Description

Technical Field

[0001] The present disclosure relates to the technical field of engine oil purification, and in particular, to an engine oil purification system. Background Art

[0002] The purpose of setting up the lubricating oil purification system is to filter and purify the lubricating oil in the main oil tank of the turbine so that the oil quality of the lubricating oil meets the use requirements, and then return the purified lubricating oil to the main oil tank of the turbine.

[0003] During installation, the main oil tank is located higher than the purification system, resulting in a height difference. During actual operation, when the purification system fails and trips, the oil in the main oil tank will enter the vacuum oil tank of the purification system through static pressure. Over time, when the vacuum oil tank is full of oil, it will overflow from the breather. If it is not discovered in time, a large amount of oil leakage will occur, threatening the safe operation of the turbine and causing environmental pollution. Utility Model Content

[0004] The purpose of the present disclosure is to provide an engine oil purification system, which can solve the above technical problems.

[0005] In order to achieve the above-mentioned objectives, the present disclosure provides an oil purification system, comprising: a main oil tank; a purification device, connected to the main oil tank and at a height lower than the main oil tank, for purifying the lubricating oil in the main oil tank; and a stop-flow component, the purification device comprising a vacuum oil tank, the stop-flow component being arranged between the main oil tank and the vacuum oil tank, the stop-flow component being electrically connected to the purification device so as to be closed when the purification device is powered off.

[0006] Optionally, the overflow stopper is arranged at the outlet of the main oil tank or at the inlet of the purification device.

[0007] Optionally, a control valve is provided at the inlet of the purification device, and the overflow stop is provided at the outlet end of the control valve.

[0008] Optionally, the overflow stop is constructed as a solenoid valve that opens when energized and closes when de-energized.

[0009] Optionally, the oil purification system further includes a switch feedback device, which is connected to the overflow stop member.

[0010] Optionally, the switch feedback device is configured as an indicator light, which is electrically connected to the solenoid valve so as to light up when the solenoid valve is energized and go out when the solenoid valve is de-energized.

[0011] Optionally, the solenoid valve is electrically connected to a control system of the purification device, so that the solenoid valve is opened simultaneously when the purification system is turned on.

[0012] Optionally, a manual valve is provided between the main oil tank and the vacuum oil tank.

[0013] Optionally, a liquid level measuring device is provided in the vacuum oil tank.

[0014] Optionally, the oil purification system is a purification system for the lubricating oil of a main engine of a thermal power unit.

[0015] Through the above technical solution, since the position of the main oil tank is higher than the purification device during installation, when the purification device fails and trips, the oil in the main oil tank will enter the vacuum oil tank through static pressure, causing the vacuum oil tank to overflow. Therefore, a stop-flow component is set between the main oil tank and the purification device. The stop-flow component can be closed when the purification device trips and loses power, thereby closing the oil circuit between the main oil tank and the vacuum oil tank, preventing the oil in the main oil tank from leaking into the vacuum oil tank, and ensuring the safe operation of the system.

[0016] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0022] In this disclosure, unless otherwise indicated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom positions of the corresponding component in the direction of gravity when in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not convey order or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.

[0023] like Figure 1As shown, the present disclosure provides an oil purification system, comprising: a main oil tank 1; a purification device 2, which is connected to the main oil tank 1 and is lower in height than the main oil tank 1, and is used to purify the lubricating oil in the main oil tank 1; and a stop-flow component 3, the purification device 2 includes a vacuum oil tank 21, the stop-flow component 3 is arranged between the main oil tank 1 and the vacuum oil tank 21, and the stop-flow component 3 is electrically connected to the purification device 2 so as to be closed when the purification device 2 is powered off.

[0024] Through the above technical solution, since the position of the main oil tank 1 is higher than the purification device 2 during installation and there is a height difference, when the purification device 2 fails and trips, the oil in the main oil tank 1 will enter the vacuum oil tank 21 through static pressure, causing the vacuum oil tank 21 to overflow. Therefore, a stop-flow component 3 is provided between the main oil tank 1 and the purification device 2. The stop-flow component 3 can be closed when the purification device 2 trips and loses power, thereby closing the oil circuit between the main oil tank 1 and the vacuum oil tank 21, preventing the oil in the main oil tank 1 from leaking into the vacuum oil tank 21, and ensuring the safe operation of the system.

