Description
Technical field
The present invention relates to chemical industry gas-liquid mass transfer (contact) equipment field, and in particular to a kind of new valve plate.
Background technology
In Chemical Manufacture, rectifying is that extremely wide operation is applied during chemical separating is operated, and the circle of prior art is floated
There is following defect in valve tower tray：Because float valve valve leg is movable, in practical operation, it is easy to rotate, cause valve leg
Serious wear, valve dislocation；When mounted, two valve leg bendings therein are fixed in the valve opening on tower tray, or
Person first installs the method being rotated by 90 ° again, adds workload, reduces production efficiency.The passage of other prior art is water
Flat setting, gas level direction is contacted after coming out with liquid, and mass-transfer efficiency is not high.Current valve plate is larger in gas flow
When, float valve lifting height is larger, only has space between valve block and column plate, and gas is when thus space is blown out on column plate
Larger bubble is formed in liquid, gas accumulates relatively small with liquid contact surface, and mass transter is less efficient.
Therefore, how to solve these problems, it has also become those skilled in the art's technical barrier urgently to be resolved hurrily.
The content of the invention
The present invention, there is provided a kind of new valve plate, is solved above-mentioned for the deficiencies in the prior art
Technical problem.
To achieve these goals, the present invention provides following technical scheme：A kind of new valve plate, including float valve
And column plate, the float valve include bonnet, valve cylinder and valve seat, the bonnet be open circles frustum structure, bonnet crown center set
Downward has externally threaded projection, and bonnet sidepiece, which is set, sets port lid on the outside of one number service stomata, one number service stomata；The valve cylinder
For hollow cylindrical structure, two ends inner side sets internal thread, and valve cylinder sidepiece is provided with No. two passages；The valve seat is hollow loudspeaker
Shape structure, its diameter gradually increases from top to bottom, and top, which is set, upward has externally threaded raised cylinder；The bonnet, valve
Cylinder and valve seat threaded connection；Valve opening is uniformly arranged on the column plate, the valve opening edge is set to the arc to hole center curvature,
The float valve is arranged in valve opening.
During above-mentioned installation, valve cylinder upper end first connects with the downward of bonnet crown center setting with externally threaded projection screw thread
Connect, bonnet passes through valve opening, it is then upward with externally threaded by what is set at the top of valve cylinder lower end and valve seat from the downside of column plate
Raised cylinder threaded connection, whole mounting means closely, will not loosen under liquid phase and the effect of the flexible external force of air-flow.
Above-mentioned middle bonnet is open circles frustum structure, and valve cylinder is hollow cylindrical structure, and valve opening edge is set into hole
The arc of heart bending, float valve under static state, forms certain space, it is to avoid because of shape with the valve opening outer rim top half of column plate
Occurs adhesive attraction into negative pressure；When float valve is raised in buoyancy, valve seat and valve opening outer rim the latter half can be made complete
Laminating, reduces the abrasion caused by collision, and effectively reduce noise.
Above-mentioned middle bonnet and valve-seat diameter maximum are all higher than the diameter of valve opening.
The new valve plate operation principle is that, when air-flow is smaller, port lid is opened, gas from the passage of valve seat successively
By the one number service stomata outflow of the center-aisle and bonnet of valve cylinder, the wherein folding degree of port lid and air-flow size is into positive
Close；When air-flow is larger, float valve rises, and port lid is opened, and gas is simultaneously from one number service stomata and No. two passage outflows, with column plate
On liquid phase occur mass transfer exchange.
It is preferred that, the one number service stomata is uniformly distributed along the bonnet sidepiece conical surface, makes air-flow to the active force of float valve bonnet
Uniformly, it is to avoid float valve run-off the straight.
It is preferred that, the one number service stomata is obliquely, it is furthermore preferred that the angle of the one number service stomata and horizontal plane
For 30-60 °, air-flow is set to be come out from the angle of obliquely downward, the initial movement track of the bubble of formation is lower parabolic, it is to avoid
Part bubble is come back in one number service stomata, hence it is evident that increase gas-liquid mass transfer distance, improves mass-transfer efficiency.
It is preferred that, No. two passages are uniformly distributed along valve cylinder sidepiece, make air-flow uniform to the active force of float valve valve cylinder,
Avoid float valve run-off the straight.
It is preferred that, No. two passages are obliquely, it is furthermore preferred that the angle of No. two passages and horizontal plane
For 30-60 °, air-flow is set to be come out from the angle of obliquely downward, the initial movement track of the bubble of formation is lower parabolic, it is to avoid
Part bubble is come back in No. two passages, hence it is evident that increase gas-liquid mass transfer distance, improves mass-transfer efficiency；No. two passages are supreme
And it is lower in multiple rows of setting, air-flow can be made further to be dispersed into numerous little airflows, more minute bubbles are formed, increase gas-liquid connects
Contacting surface is accumulated.
It is preferred that, the valve cylinder is identical with the transverse gage of valve seat wall, makes valve cylinder and the current path of valve seat formation suitable
Freely, gas-flow resistance is reduced.
It is preferred that, the conical surface bottom of the bonnet sets Flexible Connector, and the other end of Flexible Connector is connected with column plate,
Further increase the firmness of float valve, it is to avoid float valve rotates under the external application effect of liquid phase and departs from column plate, while energy
Float valve is enough set to revert to original position under the buoyancy of airless, in time.
It is furthermore preferred that the Flexible Connector is spring, quantity is two, pulling force is more balanced, and float valve is more consolidated.
Compared with prior art, the present invention has advantages below：The float valve structure is simple, reasonable in design, easy for installation, mill
Damage few, noise is low, it is not easy to come off, and float valve lifting heights can be adjusted at any time according to air-flow size, there is provided obliquely one
Number passage and No. two passages, make bubble be uniformly dispersed, gas-liquid mass transfer distance, and contact area is big, mass transter efficiency high, fit
It is wide with scope, it is with a wide range of applications.
