Function of float valve tray:
Both bubble cap plate and plate plate advantages, the most widely used.
Features: the production capacity of large operational flexibility, tower plate efficiency, gas pressure drop and liquid level fall is small, the cost is low. Expert tips: floating valve tray should not be easy to coke or the viscosity of the system.
Valve tray has valve holes opened and valve element equipped available to ride up and down within some proper scope. The circulation area between the floating valve and tray could be adjusted automatically along with the changes in gas load, so its available to maintain stable operations within a broad scope of gas loads. Gas may be blown out horizontally from the tray, so that the gas-liquid contact is of long time, the entrainment is small, and the fall of liquid level is also relatively small. Compared with bubble cap tray, floating valve tray has bigger processing capacity, lower pressure drop, and higher tray efficiency.
Type: Model F1 float valve tray, ADV float valve tray, U float valve tray , the diamond float valve tray , trapezoidal float valve ,Cross float valve
F1 valve tray :
F1 float valve: At present, F1 float valve is most extensively used, and includes light valve and heavy valve. Valve element and three valve legs are made as a whole, and around the valve element are three Initiative Spacing Pieces which can keep some certain clearance between the valve element and tray plate when the valve element is closed up. The Initiative Spacing Pieces make the interface between the valve element and tray plate very small to prevent the valve element from sticking to the tray plate, so that the valve element can rise smoothly when the gas increases. The circumambience of valve element inclines downwards and strengthens the turbulence action in the gas-liquid contact.
ADV Valve tray
ADV differential valve tray is based on the F1 float valve tray, inherits its advantages, and overcomes its disadvantages, and has carried on the innovation in the floating valve structure and the tower structure.. Adv tray through a comprehensive optimization, to improve production capacity at the same time, so that efficiency improve, reduce resistance, increase the flexibility of the operation the with excellent comprehensive properties, and comprehensively improve the technical level of the tower plate. Compared with the F1 type float valve tray: production capacity is increased more than 40 percent, more than 10% more efficient separation, large elasticity of operation 40% above, pressure drop about low 10%.
Rectangular float valve tray
The guide float valve is trapezoidal in shape, and rectangular floating valve used in combination to form combined guide float valve tower plate, combined guide float valve tower plate both guide rectangular floating valve tray and guide trapezoidal floating valve tray has the advantages to overcome the they both have their respective shortcomings, has wider application range and better operation performance. The same as the valve hole critical gas velocity of the combination guide valve tray and the valve tray under the corresponding conditions.
Fixed Valve Tray
The plate is on the board surface direct stamping valve body, valve body and a tray into a whole, main features: large production capacity, high tray efficiency, tray pressure drop is small, simple structure, low cost, especially suitable for in material from the poly distillation system.
Simple structure, low cost, small gas pressure drop, the upper liquid level drop is small, the production capacity and the plate efficiency are higher than the bubble cap tower plate. Disadvantages: small flexibility of operation, prone to clogging sieve hours, but as long as the design is reasonable, the larger aperture, coupled with proper operation, to overcome the shortcomings, obtain satisfactory tray efficiency.
Bubble cap Tray
One of the earliest mass transfer equipment.
The gas-liquid contacting element for bubble cap tray is bubble cap, which has round and groove-shaped structure forms. The bubble cap is installed above the chimney, and will not leak in conditions of proper installation and gas-liquid load, so the bubble cap tray is featured by stable operation and great flexibility. For structural reasons, the liquid level on the tray is relatively high, and two-phase contact is of long time. Therefore, the pressure drop is high, entrainment is increased, and the fall in the liquid level on the tray is relatively great, etc.
The advantage is that the leakage liquid phenomenon is not easy, and good operation elasticity, when the gas liquid has a big fluctuation, still can maintain almost constant board efficiency, the tower board is not easy to plug, is suitable for handling all kinds of materials. Disadvantages: the structure of the tower is complex, the cost is high, the liquid layer is thick, the gas flow diameter is winding, the pressure drop is large, the entrainment of fog is serious.
