Description
Technical field
The invention belongs to chemical separating apparatus field, relate to novel gas-liquid mass transfer apparatus in Chemical Engineering and make, particularly relate to the column plate of sieve aperture tower.
Background technology
Tower is mass-transfer progress equipment the most frequently used in industrial equipment; The textural classification of tower internals pressed by conventional tower, mainly contains plate column and the large class of packed tower two.Because screen hole type plate column structure is simple, easy to process, easily maintenance and cost is low, therefore industrially applies more extensive relative to packed tower.But traditional sieve tray liquid stream in large liquid measure operating condition lower plate is uneven, and operating flexibility is little, and anode drop is large, easy fouling and clogging, this column plate can only at very narrow range of operation, and when gas-liquid slightly fluctuates or inlet amount need improve, namely 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 the column plate of fouling and clogging from seeming particularly important.Current in the rectifying column of waste water deaminizing, in the majority with plate column.Traditional sieve tray is to poor for adaptive capacity during waste water deaminizing, and liquid stream is uneven onboard for main manifestations, and easy fouling and clogging circulation passage causes resistance excessive; And this column plate is comparatively responsive to the fluctuation of load, when gas-liquid slightly fluctuates or inlet amount need improve, its plate efficiency declines obviously; When basicity in waste water is higher or organic concentration is higher, the foam in distillation process can choked flow circulation passage.And the runner that existing S type high-efficiency guide meets in sieve tray is arranged because of S type, can only one-sidedly flow, limited efficacy.Therefore, strive high-concentration ammonia nitrogenous wastewater, need development of new rectifiying plate, make liquid on column plate, form good flowing, strengthen gas-liquid mass transfer effect, reduce column plate resistance further; Alleviate and even prevent fouling and clogging column plate.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, there is provided the good anti-fluctuation ability of a kind of load adaptability strong, effectively can prevent fouling and clogging column plate, prevent froth buildup runner, increase mass transfer effective coverage area, improve mass transfer effect, and the U-shaped column plate of waste water deaminizing stripping rectifying of simple structure, easily manufactured, cheap, stable operation.
For realizing the object of the invention, provide following technical scheme: the U-shaped column plate of a kind of waste water deaminizing stripping rectifying, described column plate is successively arranged in board-like tower body, it is characterized in that the rectangle mass-transfer zone of described column plate by center, the crescent mass-transfer zone of upper and lower both sides and the liquid receiving area of the left and right sides and fall liquid zone and form, the strip plate body laid out in parallel that described rectangle mass-transfer zone is laterally " U " type by cross section forms, between described adjacent plate body, interlaced and interval, " U " type end is arranged, described interval forms air-flow passageway, the two ends of " U " type end of described every block plate body all offer air admission hole, air admission hole aperture φ 3-6mm, pitch-row 8-22mm, described liquid receiving area is the spill cell body formed with rectangle mass-transfer zone edge " U " template body, the described liquid zone that falls comprises the water conservancy diversion vertical plate and defoaming plate that are vertically arranged at another edge of rectangle mass-transfer zone " U " template body, the plate body of to be L-type margin plate and one piece of cross section be " U " type that described crescent mass-transfer zone comprises two pieces of cross sections, the vertical plate of described L-type margin plate is buckled in the notch of the plate body of " U " type, both upper and lower spaced formation air-flow passageways.
As preferably, the liquid receiving area falling column plate under liquid zone correspondence of the upper column plate of adjacent upper and lower column plate.
As preferably, described in the defoaming plate of liquid zone falls and cell body bottom surface, liquid receiving area is close.
As preferably, adjacent upper and lower tray spacing is 250mm ~ 650mm.
Beneficial effect of the present invention: the effective mass-transfer zone of column plate is divided into rectangle mass-transfer zone and crescent mass-transfer zone; In rectangle mass-transfer zone, column plate adopts U-shaped structure, more U-shaped structure both sides all have pore, makes U-shaped structure both sides all can abundant mass transfer, and being fully used in the effective district of mass transfer, thus improves disposal ability and operating flexibility; Column plate operates in the state of a spray, and gas speed is higher, has flushing self-purification capacity, prevent column plate fouling and clogging problem to impurity such as particle, polymer, dirts; The design of U-shaped plate, gas phase is passed 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.
