Description

Technical Field

[0001] The present invention relates to the technical field of pipeline monitoring, and in particular to a temperature management system and method for a process pipeline. Background Art

[0002] In the petroleum and petrochemical industry, the medium in the process pipeline needs to be kept within a certain temperature range to prevent freezing and blockage, which may affect the normal operation of the production process. Electric heating is an effective and safe heating method, so it is widely used to heat process pipelines. Electric heating cables are usually wrapped in the insulation layer of the process pipeline, and provide heat to the medium in the pipeline by heating it with electricity to maintain its temperature stable.

[0003] The existing scheme mainly adopts the traditional electric heating cable heating system, which supplies power to the electric heating cable through the power supply to make it heat up, thereby transferring the heat to the medium in the process pipeline. In terms of control, a simple temperature control device is generally used, such as a temperature controller, which automatically controls the power on and off of the electric heating cable according to the set temperature range to maintain the pipeline temperature within the appropriate range.

[0004] However, the traditional electric heating system has the following technical disadvantages:

[0005] (1) Fault detection is difficult

[0006] Since the electric heating cable is wrapped in an insulation layer, its working status is difficult to directly observe and detect. When the electric heating cable fails, such as a break, short circuit, uneven heating, etc. at a certain pipeline node, it is difficult for the staff to find it in time, resulting in a long fault response cycle and failure to handle the fault in time. Even in actual production, due to untimely troubleshooting, the medium may freeze and cause pipeline blockage, equipment damage and other problems, seriously affecting production efficiency and safety.

[0007] (2) Manual detection methods are backward

[0008] At present, whether the electric heating belt is working properly mainly depends on manual on-site inspection, which is a fuzzy investigation. The staff needs to regularly go to the site to use detection equipment (such as thermometers, etc.) to measure the temperature of the electric heating belt, and then judge its working status based on experience. This method is not only inefficient, but also has limited accuracy. Manual inspection cannot grasp the working status of the electric heating belt in real time, and cannot detect potential problems in time. At the same time, the labor cost is also high, and in some harsh working environments (such as high temperature, high pressure, toxic and harmful places), manual inspection still has certain safety risks.

[0009] (3) Data transmission is not real-time

[0010] Existing technologies cannot transmit the working data of electric heating cables in real time. This makes it impossible for managers to understand the operating status of the electric heating system in a timely manner, and it is impossible to conduct remote monitoring and data analysis. When abnormal situations occur, effective measures cannot be taken in time to deal with them. For example, when the temperature of the process pipeline fluctuates abnormally, due to the lack of real-time data transmission, managers may not be able to find the problem in time, resulting in an increased probability of production accidents. Summary of the invention

[0011] 1. Technical issues to be resolved

[0059] Figure 2 The present invention is a flowchart of a method for temperature management of a process pipeline according to an embodiment of the present invention. DETAILED DESCRIPTION

[0060] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0061] refer to Figure 1 As shown, a temperature management system for a process pipeline proposed in an embodiment of the present invention includes: a pipeline heating module, which is arranged on the process pipeline and is used to obtain temperature data of the process pipeline and heat the process pipeline through the set electric heating tape; a regional monitoring module, which is connected to the pipeline heating module and is used to provide target electric energy to the electric heating tape in the corresponding area and receive temperature data of each section of the process pipeline; and is also used to monitor the target electric energy and send the electric energy monitoring data and temperature data to the enterprise management center; the enterprise management center is connected to the regional monitoring module and is used to receive monitoring signals of each regional monitoring module, and cooperates with a preset pipeline inspection system to perform closed-loop management including real-time response to temperature alarms, analysis and processing, and transmitting the generated electric heating tape control signal back to the corresponding regional monitoring module.

[0062] This embodiment adopts a three-layer temperature management system architecture. The first layer is a pipeline heating module, which is deployed on the process pipeline to obtain the pipeline temperature and heat the pipeline through the set electric heating tape; the second layer is a regional monitoring module, which is used to monitor the power supply of the electric heating tape, and receive and integrate the monitoring data and pipeline temperature data; the third layer is an enterprise management center, which receives the monitoring signals of each regional monitoring module, and cooperates with the pipeline inspection system to perform closed-loop management including real-time response to temperature alarms, analysis and processing, and transmitting the generated electric heating tape control signal back to the corresponding regional monitoring module.

At the same time, after analyzing and processing the monitoring signal through the enterprise management center, it can also generate the electric heating tape control signal, control the operation of the electric heating tape in real time, and coordinate the monitoring signal through the pipeline inspection system, so that the management system can respond to the temperature alarm of the pipeline in real time.

[0063] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0064] First, the pipeline heating module is equipped with: electric heating tape and temperature detection terminal. The electric heating tape is arranged on the process pipeline, and the electric heating tape is used to heat the process pipeline to keep the conveying medium in the process pipeline within the set temperature range. The temperature detection terminal is evenly arranged on the process pipeline, and the temperature detection terminal is used to send the collected temperature data of the process pipeline to the regional monitoring module and receive the temperature alarm information sent back by the regional monitoring module.

