Abstract

A combined tower tray is composed of tower plate with regularly arranged gas-raising holes, spray unit on said tower plate, liquid collector, down-flow spout and secondary down-flow spout. Said spray unit has a spray cover above said tower plate and with spray holes, and two-layer gas-liquid separating unit above said spray cover and consisting of a perforated plate and a blind plate.

Description

Compound injection tray
Technical field
The present invention relates to a kind of Compound injection tray, belong to the tower inner parts structure technology that operating process such as chemical industry rectifying, absorption, desorb are used for mass transfer, heat transfer.
Background technology
The existing jet tray that is used for rectifying column, absorption tower, desorber, its structure comprise by column plate, injection unit and formed by liquid bath, downspout and secondary downspout on the column plate.Described injection unit is: the vectored injection hole of offering on column plate as solid tongue column plate, or is provided with injection component, as New Vertical Sieve Tray on column plate.Though these column plates have the big advantage of operating flexibility, be difficult to adapt to the bigger operating condition of gas-liquid load in the tower, therefore develop a kind of jet tray that is suitable for big gas-liquid load in the tower, have realistic meaning and certain economic benefits widely.
Summary of the invention
The object of the present invention is to provide a kind of Compound injection tray, this tower tray is particularly suitable for the operation of big gas-liquid load in the tower, and operating flexibility is big, the plate efficiency height.
The present invention is realized by following technical proposals, a kind of Compound injection tray, this tower tray comprises by column plate, injection unit on the column plate, be subjected to liquid bath, downspout and secondary downspout are formed, it is characterized in that, described injection unit structure, be on column plate, to have regularly arranged air rising hole, jet cover is installed on air rising hole, leave the slit between jet cover and the column plate, have spray-hole on the jet cover, the gas-liquid separation plate of two-layer level board is installed in the top of jet cover, wherein has air rising hole on lower floor's gas-liquid separation plate, gas-liquid separation plate in upper strata is a blind plate, leaves the slit between the two-layer gas-liquid separation plate; Close downspout one side at column plate is provided with at least one secondary downspout.
Having regularly arranged air rising hole on the above-mentioned column plate is rectangular opening or trapezoidal hole.
Above-mentioned jet cover and the slit between the column plate are: 0~20mm.
The air rising hole of offering on lower floor's separating plate of above-mentioned gas-liquid separation plate is circular hole, rectangular opening, trapezoidal hole, tri-angle-holed, semicircle orifice, elliptical aperture or their combination.
Leaving clearance distance between the above-mentioned two-layer gas-liquid separation plate is 0~30mm.
The above-mentioned secondary downspout that is provided with is circle, rectangle, trapezoidal or semicircle.
The present invention has following advantage, is suitable for the operation of big gas-liquid load in the tower, and operating flexibility is big, when the void tower kinetic energy factor reaches 3.7Pa 0.5, liquid residence time reaches 2.5s in the downspout, and overflow intensity reaches 150m 3/ (mh) time, column plate still can be efficiently, stable operation, operation abnormalities such as liquid flooding, excessive entrainment can not occur.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view after Fig. 1 removes downspout.
Among the figure: 1 is secondary downspout, and 2 is jet cover, and 3 is the spray-hole on the jet cover, 4 are following gas-liquid separating plate, 5 is connector, and 6 is last gas-liquid separation flat board, and 7 is downspout, 8 is tower body, 9 is injection channel, and 10 is passage between jet cover and the column plate, and 11 are the air rising hole on the following separating plate, 12 is the column plate air rising hole, and 13 is column plate.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is done further auspicious stating:
The operation principle of composite injection column plate is: liquid flows down from the overflow mechanism and the secondary downspout of last layer column plate, gas enters in the jet cover by air rising hole from the below of column plate, when in gas enters jet cover, rising, liquid by jet cover at the bottom of the crack enter in the jet cover, and blown by gas and to pull into very thin liquid film, liquid film is broken into drop under capillary effect in by the process of gas lift.This burst gas-liquid mixed stream is by spray-hole and injection channel ejection.Gas-liquid mixed stream part by the top ejection is injected on following one deck gas-liquid separation plate, and remaining can be ejected on top one deck gas-liquid separation plate by the air rising hole on following one deck gas-liquid separation plate.After the cohesion, fall back to tray surfaces under the effect of gravity on the drop gas-liquid separation plate, gas is then walked around the separating plate group in the effect of pressure reduction, rises to the last layer column plate.Fall back to the liquid on the column plate, then flow to down one deck column plate by downspout and secondary downspout.
The present invention the experiment proved that: the additional overflow effect of secondary downspout has effectively improved the handling capacity of liquid, and effective gas-liquid separation effect of double-layer horizontal gas-liquid separation plate group effectively reduces entrainment.When the void tower kinetic energy factor reaches 3.7Pa 0.5, liquid residence time reaches 2.5s in the downspout, and overflow intensity reaches 150m 3/ (mh) time, overflow mechanism liquid flooding and obvious entrainment phenomenon do not appear.
