Description

Technical Field

[0001] This utility model relates to the field of heat transfer oil transportation safety technology, and in particular to a splash-proof collection device. Background Technology

[0002] In industrial production, heat transfer oil pipeline systems are typically equipped with safety valves as overpressure protection devices. When the pressure inside the heat transfer oil pipeline system exceeds a set value, the safety valve automatically trips, releasing heat transfer oil through its vent pipe to reduce the pressure inside the pipeline. Currently, the vent pipes of safety valves are mostly installed vertically upwards or at an angle upwards. When the safety valve trips, the high-temperature heat transfer oil sprays directly upwards through the vent pipe, and then, due to gravity, it easily splashes onto the ground, the surface of surrounding equipment, and may even come into contact with nearby operators, leading to the following problems:

[0003] 1. Safety hazards: The temperature of high-temperature heat transfer oil usually exceeds 100°C. If it splashes onto the human body, it can cause burns. If it comes into contact with the surface of the equipment, it may cause a fire.

[0004] 2. Environmental pollution: The splashed heat transfer oil pollutes the ground and soil, which is difficult to clean and causes damage to the environment.

[0005] 3. Waste of resources: The sprayed heat transfer oil is directly lost and cannot be recycled, which increases production costs. Utility Model Content

[0016] Optionally, the guide tube assembly further includes a drainage tube, the inlet end of which is sealed to the outlet end of the connecting tube, the connecting tube having a bent section to allow the outlet end of the connecting tube to extend vertically, the outlet of the connecting tube opening vertically downward, and the drainage tube extending vertically.

[0017] The bending angle of the bent section ranges from 90° to 135°.

[0018] Optionally, the flow guiding unit further includes a support component, which includes at least one bracket for supporting the flow tube.

[0019] Optionally, the cooling unit includes a cooling jacket, which is fitted over the outside of the drain pipe. A sealed cavity is formed between the inner wall of the cooling jacket and the outer wall of the drain pipe, and the sealed cavity contains a cooling medium.

[0024] The beneficial effects of this utility model are:

[0025] This invention provides a splash-proof collection device for recovering heat transfer oil ejected from a safety valve. The device includes a flow guiding unit, a collection unit, a detection unit, and a cooling unit. The flow guiding unit comprises a flow guiding pipe assembly, the inlet of which is sealed to the outlet of the safety valve's vent pipe. The collection unit is located at the outlet of the flow guiding pipe assembly to collect the heat transfer oil within it. The detection unit detects the flow rate, pressure, and temperature of the heat transfer oil within the flow guiding pipe assembly, while the cooling unit cools the oil. This splash-proof collection device guides the heat transfer oil ejected from the safety valve into the collection unit via the flow guiding unit, and detects and cools the oil within the flow guiding pipe assembly through the detection and cooling units. This protects the collection unit from damage, ensuring that the heat transfer oil ejected from the safety valve is no longer indiscriminately sprayed but is instead orderly guided into the collection unit. This prevents heat transfer oil splashes from scalding operators, causing fires, and damaging the environment. Furthermore, the collection unit allows for the recycling of the heat transfer oil, reducing production costs. Attached Figure Description

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between 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.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In industrial production, heat transfer oil pipeline systems are typically equipped with safety valves as overpressure protection devices. When the pressure inside the heat transfer oil pipeline system exceeds a set value, the safety valve automatically trips, releasing heat transfer oil through its vent pipe to reduce the pressure inside the pipeline. Currently, the vent pipes of safety valves are mostly installed vertically upwards or at an angle upwards. When the safety valve trips, the high-temperature heat transfer oil sprays directly upwards through the vent pipe, and then, due to gravity, it easily splashes onto the ground, the surface of surrounding equipment, and may even come into contact with nearby operators, leading to the following problems:

[0034] 1. Safety hazards: The temperature of high-temperature heat transfer oil usually exceeds 100°C. If it splashes onto the human body, it can cause burns. If it comes into contact with the surface of the equipment, it may cause a fire.

[0035] 2. Environmental pollution: The splashed heat transfer oil pollutes the ground and soil, which is difficult to clean and causes damage to the environment.

[0036] 3. Waste of resources: The sprayed heat transfer oil is directly lost and cannot be recycled, which increases production costs.

