Description

Technical Field

[0001] This invention relates to the field of gas turbine oil monitoring technology, specifically a blockage alarm and automatic reverse cleaning device, system and method for gas turbine oil monitoring. Background Technology

[0002] During gas turbine operation, the oil requires regular testing to check its viscosity, density, moisture content, acid value, dielectric constant, temperature, and metal abrasive particles. This is to detect abnormalities such as oil deterioration and equipment wear. Traditional oil testing uses laboratory analysis methods, involving manual sampling followed by laboratory analysis. Later, online oil monitoring systems were introduced for real-time monitoring of the lubricating oil. In this system, lubricating oil from the gas turbine's drain port enters the oil sampling line 'a'. As it travels along this line, it passes through a filter and a sampling mechanism. Real-time data is monitored by sensors. The filter removes metal abrasive particles, preventing blockage of the sampling mechanism. Sensors are typically placed before and after the filter to collect real-time flow data. When other data are normal, but the sensor detects that the oil flow rate after the filter is significantly lower than the flow rate before it, the filter is considered blocked and needs immediate cleaning. The filter is usually made of stainless steel.

[0003] Existing devices often use scrapers to remove filter material from the surface of stainless steel filter screens during the cleaning process. This method does not allow for reverse cleaning of the stainless steel filter screens, resulting in metal abrasive particles remaining in the mesh of the stainless steel filter screens and incomplete cleaning of the filter components. Summary of the Invention

[0004] The purpose of this invention is to provide a blockage alarm and automatic reverse cleaning device, system and method for monitoring oil in gas turbines, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a blockage alarm and automatic reverse cleaning device for gas turbine oil monitoring, the device comprising: A cleaning tank with a liquid inlet; The three-way pipe includes a positive pressure filling pipe, a negative pressure suction pipe, and a connecting pipe. The positive pressure filling pipe and the negative pressure suction pipe are respectively equipped with a filling check valve and a suction check valve. The positive pressure filling pipe and the negative pressure suction pipe are both connected to the cleaning tank. The connecting pipe is connected to a branch of the oil sampling pipeline a. A two-way pressure control valve is located on the cleaning tank, with one end connected to the inside of the cleaning tank and the other end connected to the vacuum pump. In negative pressure mode, the blockage in the oil sampling line a is extracted and discharged in reverse after passing through the connecting pipe, the suction check valve, the negative pressure suction pipe, the cleaning tank, the two-way pressure control valve, and the vacuum pump. In positive pressure mode, the cleaning fluid enters the cleaning tank, the positive pressure filling pipe, the filling check valve, the connecting pipe, and the oil sampling line a from the inlet to clean the blockage.

[0006] Furthermore, the starting end of the oil sampling pipeline a is connected to the gas turbine oil outlet; along the oil flow direction, the oil sampling pipeline a is also provided with a filtration mechanism and a sampling mechanism in sequence, and the branch where the connecting pipe is located is located before the filtration mechanism.

The cleaning box includes an inner ring and an outer ring that are concentrically connected. The partition block and the filter screen are fixed radially on the inner ring. A cavity is formed between the partition block, the inner ring, and the outer ring, and the filter screen is located in the cavity. Branch pipe one and branch pipe two are symmetrically connected on both sides of the cleaning box. The cleaning box is connected in series in the oil sampling pipeline a through branch pipe one and branch pipe two. In the filtration state, the filter surface b of the filter screen faces branch pipe one.

[0009] Furthermore, the filtration mechanism also includes a power component mounted on the cleaning box, which drives the inner ring to rotate within the cleaning box to adjust the direction and position of the filter surface b of the filter screen.

[0010] Furthermore, the device also includes a density sensor, a viscosity sensor, a moisture sensor, a temperature sensor installed on the sampling mechanism, and a flow rate sensor installed on the oil sampling line a. The flow rate sensor is used to detect the flow rate difference of the oil before and after the oil sampling line a. If the flow rate difference exceeds the threshold, the oil sampling line a will be blocked, and the alarm will sound.

[0011] Furthermore, the cleaning tank includes a tank body and a cap. A connecting inner sleeve is fixedly connected to the inner wall of the cap, and an external thread is provided on the outer side of the connecting inner sleeve. An internal thread that mates with the connecting inner sleeve is provided at the open end of the tank body. The positive pressure filling pipe is connected to the bottom of the tank body, and the negative pressure suction pipe is connected to the top of the tank body.

