Description

Technical Field

[0001] This application relates to the field of industrial heat transfer medium circulation safety technology, and in particular to heat transfer oil circulation safety assurance equipment based on multi-parameter monitoring. Background Technology

[0002] Heat transfer oil, also known as thermal oil, is a special industrial oil product belonging to the category of organic heat carriers. This oil achieves indirect heat transfer through liquid or gas phase circulation, and features uniform heating, good thermal stability, low vapor pressure and high temperature operation, resistance to thermal cracking and chemical oxidation, high heat transfer efficiency, and rapid heat dissipation.

[0003] Key parameters such as oil quality, flow state, and system pressure during the heat transfer oil circulation process need to be monitored in real time. In traditional heat transfer oil circulation systems, the heat transfer oil is in a high-temperature circulation state for a long time, which is prone to oxidation and cracking, resulting in increased viscosity and carbon residue. Deteriorated oil has reduced heat transfer efficiency, and carbon residue is easy to deposit and block pipelines. Traditional systems do not have dedicated monitoring equipment and can only rely on periodic sampling and testing, which cannot grasp the oil status in real time and make it difficult to ensure the safe and stable operation of the circulation system. Utility Model Content

[0004] The purpose of this invention is to provide a safety assurance device for heat transfer oil circulation based on multi-parameter monitoring, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-parameter monitoring-based heat transfer oil circulation safety assurance device includes a support base. A circulation pump body is fixedly mounted on the upper surface of the support base via a mounting bracket. An oil inlet pipe is fixedly connected to the input end of the circulation pump body. A pad is fixedly connected to the upper surface of the support base. A control cabinet is mounted on the upper surface of the pad. An audible and visual alarm is mounted on the top of the control cabinet. An oil discharge pipe is fixedly connected to the output end of the circulation pump body. A filter assembly is fixedly connected to one end of the oil discharge pipe. An oil guide pipe is fixedly connected to one side of the filter assembly. A sensor assembly is mounted on the outer surface of the oil guide pipe. The sensor assembly includes a viscosity sensor and a residual carbon monitoring sensor for monitoring oil quality, and a pressure sensor and a flow sensor for monitoring flow state. The filter assembly includes a filter cylinder, and a filter screen is installed inside the filter cylinder.

[0006] As a further embodiment of this invention: the viscosity sensor and the residual carbon monitoring sensor are both installed on the lower part of the outer surface of the oil guide pipe, and the pressure sensor and the flow sensor are both installed on the upper part of the outer surface of the oil guide pipe.

[0007] As a further improvement of this utility model, an automatic pressure relief valve is also installed on the outer surface of the oil guide pipe, and the automatic pressure relief valve is located in the middle of the outer surface of the oil guide pipe.

[0008] As a further improvement of this utility model: a guide plate is installed on the inner wall of the filter cylinder, and a support foot is installed on the bottom surface of the support base.

[0009] As a further improvement of this utility model: a temperature sensor is installed on the outer surface of the oil guide pipe, and a data display instrument electrically connected to the temperature sensor is installed on the outer surface of the control cabinet.

[0010] As a further improvement of this utility model: the control cabinet is electrically connected to the sensor assembly, the automatic pressure relief valve and the data display instrument via wires. The control cabinet integrates a PLC controller with preset safety thresholds and warning thresholds for various parameters and a data analysis module. A pressure gauge is also installed on the outer surface of the oil guide pipe.