[0037] Therefore, this embodiment provides a splash-proof collection device 100 to solve the above problems. The splash-proof collection device 100 can help prevent burns to operators, prevent fires, and help prevent environmental damage and reduce production costs.

[0038] like Figure 1 As shown, the anti-splash collection device 100 of this embodiment is used to recover the heat transfer oil sprayed from the safety valve 200, and includes a flow guiding unit, a collection unit, a detection unit, and a cooling unit. The flow guiding unit includes a flow guiding pipe assembly, the inlet end of which is sealed to the outlet end of the vent pipe of the safety valve 200. The collection unit is located at the outlet end of the flow guiding pipe assembly to collect the heat transfer oil within the assembly. The detection unit can detect the flow rate, pressure, and temperature of the heat transfer oil within the assembly, and the cooling unit is used to cool the heat transfer oil within the assembly.

[0039] The anti-splash collection device 100 guides the heat transfer oil sprayed from the safety valve 200 into the collection unit through the flow guiding unit. The heat transfer oil in the flow guiding pipe assembly is detected and cooled by the detection unit and the cooling unit, which can protect the collection unit from damage. This ensures that the heat transfer oil sprayed from the safety valve 200 no longer splashes indiscriminately, but is guided into the collection unit in an orderly manner. This can prevent the heat transfer oil from splashing and scalding operators, causing fires, and damaging the environment. In addition, the heat transfer oil can be recycled and reused through the collection unit, which can also reduce production costs.

[0040] Optionally, the guide pipe assembly includes a connecting pipe 1, the inlet end of which is sealed to the outlet end of the vent pipe, and the inlet end of the connecting pipe 1 is sealed to the outlet flange of the vent pipe of the safety valve 200.

[0041] Optionally, a spiral guide groove is provided on the inner wall of the connecting pipe 1, which is used to guide the flow of heat transfer oil.

[0042] Optionally, the spiral guide groove is spirally arranged and extends along the length of the connecting pipe 1 as a whole, and the ratio of the axial spacing of adjacent spiral guide grooves to the inner diameter of the connecting pipe 1 is in the range of 1-1.5.

[0043] Optionally, the depth of the spiral guide groove can be in the range of 2mm-3mm. When the heat transfer oil enters the connecting pipe 1, it smoothly turns along the spiral guide groove, which can reduce turbulence and reduce the turbulence coefficient by more than 30%. This reduces the impact wear on the inner wall of the connecting pipe 1, extends the service life of the connecting pipe 1, and also avoids vibration of the connecting pipe 1 caused by sudden changes in the flow rate of the heat transfer oil, keeping the flow noise below 60 decibels.

[0044] Optionally, the connecting pipe 1 has a bend 101 so that the pipe section at the outlet end of the connecting pipe 1 extends vertically and the outlet of the connecting pipe 1 opens vertically downward. Optionally, the bending angle of the bend 101 is in the range of 90°-135°, and the connecting pipe 1 is used to change the flow direction of the heat transfer oil sprayed from the safety valve 200 from upward to downward.

[0045] Optionally, the material selection for connecting pipe 1 should be adapted to the high temperature, high pressure, and potential corrosiveness of the heat transfer oil, and should be divided into two categories of working conditions. Under normal working conditions, i.e., when the temperature of the heat transfer oil is less than or equal to 250℃ and the heat transfer oil is non-corrosive, connecting pipe 1 should be made of Q235B seamless carbon steel, which has a short-term temperature resistance of up to 400℃ and a tensile strength of 375MPa-500MPa. It can withstand the high-pressure impact of 0.5MPa-2.5MPa when the safety valve 200 opens, and is cost-effective, meeting the economic needs of industrial modification. Under special working conditions, i.e., when the temperature of the heat transfer oil is greater than 250℃ and the heat transfer oil is slightly corrosive, connecting pipe 1 should be made of 304 / 316L stainless steel, with temperature resistance up to 800℃ and 900℃ respectively, which can resist heat transfer oil penetration corrosion and prevent seal failure.

[0046] Optionally, the diameter of connecting pipe 1 must be designed to strictly match the outlet flange specifications of the vent pipe of safety valve 200, and the inner diameter of connecting pipe 1 must not be smaller than the outlet inner diameter of the vent pipe to avoid throttling and pressure buildup. Optionally, the diameter of connecting pipe 1 is DN40-DN100. If the outlet flange of the vent pipe of safety valve 200 is DN50, connecting pipe 1 should preferably be DN50.

