Description

Technical Field

[0001] The embodiments of this specification belong to the technical field of oil depot transmission pipeline technology, and particularly relate to a filter sediment discharge detection system and method. Background Art

[0002] In order to meet the sedimentation detection needs of filters in oil depot transfer pipelines, it is necessary to regularly check the quality of the oil in the filter sedimentation tank. Oil with qualified quality can be reused, while oil with unqualified quality needs to be discharged and degraded.

[0003] Existing methods for detecting sedimentation from filters in oil depot transfer pipelines typically utilize electric recovery pumps and associated electrical equipment to transport the inspected sediment. Because oil depot transfer pipelines are primarily located in explosion-proof areas, this method of transporting sediment using pumps and associated electrical equipment presents a need to mitigate operational risks and potential safety hazards. Summary of the Invention

[0004] The embodiments of the present disclosure provide a filter sediment discharge detection system and method.

[0005] In a first aspect of an embodiment of the present disclosure, a sediment discharge detection system for a filter is provided. The system includes a recovery line and an injector. The recovery line is arranged between the main line and the filter in parallel with the main line, and the filter is connected to an oil storage device, which is used to store qualified sediment oil products output by the filter. The injector includes a first inlet connected to the recovery line through a first control valve, a second inlet connected to the oil storage device, and a diffuser connected to the filter inlet. The first control valve is arranged between the first inlet and the recovery line to generate a negative pressure in the injector for sucking the sediment oil products in the oil storage device into the injector through the second inlet.

[0006] In a second aspect of an embodiment of the present disclosure, a filter sediment discharge detection method is provided, which is applied to the filter sediment discharge detection system disclosed in the first aspect. The method includes determining whether the sedimented oil product output by the filter has passed the test when there is accumulated oil product stored in the oil storage device. In response to determining that the sedimented oil product has passed the test, based on the similarity between the gas chromatography analysis results of the accumulated oil product and the gas chromatography analysis results of the sedimented oil product, it is determined whether the accumulated oil product is consistent with the sedimented oil product. In response to determining that the accumulated oil product is consistent with the sedimented oil product, the sedimented oil product is output to the oil storage device, and the first control valve is controlled to open.

[0007] In a third aspect of an embodiment of the present disclosure, a computer program product is provided, comprising a computer program, which, when executed by a processor, implements the filter sediment discharge detection method disclosed in the second aspect.

[0008] In a fourth aspect of an embodiment of the present disclosure, an electronic device is provided, comprising one or more processors and a memory associated with the one or more processors, the memory being used to store program instructions, which, when read and executed by the one or more processors, execute the filter sedimentation detection method disclosed in the second aspect.

DETAILED DESCRIPTION

[0011] To make the purpose, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0012] The terms "including" and "having" and any variations thereof in this specification and claims and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or apparatuses. Depending on the context, the word "if" as used herein may be interpreted as "at..." or "when..." or "in response to determining" or "in response to detecting".

[0013] As mentioned above, the current method for draining and testing filters in oil depot transfer pipelines typically involves draining the filter sediment into a closed-circuit sampler. The sediment in the closed-circuit sampler is then manually inspected for quality. If the sediment passes the inspection, an electric recovery pump and its associated electrical equipment are used to extract the sediment from the closed-circuit sampler and recycle it to the main storage and transportation system. If the sediment fails the inspection, the bypass ball valve at the rear end of the closed-circuit sampler drains the sediment into a small bucket and manually transports it to a waste oil tank for degradation. However, since oil depot transfer pipelines are primarily located in explosion-proof areas, designing electric recovery pumps and their associated electrical equipment would result in an excessive number of electrical devices within the explosion-proof area. Furthermore, this electrical equipment presents a certain explosion risk, which can lead to high equipment operation risks during the filter drain and testing process, and can also pose safety hazards.

[0014] Based on this, embodiments of the present disclosure provide a filter sediment discharge detection system and method, wherein the system includes a recovery line and an ejector. The recovery line is arranged in parallel with the main line between the main line and the filter. The filter is connected to an oil storage device, which is used to store qualified sedimented oil output by the filter. The ejector includes a first inlet connected to the recovery line via a first control valve, a second inlet connected to the oil storage device, and a diffuser connected to the filter inlet. The first control valve is arranged between the first inlet and the recovery line to generate negative pressure within the ejector, which is used to draw sedimented oil in the oil storage device into the ejector through the second inlet.

[0015] Through this transportation structure composed of the ejector, recovery pipeline, oil storage device and first control valve, the electrical equipment in the explosion-proof area can be reduced, and the types of electrical equipment used are relatively low-risk. This not only reduces the equipment risks and safety hazards caused by excessive electrical equipment, but also makes the oil transportation method more energy-saving and environmentally friendly.

[0016] See also Figure 1 , Figure 1 The schematic diagram of the structure of the filter sedimentation detection system of some embodiments of the present disclosure is shown. Figure 1As shown, the filter sediment discharge detection system 100 may include a main pipeline 101, a main line 102, a filter 103, a recovery line 104, a first control valve 105, an ejector 106, and an oil storage device 107. The main pipeline 101 and the main line 102 may serve as an oil product transportation pipeline and may be disposed together with the filter 103 in a main storage and transportation system of an oil depot transfer pipeline. The main storage and transportation system may transport filtered oil to the filter 103 via the main pipeline 101 and the main line 102. The filter 103 may filter the filtered oil and transport the clean oil obtained by the filtration to storage and transportation equipment in the main storage and transportation system, such as an oil storage tank for storing oil. Sediment discharged from the filtered oil may also be stored for quality inspection by manual labor or a detection device. Once the quality of the sediment is determined to be acceptable, the qualified sediment may be discharged to the oil storage device 107. Here, the filter 103 may also be provided with an outlet for discharging the clean oil obtained after the filtration process, and a ball valve may also be provided between the outlet and the storage and transportation equipment to achieve transportation control or flow rate control of the clean oil. Of course, in the embodiment of the present disclosure, the outlet may also be connected to other equipment in the main storage and transportation system, but is not limited to this.

