Abstract
The invention relates to a tongue type floating valve tower disc and belongs to the technical field of a common physical separation working device. The tongue type floating valve tower disc comprises a tower plate and a floating valve capable of moving up and down, wherein a mounting hole for mounting the floating valve is formed in the tower plate; the floating valve comprises a rectangular valve cover arranged above the tower plate and valve legs which extend downward from the two opposite edges of the valve cover to the lower side of the tower plate; at least two upward arched tongue holes are formed in the valve cover; the other two side edges of the valve cover are provided with downwards-folded saw tooth edges; the saw tooth edges of the valve cover are used for being abutted against the upper surface of the tower plate when the floating valve falls down; one circle of bulge is fixed on the bottom surface of the valve cover; the tongue holes are located in the circle of the bulge of the valve cover; a cavity with a clamping space is formed in the valve cover; and the cavity is internally filled with a polystyrene foam layer. The tongue type floating valve tower disc has the advantages of fine, dense and uniform airflow dispersion and sufficient gas-liquid contact.
Description
Technical field
The present invention relates to a kind of tower tray, belong to general physical separation apparatus for work technical field.
Background technology
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 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 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.
At present, although valve plate has had larger improvement in operating flexibility, aborning, applicant finds, in industrial production, air-flow rises irregular, and cause the process of float valve to air-flow undesirable, air dispersion is uneven and gas-liquid contact is insufficient.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of air dispersion fine and closely woven evenly and gas-liquid contact sufficient tongue type float valve tray.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of tongue type 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 to be located at rectangle valve gap above the column plate both sides of the edge relative with by valve gap and to extend to valve leg below column plate downwards, described valve gap is provided with at least two tongue apertures upwards arched upward, the another both sides of the edge of described valve gap are 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, described valve gap bottom surface is fixed with a circle protruding, described tongue apertures is positioned at this circle projection of described valve gap, be shaped with in described valve gap folder every cavity, layer of polystyrene foam is filled with 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, tongue apertures is positioned at this circle projection of valve gap, air-flow erratic directly to blowing up time, force to compare uniform shunting to air-flow, flow out from the toothed edge of tongue apertures and 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 reduce entrainment, improve 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, and reduce gas directly to blowing up, effectively reduce mist entrainment, zigzag structure strengthens vehicle repair major level of disruption, promotes that mass transfer surfaces is constantly updated, improves mass-transfer efficiency.
The improvement of technique scheme is: described toothed edge is downwards in the flanging of 5 ° ~ 15 °.
The improvement of technique scheme is: described valve gap is provided with two openings tongue apertures in the same way, and the opening of described tongue apertures is towards one of valve leg.
The improvement of technique scheme is: described valve gap, valve leg, tongue apertures and toothed edge are made as one.