[0047] Optionally, the wall thickness of connecting pipe 1 should be selected based on the material and pipe diameter. For Q235B carbon steel, the wall thickness range for connecting pipe 1 with a diameter of DN40-DN65 is 3mm-5mm; for connecting pipe with a diameter of DN80-DN100, the wall thickness range is 5mm-8mm. For 304 / 316L stainless steel, the wall thickness range for connecting pipe 1 with a diameter of DN40-DN65 is 2.5mm-4mm; for connecting pipe with a diameter of DN80-DN100, the wall thickness range is 4mm-6mm.

[0048] Optionally, the guide pipe assembly also includes a drain pipe 2, the inlet end of which is sealed to the outlet end of the connecting pipe 1, and the drain pipe 2 extends vertically. Optionally, the material of the drain pipe 2 is selected according to the temperature of the heat transfer oil, and can be a seamless steel pipe or a composite flexible hose resistant to high-temperature heat transfer oil. Optionally, the drain pipe 2 can be connected to the connecting pipe 1 on the second floor of the plant and the collection unit on the first floor of the plant.

[0049] Optionally, the diversion unit also includes a support assembly (not shown in the figure), which includes at least one bracket for supporting the drainage tube 2. Multiple brackets are spaced apart along the length of the drainage tube 2 to fix the drainage tube 2 to the wall or equipment bracket and prevent leakage at the connection due to shaking of the drainage tube 2.

[0050] To ensure stable support of the drainage pipe 2, multiple supports are evenly installed along the length of the drainage pipe 2, with a standard spacing of one support every 2-3 meters. If the length of the drainage pipe 2 is greater than 10 meters, or if the diameter of the drainage pipe 2 is greater than or equal to DN80 or the inclination angle is greater than 30°, the spacing between two adjacent supports needs to be shortened to 2 meters. Furthermore, if the drainage pipe 2 has bends, such as at floor junctions, additional supports are required. Additionally, a support must be installed within 1 meter of the lower end of the drainage pipe 2, close to the collection bucket 7, to prevent the end of the drainage pipe 2 from swaying and causing misalignment with the opening of the collection bucket 7.

[0051] Optionally, when the bracket is connected to a concrete or brick wall, it can be fixed with M8-M12 expansion bolts, with a drilling depth of ≥60mm. Each bracket should be equipped with at least two bolts symmetrically arranged, making installation convenient and removable. When the bracket is connected to a steel equipment bracket, it can be fixed by welding, with full welding on the contact surface and a weld height of ≥5mm. Rust prevention treatment should be applied after welding to ensure high connection strength and vibration resistance.

[0052] Optionally, a 3mm-5mm thick oil-resistant rubber pad can be placed at the contact point between the bracket and the drainage tube 2 to reduce vibration wear or metal electrochemical corrosion. The bracket should avoid the cooling unit, or a custom-made "U-shaped support bracket" can be used to support the bottom of the cooling unit and prevent it from being squeezed.

[0053] Optionally, the detection unit includes a pressure sensor 13, which is installed in the middle section of the drainage tube 2, 1-2 meters away from the connecting tube 1. The pressure sensor 13 has a range of 0-4 MPa and an accuracy of ±0.05 MPa, and can monitor the pressure inside the drainage tube 2 in real time. Optionally, when the pressure exceeds 1.2 times the opening pressure of the safety valve 200, an alarm can be automatically or manually triggered.

[0054] Optionally, the detection unit also includes a temperature sensor 14, which is installed on the same side as the pressure sensor 13. The temperature sensor 14 has a range of 0-350℃ and an accuracy of ±1℃. The temperature sensor 14 is used to monitor the temperature of the heat transfer oil in the drain pipe 2. Optionally, when the temperature sensor 14 detects a temperature exceeding 300℃, an alarm can be automatically or manually triggered to issue a high-temperature warning.

