The specific embodiment

Fig. 1 is the schematic diagram of an example of continuous polymerization system 100.As shown in Figure 1, continuous polymerization system 100 comprises a series of parts, it is configured to polymerization and little by little produces more HMW (higher relative viscosity) polymer, polyamide for example, for example, as the aliphatic polyamide (, nylon) repeating to have between amide units at least 85% aliphatic key.Polyamide can be the polyamide of any appropriate, as nylon 6, nylon 7, nylon 11, nylon 12, nylon 6,6, nylon 6,9; Nylon 6,10, nylon 6,12, or their copolymer.

Continuous polymerization system 100 is configured to by making the aqueous solution of diamines-dicarboxylate prepare polyamide by continuous reaction zone continuously at super-atmospheric pressure.In acid amides formation temperature, from salt, for example supply with diamines-dicarboxylic acids salting liquid that storage 102 provides, by thering is at least one of reaction zone 104 (, reactor, flash vessel, finisher etc.) of one or more parts.The speed that salting liquid is advanced by each parts makes most salt be converted into polyamide.Polyamide reaction composition, in acid amides formation temperature and at the pressure that allows the formation of steam, passes through at least one other parts of reaction zone when still afterwards.In this other compartment, water is little by little removed from response composite as steam.Finally, composition comprises molten polyamide, and pressure is atmospheric pressure substantially, and the logistics of continuous polymerization is simultaneously left from reaction zone.As shown in Figure 1, continuous polymerization logistics being delivered to one or more streamline end components, comprising, for example, is fiber or be pellet by forming polymer fiber spinning machine or comminutor (being shown as parts 106) by polymer spinning respectively.

In an example, reaction zone 104 is before evaporimeter 108.The concentration (by removing of water) of the salting liquid providing from salt supply storage 102 is provided before polymerization evaporimeter 108 in reaction zone 104.

Be back to the discussion of the reaction zone 104 shown in Fig. 1, this reaction zone comprises reactor 110.Salting liquid is delivered to reactor 110, and the condition in reactor (for example, temperature and pressure) is remained to the formation that the salt of major part is converted into polymer and prevents steam.As further illustrated in Fig. 1, flash vessel 112 is arranged on reactor 110 downstreams.In flash vessel 112, in the situation that pressure gradually reduces to keep amidatioon temperature.Pressure reduce to allow water as steam and reactive material (for example, water and polymer) separated.The finisher 114 that the mixed flow of polymer and steam is fed to continuously to heating, wherein completes polymerization to required degree.The degree of polymerization uses the polymer viscosity usually used as relative viscosity or RV measurement indirectly to represent.In aftercondensated step, control viscosity.In the temperature raising, the degree of polymerization is the function of the amount of existing water, and by its restriction.Therefore,, along with water is removed as steam from polymer fluid by finisher 114, RV increases (for example, polymer degree increases).

Need RV than passing through at the much higher polyamide of the obtainable RV of steam balance for atmospheric pressure.High RV polymer for example, by preparing the compounding substances of polymer and water in finisher 114 (, finisher assembly) with the steam that reduces dividing potential drop.In aftercondensated or by using inert atmosphere or the steam that reduces dividing potential drop being provided by the aftercondensated under partial vacuum (providing with vent condenser in an example).Aftercondensated can be in the interior significant time of staying of finisher 114.The problem that aftercondensated has is, for the time that produces the required increase of high-viscosity polymer by the steam load compounding substances of polymer and water in finisher 114 can cause gelation or deteriorated polymer otherwise.For example, gel forms along one or more parts of finisher 114, or by forming along splashing of chamber wall, and along with gel is removed from finisher, it can stop up the quality of outlet opening or the deteriorated output polymer of finisher.

As further shown in Figure 2, finisher assembly 200 comprises the heat exchanger jacket 227 around finisher container 204 location.In an example, heat exchanger jacket 227 operations are with heated polymerizable logistics body, and for example, the polymer fluid that melt pool 224 contains, to promote water with form the removing by vent condenser 226 of steam.In an example, the size and dimension that regulates heat exchanger jacket 227 adds hot fluid flowing therein to receive.In an example, add hot fluid and include but not limited to, the solution of the biphenyl-diphenyl ether providing in the heat exchanger jacket 227 adjacent with finisher container 204 as steam.As further shown in Figure 2, finisher assembly 200 comprises cylinder 213 (for example, the cylinders at outlet opening 208 places).Cylinder 213 and the polymer fluid sent by it are optionally heated by heat exchanger jacket 227.In an example, the heat exchanger jacket 227 being connected with cylinder 213 is the independent chucks that are configured to provide the liquid stream that heats fluid therein.The liquid that adds hot fluid includes, but not limited to the biphenyl-diphenyl ether of liquid form.