[0025] As an optional implementation, Figure 1 As shown, the overflow stopper 3 is arranged at the outlet of the main oil tank 1 or the inlet of the purification device 2 to prevent the oil in the main oil tank 1 from entering the purification device 2.

[0026] Optionally, a control valve 4 is provided at the inlet of the purification device 2, and the overflow stop 3 is provided at the outlet end of the control valve 4. That is, the overflow stop 3 is provided at the inlet of the purification device 2. The control valve 4 is used to normally control the opening or closing of the connection between the purification device 2 and the main oil tank 1. The overflow stop 3 is in a normally open state when powered on and cannot be used as a conventional valve. Therefore, the overflow stop 3 is provided at the outlet end of the control valve 4. Of course, in other embodiments, the overflow stop 3 can also be provided at the outlet of the main oil tank 1.

[0027] As an optional implementation, Figure 1 As shown, the overflow stop member 3 is constructed as a solenoid valve that opens when powered and closes when powered off. The solenoid valve uses the principle of electromagnetism. When powered on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens. When powered off, the electromagnetic force disappears, and the spring presses the closing member onto the valve seat, and the valve closes. When the purification device 2 is normally powered on, the solenoid valve is in a normally open state. When the purification device 2 loses power, the other valves lose control. At this time, the solenoid valve closes, closing the pipeline to prevent the oil in the main oil tank 1 from flowing into the vacuum oil tank 21. Of course, in other embodiments, a backup circuit can also be provided. When it is detected that the purification device 2 is powered off, the backup circuit is turned on, thereby controlling the operation of the overflow stop member 3 to close the oil circuit.

[0028] Optionally, the oil purification system further includes a switch feedback device 5, which is connected to the overflow stop part 3. The switch feedback device 5 is used to feedback the switch status of the overflow stop part 3, so that the staff can observe whether the overflow stop part 3 is working normally.

[0029] Among them, the switch feedback device 5 is constructed as an indicator light, which is electrically connected to the solenoid valve so as to light up when the solenoid valve is energized and go out when the solenoid valve is de-energized. That is, the indicator light and the solenoid valve share a circuit. When the solenoid valve is energized, the indicator light is energized and is in a normally open state. When the solenoid valve is de-energized, the indicator light is also de-energized and goes out, which is used to indicate the on / off status of the solenoid valve.

[0030] Optionally, the solenoid valve is electrically connected to the control system of the purification device 2 so that the solenoid valve is opened at the same time when the purification system is turned on. The control system is the switching system of the purification device 2. When the purification device 2 is turned on, the solenoid valve is opened in conjunction with it, and there is no need to open the solenoid valve separately, to prevent forgetting to open the solenoid valve. Similarly, when the purification system is powered off, the solenoid valve loses power.

[0031] As an optional implementation, Figure 1 As shown, a manual valve 6 is provided between the main oil tank 1 and the vacuum oil tank 21 for manually controlling the closing of the oil circuit between the main oil tank 1 and the vacuum oil tank 21 , thereby adding a safety measure to further prevent oil overflow from the vacuum oil tank 21 .

[0032] Optionally, a liquid level measuring device 22, such as a liquid level sensor, is provided in the vacuum oil tank 21 for measuring the liquid level in the vacuum oil tank 21. When the liquid level is too high, the oil circuit between the main oil tank 1 and the vacuum oil tank 21 can be manually closed to prevent the vacuum oil tank 21 from overflowing when the solenoid valve is damaged or fails to work properly.

[0033] As an optional embodiment, the oil purification system is a purification system for the lubricating oil of the main engine of the thermal power unit, which is used to purify the lubricating oil of the turbine unit of the thermal power plant, such as a 1000MW unit. The normal operation of the lubricating oil system is of great significance to ensuring the safe operation of the turbine. The oil purification system is an extremely important device to ensure that the lubricating oil system can work normally, ensuring that the physical and chemical properties and cleanliness of the lubricating oil in the system can meet the use requirements. The present disclosure is provided with a stop-flow part 3, which can be closed when the purification device 2 trips and loses power, thereby closing the oil circuit between the main oil tank 1 and the vacuum oil tank 21, preventing the oil in the main oil tank 1 from leaking to the vacuum oil tank 21, and ensuring the safe operation of the system.

[0034] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0036] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
