Description

Technical Field

[0001] This invention relates to the field of petroleum coke proportioning technology, and in particular to a petroleum coke proportioning and addition control system. Background Technology

[0002] In the energy and chemical industries, petroleum coke blending is a crucial production step. As a byproduct of oil refining, petroleum coke is characterized by high carbon content and low ash content, and is widely used as fuel or raw material in industries such as aluminum electrolysis, cement, and steel. Different industries have varying quality requirements for petroleum coke, and petroleum coke from a single source often cannot fully meet production demands. Therefore, the scientific blending of petroleum coke of different qualities and sources to obtain mixed petroleum coke products that meet specific requirements has become an important means to improve resource utilization, reduce production costs, and meet market demands.

[0003] In traditional petroleum coke blending processes, proportion calculations rely primarily on manual experience or simple table lookups. Because petroleum coke quality indicators (such as sulfur content, volatile matter, and ash content) fluctuate, and different batches of petroleum coke exhibit significant differences in characteristics, manual calculations are insufficient to accurately adjust to real-time changes in raw material properties. Furthermore, in terms of flow control, traditional equipment often employs mechanical flow regulators, which have limited adjustment precision and cannot achieve high-precision flow control. This leads to deviations between the actual blending ratio and the theoretical ratio, resulting in unstable quality of the blended petroleum coke and failing to meet the stringent quality consistency requirements of downstream industries.

[0004] In traditional petroleum coke blending operations, manual labor dominates. From weighing and handling raw materials to adding them, a large amount of manpower is required. This is not only labor-intensive but also slow, resulting in a lengthy blending process. Furthermore, manual operation is prone to errors, such as incorrect weighing or incorrect order of addition. Once a problem is discovered, adjustments must be made, further extending the production cycle and reducing production efficiency.

[0005] The lack of an effective real-time monitoring and early warning mechanism is a major drawback of traditional petroleum coke blending technology. During the blending process, it is impossible to monitor the proportion of petroleum coke and the flow rate changes of each raw material in the mixing unit in real time. Once a proportioning error or flow abnormality occurs, it cannot be detected and adjusted in time, which can easily lead to quality problems or even production accidents. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes a petroleum coke proportioning and addition control system, which more accurately solves the problems mentioned in the background art.

[0007] This invention is achieved through the following technical solution: This invention proposes a petroleum coke proportioning and addition control system, comprising: a raw material storage unit for storing different types of petroleum coke raw materials; a proportioning calculation unit for calculating the required addition amount of various petroleum coke raw materials according to a preset proportioning scheme and production requirements; a conveying control unit for controlling the flow rate of petroleum coke raw materials conveyed from each raw material storage unit to the mixing device according to the calculation results of the proportioning calculation unit; a mixing device for uniformly mixing the various petroleum coke raw materials conveyed; and a monitoring and feedback unit for real-time monitoring of the petroleum coke proportioning in the mixing device and feeding back the monitoring data to the proportioning calculation unit so as to adjust the conveying flow rate of the conveying control unit.

[0008] Preferably, the raw material storage unit includes multiple independent storage bins, each of which is used to store a specific type of petroleum coke raw material, and each storage bin is equipped with a flow regulating valve.

[0009] Preferably, the proportioning calculation unit includes: a data input module for receiving a preset proportioning scheme and production demand data; a calculation module for calculating the required amount of various petroleum coke raw materials to be added based on the data received by the data input module; and a data output module for outputting the calculation results to the conveying control unit.

[0010] Preferably, the conveying control unit includes: a flow control module, which generates flow control commands for each raw material storage unit based on the calculation results of the proportioning calculation unit; and an execution module, which receives the flow control commands. It also controls the flow regulating valves of each raw material storage unit to regulate the conveying flow of petroleum coke raw materials.

[0011] Preferably, the mixing device includes: a mixing chamber for receiving and mixing various petroleum coke raw materials; and a stirring mechanism disposed in the mixing chamber for stirring the petroleum coke raw materials to achieve uniform mixing.

[0012] Preferably, the monitoring and feedback unit includes: a proportioning monitoring module for real-time monitoring of the proportion of petroleum coke in the mixing unit; and a data feedback module for feeding back the monitoring data to the proportioning calculation unit for proportioning calculation. The calculation unit adjusts the conveying flow rate of the conveying control unit based on the monitoring data.

