Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil and gas production, specifically to a quick-opening condensate oil filtration device. Background Technology
[0002] In the production, gathering, transportation, and commercial transshipment stages of the oil and gas industry, liquid products produced from wellheads or extracted from storage tanks, such as crude oil and condensate, often contain various solid particles, suspended matter, and mechanical impurities due to formation carryover, pipeline corrosion, or chemical reactions. To ensure the purity of the oil, meet the requirements of downstream processing technologies, and protect critical equipment such as pumps, valves, and metering instruments from wear or blockage, filtration must be performed at key points in the pipeline. Y-type filters are commonly used on tank trucks to filter suspended matter in the oil. Y-type filters are internal pressure filters; their working principle is that as condensate passes through the filter screen, suspended matter and impurities are collected in the filter pocket. Because the filter pocket area is small, suspended matter quickly covers the filter screen during oil intake, hindering filtration and causing the oil intake rate to gradually decrease. At this point, the filter plug needs to be removed, the filter screen cleaned, and then reinstalled. Removing the plug can easily spill oil onto the ground, and since the filter plug is 65mm in diameter, removing it requires a large, specialized tool. Cleaning the filter screen is time-consuming each time, negatively impacting oil loading. Figure 1 As shown.
[0003] When processing fluids with high impurity content, the effective filtration area of traditional filters is relatively limited, causing the filter screen surface to be covered by impurities in a short time, resulting in a rapid increase in pressure differential and a sharp decrease in flow rate, i.e., filter blockage.
[0004] Once a blockage occurs, the operation must be interrupted to maintain the filter. This requires disassembling the filter housing to remove the internal filter element for cleaning or replacement. This process is not only cumbersome and time-consuming, but also often results in leakage or spillage of residual oil from the housing during disassembly and assembly. This can lead to economic losses of materials and may also cause environmental pollution and safety hazards at the work site. Utility Model Content
[0005] In order to solve the above-mentioned technical problems, this utility model provides a quick-opening condensate oil filtration device, which can not only ensure the filtration effect, but also achieve quick, convenient and clean cleaning and maintenance.
[0006] This utility model is achieved through the following technical solution:
[0007] A quick-opening condensate oil filtration device, comprising:
[0008] The separator is equipped with an oil inlet and an installation opening;
[0009] A filter element assembly having an oil outlet is installed at the installation opening. The interior of the filter element assembly is configured as a post-filter chamber communicating with the oil outlet. When the filter element assembly is installed in the separation box, the filter element assembly defines the space between the inner side of the separation box and the outer side of the filter element assembly as a pre-filter chamber communicating with the oil inlet.
[0010] A drain valve is located at the bottom of the separation tank and communicates with the pre-filter chamber.
[0011] Furthermore, it also includes a quick-connect fitting for removably sealing the filter assembly at the mounting opening of the separator.

[0015] A filter screen is installed at the inner end of the filter element body.
[0016] Optionally, the outer end of the filter element body is connected to a quick-connect oil outlet for connection with an oil tanker.
[0017] Optionally, the quick-connect oil outlet includes a connector body and at least one fastening handle pivotally connected to the connector body.

[0027] Optionally, the separation box is made of aluminum alloy, and the drain valve is a ball valve.
[0028] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0029] This invention sets the filtration mode to filter from the outside to the inside of the filter assembly, so that the intercepted suspended solids and impurities can be collected in the relatively spacious pre-filter chamber, rather than directly and densely adhering to the filter screen surface. Therefore, this structure greatly slows down the clogging speed of the filter screen, thereby extending the effective cycle of a single continuous operation of the device.
[0030] By installing a drain valve at the bottom of the pre-filter chamber that contains impurities, operators can easily drain the impurities and small amounts of residual liquid that have settled at the bottom of the separation tank without emptying the main equipment or disassembling the core components. This simplifies the daily maintenance process and significantly reduces material waste caused by frequent disassembly and assembly.
[0031] By using quick-connect fittings to install the entire filter assembly, the entire assembly can be quickly removed from the separator without the need for special tools when deep cleaning is required. This greatly reduces downtime for maintenance, lowers the workload of operators, and significantly improves overall work efficiency. Attached Figure Description

[0046] Where there is no conflict, the embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0047] Example 1
[0048] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the quick-opening condensate oil filtration device disclosed in this embodiment achieves filtration and impurity sedimentation separation by constructing a specific internal fluid path, guiding the condensate oil containing impurities into an external containment chamber, and then allowing it to pass through a filter medium into an internal clean chamber, ultimately achieving the separation of oil and impurities. Specifically, it includes: a separation box 8, a filter element assembly 2, and a drain valve 4.
