The specific embodiment
By the following specific embodiment the utility model is further specified, but not as restriction of the present utility model.
Embodiment 1, extraction tower
Extraction tower described in the utility model is by upper shell, middle cylindrical shell and lower shell are formed, combine as a whole from top to bottom and inside communicates, heater is installed in the cylindrical shell, wherein, steam inlet 16 is installed in the upper shell top, after steam enters, flow into inner barrel auger 6, pass through straight section inner barrel 8 more successively by steam inlet tube 17, heating tube 18 in the middle of inner barrel conelet 10 and the steam, finally the condensation-water drain 19 from lower shell flows out.
The application of embodiment 2, extraction tower
Polyamide fibre PA6 section adds from the top 2 section import distributors of this extraction tower, evenly distribute through the conical distributor that is installed in 2 section import distributor bottoms, be assigned on the cross section of this extraction tower, and rely on deadweight from top to bottom evenly to flow, desalted water then enters this extraction tower inside from the 20 desalted water imports of taking off of this extraction tower bottom, under the heat effect of internal heater, the desalted water temperature progressively raises, and flows in opposite directions with section from bottom to up.The conical distributor of 2 section import distributor bottoms is bucket property structure, it mainly acts on is the shunting section, prevent directly impact downwards of section, relax the process of section charging, the dirt bits that minimizing produces because of the section high-speed impact, and be beneficial to section and in this extraction tower, form uniform laminar flow, be convenient to polyamide fibre PA6 section in descending process, fully contact with the desalted water that comes from the bottom, evenly extraction.
Device of the present utility model adopts steam as heating source, and 16 steam inlets at this device top enter in this device interior heater certainly, derives condensed water from bottom position 19 condensation-water drains of this device at last.For the uniformity that guarantees to heat on the cross section, steam does not directly contact with water with section, but adds device inside in inside, by the mode of indirect the section water in the tower is carried out uniform gradient-heated.
Device of the present utility model, be illustrated in figure 1 as " string shape " structure, this flows downward no dead angle in the mode of approximate laminar flow with regard to having guaranteed polyamide fibre PA6 section in this extraction tower, the polyamide fibre PA6 section that has guaranteed advanced tower goes out earlier, and this is to guarantee the inhomogeneity key of chipping qualities.And when polyamide fibre PA6 section entered annular space between 7 straight section outer cylinder bodies, 8 straight section inner barrels between 5 outer cylinder body augers, 6 inner barrel augers, flow area narrowed down, and the flow velocity of section and extraction water is accelerated, and convection current aggravates, thereby has improved extraction efficiency greatly.Then, when section entered between 9 outer cylinder body conelets, the 10 inner barrel conelets, flow velocity slowed down.Through the extraction of several same structures unit, can obtain high-quality section like this.
It at the bottom of the tower of device of the present utility model heating jacket structure, 12 heating jackets heat the outlet at bottom section of this extraction tower, this heating jacket is provided with two circles altogether, under the effect of its water column pressure, can make the temperature of desalted water reach 115～120 ℃, and the raising of this temperature is very helpful to the extraction of caprolactam monomer in the polyamide fibre PA6 section and oligomer, thereby has improved chipping qualities and guaranteed to leave the equilibrium of the polyamide fibre PA6 section internal temperature of this extraction tower.
The desalted water that contains a large amount of caprolactam monomers and oligomer heat after the device extraction of the present utility model, behind the shunt filtering of 1 filter, overflow this extraction tower, the amount that the desalination water yield of overflowing this extraction tower is added mouthful according to the amount of these extraction tower bottom 19 desalted water imports and middle and upper part desalted water is determined.