[0055] Optionally, the detection unit also includes a flow sensor 12, which is installed at the end of the drain pipe 2, 0.5-1 meter from the collection tank 7. The flow sensor 12 has a range of 0-100 L / min and an accuracy of ±2%, and is used to monitor the flow rate of the heat transfer oil in the drain pipe 2. Optionally, when the flow sensor 12 detects a sudden change in flow rate, such as a drop of more than 50%, it may indicate a blockage in the connecting pipe 1 or the drain pipe 2, and can automatically or manually trigger an alarm.

[0056] Optionally, in some embodiments, all sensors can be connected to the controller via wireless signals or wired cables. The controller can output alarm signals to on-site audible and visual alarms and remote monitoring terminals. Optionally, the controller can be a Zhejiang Zhongkong JX-300XP. Since the controller is existing technology, it will not be described in detail here.

[0057] Alternatively, in other embodiments, the detection results of each sensor can be read manually, and the alarm can be triggered manually.

[0058] Optionally, the cooling unit includes a cooling jacket 3, which is fitted over the outer side of the drain pipe 2. A sealed cavity is formed between the inner wall of the cooling jacket 3 and the outer wall of the drain pipe 2, and the sealed cavity contains a cooling medium. Optionally, in this embodiment, the cooling jacket 3 is fitted over the middle section of the drain pipe 2. The cooling jacket 3 is used to reduce the temperature of the high-temperature heat transfer oil, protect the collection unit, and improve safety.

[0059] Optionally, in this embodiment, the cooling jacket 3 is made of 304 stainless steel, which is resistant to cooling water corrosion, and the inner diameter of the cooling jacket 3 is 10-15 mm larger than the outer diameter of the drain pipe 2. The two ends of the cooling jacket 3 in the vertical direction are sealed to the outer wall of the drain pipe 2 through flanges to form a closed sealing cavity.

[0060] Optionally, the sealing cavity has an inlet pipe 4 and an outlet pipe 5. A regulating valve 6 is installed on the inlet pipe 4 to regulate the flow rate of the cooling medium within the inlet pipe 4. Alternatively, the sealing cavity also has an outlet pipe 5.

[0061] Optionally, the cooling medium is industrial circulating cooling water with a temperature of 30°C or less. The inlet of the sealed cavity is located at the lower end of the cooling jacket 3, and the outlet of the sealed cavity is located at the upper end of the cooling jacket 3. That is, the cooling medium adopts a counter-current flow method, entering from the lower end of the cooling jacket 3 and exiting from the upper end, forming a reverse heat exchange with the heat transfer oil flowing from top to bottom in the guide pipe 2, which can increase the average temperature difference between the hot and cold fluids and improve the heat exchange efficiency.

[0062] Alternatively, in other embodiments, the cooling unit may also employ a wound cooling coil wound around the outside of the drain pipe 2.

[0063] Optionally, in some embodiments, the detection result of the temperature sensor 14 is read manually, and the regulating valve 6 is adjusted according to the cooling requirements to regulate the flow rate of the cooling medium in the inlet pipe 4. In other embodiments, a controller can also be used to obtain the result of the temperature sensor 14 and control the regulating valve 6. When the detection result of the temperature sensor 14 is greater than 200°C, the regulating valve 6 is opened; when the detection result of the temperature sensor 14 drops to below 80°C, the regulating valve 6 is closed to ensure that the temperature of the heat transfer oil flowing into the collection unit is less than or equal to 80°C, thereby extending the service life of the collection unit and avoiding safety risks caused by high-temperature heat transfer oil.

[0064] Optionally, the collection unit includes a collection tank 7 and a first liquid level sensor 8. The outlet end of the drain pipe 2 is located inside the collection tank 7, and the first liquid level sensor 8 is used to detect the liquid level of the heat transfer oil in the collection tank 7.

[0065] Optionally, under normal operating conditions, i.e., when the heat transfer oil temperature is less than or equal to 120℃ and collection is infrequent, the collection tank 7 is made of high-density polyethylene, with a temperature resistance range of 80-120℃, and is resistant to oil penetration, resulting in low cost. Under special operating conditions, i.e., when the heat transfer oil temperature is greater than 120℃ and frequent collection is required, the collection tank 7 is made of Q235B carbon steel, with an epoxy resin oil-resistant coating on the inner wall to achieve unlimited temperature resistance, high structural strength, and the coating can prevent carbon steel corrosion from contaminating the heat transfer oil.