[0017] It is understood that the precipitated oil discharged from filter 103 may contain impurities or a small amount of incompletely separated oil mixture. When performing a quality inspection on the precipitated oil, for example, manually extracting the precipitated oil from filter 103 and inspecting it visually or using a chemical water detector diaphragm to determine whether it contains impurities, free water, or normal color is necessary. If any of the following conditions are detected, the precipitated oil is deemed unqualified and filter 103 may be controlled to discharge the precipitated oil through a transport pipeline to a waste oil tank for degradation. If the precipitated oil is detected to be free of impurities and free water and to have a normal color, the precipitated oil is deemed qualified and filter 103 may be controlled to discharge the precipitated oil to an oil storage device 107. Oil storage device 107 may be understood as a tank having a discharge port, as is well known in the art, for discharging the precipitated oil through the discharge port to ejector 106. Of course, some embodiments of the present disclosure may also utilize a detection device to perform quality inspection on the precipitated oil. The detection device may be a device well known in the art for oil quality inspection (such as a moisture meter, etc.), which will not be described in detail here.

[0018] The main pipeline 101, the recovery pipeline 104, the first control valve 105, and the ejector 106 can serve as another oil product transportation pipeline and be arranged together with the filter 103 in the main storage and transportation system of the oil depot transfer pipeline. In addition to transporting the filtered oil product to the filter 103 through the main pipeline 101 and the main pipeline 102, the main storage and transportation system can also transport the mixed oil obtained by mixing the filtered oil product with the qualified precipitated oil product to the filter 103 through the main pipeline 101, the recovery pipeline 104, the first control valve 105, and the ejector 106 when the first control valve 105 is opened. Here, the first control valve 105 can be understood as an electric control valve well known in the art (of course, it can also be a manual control valve or other type of valve), which can be opened or closed according to a preset automatic control program or manual control. Of course, it can also be connected to a controller to achieve switching between the open and closed states by receiving instructions, but the present invention is not limited to this. The injector 103 is provided with a first inlet connected to the recovery line 104 through the first control valve 105, a second inlet connected to the oil storage device 107 and a diffuser connected to the inlet of the filter 103. When the first control valve 105 is opened, the first inlet can be used to receive the filtered oil output by the recovery line 104, and the first inlet can be used to provide a negative pressure to the second inlet when the first control valve 105 is opened to receive the qualified precipitated oil output by the oil storage device 107 through the second inlet, and the mixed oil obtained by mixing the filtered oil and the qualified precipitated oil can be output to the filter 103 through the diffuser.

[0019] It should be noted that the injector 106 of some embodiments of the present disclosure can also utilize the open state of the first control valve 105 to transport the filtered oil on the main pipeline 101 to the filter 103 through the recovery pipeline 104, the first control valve 105 and the injector 106 when no precipitated oil is produced in the filter 103, that is, the rapid transportation of the filtered oil is achieved through dual channels, and after the qualified precipitated oil is stored in the filter 103, the qualified precipitated oil can be transported to the injector through the oil storage device 107.

[0020] Through this transportation structure composed of the ejector, recovery pipeline, oil storage device and first control valve, the electrical equipment in the explosion-proof area can be reduced, and the types of electrical equipment used are relatively low-risk. This not only reduces the equipment risks and safety hazards caused by excessive electrical equipment, but also makes the oil transportation method more energy-saving and environmentally friendly.

[0021] See also Figure 2 , Figure 2 The schematic diagram of the structure of the ejector in the filter sedimentation detection system of some embodiments of the present disclosure is shown. Figure 2As shown, the structure of the ejector 200 may include an inlet section 201, a mixing section 202, and a diffuser section 203, which are sequentially connected between the first inlet and the diffuser. The inlet section 201 is divided into a power chamber for receiving filtered oil output from the recovery line through the first inlet, a power nozzle 204 for outputting the filtered oil in the power chamber to the mixing section 202, and an intake chamber for receiving qualified sediment oil output from the oil storage device through the second inlet. Figure 2 The illustrated power nozzle structure of ejector 200 reduces the cross-sectional area of the filtered oil in the power chamber and increases its flow rate as it passes through power nozzle 204, thereby causing power nozzle 204 to deliver the filtered oil as a high-speed jet. This high-speed jet of filtered oil creates a Venturi effect around the suction chamber, creating a vacuum or low-pressure environment between the suction chamber and the mixing section. This negative pressure causes the qualified sedimented oil stored in the oil storage device connected to the suction chamber to be drawn into the suction chamber at a low speed.

[0022] The mixing section 202 can be understood as a mixing chamber including an input end and an output end, wherein the inner diameter of the mixing chamber is smaller than the inner diameter of the input end and smaller than the inner diameter of the output end (i.e., the inner diameter of the mixing section 202 is smaller than the inner diameters of the inlet section 201 and the diffusion section 203), so that when the above-mentioned power nozzle 204 outputs the filtered oil product in a high-speed jet state to the input end, and the suction chamber outputs the low-speed qualified sedimented oil product to the input end, the mixing chamber is used to perform turbulent mixing of the filtered oil product in a high-speed jet state and the low-speed qualified sedimented oil product, that is, the filtered oil product in a high-speed jet state transfers momentum to the low-speed qualified sedimented oil product, thereby making the flow rate of the mixed oil product tend to be balanced.

[0023] Since the inner diameter of the mixing section 202 is smaller than that of the diffuser section 203, and the inner diameter of the diffuser section 203 gradually increases in the direction from the mixing section 202 to the filter, the cross-sectional area of the mixed oil product output from the mixing section gradually increases and the flow rate gradually decreases after entering the diffuser section. At this time, the kinetic energy is converted into pressure energy, thereby allowing the mixed oil product to enter the filter at a relatively normal pressure (this normal pressure can be understood as being less than the pressure of the filtered oil product in a high-speed jet state output by the power nozzle, and greater than the pressure of the low-speed qualified sedimentation oil product output by the suction chamber).

