Description

Technical Field

[0001] This invention relates to the field of petrochemical technology, and in particular to an intelligent monitoring and automatic control system for coke level under saturated steam environment. Background Technology

[0002] In delayed coking units, the coke tower needs to be decoked once a day. Based on a unit with a capacity of 1 million tons / year, about 1,000 tons of coke can be produced per day. During the coke discharge process, a large amount of water, water vapor and coke particles are carried. Especially after the modification of the closed decoking system, water vapor cannot diffuse quickly and accumulates in large quantities inside the closed box, which seriously obstructs the operator's line of sight and the monitoring field of high-definition video monitoring, making it impossible to accurately judge the coke level and flow status.

[0003] However, during the coking process, due to the pervasive steam in the dehydration chamber, operators have difficulty observing the material discharge from the bottom chute of the coke tower, making it impossible to adjust the coking operation in time. This can easily lead to accidents such as coke collapse, chute blockage, and overflow of water from the dehydration chamber. The crusher frequently trips due to coke blockage during operation, causing system shutdowns. Operators need to spend a lot of time dealing with the blockage problem, which not only affects production efficiency, but also traditional monitoring methods can mostly only monitor a single parameter, making it difficult to capture the coke cutting status, coke morphology, material level, and water level in all dimensions. They lack effective risk prediction and automatic control mechanisms, rely on manual intervention, and are slow and unsafe. Summary of the Invention

[0004] In view of this, the present invention provides an intelligent monitoring and automatic control system for coke level in a saturated water vapor environment. It employs a dual monitoring mode combining a lidar level gauge and infrared thermal imaging monitoring, along with image recognition algorithms and a multi-parameter fusion calculation model. This system can effectively penetrate the saturated water vapor barrier inside a sealed chamber, unaffected by water vapor accumulation or floating coke particles. It solves the problem of traditional high-definition video monitoring and manual observation being unable to accurately determine coke level and flow status due to obstructed views. It can accurately collect level and water level data in real time, with errors controlled within a reasonable range. The monitoring camera oscillates back and forth, significantly expanding the monitoring coverage area and simultaneously capturing the three-dimensional morphology, flow velocity, and bulk density of coke. This achieves full-dimensional capture of coke level, water level, flow status, and coke morphology, breaking through the limitations of traditional single-parameter monitoring and providing comprehensive and reliable data support for subsequent control decisions.

[0014] Beneficial effects:

[0015] This invention innovatively employs a dual-monitoring mode combining lidar level gauges and infrared thermal imaging monitoring. By integrating image recognition algorithms with a multi-parameter fusion calculation model, it can effectively penetrate the saturated water vapor barrier inside a sealed chamber, unaffected by water vapor accumulation or floating coke particles. This solves the problem of traditional high-definition video monitoring and manual observation being unable to accurately determine coke level and flow status due to obstructed views. It can accurately collect real-time data on coke level and water level with errors controlled within a reasonable range. The reciprocating movement of the monitoring camera significantly expands the monitoring coverage, simultaneously capturing the three-dimensional morphology, flow velocity, and bulk density of coke. This achieves full-dimensional capture of coke level, water level, flow status, and coke morphology, breaking through the limitations of traditional single-parameter monitoring and providing comprehensive and reliable data support for subsequent control and decision-making.

[0016] In use, this invention utilizes the data processing and risk analysis module within the data transmission module to perform real-time analysis and fusion calculations on the collected multi-dimensional data. Combined with the enhanced early warning and control unit, it enables advance prediction and tiered early warning of risks. Through audible and visual alarms and pop-up prompts on the control interface, operators are promptly alerted to potential risks. Simultaneously, relying on the PLC control module, an automatic control closed loop is constructed. When the system predicts risks such as coke blockage, coke collapse, or overflow of water level in the dehydration chamber, it can automatically generate targeted control commands, synchronously controlling the water pressure adjustment of the coke cutter, the frequency adaptation of the crusher, the optimization of the intelligent grab mechanism's operating path, and the adjustment of the cooling rhythm of the cold coke water circulation system. This allows for rapid response and risk management without manual intervention. The feedback monitoring unit collects real-time equipment operation data and coke status data after control measures, transmitting them back to the data processing module for secondary evaluation until the risk is eliminated. This completely solves the safety hazards caused by the lag and large operational errors of traditional manual control, achieving full-process automation of "monitoring-analysis-early warning-control-feedback," significantly improving the safety and stability of system operation.

[0017] This invention effectively solves the problems of coke residue and secondary blockage through a specially designed intelligent grab mechanism. The intelligent grab mechanism relies on hydraulic push rods for vertical lifting and lowering, and electric push rods drive the grab bucket to open and close to grab coke. At the same time, it is equipped with a vibration cleaning structure consisting of a drive worm gear, drive worm, and transmission cam, which can drive the grab bucket to vibrate at high frequency, completely shaking off the coke adhering to the grab bucket, preventing residual coke from falling into the chute and feed inlet and forming secondary accumulation and blockage, thus reducing the frequency of crusher shutdown due to coke blockage. In addition, the system automatically controls the coordinated rhythm of coke cutting, crushing, and grab bucket operations to avoid system downtime caused by improper manual operation, shortening downtime processing time. It is especially suitable for the continuous coking needs of large-scale delayed coking units such as 1 million tons / year, which can effectively improve the daily coking efficiency, reduce the workload of manual handling of coke blockage and cleaning residue, reduce labor costs, and significantly improve overall production efficiency.