Referring again to Fig. 2, finisher assembly 200 comprises the outlet opening 208 of the opening part of cylinder 213.Adjust the size and dimension of oral pore 208 to pass through its delivery polymer fluid, for example, to one or more streamline end components 106, as shown in Figure 1 fiber spinning machine or comminutor.In an example, outlet opening 208 and cylinder 213 comprise the screw pump 210 with screw rod 212 therein.The screw rod 212 of rotary screw pump 210 is to be delivered to one or more streamline end components 106 from finisher container 204 in the mode of measuring by polymer fluid.In another example, downstream pump is inserted between finisher assembly 200 and streamline end component 106 as positive displacement gear pump.Downstream pump by the polymer fluid of sending from finisher assembly 200 be pumped to these parts 106 to one or more.

Referring again to Fig. 2, in an example, finisher assembly 200 comprises agitator 214.As shown, agitator 214 is connected with the screw rod 212 of screw pump 210.Therefore, the rotation of screw rod 212 is passed to agitator 214 to stir the polymer fluid 228 in (mixing as described herein, and wiping) melt pool 224.The stirring being provided by agitator 214 mixes the polymer in melt pool 224 consistently, heat distributed from heat exchanger jacket 227, and the generation of delayed gel in melt pool 224.Shown in this example, agitator 214 comprises from the hurricane band 216 of near the water front to melt pool 224 of outlet opening 208 or upper surface extension.Hurricane band 216 comprises that closely adjacent periphery is (for example with inner reservoir wall 229, outward flange) (for example, within the approximately 1.3cm of wall, or within the approximately 0.6cm of wall, as at approximately 0.000 of wall, 1cm is within about 1.3cm or about 0.6cm, as leave wall approximately 0.000,1cm or less, or leave wall approximately 0.000,5cm, 0.001,0.005,0.01,0.05,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1,1.1,1.2 or about 1.3cm or larger).Therefore hurricane band 216 is wiped polymer fluid along inner reservoir wall 229, and prevents or reduce the stagnation along inner reservoir wall.Thereby the gel-forming along the inner reservoir wall 229 adjacent with hurricane band 216 reduces substantially.

In an example, agitator 214 with respect to the inside one or more mixed columns 218 of locating of hurricane band 216 (for example comprises, the interval that mixed column 218 leaves inner reservoir wall 229 comprises, but be not limited to, 5cm or less, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or larger, and optionally corresponding to the width of hurricane band 216).A plurality of mixed columns 218 comprise, for example, extend to the tapered pole of agitator ring 220 from outlet opening 208.Mixed column 218 mixes polymer fluid in the interior section of melt pool 224, for example, with respect to hurricane band 216 and inner reservoir wall 229 away from.In other words, mixed column 218 orientate as with inner reservoir wall 229 away from, and polymer fluid is mainly provided by mixed column 218 (with also one or more optional to corner post 219 shown in figure 2) in the mixing of melt pool 224 inside, and polymer fluid carries out along wiping by hurricane band 216 of inner reservoir wall 229 simultaneously.

As further shown in Figure 2, in an example, agitator 214 comprises one or more baffle plates 222.Baffle plate 222 is bored a hole, to allow polymer fluid to pass through flowing of its, for example, towards outlet opening 208.In another example, baffle plate 222 comprises respectively to be provided downwards and the overhead gage and the lower baffle plate (lower baffle plate is blocked by the agitator ring 220 shown in Fig. 2 at least in part) that move upward polymer fluid, therefore polymer fluid is vertically mixed in finisher container 204.

A plurality of features of agitator 214 (for example, mixed column 218, hurricane band 216 and baffle plate 222) cooperation, thereby to mix and reduce and prevent that polymer fluid is in the interior stagnation of finisher container 204, water (with the form of steam) is little by little removed to (for example,, by vent condenser 226) to promote the increase of polymer molecular weight simultaneously.Agitator 214 can have the height of any appropriate.For example, the height of agitator can be about 1m to 30m, or approximately 2 to about 15m, or about 1m or less, or about 1m, 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,18,20,22,24,26,28 or about 30m or larger.Agitator 214 can have the topmost diameter of any appropriate, 1 to 50m according to appointment, or approximately 2 to 25m, or approximately 3 to 15m, or about 1m or less, or approximately 2,3,4,5,8,10,12,14,16,18,20,22,24,26,28,30,35,40,45 or about 50m or larger diameter.Agitator 214 can have the foot diameter of any appropriate, 0.001m is to about 50m according to appointment, or about 0.01m is to about 25m, 0.1 to about 15m, or about 0.001m or less, or about 0.01m, 0.1,0.2,0.4,0.6,0.8,1,1.5,2,2.5,3,3.5,4,4.5,5,6,7,8,9,10,15,20,25,30,35,40,45 or about 50m or larger.

