Description
Technical field
The utility model belongs to the separator technical field in the chemical industry extraction process, relates to a kind of liquid-liquid extraction apparatus, specially refers to a kind of pulse extraction device of a device two tower structures.
Background technology
At present the mechanical agitation extraction tower that uses has pulsed, rotating disc type and vibratory sieve board-like, wherein the pulsed extraction tower with simple in structure, volume is little, in the tower no drive disk assembly advantage and be widely used.And be confirmed in the scale of laboratory experiment, but in commercial Application, under the situation for big tower diameter, impulse generator is difficult to produce industrial production and requires even, stable pulse, has limited the disposal ability of pulsed extraction tower.
Summary of the invention
The purpose of this utility model provides a kind of pulse extraction device of a device two tower structures, and the liquid-needed pulse strength of liquid extract and separate of industrial high throughput can be provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pulse extraction device of a device two tower structures comprises an impulse generator and two identical sieve-plate towers; Each extraction tower all is made up of light phase settling section, tower body and heavy phase settling section; The heavy liquid inlet and has liquid distribution trough above tower body; Light phase liquid inlet is on heavy phase settling section top; Arch sieve plate, baffle plate, support have constituted the redistributor of pulse liquid; Impulse generator is the horizontal bar piston type, moves back and forth double acting on two sieve-plate towers; The medium of the inboard lining of cylinder body smooth abrasion-proof; The hermetic unit of piston is corrosion resistant leather cup formula two way seal ring; Piston rod links to each other with motor, and has axial seal.
When liquid upwards rushes in the tower, through the buffering of baffle plate, around baffle plate, move upward, be evenly distributed in the tower by the arch sieve plate again.
Impulse generator both sides liquid property is identical, and two tower structures are the same, and is approaching equal at the fluid pressure of piston both sides, reduced the requirement to sealing, and piston ring packing is effective, long service life.
Effect of the present utility model and benefit are: the pulse extraction device of a device two tower structures has simple in structure, flexible operation, applied widely, pulse stabilization, and the advantage that pulsatile effect is good can satisfy the big requirement of industrial treating capacity.

The specific embodiment
Be described in detail the specific embodiment of the present utility model below in conjunction with technical scheme and accompanying drawing.
With pump continuous phase 11 is transported in the tower by gently entering the mouth mutually, guarantees that the continuous phase liquid level in the tower just there be not heavy phase liquid distribution trough 7 get final product, all there is liquid the impulse generator both sides at this moment; With pump decentralized photo is carried in tower by heavy liquid inlet 6 then; Wherein decentralized photo (heavy phase) is an extractant; Heavy liquid inlet 6, the light 11 interior flow rate of liquid that enter the mouth mutually have flowmeter survey, and the size that changes flow is adjusted the extraction ratio; Heavy phase promptly is distributed in the continuous phase with the form of droplet after by liquid distribution trough 7, two liquid phases can be started impulse generator after carrying liquid simultaneously in tower, piston 16 moves back and forth about under the drive of motor and forces that liquid forms pulse up and down in the tower, by regulating motor, change piston reciprocating stroke and frequency in cylinder, reach the purpose (pulse strength is the product of pulse amplitude and frequency) of pulse strength in the control tower; Liquid formation eddy current, two-phase liquid level layer steadily do not form local emulsion layer in ambassador's extraction tower for fear of crossing owing to pulse strength, the pulse liquid distributor is installed in tower body 4 bottoms, liquid distribution trough comprises arch sieve plate 10, baffle plate 11 and supports 12, wherein the aperture of arch sieve plate 10 is 20mm, percent opening is 30%～40%, when liquid upwards rushes in the tower, buffering through baffle plate, around baffle plate, move upward, be evenly distributed in the tower by the arch sieve plate again, be lined with the lubricious of wear resistant corrosion resistant in impulse generator inside.
By changing pipeline and the valve between tower, can carry out the series and parallel operation of double tower.All there is liquid the piston both sides of impulse generator, and liquid property is identical, and the piston pressure at both sides is near equating that liquid level is identical in the tower, and the sealing effectiveness of piston ring is better.
Use the pulse extraction device of a device two tower structures in the utility model to handle certain factory's waste water, tower height 20m, tower diameter 2m, pulse tube diameter 700mm, organic mass fraction is reduced to below 0.5% in the waste water, about 100-200 tons/days of wastewater treatment capacity.
