Abstract
Description
Technical Field
[0001] This utility model specifically relates to a filter for removing oil and water. Background Technology
[0002] Flue gas monitoring refers to the monitoring of the concentration and total emissions of gaseous pollutants and particulate matter emitted from air pollution sources.
[0003] In environmental monitoring, flue gas typically contains varying amounts of water and oil. When the water vapor content reaches a certain level, it will condense in the sampling probe and analyzer, while the oil will affect the subsequent data acquisition by the analyzer. Utility Model Content
[0004] The purpose of this invention is to provide an oil and water removal filter to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an oil and water removal filter, comprising a probe rod, a connector provided in the probe rod in the detection direction, a cavity opened inside the probe rod, an oil-blocking fiber provided in the cavity, and a first water-blocking filter and a second water-blocking filter respectively provided in the cavity and on both sides of the oil-blocking fiber by means of an installation assembly.
[0006] Preferably, the installation assembly includes fixing blocks disposed on the upper and lower sides of the first and second water-blocking filters, and the fixing blocks have inward grooves on the side facing the inner wall of the cavity.
[0007] Preferably, springs are provided on both the left and right sides of the groove, and a movable block is connected to one end of the two springs that are close to each other. The movable block extends through the groove opening to the outside of the fixed block and is connected to a limit plate.
[0008] Preferably, there are two limiting plates in each groove, and the two limiting plates are arranged in a mirror image.
[0009] Preferably, the groove has sliding grooves on both the upper and lower sides, and a sliding rod that slides along the length of the groove is provided in the sliding groove.
[0010] Preferably, the slide bar extends outside the slide groove and connects to the moving block.
[0011] Preferably, limiting grooves are formed on the upper and lower sides of the inner wall of the cavity.
[0012] The technical effects and advantages of this utility model are as follows: The oil and water removal filter has a cavity in which a first water-blocking filter, an oil-blocking fiber, and a second water-blocking filter are installed in sequence. The first and second water-blocking filters are die-cast and can achieve a water blocking efficiency of 99% by increasing the duty cycle. The oil-blocking fiber is 1-3μm and can effectively filter oil and gas. The third layer is the second water-blocking filter. During sampling, water and oil are filtered before the flue gas enters the sampling probe to ensure the accuracy of subsequent monitoring. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] To improve the accuracy of subsequent flue gas detection, refer to Figure 1 , Figure 2 and Figure 3 As shown, the device includes a probe 1, a connector 2 positioned in the detection direction of the probe 1, a cavity 3 inside the probe 1, an oil-blocking fiber 4 inside the cavity 3, and a first water-blocking filter 5 and a second water-blocking filter 6 respectively installed on both sides of the oil-blocking fiber 4 within the cavity 3 via mounting components. The first water-blocking filter 5, the oil-blocking fiber 4, and the second water-blocking filter 6 are installed sequentially inside the cavity 3. The first water-blocking filter 5 and the second water-blocking filter 6 are die-cast from molds. By increasing the duty cycle, the water-blocking efficiency can reach 99%. The oil-blocking fiber 4 is 1-3μm and can effectively filter oil and gas. The third layer is the second water-blocking filter 6. During sampling, water and oil are filtered before the flue gas enters the sampling probe to ensure the accuracy of subsequent detection.
[0020] For ease of installation of the first water-blocking filter screen 5 and the second water-blocking filter screen 6, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the installation assembly includes fixing blocks 7 disposed on the upper and lower sides of the first water-blocking filter 5 and the second water-blocking filter 6. The fixing blocks 7 have a groove 8 facing inward on the side facing the inner wall of the cavity 3. Springs 9 are disposed on the left and right sides of the groove 8. The two springs 9 are connected to a moving block 10 at one end close to each other. The moving block 10 extends through the opening of the groove 8 to the outside of the fixing block 7 and is connected to a limiting plate 11. When the first water-blocking filter 5 and the second water-blocking filter 6 are installed, the two limiting plates 11 are pressed closer to each other, which drives the two moving blocks 10 to move closer to each other. At this time, the springs 9 are stretched. As the limiting plates 11 are inserted into the limiting grooves, the limiting plates 11 lose pressure, the springs 9 deform, and the elastic potential energy reacts on the limiting plates 11. As the sliding rod 13 slides in the sliding groove 12, the two moving blocks 10 are driven away from each other, so that the two limiting plates 11 are inserted into the limiting grooves, thus completing the fixing of the first water-blocking filter 5 and the second water-blocking filter 6. Each groove 8 contains two limiting plates 11, which are mirror images of each other. The first water-blocking filter 5 and the second water-blocking filter 6 are installed by inserting the two limiting plates 11 into the limiting grooves. Sliding grooves 12 are provided on both the upper and lower sides of each groove 8. A sliding rod 13 is installed within each sliding groove 12, sliding along its length. The sliding rod 13 moves within the groove 12, both moving the moving block 10 and providing support, improving the stability and smoothness of the moving block 10 during movement. The sliding rod 13 extends outside the sliding groove 12 and connects to the moving block 10. Limiting grooves (not shown in the diagram) are provided on the upper and lower sides of the inner wall of the cavity 3. The first water-blocking filter 5 and the second water-blocking filter 6 are fixed by inserting the limiting plates 11 into these grooves, thus completing the filtration process. With a simple overall structure, it is suitable for working conditions with high humidity and high oil and gas (e.g., printing and dyeing, chemical industry), and has high filtration efficiency, ensuring the accuracy of subsequent sample testing.
[0021] In use, firstly, by pressing the two limiting plates 11 closer together, the two moving blocks 10 are driven to move closer together. At this time, the spring 9 is stretched. As the limiting plates 11 are inserted into the limiting groove, the limiting plates 11 lose pressure, the spring 9 deforms, and the elastic potential energy reacts to the limiting plates 11. As the sliding rod 13 slides in the sliding groove 12, the two moving blocks 10 are driven to move away from each other, so that the two limiting plates 11 are inserted into the limiting groove, thus completing the fixation of the first water-blocking filter 5 and the second water-blocking filter 6. During sampling, before the flue gas enters the sampling probe, it can first enter the cavity 3 through the connector 2 to filter water and oil.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
