Description

Technical Field

[0001] The utility model relates to the technical field of oil, gas and water separation detection, in particular to a filtering device for crude oil water sample detection. Background Art

[0002] In the petroleum energy sector, after the three-phase separation of oil, gas and water, water and gas samples need to be tested, and the corrosion analysis of oil and gas pipelines needs to be carried out based on the test data. The testing of water samples requires filtering out the sand and gravel in the water samples. Although existing filtration equipment can filter water samples to a certain extent, it generally has problems such as low filtration efficiency, easy clogging of the filter screen, and inconvenient maintenance. Especially when processing water samples containing a large amount of sand and gravel, the filter screen is easily clogged due to the attachment of sand and gravel, resulting in a decrease in filtration efficiency and even the need for frequent filter replacement, which increases maintenance costs and operational difficulty.

[0003] Therefore, it is necessary to provide a new filtering device for crude oil water sample detection to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a filtering device for detecting crude oil water samples.

[0005] The utility model provides a filtering device for crude oil water sample detection, comprising a liquid inlet cylinder, a sedimentation cylinder connected to each other fixedly mounted at the bottom of the liquid inlet cylinder, and a partition plate fixedly mounted in the middle of the liquid inlet cylinder, the sedimentation cylinder being divided into a liquid falling channel and a liquid rising channel arranged side by side by the partition plate;

[0006] A detachable sediment component is installed at the bottom of the sedimentation cylinder, and the sediment component includes a threaded cover. A rotating disk with a rotatable connection is installed on the inner bottom wall of the threaded cover, and a slag receiving barrel for plugging the sedimentation cylinder is fixedly installed on the rotating disk, and a stainless steel filter is inserted in the slag receiving barrel.

[0007] Preferably, a central connecting plate is fixedly installed in the middle of the upper barrel mouth of the slag receiving barrel, and the slag receiving barrel is divided into a falling liquid chamber and a rising liquid chamber arranged side by side by the central connecting plate. An insertion groove is opened on the barrel body of the slag receiving barrel corresponding to the rising liquid chamber, and the stainless steel filter is inserted into the insertion groove.

[0008] Preferably, the bottom fixing sleeve of the sedimentation cylinder is provided with a threaded ring, and the threaded cover is fixedly connected to the threaded ring through threads.

[0009] Preferably, a convection port is formed between the central connecting plate and the inner bottom wall of the slag receiving barrel.

[0010] Preferably, a vertical plate is fixedly installed in the liquid inlet cylinder, and a docking port is provided between the vertical plate and the inner top wall of the liquid inlet cylinder, and the cavity between the vertical plate and the liquid inlet cylinder constitutes a liquid storage cavity.

[0011] Preferably, a liquid inlet interface and a liquid discharge interface are fixedly installed on the liquid inlet cylinder, the liquid inlet interface is communicated with the liquid falling channel, and the liquid discharge interface is communicated with the liquid storage cavity.

[0012] Compared with related technologies, the filtering device for crude oil water sample detection provided by the utility model has the following beneficial effects:

[0013] Since the sand and gravel impurities in the water are relatively heavy, the utility model allows most of the sand and gravel impurities in the water to be automatically settled into the threaded cover in the flow path of the falling liquid flow channel → the falling liquid chamber → the convection port → the rising liquid chamber, and some particles are also filtered out under the action of the stainless steel filter. Since the particulate impurities are basically filtered out by sedimentation, there is less sand and gravel attached to the bottom of the stainless steel filter, thereby greatly extending the cycle of cleaning and replacing the stainless steel filter.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] See also Figures 1 to 7 The embodiment of the present invention provides a filtering device for detecting crude oil water samples, which includes a liquid inlet cylinder 1, a sedimentation cylinder 2, a sediment component 4 and a stainless steel filter 5.

