The dry quenching environmental protection pressure is lower, but the investment is higher, and the popularization is difficult.

The embodiment of the application provides a coke quenching method, which can be used for realizing the accurate control of water sprinkling in the coke quenching process, ensuring the extinguishing of coke and reducing the water consumption and the sewage generation amount.
Fig. 1 is a flowchart of a quenching method according to an embodiment of the present application, and referring to fig. 1, the quenching method according to the embodiment of the present application specifically includes the following steps:
s1, image data of the loading tool 100 for loading coke is acquired.
The loading tool 100 may be embodied as a quenching car, for example, as shown in fig. 3, the quenching car is a vehicle running on a rail for receiving coke guided by the coke guide car, transporting the coke to a quenching chamber for quenching, and finally transporting the quenched coke to a designated location. Of course, the loading tool 100 is not limited to a quench car, but may be other types of loading tools 100.
When the coke quenching car runs on the track, the identification device identifies the identification code and sends the identified identification code to the control system, and the control system automatically controls the track to change the fork according to the programmed production plan to ensure that the coke quenching car enters the normal coke quenching tank.
The coke quenching device is characterized in that a position sensor and an image acquisition device can be further arranged at a necessary preset position of the coke quenching car, the position sensor sends a signal to the control system when sensing that the coke quenching car runs to the preset position, the control system receives the signal to control the coke quenching car to stop running, and then the image acquisition device is controlled to acquire image data, or the control system can also directly control the image acquisition device to acquire the image data of the coke quenching tool.
In practical applications, the image data of the loading tool 100 may be acquired by one image acquisition device, or the image data of the loading tool 100 may be acquired by a plurality of image acquisition devices from different viewpoints, for example, the image data may be acquired by two image acquisition devices from two sides of the loading tool 100.
It should be noted that acquiring the image data is not limited to the data acquisition operation performed by the image acquisition apparatus, but may be, for example, a data transmission operation in which the processing device or the control device acquires the image data from the image acquisition apparatus based on a communication path.
S2, determining the loading capacity of the loading tool 100 based on the image data.
The loading capacity can be the volume of the coke loaded by the loading tool 100, or the mass of the coke loaded by the loading tool 100. After the image data is acquired, the shape parameters of the coke loaded in the loading tool 100 may be acquired based on image recognition techniques.
In one case, the shape parameters are obtained and the volume of coke loaded in the loading tool 100 is calculated based on a particular algorithm, and the mass of coke loaded is then determined based on the density of the coke. When the loading tool 100 is a quench car, the bed of the quench car is generally rectangular and the length, width and height of the quench car are of a fixed vertical dimension, and when loading coke, the bottom of the coke pile is generally the same as the length and width of the quench car, but the height of the coke pile is indeterminate. Therefore, the length parameter and the width parameter of the coke pile do not need to be acquired based on the image data, and the height parameter of the coke pile can be acquired based on the image data, namely, the shape parameter of the coke comprises the height parameter, and then the volume and the mass of the loaded coke can be calculated through a specific algorithm based on the preset length parameter and the preset width parameter and the acquired height parameter.
In another case, a three-dimensional model of the coke loaded in the loading tool 100 may be constructed based on the acquired shape parameters, and the volume of the coke, as well as the mass of the coke, can be accurately determined based on the constructed three-dimensional model. Still taking the loading tool 100 as an example of a coke quenching car, the length parameter and the width parameter of the coke pile can be obtained based on the preset length and width of the coke quenching car, and the height parameter matrix of the coke pile can be obtained based on the analysis of the image data, that is, the height parameters of a plurality of measuring points of the coke pile are determined. And then, constructing a three-dimensional model of the coke pile based on the preset length parameter and width parameter and the acquired height parameter matrix, determining the volume of the loaded coke based on the constructed three-dimensional model, and then determining the quality of the coke.
S3, determining the watering amount based on the loading amount; wherein the water spray is an amount of water spray required to lower the temperature of the coke from a first temperature to a second temperature by spraying water to the coke loaded by the loading tool 100 in a quenching chamber.
