[0031] The bottom end of the movable rotating shaft 14 is provided with a gear disc 7, the outer part of the gear disc 7 is provided with a gear, the bottom of one side of the gear disc 7 is inclined, the gear disc 7 is downward, when the bottom is impacted by gas, the gear disc 7 will rotate, and the components at the top of the gear disc 7 will rotate. Specific embodiment two:
[0033] Reference Figures 1-4 The soft material used by the flow guide 5, the fan blade 18 and the cleaning bristles 19 is a composite material of rubber and polyurethane, the rubber provides flexibility to adapt to different working conditions of swinging and rotating, and the polyurethane enhances wear resistance and prolongs service life.
[0034] The tower plate body 1 is designed in a stepped shape, the height difference of each step is 50mm, which facilitates the stratified flow of gas and liquid in different areas and improves the mass transfer efficiency. The diameter of the tower plate is adapted to the actual size of the tower body to ensure uniform distribution of gas and avoid excessive or insufficient gas velocity.
[0035] The thickness of the float valve 2 is 5mm, and the length and width dimensions are adapted to the size of the opening, which is slightly smaller than the diameter of the opening to ensure smooth lifting in the opening, and the maximum lifting height is 40mm.
[0036] The length of the deflector 5 is 60mm and the width is 20mm when it is unfolded, and it is completely hidden in the slot 9 when it is stored, the depth of the slot 9 is 25mm and the width is 22mm, which ensures that the deflector can move freely.
[0037] The L-shaped long side of the guide support arm 15 is 40mm and the short side is 20mm, the size of the sliding block 16 is tightly matched with the sliding groove 4, the depth of the sliding groove 4 is 10mm and the width is 15mm, the diameter of the fan blade 18 is 50mm and the thickness is 3mm, the length of the cleaning brush 19 is 10mm, which is uniformly distributed on the edge of the fan blade, the power of the vibrator is 10W and the frequency is 50Hz, which can effectively shake off the attached impurities.
[0038] A rubber sealing ring is installed at the contact edge of the float valve 2 and the opening 3 to prevent gas leakage and ensure that all the gas passes from below the float valve 2 to push the float valve 2 to work and improve the utilization rate of gas. The key connection is used at the clamping part of the movable rotating shaft 14 and the embedded disc 6 to ensure that they rotate synchronously, and a sealing sleeve is installed at the connection to prevent impurities from entering and affecting rotation.
[0039] In gas-liquid mass transfer equipment such as rectifying column, high-efficiency guide float valve tray plays a key role. When gas rises from below the tray, it first hits the gear disc 7, and due to the inclination of the gear disc 7 to one side of the bottom, the impact force of the gas makes it rotate around the shaft. The rotation of the gear disc 7 drives the top-connected movable rotating shaft 14, embedded disc 6 and fan blade 18 to rotate together. The fan blade 18 changes straight according to the principle of bamboo dragonfly in rotation, and the external cleaning brush 19 sweeps the impurities accumulated around and below the opening of the tray, preventing the opening from being blocked or affecting the flow of gas, while the vibrator works to further shake off stubborn impurities, ensuring that the gas passage is unobstructed,
[0040] As the gas flow increases, the pressure rises, and the gas enters below the opening 3 to push the float valve 2 upward. The guide support arms 15 on both sides of the bottom of the float valve 2 rise stably along the sliding groove 4 through the sliding block 16, ensuring that the float valve 2 rises vertically and avoids deviation or jamming. At this time, since the deflector 5 is no longer pressed by the opening wall, it expands within a range of 25° around the through column 11 and tilts to the top of one side under the action of its own gravity and gas flow. The deflector 5 in the shape of a wing directs the gas flow to a specific direction, making the gas evenly dispersed above the tray, enhancing the gas-liquid contact effect and promoting the mass and heat transfer process. The liquid flows from above the tray and fully mixes and contacts with the rising gas under the guidance of the deflector 5, realizing efficient separation of components. When the gas flow decreases, the float valve 2 falls back into the opening 3 under the action of its own gravity, and the deflector 5 is stored back into the slot 9, returning to the initial state and waiting for the next operation cycle.
[0041] In summary:
[0042] 1、In the device, the whole guiding float valve tray is designed ingeniously, and various components work cooperatively to effectively improve the gas-liquid mass transfer efficiency. The tray body 1 is in a ladder shape, and the unique structure combined with the layout of the openings 3 creates good conditions for the layered flow of gas and liquid. The opening parameters are accurately set to ensure uniform gas dispersion. The float valve 2 is made of lightweight and high-strength material, and is matched with the stable guiding structure composed of the L-shaped guiding support arm 15, the sliding block 16 and the sliding groove 4 to ensure smooth and vertical lifting and to avoid operation failure. The guide vane 5 is flexible and variable, and can be freely stored and expanded. The duck wing-shaped design skillfully guides the gas flow to optimize the gas-liquid contact. The fan blade 18 and the auxiliary cleaning component are a highlight. The soft composite material is flexible and wear-resistant. The impurities are rotated and cleaned under the principle of bamboo dragonfly. The vibrator provides power to completely clean the blockage. The inclined gear disc 7 is driven by gas to ensure self-cleaning and unobstructed gas passage.

[0043] 2、The efficient guiding float valve tray has excellent performance in the field of gas-liquid mass transfer. From the basic structure, the ladder architecture of the tray body 1 and the reasonable opening 3 planning lay the foundation for high efficiency, and different specifications and sizes are finely matched with actual needs. The float valve 2 is a key dynamic component, which is made of aluminum alloy material, is light and tough, responds to gas driving, and cooperates with the precisely designed slot 9 and the through column 11 to realize flexible regulation of the guide vane 5 to control the gas flow direction and expand the gas-liquid interaction area. The components associated with the bottom rotating base 13 are excellent, the movable rotating shaft 14 links the fan blade 18 and the cleaning brush 19, and uses the kinetic energy of gas to automatically clean impurities and maintain the cleanliness of the device. Stable connection design such as key connection and sealing treatment ensures long-term reliable operation. Whether it is the dynamic response under the impact of gas or the stable mass transfer of liquid flowing through, each link is closely linked to provide a valuable innovation example for the upgrading of tower equipment in the chemical, rectification and other industries, which is expected to significantly improve production efficiency and product quality.