[0018] All actuators in this invention employ precise automatic control, avoiding problems such as equipment overload and misoperation that may occur during manual operation. This reduces equipment wear and lowers the failure rate. For example, the vibration-based coke removal function of the intelligent grab bucket mechanism reduces coke adhesion and wear on the inner wall of the grab bucket, extending its service life. The adaptive adjustment of the crusher frequency prevents damage caused by overload operation. The coordinated control of the cold coke water circulation system optimizes the equipment operating environment, reducing the rate of equipment corrosion and aging. Simultaneously, the automated operation of the system significantly reduces the workload of manual inspection, operation, and maintenance, lowering labor and maintenance costs and improving the economy and sustainability of the entire delayed coking unit's decoking operation.

[0019] The modular design of this invention is tailored to the actual operating conditions of a closed decoking system. The swing structure for infrared thermal imaging monitoring and the movable and vibratory decoking structure of the intelligent grab mechanism can flexibly adapt to the installation and operation requirements of dehydration chambers of different sizes. The system's multi-parameter fusion monitoring and automatic control logic can flexibly adjust monitoring thresholds and control parameters according to the decoking capacity and coke characteristics of delayed coking units of different scales, demonstrating strong adaptability. In addition, the system can directly connect to the decoking system of existing delayed coking units without large-scale equipment modifications. The modification is simple and cost-effective, facilitating the upgrading and iteration of existing units. It can be widely applied to closed decoking operations in various delayed coking units in the petrochemical field, possessing extremely high promotional value and application prospects.

The lidar level gauge 2 is fixedly connected to the top end face inside the dewatering chamber 1. A feed inlet 101 is opened on the right end face of the dewatering chamber 1. The infrared thermal imaging monitoring system 3 is set at... On the opposite side of the feed inlet 101; the infrared thermal imaging monitoring 3 is fixedly connected to the dehydration chamber 1 via the mounting bracket 301; the equipment execution module 602 is connected to the data transmission module 601; the equipment execution module 602 includes an intelligent grab mechanism; the intelligent grab mechanism is located at the top of the inner side of the dehydration chamber 1; an electric slide rail 102 is provided on the top end face of the inner side of the dehydration chamber 1; the intelligent grab mechanism includes: a hydraulic push rod 4, which is fixedly connected to the electric slider 103 of the electric slide rail 102 via multiple bolts and connecting flanges; the electric slider 103 is slidably connected to the electric slide rail 102.

[0037] The enhanced early warning and control system includes a risk warning module and a PLC control module; the risk warning module provides risk warnings based on the collected data; and the PLC control module controls and regulates the data.

[0038] The equipment execution module 602 includes a coke cutter, a crusher, an intelligent grab bucket mechanism, a feedback monitoring unit, and a cold coke water circulation system. The equipment execution module 602 controls and executes the operating status of the coke cutter, the crusher, the intelligent grab bucket mechanism, the feedback monitoring unit, and the cold coke water circulation system, and performs related operations.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When in use, the sealed coke removal system is activated, and the infrared thermal imaging monitoring 3 and the lidar level gauge 2 of the data acquisition module 6 are simultaneously turned on. After the equipment completes its self-test, it enters a continuous data acquisition state. The data transmission module 601 transmits the acquired image data, material level data, and water level data to the data processing and risk analysis module through an anti-interference line. The image recognition algorithm analyzes the three-dimensional morphology, flow velocity, and bulk density of the coke. The multi-parameter fusion calculation model, combined with the material level and water level data, determines the current operating status and risk level. If the system is determined to be in a risk-free state, it maintains the current coke cutting water pressure, crusher frequency, and intelligent grab bucket mechanism operating parameters. Block 6 continuously monitors; if a risk of coke blockage, coke collapse, or water overflow is detected, enhanced early warning and control immediately issues an audible and visual alarm and a pop-up notification on the control interface, and the PLC control system simultaneously generates targeted control commands; the equipment execution module 602 receives the control commands, and the coke cutter adjusts the water pressure, the crusher's adaptation frequency, the intelligent grab bucket mechanism's operating path, and the unloading rhythm, while the cold coke water circulation system coordinates to adjust the cooling rhythm; the feedback monitoring unit collects the equipment operation data, coke status data, and material or water level data after control, and transmits them back to the data processing and risk analysis module for secondary evaluation; if the data meets the safety threshold, the system resumes normal monitoring; if the risk is not eliminated, the PLC... The control system generates enhanced control commands, and the equipment execution module 602 receives the control commands again. The coke cutter adjusts the water pressure, the crusher's adaptive frequency, the intelligent grab bucket mechanism's operating path, and the unloading rhythm. The cold coke water circulation system coordinates and adjusts the cooling rhythm. The feedback monitoring unit collects the adjusted equipment operation data, coke status data, and material or water level data, and sends them back to the data processing and risk analysis module and the risk analysis layer for re-evaluation until the system is running stably. The data processing and risk analysis module monitors the coke flow status data collected by infrared thermal imaging to determine whether there is a risk of coke blockage in the crusher. If coke blockage exists, the PLC control system adjusts the crusher frequency through the equipment execution module to prevent the equipment from stopping. The cold coke water circulation system adjusts the cooling water volume and cooling rhythm by the PLC control system based on the coke temperature and equipment operating temperature data output by the data processing and risk analysis module, achieving coordinated control.

