, the ash production obtained by the dust collector ash tracking system can be verified and deduced to calculate the ash production of the dust collector, thereby realizing transparent management of the ash production of the dust collector in conjunction with the material level meter.

[0052] In this application, the internal material transfer system is referred to as the transfer system, and the dust removal ash tracking system is referred to as the tracking system.

[0053] The contents (%) and proportions (%) in this application are all mass percentages.

It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