Referring again to the agitator 214 shown in Fig. 2, in an example, agitator 214 comprises agitator ring 220.As shown, agitator ring 220 and one or more connection in mixed column 218 or hurricane band 216.Hurricane band 216 can comprise that closely adjacent periphery is (for example with inner reservoir wall 229, outward flange) (for example, within the approximately 1.3cm of wall, or within the approximately 0.6cm of wall, as at approximately 0.000 of wall, 1cm is within about 1.3cm or about 0.6cm, as at approximately 0.000 of wall, within 1cm or less, or leave wall approximately 0.000,5cm, 0.001,0.005,0.01,0.05,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1,1.1,1.2 or about 1.3cm or larger).One or more bodies that provide support in 220 pairs of mixed columns 218 of agitator ring, hurricane band 216 and baffle plate 222, and therefore these parts are remained in shown arrangement.Additionally, agitator ring 220 optionally mixes polymer fluid.Agitator ring 220, in an example, for example, comprises one or more grooves, breach, blade etc. along the surface (, in inside or outer surface one or more) of ring, so that the mixing being provided by agitator 214 to be provided.

In shown example, agitator ring 220 is remotely located (for example, the outward flange 216 of relative hurricane band is closely adjacent) with respect to inner reservoir wall 229.In other words, the outward flange 216 of relative hurricane band is closely adjacent to wall 229, between agitator ring 220 and wall 229, provides gap.Optionally, agitator ring 220 includes, but not limited to 5cm or lower with the interval of inner reservoir wall 229, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or higher, and optionally corresponding to the width of hurricane band 216.Therefore, along with agitator 214 is in the interior rotation of finisher assembly 200, for example, by the rotation in melt pool 224, agitator ring 220 for example, is separated from inner reservoir wall 229 and the gel that forms (, relative with agitator ring 220) formation along inner reservoir wall 229.By moving inward agitator ring 220, for example, by making its interval away from inner reservoir wall 229, even if having gel along the generation of inner reservoir wall 229, the relative gel of agitator ring 220 is remotely located, and between ring and gel, any mechanical engagement reduces substantially.Therefore, gel is by the minimizing similarly of shifting out engaging.

In a similar manner, and as described herein, mixed column 218 location are away from inner reservoir wall 229.In other words, closely adjacent with respect to the outward flange 216 of hurricane band and inner reservoir wall 229 provides gap between mixed column 218 and inner reservoir wall 229.For example, mixed column 218 comprises with the interval of inner reservoir wall 229, but be not limited to 5cm or less, or about 6cm, 7,8,9,10,11,12,13,14,15,16,17,18,19cm or about 20cm or more greatly and optionally corresponding to the width of hurricane band 216.In the situation that polymer gel is along the one or more formation in mixed column 218, gel is located away from inner reservoir wall 229.Therefore, the gel non-involvement chamber wall 229 on mixed column 218, and do not shift out similarly.In other words, even in the situation that finisher assembly 200 produces gel along inner reservoir wall 229, with the finisher assembly 200 that comprises agitator 214 (thering is remotely agitator ring 220 and the mixed column 218 of location) shown in Fig. 2 substantially prevent otherwise by least with inner reservoir wall 229 any mechanical engagement that to a certain degree the agitator ring 220 (or mixed column 218) of tight adjacent positioned provides.In the running of finisher assembly 200 (for example, for a long time as more than 91 days), remotely the agitator ring 220 of location does not shift out gel from inner reservoir wall 229, and inner reservoir wall 229 correspondingly engages and shifted out with the gel along agitator ring 220 or mixed column 218 formation.

Before herein, describe, the generation of finisher assembly 200 inner gels can cause stopping up and the generation of other polymer of even lower level when gel shifts out.With the configuration shown in Fig. 2, use one or more in the mixed column 218 that separates with inner reservoir wall 229 and agitator ring 220, the joint of formed polymer gel and shift out a large amount of minimizings.The finisher assembly 200 that comprises agitator 214 be configured to that operation extends substantially during (more than 91 days) in the time course that there is no obstruction, promote the manufacture of high-quality (HMW) polymer.