[0049] The function of the separator 8 is to contain the oil to be treated and the core filter assembly. The separator 8 is provided with an oil inlet and an installation opening. The oil inlet is used to connect to the upstream pipeline to allow condensate oil to enter the interior of the unit. The installation opening is usually located at the end of the unit and is used to install and fix the core filter assembly 2.
[0050] The filter element assembly 2 is installed as an independent filtration unit at the installation opening of the separator 8. The filter element assembly 2 has an oil outlet, and the interior of the filter element assembly 2 is set as a post-filtration chamber that communicates with the oil outlet. When the filter element assembly 2 is installed in the separator 8, the filter element assembly 2 defines the space between the inside of the separator 8 and the outside of the filter element assembly 2 as a pre-filtration chamber that communicates with the oil inlet. Condensate oil containing suspended solids first enters this area.
[0051] The filtration direction of the oil must be "from the outside to the inside" - that is, the oil passes through the filter medium of the filter element assembly 2 from the pre-filter chamber, enters the post-filter chamber, and then flows out from the oil outlet.
[0052] The drain valve 4 is located at the bottom of the separator 8 and is connected to the pre-filter chamber. Due to gravity, the denser solid impurities separated from the oil will naturally settle to the bottom of the separator 8, which is the lowest point of the pre-filter chamber. Therefore, the drain valve 4 can be used to periodically or as needed discharge these deposited impurities without affecting the main filtration process.
[0053] The working principle and operation steps of this embodiment can be summarized as follows: The condensate oil to be treated enters the pre-filter chamber surrounding the filter element assembly 2 through the oil inlet, and permeates the filter element assembly 2 under pressure. During this process, suspended solids and other impurities are intercepted and retained in the relatively large pre-filter chamber, with some impurities settling to the bottom of the chamber under gravity. The purified condensate oil then enters the post-filter chamber inside the filter element assembly 2 and finally flows out from the oil outlet. When cleaning is required, the deposited impurities can be directly discharged through the drain valve 4 at the bottom.
[0054] Example 2
[0055] The design concept of this embodiment is to use a tool-free, hand-operable mechanical structure to replace traditional connection methods such as flange bolts that require a lot of time to tighten or disassemble, thereby reducing the maintenance time of filter assembly 2 from tens of minutes to a few seconds.
[0056] To achieve this objective, this embodiment adds a quick-connect connector 10 at the installation opening of the separation box 8. Preferably, this is a molded DN120C type aluminum alloy quick-connect connector. Figure 5 As shown, one end of the connector (e.g., by thread) is fixedly connected to the mounting opening of the separator 8, while the other end is used to mate with a corresponding part (e.g., a DP-type inner plug) on the filter element assembly 2.
[0057] The quick-connect connector 10 includes a connector body and at least one fastening handle 1 pivotally connected to the connector body, the fastening handle 1 having an eccentric clamping structure.
[0058] The connector body is the main annular structure of the connector, with an eccentric clamping structure consisting of a cam or eccentric wheel mechanism. The fastening handle 1 is made of thickened zinc alloy. When the fastening handle 1 is in the open position, its eccentric structure does not generate pressure, allowing the filter element assembly 2 to be easily inserted into or removed from the connector body. When the operator manually moves the handle to the closed position, the handle rotates around its axis, and its eccentric contour gradually presses against the corresponding structure of the filter element assembly 2. As the handle is fully engaged, the pressure generated by the eccentric structure reaches its maximum, pressing the sealing ring against the installation opening of the separation box 8, thus forming a strong and completely leak-proof seal. Reversing the operation, i.e., pulling the handle open, instantly releases this pressure, allowing the filter element assembly 2 to be easily removed.
[0059] Example 3
[0060] like Figure 4 As shown, the filter assembly 2 includes: a hollow filter body and a filter screen 3.
[0061] The middle part of the filter element body passes through the connector body of the quick-connect fitting. The inner end of the hollow filter element body is located inside the separation box 8, and the inner end is the working end for performing filtration operations. The outer end of the filter element body is located outside the separation box 8, and the outer end constitutes the outlet of clean oil products. It is also the main gripping part for operators when installing or disassembling the filter element.
[0062] Filter screen 3 is used to intercept suspended solids and impurities. It is installed at the inner end of the filter element body and is in full contact with the condensate oil to be treated.
