Description
Technical field
The utility model relates to a kind of valve tower, particularly a kind of big flux guide float valve tray.
Background technology
Valve tower is a kind of plated tower that grows up in recent decades.Compare with bubble column, its main feature is the plate efficiency height, and fluid resistance is little, and production capacity is big, and operating flexibility (promptly when the steam flow velocity changes, is unlikely to influence separative efficiency greatly in a big way.)。Simple in structure, cost is low, and can be used for the separation of material such as dirty, sticking.Therefore, be used widely very soon, become the main tower in chemical industry and the oil refining production.
The structure of valve tower is similar to bubble column.In valve tower, except that downspout, downflow weir are arranged, also have many macropores (general aperture is 39mm) on every layer of column plate, a float valve moving up and down is housed in every hole.The float valve that uses both at home and abroad has multiple model at present.F1 float valve, rectangle guide float-valve and trapezoidal guide float-valve are three kinds of used float valves of the most frequently used valve plate.F-1 type float valve is typical, the most frequently used model, and it is a circular valve block, and the periphery of valve block has downward-sloping edge.Three downward protuberances are arranged on the valve block, make valve block fall the slit that fashion can keep 2～3mm with column plate, to prevent owing to corrosion and column plate bonding and can not open.There are three " pin " hooks to insert in the perforate under the valve block, with the restriction float valve certain aperture arranged, and make it can not break away from valve opening.For circular valve plate, because gas blows out around float valve, not only there is gas-liquid between valve and the valve phenomenon that liquidates, and the gas that part blows out is opposite with the liquid flow path direction, form liquid dispersion, increase the resistance of liquid flow on the column plate, thereby caused gradient of liquid level to increase, reduced plate efficiency.Simultaneously and since when operation circular float valve rotation phenomenon, valve pin serious wear causes float valve to come off, thereby makes the column plate can not normal running.
For the rectangle guide float valve tray, though do not have the float valve obscission, for big flow intensity, as the liquid flowing strength of column plate greater than 60M
3During/m.h,, be difficult to eliminate fully the gradient of liquid level on the column plate though the rectangle guide float valve tray can reduce gradient of liquid level.For trapezoidal float valve, excessive to the motive force of liquid, form negative gradient of liquid level easily, influence the operating characteristics of column plate.
Kai Fa valve plate in recent years, the tradition arrangement mode of arranging can mainly be divided into two big classes: (1) "T"-shaped arrangement valve plate; (2) in-line arrangement guiding class valve plate.These two kinds of column plates have all solved some shortcomings that F1 type valve plate exists from identical or different approach, but still exist certain not enough.Successfully solved the inter-stage back-mixing as " T " row column plate, but gradient of liquid level exists still; The in-line arrangement guide float-valve is just in time opposite, and these deficiencies all affect the further raising of separating effect, pressure drop performance and treating capacity.
Summary of the invention
The utility model provides a kind of big flux guide float valve tray for solving the technical problem that exists in the known technology, and this column plate mass transfer flux is big, the efficient height.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of big flux guide float valve tray, comprise column plate with valve opening and the guide float-valve that is installed on the valve opening, guide float-valve comprises valve block, valve block is provided with the valve pin, and described valve block is by half elliptic, rectangle, the trapezoidal polygon of forming successively.
The edge of described valve block is provided with outwards outstanding arc tooth limit.
The planar structure of described valve block for connecting.
Direction along liquid stream on the described valve block has the tongue hole.
Described valve pin is three and is the valve pin that angular position is arranged that described valve pin is provided with through hole.
Two kinds of guide float-valves are installed on the described column plate, and the direction along liquid stream on a kind of valve block of guide float-valve has the tongue hole, the planar structure of the valve block of another kind of guide float-valve for connecting.
Described two kinds of guide float-valves are intervally arranged.
Advantage and the good effect that the utlity model has are: because the valve block of guide float-valve has adopted by half elliptic, rectangle, the trapezoidal polygonized structure of forming successively, effectively eliminated back-mixing and the gradient of liquid level on the column plate; Castellated edge has improved the decentralization of gas greatly, improves mass-transfer efficiency, optimizes the liquids and gases contact condition of column plate; Improve the percent opening on the column plate, plate efficiency and disposal ability are significantly improved, when realizing anti-clogging, reached the result of use of big flux.Column plate adopts the float valve open the tongue hole and not open the tongue hole to be intervally arranged and forms, reliable in structure, and disposal ability and operating flexibility improve greatly, and can improve the enlarge-effect of tower, and mass transport process is strengthened.Compare with F1 type valve plate, both had the guide float valve tray advantage, the pressure drop of column plate also can reduce 100-300Pa, and disposal ability has improved 15-35%, and mass-transfer efficiency can improve about 15%.
