The invention discloses a disc-shaped flow-distributing float valve tower disc. The tower disc comprises a tower plate and a float valve, wherein the float valve can move up and down; a mounting hole used for mounting the float valve is formed in the tower plate; the float valve comprises a round valve cover and valve legs; the round valve cover is arranged above the tower plate; the valve legs downwards extend from the periphery of the valve cover to the place below the tower plate and are distributed along the periphery of the valve cover at intervals; a sawtooth edge which is downwards turned and folded is arranged on the periphery of the valve cover and pushes against the upper surface of the tower plate when the float valve falls down; a plurality of tongue holes are formed in the tower plate; a circle of bump is fixed to the bottom surface of the valve cover; a flow-distributing tooth is arranged between the circle of bump and each sawtooth on the periphery of the valve cover; a polystyrene foam layer is arranged in the valve cover. The disc-shaped flow-distributing float valve tower disc has the advantages that airflow dispersion is fine, dense and uniform, and gas-liquid contact is full.

Description

Disc shunting float valve tray
Technical field
The present invention relates to a kind of tower tray, belong to general physical separation apparatus for work technical field.
Background technology
Circular float valve tower (being again disc valve tower) is a kind of new tower, and structure is simple, and manufacturing expense is cheap, and can adapt to conventional material situation, is one of most popular tower in chemical industry, oil refining industry.Tower equipment in valve tower, the quality of its performance, the height of technical merit directly affect Yield and quality, the rate of recovery of product, the various aspects such as economic benefit.
The feature of circular float valve tower installs a float valve moving up and down at each installing hole place.When installing hole high cycle speed, float valve is risen by jack-up, and when air speed is low, float valve declines because self is heavy.Float valve lifting position regulates automatically with throughput size, thus makes the gas speed entering liquid layer basicly stable.Again because gas enters liquid layer in float valve lower horizontal direction, both reduce liquid foam entrainment amount, extended gas-liquid contact time again.The valve block of float valve regulates its open degree along with the change of gas load, therefore, the operating flexibility of circular float valve tower is large, particularly when underload, still can keep normal operating.Valve tower due to gas-liquid contact in good condition, mist entrainment little (because of gas level blowout therefore), plate efficiency is higher, and production capacity is larger.
Although it is high that the tower tray of circular floating tower has biography effect matter rate, the advantage that operating flexibility is large, applicant finds, in the industrial production, still there is following shortcoming: 1) because air-flow rises irregular, cause the process of float valve to air-flow undesirable, air dispersion is uneven and gas-liquid contact is insufficient; 2) at column plate edge due to can not float valve be installed, easily produce mass transfer dead band, make this region gas-liquid contact abundant not.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, and propose a kind of air dispersion fine and closely woven evenly and the gas-liquid contact evenly float valve tray of disc shunting fully, this tower tray can effectively reduce mist entrainment and improve mass-transfer efficiency.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of disc shunting float valve tray, comprise column plate and float valve moving up and down, described column plate is shaped with the installing hole installed for float valve, described float valve comprises the circular valve gap be located at above column plate and extends to the valve leg below column plate downwards by valve gap periphery, described valve leg is spaced apart along valve gap periphery, the periphery of described valve gap is provided with the toothed edge of turnover downwards, the toothed edge of described valve gap is used for abutting described column plate upper surface when float valve falls, and described column plate offers some tongue apertures; Described valve gap bottom surface is fixed with a circle protruding, is provided with one between the protruding and each sawtooth of valve gap periphery of this circle and shunt tooth, be shaped with in described valve gap press from both sides every cavity, be filled with layer of polystyrene foam in described cavity.
The present invention adopts the beneficial effect of technique scheme to be: 1) protruding by valve gap bottom surface being fixed with a circle, air-flow erratic directly to blowing up time, force to compare uniform shunting to air-flow, flow out from the toothed edge of valve gap, make air dispersion more evenly fine and closely woven, gas-liquid contact is more abundant, reduce the gas speed of valve periphery ejection, the air-flow also reduced between valve liquidates, thus reduces entrainment, improves plate efficiency and production capacity; 2) by be shaped with in valve gap folder every cavity, layer of polystyrene foam is filled with in cavity, make valve gap lighter in weight and for damping valve gap, the erratic amplitude directly to valve gap vibration during blowing up of air-flow can be reduced, keep the position of toothed edge and the relative fixing of angle of valve gap, thus make to stitch from valve the air-flow ejected and disperse through sawtooth, make gas-liquid have larger attaching space; 3) sawtooth has to lower hem, decreases gas directly to blowing up, effectively can reduce mist entrainment, and zigzag structure strengthens vehicle repair major level of disruption, promotes that mass transfer surfaces is constantly updated, improves mass-transfer efficiency; 4) shunt tooth, can shunt more uniformly air-flow for one by being provided with between this circle projection and each sawtooth of valve gap periphery; 5) on column plate, offer tongue apertures, the liquid flow on column plate can be accelerated, reduce liquid dispersion; Simultaneously, described tongue apertures expands open ratio of plate, reduce, extend the time of staying of liquid on column plate, strengthen perpendicular to the exchange of the liquid on liquid flow direction and mixed, eliminate the stagnant wake of column plate both sides, reduce foam layer height, thus effectively improve efficiency and the production capacity of tower tray.
The improvement of technique scheme is: the distribution density of the tongue apertures at described column plate edge is greater than the distribution density of the tongue apertures of described column plate zone line, can promote the Flow of Goods and Materials at column plate edge like this, reduces mass transfer dead band, edge.
The improvement of technique scheme is: described toothed edge is downwards in the flanging of 5 ° ~ 15 °.