[0024] Through the inlet section 201, mixing section 202 and diffusion section 203 structure designed for the ejector, qualified precipitated oil can be sucked into the suction chamber by utilizing the negative pressure generated by the power nozzle when outputting filtered oil without the need for an electric recovery oil pump and its related electrical equipment, and mixed with the filtered oil into the filter. The entire process only involves the state control of the first control valve and does not require an electric recovery oil pump and its related electrical equipment, thereby reducing equipment operation risks and safety hazards, and being more environmentally friendly and efficient.

[0025] In some embodiments, the sediment discharge detection system of the filter further includes a closed-circuit sampler, and the filter in the sediment discharge detection system of the filter further includes a sedimentation tank connected to the closed-circuit sampler.

[0026] In addition to the aforementioned main pipeline, main line, filter, recovery line, first control valve, ejector, and oil storage device, the filter sedimentation detection system of some embodiments of the present disclosure also includes a closed-circuit sampler. This closed-circuit sampler allows for efficient and accurate quality inspection of the sedimented oil after the filter discharges it. The filter's sedimentation tank can store sedimented oil discharged from the filtered oil. When the filter is in sedimentation mode, the filter can transfer the sedimented oil in the sedimentation tank to the closed-circuit sampler. It is understood that the filter can operate in two modes: a filtration mode and a sedimentation mode. In the filtration mode, the filter can filter the filtered oil to produce clean oil and transfer sedimented oil discharged from the filtered oil to the sedimentation tank. In the sedimentation mode, the filter can continuously filter the filtered oil while applying pressure to the sedimentation tank to transfer the sedimented oil to the closed-circuit sampler. The functions performed by the filter are conventional techniques for filters in the art and are not detailed here.

[0027] It should be noted that before the filter processes the filtered oil that needs to be drained and tested, there may be accumulated oil in the filter's sedimentation tank from other oils discharged during filtration. In this case, this accumulated oil needs to be transferred to the oil storage device in advance, and the oil storage device will be used to drain the accumulated oil. Of course, when draining the accumulated oil, the filter's sedimentation tank and oil storage device can also be cleaned manually or automatically through a control program to avoid oil mixing.

[0028] The closed-circuit sampler may include a recovery port for recovering qualified precipitated oil products when the precipitated oil products pass the test. The recovery port is connected to the oil storage device to output the qualified precipitated oil products to the oil storage device. Of course, the closed-circuit sampler may also include a discharge port for discharging unqualified precipitated oil products when the precipitated oil products fail the test, so that the unqualified precipitated oil products can be output to the waste oil tank for degradation. It is understandable that the closed-circuit sampler may also include a support base, a glass barrel disposed on the support base for storing the precipitated oil products, and a sampling cover disposed on the top of the glass barrel. The glass barrel may be provided with a discharge port connected to the sedimentation tank, and the above-mentioned recovery port and discharge port may be disposed on the glass barrel. Here, when conducting a quality inspection on the precipitated oil in the closed-circuit sampler, for example, manually, the person can first inspect the appearance of the precipitated oil through a glass bottle to determine whether there are impurities and whether the color of the oil is normal. Then, after confirming that there are no impurities and the color of the oil is normal, an appropriate amount of precipitated oil is extracted from the glass barrel through the sampling cover and a chemical water detector diaphragm is used to detect moisture. The quality of the precipitated oil is determined to be qualified after the detected moisture content meets the requirements.

[0029] See also Figure 3 , Figure 3 Another structural diagram of the filter sedimentation detection system of some embodiments of the present disclosure is shown. Figure 3 As shown, the filter sediment discharge detection system 300 may include a main line 301, a main line 302, a filter 303, a recovery line 304, a first control valve 305, an ejector 306, an oil storage device 307, and a closed-circuit sampler 308. Here, the filter 303 is provided with a sedimentation tank. When the filter 303 has not yet processed the filtered oil that requires sedimentation detection, the stored oil can be output to the oil storage device 307 and discharged through the oil storage device 307. Furthermore, when the filter 303 is in sedimentation mode, the sediment discharged from the filtered oil can be output to the closed-circuit sampler 308. After the closed-circuit sampler 308 determines that the sedimented oil is of acceptable quality, the first control valve is controlled to be in an open state, so that the oil storage device 307 outputs the qualified sedimented oil to the ejector 306. Of course, in some embodiments of the present disclosure, the closed-circuit sampler 308 may further discharge the unqualified precipitated oil through the discharge port and perform a degradation treatment after determining that the precipitated oil is of unqualified quality.

[0030] In some embodiments, the sedimentation discharge detection system of the filter also includes a second control valve arranged between the sedimentation tank and the closed-circuit sampler. The second control valve is opened when the filter is in the sedimentation discharge mode to connect the pipeline between the sedimentation tank and the closed-circuit sampler; and the second control valve is closed when the filter is not in the sedimentation discharge mode to block the pipeline between the sedimentation tank and the closed-circuit sampler.

[0031] In addition to the aforementioned main pipeline, main line, filter, recovery line, first control valve, ejector, oil storage device, and closed-circuit sampler, the filter sediment discharge detection system of some embodiments of the present disclosure further includes a second control valve. The second control valve can be understood as an electrically controlled valve (or a manually controlled valve or other type of valve) as is well known in the art. There can be one or more second control valves, which can be opened or closed according to a preset automatic control program or manual control. Of course, they can also be connected to a controller to switch between the open and closed states by receiving instructions. For example, the second control valve can include a discharge ball valve, an automatic reset valve, and an inlet ball valve, which are sequentially arranged between the sedimentation tank and the closed-circuit sampler. The discharge ball valve can be opened to allow manual or cleaning equipment to clean residues in the pipeline before the sedimentation tank discharges the sedimentation oil to the closed-circuit sampler, and closed to ensure the sealing of the pipeline between the sedimentation tank and the closed-circuit sampler. The automatic reset valve and the inlet ball valve can be opened or closed to achieve precise control of the delivery of the sedimentation oil to the closed-circuit sampler.

