Description

Technical Field

[0001] This utility model relates to the field of liquid receiving devices for viewing the medium inside a tank, and particularly to a splash-proof, self-cleaning viewing window device. Background Technology

[0002] In the chemical industry, there are many liquid separators, most of which separate incompatible components of different densities based on the principle of gravity sedimentation. For example, in oil-water separators used in crude oil production processes, the height of the oil-water interface significantly impacts the separation efficiency, requiring close monitoring of its value. Separators are typically equipped with float-type oil-water interface meters to display the height of a specified density layer within the tank. However, factors such as throughput, temperature, reagents, and changes in formation oil quality are constantly changing, causing the density of the oil-water interface to alter. Therefore, a float with a fixed density cannot accurately display the constantly changing oil-water interface. This necessitates periodic external observation to verify the true oil-water interface. However, traditional external viewing windows pose a risk of high-pressure liquid impacting the bottom of the window, causing splashing, which not only pollutes the environment but also poses safety risks to operators. Furthermore, traditional viewing windows easily accumulate oil and require regular cleaning and maintenance. Therefore, a splash-proof, self-cleaning viewing window is urgently needed on-site. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, this utility model provides a splash-proof self-cleaning viewing window device.

[0004] This utility model is achieved by adopting the following technical solution.

[0005] A splash-proof self-cleaning viewing window device includes a viewing window housing and a viewing window cover. The rear bottom of the viewing window housing is an arc-shaped splash-proof plate, and the front bottom of the viewing window housing forms a buffer vortex. An inclined self-flowing slope is formed along the length of the viewing window housing at the junction of the splash-proof plate and the buffer vortex.

[0006] By adopting the above technical solution, the bottom of the traditional viewing window box is first changed from a flat surface to an arc surface. When the oilfield separator needs to be exposed to view the oil-water interface, the viewing window cover is opened first, and then the valves of each height pipeline are slowly opened. The high-pressure liquid in the pipeline flows out from the pipeline outlet, and passes through the arc-shaped anti-splash plate and the buffer vortex for diversion and friction to reduce kinetic energy. After being splashed, the liquid collects at the junction of the anti-splash plate and the buffer vortex. Then, because the junction of the anti-splash plate and the buffer vortex is designed with one side raised by 2°-3°, a self-flowing slope is formed. The liquid that has lost kinetic energy will automatically carry the crude oil downstream of the self-flowing slope under its own gravity. Finally, the oil-water mixture flows out from the drainage pipeline downstream of the self-flowing slope, achieving self-cleaning inside the viewing window, reducing labor intensity and saving manpower.

[0007] Furthermore, a vertically arranged window cover guide plate is connected to the window cover, and the length of the window cover guide plate is equal to the length of the window box body.

[0008] By adopting the above technical solution, a deflector is added to the viewing window cover. When the viewing window cover is closed, the condensate on the cover will be guided into the viewing window box by gravity, preventing oily sewage from flowing out from the gaps in the viewing window cover, thus eliminating the need for frequent cleaning.

[0009] Furthermore, the curvature of the splash guard increases with the direction of liquid flow.

[0010] Furthermore, the initial contact angle θ between the liquid and the splash guard is greater than... Where d is the thickness of the viewing box; d1 is the distance from the center line of the outlet pipeline to the rear edge of the viewing box; h is the vertical distance from the point of contact between the fluid and the viewing box to the top surface of the viewing box; and h1 is the vertical distance from the lower edge of the viewing window to the top surface of the viewing box.

[0011] Furthermore, the end extension line of the buffer spin deviates from the viewing window.

[0012] Furthermore, the angle between the self-flowing slope and the horizontal plane is 2°-3°.

[0013] This application has the following beneficial effects.

[0014] This utility model is a viewing window device for external viewing media interfaces. It can effectively solve the problems of oil and water splashing, accumulation of materials requiring regular cleaning, and environmental pollution from the gaps in the cover of traditional viewing windows. It has anti-splash and self-cleaning functions, realizing the viewing window without hygiene cleaning and maintenance, thus improving quality and efficiency. Moreover, the viewing window itself is inherently safe and environmentally friendly. Attached Figure Description

[0017] The present patent application will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-2 As shown, a splash-proof self-cleaning viewing window device includes a viewing window housing 7 and a viewing window cover 5.

[0019] The viewing window housing 7 includes a front bottom and a rear bottom connected to each other. A top surface (top cover) is connected to the upper end of the rear bottom. A viewing window is formed between the upper end of the front bottom and the edge of the top surface. A viewing window cover 5 is provided on the viewing window. The viewing window cover 5 is inclined and connected to the upper end of the front bottom.

[0020] The rear bottom of the viewing box 7 is a splash guard 1 with an arc-shaped design. The curvature increases with the direction of liquid flow. As long as the initial contact angle between the high-speed liquid and the splash guard 1 is controlled within a certain range, the functions of initial splash prevention, diversion and reduction of kinetic energy of the liquid can be achieved.

[0021] The front bottom of the viewing window housing 7 is a buffer swivel 2, which is connected to the anti-splash plate 1. The extension line of the end of the buffer swivel 2 is offset from the viewing window. Under the action of gravity, it plays a secondary anti-splash function for liquid, and also has the function of further reducing the kinetic energy of the liquid.

