Early fifties has been developed F1 Round float valve column plate, and its bulking property all has very big advantage in a very long time.Particularly ripple packing of structured packing has appearred in the sixties, makes the application of packed tower more extensive.Its remarkable advantage is that separating power is higher, and flux is bigger, and pressure drop is less, for the old tower technology transformation that improves treating capacity and separation purity, replaces column plate to have very big attraction with new packing.But the once investment of employing new packing is big (the especially tower of major diameter, many side lines), and the production occasion of burn into coking, dirt is being arranged, and application is restricted.So people begin to seek with new interest the breakthrough of plate column again, with the big flux that adapts to increasing major diameter rectifying column, high efficiency requirement.
At present, the novel column plate of having developed has reached tens kinds, has concluded out, and column plate can be divided into two types: i.e. fixedly column plate and valve plate.Though the existing fixed column plate has advantage of simple structure, operating flexibility is little aborning, leaks greatly, and mass-transfer efficiency is low; Though valve plate has had bigger improvement on operating flexibility, in long period of operation, valve body is prone to rotation and comes off; Gradient of liquid level on the column plate is big, makes gas skewness on liquid flow direction, be prone to produce the liquid excessive leakage at the column plate arrival end, is prone to produce that liquid is excessive to be carried secretly at the port of export, and the column plate arch area is violated and mixed seriously, has had a strong impact on the efficient of column plate.
Summary of the invention
The utility model purpose is the comprehensive fixing advantage of column plate and valve plate; Overcome the shortcoming of solid valve column plate; It is a kind of new and effective, operating flexibility broad; And strengthened the mechanical strength of column plate, and reduced the cost of extra float valve, saved the material resources of manufacturing installation and a kind of efficient valve tower tray admittedly of manpower.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of efficient valve tower tray admittedly includes column plate, is evenly distributed with several solid valves on the said column plate.
As preferably, said solid valve includes valve gap, and column plate is provided with opening, and valve gap is positioned at the top of opening, and the side of valve gap dual-side and column plate opening is fixed.
As preferably, said valve gap is trapezoidal.
As preferably, the side that said valve gap arches upward is curved.
As preferably, said valve gap and column plate are one-body molded.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
(1) the solid valve of KDG adopts solid valve to combine with column plate.Make the tower plate structure form simple, manufacturing processing and installation and maintenance are simpler.Gu the mechanical strength of column plate has more been strengthened in the existence of valve, and reduces the cost of extra float valve, saved and made material resources and the manpower of installing.
(2) valve body is trapezoidal in the solid valve tower tray of KDG.In operation; Gas blows out from the valve gap both sides; Constitute acute angle with the flow direction less than 90 °; Therefore the liquid on the column plate is had certain guiding impetus, this is to improving liquid-flow state, reduce backmixing of liquid phase, improve column plate flow uniformity good effect is all arranged, thereby improves the disposal ability and the efficient of column plate greatly.
(3) the solid valve valve gap of KDG adopts arc limit structure.The air-flow that ejects from valve seam makes gas-liquid that bigger attaching space arranged through covering dispersion.Certain radian reduces gas and directly upwards blows, and effectively reduces mist entrainment, and the particle of the deposition on the tray deck is had certain purging effect.
(4) suitably improve downspout.Increase the bubbling area, improve the column plate mass transfer and effectively distinguish; Increased flow channel for liquids length simultaneously, reduced the impact of liquid column plate; The commute foaming system has certain froth breaking effect, has strengthened adaptive capacity, the interior liquid handling capacity of downspout is strengthened greatly, thereby improved disposal ability.
(5) adopt that column plate is gone into, the exit weir technology.Can slow down column plate inlet hydraulic shock as column plate inlet weir; Improve column plate inlet flow and distribute, improve plate efficiency, simultaneously to playing the downcomer seal effect; Can improve on the column plate liquid holding zone as the tray outlet weir flows; Improve downspout gas-liquid separation ability, improve the downspout disposal ability, reduce requirement the time of staying.