As further shown in Figure 2, in an example, the pipe bend that vent condenser 226 extends to vent condenser 226 by the end at elbow is connected to finisher container 204.In an example, vent condenser 226 comprises vacuum ejector or vacuum generation system, and it is configured to extract out the atmosphere in finisher container 204, as moist (with steam) atmosphere wherein.In another example, steam is supplied to vent condenser 226, for example, there is required moisture content, thereby regulate the amount of the moisture of for example, extracting out from the atmosphere (, separated steam 230) of finisher container 204 by vent condenser 226.For example, the stream of " removal " or supplementing water steam is fed to vent condenser 226 by supplementing water vapor line.Supplementing water steam is reduced respectively or increased, thereby extract more or less steam out for the steam 230 of finisher container 204 interior separation.In other words, by being reduced to the supplementing water steam of vent condenser 226, produce the drier stream of the air under negative pressure, thereby take out other steam from finisher container 204.On the contrary, by being increased to the supplementing water steam of vent condenser 226, produce the humidity stream of air, the steam taking out still less from finisher container 206.By regulating supplementing water steam to the injection in vent condenser 226, control the amount of the separated steam 230 taking out from finisher container 204.Thereby, correspondingly control quality, for example the molecular weight of separated polymer fluid 228.

In addition, vent condenser 226 comprises condenser system, and described condenser system comprises weir, for example, is arranged on the annular weir on interior week of vent condenser.Weir is filled with the stream of cooling water, and it overflows the sidepiece on weir and is injected in the remaining part of vent condenser 226.Cooling water (thering is lower temperature with respect to separated steam 230) thus flow water go out and moisture is removed from finisher container 204 from 230 condensations of separated steam.Remove moisture and allow separated polymer fluid 228 to increase its molecular weight along with the polymerization continuing, this is corresponding to the increase in polymer relative viscosity.In another example, provide one or more injections of crossing over vent condenser 226 as crossing over the water on weir, further to promote the condensation the atmosphere of steam in finisher container 204.

Fig. 3 example finisher nozzle 202, another parts of finisher assembly 200.In Fig. 2, finisher nozzle 202 is given and extends in finisher container 204.Fig. 3 is the partial cross section of finisher nozzle 202.The cylinder 303 of nozzle is cut open along its center line, and while separator spiral 306 wherein provides in side view.Cylindrical tube 303 300 extends to outlet opening 302 from ingate.Cylinder 303 has week 304 in the cylinder that limits the inner chamber extending through from it.As shown in Figure 3, cylinder 303 has the internal area 307 (sectional area of the cylinder of measuring perpendicular to helical axis 308 is described below) of substantial constant between ingate 300 and outlet opening 302.In other words, cylinder 303 is substantially first-class large between ingate 300 and outlet opening 302.In an example, according to the demand of the specific finisher nozzle using together with the finisher assembly 200 for shown in Fig. 2, a part for finisher nozzle 202, adjacent with outlet opening 302 or adjacent with ingate 300 part for example, can there is short tapered girth, as thering is the short taper profile section of diameter rather than monotone variation on short axial length.As shown in Figure 3, in cylinder, week 304 and internal area 307 are substantial constant in the length corresponding to separator spiral 306, as further described herein.

As will be described herein, etc. large cylinder 303 (for example, the internal area 307 with interior week 304 of substantial constant cylinder and substantial constant) cooperate with the mixed flow of isolating polymer fluid and steam with separator spiral 306 (illustrating herein), and therefore separated polymer fluid 228 is delivered to finisher container 204 with separated steam 230.Finisher nozzle 202 prevents the separated steam of polymer 230 reentrainments substantially, thereby substantially prevent accordingly splashing of separated polymer, otherwise its separated steam is along inner reservoir wall 229 reentrainments (as described herein) of the finisher container 204 shown in Fig. 2.

With reference now to Fig. 3,, separator spiral 306 is shown as at least a portion that extends through cylinder 303.As shown, separator spiral 306 comprises a plurality of spiral sections 310 that are connected in series to end with end as shown.The spiral section 310 that can comprise any suitable number in separator spiral 306.In the example shown in Fig. 3, the separator substrate 312 with substantially straight structure is connected with adjacent spiral section 310.The remaining part of the spiral section 310 extending towards outlet opening 302 has the structure of distortion and cooperates so that polymer fluid is separated with steam, thereby for example, so that separated polymer fluid 228 is delivered to finisher container 204, in the situation that not splashing inner reservoir wall 229.

