[0017] In this example, the coordinate system includes the three-dimensional coordinates of the slug at every coordinate point, the slug constituents by pattern mapping, and the slug temperature by color mapping parameters.

[0018] In this embodiment, the temperature field includes second temperature values ​​of the slug at all boundary and non-boundary points within all finite elements.

[0019] In this example, the temperature gradient represents the direction in which the temperature of the slug at a coordinate point changes most rapidly and the amount of change per unit distance.

[0020] In this embodiment, the temperature change function represents the temperature change rule of the slag at the coordinate point under the action of cold air.

[0021] In this embodiment, each three-dimensional coordinate in the coordinate system corresponds to one second temperature value, each three-dimensional coordinate corresponds to one temperature gradient, and each three-dimensional coordinate corresponds to one temperature conversion function.

[0022] In this embodiment, the control command system determines control commands for the air-cooling equipment and the steel belt based on the first information and the second information monitored in real time, for example, the control commands may be to adjust the cold air speed, change the conveyor speed, change the cold air direction, increase the cold air flow rate, etc.

[0023] The advantageous effects of the above technical solution are as follows: by monitoring the air-cooling equipment and the steel belt in real time to determine the first information and the second information, analyzing the second information to construct a coordinate system, determine the temperature field, calculate the temperature gradient, and determine the temperature change function, and generating control commands according to the first information, the temperature field, the temperature gradient, and the temperature change function, the monitoring data can be analyzed in real time, and flexible and accurate control commands can be generated, which can realize intelligent real-time control of the air-cooled steel belt dry slag discharger, improve the slag treatment efficiency, and enhance the stability and reliability of the system. [Example]

[0024] An embodiment of the present invention provides a control system for an intelligent air-cooled steel belt mounted dry slag discharger, wherein the first information includes a cold air temperature, a cold air speed, a cold air direction, a cold air flow rate and a hot air temperature of the air-cooling device; The second information includes slag components, slag locations, and slag temperatures corresponding to the slag locations.

[0025] In this embodiment, the hot slag passes through a slag pit, the door is closed and the slag falls onto a conveyor in a continuously operating dry slag discharger, the slag moves slowly on the conveyor and is finally stored in a slag storage room and periodically removed.

[0026] In this embodiment, the hot air is produced when cold air enters the dry slag discharger in the opposite direction and exchanges heat with the slag on the conveyor. As a result, the temperature of the slag drops and the temperature of the cold air rises, becoming hot air.

[0027] In this embodiment, the hot air flows in the opposite direction along the slag pit into the boiler, and on the way into the furnace, the hot air exchanges heat with the high-temperature slag again sufficiently, causing the temperature of the slag to drop and the temperature of the hot air to rise, becoming hot air.

[0028] In this embodiment, the composition of the slag is determined by the type of blast furnace slag that the steel belt-mounted dry slag discharger processes. For example, when processing coal combustion slag, the slag composition includes ash, fly ash, bottom ash, and coal slag.

[0029] In this example, the slag properties are determined by the boiler fuel. For example, example slag properties are shown in Table 1.1. JPEG0007825089000017.jpg112161

[0030] In this embodiment, the position of the slug can be detected in real time using a position sensor such as an encoder or a laser distance measuring sensor.

[0031] In this embodiment, the first information and the second information are detected in real time using sensors. For example, the position of the slug can be detected using a laser distance measurement sensor, and the temperature of the slug, the cold air temperature, and the hot air temperature can be detected using a temperature sensor.

[0032] The advantageous effects of the above technical solution are as follows: by determining the first information and the second information, the information of the air-cooling equipment and the steel belt is obtained in real time, and data support is provided for the generation of smart control strategies and commands.

[0034] In this example, the mapping pattern is to map different slag components with different patterns when processing coal combustion slag, such as the pattern mapping of ashes, fly ash, bottom ash and coal slag being represented as triangle, circle, oval and square, respectively.

[0035] In this example, the slag mapping pattern is filled based on the color mapping parameters of the slag temperature, e.g., a blue to red gradient from low to high temperature, with low temperature slag being blue and high temperature slag being red.

[0036] In this example, a coordinate system visualizes the slag position, slag temperature, and slag composition of all slags. As shown in FIG. 3, the horizontal axis is hz and the vertical axis is sz, with (hz, sz) representing a coordinate point in the coordinate system. For example, if there are three coordinate points, they are (hz1, sz1), (hz2, sz2), and (hz3, sz3), respectively. The content concrete representations at each coordinate are A1, A2, and A3, respectively. Here, A1 is a circle, a square, and a triangle, representing fly ash, coal slag, and ash, respectively; A2 is a circle and a square, representing fly ash and coal slag, respectively; and A3 is an oval and a triangle, representing bottom ash and ash, respectively. The circle, square, and triangle use different fill colors, and each color corresponds to a different grayscale (each grayscale corresponds to a different slag temperature).

[0037] The advantageous effects of the above technical solution are as follows: by setting the mapping pattern, color mapping parameters, and combining the slag position to construct a coordinate system, the slag position and temperature distribution can be visualized, the changes in slag position and temperature distribution can be monitored in real time, the slag processing efficiency can be improved, the system control strategy can be optimized, and the accuracy of the control command can be improved.

[0039] In this embodiment, the finite elements may be triangles, quadrilaterals, tetrahedrons, hexahedrons, or the like.

[0040] In this embodiment, the coordinate system is divided into a number of finite elements.

[0041] In this embodiment, the coordinate system is meshed to determine finite elements based on the color mapping parameter range of the slag, and the coordinate system is divided into small regions to accurately visualize the slag temperature of the slag in each finite element. Each finite element can include iN1 non-boundary coordinate points and iN2 boundary coordinate points, and the number of coordinate points within each finite element can also be different.

[0042] In this embodiment, one boundary coordinate point includes N1 boundary conditions.

[0043] In this embodiment, the boundary conditions represent limiting conditions for the slag temperature, including thermal conductivity and convection coefficient, among which the thermal conductivity represents the heat conduction condition between the slag and the steel belt, and the convection coefficient represents the heat conduction condition when the cold air and the slag come into contact and conduct heat.

[0044] In this embodiment, the second temperature value represents the temperature of the slug at each coordinate point after it has been affected by the slugs at other non-boundary coordinate points and boundary coordinate points within the corresponding finite element.

[0045] The advantageous effects of the above technical solution are as follows: by dividing the finite elements, calculating the second temperature value of the slag at each coordinate point within each finite element, determining the temperature field T, and performing a refined analytical calculation on the slag temperature at each coordinate point, the resolution and accuracy of the temperature field can be improved, the system control strategy can be optimized, and the accuracy of the control command can be improved.
