Abstract
The invention relates to a disc-shaped float valve tower disc. The tower disc comprises a tower plate and a float valve which can move up and down, wherein 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 polystyrene foam layer is arranged in the valve cover. The disc-shaped float valve tower disc has the advantages that airflow dispersion is fine, dense and uniform, and gas-liquid contact is full.
Description
Technical field
The present invention relates to a kind of tower tray, belongs to general physical separation apparatus for work technical field.
Background technology
Circular float valve tower（It is called disc valve tower）It is a kind of new tower, simple structure, manufacturing expense is cheap, and can fit
The material situation that should be commonly used, is one of widest tower used in chemical industry, oil refining industry.Tower equipment in valve tower, its
The quality of performance, the height of technical merit directly affect the various aspects such as the Yield and quality of product, the response rate, economic benefit.
The characteristics of circular float valve tower is one float valve moving up and down of installation at each installing hole.When installing hole gas speed
Gao Shi, float valve is risen by jack-up, and when air speed is low, float valve from heavy sensation of the body because declining.Float valve lifting position is automatic with throughput size
Adjust, so that the gas speed into liquid layer is basicly stable.Again because gas enters liquid layer in float valve lower horizontal direction, liquid has both been reduced
Foam entrainment, extends gas-liquid contact time again.The valve block of float valve adjusts its open degree with the change of gas load, therefore,
The operating flexibility of circular float valve tower is big, particularly in underload, remains to keep normal operating.Valve tower is due to gas-to-liquid contact shape
State is good, mist entrainment it is little (because gas level blowout it is therefore), plate efficiency is higher, and production capacity is larger.
Although the tower tray of the floating tower of circle has biography effect matter rate high, the big advantage of operating flexibility, it has been found that in industry
In production, still have the disadvantages that：1）Because air-flow rising is irregular, cause process of the float valve to air-flow undesirable, air-flow
Dispersion is uneven and gas-to-liquid contact is insufficient；2）At column plate edge due to float valve can not be installed, mass transfer dead band is easily produced, make this
Region gas-to-liquid contact is not abundant enough.
The content of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose a kind of air-flow dispersion it is fine and closely woven uniform and
The uniform sufficiently Flexitray of gas-to-liquid contact, the tower tray is effectively reduced mist entrainment and improves mass-transfer efficiency.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of Flexitray, including column plate
With float valve moving up and down, the installing hole installed for float valve is formed with the column plate, the float valve is included on column plate
The circular valve gap of side and the valve lower limb below column plate is extended to downwards by valve gap periphery, the valve lower limb is along valve gap periphery interval point
Cloth, the periphery of the valve gap is provided with the toothed edge being turned over downwards, and the toothed edge of the valve gap is used to abut institute when float valve falls
Column plate upper surface is stated, some tongue apertures are offered on the column plate；A circle is fixed with the valve gap bottom surface raised, in the valve gap
Be formed with press from both sides every cavity, layer of polystyrene foam is filled with the cavity.
The present invention is using the beneficial effect of above-mentioned technical proposal：1）It is raised by being fixed with a circle on valve gap bottom surface,
Air-flow is erratic when blowing directly up, and pressure is compared uniform shunting to air-flow, flows out from the toothed edge of valve gap, makes
Flow point of bringing about the desired sensation dissipates finer and closely woven uniform, and gas-to-liquid contact is more abundant, reduces the gas speed of valve periphery ejection, also reduces between valve
Air-flow liquidates, and so as to reduce entrainment, improves plate efficiency and production capacity；2）By be formed with valve gap press from both sides every sky
Chamber, layer of polystyrene foam is filled with cavity so that valve gap lighter in weight and to damp valve gap, it is possible to reduce air-flow is irregular
Valve gap when blowing directly up vibration amplitude, keep valve gap the position of toothed edge and being relatively fixed for angle so that
From the air-flow jagsaw tooth dispersion that valve seam is ejected, gas-liquid is set to have bigger attaching space；3）Sawtooth has to lower hem, reduces
Gas blows directly up, is effectively reduced mist entrainment, and zigzag structure strengthens vehicle repair major level of disruption, promotes mass transfer
Surface is constantly updated, and improves mass-transfer efficiency；4）Tongue apertures is opened up on column plate, the liquid on column plate can be accelerated to flow, reduce liquid
Back-mixing；Meanwhile, the tongue apertures expands open ratio of plate, reduces, and extends the time of staying of the liquid on column plate, strengthens
The exchange of the liquid on liquid flow direction and mixed, eliminates the stagnant wake of column plate both sides, reduces foam layer height,
So as to be effectively improved the efficiency and production capacity of tower tray.
The improvement of above-mentioned technical proposal is：The distribution density of the tongue apertures at the column plate edge is more than the column plate zone line
Tongue apertures distribution density, can so promote the Flow of Goods and Materials at column plate edge, reduce edge mass transfer dead band.
The improvement of above-mentioned technical proposal is：The toothed edge is downwards in 5 °～15 ° of flanging.
