Abstract
Description
Technical Field
[0001] This invention relates to the field of auxiliary equipment technology for marine separators, specifically to a marine separator oil inlet temperature control device. Background Technology
[0002] Marine separators are core equipment for purifying and treating marine fuel oil and lubricating oil, and their separation performance directly affects the operational stability of the ship's power system. During operation, the oil temperature at the feed inlet is a critical factor: Too low a temperature leads to increased oil viscosity and decreased fluidity, reducing separation efficiency and potentially causing blockages inside the separator; too high a temperature causes rapid evaporation of water from the oil, with vapor mixing into the purified oil and affecting its purity. Simultaneously, high temperatures accelerate oil oxidation and deterioration, shortening the oil's service life.
[0003] To address the aforementioned issues, existing technologies typically involve installing a single plate heat exchanger at the front end of the separator's feed inlet to regulate the oil temperature through heat exchange. However, in practical applications, there are several shortcomings: First, during ship navigation, there are complex operating conditions such as turbulence, fluctuations in oil supply flow, and unstable temperatures of heat exchange media (such as seawater and steam), resulting in frequent and uneven fluctuations in oil supply temperature. The heat exchange response speed of a single plate heat exchanger is limited, making it difficult to quickly adapt to different fluctuation scenarios, and the oil temperature fluctuates continuously. Second, the existing dual heat exchanger solution only switches between uses and does not have functions designed to address the differences in oil temperature fluctuation amplitude, resulting in insufficient temperature control accuracy and efficiency. Third, after shutdown, the oil remaining in the heat exchanger and connecting pipes will not only affect the next startup due to increased viscosity from cooling, but may also adhere to the walls, deteriorate, and contaminate new oil. Existing back-pull structures are mostly single-pull liquid modes, which are difficult to completely remove residual oil films. Fourth, there is a lack of real-time perception and prediction of ship operating conditions, resulting in lag in temperature control operations, which further exacerbates oil temperature fluctuations. Fifth, the existing system cannot adapt to the differentiated needs of different types of ship oil, and the temperature control parameters are fixed, resulting in insufficient versatility. Sixth, the heat exchange structure design of the rapid temperature-regulating heat exchanger is simple, and the turbulence effect is limited, restricting the temperature regulation speed.

A solenoid valve is provided at the connection between the U-shaped tube and the tee pipe.
[0009] Furthermore, the operating condition sensing module includes an inlet temperature sensor, an oil supply flow sensor, an oil viscosity sensor, an oil supply temperature sensor, a ship attitude sensor, a residual oil level detection sensor, a heat exchange medium temperature sensor, a pipeline pressure sensor, and a control box. The control box is connected to the inlet temperature sensor, oil supply flow sensor, oil viscosity sensor, oil supply temperature sensor, ship attitude sensor, residual oil level detection sensor, heat exchange medium temperature sensor, pipeline pressure sensor, intelligent three-way valve, return pump, and purging air pump.
[0010] Furthermore, the feed inlet temperature sensor is located at the connection between the two-way pipe and the marine separator, with the measuring end of the feed inlet temperature sensor extending into the two-way pipe. The heat exchange medium temperature sensor is located at the connection between the heat exchange inlet medium pipe and the rapid temperature-regulating heat exchanger and the precise temperature-stabilizing heat exchanger, with the sensing end of the heat exchange medium temperature sensor extending into the heat exchange inlet medium pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The working condition sensing module monitors in real time the working status of the rapid temperature-regulating heat exchanger, the precise temperature-stabilizing heat exchanger, the adaptive back-pull component, the sweeping component, and the T-pipe II, as well as the status of the oil during the oil flow process. Then, it predicts the state of the oil in a short period of time. Through the synergistic effect of the rapid temperature-regulating heat exchanger and the precise temperature-stabilizing heat exchanger, it can ensure that the oil temperature input into the marine separator can be adjusted in a timely manner when the oil temperature fluctuates greatly. When the predicted oil temperature deviates significantly from the set range, the operating condition sensing module controls the intelligent three-way valve to switch to a rapid temperature-regulating heat exchanger to quickly raise or lower the oil temperature to near the set value. When the oil temperature enters the vicinity of the set range, it switches to a precise temperature-stabilizing heat exchanger to fine-tune the power. If the oil supply flow fluctuates drastically, the rapid temperature-regulating heat exchanger and the precise temperature-stabilizing heat exchanger are connected simultaneously for mixed temperature control, increasing the anti-interference strength against excessive oil supply. Furthermore, the mixing of oils input into the three-way pipe avoids the problem of large fluctuations in the output oil of the rapid temperature-regulating heat exchanger and the precise temperature-stabilizing heat exchanger. When oil supply is stopped, the residual oil in the rapid temperature-regulating heat exchanger and the precise temperature-stabilizing heat exchanger is drawn back by the adaptive back-drawing component. This avoids the problem of residual oil in the heat exchanger and connecting pipes after shutdown, which would not only affect the next startup due to increased viscosity caused by cooling, but also may cause the oil to stick to the wall, deteriorate and contaminate the new oil. The pipeline of the adaptive back-drawing component is cleaned by the purging component to ensure the cleaning effect of residual oil. