Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically to a self-cleaning optical oil sensor in water for use in automatic water cutters. Background Technology

[0002] Due to the petrochemical process, petroleum products always contain a certain amount of water, even in trace quantities. When petroleum is stored in large tanks, water, being denser than oil, slowly settles at the bottom. Therefore, oil and water are typically separated using a water separator. With the development of water separator technology, automatic water separators have become standard equipment in the field of petroleum storage tank technology. Sensing technologies for identifying the oil-water boundary and detecting the oil-water ratio within the water separator are increasingly advanced. Furthermore, when crude oil is pumped to the surface, it contains many impurities (such as water and sand). In actual operation, these impurities are separated, and the water remaining after impurity separation is called produced water. Produced water contains a lot of oil and cannot be directly discharged or used. The oil must be further separated from the produced water to ensure that the discharged water meets environmental standards, requiring monitoring of its oil content. Currently, the most accurate sensor for measuring oil content in water is the optical oil sensor. However, oil tends to adhere to the window of the optical oil sensor, making the window blurry and reducing accuracy. As a result, the measurement results are not satisfactory. Therefore, most optical oil sensors cannot be truly applied in practice for accurate detection of oil content in water. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the above-mentioned technical problems and provide a self-cleaning optical oil sensor in water for an automatic water cutter, including a pipe (11), a first window (12) and a second window (13) that are disposed through the wall of the pipe, and a mounting hole (14). The first window and the second window are both solid structures in the shape of a stepped shaft. The end face of the first window (12) and the end face of the second window (13) are arranged at intervals and are both disposed in the pipe (11). The utility model also includes a flushing assembly disposed in the mounting hole (14) and aligned with the first window and the second window. The flushing assembly is connected to an external pipeline.

[0004] Furthermore, the flushing assembly includes a nozzle (2), one end of which is provided with a jet injection hole (21), and the other end is provided with a flow channel (22) communicating with the jet injection hole (21). The nozzle (2) passes through the side wall of the pipe (11) and is threadedly connected to the pipe (11).

[0005] Furthermore, a hexagonal head (23) for rotating the nozzle is fixedly provided on the nozzle (2).

[0006] Furthermore, the nozzle (2) is provided with two jet injection holes (21) respectively aligned with the first window and the second window. The jet injection holes (21) are flat-nozzle shaped, and the ejection direction of the jet injection holes (21) forms an angle of 1-4° with the surfaces of the first window (12) and the second window (13).

[0007] Furthermore, the flushing assembly includes a flushing seat (31) disposed on the mounting hole (14). One end of the flushing seat (31) is provided with a flow channel (32) communicating with the pipeline, and the other end is provided with a fork-shaped nozzle (33). The fork-shaped nozzle (33) is provided with two jet injection holes (34), and one end of the jet injection hole (34) is connected to the flow channel (32).

[0008] Furthermore, the distance between the two jet injection holes (34) increases sequentially along the direction from the flushing seat (31) to the mounting hole (14), and the high-pressure steam or high-pressure water or high-pressure air ejected from the two jet injection holes (34) form an angle of 1-4° with the surfaces of the first window (12) and the second window (13), respectively.

[0009] Furthermore, the flushing seat (31) is provided with an annular sealing groove (35) on the side near the pipe, and a sealing ring is provided in the annular sealing groove (35).

[0010] This invention provides a self-cleaning optical oil-in-water sensor for an automatic water cutter, comprising a pipe, a first window, a second window, and a flushing assembly. Upon receiving a cleaning command, the flushing assembly sprays external high-pressure steam, high-pressure water, or high-pressure air through jet nozzles onto the end faces of the first and second windows, cleaning the oil stains on these surfaces. The removed oil flows downstream with the analyte in the pipe, preventing oil stains from obscuring the first and second windows, thereby making the optical oil-in-water sensor more accurate in detecting water quality at the water cutter site.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. At the same time, it should be understood that the specific embodiments described herein are merely used to explain the present utility model and are not intended to limit the present utility model.

[0020] like Figure 1 As shown, this utility model provides a self-cleaning optical oil-water sensor for an automatic water cutter, including an optical oil-water sensor body in the automatic water cutter and a flushing assembly disposed on the optical oil-water sensor body in the automatic water cutter. The optical oil-water sensor body in the automatic water cutter includes a pipe 11 for the passage of the sampled water to be measured or the oil-water mixture of the automatic water cutter, a first window 12 disposed on one side of the pipe 11, a second window 13 disposed on the other side of the pipe 11, and a mounting hole 14 penetrating the side wall of the pipe 11; the first window 12 and the second window 13 are stepped axial solid glass structures arranged symmetrically at intervals, preferably made of sapphire. Both the first window 12 and the second window 13 penetrate the side wall of the pipe 11, with one end located outside the side wall of the pipe 11 and the other end located inside the pipe 11, that is: the end face of the first window 12 and the end face of the second window 13 are arranged at intervals and both are disposed inside the pipe 11. The centers of the first window 12, the second window 13, and the mounting hole 14 are located on the same annular diameter of the pipe 11.