[0011] As a further embodiment of this utility model: a bottom support plate is fixedly connected to the upper surface of the support base, and the upper surface of the bottom support plate is connected to the bottom end of the oil guide pipe and the bottom surface of the filter assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This multi-parameter monitoring-based heat transfer oil circulation safety assurance device collects heat transfer oil quality parameters in real time through a viscosity sensor and a residual carbon monitoring sensor in the sensor assembly. The data is transmitted to the control cabinet for analysis. When the parameters exceed the threshold, an audible and visual alarm immediately issues a warning, avoiding the lag of traditional sampling and testing. Meanwhile, a temperature sensor monitors the oil temperature simultaneously, and combined with the quality parameters, it judges the deterioration trend, providing an accurate basis for oil replacement and reducing safety risks. Furthermore, the filter assembly's filter cartridge has a built-in filter screen and a guide plate. The guide plate guides the heat transfer oil to form a spiral flow, extending the filtration path and improving impurity interception efficiency. The filter screen intercepts mechanical impurities and coking products, preventing pipeline accumulation. This significantly reduces system resistance, lowers the load on the circulation pump, and reduces energy consumption. At the same time, it improves the heat transfer efficiency of the heat exchanger, achieving high-efficiency filtration and drag reduction, and improving system efficiency.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figures 1-4 In this embodiment of the utility model, the heat transfer oil circulation safety assurance device based on multi-parameter monitoring includes a support base 1. A circulation pump body 6 is fixedly mounted on the upper surface of the support base 1 via a mounting bracket 7. An oil inlet pipe 8 is fixedly connected to the input end of the circulation pump body 6. A pad 2 is fixedly connected to the upper surface of the support base 1. A control cabinet 3 is mounted on the upper surface of the pad 2. An audible and visual alarm 4 is mounted on the top of the control cabinet 3. An oil drain pipe 9 is fixedly connected to the output end of the circulation pump body 6. A filter assembly 11 is fixedly connected to one end of the oil drain pipe 9. An oil guide pipe 10 is fixedly connected to one side of the filter assembly 11. A sensor assembly 14 is mounted on the outer surface of the oil guide pipe 10. The sensor assembly 14 includes a viscosity sensor 141 for monitoring oil quality and a residual carbon monitoring sensor 142, as well as a sensor for monitoring oil quality. Pressure sensor 143 and flow sensor 144 monitor the flow state. The filter assembly 11 includes a filter cylinder 111, inside which a filter screen 112 is installed. With this equipment, the circulating pump 6 drives the heat transfer oil through the oil inlet pipe 8 and the oil outlet pipe 9 into the filter assembly 11. The filter screen 112 intercepts impurities. Viscosity sensor 141 and residual carbon monitoring sensor 142 on the oil guide pipe 10 monitor the oil quality in real time. Pressure sensor 143 and flow sensor 144 monitor the flow state. If the control cabinet 3 detects that the viscosity exceeds the standard, the audible and visual alarm 4 will issue a warning, allowing the heat transfer oil to be replaced in time to avoid pipeline blockage. Production is not affected. This solves the core problems of traditional systems such as lack of monitoring, inefficient filtration, and lagging control, and provides comprehensive protection for the safe operation of the circulating system.

[0017] Viscosity sensor 141 and residual carbon monitoring sensor 142 are both installed on the lower part of the outer surface of the oil guide pipe 10, while pressure sensor 143 and flow sensor 144 are both installed on the upper part of the outer surface of the oil guide pipe 10. Installing the viscosity and residual carbon sensors at the lower part of the oil guide pipe 10 utilizes the gravity of the oil to cause heavy impurities such as residual carbon generated during deterioration to accumulate at the lower part, resulting in more accurate sensor detection. Installing pressure and flow sensor 144 at the upper part avoids interference from impurities at the lower part on flow state monitoring, ensuring the accuracy and reliability of pressure and flow data, and achieving precise zonal monitoring of quality and flow parameters. An automatic pressure relief valve is also installed on the outer surface of the oil guide pipe 10. 12. The automatic pressure relief valve 12 is located in the middle of the outer surface of the oil guide pipe 10. The automatic pressure relief valve 12 is installed in the middle of the oil guide pipe 10, between the pressure sensor 143 and the downstream pipeline. When the pressure sensor 143 detects that the pressure exceeds the standard, the pressure relief valve 12 in the middle can quickly open to relieve pressure, shorten the pressure relief path, and improve the pressure relief efficiency. The inner wall of the filter cylinder 111 is equipped with a guide plate 113, and the bottom surface of the support base 1 is equipped with a support foot. The guide plate 113 guides the heat transfer oil to form a spiral flow in the filter cylinder 111, prolonging the residence time of the oil in the filter cylinder 111, so that impurities can fully contact the filter screen 112 and improve the filtration efficiency.

