The specific embodiment
Further narrate the utility model below in conjunction with embodiment and accompanying drawing thereof:
The film spray no-back mixing column plate of the utility model design (is called for short column plate, referring to Fig. 1-4), level is installed in the tower shell 1, comprise jet cover, tower tray circle 2 and down-flow plate 3, have air rising hole on the column plate 5 and riser 11 is installed, constitute downspout 6 between down-flow plate 3 and the column plate 5, air rising hole corresponding position at column plate 5 is installing top cover 16 by gripper shoe 14, leave the space between the bottom of jet cover and the column plate 5, this space constitutes liquid and enters the interior passage of jet cover, two sidewalls of jet cover have spray-hole 13, it is characterized in that the air rising hole on the described column plate 5 is a rectangle, the air rising hole place is welded with rectangle riser 11, and riser 11 is up-narrow and down-wide, forms the nozzle-like gas passage; Described top cover 16, riser 11 are formed jet cover with gripper shoe 14; Between described two jet covers and the outside of edge jet cover intake chute 12 is installed, intake chute 12 3 faces have wall, an opening, openend stretches into downspout 6.
Jet cover described in the utility model (referring to Fig. 3,4) can be cuboid or prismatoid, is connected on the horizontal column plate 5 by gripper shoe 14 welding or bolt.Two sidewalls of jet cover are gripper shoe 14, and top cover 16 is installed in the upper end of gripper shoe 14, and the center position in the jet cover is installed riser 11.The top cover 16 of described jet cover can be surface plate, circular arc panel or V font panel (along long limit place's bending of top cover 16), the bending angle of V font panel top cover 16 is 90-150 °, and (embodiment is 120 °, referring to Fig. 5) obviously, the height of gripper shoe 14 has determined the mouth of pipe (being the gas phase nozzle) of riser 11 and the distance between the top cover 16.On two side panels of the rectangular jet cover between described top cover 16 and the riser 11, have spray-hole 13, spray-hole 13 sizes are calculated by hydrodynamics, the shape of spray-hole is then by different purposes decisions, can be the rectangular opening of a strip, also can open and be several uniform circular port or square opening.For example, the spray-hole 13 of embodiment is a circular port, aperture 15mm.
The described intake chute 12 of the utility model column plate is that three faces have wall, the dustpan-shaped structure of an opening, and its openend or opening simultaneously are liquid flowing outlet.This openend stretches in the downspout 6, can directly send into lower floor's column plate to the liquid that falls after rise by intake chute 12 and downspout 6.Intake chute 12 openends of embodiment stretch into 5-15cm in the downspout 6.Described intake chute 12 can be welded on the horizontal column plate 5 by four feets, also can be directly installed on two (sidewall) gripper shoes 14 between two adjacent jet covers.
The utility model column plate is owing to be equipped with riser 11 in injection (cap) cover, play the effect that reduces leakage on the one hand, on the other hand at riser 11 and rise between gas (plate) hole and can form fluid passage naturally, liquid can stream outside jet cover and enter in the jet cover, nozzle by the riser mouth upwards sprays, thereby can avoid the phenomenon that liquid is big because of pressure head or gas phase flow initiation liquid less than normal leaks down from air rising hole to a certain extent; The liquid that spray to rise is by the membrane fragmentation, and major part all falls in the described intake chute 12, avoided the back-mixing of liquid; By the height of adjustment downflow weir 10 and the height of nozzle, guarantee certain height of liquid layer on the nozzle simultaneously, made that the degree of crushing of liquid is better, improved mass transfer, heat transfer efficiency.
The operation principle and the process of the utility model column plate are, flow on the horizontal column plate 5 of this layer from downspout 6 by upper strata column plate dropping liq, enter in the jet cover from the jet cover side then, uprising gas enters from riser 11 liquid layer is held up, rise near the nozzle, make liquid membrane, fragmentation, ejection from the spray-hole 13 of jet cover both sides (gripper shoe), after the gas-liquid mixture of ejection drops on 12 li of intake chutes, flow out from openend, and flow to down on one deck column plate by downspout 6, gas then rises and enters the upper strata column plate.Highly constantly regulate when changing when tolerance and downflow weir 10, the flow size that enters liquid in the jet cover also can change thereupon.Because the liquid that comes out from jet cover directly enters intake chute 12 interior flowing, thereby has avoided the generation of liquid dispersion phenomenon, has improved mass transfer, the heat transfer efficiency of column plate, and has increased the column plate disposal ability.
The utility model column plate is by separating mass transfer and the not method of mass transfer liquid, change traditional liquid and return mobile path, avoided the back-mixing of liquid, gas-liquid mass transfer, the heat transfer efficiency of column plate have been improved, reduced the leakage that forms owing to gradient of liquid level, increased the operational stability of column plate, industrial operating flexibility can be designed to 40～150%.Can be widely used in technical process such as distillation in the chemical industry, desorb, absorption.
