Description
Technical field
The utility model is specifically related to a kind of extraction tower for caprolactam.
Background technology
Present domestic common extraction tower many employings long cylinder structure, inner without heater, portion's heating jacket of only setting a trap on urceolus, heat transfer area is little, and temperature regulates difficult.And internal structure dead angle is many, thus have a strong impact on extraction quality and the efficiency of polyamide fibre PA6 section.Caprolactam monomer and oligomer still containing about 10% in the section that polyamide fibre PA6 post polymerizer is produced, the existence of these caprolactam monomers and oligomer, cannot cut into slices for the production of the polyamide fibre PA6 of high-quality long filament level high-speed spinning at all.
Application number 201020215395.4, provide a kind of nylon PA 6 polymerization novel extraction tower, interior heater is provided with in this device inside, interior heater runs through the device of this utility model from top to bottom, this extraction tower to some extent solves the problems of the prior art, but its effect of extracting is unsatisfactory.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of extraction tower, heat exchange can be reached even, the object that extraction efficiency is high.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of extraction tower, comprises conical head, cylindrical tube, multiple canister unit and flanged conical head from top to bottom successively, adopts detachable connected mode between multiple canister unit; Described conical head top is provided with charging aperture; Described cylindrical tube top is provided with temperature-measuring port one, and bottom is provided with water inlet one; Described canister unit is provided with hot water inlet, heat(ing) coil, hot water outlet, temperature-measuring port and extraction ring from top to bottom successively; Described flanged conical head inwall is provided with inner cone, and outer wall is provided with at least two water inlets two, and bottom is provided with discharging opening.
Preferably, the quantity of described canister unit is six.
Preferably, the height of described conical head is 1/3rd of flanged conical head height.
Preferably, the quantity of described water inlet two is three, and the height of three water inlets two is different.
Preferably, the height of described cylindrical tube is the twice of described canister unit height.
Preferably, the impeller for disperseing is provided with in described cylindrical tube.
The utility model advantage is compared with prior art:
The utility model structure is simple, and the mode passing into hot water in heat(ing) coil heats, and homogeneous heating is effective, and saving water resource; Be flanged conical head at the bottom of the tower of extraction tower, which is provided with three highly different water inlets, its effect is better than a water inlet; Therefore effect of extracting of the present utility model is improved, laboratory test in the middle of, canister unit be six for extracting caprolactam time, extraction yield can reach 96%, than the extraction tower extraction yield height 2-5 percentage point of other kind.
