Description

Technical Field

[0001] This utility model relates to the field of floating valve tray technology, and in particular to a floating valve tray with adjustable liquid flow rate. Background Technology

[0002] According to Chinese Patent Publication No. CN110327650A, a floating valve tray for petrochemical towers includes a tray, mounting holes, and floating valves. The tray has several vertically penetrating mounting holes, and floating valves are installed in these holes. Each floating valve includes a valve top cover, valve legs, a valve top outlet, and side outlets. The valve top cover has several valve top outlets on its upper part and several side outlets along its outer edge. The valve legs are located at the lower part of the valve top cover, with one end of the valve legs furthest from the valve top cover positioned below the tray. Compared to existing technologies, this invention provides a floating valve tray for petrochemical towers with a reasonable structure. By installing vertically movable floating valves in the mounting holes of the tray, the floating valves rise when the air velocity in the mounting holes is high and descend due to their own weight when the air velocity is low. When the floating valves are lifted by the airflow, the multiple valve top outlets and side outlets on the valve top cover effectively stabilize irregular airflow.

[0003] Technical problems: When the existing float valve enters the liquid layer, there will be impurities in the liquid, which will cause the float valve to handle the airflow poorly, resulting in uneven airflow dispersion and insufficient gas-liquid contact. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a floating valve tray with adjustable liquid flow rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a floating valve tray with adjustable liquid flow rate, comprising a tray plate, clamping blocks on both sides of the tray plate, a buffer plate on the surface of the tray plate, filter holes uniformly opened on the surface of the buffer plate, absorbent cotton inside the filter holes, and the interior of the clamping blocks being movably connected to the bottom surface of the buffer plate.

[0006] Preferably, the tray has an outlet on one side and an inlet on the other side, and the top surface of the tray has evenly spaced central holes.

[0007] Preferably, an upper pressure rod is provided inside the central hole, and a pressure plate is movably connected to the top end of the upper pressure rod.

[0008] Preferably, the tray plate has a pad block inside, and the surface of the pad block is uniformly provided with a lower pressure rod, and the bottom end of the upper pressure rod is movably connected to the interior of the lower pressure rod.

[0009] Preferably, the bottom surface of the pad block is uniformly provided with air bladders.

[0010] Preferably, a float valve is fixedly connected to the top surface of the pressure rod, and a connecting spring is provided on the surface of the float valve. One end of the connecting spring is fixedly connected to the top inner surface of the tray plate.

[0011] Preferably, a fixing block is fixedly connected to the bottom surface of the outlet.

[0012] Beneficial effects

[0013] In this invention, absorbent cotton is used to filter the liquid entering the tray through the filter holes on the surface of the buffer plate. The absorbent cotton can also adsorb foreign matter in the liquid, which facilitates full contact between gas and liquid. This allows the float valve to enter the liquid layer without impurities, making the float valve ideal for handling the airflow, with uniform airflow dispersion and sufficient gas-liquid contact.

[0014] In this invention, a connecting spring is used to push the float valve upward with gas and then press it downward. The lower end of the float valve contacts the top of the tray, facilitating liquid-gas mixing and thus providing a larger contact space between the gas and liquid, effectively improving the efficiency and production capacity of the tray.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-4 A floating valve tray with adjustable liquid flow rate includes a tray plate 1, with clamping blocks 6 on both sides of the tray plate 1, a buffer plate 16 on the surface of the tray plate 1, filter holes 7 evenly distributed on the surface of the buffer plate 16, absorbent cotton 8 inside the filter holes 7, and the interior of the clamping blocks 6 being movably connected to the bottom surface of the buffer plate 16.

[0025] One side of the tray plate 1 is provided with an outlet 2, and the other side of the tray plate 1 is provided with an inlet 4. The top surface of the tray plate 1 is evenly provided with a central hole 3. An upper pressure rod 9 is provided inside the central hole 3. The top of the upper pressure rod 9 is movably connected to a pressure plate 5. The inside of the tray plate 1 is provided with a pad block 14. The surface of the pad block 14 is evenly provided with a lower pressure rod 12. The bottom end of the upper pressure rod 9 is movably connected to the inside of the lower pressure rod 12. The bottom surface of the pad block 14 is evenly provided with an air bladder 13. The top surface of the lower pressure rod 12 is fixedly connected with a float valve 11. The surface of the float valve 11 is provided with a connecting spring 10. One end of the connecting spring 10 is fixedly connected to the top inner surface of the tray plate 1. The bottom surface of the outlet 2 is fixedly connected with a fixing block 15.

[0026] When in use, when the float valve 11 moves down, the pressure plate 5 moves down. When the liquid flows at the top of the tray 1, some of it will flow into the interior of the tray. The pressure plate 5 is moved down by the downward pressure of the upper pressure rod 9, so that the liquid flowing into the interior of the tray splashes up and mixes fully with the gas, and then is discharged downward through the outlet 2. When the float valve 11 moves up, the connecting spring 10 pulls the pressure plate 5 up to its original position, so that liquid can flow into the interior of the tray. Specific Implementation Example 2:

[0028] Reference Figure 1-4 A floating valve tray with adjustable liquid flow rate, based on the basic structure in Specific Embodiment 1, further solves the problem that the tray plate 1 and the floating valve 11 are prone to corrosion due to frequent contact with gas and liquid. In order to improve their corrosion resistance, a wear-resistant and corrosion-resistant coating, such as a nickel plating layer, can be added to the surface of the tray plate 1 and the floating valve 11.

[0029] In summary:

[0030] 1. Adsorbent cotton 8 is used to filter the liquid entering the tray through the filter holes 7 on the surface of the buffer plate 16. The adsorbent cotton 8 can also adsorb foreign matter in the liquid, which facilitates full contact between gas and liquid. This allows the float valve 11 to enter the liquid layer without impurities in the liquid, making the float valve 11 ideal for handling the airflow, with uniform airflow dispersion and full gas-liquid contact.

[0031] 2. A connecting spring 10 is used to push the float valve 11 upward through gas, and the connecting spring 10 pushes the float valve 11 downward. The lower end of the float valve 11 contacts the top of the tray plate 1, which facilitates liquid-gas mixing. This allows for a larger contact space between gas and liquid, effectively improving the efficiency and production capacity of the tray.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
