Description

Technical Field

[0002] The rotary kiln is the core equipment of the raw material calcination process in the new dry process cement production process. It provides the required temperature and a certain residence time for the complete decomposition of raw materials and the formation of clinker minerals to achieve the burning of clinker. Its operating status directly affects the quality and output of cement clinker, and is also related to energy consumption and environmental pollution. The rotary kiln is generally a rotatable long cylinder with an inclination of about 15 degrees. The material moves from the kiln tail to the kiln head under the action of gravity. The direction of the gas is exactly opposite to the direction of the material path under the action of high-temperature fan exhaust. The raw material and hot gas form a suspended heat exchange in the reverse process, and violent chemical and physical reactions occur inside the rotary kiln, eventually forming clinker.

[0003] The interior of the rotary kiln involves complex heat transfer and chemical reaction processes. The temperature, atmosphere and chemical reactions in different areas affect each other. It is a multivariable, large hysteresis, strong coupling, nonlinear time-varying system, and the regional division is very complex.

[0035] Embodiment 1

[0036] Figure 1 A flowchart of a rotary kiln simulation data visualization method is provided for the first embodiment of the present invention. This embodiment is applicable to the rotary kiln simulation data visualization situation. The method can be executed by a rotary kiln simulation data visualization device. The rotary kiln simulation data visualization device can be implemented in the form of hardware and / or software. The rotary kiln simulation data visualization device can be configured in a computer controller. Figure 1 As shown, the method includes:

[0037] S110, obtaining rotary kiln simulation result data, and extracting temperature information from the simulation result data.

[0038] Among them, the rotary kiln refers to a rotary calcining kiln, which belongs to the category of building materials equipment. The temperature information includes the position coordinates and the temperature value, and the temperature value refers to the gas temperature in the rotary kiln.

[0039] Optionally, obtaining rotary kiln simulation result data includes: obtaining historical simulation data of the rotary kiln within a specified time range; and filtering the historical simulation data according to a specified storage directory to obtain simulation result data corresponding to the specified storage directory.

[0040] Specifically, the controller will obtain the rotary kiln simulation result data within the specified time range. The specified time range is set by the user in the controller according to the data reading needs. The controller refers to a computer controller for data visualization. At the same time, the user can also specify a storage directory. The controller will filter the simulation result data according to the specified storage directory to obtain the specified rotary kiln simulation result data to be read. Exemplarily, the specified storage directory can be E: / kiln. It should be noted that the technical solution of this embodiment does not limit the file type of the simulation result data, and supports a variety of simulation methods and simulation calculation software.

[0041] Optionally, temperature information is extracted from the simulation result data, including: establishing a coordinate system based on the rotary kiln, and obtaining a spatial point set by the user based on the coordinate system, wherein the spatial point is located in the rotary kiln; extracting the temperature value of each spatial point from the simulation result data, and using the position coordinates and temperature values ​​corresponding to the spatial point as temperature information.

[0042] Specifically, when the user inputs the structural diagram corresponding to the rotary kiln through the terminal device, the controller can establish a coordinate system for the rotary kiln. The coordinate system refers to a three-dimensional rectangular coordinate system, including an x-axis, a y-axis, a z-axis and an origin. The purpose of establishing the coordinate system is to use coordinates to represent the specific position inside the rotary kiln, so that the controller can locate each area of ​​the rotary kiln. Exemplarily, the upper left corner of the rotary kiln is used as the coordinate origin, the positive half axis of the x-axis is the axis extending from the origin to the tail of the rotary kiln, the positive half axis of the y-axis is the axis perpendicular to the x-axis in the horizontal direction from the origin, and the positive half axis of the z-axis is the axis perpendicular to the x-axis in the vertical direction from the origin, with every 10 cm as the spacing, that is, every 10 cm represents the number 1. In this embodiment, only the upper left corner of the rotary kiln structural diagram is used as the coordinate origin for explanation, and the specific establishment method of the coordinate system is not limited. Furthermore, the user can set a spatial point in the rotary kiln based on the established coordinate system, and the controller will extract the temperature value of each spatial point from the simulation result data, and use the position coordinates and temperature values ​​corresponding to the spatial point as temperature information.