[0012] Furthermore, the filtration mechanism also includes a paper filter element and a polytetrafluoroethylene filter membrane sequentially arranged on the oil sampling pipeline a, wherein the paper filter element is located between the branch pipe two and the polytetrafluoroethylene filter membrane; an electromagnetic regulating valve one is provided on the oil sampling pipeline a, wherein the electromagnetic regulating valve one is located between the branch pipe two and the polytetrafluoroethylene filter membrane.

[0013] A gas turbine oil monitoring blockage alarm and automatic backwashing system, the system comprising: The sampling module is connected to the oil sampling pipeline a and is used to control the operation of the oil sampling pipeline a so that the oil from the gas turbine outlet is pre-treated by the filtration mechanism before reaching the sampling mechanism.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0018] See Figures 1-4 This invention provides a technical solution: a blockage alarm for oil monitoring in a gas turbine and a blockage alarm and automatic reverse cleaning device for oil monitoring in a self-heating gas turbine, characterized in that the device comprises: Cleaning tank 1, which is equipped with liquid inlet 2; The three-way pipe includes a positive pressure filling pipe 4, a negative pressure suction pipe 12, and a connecting pipe 3. The positive pressure filling pipe 4 and the negative pressure suction pipe 12 are respectively equipped with a filling one-way valve 5 and a suction one-way valve 6. The positive pressure filling pipe 4 and the negative pressure suction pipe 12 are both connected to the cleaning tank 1, and the connecting pipe 3 is connected to a branch of the oil sampling pipeline a. A two-way pressure control valve 7 is located on the cleaning tank 1, with one end connected to the inside of the cleaning tank 1 and the other end connected to the vacuum pump 8. In negative pressure mode, the blockage in the oil sampling line a is extracted and discharged in reverse after passing through the connecting pipe 3, the suction check valve 6, the negative pressure suction pipe 12, the cleaning tank 1, the two-way pressure control valve 7, and the vacuum pump 8. In positive pressure mode, the cleaning fluid enters the cleaning tank 1, the positive pressure filling pipe 4, the filling check valve 5, the connecting pipe 3, and the oil sampling line a from the inlet 2 to clean the blockage.

[0019] It should be noted that during cleaning, the oil supply to the oil sampling line a is cut off, and the bidirectional pressure control valve 7 is switched to negative pressure mode. Specifically, the electromagnetic regulating valve 24 located behind the blockage in the delivery direction of the oil sampling line a is closed, and the electromagnetic regulating valve 25 is installed on the connecting pipe 3. The inlet 2 is closed, and the vacuum pump 8 is started to pump for about 30 seconds to reduce the pressure in the corresponding section of the oil sampling line a, the connecting pipe 3, the suction check valve 6, the negative pressure suction pipe 12, and the cleaning tank 1. The reverse airflow carries away the blockage, such as the attached sludge and particles. The blockage in the corresponding section of the oil sampling line a is sucked into the connecting pipe 3, the suction check valve 6, the negative pressure suction pipe 12, the cleaning tank 1, and the bidirectional pressure control valve 7 and then discharged, completing the reverse airflow cleaning. The bidirectional pressure control valve 7 is switched to positive pressure mode. Specifically, the vacuum pump 8 is started to supply air. After the cleaning tank 1 is pressurized, the inlet 2 is opened. The external pipeline injects cleaning fluid through the cleaning tank 1, positive pressure filling pipe 4, filling check valve 5, and connecting pipe 3 at a high flow rate of 5 m / s into the oil sampling pipeline a for flushing. Then, the electromagnetic regulating valve 24 behind the original blockage can be opened or closed. If opened, the electromagnetic regulating valve 25 can be closed and the oil outlet of the gas turbine 9 can be opened to discharge oil through the sampling mechanism 11. If closed, it can be discharged by adjusting to negative pressure mode. This allows for timely and thorough reverse cleaning of the corresponding end of the oil sampling pipeline a, ensuring the stability of the sampling mechanism 11 and improving the accuracy of oil detection in the gas turbine 9.

[0020] The starting end of the oil sampling pipeline a is connected to the oil outlet of the gas turbine 9; along the oil flow direction, the oil sampling pipeline a is also provided with a filter mechanism 10 and a sampling mechanism 11 in sequence, and the branch where the connecting pipe 3 is located is located before the filter mechanism 10.

[0021] This design, for reference Figure 1-3 In negative pressure mode, the blockages adhering to the filter mechanism 10 can be cleaned. To ensure stable delivery of oil along the oil sampling line a, a pump can be installed on the oil sampling line a.