[0065] Furthermore, the temperature detection terminal includes a temperature sensor, a wireless communication chip and an alarm. The temperature sensor is used to collect temperature data of the process pipeline; the wireless communication chip is connected to the temperature sensor, and is used to send the collected temperature data to the regional monitoring module and receive the temperature alarm information sent back by the regional monitoring module; the alarm is connected to the wireless communication chip, and is used to activate the alarm when receiving the temperature alarm information from the regional monitoring module. Among them, the wireless communication chip is any one of the communication chips among the LoRaWAN chip, the NB-IoT chip and the 5G chip.

[0066] In this embodiment, the deployment distance of each electric heating cable is 50 to 100 meters. After the electric heating cable is deployed to the process pipeline, a temperature detection terminal is installed in the middle of the pipeline. The temperature sensor in the temperature detection terminal can collect temperature data on the surface of the process pipeline. The temperature detection range of the temperature sensor is -50°C to 125°C. The alarm in the temperature detection terminal can generate three alarm signals, namely, low report alarm, first high alarm and second high alarm. The low report alarm is activated when the pipeline temperature is lower than the set temperature, the first high alarm is activated when the pipeline temperature is higher than the set temperature, and the second high alarm is activated when the pipeline temperature is higher than the set temperature and the working current or working voltage of the electric heating cable is abnormal.

[0067] It is worth mentioning that the temperature sensor is any one of a thermistor, an infrared temperature sensor and a distributed optical fiber temperature sensor.

[0068] When the temperature sensor is a thermistor, the thermistor is set at a pre-set temperature detection point on the process pipeline, and the thermistor is in contact with the surface of the electric heating cable. For example, when the conveying medium in the process pipeline is a flammable and explosive medium such as petroleum and petrochemical, it is necessary to accurately measure the pipeline temperature to monitor the pipeline temperature in real time. Therefore, a contact temperature sensor is used to measure the pipeline temperature, so that the conveying medium can be transported in a safe pipeline environment while ensuring that the pipeline is not blocked.

[0069] When the temperature sensor is an infrared temperature sensor, the external temperature sensor is set at a pre-set temperature detection point on the process pipeline, and the detection distance between the infrared temperature sensor and the electric heating cable is the set detection distance. For example, for a process pipeline that is installed with an insulation layer and is not convenient to disassemble, the temperature sensor of the temperature detection terminal can be an infrared temperature sensor. The infrared temperature sensor is used to measure the temperature of the electric heating cable from the outside. Although the accuracy may be slightly lower than that of a contact temperature sensor, it can meet the needs of rapid detection of temperature anomalies.

[0070] When the temperature sensor is a distributed optical fiber temperature sensor, the distributed optical fiber temperature sensor is arranged on the process pipeline, and the distributed optical fiber temperature sensor is in contact with the surface of the electric heating cable. For example, on a long process pipeline, the distributed optical fiber temperature sensor can monitor the temperature change of the entire pipeline in real time, provide more comprehensive temperature distribution information, enable maintenance personnel to timely find the local overheating or overcooling pipeline area, and then provide maintenance personnel with more detailed fault information.

[0071] Secondly, the regional monitoring module is equipped with: current sensor, voltage sensor and electronic switch. The current sensor is used to collect the current information of the target electric energy. The voltage sensor is used to collect the voltage information of the target electric energy. The electronic switch is used to turn on or off the power supply of the electric heating belt when receiving the electric heating belt control signal sent back by the enterprise management center.

[0072] In a specific embodiment, the area monitoring module can be regarded as an electric heating monitoring host, which provides 220V / 20A power for two electric heating cables, and a current sensor and a voltage sensor are set at each output end to monitor the current and voltage of the two electric heating cables. The electronic switch in the electric heating monitoring host is set at the input end of the 220V / 20A power, and can disconnect the switch when the current and voltage of the electric heating cable are abnormal, so as to stop the power supply to the electric heating cable. The electronic switch can use an intelligent circuit breaker with functions such as remote control, automatic protection, and fault diagnosis to achieve faster and more accurate power cut-off. When a short circuit or other fault is detected in the electric heating cable, the intelligent circuit breaker can immediately cut off the power supply and send fault information at the same time so that maintenance personnel can handle it in time.

[0073] In another specific embodiment, a programmable logic controller (PLC) or a microcontroller may be used instead of the electronic switch. When the controller receives the electric heating tape control signal sent back by the enterprise management center, the power supply of the electric heating tape is quickly cut off. The power cut-off has the advantages of high flexibility and low cost, and can also be customized according to different application scenarios.

[0074] Finally, the enterprise management center is equipped with: gateway server and unified construction system. The gateway server is used to upload the monitoring signals of each regional monitoring module to the temperature management system. The unified construction system includes a pipeline temperature management system and a pipeline inspection system, which is used to analyze and process the monitoring signals through the temperature management system, and respond to temperature alarms in real time based on the processing results and the feedback electric heating belt control signal in combination with the pipeline inspection system; and, the electric heating belt control signal and / or the real-time response temperature alarm signal are also transmitted back to the corresponding regional monitoring module through the gateway server.