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0019] Example 1 Please see Figures 1-10This invention provides a technical solution: a marine separator oil inlet temperature control device, comprising a rapid temperature-adjusting heat exchanger 2, a precise temperature-stabilizing heat exchanger 3, a three-way pipe 2 7, and an oil inlet main pipe 14. The heat exchange medium circulation ports of the rapid temperature-adjusting heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 are connected to heat exchange inlet medium pipes 22. The liquid outlets of the rapid temperature-adjusting heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 are connected to the two right ends of the three-way pipe 2 7, and the left end of the three-way pipe 2 7 is connected to the liquid inlet end of the marine separator 1. An intelligent three-way valve 8 is installed at the center of the three-way pipe 2 7. The right end of the oil inlet main pipe 14 is connected to the liquid inlet end of the rapid temperature-adjusting heat exchanger 2, and an oil inlet branch pipe 15 is connected to the oil inlet main pipe 14. The right end of the oil branch pipe 15 is connected to the liquid inlet of the precision temperature-stabilized heat exchanger 3. An adaptive backflow component 5 is installed below the rapid temperature-regulating heat exchanger 2 and the precision temperature-stabilized heat exchanger 3. The negative pressure end of the adaptive backflow component 5 is connected to the liquid inlet and outlet of the rapid temperature-regulating heat exchanger 2 and the precision temperature-stabilized heat exchanger 3. A purging assembly 6 is installed on the outside of the adaptive backflow component 5. The air outlet of the purging assembly 6 is connected to the output end of the adaptive backflow component 5. Operating condition sensing modules are installed at the input and output points of the adaptive backflow component 5, the purging assembly 6, and the rapid temperature-regulating heat exchanger 2 and the precision temperature-stabilized heat exchanger 3. These operating condition sensing modules monitor the rapid temperature-regulating heat exchanger 2 and the precision temperature-stabilized heat exchanger 3 in real time. The system monitors the working status of the heat exchanger 3, adaptive backflow component 5, sweeping assembly 6, and three-way pipe 7, as well as the state of the oil during flow. It then predicts the oil's state in a short period and, through the synergistic action of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3, ensures timely adjustment of the oil temperature input to the marine separator 1 even when oil temperature fluctuations are significant. When the predicted oil temperature deviates significantly from the set range, the operating condition sensing module controls the intelligent three-way valve 8 to switch to the rapid temperature-regulating heat exchanger 2, quickly raising or lowering the oil temperature to near the set value. When the oil temperature approaches the set range, it switches to the precise temperature-stabilizing heat exchanger 3 to fine-tune the power. If the oil supply flow fluctuates drastically, it simultaneously connects the rapid temperature-regulating heat exchanger 2... The temperature control of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 is mixed to increase the anti-interference strength against excessive oil supply. The mixing of oil when it is input into the three-way pipe 2 7 avoids the problem of large fluctuations in the output oil of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3. When the oil supply stops, the residual oil of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 is drawn back by the adaptive back-extraction component 5. This avoids the problem that the residual oil in the heat exchanger and connecting pipes after shutdown will not only affect the next start-up due to increased viscosity due to cooling, but may also cause the oil to stick to the wall, deteriorate and contaminate the new oil. The back-extraction pipeline of the adaptive back-extraction component 5 is cleaned by the purging component 6 to ensure the cleaning effect of residual oil. The rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 are equipped with a support 4 at their bottom. The support 4 supports the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3. The rapid temperature-regulating heat exchanger 2, the precise temperature-stabilizing heat exchanger 3, the adaptive back-extraction component 5, and the sweeping assembly 6 are all housed in an equipment compartment 9. The back of the equipment compartment 9 is equipped with a maintenance door 10 for easy access. The equipment compartment 9 is used to house the rapid temperature-regulating heat exchanger 2, the precise temperature-stabilizing heat exchanger 3, the adaptive back-extraction component 5, and the sweeping assembly 6. The blowing assembly 6 is protected to prevent seawater from damaging the rapid temperature-regulating heat exchanger 2, the precise temperature-stabilizing heat exchanger 3, the adaptive backflow component 5, and the blowing assembly 6 during ship navigation. An inspection door 10 is provided to facilitate workers to inspect the internal structure of the equipment compartment 9. A bracket 4 is provided to support the installation of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3, and to separate the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 from