[0032] It is understood that when the filter is in the discharge and sedimentation mode, the second control valve can be opened for a specified period of time according to a preset automatic control program or manual control, so as to connect the pipeline between the sedimentation tank and the closed-circuit sampler after the settled oil in the sedimentation tank reaches a first requirement, thereby ensuring the continuous and stable output of the settled oil to the closed-circuit sampler. Here, the first requirement can be, for example, that the quality of the settled oil reaches a specified quality threshold, which can be, but is not limited to, the quality of the settled oil measured by a quality detection device provided in the sedimentation tank; or the specified requirement can also be that the flow rate of the settled oil discharged from the filter reaches a specified flow rate threshold, which can be, but is not limited to, the flow rate of the settled oil measured by a flow rate detection device provided in the sedimentation tank, and is not limited to this.

[0033] Of course, the second control valve can also be closed according to a preset automatic control program or manual control when the filter is not in the drainage mode, for example, when the filter is in the filtering mode or stopped, so as to block the pipeline between the sedimentation tank and the closed-circuit sampler after the settled oil in the closed-circuit sampler reaches a second requirement, thereby ensuring the efficiency and accuracy of the quality inspection of the settled oil in the closed-circuit sampler. Here, the second requirement can be, for example, that the quality of the settled oil in the closed-circuit sampler reaches a quality threshold corresponding to the oil inspection. The quality of the settled oil can be, but is not limited to, collected by a quality detection device provided in the closed-circuit sampler, or the ratio between the volume of the settled oil in the closed-circuit sampler and the volume of the cavity in the closed-circuit sampler exceeds a preset ratio threshold (which can be inferred by manual visual inspection), and is not limited to these.

[0034] In some embodiments, the sedimentation detection system of the filter also includes a third control valve arranged between the sedimentation tank and the oil storage device. The third control valve opens when there is accumulated oil in the sedimentation tank to connect the pipeline between the sedimentation tank and the oil storage device, and discharges the accumulated oil in the sedimentation tank to the oil storage device; and the third control valve closes when there is no accumulated oil in the sedimentation tank to block the pipeline between the sedimentation tank and the oil storage device.

[0035] In addition to the main pipeline, main line, filter, recovery line, first control valve, injector, oil storage device, and closed-circuit sampler mentioned above, the filter sedimentation detection system of some embodiments of the present disclosure also includes a third control valve. The third control valve can be understood as an electric control valve well known in the art (it can also be a manual control valve or other type of valve). There can be one or more of the third control valves, which can be opened or closed according to a preset automatic control program or manual control. Of course, it can also be connected to a controller to switch between the open and closed states by receiving instructions. For example, the third control valve can include a discharge ball valve, an automatic reset valve, and a gate valve, which are sequentially arranged between the sedimentation tank and the oil storage device. The discharge ball valve can be opened to allow manual or cleaning equipment to clean the residue in the pipeline when the sedimentation tank has accumulated oil, and closed to ensure the sealing of the pipeline between the sedimentation tank and the oil storage device. The automatic reset valve and gate valve can be opened to discharge the accumulated oil in the sedimentation tank when the sedimentation tank is outputting the accumulated oil to the oil storage device.

[0036] It is understood that the presence of accumulated oil in the settling tank can be determined manually or through a preset automatic control program. For example, before the filter processes filtered oil requiring sedimentation testing, the presence of accumulated oil in the settling tank can be automatically determined using the detection value of a quality detection device located in the settling tank, without limitation. When accumulated oil is present in the settling tank, the third control valve can be opened according to a preset automatic control program or manual control to connect the pipeline between the settling tank and the oil storage device, thereby enabling the discharge of accumulated oil in the settling tank and preventing oil mixing. Of course, if it is determined manually or through a preset automatic control program that no accumulated oil is present in the settling tank, the third control valve can be closed to block the pipeline between the settling tank and the oil storage device, thereby preventing the subsequent discharge of settled oil from the filter from passing through the settling tank to the oil storage device. Here, after the settling tank is cleared of accumulated oil, it can be cleaned manually or with a cleaning device to ensure the accuracy of the quality inspection of the settled oil.

[0037] See also Figure 4 , Figure 4 Another structural diagram of the filter sedimentation detection system of some embodiments of the present disclosure is shown. Figure 4As shown, the filter sediment discharge detection system 400 may include a main pipeline 401, a main line 402, a filter 403, a recovery line 404, a first control valve 405, an ejector 406, an oil storage device 407, a closed-circuit sampler 408, a second control valve 409, and a third control valve 410. The second control valve 409 may be an inlet ball valve, as is well known in the art, disposed between the sedimentation tank of the filter 403 and the closed-circuit sampler 408. A discharge ball valve and an automatic reset valve are also disposed sequentially between the sedimentation tank of the filter 403 and the second control valve 409. The third control valve 410 may be a gate valve, as is well known in the art, disposed between the sedimentation tank of the filter 403 and the oil storage device 407. A discharge ball valve and an automatic reset valve are also disposed sequentially between the sedimentation tank of the filter 403 and the third control valve 410.

[0038] It is understood that when oil accumulates in the sedimentation tank of filter 403, the drain ball valve, automatic reset valve, and third control valve can be controlled to connect the pipeline between the sedimentation tank of filter 403 and oil storage device 407, allowing the accumulated oil in the sedimentation tank to be discharged to oil storage device 407, where the accumulated oil can be discharged and processed. When the sedimentation tank of filter 403 is free of accumulated oil, the drain ball valve, automatic reset valve, and third control valve can be controlled to block the pipeline between the sedimentation tank of filter 403 and oil storage device 407, allowing filter 403 to process the filtered oil that needs to be discharged and tested. When filter 403 is in sedimentation mode, the drain ball valve, automatic reset valve, and second control valve can be controlled to connect the pipeline between the sedimentation tank of filter 403 and closed-circuit sampler 408, allowing the accumulated oil in the sedimentation tank to be discharged to closed-circuit sampler 408. Until the filter 403 is not in the drainage mode, the pipeline between the sedimentation tank of the filter 403 and the closed-circuit sampler 408 can be blocked by controlling the discharge ball valve, the automatic reset valve and the second control valve to ensure the quality inspection efficiency and accuracy of the precipitated oil in the closed-circuit sampler 408.