[0066] Optionally, the capacity of the collection tank 7 needs to be greater than the total discharge capacity of the safety valve 200 in a single trip, with a buffer space of 10%-20%. Under normal circumstances, the capacity of the collection tank 7 is 1000L-2000L. If the single discharge capacity of the safety valve 200 is 500L / h and the release time is less than or equal to 2 hours, then a 1000L ton tank can be selected.

[0067] Optionally, the end of the drain pipe 2 extends into the opening of the collection tank 7, and the distance between the end of the drain pipe 2 and the bottom surface of the collection tank 7 needs to be greater than or equal to 10cm, so as to avoid the heat transfer oil from impacting the bottom surface and gushing out of the collection tank 7 when the distance is too close.

[0068] Optionally, the first liquid level sensor 8 is an ultrasonic liquid level sensor or a float-type liquid level sensor with a range of 0-200cm to adapt to the height of a 2000L ton container, and an accuracy of ±1cm. The first liquid level sensor 8 is used to monitor the oil level in the collection tank 7 in real time. Optionally, the first liquid level sensor 8 is communicatively connected to the controller. When the oil level reaches 80% of the total capacity, the controller triggers an alarm to issue a first-level alarm. When the oil level reaches 90% of the total capacity, the controller triggers a second-level alarm, and the alarm signal is synchronously transmitted to the remote monitoring system.

[0069] In other embodiments, the detection result of the first liquid level sensor 8 can also be read manually, and the alarm can be triggered manually when the liquid level is too high.

[0070] Optionally, the collection unit also includes an overflow pipe 9 and a spare collection tank 10. The overflow pipe 9 is used to guide the heat transfer oil in the collection tank 7 that exceeds the preset height into the spare collection tank 10.

[0071] Optionally, the overflow pipe 9 has a diameter of DN25-DN50 to match the diameter of the drain pipe 2. Typically, the diameter of the overflow pipe 9 is 1 / 2 to 2 / 3 of the diameter of the drain pipe 2. For example, if the drain pipe 2 is DN50, then the overflow pipe 9 should be DN25-DN32. This avoids both excessively small diameters that could cause blockages and poor overflow, and excessively large diameters that could lead to excessive fluctuations in the oil level within the collection tank 7. Optionally, the inlet of the overflow pipe 9 is positioned 5cm-10cm from the top of the collection tank 7 to form a warning buffer section.

[0072] Optionally, the collection unit also includes an overflow valve 11, which is installed on the overflow pipe 9 and used to regulate the flow rate of the heat transfer oil in the overflow pipe 9. Optionally, the overflow valve 11 is installed in the middle section of the overflow pipe 9 and can be a self-regulating flow control valve. It automatically adjusts the valve opening according to the flow velocity of the heat transfer oil in the overflow pipe 9; a faster flow velocity results in a larger opening, and a slower flow velocity results in a smaller closing, ensuring that the oil level in the collection tank 7 remains stable at 2-3 cm below the inlet of the overflow pipe 9, thus avoiding frequent overflows. Optionally, the overflow valve 11 can also be an electrically adjustable valve, linked to the flow sensor 12 of the drain pipe 2.

[0073] Optionally, the capacity of the spare collection tank 10 is the same as that of the collection tank 7. Optionally, a second liquid level sensor is also installed on the inner wall of the spare collection tank 10. When the oil level in the spare collection tank 10 reaches 80%, an alarm is triggered to remind the operator to replace the collection tank 7 and the spare collection tank 10 in time.

[0074] The anti-splash collection device 100 can be designed with different extension methods for the diversion pipe 2 according to the actual conditions of different factory buildings. Through the connecting pipe 1 and the diversion pipe 2, the heat transfer oil is directed to the collection unit, preventing splashing onto personnel and equipment and eliminating the risk of burns and fire. Furthermore, using this anti-splash collection device 100 to collect the heat transfer oil centrally at the collection unit avoids pollution of the ground and soil, preventing environmental damage. The collected heat transfer oil can also be treated and reused, reducing production costs. Upgrading to use this anti-splash collection device 100 only requires the addition of the connecting pipe 1, diversion pipe 2, and collection unit, making it easy to install, requiring minimal modification to the original system, and resulting in low cost.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