[0013] Preferably, the proportioning monitoring module uses an online analytical instrument to analyze the chemical composition or physical properties of petroleum coke in the mixing unit in real time to determine its proportioning.

[0014] Preferably, it also includes an alarm unit, which issues an alarm signal when the monitoring and feedback unit detects that the proportion of petroleum coke in the mixing unit exceeds a preset range.

[0015] Preferably, it also includes a data recording and storage unit for recording and storing proportioning data, conveying flow data and monitoring data during the production process, so as to facilitate subsequent analysis and traceability.

[0016] Preferably, it also includes a remote monitoring and operation unit, which is connected to the control system through a communication network to realize the functions of remotely monitoring the production process and remotely operating the control system.

[0017] Compared with the prior art, the present invention provides a petroleum coke proportioning and addition control system, which has the following beneficial effects: This petroleum coke blending and control system ensures accurate proportioning and uniform mixing of petroleum coke raw materials through precise calculations and flow control, thereby improving the uniformity and stability of the final product. Simultaneously, the automated control system reduces manual operation time and errors, significantly improving production efficiency and enabling enterprises to respond more quickly to market demands, thus enhancing their competitiveness.

[0018] This petroleum coke blending and control system integrates a monitoring and feedback unit as well as an alarm. The unit can monitor the proportion of petroleum coke in the mixing unit in real time and immediately issue an alarm when the proportion exceeds the preset range. This real-time monitoring and early warning mechanism effectively avoids quality problems or production accidents that may be caused by proportioning errors, greatly enhances the safety and controllability of the production process, and ensures the safety of personnel and equipment.

[0019] This petroleum coke blending and control system, through the introduction of data recording and storage units as well as remote monitoring and operation units, enables the complete recording and long-term preservation of key data during the production process. This data not only provides strong support for optimizing the production process but also supports management in data analysis and decision-making. Through remote monitoring, managers can grasp production dynamics anytime, anywhere, adjust production strategies promptly, and improve management efficiency and the scientific basis of decision-making. Simultaneously, the data traceability function facilitates the investigation and resolution of product quality issues. Attached Figure Description

[0020] Figure 1 is a schematic diagram of the process of a petroleum coke proportioning and addition control system proposed in this invention. Detailed Implementation

[0021] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example

[0022] As shown in Figure 1, the petroleum coke proportioning and addition control system proposed in one embodiment of the present invention mainly consists of a raw material storage unit, a proportioning calculation unit, a conveying control unit, a mixing device, and a monitoring and feedback unit. The raw material storage unit has multiple independent storage bins, each used to store different types of petroleum coke raw materials, such as high-sulfur coke and low-sulfur coke. Each storage bin is equipped with a flow regulating valve to control the output flow rate of the raw materials. The proportioning calculation unit, based on a preset proportioning scheme and production requirements, accurately calculates the required addition amount of various petroleum coke raw materials using its built-in calculation module, and transmits the calculation results to the conveying control unit. The conveying control unit generates corresponding flow control commands based on the received calculation results, controlling the flow regulating valves of each raw material storage unit to precisely control the flow rate of petroleum coke raw materials delivered to the mixing unit. The mixing unit receives petroleum coke raw materials from each raw material storage unit and mixes them uniformly through a stirring mechanism to ensure thorough blending of various raw materials. The monitoring and feedback unit monitors the proportion of petroleum coke in the mixing unit in real time, analyzes its chemical composition or physical properties using online analytical instruments, and feeds the monitoring data back to the proportioning calculation unit so that the conveying control unit can adjust the conveying flow rate in a timely manner to ensure proportioning accuracy. This achieves precise proportioning and uniform mixing of petroleum coke raw materials, improving product quality and production efficiency.

[0023] In this invention, the raw material storage unit is designed with multiple independent storage bins, each with a sealed structure to prevent the raw materials from getting damp and contaminated. The storage bins are made of wear-resistant and corrosion-resistant alloy steel to ensure that they do not deform or leak during long-term use. Each storage bin is equipped with a flow regulating valve at the bottom. This valve is electrically or pneumatically controlled, with fast response and high adjustment accuracy, ensuring the purity and storage safety of the raw materials, while also achieving precise control of the raw material flow rate.

