Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is elaborated.Following examples are used for embodying the separating effect of three phase separator of the present invention, but do not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make certain adjustments and improvements.These all belong to protection scope of the present invention.
As shown in Figures 1 to 6, the present invention comprises entry conductor 1, lotion entrance 2, row hollow pipe 3, annulus guide plate 4, cylindrical tube 5, blade 6, annulus marker board 7, liquid bath 8, discharging tube 9, sand discharge pipe 11, mud scraper 12, dashpot 13, pump 14 for the three phase separator of sintering gas purifying;
Described entry conductor 1, it is tangentially connected with cylindrical tube 5; The shape of entry conductor can be equidistant or the cylindrical shell of involute-type or spiral spiral case cylindrical shell, as shown in Figure 2 A and 2B, and each several part variable dimension;
Described lotion entrance 2 is 5-30 ° of angle with main flume.Lotion is mainly surfactant solution.Addition is determined according to tar content in flue gas;
Described row's hollow pipe 3, row's hollow pipe 3 is positioned at the top of annulus guide plate 4; The shape of row's hollow pipe 3 can be cylindrical drum, as Fig. 3 A, can also be reducing pipe, as Fig. 3 B, and each variable dimension;
Described annulus guide plate 4, annulus guide plate 4 is positioned at cylindrical tube 5; The diameter of annulus guide plate 4, highly, ring distance, annulus number, opening size require to determine, as Fig. 4 according to three phase separation.Wherein one can be changed, binomial or multinomial;
Described cylindrical tube 5, its conventional material is RPP, stainless steel and composite, and each several part size requires to determine according to three phase separation.Cylinder inboard wall uses softwood matter, avoids particle and drop rebound and affect separative efficiency;
Described blade 6, blade 6 is positioned at the bottom of cylindrical tube 5, and paddle size is adjustable, and as Fig. 5, blade number requires relevant with placed angle to gas cleaning;
Described annulus marker board 7, annulus marker board 7 is positioned at the below of blade 6, and intermediate portion is divided into real plate 71, and be outwards the alternate annulus 72 of actual situation successively, as Fig. 6, space is the passage that liquid and particle enter liquid bath, and can stop the back-mixing of particle and liquid;
Described liquid bath 8, it is connected with cylindrical tube 5, and the particle entered in liquid bath 8 is separated with liquid, discharges respectively from discharging tube 9 and sand discharge pipe 11;
Described sand discharge pipe 11, its shape is bell mouth shape, and concrete size is determined according to quantity of sand and mud, notes avoiding arch formation;
Described mud scraper 12, it can be circulation scrapper conveyor or chain type mud scraper, and is positioned at the below of liquid bath 8, also can be other mud scrapers;

Sand discharge pipe 11 is provided with valve 10, controls the flow of sand discharge pipe for switch pair sand tube.
Mixed flue gas containing particle, drop and tar enters at a high speed from entry conductor, and after entry conductor, rotational gas flow under being formed between cylindrical tube and annulus guide plate, produces a downward main whirlpool.Meanwhile, there is lamination in flue gas between cylindrical tube and annulus guide plate, increases the tangential motion effective length of air-flow, reduces the generation of air flow shortcircuit.Drop and particle, under the effect of inertia, are separated along air-flow tangential direction, are fallen into liquid bath by the outlet space that gravity takes to bottom cylindrical tube.When main bumpy flow arrives cone base, through guiding lodicule, drop is separated with air-flow further with particle, improves purification efficiency.Main vortical flow changes axially-movable direction after arriving outlet, and form secondary whirlpool from bottom to top, secondary vortical flow, through annulus guide plate, reduces radial velocity, and then reduce further air-flow carrying secretly molecule and drop.When gas is discharged from row's hollow pipe, radiation shield prevents back-mixing turbulent flow phenomenon, further increases purification efficiency again.Fall into particle and liquid Separation of Solid and Liquid after sedimentation of liquid bath.Liquid exports to dashpot through discharging tube, at this, and the same aqueous phase separation of tar.Tar returns batch bin as sintering solvent, and aqueous phase squeezes into lotion entrance through pump, continues washing three phase separator inwall, recycles.The particle of precipitation is derived through sand discharge pipe by mud scraper.Through above-mentioned steps, gas, liquid, solid are thoroughly separated, and obtain clean flue gas, for the normal operation of follow-up various equipment provides strong guarantee.
Advantage of the present invention is as follows: one, have higher gas, liquid and solid separative efficiency; Two, structure simple, make simple and easy, to consume steel few, lightweight; Three, disposal ability is large, energy consumption is little.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change.