the adaptive backflow component 5 and the blowing assembly 6. The adaptive backflow component 5 includes an oil storage tank 501 and a backflow pump 502. The oil storage tank 501 and backflow pump 502 are located inside the support 4. The output end of the backflow pump 502 is connected to the inlet end of the oil storage tank 501. The input end of the backflow pump 502 is connected to a three-way pipe 503. The top two ports of the three-way pipe 503 are respectively connected to branch pipe 504 and branch pipe 505. The top two ports of branch pipe 504 are respectively connected to the inlet and outlet ends of the rapid temperature-regulating heat exchanger 2. The top two ports of branch pipe 505 are respectively connected to the inlet and outlet ends of the precision temperature-stabilizing heat exchanger 3. Solenoid valve 506 is installed at the connection points between branch pipe 504 and branch pipe 505 and the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3. The residual oil in the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 is drawn back through branch pipe 504 and branch pipe 505, which are connected to the liquid inlet and outlet of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3. The drawn-back residual oil is input into the oil storage tank 501 by the return pump 502 for temporary storage. Solenoid valve 506 is set to specifically draw back the rapid temperature-regulating heat exchanger 2 or the precise temperature-stabilizing heat exchanger 3, so as to improve the accuracy of the drawback and thus improve the drawback efficiency. The purging assembly 6 includes a purging air pump 601, which is located inside the bracket 4. The output end of the purging air pump 601 is connected to a U-shaped pipe 602. The top end of the U-shaped pipe 602 is connected to a U-shaped pipe 603. The two ports on the left side of the U-shaped pipe 603 are connected to the two top ports of the three-way pipe 503, respectively. A solenoid valve 604 is installed at the connection between the U-shaped pipe 603 and the three-way pipe 503. The purging air is generated by the purging air pump 601 and enters the U-shaped pipe 603 from the U-shaped pipe 602. The corresponding solenoid valve 604 is opened, so that the purging air enters the corresponding port of the three-way pipe 503 and then enters the corresponding branch pipe 504 or branch pipe 505 to purge the branch pipe 504 or branch pipe 505 that participates in the residual oil back-extraction.
[0020] Working Principle: During use, oil enters through the main oil inlet pipe 14. The oil condition monitoring module monitors the oil status. When the predicted oil temperature deviates significantly from the set range, the monitoring module controls the intelligent three-way valve 8 to switch to the rapid temperature-regulating heat exchanger 2, quickly raising or lowering the oil temperature to near the set value. When the oil temperature approaches the set range, it switches to the precise temperature-stabilizing heat exchanger 3 to fine-tune the power. If the oil supply flow fluctuates drastically, the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 are connected simultaneously for mixed temperature control, increasing the anti-interference strength against excessive oil supply. Furthermore, the mixing of oil entering the three-way pipe 7 prevents the output of the rapid temperature-regulating heat exchanger 2 and the precise temperature-stabilizing heat exchanger 3 from being too high. To address the issue of significant oil fluctuations during shutdown, the corresponding solenoid valve 506 is opened based on the operational level of the rapid temperature-regulating heat exchanger 2 or the precise temperature-stabilizing heat exchanger 3. This allows the return pump 502 to return the oil from either the rapid temperature-regulating heat exchanger 2 or the precise temperature-stabilizing heat exchanger 3 to the oil storage tank 501. Near the end of the return process, the purging air pump 601 is activated to generate purging air. Then, the solenoid valve 604 of the corresponding branch pipe 504 or branch pipe 505 is opened, allowing the purging air to enter the branch pipe 504 or branch pipe 505 to clean them and ensure that no residual oil remains in the pipeline.

If the pressure is too high, another heat exchanger can be temporarily opened to stabilize the oil pressure. The oil supply regulating valve 20 is set to stabilize the oil flow rate, so that the temperature monitoring of the oil supply temperature sensor 19 is more accurate. The ship attitude sensor 13 is installed in the equipment compartment 9. A shock absorber 12 is provided at the connection between the ship attitude sensor 13 and the equipment compartment 9. The shock absorber 12 is fixedly installed in the equipment compartment 9. The ship attitude sensor 13 is installed in the shock absorber 12. The shock absorber 12 reduces the impact of mechanical vibration on the ship attitude sensor 13. The ship attitude sensor 13 captures the ship's pitching angle and, together with the sensors in other sensing modules, provides the control box 11 with the basis for operating condition decision-making.
[0022] Working principle: During use, when the oil enters the oil inlet main pipe 14, the oil flow rate is first adjusted by the oil supply regulating valve 20. Then, the oil condition is monitored by the oil supply flow sensor 17, the oil viscosity sensor 18, and the oil supply temperature sensor 19. The monitored data is transmitted to the control box 11. The control box 11 can predict changes in the oil in a short period of time and then adjust the oil temperature in advance by adjusting the rapid temperature regulating heat exchanger 2, the precise temperature stabilizing heat exchanger 3, and the intelligent three-way valve 8 to ensure that the oil temperature is not too high or too low when it enters the marine separator 1.
[0023] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