In an example, each spiral section 310 comprises the first and second ends 314,316.Each spiral section 310 in a spiral manner (for example, distortion) extends to the second end 316 from first end 314.As previously described, separator spiral 306 and section 310 thereof are shown in side view (not cutting open); Therefore, first end 314 is substantially perpendicular to the page and illustrates, and the second end 316 is parallel to the page simultaneously.The therefore distortion between these ends 314,316 of the remaining part of each section 310.In the example shown in Fig. 3, each spiral section 310 is from first end 314 to about 90 degree of the second adjacent end 316 distortions.For example, along the outward flange 305 on the top (as shown in Figure 3) of spiral section 310 along with outward flange 305 extends and little by little extends into the page to first end 314 from the second end 316.On the contrary, along the outward flange 305 of the bottom (as shown in Figure 3) of spiral section 310 along with edge extends to first end 314 and little by little extends and leave the page from the second end 316.

In another example, adjacent spiral section 310, for example, when in ingate 300 while starting, Next spiral section 310 on the line towards outlet opening 302, comprises and adjacent second end 316 of previous spiral section 310 first end 314 of about 90 degree of homophase not.Therefore, separator spiral 306 in example shown in Fig. 3 provides fracture (discontinuous) chain of spiral section 310, the helical surface that described spiral section provides distortion separately (for example, clockwise or counterclockwise distortion in identical direction), its end at them is with the pairing relative to each other of about 90 degree.In other words, the second end 316 of spiral section 310 and the first end 314 of last spiral section 310 about 90 degree of homophase not.Optionally, spiral section 310 is by including, but are not limited to, and one or more mechanisms of welding, mechanical interworking etc. are paired with each other.

As further illustrated in Fig. 3, in an example, separator spiral 306 connects at one or more sections of anchors 318 places, thereby by the remaining part of separator spiral 306 (for example,, as the outward flange 305 of each section 310 extending along girth 304) and interior all 304 intervals of cylinder.As further described herein, each spiral section 310 with week in cylinder interval (as gap or the separator space 320) cooperation between 304 be provided for separated steam as shown in Figure 2 the separated relative separated polymer 228 of sending along helical axis 308 of steam 230 the path of advancing isolator (for example, first can be at barrel Flow Structure Nearby, and second portion can flow close to centre or core).In the example shown in Fig. 3, the section anchor 318 of each spiral section 310 by separately all 304 is connected with in cylinder at the second end 316 (or optionally at mid portion of first end 314 or section 310).According to the interval being provided by section anchor 318 (or gap), for separating of the path of steam 230 extend through interior all 304 and outward flange 305 between the separator space 320 that provides.

In an example, section anchor 318 was connected by one or more mechanisms with week 304 in cylinder, included, but are not limited to interference engagement, mechanical cooperation, adhesive, prewelding etc.As shown in Figure 3, in an example, section anchor 318 is along a line setting, for example parallel with helical axis 308 and along lines that in cylinder, week 304 extends.Section anchor 318 provides and is easy to connect each with the section of reaching anchor 318 for welding element along the setting of this line, and therefore easily each of section anchor 318 and spiral section 310 all 304 is connected with in cylinder.As further illustrated in Fig. 3, in an example, for separator substrate 312, provide plate anchor 322.In shown example, section anchor 318 substantial linear of each of plate anchor 322 and spiral section 310 are corresponding.Therefore, each of section anchor 318 and the connection of plate anchor 322 (for example, welding or cooperation) complete with linear mode, for example, with the welding element that extends through arbitrary end of cylinder 303.

As previously described, each spiral section 310, in an example, respectively with cylinder in week 304, for example, be connected with section anchor 318.318 cooperations of section anchor are with interior in position at cylinder 303 by each spiral section 310.Therefore, in the maintenance process of finisher nozzle 202 (for example, remove finisher nozzle 202 for clean or for the online clean process of finisher nozzle 202), comprise that the heating and cooling of the nozzle 202 of separator spiral 306 do not make 306 bendings of separator spiral and a plurality of spiral sections 310 are remained in the orientation shown in Fig. 3.In other words, section anchor 318 (and optionally, plate anchor 322) cooperation is with each spiral section 310 of the interior grappling of cylinder 303 (and optionally separator substrate 312).In other words, by each spiral section 310 of grappling, thereby reduce or prevent the bending of separator spiral 306.Each firmly grappling of spiral section 310 of separator spiral 306 is in place.When the separator nozzle 202 that comprises separator spiral 306 being heated to (and cooling afterwards) in cleaning course, separator spiral 306 is not crooked in cylinder 303.The configuration of separator spiral 306 for example, with the configuration in separator space 320, thereby keeps in the operation lifetime process of finisher nozzle 202, after described operation lifetime process is included in the neutralization of clean operation process.