[0024] In this invention, the proportioning calculation unit consists of a data input module, a calculation module, and a data output module. The data input module provides a user interface, allowing operators to input preset proportioning schemes and production demand data, such as raw material types, proportions, and production volumes. The calculation module uses a high-performance processor to perform rapid and accurate calculations based on the input data, determining the required amounts of various petroleum coke raw materials to be added. The data output module transmits the calculation results to the conveying control unit in the form of digital or analog signals, enabling flexible setting and precise calculation of the proportioning scheme and providing an accurate basis for subsequent conveying control.

[0025] In this invention, the conveying control unit includes a flow control module and an execution module. The flow control module receives calculation results from the proportioning calculation unit and generates flow control commands for each raw material storage unit using a built-in control algorithm. The execution module employs electric or pneumatic actuators to precisely control the opening of the flow regulating valves in each raw material storage unit according to the flow control commands, thereby regulating the conveying flow rate of the petroleum coke raw material. Precise control of raw material conveying flow rate was achieved, ensuring the accuracy of the proportioning.

[0026] In this invention, the mixing device consists of a mixing chamber and a stirring mechanism. The mixing chamber has a cylindrical structure with a smooth interior and no dead corners, facilitating the flow and mixing of raw materials. The stirring mechanism is installed at the center of the mixing chamber and employs a multi-layered blade design. Driven by a motor, it rotates at high speed to thoroughly stir and mix the petroleum coke raw material entering the mixing chamber, achieving uniform mixing of the petroleum coke raw material and improving the uniformity and stability of the product.

[0027] In this invention, the monitoring and feedback unit consists of a proportioning monitoring module and a data feedback module. The proportioning monitoring module uses online analytical instruments, such as infrared spectrometers and X-ray fluorescence spectrometers, to analyze the chemical composition or physical properties of the petroleum coke in the mixing unit in real time to determine its proportions. The data feedback module transmits the monitoring data to the proportioning calculation unit via a communication interface, allowing the proportioning calculation unit to adjust the conveying flow rate of the conveying control unit in a timely manner based on the monitoring data. This achieves real-time monitoring and feedback adjustment of the petroleum coke proportions in the mixing unit, ensuring the continuous accuracy and stability of the proportions.

[0028] In this invention, the online analytical instrument selected for the proportioning monitoring module features high precision, high stability, and rapid response. The instrument performs real-time analysis of petroleum coke within the mixing unit using a non-contact measurement method, obtaining accurate chemical composition or physical property data without the need for sampling. The instrument is also equipped with automatic calibration and fault diagnosis functions, ensuring long-term accuracy and reliability, improving the accuracy and efficiency of proportioning monitoring, and reducing the cost and time associated with manual sampling and testing.

[0029] In this invention, the alarm unit employs audible and visual alarms or SMS alarms. When the monitoring and feedback unit detects that the proportion of petroleum coke in the mixing unit exceeds the preset range, an alarm signal is immediately triggered. The alarm signal can be displayed intuitively on the operating interface and relevant personnel can be notified promptly via sound or SMS, improving the safety and controllability of the production process and avoiding quality problems or production accidents caused by proportioning errors.

[0030] In this invention, the data recording and storage unit employs a high-performance industrial computer or data logger to record and store key information such as proportioning data, conveying flow data, and monitoring data during the production process in real time. Data recording can be performed in database or file format, facilitating subsequent analysis and traceability. Simultaneously, the unit is equipped with data backup and recovery functions to ensure data security and integrity, providing strong data support for production process optimization and quality control.

[0031] In this invention, the remote monitoring and operation unit is connected to the control system via a communication network (such as Ethernet, wireless network, etc.) to achieve the functions of remotely monitoring the production process and remotely operating the control system. Operators can log in to the control system interface through remote terminal devices (such as computers, mobile phones, etc.) to view production data and equipment status in real time, and perform remote control and adjustments. Simultaneously, this unit is also equipped with security authentication and access control functions to ensure the security and legality of remote operations, improve the flexibility and efficiency of production management, and reduce the labor intensity and safety risks for on-site operators.
