Description

Technical Field

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

[0002] A tray for a nitrogen washing tower, disclosed in Chinese Patent No. CN213556252U, includes a tray and a filter plate. The tray has an opening for wash water to fall and mounting holes. A filter plate cover is detachably connected to the mounting holes. A first overflow plate and a second overflow plate are fixedly connected to the tray. The second overflow plate is located on the side of the filter plate facing the opening. A weir is formed between the second overflow plate and the first overflow plate, and both sides of the second overflow plate extend towards the two surfaces of the tray. The mounting holes are located between the first and second overflow plates. Multiple overflow pipes are inserted into and fixed to the filter plate. A bubble cover is detachably connected to the opening edge of each overflow pipe facing the weir, and the opening edge of the bubble cover is located inside the weir. This application offers the advantage of relatively convenient replacement.

[0003] The above-mentioned documents and existing technologies have the following problems: the liquid distribution in the existing trays is uneven, the gas-liquid contact is insufficient, and when the pressure inside the tank is high, it is difficult to effectively control the pressure inside the tank, which can easily lead to dangerous situations such as overpressure or even explosion, seriously affecting production safety and equipment life. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable liquid distribution tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable liquid distribution tray, comprising a tray body, a valve hole and a dispersion groove on the surface of the tray body, a valve cover on the surface of the valve hole, a sealing port on the surface of the valve cover, a rotating rod on the surface of the valve cover, a torsion spring on the surface of the rotating rod, a connecting plate on the surface of the rotating rod, a sealing cover on the side of the connecting plate, and a vent hole on the surface of the sealing cover.

[0006] Preferably, the bottom surface of the valve cover is provided with valve legs, and multiple valve legs are arranged in a circumferential array.

[0007] Preferably, the surface of the valve leg is provided with venting grooves, and multiple sets of venting grooves are arranged in a circumferential array.

[0008] Preferably, the surface of the valve leg is provided with a limiting block, and multiple limiting blocks are arranged in a circumferential array.

[0009] Preferably, the valve holes are arranged linearly and equidistantly, and the multiple dispersion grooves are disposed on the surface of the tray body.

[0010] Preferably, the shape and position of the sealing cap correspond to the sealing opening, and the vent holes are arranged in a circumferential array on the surface of the sealing cap.

[0011] Preferably, the shape of the valve leg is adapted to the valve hole, and the shape and position of the limiting block are adapted to the valve hole.

[0012] Beneficial effects

[0013] This invention employs a dispersion tank, a torsion spring, a sealing cap, and a vent. The unique structure of the dispersion tank allows the liquid to be evenly dispersed on the tray, avoiding the problem of uneven liquid distribution in traditional trays and greatly increasing the gas-liquid contact area. The combination of the torsion spring and the sealing cap cleverly solves the problem of pressure regulation inside the tank. When the pressure inside the tank is normal, the sealing cap remains tightly closed under the action of the torsion spring. However, once the pressure inside the tank is high, the gas pressure overcomes the elasticity of the torsion spring and pushes the sealing cap open, allowing the gas to be quickly discharged through the sealing port. This effectively avoids overpressure inside the tank and reduces the risk of equipment damage and potential safety hazards caused by pressure issues. At the same time, the vent allows gas to flow out from multiple small holes. According to the principles of fluid mechanics, the gas velocity increases and is divided into multiple small streams when passing through the small holes. This refined gas can better contact the liquid, increasing the gas-liquid contact area and contact opportunities. Attached Figure Description

[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 1-5 An adjustable liquid distribution tray includes a tray body 1, which supports the installation and fixation of other components. The surface of the tray body 1 has valve holes 2, multiple valve holes 2 arranged linearly and equidistantly, providing an upward channel for gas, allowing gas to enter from below the tray body 1 to above it, contacting the liquid and transferring mass and heat. The surface of the tray body 1 also has dispersion grooves 3, multiple of which are arc-shaped, allowing liquid to splash and disperse from all directions. This unique structure ensures that liquid falling into these grooves... The liquid can be dispersed to achieve uniform distribution on the tray body 1. By dispersing the liquid into smaller droplets or thinner liquid layers, the gas-liquid contact area is greatly increased, providing more favorable conditions for the mass transfer process and improving the separation efficiency and reaction effect of the tray body 1. The surface of the valve orifice 2 is provided with a valve cover 4, which cooperates with the valve orifice 2 to control the flow rate and direction of the gas through the valve orifice 2 to a certain extent. By its own opening and closing state and its relative position to the valve orifice 2, it can adjust the rising speed and distribution range of the gas, affecting the intensity and uniformity of the gas-liquid contact to meet different process requirements.

[0025] A sealing port 12 is provided on the surface of the valve cover 4, and a rotating rod 10 is provided on the surface of the valve cover 4. The rotating rod 10 serves as a connecting component between the valve cover 4 and the sealing cover 8. Through cooperation with the torsion spring 11, it realizes the rotation and opening / closing action of the sealing cover 8. The rotating rod 10 is provided with a torsion spring 11. Under normal operating conditions, the torsion spring 11 provides sufficient elastic force to the sealing cover 8, making it press tightly against the sealing port 12 to maintain a sealed state. The magnitude and characteristics of its elastic force are designed to effectively resist the effect of gas pressure on the sealing cover 8 within a certain pressure range, ensuring the normal operation of the system. When the pressure inside the tank increases to a certain level, the pressure of the gas on the sealing cover 8 exceeds the elastic force of the torsion spring 11, and the torsion spring 11 deforms, allowing the sealing cover 8 to open, thereby realizing... The automatic adjustment of the tank pressure is achieved by a connecting plate 13 on the surface of the rotating rod 10, with a sealing cover 8 on the side of the connecting plate 13. The shape and position of the sealing cover 8 correspond to the sealing port 12. When the tank pressure is normal, the sealing cover 8 is tightly fitted to the sealing port 12 under the action of the torsion spring 11, ensuring that the gas and liquid inside the tray body 1 flow according to the predetermined path and method, maintaining the sealing and stability of the system. When the tank pressure rises abnormally, the gas pressure overcomes the elastic force of the torsion spring 11 and pushes the sealing cover 8 to open, making the sealing port 12 one of the channels for rapid gas discharge. Together with the venting groove 6, it quickly reduces the tank pressure, effectively preventing overpressure, protecting the equipment from damage caused by excessive pressure, and reducing the risk of safety accidents.