In operation, the mixed flow of polymer fluid and steam by the ingate 300 shown in Fig. 3 send (for example, from Fig. 1 before shown in continuous polymerization system 100 in forward part).For example, the mixed flow of polymer fluid and steam is delivered to the schematic finisher 114 shown in Fig. 1 from flash vessel 112.As shown in Figure 2, finisher nozzle 202 is delivered to the mixed flow of fluid in finisher container 204 and before sending, mixed flow to be separated into separated steam 230 and separated polymer fluid 228.

Referring again to Fig. 3, first the mixed flow of polymer fluid is delivered in cylinder 303 the ingate 300 of finisher nozzle 202.Mixed flow is sent and to separator spiral 306 along separator substrate 312.For example, because etc. large cylinder 303 (, the internal area 307 of week 304 and substantial constant in the cylinder of substantial constant), along with the mixed flow of polymer and steam is sent by cylinder 303, when fluid is sent to outlet opening 302, its speed substantially keeps or increases.Optionally, interior all 304, for example in the diameter in week, with respect to previous finisher nozzle, reduce, further to increase the shearing (and speed) in the mixed flow of polymer and steam.In an example, with the 17.9cm diameter comparison of previous tapered nozzle, finisher nozzle 202 has the internal diameter of 12.7cm.

When mixed flow moves along separator spiral 306, mixed flow engages series helix section 310.As previously described, each spiral section 310 has the shape (comprise, for example, 90 spend distortions) of distortion.Each spiral section 310, in another example again, (for example, clockwise or counterclockwise) distortion in identical direction.Along with the mixed flow of polymer fluid along and according to each spiral section 310, flow, by the large profile of the consistent grade of cylinder 303, keep the speed of fluid.In other words, for example, because cylinder 303 such as is at large (, not the comprising the taper expanding to outlet from entrance), the speed of mixed flow keeps or increases along with being delivered in cylinder 303, this with in the situation that the conical nozzle reduction expanding is contrary.Spiral section 310 flows by separately following or separated mixing: for example allow polymer fluid to advance along helical axis 308, move to the part outside of spiral section 310 and enter in separator space 320 simultaneously compared with low intensive steam according to the speed of its maintenance.On the contrary, underspeed (thering is the nozzle reducing) along with steam can correspondingly be reduced to provided interval to weeks in cylinder 304 guiding more lentamente.Thereby more intensive polymer fluid 228 keeps substantial linear to flow and from steam 230 separation along helical axis 308.Because 304 for example separate by section anchor 318 in week in each of spiral section 310 and cylinder, steam can easily be advanced along separator space 320, thus and the interval that substantially keeps itself and polymer fluid.Therefore, along with polymer fluid and steam are sent to outlet opening 302, each of spiral section 310 and week 304 in cylinder (waiting large cylinder 303) thus cooperation is separated into separated polymer fluid 228 and separated steam 230 by mixed flow.Outlet opening 302 places at finisher nozzle 202, polymer fluid is mainly sent along helical axis 308, and separated steam 230 is main to be delivered in finisher container 204, as shown in Figure 2 along week 304 in cylinder (and guiding is parallel with helical axis 308 downwards).

In addition, by separator spiral 306 with etc. large cylinder 303 combinations (and the separator space 320 keeping therebetween) provide separated separated steam is guided in separator space 320 and therefore substantially reduce along section 310 polymer fluids of advancing to steam in reentrainment.In other words, thus steam keeps its speed by substantially first-class large cylinder 303 and is directed to and remains on away from the separator space 320 of directed polymer fluid (and along interior all 304).Thereby steam 230 with the separated maintenance of polymer fluid 228 by passing through and sending to finisher container 204 in nozzle 202.

