Float Valve

Float valve is one of the tray structures widely used in China at present. It has outstanding excellent performance, and its main characteristics are:
â‘´ Large operating flexibility
As the valve plate can rise and fall freely, it can adapt to the change of air volume from big to small, and the air gap speed is almost constant. It can also maintain high separation efficiency in a wide operating range with frequent load changes.
⑵ High separation efficiency
In practical application, the tray efficiency can reach 60~70%, 10~15 higher than that of bubble cap tray, and it is still very high at low load. Due to the high efficiency, the product quality is improved accordingly.
(3) Large processing capacity
Because the arrangement of float valves is much more compact than that of bubble cap tower, the opening rate is increased. In addition, the air flow blows into the liquid level in the horizontal direction, so the entrainment of foam is low, which can improve the air flow and increase the production capacity. The production capacity is 20~40% higher than that of bubble cap tower.
(4) Pressure drop is small
The air flow through the float valve shrinks, expands and turns only once, and the pressure drop is lower than that of the bubble cap tray. The pressure drop of each tray in the atmospheric tower is only 3-5 mm Hg.
In addition, it has simple structure and low cost; Long service life, no fear of dirty materials; Convenient installation and use.
Performance characteristics of float valve tray:
(1) The processing capacity is smaller than tongue type, sieve plate, and larger than bubble cap tray;
(2) Large operational flexibility;
(3) The pressure drop of the dry plate is larger than that of the tongue type, the sieve plate tray is larger, the pressure drop is smaller than that of the bubble cap tray, and the liquid level gradient on the tray is smaller;
(4) The entrainment of fog is small;
(5) Simple structure and convenient installation.
