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 fine and closely woven uniform and gas-to-liquid contact sufficient tongue type shunting float valve tray.
nullThe present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of tongue type 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 rectangle valve gap above column plate and the valve lower limb extended to downwards below column plate by the both sides of the edge that valve gap is relative，The tongue apertures that at least two that is provided with described valve gap upwards arches upward，The another both sides of the edge of described valve gap are 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 each sawtooth in this circle projection and the another both sides of the edge of valve gap，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 being provided with a shunting projection between each sawtooth on this circle projection and the another both sides of the edge of valve gap, 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 two openings tongue apertures in the same direction, and the opening of described tongue apertures is towards one of valve lower limb.
The improvement of technique scheme is: described valve gap, valve lower limb, tongue apertures and toothed edge are made as one.