[0043] S120. Divide the rotary kiln into component areas according to the temperature information, wherein the component areas include a drying area, a calcining area, a firing area, and a cooling area.

[0044] It should be noted that dividing the rotary kiln into different areas can optimize the cement production process so that different process steps can be carried out under appropriate conditions, thereby improving production efficiency, reducing energy consumption, ensuring product quality, and ensuring stable operation of the equipment. First, since different areas in the rotary kiln have different requirements for temperature values, such as the calcination process needs to gradually increase the temperature to ensure that the material decomposes and reacts, dividing the area according to temperature information helps to carry out different stages of reaction within the appropriate temperature range, thereby improving product quality and output; secondly, different areas in the rotary kiln may involve different chemical reactions, requiring different atmospheres and reaction conditions. Dividing the area allows each reaction step to be carried out under the most suitable conditions to ensure that the reaction is fully carried out; finally, different areas of the rotary kiln differ in temperature values ​​and heat energy distribution. By dividing the area, the transfer and utilization of heat energy can be better managed, thereby reducing energy consumption and improving energy utilization efficiency. In summary, dividing the component areas of the rotary kiln according to temperature information is to fully consider the multi-faceted characteristics and requirements of the calcination process, so as to optimize the production process, improve product quality, reduce energy consumption, ensure environmental protection, and ensure stable operation of the equipment. So that each calcination stage is carried out under the most suitable conditions to achieve the best production effect.

[0045] Figure 2 A flowchart of a rotary kiln simulation data visualization method is provided for the first embodiment of the present invention, wherein step S120 mainly includes the following steps S121 to S124:

[0046] S121. Generate each divided cross section of the rotary kiln based on the coordinate system, and determine the target space point included in each divided cross section.

[0047] S122, calculating the average temperature value of each target space point of the same divided section, and taking the average temperature value as the target temperature value corresponding to each divided section.

[0048] S123, determining the horizontal coordinate corresponding to each divided cross section, and mapping each target temperature value to the horizontal axis of the coordinate system according to the horizontal coordinate to generate a temperature coordinate axis.

[0049] Specifically, the controller can divide the rotary kiln in the horizontal direction based on the established coordinate system to generate multiple divided sections, and calculate the average temperature value of the spatial points contained in each divided section as the target temperature value corresponding to each divided section. Then, the target temperature value of each divided section is mapped to the horizontal axis of the coordinate system to generate a temperature coordinate axis.

[0050] S124. Divide the component areas of the rotary kiln according to the temperature coordinate axis and the temperature threshold.

[0051] Optionally, the component areas of the rotary kiln are divided according to the temperature coordinate axis and the temperature threshold, including: taking the position in the temperature coordinate axis where the target temperature value is greater than or equal to the first temperature threshold and the horizontal coordinate is the smallest as the first area dividing point, and dividing the rotary kiln area before the first area dividing point into a drying area; taking the position in the temperature coordinate axis other than the drying area where the target temperature value is greater than or equal to the second temperature threshold and the horizontal coordinate is the smallest as the second area dividing point, and dividing the rotary kiln area between the first area dividing point and the second area dividing point into a calcining area; taking the position in the temperature coordinate axis other than the drying area and the calcining area where the target temperature value is less than the third temperature threshold and the horizontal coordinate is the smallest as the third area dividing point, dividing the rotary kiln area between the second area dividing point and the third area dividing point into a firing area, and dividing the rotary kiln area after the third area dividing point into a cooling area.