[0039] Of course, in some embodiments of the present disclosure, a control valve may also be provided between the closed-circuit sampler 408 and the oil storage device 407, so that when the quality of the precipitated oil in the closed-circuit sampler 408 is qualified, the control valve can be controlled to be in an open state through manual control or a preset automatic control program, thereby outputting the qualified precipitated oil in the closed-circuit sampler 408 to the oil storage device 407, and when the first control valve 405 is in an open state, the qualified precipitated oil in the oil storage device 407 is mixed with the filtered oil by the negative pressure provided by the ejector 406 to obtain a mixed oil, which is then output to the filter 403.

[0040] In some embodiments of the present disclosure, a control valve may also be provided between the oil storage device 407 and the second inlet of the injector 406, so that when the first control valve 405 is in the open state, the control valve can be controlled to be in the open state through manual control or a preset automatic control program, so as to effectively control the flow rate of qualified precipitated oil entering the injector 406, thereby ensuring the stability of the mixed oil generated in the injector.

[0041] In some embodiments of the present disclosure, a control valve may also be provided between the main line 402 and the filter 403, so that when the filter is in the filtering mode, the control valve can be controlled to be in an open state by manually controlling a preset automatic control program, so as to effectively control the flow rate of the filtered oil entering the filter 403, thereby ensuring the filtering efficiency of the filter 403 on the filtered oil.

[0042] In some embodiments, the sedimentation detection system of the filter also includes a gas chromatography device, which obtains gas chromatography analysis results of the accumulated oil when the oil storage device stores accumulated oil; and when the gas chromatography device stores precipitated oil in the sedimentation tank of the filter, it obtains gas chromatography analysis results of the precipitated oil.

[0043] In addition to the main pipeline, main line, filter, recovery line, first control valve, injector and oil storage device mentioned above (of course, it can also include a closed-circuit sampler, a second control valve and a third control valve), the sedimentation detection system of the filter of some embodiments of the present disclosure also includes a gas chromatography device. The gas chromatography device can be but is not limited to a gas chromatograph analyzer well known in the art. By respectively obtaining the gas chromatography analysis results of the precipitated oil product and the gas chromatography analysis results of the stored oil product, it is determined whether the oil quality of the stored oil product is consistent with that of the precipitated oil product, thereby ensuring the utilization rate of the stored oil product and the transportation efficiency of the precipitated oil product.

[0044] Here, after the filter's sedimentation tank discharges the accumulated oil into the oil storage device, a gas chromatography device can be controlled manually or through a preset automatic control program to analyze the accumulated oil in the oil storage device to obtain the content of different components in the accumulated oil, i.e., the gas chromatography analysis results of the accumulated oil. It should be noted that the analysis settings of the gas chromatography device in some embodiments of the present disclosure are conventional technical means in the art and are not detailed here.

[0045] Of course, when the filter's sedimentation tank contains precipitated oil discharged from the filtered oil, the gas chromatography device can be controlled manually or by a preset automatic control program to analyze the precipitated oil in the sedimentation tank to obtain the content of different components in the precipitated oil, i.e., the gas chromatography analysis results of the precipitated oil. It is understood that when the filter's sedimentation detection system also includes a closed-circuit sampler, the precipitated oil in the sedimentation tank can also be output to the closed-circuit sampler to determine whether the precipitated oil is qualified. The present invention is not limited to this.

[0046] In some embodiments, the sediment discharge detection system of the filter also includes a flow rate detection device arranged between the filter and the closed-circuit sampler. The flow rate detection device obtains the flow rate detection value of the precipitated oil when the filter outputs the precipitated oil to the closed-circuit sampler.

[0047] In addition to the main pipeline, main line, filter, recovery line, first control valve, injector and oil storage device mentioned above (of course, it can also include a closed-circuit sampler, a second control valve and a third control valve), the sediment discharge detection system of the filter in some embodiments of the present disclosure also includes a flow rate detection device. The flow rate detection device can be, but is not limited to, a flow meter well known in the art. By obtaining the flow rate detection value of the sedimented oil transported to the closed-circuit sampler in real time, it can determine whether the current transportation flow rate of the sedimented oil needs to be adjusted, thereby ensuring the accuracy of the quality inspection of the sedimented oil.

[0048] Here, when the sedimentation tank outputs the precipitated oil to the closed-circuit sampler, if the flow rate detection value collected by the flow rate detection device is large (for example, exceeding the preset flow rate threshold), it indicates that the precipitated oil is prone to gas-liquid mixing due to turbulence in the closed-circuit sampler, thereby affecting the quality inspection of the precipitated oil. At this time, it is necessary to adjust the flow rate of the precipitated oil output to the closed-circuit sampler, for example but not limited to providing a control valve between the sedimentation tank and the closed-circuit sampler, and adjusting the valve opening or valve opening time of the control valve to avoid turbulence of the precipitated oil in the closed-circuit sampler.

[0049] See also Figure 5 , Figure 5 An example environment diagram of a filter sedimentation detection method according to some embodiments of the present disclosure is shown. Figure 5As shown, an example environment 500 of a filter sediment discharge detection method may include a main pipeline 501, a main line 502, a filter 503, a recovery line 504, a first control valve 505, an ejector 506, an oil storage device 507, and a controller 508. The main pipeline 501 and the main line 502 may serve as an oil product transportation pipeline and may be disposed together with the filter 503 in a main storage and transportation system of an oil depot transfer pipeline. The main storage and transportation system may transport filtered oil to the filter 503 via the main pipeline 501 and the main line 502. The filter 503 may filter the filtered oil and transport the clean oil obtained by the filtration to storage and transportation equipment in the main storage and transportation system, such as an oil storage tank for storing oil. The filter 503 may also store and process the sediment discharged from the filtered oil and, after determining that the sediment is of qualified quality, discharge the qualified sediment to the oil storage device 507. In addition, the main pipeline 501, the recovery pipeline 504, the first control valve 505 and the injector 506 can serve as another oil transportation pipeline, and be arranged together with the filter 503 in the main storage and transportation system of the oil depot transfer pipeline. In addition to transporting the filtered oil to the filter 503 through the main pipeline 501 and the main line 502, the main storage and transportation system can also transport the mixed oil obtained by mixing the filtered oil with the qualified precipitated oil to the filter 103 through the main pipeline 501, the recovery pipeline 504, the first control valve 505 and the injector 506 when the first control valve 505 is opened.