Specifically, the first temperature is the initial temperature of the coke prior to quenching, and the first temperature is generally 950 ℃ to 1100 ℃; the second temperature is the target temperature for the quenching process, and the second temperature is typically below 250 ℃. Of course, the first and second temperatures are also relevant to the coking process, as well as the process of handling the coke after quenching.
After determining the loading amount of the coke loaded by the loading tool 100, the energy to be released for lowering the coke loaded by the loading tool 100 from the first temperature to the second temperature can be determined based on the acquired first temperature and second temperature, and the released energy should be the same as or substantially the same as the absorbed heat during the water temperature rise and the state change based on the law of conservation of energy. Thus, the amount of water required to reduce the temperature of the coke from the first temperature to the second temperature can be determined based on the amount of heat that needs to be absorbed during the change from the initial temperature to steam for a unit volume of water.
And S4, after the loading tool 100 enters the quenching chamber, controlling a water sprinkling device in the quenching chamber to sprinkle water on the coke loaded on the loading tool 100 based on the sprinkling amount so as to quench the coke.
The coke quenching chamber is a coke quenching chamber in the coke quenching tank, and during specific implementation, a position sensor can be arranged in the coke quenching chamber, and when sensing that the coke quenching car runs to a preset position of the coke quenching chamber, the position sensor can send a signal to a control system, and the control system controls the coke quenching car to stop and controls the coke quenching tank to close the door. In practice, various sensors in the quenching chamber, such as temperature sensors, pressure sensors and the like, can also be started through the control system, and an exhaust system, a drainage system and the like are started. The water spray device is then turned on and controlled based on the determined amount of water spray to spray water onto the coke loaded by the loading tool 100 for quenching purposes. Typically, the coke can be visually lowered to the second temperature when the actual water spray reaches the determined water spray neck.
According to the quenching method, the loading capacity of the loading tool 100 can be determined based on the acquired image data of the loading tool 100 of the coke, the sprinkling quantity required for reducing the temperature of the coke to the target temperature can be accurately determined based on the law of energy conservation, the sprinkling device is controlled to perform sprinkling operation based on the determined sprinkling quantity, the temperature of the coke can be reduced to the target temperature, the purpose of quenching is achieved, and the water consumption and the sewage yield can be reduced.
As shown in fig. 2, in some embodiments, the performing body (i.e., the quenching system) of the quenching method may include an image collecting device for collecting image data of the loading tool 100 and storing the image data with the real-time server, an analysis module for acquiring the image data from the real-time server and determining a loading amount and a sprinkling amount based on the image data, and a control unit connected to the sprinkling device for controlling the sprinkling device to perform a sprinkling operation based on an analysis result of the analysis module. The real-time server is used for storing image data of the loading tools 100 which are performing the quenching operation and intermediate data such as loading capacity, sprinkling quantity and the like determined according to the image data, and the analysis module is beneficial to shortening the reaction time of the quenching system because the speed of retrieving the data from the real-time server is high. After quenching is completed, the image data and the related intermediate data of the quenching operation are stored to a history server for retrieval. In some preferred embodiments, the history server may further be connected to the cloud server through a communication module so as to be able to send the history data to the cloud server, and the cloud server may be accessed by related personnel, such as a manager, a technician, a research and development staff, through a mobile terminal or a fixed terminal to obtain the history data. The quenching system may also include a display device coupled to the analysis module for receiving display data from the analysis module and displaying corresponding display content, such as image data, load capacity, water spray, current temperature of the coke, and air pressure within the quenching chamber.
In practice, the top of the coke pile in the loading tool 100 is usually uneven, such as a ridge, and therefore, the height of the coke pile at different positions is different, which results in different loading capacity per unit area at different positions of the loading tool 100 and different required water spraying amount. If the water is uniformly sprayed, the water in partial areas is excessive, and the water in partial areas is deficient. To address this technical problem, in some embodiments, the sprinkler includes a plurality of spray head assemblies dispersedly disposed in the quenching chamber, each of the spray head assemblies having a corresponding spray area 110 on the loading tool 100; the determining of the loading capacity of the loading tool 100 based on the image data comprises:
determining a zone charge of coke loaded by each of the spray zones 110 based on the image data, wherein the charge is the sum of all of the zone charges.