[0052] Specifically, the component areas of the rotary kiln include the drying area, calcining area, firing area and cooling area from the kiln head to the kiln tail. Since the chemical reaction conditions involved in different component areas are different, the corresponding temperature values ​​are also different, so the user can set the temperature threshold according to each component area. For example, the drying area needs to undergo carbonate decomposition reaction, that is, a large amount of calcium carbonate (CaCO3) and a small amount of magnesium carbonate (MgCO3) in the limestone decompose to release carbon dioxide (CO2) during the calcination process. The decomposition of carbonate is an endothermic reaction, so the increase in temperature will lead to an acceleration of the decomposition rate. Usually, for every 50°C increase in temperature, the decomposition rate will increase by about one time year-on-year. When the raw material temperature rises to 900°C, the decomposition of carbonate will proceed rapidly. About 80% of the raw material is CaCO3. The reaction rate of CaCO3 directly determines the firing rate of the clinker. The temperature of the drying area is usually around 1100 degrees from the kiln tail to the kiln. The calcining zone needs to undergo a solid phase reaction, that is, during the calcination of cement clinker, while carbonates decompose, a solid phase reaction occurs between the limestone component and the clay component in the raw material. The temperature of the calcining zone is about 1100 to 1280 degrees. The burning zone needs to burn clinker, and the temperature range of the burning zone should be controlled between 1280 to 1450 to 1300 degrees. The temperature of the cooling zone should generally be lower than 1300 degrees. Exemplarily, the first temperature threshold may be 1100 degrees, and the controller may use the position in the temperature coordinate axis where the target temperature value is greater than or equal to 1100 degrees and the horizontal coordinate is the smallest as the first area dividing point, and divide the rotary kiln area before the first area dividing point into a drying area; then the controller continues to traverse in the positive direction of the horizontal axis (towards the tail of the kiln) according to the second temperature threshold, and the second temperature threshold may be 1280 degrees, that is, the controller uses the position in the temperature coordinate axis except the drying area where the target temperature value is greater than or equal to 1280 degrees and the horizontal coordinate is the smallest as the second area dividing point, and then divides the rotary kiln area between the first area dividing point and the second area dividing point into a calcining area, and then the controller continues to traverse in the positive direction of the horizontal axis (towards the tail of the kiln) according to the third temperature threshold, and the third temperature threshold may be 1300 degrees, and uses the position in the temperature coordinate axis except the drying area and the calcining area where the target temperature value is less than 1300 degrees and the horizontal coordinate is the smallest as the third area dividing point, and divides the rotary kiln area between the second area dividing point and the third area dividing point into a firing area, and divides the rotary kiln area after the third area dividing point into a cooling area. That is, the controller will divide the rotary kiln into a drying zone, a calcining zone, a firing zone and a cooling zone in sequence from left to right along the horizontal axis according to the temperature threshold.

[0053] Furthermore, the controller can also draw a temperature cloud map of the rotary kiln, that is, map different temperature values ​​to different display colors, set the temperature mapping range according to the highest temperature value and the lowest temperature value, map the lowest temperature value to blue, and the highest temperature value to red. The remaining intermediate temperature values ​​can be mapped in order of high and low temperature values ​​to intermediate colors such as green, yellow, and orange.

[0054] S130, determining the mass fraction of key components in each component region, and visualizing the rotary kiln simulation data according to the mass fraction of the key components.

[0055] Specifically, the controller can determine the mass fraction of key components in each component area and visualize the rotary kiln simulation data. It should be noted that the main material composition of the drying area is calcium carbonate, and the temperature is relatively low. Its main goal is to remove moisture from the raw materials to reduce the heat required for the evaporation of moisture in the kiln, because directly calcining the wet raw materials will consume a lot of heat energy to evaporate the moisture, resulting in energy waste and unnecessary costs; the material composition of the calcining area is calcium carbonate, calcium oxide, etc., and the temperature is relatively high. The main purpose of the calcining area is to decompose calcium carbonate to generate calcium oxide and carbon dioxide, and to ensure that the cement raw material limestone is decomposed as completely as possible. The main material composition of the burning area is cement clinker, and the temperature is the highest. The high temperature promotes the chemical reaction of calcium oxide with other components (such as aluminum oxide in clay) to form a complex mineral phase and crystal structure-cement clinker. The temperature of the clinker directly affects the mineral phase transformation and crystallization of the cement clinker in the burning area, as well as the quality and performance of the final cement. The main material composition of the cooling zone is cement clinker, which has a lower temperature. The main purpose of the cooling zone is to introduce cooling airflow to stabilize the crystal structure of the clinker and ensure the quality and performance of the final cement product. By cooling the clinker to a temperature suitable for storage and subsequent processing, it is convenient for subsequent grinding and mixing. Users can select the key components of each component area as needed, and through data visualization, users can timely judge whether the components of each component area are within the normal range through mass fractions, and then judge whether the corresponding chemical reactions in the component area occur normally.