[0075] In a specific embodiment, the gateway server uses a LoRa gateway, and the LoRa gateway supports access to 16 electric heating monitoring hosts. The LoRa gateway uploads the monitoring signals of each electric heating monitoring host to the unified system. The temperature management system in the unified system analyzes and processes the monitoring signals, and based on the processing results and the feedback electric heating belt control signal, when the processing results contain temperature alarm information, the pipeline inspection system is called to perform collaborative processing on the temperature alarm information and respond to the temperature alarm in real time. Then, the unified system transmits the electric heating belt control signal and the response temperature alarm signal back to the corresponding electric heating monitoring host. Finally, the electric heating monitoring host controls the power supply of the electric heating belt, and at the same time sends the temperature alarm signal to the corresponding temperature detection terminal, so that the temperature detection terminal executes the corresponding level of temperature alarm.

[0076] Further explanation: the temperature management system analyzes and processes the monitoring signal, including: when the temperature data in the monitoring signal is lower than the set temperature range, the control signal of turning on the electric heating belt and starting the low alarm is fed back; when the temperature data in the monitoring signal is within the set temperature range and the voltage and current of the target electric energy are within the set threshold range, the control signal of turning on the electric heating belt and turning off the low alarm is fed back; when the temperature data in the monitoring signal is higher than the set temperature range or the voltage and current of the target electric energy are not within the set threshold range, the control signal of turning off the electric heating belt and starting the first high alarm is fed back; when the temperature data in the monitoring signal is higher than the set temperature range and the voltage and current of the target electric energy are not within the set threshold range, the control signal of turning off the electric heating belt and starting the second high alarm is fed back. Among them, the temperature range is set to 5 levels, namely 15℃~105℃, 15℃~90℃, 15℃~85℃, 15℃~80℃, 15℃~65℃. The staff can select the appropriate temperature range to detect the pipeline temperature according to the needs of the process pipeline.

[0077] On the other hand, reference Figure 2 As shown, this embodiment also provides a temperature management method for a process pipeline, which is applied to the temperature management system of the process pipeline described above, and the method includes:

[0078] S1. Obtain the temperature information of the process pipeline surface through the pipeline heating module.

[0079] S2. Obtain the current and voltage information of the electric heating tape through the area monitoring module.

[0080] S3. Analyze and process the temperature information and the current and voltage information to generate an electric heating tape control signal and a temperature alarm signal.

[0081] S4. Sending the electric heating tape control signal to the area monitoring module to disconnect or start the power supply of the electric heating tape in the area monitoring module.

[0082] S5. After the temperature alarm signal is handed over to the pipeline inspection system for collaborative processing, the processed signal is sent to the regional monitoring module, so that the process pipeline area with abnormal temperature can respond to the temperature alarm in real time.

[0083] Furthermore, step S3 may include the following sub-steps:

[0084] S31. Determine whether the temperature of the process pipeline surface is within a set temperature range.

[0085] S32a. When the temperature of the process pipeline surface is lower than the set temperature range, the control signal to turn on the electric heating tape and initiate the low reporting alarm is fed back.

[0086] S32b. When the temperature of the process pipeline surface is within the set temperature range or higher than the set temperature range, it is determined that the voltage and current of the electric heating tape are within the set threshold range.

[0087] S33a. When the temperature of the process pipeline surface is within the set temperature range and the voltage and current of the electric heating tape are within the set threshold range, a control signal for turning on the electric heating tape and turning off the low-report alarm is fed back.

[0088] S33b. When the temperature of the process pipeline surface is higher than the set temperature range or the voltage and current of the electric heating tape are not within the set threshold range, a control signal is fed back to shut down the electric heating tape and start the first high alarm.

[0089] S33c. When the temperature of the process pipeline surface is higher than the set temperature range and the voltage and current of the electric heating tape are not within the set threshold range, a control signal is fed back to shut down the electric heating tape and start the second highest reporting alarm.

[0090] In summary, the temperature management system and method of a process pipeline proposed in the embodiment of the present invention can be operated as follows: first, the temperature of the electric heating belt or the process pipeline is detected by the temperature detection terminal, and the temperature data is transmitted to the regional monitoring module (electric heating monitoring host) through wireless communication technology. Secondly, the regional monitoring module monitors the voltage and current of the electric heating belt, and sends the monitoring data and temperature data to the enterprise management center. Then, after receiving the monitoring data and temperature data of each regional monitoring module, the enterprise management center cooperates with the preset pipeline inspection system to perform closed-loop management including real-time response to temperature alarms, analysis and processing, and returning the generated electric heating belt control signal to the corresponding regional monitoring module. Finally, the regional monitoring module controls the power supply of the electric heating belt and sends the temperature alarm signal to the corresponding temperature detection terminal at the same time, so that the temperature detection terminal executes the temperature alarm of the corresponding level. The present invention can remotely monitor and manage the temperature of the process pipeline in real time, and after analyzing and processing the monitoring signal by the enterprise management center, it can also send the electric heating belt control signal, control the operation of the electric heating belt in real time, and coordinate the monitoring signal through the pipeline inspection system, so that the management system can respond to the temperature alarm of the pipeline in real time.