In addition, with the configuration shown in Fig. 3, along with separated polymer fluid 228 is passed through etc. to large cylinder 303 with separated steam 230, guide and be delivered in finisher container 204, any splashing of polymer fluid is limited to melt pool 224 substantially.As discussed above, the isolation of splashing by inner reservoir wall 229 from separated polymer 228.Steam is more low-density and more easily to inner reservoir wall 229, disperses than polymer.Therefore,, by preventing the reentrainment of steam interpolymer, reduce outwards splashing to inner reservoir wall 229.In addition, by the stream of separated steam 230 substantially along helical axis 308 guiding and towards melt pool 224.The lateral velocity component that moves through the separated steam of finisher nozzle 202 the large cylinder 303 such as is passed through and is reduced (with respect to the nozzle expanding).Therefore, along inner reservoir wall 229, by thering is the splashing of steam of the polymer of reentrainment, substantially reduce.Separated polymer 228 (and separated steam 230) guides to melt pool 224 (referring to Fig. 2) by finisher nozzle 202, and will guide to similarly in melt pool 224 from splashing of finisher nozzle 202.

Fig. 4 shows for using polymer finishing device assembly to comprise as shown in Figure 2 the flow chart of method 400 of the finisher assembly 200 of finisher nozzle 202.In describing method 400, with reference to one or more parts described herein, feature, function etc.In situation easily, with reference to the parts, feature, function etc. with Reference numeral.The Reference numeral providing be only example and be nonexcludability.For example, the feature of describing in method 400, parts, function etc. include, but are not limited to, the digital element of corresponding band described herein, corresponding feature (with numeral with without both of numeral), and their equivalent.

At 402 places, the mixed flow of steam and polymer fluid is guided through to the finisher nozzle 202 that band has the cylinder (for example, cylindrical tube) in week 304 in substantial constant cylinder.As described herein, in an example, substantial constant between all 304 ingates 300 at cylinder 303 and outlet opening 302 in cylinder.At 404 places, the mixed flow of steam and polymer fluid is combined in the cylinder of substantial constant, week 304 be separated into separated steam 230 and separated polymer fluid 228 with separator spiral 306.In an example, mixed flow separation is comprised: mixed flow is sent along separator spiral 306.In the cylinder of substantial constant, week 304 is when mixed flow 300 is kept to the speed of mixed flow from ingate when outlet opening 302 is sent.Steam is separated from mixed flow, and radially outward moves in the separator space 320 forming between week 304 in each spiral section 310 and cylinder (for example, by one or more by section anchor 318 of weekly interval in spiral section 310 and cylinder).When keeping the speed of mixed flow, steam easily moves in cylinder week 304 for example to separator space 320, and the mixed flow (polymer fluid) of remaining part flows dividually along the helical axis 308 of separator spiral 306 simultaneously.

Method 400 can comprise: at 406 places, separated polymer fluid 228 is guided to container, as shown in Figure 2 in finisher container 204.Guide separated polymer fluid 228 to comprise, at 408 places, separated polymer fluid is delivered to the melt pool 224 of the polymer fluid in finisher container 204.In another example, separated polymer fluid is guided to finisher container 204 to be comprised, at 410 places, according to the cylinder 303 with week 304 in the cylinder of substantial constant, limit separated polymer fluid to melt pool 224 splash and by inner reservoir wall 229 with splash isolation.In other words, in the cylinder of substantial constant, week 304 will guide and therefore reduce the cross stream component of separated steam 230 to melt pool 224 under the flow direction of separated steam 230.Therefore any polymer fluid of the separative steam 230 of reentrainment is guided in melt pool 224, and the situation that is not so good as to have the nozzle reducing is towards inner reservoir wall 229.Additionally and as described herein, in the cylinder of substantial constant, week 304 cooperates with separator spiral 306, concept stock comprises for example its cooperation in separator space 320, so that steam is easily separated from polymer, and therefore do not having as shown in Figure 2 in the situation that the separated interior reentrainment of steam 230 is sent separated polymer fluid 228.By separated polymer fluid 228 substantially along the line consistent with helical axis 308 in the situation that have substantially reduce or minimized cross stream component to melt pool 224, send, itself otherwise separated polymer fluid 228 (or polymer fluid of a part) is sent to inner reservoir wall 229.

Several selections for method 400 are as follows.In an example, the steam of guiding mixed flow comprise by steam for example guide to the outward flange at separator spiral 306 that each the edge by spiral section 310 forms with tin in separator space 320 between all 304.In another example, mixed flow being used in to separator spiral 306 in cylindrical tube 303 is separated into separated steam 230 and comprises with separated polymer 228 fluids: a plurality of spiral sections 310 guiding by the polymer fluid of mixed flow along separator spiral 306.The polymer fluid of mixed flow is comprised along spiral section 310 guiding: a plurality of spiral section directs polymer fluids that connect along each the first and second end 314,316 places of the spiral section 310 separately.Before herein, describe, in another example, first end 314 and the second end 316 the being close to phase (for example,, with 90 degree) that differs from one another.