[0056] The technical solution of the embodiment of the present invention divides the component areas of the rotary kiln into a drying area, a calcining area, a firing area and a cooling area through temperature information, and determines the mass fraction of the key components of each component area to realize the visualization of temperature values ​​and mass fractions of different key components at designated positions in different areas of the rotary kiln, so that researchers can more intuitively view and analyze the operating status data of different areas in the rotary kiln, study the changing laws of material composition in different areas of the rotary kiln under different operating conditions, explore the optimal operating conditions of the rotary kiln, improve production efficiency, reduce energy consumption, and ensure product quality.

The specific contents of steps S210-S220 are roughly the same as steps S110-S120 in the first embodiment, so they will not be repeated in this embodiment. Figure 3 As shown, the method includes:

[0059] S210, obtaining rotary kiln simulation result data, and extracting temperature information from the simulation result data.

[0064] Optionally, the component areas of the rotary kiln are divided according to the temperature coordinate axis and the temperature threshold, including: taking the position in the temperature coordinate axis where the target temperature value is greater than or equal to the first temperature threshold and the horizontal coordinate is the smallest as the first area dividing point, and dividing the rotary kiln area before the first area dividing point into a drying area; taking the position in the temperature coordinate axis other than the drying area where the target temperature value is greater than or equal to the second temperature threshold and the horizontal coordinate is the smallest as the second area dividing point, and dividing the rotary kiln area between the first area dividing point and the second area dividing point into a calcining area; taking the position in the temperature coordinate axis other than the drying area and the calcining area where the target temperature value is less than the third temperature threshold and the horizontal coordinate is the smallest as the third area dividing point, dividing the rotary kiln area between the second area dividing point and the third area dividing point into a firing area, and dividing the rotary kiln area after the third area dividing point into a cooling area.

[0065] S230. Determine the mass fraction of key components in each component region.

[0067] Specifically, the controller can extract the components of each component area from the simulation result data, and obtain the key components set by the user based on the components. For example, the key components of the drying area can be water and carbonate, the key components of the calcining area can be carbonate, and the key components of the burning area can be carbonate and various components in the clinker. The controller will take the mass corresponding to the key component as the target mass, and calculate the ratio of the target mass to the total mass to determine the mass fraction of the key component.

[0068] S240: Acquire a designated position, and determine a target component area corresponding to the designated position, wherein the designated position is a default position or a user-set position.

[0069] Specifically, the designated position is a default position or a user-set position. The default position refers to a typical position in different areas of the rotary kiln, generally at the center of the area, and the user-set position can be a position determined by a user clicking a mouse on the rotary kiln visualization interface.

[0070] S250, screening the mass fractions of key components according to the target composition region to obtain a target mass fraction corresponding to the target composition region.

[0073] The technical solution of the embodiment of the present invention divides the component areas of the rotary kiln into a drying area, a calcining area, a firing area and a cooling area through temperature information, and determines the mass fraction of the key components of each component area to realize the visualization of temperature values ​​and mass fractions of different key components at designated positions in different areas of the rotary kiln, so that researchers can more intuitively view and analyze the operating status data of different areas in the rotary kiln, study the changing laws of material composition in different areas of the rotary kiln under different operating conditions, explore the optimal operating conditions of the rotary kiln, improve production efficiency, reduce energy consumption, and ensure product quality.
