Description
Technical field
The present invention relates to a kind of nozzle.
Background technology
The polymer solution that solution polymerization process obtains (for example EP rubbers solution) generally adopts elutriation method isolating polymer and solvent at present; Be about to polymer solution under certain pressure; Spray in the cohesion still hot water by one or more nozzles; With solvent vaporization and take out of outside the still, polymer then is gathered into macroparticle or grumeleuse is separated out from polymer solution with steam, and separates with polymer solution and to get in the water.Wherein, the solution nozzle is critical equipment, and the quality of its performance is influence steam stripped efficient, equipment energy consumption and economy directly.
Traditional stirring cohesion still majority all adopts single fluid (polymer solution) nozzle; The shearing force that needs to rely on stronger mechanical agitation to produce is cut and dispersing polymer solution; Therefore very high to the mechanical agitation Capability Requirement, thus cause having improved speed of agitator and power, and then increased energy consumption.On the other hand, because polymer solution sprays in the cohesion still, so steam stripping efficiency is low without preheating.
CN101486022A discloses a kind of prewarming internal mixed nozzle, and is as shown in Figure 1, and this nozzle comprises central tube 6, interior endless tube 3 and outer tube 7; Outer tube 7 is positioned at the outside of central tube 6, and interior endless tube 3 is between central tube 6 and outer tube 7, and said central tube 6 has expansion segment 1, contraction section 2 and mixer 5; And the rear end of central tube 6 is provided with reaction-ure inlet 9; Expansion segment 1 is positioned at the front end of central tube 6, and mixer 5 is connected with expansion segment 1 through contraction section 2, and mixer 5 is provided with two rows or many rows' air admission hole 4; Angle between this air admission hole 4 and central tube 6 axis is 30～90 °, and the inclination angle is 0～70 °; Leave the space between the front end of interior endless tube 3 and expansion segment 1 middle part, the rear end is connected with central tube 6; The front end of outer tube 7 is connected with the head of the expansion segment 1 of central tube 6, and the rear end is connected with the afterbody of central tube 6, and the rear portion of outer tube 7 is provided with gas feed 8.
Above-mentioned prewarming internal mixed nozzle is when work; Atomizing steam or oxygen get in the outer tube 7 from gas feed 8; Flow to expansion segment 1 at a relatively high speed through outer tube 7 and interior endless tube 3; And turn through the space between interior endless tube 3 and the expansion segment 1 and to flow through expansion segment 1, make gas obtain preheating, the wall temperature of jet expansion reduction simultaneously; Annular space in high velocity air gets into then between endless tube 3 and the mixer 5; Evenly get in the mixer 5 at a high speed through air admission hole 4; With the feedstock oil or the gaseous hydrocarbon rapid mixing that get into central tube 6 from reaction-ure inlet 9; Form uniform foam flow, this foam flow forms the reaction logistics of wellatomized mist torch or mixing homogeneous through contraction section 2 and expansion segment 1 ejection at a high speed.This prewarming internal mixed nozzle relatively is applicable to petroleum catalytic cracking technology and natural gas oxidative pyrolysis system acetylene technology; But be not suitable for the technology of isolating polymer and solvent; Because in the process of steam and solution rapid mixing; Form bubble or hollow easily, the phenomenon that makes the quick-fried spray of appearance in the process of ejection, and also the said nozzle existence is prone to stop up, difficult problem of clearing up.
Summary of the invention
The object of the present invention is to provide a kind of nozzle that can be used in steam stripping coacervation and separation device for polymer solution, this nozzle can improve steam stripping efficiency and can reduce equipment energy consumption.
The invention provides a kind of nozzle; Wherein, this nozzle comprises inner catheter and outer catheter, and said outer catheter is fixedly connected around said inner catheter setting and with said inner catheter; Be formed with the space between said outer catheter and the said inner catheter; The front end of said inner catheter is provided with first injecting-unit that is communicated with said inner catheter, and said inner catheter be provided with first the inlet, the front end of said outer catheter is provided with second injecting-unit that is communicated with said outer catheter; And said outer catheter is provided with second inlet, and first spray-hole of said first injecting-unit is positioned at second spray-hole of said second injecting-unit.
When the polymer that utilizes said nozzle to polymer solution separates with solvent, at first said polymer solution is imported in the said inner catheter through said first inlet, simultaneously steam is imported in the said outer catheter through said second inlet.In the course of the work; Steam in the said outer catheter carries out preheating to the polymer solution in the said inner catheter; Polymer solution after the preheating sprays from said first injecting-unit; The polymer solution of this ejection is broken up from the steam of said second injecting-unit ejection simultaneously, forms in oil droplet and the entering cohesion still, and said steam is carried most of vaporization secretly when breaing up said polymer solution solvent gets into the condenser system of condensing still.
Because nozzle provided by the invention can carry out preheating to polymer solution before the polymer solution ejection; So solution the time can reach the solvent needed temperature of vaporizing in ejection; From being ejected into the moment that gets into cohesion still hot water; Most of solvent all is flashed vaporization, thereby has improved steam stripping efficiency.In addition; Because polymer solution is when spraying from first injecting-unit; The steam that quilt sprays from second injecting-unit is simultaneously smashed or is atomized; Form the oil droplet of even particle size, get final product so the cohesion still only needs general mixer under lower rotating speed and power, to keep the normal suspension of polymer beads and flow, thereby reduced energy consumption.And, because steam does not mix in nozzle interior with solution, so can not form bubble or hollow, the phenomenon of quick-fried spray can not appear in the process of ejection yet.
Other features and advantages of the present invention will partly specify in the specific embodiment subsequently.