[0018] A temperature sensor 16 is installed on the outer surface of the oil guide pipe 10. A data display instrument 5, electrically connected to the temperature sensor 16, is installed on the outer surface of the control cabinet 3. The temperature sensor 16 monitors the temperature of the heat transfer oil in real time and is linked to quality parameters such as viscosity and residual carbon. The control cabinet 3 can determine the impact of temperature on oil deterioration and provide a basis for system temperature control. The data display instrument 5 centrally displays the temperature and other parameters, allowing maintenance personnel to intuitively grasp the system status and improve monitoring efficiency. The control cabinet 3 is electrically connected to the sensor assembly 14, the automatic pressure relief valve 12, and the data display instrument 5 via wires. The control cabinet 3 integrates a PLC controller with preset safety thresholds and warning thresholds for each parameter, as well as a data analysis module. Pressure gauge 13 is also installed on the outer surface. Control cabinet 3 serves as the core control unit, realizing the electrical linkage of various components. When the sensor detects an abnormality, it can directly control the automatic pressure relief valve to operate without manual intervention, thus improving the emergency response speed. Pressure gauge 13 serves as a backup monitoring method for pressure sensor 143, preventing pressure monitoring failure due to sensor malfunction, thus forming a double guarantee. A bottom support plate 15 is fixedly connected to the upper surface of support base 1. The upper surface of bottom support plate 15 is connected to the bottom end of oil guide pipe 10 and the bottom surface of filter assembly 11. Bottom support plate 15 rigidly fixes oil guide pipe 10 and filter assembly 11, forming a stable pipeline support structure, thus preventing pipeline interface loosening caused by vibration during operation of circulation pump 6.

[0019] The working principle of this utility model is as follows: Place the equipment on a flat ground, adjust the level by the support feet on the bottom of the support base 1 to ensure the stability of the equipment, fix the circulating pump body 6 by the mounting bracket 7, connect the oil inlet pipe 8 to the outlet of the heat transfer oil storage tank, connect the oil guide pipe 10 to the inlet of the system heat exchanger, ensure that the pipe interface is well sealed, check the connection between the filter assembly 11 and the oil drain pipe 9 and the oil guide pipe 10 to ensure that there is no leakage, connect the control cabinet 3 to the sensor assembly 14, the automatic pressure relief valve 12, the data display instrument 5 and the circulating pump body 6 through wires, and turn on the power. During the start-up process, the power switch of the control cabinet 3 is turned on, the circulation pump 6 is started, and the heat transfer oil enters the circulation pump through the oil inlet pipe 8. After being pressurized, it enters the filter assembly 11 through the oil outlet pipe 9. After entering the filter cylinder 111, the heat transfer oil forms a spiral flow under the guidance of the guide plate 113. At the same time, impurities are intercepted by the filter screen 112. The purified heat transfer oil enters the oil guide pipe 10. The sensor assembly 14 can monitor in real time. The viscosity sensor 141 and the residual carbon monitoring sensor 142 detect the oil quality, the pressure sensor 143 and the flow sensor 144 detect the flow state, and the temperature sensor 16 detects the oil temperature. The data is transmitted to the control cabinet 3 in real time, and after being analyzed by the PLC controller and data analysis module in the control cabinet 3, it is centrally displayed on the data display instrument 5. The pressure gauge 13 displays the pressure value simultaneously. When the viscosity or residual carbon content exceeds the standard, the audible and visual alarm 4 will sound an alarm, and the data display 5 will highlight the abnormal parameters. The maintenance personnel will stop the system operation, replace the heat transfer oil, and clean the filter screen 112 of the filter assembly 11. When the pressure sensor 143 detects that the pressure exceeds the standard, the control cabinet 3 will automatically open the automatic pressure relief valve 12 to release pressure. The valve will automatically close after the pressure drops to a safe range. If the pressure continues to exceed the standard, check whether the filter assembly 11 is blocked and clean the filter screen 112. When the temperature sensor 16 detects that the oil temperature rises or falls abnormally, the data display 5 will prompt the maintenance personnel to check the heating device or cooling system and adjust it to the normal temperature.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
