Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provides a kind of vibrational power flow reasonable, and greatly increase the contact area between liquid vapour, reaction speed is fast, promotes the Novel liquid-phase tack producing device of melt quality well.
Technical scheme: in order to solve the problems of the technologies described above, a kind of Novel liquid-phase tack producing device described in the utility model, it comprises disk reactor, melt cooler and filter, they connect successively according to the order of sequence, described filter is connected with liquid-phase tackifying reactor top by pipeline, described liquid-phase tackifying reactor comprises up-narrow and down-wide barrel-type casing, charging aperture is provided with in described case top, bottom is provided with discharging opening, distributor is provided with above described enclosure interior, joint pin is provided with below described distributor, described joint pin is provided with liquid-phase tackifying conically shaped body that row are arranged with one heart from top to bottom, the arithmetic progression that the radius size of described liquid-phase tackifying conically shaped body is 50-80cm by tolerance from top to bottom successively increases, angle between the outer surface of described liquid-phase tackifying conically shaped body and connecting rod is 60 °, the vertical height of described each liquid-phase tackifying conically shaped body is between 10-15cm.
Described liquid-phase tackifying conically shaped body is provided with 3 or 4.
Gap is provided with between described distributor and minimum liquid-phase tackifying conically shaped body.
The bottom surface of described housing is lower domatic bottom surface.
Pipeline between described filter and liquid-phase tackifying reactor is provided with melt booster pump.
The utility model is provided with the bullet of superposition cone cylindricality multilayer drop with one heart in housing, the low sticky melt of PBT enters from the top of housing and distributes, utilize self gravitation equably stably natural landing is downward gradually at leisure from the surface of bullet, form melt film, like this by the drop of each layer cone, guarantee to form the uniform continuous film of thickness.Simultaneously, the utilidor of heating agent chuck is set up online Viscosity Monitoring, the viscosity of the low sticky melt sending into thickening reactor is controlled between 0.5-0.6dl/g, the too high thermal degradation that can aggravate melt melt long distance delivery of viscosity, too low, the tackifying ability of liquid-phase tackifying reactor can be exceeded, after causing thickening, melt does not reach the target viscosities requirement needed for spinning, and this viscosity can carry out stability contorting by the low cohesive end speed of agitator and vacuum regulating disk reactor.For the thermal degradation of melt in course of conveying is dropped to minimum, through test, on-line temperature monitoring is set, to ensure that the melt conveying temperature in utilidor is strict controlled between 225-245 DEG C, specifically by regulating melt jacket pipe heat medium temperature and melt cooling actuator temperature to realize, and the vacuum of liquid-phase tackifying reactor and feed inlet and outlet material viscosity also realize " tandem " on DCS controls.Viscosity-increasing reactor interior reaction temperature is between 235-255 DEG C, and the time of staying, operating pressure was at 0.15-0.20Kpa between 0.5-1.3h.After thickening, flow out after monitoring from discharging opening, by gear pump, height is glued melt and send device for spinning spinning.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model vibrational power flow is reasonable, adopt the liquid-phase tackifying conically shaped body arranged with one heart, and the arithmetic progression that the radius size of liquid-phase tackifying conically shaped body is 50-80cm by tolerance from top to bottom successively increases, angle between the outer surface of described liquid-phase tackifying conically shaped body and connecting rod is 60 °, the vertical height of described each liquid-phase tackifying conically shaped body is between 10-15cm, considerably increase the contact area between liquid vapour like this, small molecule by-product can discharge reaction system fast, effectively accelerate reaction speed, shorten melt residence time, and ensure melt first in first out, make melt in reactor, obtain consistent reaction condition, improve the quality of melt well, set up online Viscosity Monitoring and on-line temperature monitoring, control accuracy can be improved further.
