Abstract
The invention relates to a round flow dividing floating valve tower disc and belongs to the technical field of a common physical separation working device. The round flow dividing 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 round valve cover arranged above the tower plate and valve legs which extend downward along the peripheral direction of the valve cover to the lower side of the tower plate; the valve legs are distributed at intervals along the peripheral edge of the valve cover; at least two upward arched tongue holes are formed in the valve cover; the peripheral edge of the valve cover is provided with a downwards-folded saw tooth edge; the saw tooth edge of the valve cover is 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; one flow dividing bulge is arranged between the circle of bulge and each saw tooth at the peripheral edge 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 round flow dividing 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 simple in construction, manufacturing expense is cheap, and adapts to the material situation commonly used, and 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 the Yield and quality of product, the response rate, the various aspects such as economic benefit.
The feature of valve tower is one float valve moving up and down of installation at each installing hole.When installing hole high cycle speed, float valve is risen by jack-up, and when air speed is low, float valve is because declining from heavy sensation of the body.Float valve lifting position is automatically adjusted with throughput size, so that the gas speed entering liquid layer is basicly stable.Enter liquid layer because of gas in float valve lower horizontal direction again, both reduced liquid foam entrainment amount, and extended again gas-liquid contact time.The valve block of float valve regulates its open degree along with the change of gas load, and therefore, the operating flexibility of valve tower is big, particularly when underload, remains to keep normal operating.
Valve tower is in good condition due to gas-to-liquid contact, mist entrainment little (because of gas level blowout therefore), plate efficiency is higher, and production capacity is bigger.
At present, although valve plate has had bigger improvement in operating flexibility, but aborning, it has been found that in commercial production, air-flow rises irregular, causes float valve undesirable to the process of air-flow, air-flow dispersion is uneven and gas-to-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-flow and disperses the fine and closely woven uniform and sufficient round shunting float valve tray of gas-to-liquid contact.
nullThe present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of round shunting float valve tray，Including column plate and float valve moving up and down，The installing hole installed for float valve it is shaped with on described column plate，Described float valve includes being located at the circular valve gap above column plate and being extended to downwards the valve lower limb below column plate by valve gap periphery，Described valve lower limb is spaced apart along valve gap periphery，The tongue apertures that at least two that is provided with described valve gap upwards arches upward，The periphery of described valve gap is provided with the toothed edge being turned over downwards，The toothed edge of described valve gap for abutting described column plate upper surface when float valve falls，A circle it is fixed with protruding on described valve gap bottom surface，Described tongue apertures is positioned at this circle projection of described valve gap，A shunting projection it is provided with between this circle projection and each sawtooth of valve gap periphery，Be shaped with in described valve gap press from both sides every cavity，It is filled with layer of polystyrene foam in described cavity.
The present invention uses technique scheme to provide the benefit that: 1) protruding by being fixed with a circle on valve gap bottom surface, tongue apertures is positioned at this circle projection of valve gap, air-flow is erratic blow directly up time, force air-flow compares uniform shunting, flow out at the toothed edge of tongue apertures and valve gap, make air-flow dispersion the finest and closely woven uniformly, gas-to-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 press from both sides every cavity, layer of polystyrene foam it is filled with in cavity, make valve gap lighter in weight and for damping valve gap, the amplitude of valve gap vibration when air-flow is erratic to be blown directly up can be reduced, keep the position of toothed edge and being relatively fixed of angle of valve gap, disperse through sawtooth so that stitch the air-flow ejected from valve, make gas-liquid have bigger attaching space；3) sawtooth has to lower hem, reduces gas and blows directly up, effectively reduces 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) by the shunting projection being provided with between this circle projection and each sawtooth of valve gap periphery, air-flow can be shunted more uniformly.
The improvement of technique scheme is: described toothed edge is downwards in 5 °～the flanging of 15 °.
The improvement of technique scheme is: described valve gap is provided with five and upwards arches upward and tongue apertures that opening direction is identical.
The improvement of technique scheme is: the opening direction of described tongue apertures is towards between adjacent two valve lower limbs.
The improvement of technique scheme is: described valve gap, valve lower limb, tongue apertures and toothed edge are made as one.