[0021] A flange 15, coaxial with the pipe 11, is connected to the inlet of the pipe 11, and a flange 16, coaxial with the pipe 11, is connected to the outlet of the pipe 11. The first window 12 and the second window 13 are coaxially arranged, and the center lines of both the first window 12 and the second window 13 are perpendicular to the center line of the pipe 11. The flanges facilitate connection to the pipeline to be tested by the water cutter, and the coaxial arrangement of the first window 12 and the second window 13 enables more accurate detection of the oil content in the extracted water.

[0022] The flushing assembly is installed in the mounting hole 14. The output end of the flushing assembly is provided with a jet nozzle for spraying and cleaning the end faces of the first window 12 and / or the second window. The input end of the flushing assembly is connected in sequence to a pump body (not shown in the figure) and a water supply unit (not shown in the figure) via a pipeline. A control device for controlling the flushing assembly is also provided. Both the pump body and the water supply unit are located outside the pipeline 11. During operation, after receiving a cleaning command from the control device, the flushing assembly can flush the end faces of the first window 12 and the second window through the jet nozzle to remove oil stains from their surfaces.

[0023] This embodiment provides two types of flushing assembly structures: a nozzle or a flushing seat. The nozzle can be used alone to perform high-pressure flushing on the end face of the window, or the flushing seat can be used to perform high-pressure flushing on the end face of the window, or both the nozzle and the flushing seat can be used simultaneously to perform high-pressure flushing on the end face of the window.

[0024] Option 1

[0025] like Figure 1-5 As shown, the flushing assembly includes a flushing seat 31 disposed on the side wall of the pipe 11. The flushing seat 31 is installed through the mounting hole 14 and fixed to the pipe 11 with screws. The flushing seat 31 is provided with an annular sealing groove 35 and a sealing ring is installed to form a sealing structure with the pipe 11. One end of the flushing seat 31 is provided with a flow channel 32 communicating with an external pipeline, and the other end is provided with a forked nozzle 33. The two branches of the forked nozzle 33 form a U-shaped structure 36. The two branches of the forked nozzle 33 are respectively provided with jet injection holes 34. One end of the jet injection hole 34 is connected to the flow channel 32, and the other end is respectively aligned with the first window 12 and the second window 13. High-pressure steam, high-pressure water, or high-pressure air passes through the flow channel 32 and the jet injection hole 34 to blow away the end face of the window, thereby removing the oil stains from the end face of the window.

[0026] Preferably, the distance between the two jet nozzles 34 gradually increases along the direction from the flushing seat 31 to the mounting hole 14. The high-pressure steam, high-pressure water, or high-pressure air ejected from the two jet nozzles 34 form an angle of 1-4° with the surfaces of the first window 12 and the second window 13, respectively. The ejected high-pressure steam, high-pressure water, or high-pressure air can act on the first window 12 and the second window 13 over a larger area, thereby improving the flushing efficiency of the flushing seat.

[0027] Option 2

[0028] like Figure 6 , 7 As shown, the rinsing assembly includes a nozzle 2. The body of the nozzle 2 is a straight rod-shaped tube with threads that mate with mounting holes. A hexagonal head 23 for rotating the body is also fixedly mounted on the body. One end of the nozzle 2 has a jet nozzle 21, and the other end has a flow channel 22 communicating with the jet nozzle 21. One end of the nozzle 2 passes through a mounting hole 14 in the side wall of the pipe 11 and is threadedly connected to the pipe 11 to spray and clean the end face of the window. The other end is connected to a pipeline to supply high-pressure steam, high-pressure water, or high-pressure air to rinse the end face of the window.

[0029] The jet nozzle 21 is flat-nozzle shaped. Two parallel jet nozzles 21 are provided at one end of the main body, respectively aligned with the first window 12 and the second window 13. The flow channel 22 is cylindrical. After the flow channel 22 is connected to the pipeline, high-pressure steam, high-pressure water, or high-pressure air is used to flush the end faces of the windows through the jet nozzles 21. To better flush the first window 12 and the second window 13, the exit direction of the jet nozzles 21 forms an angle of 1-4° with the surfaces of the first window 12 and the second window 13.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