[0063] To achieve ideal filtration effect and structural strength, filter screen 3 has a cylindrical structure, providing a large effective filtration area; the exterior of filter screen 3 is a stainless steel honeycomb frame, providing rigidity and structural support to ensure that filter screen 3 will not deform or be damaged under fluid pressure.
[0064] The interior of filter screen 3 is made of stainless steel mesh. The mesh count can be customized according to technical requirements. The higher the mesh count, the smaller the mesh openings and the higher the filtration accuracy.
[0065] In addition, for ease of maintenance, one end of the filter screen 3 is threaded. The thread allows the filter screen 3 to be easily screwed onto the inner end of the filter element body, making the filter screen 3 a detachable and replaceable independent component.
[0066] Example 4
[0067] This embodiment provides how the condensate oil to be processed enters the unit from the source (e.g., a well site) and how the clean condensate oil is transported from the unit to downstream tank trucks.
[0068] A quick-connect fitting 11 for connecting to an oil tanker is connected to the outer end of the filter element body. According to the preferred embodiment, the quick-connect fitting 11 is a DN80C type molded part made of aluminum alloy. It is a component of the filter element assembly 2 and is connected to the E type quick-connect fitting of the oil tanker to fix and seal.
[0069] Similar to the connection mechanism used to fix the filter assembly 2 in Embodiment 2, the oil outlet quick connector 11 also adopts a manual quick-opening structure. The oil outlet quick connector 11 includes a connector body and at least one fastening handle 1 pivotally connected to the connector body. The fastening handle 1 has an eccentric pressing structure for locking and fixing the oil outlet quick connector 11 to the oil inlet connector of the tanker truck.
[0070] When connecting this device to an oil tanker, the operator simply aligns and inserts the quick-connect oil outlet 11 with the oil inlet connector of the oil tanker, and then pulls the fastening handle 1. The eccentric clamping structure (cam mechanism) on the handle will then activate, generating a strong locking force that firmly secures the two connectors together and simultaneously compresses the sealing ring between them, thus achieving both fixing and sealing functions, ensuring a stable connection and no leakage during oil transportation.
[0071] Furthermore, considering the convenience and cleanliness of the device during transportation and storage, this embodiment also provides a supporting solution: when the filter device is not in operation, matching protective plugs (such as DP and DC type plugs) can be used to seal the oil inlet and outlet of the device respectively. This effectively prevents dust, moisture, and other contaminants from entering the device and also avoids accidental leakage of residual oil inside the device.
[0072] like Figure 7 As shown, a quick-connect oil inlet connector 6 for connecting to the well station is connected to the oil inlet of the separator 8. According to the preferred embodiment, the connector can be a DN80E type molded part made of aluminum alloy.
[0073] One end of the quick inlet connector 6 is fixed to the housing of the separator box 8 by means of threads, which can realize quick connection and disassembly; the other end forms a standard quick connector interface, which is specifically used for quick and tool-free docking with the connector at the end of the well station's oil pipeline.
[0074] Example 5
[0075] At the top of the separation chamber 8, a vacuum valve 9 is installed, which communicates with its interior. This valve is typically made of lightweight, corrosion-resistant materials such as aluminum alloy.
[0076] When the separator 8 is completely sealed, opening the drain valve 4 at the bottom to discharge liquid will create a negative pressure inside the separator, i.e., a "vacuum" state, which will hinder or even prevent the liquid from draining smoothly. At this time, the operator only needs to gently press the button on the vacuum valve 9, and the valve will open, allowing outside air to enter the separator 8. The entry of air instantly eliminates the vacuum, balancing the internal and external pressures, thus ensuring that suspended solids and condensate oil at the bottom of the separator can be quickly and thoroughly discharged under gravity.
[0077] On the side wall of the separation chamber 8, especially in a position that facilitates observation of the pre-filter chamber, a flange sight glass 5 is installed. The flange sight glass 5 includes a flange, a transparent lens, and a seal.
[0078] Two flanges (usually made of aluminum alloy) are used for a fixed and sealed connection with the separation box 8. A transparent lens (preferably high-strength tempered glass) is sandwiched between the two flanges. A sealing element is set between the transparent lens and the flange, and its specifications can be designed according to the box size, for example, a diameter of 65mm.
[0079] During the oil filtration process, operators can directly observe the filtration status of the oil inside the unit, especially the degree of accumulation of suspended solids in the pre-filter chamber. When operators find a large amount of impurities deposited at the bottom of the separator 8 through the sight glass, they can open the drain valve 4 for cleaning, achieving "on-demand maintenance" and avoiding unnecessary shutdowns for inspection.
