Abstract
The utility model discloses a tower plate for a guide bridge valve, which is composed of the guide bridge valve and a valve hole plate, wherein the valve hole plate is provided with bridge-shaped valve holes; the guide bridge valve comprises a valve sheet, a valve leg, flanging and a guide hole; the guide bridge valve is arranged in the bridge-shaped valve hole and can be arranged in the bridge-shaped valve hole in an up and down floating mode by the flanging; the front end and the back end of the valve sheet and the bridge-shaped valve hole form a strip shape, and the center part forms an arc shape or a circle shape. Because the special structure of the guide bridge valve, the utility model adopts the advantages that circle-shaped float valves are uniformly arrayed on the tower plate and strip-shaped float valves can effectively eliminate the returning and mixing on the tower plate; the tooth-shaped edge of the utility model improves the opening and closure performance of the float valve, an air channel is refined, the contact condition of liquid and gas of the tower plate is optimized, the opening rate on the tower plate is increased and the efficiency of the tower plate and the treatment capability is obviously increased.
Description
Technical field
The utility model relates to a kind of oil refining, chemical industry equipment inner member, specifically relates to a kind of valve plate.
Background technology
Valve plate is one of most important equipment during chemical industry, oil refining are produced, and has a wide range of applications industrial.It can make closely contact between gas (vapour) the liquid two-phase, reaches the purpose of interphase mass transfer and heat transfer, and unit operations common, that can finish in valve tower has mass transfer operations such as rectifying, absorption, desorb.
Valve plate float valve commonly used mainly contains circular and two kinds of bar shapeds.Circular float valve is because structural characteristics can be arranged in tower equably, but because gas blows out from circumference, the direction that the part gas blows out is opposite with liquid flow path direction on the column plate, has caused the interior back-mixing of tower, has reduced plate efficiency; Simultaneously, liquid flow needs motive force in the tower, and the liquid level drop of this source and the liquid-inlet end and the port of export because the existence of liquid level drop makes interior gas of tower and liquid distribution inhomogeneous, has increased pressure drop, has reduced plate efficiency simultaneously; Circular float valve is in operation owing to rotate, and the valve leg weares and teares easily, and float valve easily comes off.Though rectangular valve float valve does not in operation rotate, reliable in structure is obvious to blowing phenomenon between the float valve owing to most gases blow out from the float valve side, causes bigger liquid foam entrainment easily, influences plate efficiency; The common length and width of rectangular valve is than big, and horizontal and vertical can not evenly arranging caused the interior vapour-liquid contact of tower inhomogeneous, and supernatant layer and froth bed instability have influenced the further raising of tower disposal ability in the tower.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned defective of existing in prior technology, a kind of guiding bridge valve column plate to be provided.
The technical solution of the utility model is: a kind of guiding bridge valve column plate is characterized in that it is made up of guiding bridge valve and valve hole plate; Have bridge shape valve opening on the described valve hole plate; Described guiding bridge valve comprises bridge shape valve block, valve leg and flanging; Guiding bridge valve is installed in the bridge shape valve opening on the valve hole plate, and places bridge shape valve opening by the flanging floating ground.
The front-end and back-end of described bridge shape valve block and bridge shape valve opening are bar shaped, and the centre is arc or circle.
Described valve leg is made of the front and back leg, and preceding valve leg is greater than or equal to back valve leg.
The utility model has been drawn the advantage of circular float valve and rectangular valve, has developed more reasonably guiding bridge valve of structure.Be bar shaped before and after the bridge shape valve opening of guiding bridge valve column plate and the valve block, the centre is arc or circle, circular portion can effectively increase the girth of float valve, be issued to than the requirement of aspect in less length-width ratio in the hope of float valve than rectangular valve, increase float valve side gas passage,, make float valve arranging evenly in tower simultaneously because the float valve length-width ratio is less, the interior gas of tower is evenly distributed, can reduces entrainment effectively; Float valve can have two kinds of specifications, the valve leg is contour before and after a kind of float valve, the valve leg is not contour before and after the another kind of float valve, front valve leg height, back valve leg is low, and float valve is certain elevation angle in the operation, the elevation angle whereby, the gas that blows out from the float valve side has motive force forward, adds gas port blows out from the valve block a small amount of gas motive force to liquid, and the float valve of two kinds of specifications is suitably arranged and can be eliminated the gradient of liquid level in the tower and the liquid stagnation region at arc position; The valve block edge has triangle, waveform or profile of tooth groove, help refinement gas passage, reduce the contact point of float valve and valve hole plate simultaneously, float valve is contacted by line with the contacting pattern of valve hole plate become a contact, help the unlatching of float valve, have clear superiority for the formation of bubbling area on the column plate; The valve opening structure is middle wide, and front and back are narrow, can reduce the float valve column pitch effectively, increases the maximum percent opening of column plate, and this is of great benefit to the disposal ability that improves tower; Before and after the float valve is strip structure, is provided with bar shaped valve leg, and float valve does not rotate in operation, only can fluctuate reliable in structure.
The utility model adopts air-water-CO2 system, carried out the contrast experiment under the equal conditions with F1 type valve plate, guide float valve tray, the result shows, guiding bridge valve column plate described in the utility model, aspect hydrodynamics (entrainment rate, pressure drop and slip) and mass-transfer performance two, all have significantly and improve.