[0026] The surface of the sealing cap 8 is provided with vent holes 9, which are arranged in a circumferential array on the surface of the sealing cap 8. Under normal operating conditions, when the gas flows out through these small holes, according to the principle of fluid mechanics, the flow rate increases and is divided into multiple small gas streams. This refined gas can better contact the liquid, increase the gas-liquid contact area and contact opportunities, improve mass transfer efficiency, and optimize the working performance of the tray body 1. When the pressure inside the tank fluctuates, the vent holes 9 can also play a certain role in pressure balancing. Even when the sealing cap 8 is not fully opened, the gas can slowly circulate and exchange through the vent holes 9, which helps to maintain the relative stability of the internal pressure of the tray body 1 and reduce the adverse effects of sudden pressure changes on the gas-liquid contact and mass transfer process.

[0027] The bottom surface of the valve cover 4 is provided with valve legs 5, and multiple valve legs 5 are arranged in a circumferential array. The surface of the valve legs 5 is provided with venting grooves 6, and multiple sets of venting grooves 6 are arranged in a circumferential array. The main function of the valve legs 5 is to support the valve cover 4 so that it can be stably positioned above the valve hole 2. At the same time, the venting grooves 6 on the surface of the valve legs 5 provide additional flow channels for gas, which helps the gas to be evenly distributed and flow smoothly under the valve cover 4, further optimizing the gas-liquid contact effect and improving the overall performance of the tray body 1. The surface of the valve legs 5 is provided with limiting blocks 7, and multiple limiting blocks 7 are arranged in a circumferential array. The shape of the valve legs 5 is adapted to the valve hole 2, and the shape and position of the limiting blocks 7 are adapted to the valve hole 2. The limiting blocks 7 can play a limiting role to prevent the valve cover 4 and valve legs 5 from detaching from the valve hole 2 under the action of gas flow or other external forces, maintaining the normal working state of the tray body 1, and ensuring the stability and reliability of the gas-liquid contact and mass transfer process.

[0028] During operation, the liquid first enters the tray body 1. The dispersion tank 3, with its unique structure, causes the liquid to splash and disperse in all directions, forming smaller droplets or thinner liquid layers that are evenly distributed on the tray body 1. This significantly increases the gas-liquid contact area, creating favorable conditions for the mass transfer process. Simultaneously, gas rises from the valve orifice 2 on the tray body 1. The valve cover 4, in conjunction with the valve orifice 2, adjusts the gas rising speed and distribution range according to actual process requirements through its opening / closing state and relative position to the valve orifice 2, thus affecting the gas-liquid contact strength and uniformity. Under normal operating conditions, the torsion spring 11 provides elasticity to the sealing cover 8, making... It fits tightly against the sealing port 12 of the valve cover 4 to maintain the system's airtightness. Gas flows out through the vent holes 9 arranged in a circular array on the sealing cover 8, with the flow rate increasing and becoming finer, allowing for better contact with the liquid. Furthermore, the vent holes 9 can also play a certain role in pressure balancing when pressure fluctuates. When the pressure inside the tank rises abnormally, the gas pressure overcomes the elastic force of the torsion spring 11 to push the sealing cover 8 open. The sealing port 12 and the vent groove 6 on the valve leg 5 together serve as a rapid gas discharge channel, quickly reducing the pressure inside the tank, preventing overpressure, ensuring the stable operation of the entire device under various working conditions, and guaranteeing the efficient, stable, safe, and continuous operation of the gas-liquid contact and mass transfer process. Specific Implementation Example 2:

[0030] An adjustable liquid distribution tray, based on the basic structure in Specific Embodiment 1, further discloses the following structure: a guide block can be provided on the outer wall of the valve leg 5, and a guide groove is provided on the inner wall of the valve hole 2. The guide block slides within the guide groove, preventing the valve cover 4 and the valve leg 5 from rotating during lifting and lowering, reducing friction between components, avoiding component damage that may be caused by long-term wear, ensuring stable operation of the equipment, and reducing the maintenance and replacement costs of the equipment.

[0031] In summary:

[0032] 1. The system employs a dispersion tank 3, a torsion spring 11, a sealing cap 8, and a vent 9. The unique structure of the dispersion tank 3 allows the liquid to be evenly dispersed on the tray body 1, avoiding uneven liquid distribution and greatly increasing the gas-liquid contact area. The combination of the torsion spring 11 and the sealing cap 8 cleverly solves the problem of pressure regulation inside the tank. When the pressure inside the tank is normal, the sealing cap 8 remains tightly closed under the action of the torsion spring 11. However, once the pressure inside the tank is high, the gas pressure overcomes the elastic force of the torsion spring 11 and pushes the sealing cap 8 open, quickly discharging the gas through the sealing port 12. This effectively avoids overpressure inside the tank, reducing the risk of equipment damage and potential safety hazards caused by pressure issues. At the same time, the vent 9 allows gas to flow out from multiple small holes. According to the principles of fluid mechanics, the gas velocity increases and is divided into multiple small streams when passing through the small holes. This refined gas can better contact the liquid, increasing the gas-liquid contact area and contact opportunities.