[0022] The bottom of the viewing box 7 is a self-flowing slope 3, located at the junction of the anti-splash plate 1 and the buffer swivel 2. The design places the easy-to-clean water layer on its high side and the difficult-to-clean oil layer on its low side. When in use, the water on the high side will automatically carry the oil on the low side downstream, which plays a role in preventing sedimentation and self-cleaning.

[0023] A deflector plate 6 is provided on the viewing window cover 5. The viewing window cover 5 serves to prevent debris from entering the viewing window and to keep it warm. Oily wastewater will condense on the viewing window cover 5 and will flow out through the gaps in the viewing window cover 5, polluting the environment. The deflector plate 6 is designed to fill the gaps in the viewing window and can automatically guide the condensed liquid into the viewing window housing 7 by gravity, thus protecting the environment.

[0024] When the operator checks the medium status at each height in the tank at the observation point, the valve of the pipeline at that height is turned on, and the liquid is sprayed from the pipeline into the viewing window. It first passes through the arc-shaped anti-splash plate 1 to guide and reduce kinetic energy, then passes through the buffer vortex 2 to further reduce kinetic energy and prevent it from flying out of the viewing window, and finally achieves self-cleaning on the gravity slope 3 by the weight of the liquid itself.

[0025] This invention achieves anti-splash and self-cleaning functions under high-pressure fluid impact during operation by optimizing the window shape. For example... Figure 3-4As shown, the bottom of the traditional viewing box 7 is flat. When the high-pressure fluid encounters the flat surface, it splashes, and the direction is uncontrollable. This application analyzes the direction of liquid splashing based on the principle of total internal reflection. After introducing the anti-splash plate 1, under the condition that other parameters are determined, directional splashing can be achieved by optimizing the curvature and contact angle of the anti-splash plate 1. The specific research and development process of this application is as follows.

[0026] The angle requirement at splash guard 1: Assuming the fluid ejected from the pipeline outlet is totally reflected due to the absence of gravity, the thickness of the viewing window housing 7 is d, the distance from the centerline of the outlet pipeline to the rear edge of the viewing window housing 7 is d1, the vertical distance from the contact point A between the fluid and the viewing window housing 7 to the top surface of the viewing window housing 7 is h, the vertical distance from the lower edge B of the viewing window to the top cover of the viewing window housing 7 is h1, the angle between the tangent of the curved surface at point A and the horizontal ground is θ, and the reflection angle is α. Through derivation, we know that α = 2θ. Increasing θ at this point increases α, requiring a decrease in the curvature of the splash guard 1 surface. When the reflected ray of α just passes through point B, further increasing α will cause the reflected ray to be lower than the lower edge of the viewing window, thus preventing fluid splashing. Define θ or α at this point as the minimum limiting angle, such as... Figure 5 As shown, θ > 0 can be obtained when splash protection is achieved. .

[0027] After the high-speed fluid passes through the anti-splash plate 1 and the buffer vortex 2 to reduce its kinetic energy through flow and friction, if it still has significant kinetic energy, a secondary anti-splash is required to prevent the upward-flowing fluid from directly flying out of the viewing window. Therefore, the tangent at the end of the buffer vortex 2 should be lower than the viewing window, and excess material can be removed to reduce the amount of material used in the viewing window. Figure 6 As shown.

[0028] After two diversions and kinetic energy reductions, the fluid's kinetic energy is significantly reduced, converging at the junction of the splash guard 1 and the buffer vortex 2. At this point, the gravity-fed drainage slope 3, inclined at the junction of splash guard 1 and buffer vortex 2, allows for drainage. The drain outlet is located downstream of the gravity-fed slope 3. Simultaneously, based on the pipeline distribution of the observation window station, clean water is placed upstream of the gravity-fed slope 3, while oil, which is more difficult to clean, is placed downstream. The relatively clean and fluid water, under the influence of gravity, automatically propels or carries the oil downstream of the gravity-fed slope 3, achieving self-cleaning within the observation window. Figure 7 As shown.

[0029] Meanwhile, in response to the problem of condensation from the gaps in the window cover 5 causing environmental pollution, this invention adds a window cover guide plate 6 at the junction of the window cover 5 and the gap, which automatically guides the condensed liquid into the window housing 7 by gravity, thus preventing environmental pollution.

[0030] When it is necessary to check the oil-water interface, first open the viewing window cover 5, then slowly open the valves of each height pipeline. The high-pressure liquid in the pipeline flows out from the pipeline outlet, and after passing through the anti-splash plate 1 and the buffer vortex 2 for guidance and friction to reduce kinetic energy, it gathers at the junction of the anti-splash plate 1 and the buffer vortex 2. Then, relying on the inclination angle of the gravity flow slope 3 and its own gravity, it flows downstream to the viewing window outlet and is finally discharged through the drain pipeline 4. Because the high-density layer of the separator is set upstream of the gravity flow slope 3, and its medium is water with good fluidity and relatively cleanliness, it will automatically carry the crude oil released from the low-density layer downstream of the gravity flow slope 3, realizing self-cleaning inside the viewing window. After the operation is completed, close the viewing window cover 5. The condensate will be covered, and the viewing window cover guide plate 6 will guide the condensate into the viewing window housing 7, preventing oily wastewater from flowing out from the gaps in the viewing window cover, thus achieving quality improvement, efficiency enhancement, safety and environmental protection.

[0031] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
