Abstract
The invention relates to an S-shaped high efficiency oriented composite sieve tray. The tray is disposed in a plate tower layer by layer, and is composed of a central rectangular mass transfer area, arch mass transfer areas on the upper side and the lower side, as well as a liquid receiving area and a downflow area on the left side and the right side. As the effective mass transfer region of the tray is divided into the rectangular mass transfer area and the arch mass transfer areas, the effective mass transfer region is fully utilized, thus improving the processing capacity and the operating flexibility. The tray is operated under a spray state, thus preventing scaling blockage of the tray, greatly reducing the tray pressure drop, and being widely applicable to large liquid volume chemical separation operation.
Description
Technical field
The invention belongs to chemical separating apparatus field, relate to novel gas-liquid mass transfer apparatus in Chemical Engineering and make, relate in particular to the column plate of sieve aperture tower.
Background technology
Tower is mass-transfer progress equipment the most frequently used in industrial equipment; Conventional tower is pressed the textural classification of tower internals, mainly contains plate column and the large class of packed tower two.Because screen hole type plate column is simple in structure, easy to process, easily maintenance and cost are low, therefore more extensive in industrial application with respect to packed tower.But traditional sieve tray liquid stream in large liquid measure operating condition lower plate is inhomogeneous, and operating flexibility is little, and anode drop is large, easily fouling is stopped up, this column plate can only operate in very narrow scope, and when gas-liquid slightly fluctuates or inlet amount need improve, its plate efficiency declines.Therefore, the liquid that makes of development of new forms good flowing on column plate, strengthens gas-liquid mass transfer effect, reduces plate pressure drop; Prevent that the column plate that fouling is stopped up from seeming particularly important.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of operating flexibility large, anode drop is little, can prevent fouling obstruction simultaneously, greatly increase the effective district of mass transfer area, improve mass transfer effect, and the S type high-efficiency guide composite screen hole column plate of simple structure, easily manufactured, cheap, stable operation.
The concrete technical scheme of the present invention is: a kind of S type high-efficiency guide composite screen hole column plate, described column plate is successively arranged in board-like tower body, it is characterized in that described column plate consists of the rectangle mass-transfer zone at center, the upper and lower arc mass-transfer zone of both sides and the He Jiang liquid zone, liquid receiving area of the left and right sides, described rectangle mass-transfer zone is arranged side by side and is formed for the strip plate body of horizontal " S " type by cross section, between described adjacent plate body, interlaced and interval, " S " type end arranges, described interval forms air-flow passageway, and any one end of " S " type end of described every plate body offers air admission hole; Described liquid receiving area is the spill cell body forming with rectangle mass-transfer zone edge " S " template body; Described the tongue template that liquid zone comprises that the overflow plate that is vertically arranged at another edge of rectangle mass-transfer zone " S " template body, water conservancy diversion vertical plate and water conservancy diversion vertical plate end tilts arrange falls; Described arc mass-transfer zone comprises the plate body that plate body that two cross sections are L-type and cross section are " U " type, and the vertical plate of described L-type plate body is buckled in the notch of plate body of " U " type, and both form air-flow passageways in upper and lower space.
As preferably, the liquid receiving area that falls column plate under liquid zone correspondence of the upper column plate of adjacent upper and lower column plate.
As preferably, described in liquid zone falls and tongue template bottom and cell body bottom surface, liquid receiving area be close.
As preferably, adjacent upper and lower tray spacing is 300mm～600mm.
Its specific works principle is: the mass transfer between column plate mainly carries out at column plate upper space, and gas-liquid contact is water conservancy diversion spray regime, and liquid phase is discontinuous phase, and gas phase is continuous phase.Gas enters bottom, column plate top by rising on the air-flow passageway on column plate, liquid is fallen under liquid zone row by last layer, after tongue template current limliting is by liquid receiving area, overflow to column plate mass-transfer zone, by air admission hole and air-flow passageway, at rectangle mass-transfer zone and arc mass-transfer zone, there is fierce collision with the liquid from last layer in the mass-transfer zone gas phase at column plate, between plate, constantly form liquid film, and be broken into drop and mist, complete sufficient gas-liquid mass transfer contact, gas phase and drop between plate, acutely seethe and separated after, gas phase rises to last layer column plate, liquid phase is at gravity, under the force action of gas phase motive force and liquid receiving area liquid phase motive force, converge to and fall liquid zone, through water conservancy diversion tongue template, enter the liquid receiving area of lower one deck column plate.Whole Liquid Flow contact mass transfer process can be divided into holds liquid film forming, gas-liquid injection, rupture of membranes fragmentation and gas-liquid separation four-stage.Wherein hold liquid film forming and mainly occur in tower part surface, gas-liquid injection and rupture of membranes fragmentation mainly occur between tower part, and gas-liquid separation mainly occurs in tower part upper space.
Beneficial effect of the present invention: the effective mass-transfer zone of column plate is divided into rectangle mass-transfer zone and arc mass-transfer zone; Being fully used in the effective district of mass transfer, thereby has improved disposal ability and operating flexibility; Column plate operates under spray regime, and gas speed is higher, and the impurity such as particle, polymer, dirt are had to flushing self-purification capacity, has prevented column plate fouling blockage problem; The design of S template, makes gas phase pass through along air-flow passageway, and gas phase drag major part derives from liquid film, greatly reduce plate pressure drop, overcome the deficiency of conventional screen hole column plate, and device structure is simple, easily manufactured, operating flexibility is large, can be widely used in the chemical separating operation of large liquid measure.