[0025] In the embodiments of the present invention, please refer to Figures 1 to 7 , a sedimentation cylinder 2 that is interconnected is fixedly installed at the bottom of the liquid inlet cylinder 1, and a dividing plate 3 is fixedly installed in the middle of the liquid inlet cylinder 1, which divides the sedimentation cylinder 2 into a falling liquid flow channel 1a and a rising liquid flow channel 1b arranged side by side through the dividing plate 3, and a vertical plate 13 is fixedly installed in the liquid inlet cylinder 1, and a docking port 1c is left between the vertical plate 13 and the inner top wall of the liquid inlet cylinder 1, and the cavity between the vertical plate 13 and the liquid inlet cylinder 1 constitutes a liquid storage chamber 1d, and a liquid inlet interface 11 and a liquid discharge interface 12 are fixedly installed on the liquid inlet cylinder 1, the liquid inlet interface 11 and the falling liquid flow channel 1a are communicated with each other, and the liquid discharge interface 12 and the liquid storage chamber 1d are communicated with each other, and a threaded ring 21 is fixedly provided on the bottom of the sedimentation cylinder 2;

[0026] A detachable sediment component 4 is installed at the bottom of the sedimentation cylinder 2, and the sediment component 4 includes a threaded cover 41, which is fixedly connected to the threaded ring 21 by threads, and a rotating disk 42 is installed on the inner bottom wall of the threaded cover 41, and a slag receiving cylinder 43 for inserting the sedimentation cylinder 2 is fixedly installed on the rotating disk 42, and a stainless steel filter screen 5 is inserted in the slag receiving cylinder 43. Specifically, a central connecting plate 44 is fixedly installed in the middle of the upper tube mouth of the slag receiving cylinder 43, and the slag receiving cylinder 43 is divided into a falling liquid chamber 43a and a rising liquid chamber 43b arranged side by side by the central connecting plate 44. An insertion groove 43c is opened on the cylinder body of the slag receiving cylinder 43 corresponding to the rising liquid chamber 43b, and the stainless steel filter screen 5 is inserted into the insertion groove 43c, and a convection port 44a is formed between the central connecting plate 44 and the inner bottom wall of the slag receiving cylinder 43.

[0027] In this application, the liquid inlet interface 11 is connected to the liquid inlet pipe (the liquid inlet pipe is used to transport the water separated from the crude oil), and the liquid discharge interface 12 is connected to the liquid storage tank, and then the stainless steel filter screen 5 is inserted into the insertion groove 43c, so that the stainless steel filter screen 5 can filter the liquid discharged from the rising liquid chamber 43b, and then the slag receiving tube 43 is inserted into the bottom of the sedimentation tube 2, keeping the falling liquid chamber 43a corresponding to the falling liquid flow channel 1a, and the rising liquid chamber 43b corresponding to the rising liquid flow channel 1b, and then the threaded cover 41 is tightened and fixed on the threaded ring 21 to complete the installation of the sediment component 4 on the sedimentation tube 2, and at this time the center plate 44 is against the dividing plate 3.

[0028] It should be noted that when the liquid enters the liquid inlet cylinder 1 through the liquid inlet interface 11, its specific flow path is:

[0029] Liquid inlet port 11 → liquid falling channel 1a → liquid falling chamber 43a → convection port 44a → liquid rising chamber 43b → liquid rising channel 1b → docking port 1c → liquid storage chamber 1d → liquid discharge port 12;

[0030] Since the sand and gravel impurities in the water are relatively heavy, most of the sand and gravel impurities in the water are automatically settled into the threaded cover 41 in the flow path of the falling liquid channel 1a → falling liquid chamber 43a → convection port 44a → rising liquid chamber 43b, and some particles are also filtered under the action of the stainless steel filter 5. Because the particulate impurities are basically filtered by sedimentation, there is less sand and gravel attached to the bottom of the stainless steel filter 5, which greatly extends the cycle of cleaning and replacing the stainless steel filter 5.

[0031] Among them, when processing the sand and gravel particles accumulated in the stainless steel filter screen 5 and the threaded cover 41, the stainless steel filter screen 5 is slid out after unscrewing the threaded cover 41, so that the stainless steel filter screen 5 can be cleaned or replaced. At the same time, the bottom of the threaded cover 41 can be rinsed with water to remove the sand and gravel accumulated at the bottom of the threaded cover 41.

[0032] It is worth noting that: during filtration, a pressure reducing valve may be provided on the liquid inlet pipe to reduce the flow rate of the water entering the liquid inlet cylinder 1 , making it easier for the sand and gravel in the water to settle.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