[0080] A handle 7 is also installed on the outer wall (usually the top) of the separation box 8. The handle 7 is preferably made of stainless steel and is firmly fixed to the box body by bolts or other means, making it convenient for workers to carry by hand.
[0081] Example 6
[0082] The drain valve 4 located at the bottom of the separator 8 is preferably a ball valve. To resist oil corrosion and ensure service life, the ball valve is preferably made of stainless steel, and its specifications can be selected according to the discharge capacity requirements (e.g., DN20).
[0083] During the filtration process, the valve can be opened intermittently to discharge settled suspended solids; after the operation is completed (e.g., after cleaning the filter screen or completing oil filling), it can be opened completely to empty all residual oil in the separator 8. Under certain fixed operating conditions, a return oil pipe can also be connected to the drain valve 4 to achieve near real-time discharge of high-concentration suspended solids.
[0084] The separator 8 is preferably made of aluminum alloy (e.g., 6061 aluminum alloy). As a machined component, the separator 8 typically consists of a section of aluminum alloy round tube of a specific specification (e.g., outer diameter 135 mm, wall thickness 5 mm) as the cylinder body. End caps are welded to both ends to form a sealed pressure vessel. Subsequently, a hole is machined and threads are created at the center of the end caps at both ends. One end is used to connect to the quick-connect fitting 6 for the oil inlet, and the other end is used to connect to the quick-connect fitting 10 for fixing the filter element assembly 2, thus separating oil and suspended solids.
[0085] Example 7
[0086] This embodiment provides a specific operating method.
[0087] Installation and Connection: Before commencing operations, first connect the pipelines. Connect the quick-connect oil inlet 6 to the well site's oil supply line, and connect the quick-connect oil outlet 11 to the oil tanker's inlet. Simultaneously, connect the outlet of the bottom drain valve 4 to a field-provided oil storage tank.
[0088] Filtration Process: After connection, open the valves at both ends of the pipeline. Condensate oil containing suspended solids enters the pre-filter chamber inside the separator 8 through the inlet. Under pressure, the oil prepares to penetrate the filter screen 3. At this point, suspended solids and impurities, due to their larger size, are intercepted outside the filter screen 3. Clean condensate oil then permeates through the fine mesh, enters the post-filter chamber inside the filter screen 3, and finally flows from the outlet to the tanker truck.
[0089] Process monitoring: Throughout the filtration process, operators can observe the internal conditions of the device in real time through the flange sight glass 5. Due to the density characteristics of suspended solids (usually greater than condensate oil but less than the small amount of gas field water that may be mixed in), some of the lighter suspended solids will adhere to the outside of the filter screen 3, while some of the heavier impurities will settle to the bottom of the separation tank 8 along with the gas field water.
[0090] Online drainage: When it is observed through the sight glass that there are a lot of impurities deposited at the bottom of the chamber, the operator can directly open the drain valve 4 to discharge this part of the sediment without interrupting the main filtration operation.
[0091] Online backflushing: When it is found that the suspended matter attached to the outside of filter screen 3 begins to increase, but has not yet seriously affected the flow rate, close the oil inlet valve of the well station to cut off the oil supply. Then, open the drain valve 4 at the bottom. Quickly open and close the oil inlet valve at the tanker end, using the pressure in the pipeline to make a small stream of filtered clean oil flow back from the tanker end, instantly impacting the inner wall of filter screen 3. This will wash off any loosely attached suspended matter on the outside of the filter screen, causing it to fall to the bottom of the separator 8 and flow out from the opened drain valve 4.
[0092] Offline deep cleaning: When a large amount of suspended matter adheres to the filter screen 3 and seriously affects the oil intake speed, a thorough cleaning is required; close the valves at both ends of the well station and the oil tanker, then open the drain valve 4 and press the top vacuum valve 9 to allow air to enter and break the vacuum, completely emptying the oil in the device; remove the entire filter device from the pipeline, open the quick connection connector 10, pull out the entire filter element assembly 2, thoroughly clean the outside of the filter screen 3, and after cleaning, reinstall the filter element assembly 2 into the separator box 8.
[0093] Final purging: After the entire vehicle is filled with oil, close both valves, reopen the drain valve 4 and press the vacuum valve 9 to ensure that all remaining oil in the housing is completely drained from the drain valve 4. Then, disconnect the quick connectors at the inlet and outlet ends in sequence to complete this oil filtration operation.