[0050] The controller 508 may be, but is not limited to, a programmable logic controller known in the art. The controller 508 may establish a communication connection with the filter 503 to control the operating mode of the filter 503. For example, when the main storage and transportation system transports the filtered oil to the main pipeline 501, the controller 508 may control the filter 503 to operate in a filtering mode so that the filter 503 filters the filtered oil. Furthermore, when there is precipitated oil in the sedimentation tank of the filter 503, the controller 508 may control the filter 503 to switch to a drainage mode so that the precipitated oil in the sedimentation tank is output to the oil storage device 507. Of course, the controller 508 may also control the filter 503 to stop operating after completing the drainage detection of the filtered oil to reduce energy consumption, but this will not be described in detail here.

[0051] The controller 508 can also establish a communication connection with the oil storage device 507. The oil storage device 507 can be provided with an electrically controlled output valve and a discharge valve, so that when the quality of the precipitated oil is qualified, the controller 508 sends an instruction to the oil storage device 507 to output the precipitated oil from the oil storage device 507 to the injector 506 by putting the output valve in an open state (the discharge valve is in a closed state at this time); and when the quality of the precipitated oil is unqualified, the controller 508 can also send an instruction to the oil storage device 507 to discharge the precipitated oil from the discharge valve by putting the discharge valve in an open state (the output valve is in a closed state at this time) and perform degradation treatment.

[0052] The controller 508 can also establish a communication connection with the first control valve 505, which can be an electric control valve well known in the art. When the quality of the precipitated oil is qualified, the controller 508 sends an instruction to the first control valve, and by putting the control valve in an open state, the filtered oil on the main pipeline 501 can also enter the injector 506, and utilize the negative pressure provided when the filtered oil enters the injector 506 to suck the qualified precipitated oil output by the oil storage device 507 into the injector 506; and when the quality of the precipitated oil is unqualified, the controller 508 sends an instruction to the first control valve, and by putting the control valve in a closed state, unqualified precipitated oil is prevented from entering the injector 508. Of course, if the sediment discharge detection system of the filter also includes the second control valve, third control valve and other control valves mentioned above, the controller 508 can also establish a communication connection with the second control valve, the third control valve and other control valves. The second control valve, the third control valve and other control valves here can all be electric control valves well known in the art, so that they can be in an open or closed state according to the instructions issued by the controller 508, thereby ensuring the normal execution of the sediment discharge detection process of the filtered oil.

[0053] In addition, if the filter's sediment discharge detection system also includes the flow rate detection device mentioned above, the controller 508 can also establish a communication connection with the flow rate detection device. When the sedimentation tank of the filter 503 outputs the filtered oil to the oil storage device 507, the controller 508 can send instructions to the flow rate detection device to obtain the flow rate detection value of the sedimentation oil transported to the closed-circuit sampler in real time, and determine whether the current transportation flow rate of the sedimentation oil needs to be adjusted based on the flow rate detection value and the preset flow rate threshold. Here, if the current transportation flow rate of the sedimentation oil needs to be adjusted, the controller 507 can also send instructions to the control valve provided between the sedimentation tank of the filter 503 and the oil storage device 507. At this time, the instruction can be used to adjust the valve opening or valve opening time of the control valve, and is not limited to this.

[0054] If the filter sedimentation detection system also includes the aforementioned gas chromatography device, the controller 508 can also establish a communication connection with the gas chromatography device. After the sedimentation tank of the filter 503 outputs the accumulated oil product to the oil storage device 507, the controller 508 can issue a command to the gas chromatography device to control the gas chromatography device to analyze the accumulated oil product in the oil storage device 507 to obtain the content of different components in the accumulated oil product, that is, the gas chromatography analysis result of the accumulated oil product. Furthermore, when the sedimentation oil product discharged from the filtered oil product is stored in the sedimentation tank of the filter 503, the controller 508 can also issue a command to control the gas chromatography device to analyze the sedimentation oil product in the sedimentation tank to obtain the content of different components in the sedimentation oil product, that is, the gas chromatography analysis result of the sedimentation oil product. By analyzing the gas chromatography analysis results of the accumulated oil product and the sedimentation oil product, it can be determined whether the oil quality of the accumulated oil product and the sedimentation oil product is consistent.

[0055] It is understandable that manual determination of whether the quality of the precipitated oil product is qualified is easily affected by objective factors, resulting in inaccurate determination. In some embodiments of the present disclosure, in order to ensure the accuracy of determining whether the quality of the precipitated oil product is qualified, the controller 508 may perform the following steps to determine whether the quality of the precipitated oil product is qualified: Determine whether the appearance of the sediment oil output from the filter is normal; In response to determining that the appearance of the precipitated oil product is normal, determining reagent parameters of the reaction reagent based on a reaction result of the precipitated oil product and the reaction reagent; determining whether the water content of the precipitated oil product is normal based on reagent parameters of the reaction reagent and oil parameters of the precipitated oil product; and In response to determining that the water content of the precipitated oil product is normal, the precipitated oil product is determined to be qualified.

[0056] Here, the controller 508 can control the sedimentation tank of the filter 503 to output the precipitated oil to the closed-circuit sampler, and analyze the images captured by the closed-circuit sampler via the image acquisition device to determine whether the appearance of the precipitated oil output by the filter 503 is normal, that is, to determine whether the precipitated oil contains impurities, obvious oil-water stratification, and whether the oil color is normal. It is understood that the closed-circuit sampler can be a structure for oil sampling known in the art. For example, in one or more embodiments of the present disclosure, the closed-circuit sampler can include a support base, a glass barrel disposed on the support base for storing the precipitated oil, and a sampling cover disposed on the top of the glass barrel. The glass barrel can be provided with a discharge port connected to the sedimentation tank, a recovery port connected to the oil storage device, and a discharge port. The image acquisition device can be, but is not limited to, an industrial camera well known in the art. By establishing a communication connection with the controller 508, it can acquire an oil image containing the precipitated oil and the closed-circuit sampler after receiving an instruction from the controller 508. At this time, the controller 508 can perform image analysis and processing on the oil image, for example, through feature contour recognition and color comparison to determine whether the precipitated oil contains impurities, obvious oil-water stratification, and whether the oil color is normal.

