Description

Technical Field

[0001] The utility model relates to the technical field of tower trays, in particular to a fluid-stable floating valve tower tray. Background Art

[0002] The floating valve tray has a valve hole of a certain shape (circular or rectangular), and the hole is equipped with a valve disc that can float up and down, which is circular, rectangular, disc-shaped, etc., thus forming different types of floating valve trays. The floating valve tray has become the most widely used tray because of its excellent comprehensive performance (large production capacity, large operating flexibility, high tray efficiency, low manufacturing cost, etc.). The floating valve tray is the most commonly used tray. It has many square or circular holes on the tray, and each hole has a valve disc. The gas pushes the valve disc upward through the valve hole and shoots out horizontally. When passing through the liquid layer, the gas and liquid phases are in a foam state for heat and mass transfer. Since the valve disc opening can change with the gas velocity, the valve disc can be automatically closed under the action of gravity at low gas velocity, reducing leakage, so it has the advantages of high efficiency and high flexibility; and it has a simple structure, low cost, and high processing capacity.

[0003] At present, the gas of the existing float valve tray is mostly ejected directly from the side, which makes the gas dispersed unevenly, makes the fluid unstable, is not convenient for the gas to be ejected more dispersedly and evenly, and has low production efficiency. Utility Model Content

[0011] Preferably, four valve legs are arranged in a circular array, and a plurality of air holes are arranged in a linear array.

[0012] Beneficial Effects

[0013] In the utility model, a valve cover, a diverter groove, an exhaust groove and an air vent are adopted. Since the shape of the valve cover is set to be umbrella-shaped, the airflow enters the valve cover and flows to the top of the valve cover in a concentrated manner, and then is diverted through the diverter groove to avoid the concentrated discharge of the airflow, and the airflow is dispersed and discharged through the exhaust groove. The airflow forms a vortex in the exhaust groove, so that the airflow is sprayed out like mist, so that the airflow is sprayed out more dispersedly and evenly, and the fluid is more stable. In addition, air vents are provided on the surface of the valve leg so that the airflow can also be discharged through the air vents, so that the airflow is effectively dispersed, gas-liquid contact is convenient, and production efficiency is improved.

Four, the guide block 10 is guided in the guide groove 5, and the float valve is prevented from rotating during the rising process, so that the float valve and the valve hole 4 produce friction, thereby improving the stability of the float valve.

[0024] When the airflow flows from bottom to top, the float valve moves upward, and at the same time, the guide block 10 moves upward in the guide groove 5.

The air flow forms a vortex in the exhaust groove 8, so that the air flow is sprayed out like mist, so that the air flow is more dispersed and evenly sprayed, and the fluid is more stable. In addition, the air vent 11 is opened on the surface of the valve leg 9, so that the air flow can also be discharged through the air vent 11, so that the air flow is effectively dispersed, gas-liquid contact is convenient, and production efficiency is improved.
