Description
Technical field
The utility model relates to a kind of gas-liquid contanct equipment that is used for Chemical Manufacture, particularly a kind of Orientating Injection Column Tray.
Background technology
Jet tray is to have air rising hole on a kind of plate, and jet cover is arranged on the air rising hole, between jet cover and the tower tray certain interval is arranged, and jet cover is provided with the plate column in Guide spray hole.In operating process, liquid flows into air rising hole from the gap under the jet cover, the air-flow that is risen pulls into liquid film then, be broken into very little drop by the aperture on the sidewall again, between the gas-liquid in cover by after the violent collision mixing, eject in covering by the spray-hole on the jet cover again, outside the cover spray back gas-liquid separation is come mutually, liquid flows to down one deck tower tray by downspout, gas enters the last layer tower tray by the air rising hole of last layer tower tray, thereby reaches the purpose of gas-liquid mass transfer and heat transfer.
Jet tray has multiple pattern: patent ZL92236034.0 and has invented the jet tray that a kind of cover body is rolled into expanded metals, and many rhombus ducts are arranged on the cover body.Patent ZL93218445.6 has invented a kind of trapezoidal solids and has sprayed gas-liquid cntacting combined components, this composition element is that the curved surface cover plate that separating plate or top have spray-hole is installed on the trapezoidal jet cover of bottom and open-top, on the sidewall of the four sides of jet cover, have spray-hole, have imbibing hole on the end plate and push away the liquid hole.Patent CN1181282A has invented a kind of mixing box column plate, have a plurality of sieve apertures on the column plate, 2-10 sieve aperture is listed as into one group of hole bunch, every group of top is covered with the blending bin of the no end, mix the casing top seal, one side has the gas outlet, and direction is consistent with liquid flow path direction on the plate, and the upper and lower of gas outlet respectively has a deflector.Patent CN1204543A has invented a kind of full effective region cross flow tower plate, with jet tray or vertical sieve tray on the downcomer region cloth.Patent ZL99200122.6 has invented a kind of radial side guiding jet column tray, guide plate being installed to prevent the back-mixing of liquid around the jet cover and on the top cover, reduces the column plate resistance.Patent ZL01221920.7 has invented a kind of Guide spray column plate, the Guide spray separating plate has been installed to reduce backmixing of liquid phase and entrainment above jet cover.Patent ZL01221921.5 has invented a kind of combined trapezoid spray tray, and the separating plate that three-layer stereo is arranged has been installed above jet cover, to reduce mist entrainment, improves the separative efficiency of column plate.Patent ZL01224885.1 has invented a kind of nozzle baffle type tower tray, two separating plates is installed to reduce mist entrainment below air rising hole.
Above-mentioned various jet tray all has the characteristics that treating capacity is big, separative efficiency is high, but also all exists the shortcoming that operating flexibility is little, plate pressure drop is big, leaking liquid amount is big.The design of plate column at first will make gas-liquid fully contact, and will reduce mist entrainment and backmixing of liquid phase amount then, could improve plate efficiency.But also to reduce gas holdup in the liquid phase, and guarantee that liquids and gases have enough circulation passages, reduce the chance of liquid flooding, the chance that the minimizing liquid that will try one's best is simultaneously revealed improves the operating flexibility of tower.
Summary of the invention
The purpose of this utility model is to improve the deficiency of existing jet tray, designs the new tower plate that a kind of efficient is higher, operating flexibility is bigger, plate pressure drop is littler.The utility model is realized above-mentioned purpose by taking following measure:
Orientating Injection Column Tray of the present invention, each air rising hole on the tower tray is provided with jet cover; Jet cover is provided with the Guide spray hole.
Guide spray hole on the described jet cover top cover is strip hole or circular port.
Between jet cover and tower tray, be connected by bracing frame, gapped between jet cover and the tower tray.
Described air rising hole can be circle, rectangle, square or polygon; The edge of air rising hole is the duct that has the convergent cross section, on the edge of air rising hole the weir is arranged.
Described jet cover is and the corresponding cylinder of air rising hole, cone, cube, prismatoid or polyhedron.
The both sides of described jet cover or both sides and front side or have spray-hole all around.
The structure of concrete jet tray and using as Fig. 1, Fig. 2 and shown in Figure 3: cylindrical-shaped tower interior 1 is provided with several layers tower tray 9; Each tower tray is provided with several air rising holes 11; All be provided with one or more overflow pipes 10 on each tower tray, and under operating condition, make the liquid layer that to keep certain height on the tower tray; On each corresponding air rising hole a Guide spray cover 5 is arranged, jet cover is made up of cover tube, top cover 3 and support 12; Jet cover is fixed on the column plate by several bracing frames 12; Jet cover is provided with Guide spray hole 2 and spray-hole 4; Certain clearance 8 is arranged between Guide spray cover and the tower tray.
Air rising hole can be circle, rectangle, square or polygon; The edge of air rising hole can be vertical duct or the duct 7 that has the convergent cross section, and the duct that preferably has the convergent cross section reduces plate pressure drop to reduce the resistance of uprising gas by tower tray; Thereby there is weir 6 to reduce back-mixing between the plate of liquid with the liquid amount of leakage that reduces tower tray on the edge of air rising hole, improves separative efficiency, increase operating flexibility.
Guide spray cover 5 can be and the corresponding cylinder of air rising hole, cone, cube, prismatoid or polyhedron, preferably up big and down small inverted cone or inverted ladder-shaped body, so that flow to oblique below from the gas-liquid mixture of spray-hole ejection, increase the path that gas passed through, make the fluid of ejection have downwards component velocity, thereby reach the effect that reduces mist entrainment; The top of Guide spray cover is provided with the Guide spray hole, and the direction of spray-hole is consistent with the liquid flow path direction, to reduce the resistance of gas by jet cover, reduces plate pressure drop and reduces gradient of liquid level on the column plate, reduces backmixing of liquid phase.
Compare with plate columns such as existing sieve-plate tower, bubble column, valve towers, because the mass-transfer progress of jet tray is to finish by the bubbling contact of gas in liquid unlike above-mentioned plate column, but liquid is pulled into very thin liquid film by gas, and then be broken into very little drop, finish by collision, mixing, separation again between gas and the drop.Jet tray has increased the surface area of gas-liquid contact significantly, has utilized the solid space in the tower fully, has improved the separative efficiency of tower tray; Help the abundant contact of gas-liquid simultaneously owing to the increase of tolerance in the jet tray, so the disposal ability of jet tray is bigger; Owing to the gas injection direction and the tower tray radial parallel of jet tray, changed the movement locus of the droplet of carrying secretly in the gas, and reduced mist entrainment again; Also, also reduced the gas holdup in the liquid layer significantly, and made jet tray be difficult for taking place the liquid flooding phenomenon owing to do not have the bubbling phenomenon in the liquid layer on the plate of jet tray.
After taking above-mentioned measure, the utility model is compared with existing jet tray: 1, plate pressure drop has reduced 10-20%; 2, the leak of liquid amount has reduced 50-100%; 3, mist entrainment has reduced 20-100%; 4, plate efficiency has improved 10-60%; 5, operating flexibility has improved 100-200%; 6, be easy to processing and manufacturing.