[0057] When the precipitated oil product is free of impurities and obvious oil-water stratification, and the oil product has a normal color, the controller 508 may determine that the appearance of the precipitated oil product is normal. To further determine whether the water content in the precipitated oil product exceeds the standard, the controller 508 may control the oil extraction device to extract a specified weight of the precipitated oil product from the closed-circuit sampler and drip a reaction reagent into the fixed amount of precipitated oil product. The reagent parameters of the reaction reagent are determined based on the reaction results of the precipitated oil product and the reaction reagent. Here, the reaction reagent may be, but is not limited to, an organic base and solvent containing iodine and sulfur dioxide, which can react with the water in the precipitated oil product. The controller 508 may determine whether the reaction reagent has completely reacted with the water in the precipitated oil product by detecting the change in current when the precipitated oil product and the reaction reagent are reacted. When it is determined that the reaction reagent has completely reacted with the water in the precipitated oil product, the volume of the reaction reagent dripped at this time is used as the reagent parameter of the reaction reagent.

[0058] Of course, if the precipitated oil contains impurities, obvious oil-water stratification, or abnormal oil color, the controller 508 can determine that the appearance of the precipitated oil is abnormal, and then control the closed-circuit sampler to discharge the unqualified precipitated oil.

[0059] Next, after determining the reagent parameters of the reaction reagent, the controller 508 can calculate the moisture content of the precipitated oil based on the reagent parameters, the standard concentration of the reaction reagent, and the oil parameters of the precipitated oil. The standard concentration of the reaction reagent can be determined based on the type of reaction reagent, and the oil parameters of the precipitated oil can be the weight of the precipitated oil extracted from the closed-circuit sampler. To calculate the moisture content of the precipitated oil, the controller 508 first calculates the product of the reagent parameters and the standard concentration of the reaction reagent, then calculates the ratio of this product to the oil parameters of the precipitated oil, and uses this ratio as the moisture content of the precipitated oil.

[0060] Next, if the controller 508 detects that the moisture content of the precipitated oil does not exceed a preset moisture threshold, it determines that the moisture content of the precipitated oil is normal, i.e., determines that the quality of the precipitated oil is acceptable. Furthermore, if the controller 508 detects that the moisture content of the precipitated oil exceeds a preset moisture threshold, it determines that the moisture content of the precipitated oil is abnormal, i.e., determines that the quality of the precipitated oil is unacceptable.

[0061] In some embodiments, see Figure 6 , Figure 6 Flowchart showing a filter sedimentation detection method according to some embodiments of the present disclosure. Figure 5 The controller in the example environment of the filter sediment discharge detection method shown is executed. Here, the example environment of the filter sediment discharge detection method also includes a main pipeline, a main line, a filter, a recovery line, a first control valve, an injector, a closed-circuit sampler, an oil storage device, and a gas chromatography device (of course, it can also include a second control valve and a third control valve). The controller can establish a communication connection with the filter, the first control valve, the closed-circuit sampler, the oil storage device, and the gas chromatography device. By respectively obtaining the gas chromatography analysis results of the accumulated oil and the gas chromatography analysis results of the precipitated oil, it can be determined whether the oil quality of the accumulated oil and the precipitated oil are the same, thereby avoiding waste of the accumulated oil. In addition, the oil delivery pipeline composed of the filter, the first control valve, the injector, the closed-circuit sampler, and the oil storage device can be used to effectively ensure the delivery efficiency of the accumulated oil and the precipitated oil.

[0062] like Figure 6As shown, at block 602, method 600 may determine whether the settled oil output by the filter has passed inspection when there is accumulated oil stored in the oil storage device. Here, accumulated oil can be understood as the oil stored in the settling tank before the filter processes filtered oil requiring sedimentation testing. To ensure the accuracy of sedimentation testing of the filtered oil, the controller may control the filter to output this accumulated oil through the settling tank to the oil storage device, so that the settled oil discharged from the filtered oil can be stored in the settling tank while the filter processes the filtered oil requiring sedimentation testing. It is understood that the method for the controller to determine whether the settled oil output by the filter has passed inspection can be found in the above-described embodiments and will not be elaborated upon here.

[0063] At block 604, in response to determining that the deposited oil product has passed the test, method 600 may determine whether the deposited oil product is consistent with the deposited oil product based on the similarity between the gas chromatography analysis results of the deposited oil product and the gas chromatography analysis results of the deposited oil product. Here, after determining that the deposited oil product has passed the test, the controller may issue a command to the gas chromatography device to cause the gas chromatography device to analyze the deposited oil product in the oil storage device to obtain the contents of different components in the deposited oil product, i.e., the gas chromatography analysis results of the deposited oil product. Furthermore, the controller may control the filter to output the deposited oil product in the sedimentation tank to the closed-circuit sampler. After obtaining the gas chromatography analysis results of the deposited oil product, the controller may again issue a command to the gas chromatography device to cause the gas chromatography device to analyze the deposited oil product in the closed-circuit sampler to obtain the contents of different components in the deposited oil product, i.e., the gas chromatography analysis results of the deposited oil product. It is understandable that the use of a gas chromatography device to analyze the stored oil in the oil storage device and the method of analyzing the precipitated oil in the closed-circuit sampler are conventional technical means in this field and will not be described in detail here.