[0045] Among them, the top end face of the drive shaft 302 is coaxially fixedly connected to the drive gear 305; the bottom end face of the drive shaft 302 is coaxially fixedly connected to the shaft of the geared motor; the lower end of the transmission auxiliary shaft 304 is coaxially fixedly connected to the incomplete gear 306; the incomplete gear 306 meshes with the drive gear 305; and a spiral spring 307 is fixedly connected between the transmission auxiliary shaft 304 and the infrared thermal imaging monitoring 3.

[0046] The intelligent grab mechanism also includes: a positioning bracket 5, an electric push rod 501, a movable bracket 502, a transmission grab frame 504, and a material grab bucket 505; the electric push rod 501 is fixedly connected to the piston rod 401 at the lower end of the hydraulic push rod 4; the movable bracket 502 is fixedly connected to the movable rod 503 at the lower end of the electric push rod 501; there are two transmission grab frames 504, which are symmetrically arranged and hinged to the electric push rod 501; there are two material grab buckets 505, which are symmetrically arranged, and the two ends of the material grab buckets 505 are hinged to the transmission grab frame 504 and the movable bracket 502, respectively.

[0047] The intelligent grab mechanism also includes: a positioning guide 5001, a limiting guide block 5002, and a transmission cam 5004. The positioning guide 5001 is coaxially and fixedly connected to the top end face of the electric push rod 501. The limiting guide block 5002 is fixedly connected to the top end face of the positioning guide 5001 and is elastically connected to the positioning bracket 5 through multiple reset elastic elements 5003. The transmission cam 5004 is rotatably connected to the inner end of the positioning bracket 5, and the outer side of the transmission cam 5004 is pressed against the limiting guide block 5002. The transmission cam 5004 and the limiting guide block 5002 constitute a cam transmission mechanism.

[0048] The intelligent grab mechanism also includes: a drive worm gear 5005 and a drive worm 5006. The drive worm gear 5005 is coaxially and fixedly connected to the transmission cam 5004. The drive worm 5006 is rotatably connected to the positioning bracket 5, and the drive worm 5006 and the drive worm gear 5005 are mutually adapted. The drive worm 5006 and the drive worm gear 5005 together constitute a worm gear transmission mechanism. The outer end of the drive worm 5006 is coaxially and fixedly connected to the rotating shaft of the drive motor.

[0049] The specific usage and function of this embodiment are as follows:

[0050] In use, when the geared motor drives the shaft 302 to rotate, the drive gear 305 drives the incomplete gear 306 and the transmission auxiliary shaft 304 to swing left and right. During the swinging of the transmission auxiliary shaft 304, the monitoring camera 303 swings synchronously. The spiral spring 307 achieves the reset traction of the transmission auxiliary shaft 304. The swinging of the monitoring camera 303 increases the monitoring range. When the hydraulic push rod 4 is activated, the piston rod 401 slides up and down, realizing the up and down sliding of the positioning bracket 5. When the electric push rod 501 is activated, the movable rod 503 slides up and down, and the movable bracket 502 and the transmission grab 504 drive the material grab bucket 505 to flip inward or outward simultaneously, realizing the grabbing operation of coke. When the drive motor drives the worm gear 5006 to rotate, the drive worm wheel 5005 drives the transmission cam 5004 to rotate synchronously. During the rotation of the transmission cam 5004, the limiting guide block 5002 is pushed to slide back and forth within the positioning bracket 5. During the sliding of the limiting guide block 5002, the material grab bucket 505 is driven to vibrate at high frequency, shaking off the coke adhering to the material grab bucket 505. This prevents residual coke from falling into the chute opening and around the coke inlet when the material grab bucket 505 falls back, forming secondary accumulation or blockage, reducing the subsequent cleaning workload, and ensuring that the material grab bucket 505 is clean, maintaining the grab bucket's designed grab capacity, and adapting to the rhythm requirements of continuous coking in the system. The full-range image data collected by the infrared thermal imaging monitoring 3 is transmitted to the data processing and risk analysis module through the data acquisition module 6. The vibration coking action of the intelligent grab bucket mechanism is automatically controlled by the PLC control system to start the drive motor based on the grab bucket residual data collected by the feedback monitoring unit, realizing linkage with the overall control system.