Specifically, a plurality of spray head assemblies may be arranged in an array in the quenching chamber, for example, a quenching car with a length, width and height of 12m, 6m and 5.7m, six spray head assemblies may be arranged along the width direction, and twelve spray head assemblies may be arranged along the length direction, such that the spray area 110 of each spray head assembly is a square area of 1m by 1m, and the entire quenching car is divided into 72 spray areas 110, i.e., a1, a2, A3 … … F12 as shown in fig. 3.
Upon acquiring the image data, the zone loading of each spray zone 110 may be determined based on image recognition techniques. There are a number of ways to determine zone loading, and in one embodiment, the determining zone loading of coke loaded in each of the spray zones 110 based on the image data may include:
determining a zone loading height of coke loaded by each of the spray zones 110 based on the image data;
the zone loading of coke loaded by each of the spray zones 110 is determined based on the zone loading height of coke loaded by each of the spray zones 110, respectively.
Taking a square area with a 1m by 1m spray area 110 as an example, the coke height at the four vertices of the square area can be determined by image recognition techniques, and then the area loading height can be determined based on the coke heights at the four vertices, which can be regarded as the average height of the spray area 110. Based on the determined zone loading height, and the length and width of the spray zone 110, the coke loading volume can be calculated, and the coke mass can be determined. Of course, the loading height at the center point of the square area may be directly determined, and the loading height at the center point may be used as the area loading height. In another embodiment, after the shape parameters of the coke loaded by the coke quenching car are obtained based on the image recognition technology, a three-dimensional model of the loaded coke can be constructed based on the shape parameters, then the three-dimensional model is divided into a plurality of sub-models, and the regional loading capacity can be determined based on the sub-models. It should be noted that the above method for determining the zone loading is only exemplary.
In some embodiments, said determining the amount of watering based on said loading comprises:
determining an area water spray based on the area load of each of the spray areas 110, wherein the water spray is the sum of all of the area water sprays required by each of the spray head assemblies to lower the temperature of the coke from the first temperature to the second temperature by spraying water through the spray head assemblies in the quenching chamber to the corresponding spray area 110.
Generally, the coke loaded by the loading tool 100 has different heights in different areas, resulting in different area loading amounts of the coke located in different spraying areas 110, if uniform spraying is carried out, the spraying amount of partial areas is too much, the residual water forms sewage to be discharged, the spraying amount of partial areas is too little, and the coke is not completely extinguished.
Therefore, after determining the zone loading for each spray zone 110, the required zone spray for each zone, i.e., the spray required during the process of lowering the coke for that spray zone 110 from the first temperature to the second temperature, may be determined based on the zone loading. In particular implementations, the coke loaded in the spray zone 110 can be determined based on the zone loading, the energy released to decrease from the first temperature to the second temperature can be determined based on the law of conservation of energy, and the desired amount of water spray can be determined. Thus, the area water spray amount corresponding to each spray area 110 can be accurately determined, and the coke is extinguished, and the water consumption and the amount of sewage generated can be further reduced.
In some embodiments, the method further comprises:
determining a temperature parameter of the coke loaded by each spray zone 110; wherein the temperature parameters include coke temperature at a plurality of points within the spray zone 110;
accordingly, said determining an area water spray based on the area load of each of said spray areas 110 comprises:
determining the zone watering amount based on the temperature parameter and the zone loading amount.
In one embodiment, a temperature sensor may be disposed at a predetermined position, and when the loading tool 100 moves to the predetermined position, the temperature sensor collects temperature parameters of different spraying regions 110 in the loading tool 100. In a preferred embodiment, a plurality of temperature sensors may be respectively disposed in a plurality of directions to respectively acquire temperature parameters of different spraying regions 110 in the loading tool 100 from different angles through the plurality of temperature sensors.