[0064] Then, the controller can also standardize the gas chromatography analysis results of the stored oil products and the gas chromatography analysis results of the deposited oil products respectively to obtain the corresponding gas chromatography analysis result vectors of the stored oil products and the gas chromatography analysis result vectors of the deposited oil products, and can, but is not limited to, use the Euclidean distance calculation method to calculate the gas chromatography analysis result vectors of the stored oil products and the gas chromatography analysis result vectors of the deposited oil products, and the calculation result obtained is the similarity between the gas chromatography analysis results of the stored oil products and the gas chromatography analysis results of the deposited oil products. If the similarity does not exceed the preset similarity threshold, it indicates that there is a large difference in the oil quality of the stored oil and the precipitated oil. At this time, the controller can determine that the stored oil is inconsistent with the precipitated oil, and then, in order to avoid the precipitated oil from mixing with the stored oil, an instruction can be issued to the oil storage device to enable the oil storage device to discharge the stored oil, and after the oil storage device discharges the stored oil (of course, it can also include the cleaning of the oil storage device, but will not be elaborated here), an instruction is issued to the closed-circuit sampler to control the closed-circuit sampler to output qualified precipitated oil to the oil storage device, and then when the first control valve is opened, the qualified precipitated oil in the oil storage device is sucked into the ejector under the action of the negative pressure provided by the filtered oil, thereby realizing efficient transportation of qualified precipitated oil.

[0065] At block 606, method 600 may, in response to determining that the accumulated oil product is consistent with the deposited oil product, output the deposited oil product to the oil storage device and control the first control valve to open. Here, if the similarity exceeds a preset similarity threshold, indicating that the accumulated oil product and the deposited oil product have similar quality, the controller may determine that the accumulated oil product is consistent with the deposited oil product. To avoid wasting the accumulated oil product, the controller may issue a command to the closed-circuit sampler to control the closed-circuit sampler to output the qualified deposited oil product to the oil storage device. At this point, both the deposited oil product and the accumulated oil product are present in the oil storage device. Furthermore, the controller may issue a command to the first control valve so that when the first control valve is opened, the negative pressure provided by the filtered oil product draws both the qualified deposited oil product and the accumulated oil product from the oil storage device into the ejector, thereby achieving efficient delivery of the qualified deposited oil product and the accumulated oil product.

[0066] In some embodiments, the method further comprises: Determine the flow rate control range based on the pipeline parameters on the pipeline between the filter and the closed-circuit sampler and the oil parameters of the precipitated oil; Determining whether a flow rate detection value of the precipitated oil product is abnormal based on the flow rate control interval; and In response to determining that the flow rate detection value of the precipitated oil product is abnormal, the flow rate at which the filter outputs the precipitated oil product to the closed-circuit sampler is adjusted.

[0067] Since the existing technology does not design a control valve for controlling the flow rate in the corresponding pipeline when outputting the precipitated oil to the closed-circuit sampler, the precipitated oil is likely to cause turbulence due to the excessive flow rate output to the closed-circuit sampler. In addition, the pipeline between the precipitated oil and the closed-circuit sampler affects the transportation of the precipitated oil, which can easily lead to inaccurate adjusted flow rate of the precipitated oil, and thus cannot ensure that the precipitated oil will no longer cause turbulence after the flow rate is adjusted.

[0068] Here, when the controller controls the sedimentation tank of the filter to output the precipitated oil to the closed-circuit sampler, it can also determine the flow rate control range based on the pipeline parameters on the pipeline between the filter and the closed-circuit sampler, the oil parameters of the precipitated oil, and the preset flow parameter range. Among them, the pipeline parameters on the pipeline between the filter and the closed-circuit sampler can be understood as the pipeline diameter on the pipeline between the filter and the closed-circuit sampler, the oil parameters of the precipitated oil may include the fluid viscosity and fluid density of the corresponding filtered oil, and the preset flow parameter range can be understood as the flow parameter range required for the fluid to avoid turbulent flow or laminar flow (which can be but is not limited to 2500-4000). When determining the flow rate control range, for example, the pipeline parameter D on the pipeline between the filter and the closed-circuit sampler, the oil parameters P and E of the precipitated oil, and the preset flow parameter range U can be substituted into the following formula: V = (E*U) / (D*P) In the above formula, V may correspond to the flow rate control interval, where when U is the maximum value in the preset flow parameter interval, V is the maximum value in the flow rate control interval, and when U is the minimum value in the preset flow parameter interval, V is the minimum value in the flow rate control interval; E may correspond to the fluid viscosity in the oil parameters of the precipitated oil, U may correspond to any value in the preset flow parameter interval, D may correspond to the pipeline parameter on the pipeline between the filter and the closed-circuit sampler, and P may correspond to the fluid density in the oil parameters of the precipitated oil.

[0069] Next, after obtaining the flow rate control range, the controller can issue a command to a flow rate detection device located on the pipeline between the settling tank and the closed-circuit sampler, thereby obtaining a real-time flow rate measurement value of the precipitated oil product through the flow rate detection device. It is understood that when the flow rate measurement value is within the flow rate control range, it indicates that the precipitated oil product will not cause turbulence in the closed-circuit sampler, that is, the flow rate measurement value of the precipitated oil product is normal. In this case, the controller can maintain the flow rate of the precipitated oil product output from the settling tank to the closed-circuit sampler unchanged. When the flow rate measurement value is not within the flow rate control range, it indicates that the precipitated oil product will cause turbulence in the closed-circuit sampler. In this case, the controller can adjust the flow rate of the precipitated oil product output from the filter to the closed-circuit sampler based on a preset flow rate-valve opening relationship, so that the flow rate measurement value collected by the flow rate detection device again falls within the flow rate control range, thereby ensuring that the precipitated oil product no longer experiences turbulence after the flow rate adjustment. For example, taking the case where the flow rate detection value is greater than the maximum value within the flow rate control interval, the controller can calculate the difference between the flow rate detection value and the maximum value within the flow rate control interval, and determine the valve adjustment opening corresponding to the difference result based on the preset flow rate-valve opening correspondence, and then issue an instruction to the control valve on the pipeline between the sedimentation tank and the closed-circuit sampler to make the control valve reduce the current valve opening according to the valve adjustment opening.