[0022] In one embodiment, the filtration mechanism 10 includes a stainless steel filter screen 101, which is disposed on the oil sampling pipeline a. The filtration mechanism 10 further includes a first branch pipe 102, a second branch pipe 103, a partition block 105, and an annular cleaning box 104. The cleaning box 104 includes an inner ring 1040 and an outer ring 1041 that are concentrically connected. The partition block 105 and the filter screen 101 are fixed radially on the inner ring 1040. A cavity is formed between the partition block 105, the inner ring 1040, and the outer ring 1041, and the filter screen 101 is located in the cavity. The first branch pipe 102 and the second branch pipe 103 are symmetrically connected on both sides of the cleaning box 104. The cleaning box 104 is connected in series in the oil sampling pipeline a through the first branch pipe 102 and the second branch pipe 103. In the filtration state, the filter surface b of the filter screen 101 faces the first branch pipe 102.

[0023] This design, for reference Figure 2-3 When the oil sampling pipeline a is in normal sampling state, the electromagnetic regulating valve 25 on the connecting pipe 3 is closed. The oil in the oil sampling pipeline a enters the cavity through the branch pipe 102, passes through the filter surface b of the filter screen 101, and is discharged from the branch pipe 2 103. The oil continues to go to the sampling mechanism 11. Impurities in the oil are left on the filter surface b and accumulate over a long period of time to form a blockage. When sampling stops and blockage needs to be cleared, first activate the negative pressure mode to extract gas; then, the power component drives the inner ring 1040, the separator 105, and the filter screen 101 to rotate counterclockwise synchronously until the filter screen 101 completely passes through the inlet of branch pipe one 102, and the separator 105 is blocked at the inlet of branch pipe two 103. At this point, the filter screen 101 divides the cavity into a backflushing chamber and a collecting chamber c; then, activate the positive pressure mode and inject cleaning fluid into branch pipe one 102 at a high flow rate. The cleaning fluid impacts the filter screen 101. On the back side, the cleaning fluid passes through the filter screen 101 from the backwash chamber into the collection chamber c, causing the impurities that clog the mesh of the filter screen 101 and remain on the filter surface b to detach from the filter surface b and collect in the collection chamber c. After the cavity is filled with cleaning fluid, the inner ring 1040, the separator block 105 and the filter screen 101 rotate clockwise in the opposite direction. When the filter screen 101 passes through the feed of the branch pipe 102 in the opposite direction, the negative pressure mode is activated to pump out the cleaning fluid containing impurities, thus completing the cleaning. This process can be repeated multiple times.

[0024] Specifically, the switching of the two-way pressure control valve 7 to negative pressure mode refers to the process by which the pressure control valve adjusts its internal structure or control logic to make the system pressure lower than the external atmospheric pressure, thus forming a negative pressure state. The power for adjustment can be the vacuum pump 8.

[0025] In one embodiment, the filtration mechanism 10 further includes a power component disposed on the cleaning box 104, the power component driving the inner ring 1040 to rotate in the cleaning box 104 to adjust the direction and position of the filter surface b of the filter screen 101.

[0026] With this design, the power component can be a motor, the motor housing is fixed outside the cleaning box 104, and the output shaft of the motor drives the inner ring 1040 to rotate, thus realizing remote control.

[0027] In one embodiment, the device further includes a density sensor, a viscosity sensor, a moisture sensor, a temperature sensor and an oil sampling line a disposed on the sampling mechanism 11, and a flow rate sensor disposed on the oil sampling line a. The flow rate sensor is used to detect the flow rate difference of the oil before and after the oil sampling line a. If the flow rate difference exceeds the threshold, the oil sampling line a is blocked and an alarm is triggered.

[0028] In one embodiment, the cleaning tank 1 includes a tank body 121 and a cover 122. A connecting inner sleeve 123 is fixedly connected to the inner wall of the cover 122, and an external thread is provided on the outer side of the connecting inner sleeve 123. An internal thread that mates with the connecting inner sleeve 123 is provided at the opening of the tank body 121. The positive pressure filling pipe 4 is connected to the bottom of the tank body 121, and the negative pressure suction pipe 12 is connected to the top of the tank body 121.

[0029] In one embodiment, the filtration mechanism 10 further includes a paper filter element and a polytetrafluoroethylene filter membrane sequentially arranged on the oil sampling pipeline a, wherein the paper filter element is located between the branch pipe 103 and the polytetrafluoroethylene filter membrane; and an electromagnetic regulating valve 24 is provided on the oil sampling pipeline a, wherein the electromagnetic regulating valve 24 is located between the branch pipe 103 and the polytetrafluoroethylene filter membrane.

[0030] This design enables three-stage filtration: filter screen 101, paper filter element, and polytetrafluoroethylene filter membrane, resulting in more thorough filtration and preventing clogging of the sampling mechanism 11.