In one embodiment, after the temperature parameter is obtained, an average temperature of the coke within the spray area 110 may be determined based on the obtained temperature parameter. For example, when the temperature parameter includes the coke temperature at N measuring points in the spraying area 110, the average temperature may be calculated based on an averaging algorithm and used as the first temperature of the spraying area 110, and the first temperature of each spraying area 110 determined in this way may not be the same, and then the area water spray of each spraying area 110 may be accurately determined based on the first temperature and the area load of the spraying area 110 and the second temperature which is uniformly preset.
In another embodiment, after the temperature parameters are obtained, a temperature field model of the coke in the spraying area 110 may be constructed based on the obtained temperature parameters, and then the energy required to be released by the coke in the spraying area 110 to reduce from the current temperature to the second temperature may be accurately calculated based on the temperature field model and a sub-model formed based on three-dimensional model division, so that the area water spray required by the spraying area 110 may be accurately determined.
In some embodiments, the controlling the sprinkling water by the sprinkling device in the quenching chamber to the coke loaded by the loading tool 100 based on the area sprinkling water amount comprises:
controlling the sprinkling of the corresponding sprinkler assembly to the corresponding sprinkling area 110 based on the area sprinkling amount.
After the area application amount is determined, the application of water by the respective nozzle assembly to its corresponding application area 110 may be controlled based on the application amount. Since the determined amount of water to be sprayed to each spraying area 110 corresponds to the energy contained in the coke loaded in the spraying area 110, the amount of water to be sprayed to the spraying area 110 based on the amount of water to be sprayed can achieve the purpose of extinguishing the coke and can minimize the amount of water consumption and the amount of sewage generated. In specific implementation, the spray head assembly may include only one spray head, or may include a plurality of regularly arranged spray heads.
In some embodiments, said controlling the watering of the corresponding said spray head assembly to the corresponding said spray area 110 based on said area watering amount comprises:
determining a first flow rate for the respective nozzle assembly based on the area water spray;
controlling a plurality of the spray head assemblies to simultaneously spray water to the corresponding spray areas 110 based on the first flow rate.
In order to avoid that each spray head assembly sprinkles water asynchronously, which causes heat transfer among cokes in each sprinkling area 110 to affect coke quenching, each spray head assembly can be controlled to sprinkle water synchronously in practical application. An optimal application time may be determined based on empirical data, and after determining the amount of area application, a first flow rate for each spray head assembly may be determined based on the application time. The corresponding nozzle assemblies are then controlled to simultaneously spray water based on the first flow rate to ensure that the actual amount of water sprayed during the time of spraying corresponds to the determined area spray amount.
In some embodiments, after the sprinkling of water to the coke loaded by the loading tool 100 by a sprinkler in the quenching chamber is completed based on the water sprinkling amount control, the method further comprises:
acquiring gas pressure and gas temperature in the quenching chamber;
controlling the sprinkler to continue sprinkling water to the coke loaded by the loading tool 100 when the gas pressure reaches a first threshold value and/or the gas temperature reaches a second threshold value.
After the water spraying is completed, in order to confirm whether the coke is quenched (i.e., has been reduced below the target temperature), a temperature sensor and a pressure sensor may be provided in the quenching chamber, the gas pressure and the gas temperature in the quenching chamber may be detected by the pressure sensor and the temperature sensor, respectively, and a first threshold corresponding to the gas pressure and a second threshold corresponding to the gas temperature may be provided. And when the gas pressure is less than the first threshold value and the gas temperature is less than the second threshold value, the coke can be confirmed to be extinguished, when the gas pressure reaches the first threshold value and/or the gas temperature reaches the second threshold value, the coke is deemed not to be extinguished completely, the water sprinkling device can be controlled to continue sprinkling water, the gas pressure and the gas temperature in the quenching chamber can be detected in real time, and when the gas pressure is less than the first threshold value and the gas temperature is less than the second threshold value, the water sprinkling device is controlled to stop sprinkling water. In this way, coke quenching can be ensured.