In another example, restriction is splashed and is isolated inner reservoir wall 229 and comprises: according to week 304 in the cylinder of substantial constant, by separated steam 230 and the longitudinal axis of separated polymer 228 along cylinder 303, for example the axial melt pool 224 consistent with the helical axis 308 of separator spiral 306 guides downwards.In another example again, inner reservoir wall 229 and the isolation of splashing are comprised: according to week 304 in the cylinder of substantial constant, reduce radially (for example, horizontal) component of the separated steam 230 that is guided through finisher nozzle 202.In other words, by the cylinder not reducing (week 304 in the cylinder of substantial constant) is provided, separated steam 230, replaces sending in the mode outwards expanding, and the downward component substantially that guides to melt pool 224 for using in generation is sent.Therefore, also any polymer fluid of the separative steam 230 of reentrainment is down guided in melt pool 224.

In another example, method 400 comprises: use finisher agitator 214 as shown in Figure 2 to stir polymer fluids 228.As shown, finisher agitator 214 is in the interior rotation of finisher container 204.In another example, separated polymer fluid 228 use finisher agitators 214 are stirred and are comprised: by polymer fluid with wiping along inner reservoir wall 229 in hurricane band 216 wiping district.The outward flange of hurricane band and the tight adjacent positioned of inner reservoir wall 229 (for example,, in about 0.6cm or about 0.7cm).In another example again, separated polymer fluid 228 use finisher agitators 214 are stirred and are comprised: by polymer fluid with wiping along inner reservoir wall 229 in hurricane band 216 wiping district.

Agitator ring 220 is connected with one or more mixed columns 218, and itself and inner reservoir wall 229 are with respect to remotely locating with the hurricane band of inner reservoir wall 229 tight adjacent positioned.For example, as shown in Figure 2, agitator ring 220 and described one or more mixed column 218 are inwardly located with respect to inner reservoir wall 229 and hurricane band 216.Closely adjacent with respect to hurricane band 216 and inner reservoir wall, described one or more mixed columns 218 and agitator ring 220 separate from inner reservoir wall.Agitator ring 220 and one or more connection in hurricane band 216 or one or more mixed column 218.Separated polymer fluid 228 use finisher agitators 214 are stirred and comprised: separated polymer fluid is used in the mixed zone away from inner reservoir wall 229 the one or more mixed columns 218 that are connected with hurricane band 216 mix.

In another example again, stir separated polymer fluid 228 and comprise: by inner reservoir wall 229 and the isolation of agitator ring.As described herein, in an example, agitator ring 220 is remotely located with respect to inner reservoir wall 229.Therefore, in the running of finisher assembly 200, along with gel is along inner reservoir wall 229 accumulation, agitator ring 220 by not with the gel phase mutual effect forming along wall 229, for example, until far become the run duration (, after moving continuously with approaching of heaven 90) of (far along into) finisher assembly 200.Similarly, any gel phase producing along agitator ring 220 is remotely located for inner reservoir wall 229.Therefore, along the gel of inner reservoir wall 229, by the interception of agitator ring 220 or the gel on agitator ring 220, by the interception of inner reservoir wall 229, reduced, the shifting out of gel reduced and gel to sending accordingly also in the cylinder 213 of finisher assembly 200 reduced.Obstruction and low-quality polymer product are arranged substantially and (are for example reduced with this, in the situation that recessed from inner reservoir wall 229 of finisher nozzle 202 and mixed column 218 and agitator ring 220, that reduces splashes), and the service life scope of finisher assembly 200 increased significantly before needs are clean.

In another example again, method 400 also comprises finisher nozzle 202 clean.Clean for example comprising, by finisher nozzle 202 (, cylinder 303 and separator spiral 306) heating.In addition the warpage that, each in a plurality of spiral sections 310 of separator spiral 306 is not subject to being caused by heating (and heating afterwards cooling) suppresses.Suppress to comprise each in a plurality of spiral sections 310 is anchored into week 304 in cylinder.In an example, a plurality of spiral sections 310 have along connecting in the situation of week 304 a plurality of corresponding section of anchors 318 that are connected (for example,, by electric welding, machinery cooperation, interference engagement etc.) in cylinder with week 304 in cylinder respectively.
