Oil product through pipelines alpha-olefin ultra-high molecular weight frictional reducing polymer is thermopositive reaction when polyreaction, so its preparation method is must be under cold condition.Method commonly used now, the one, adopt special coating material that polymerization single polymerization monomer and catalyzer are made the microcapsulary that microcapsule place heat transferring medium, this method heat interchanging area is big, heat transferring medium be continuously and volume big, can rapidly reaction heat be removed, but deficiency is the equipment complexity, and investment is big, yields poorly; The 2nd, coil pipe is set in reactor, utilize the interior cooling medium flowing of coil pipe to remove the coil tube type polymerisation process of reaction heat, and this kind method heat exchange efficiency is undesirable, reaction product is difficult for taking out, and yields poorly, and production efficiency is not high; The 3rd, our company is in " the explosion-proof polymerizing reactor of mass polymerization " (the application number 03150258.X) of application on July 23rd, 2003, it is polymerization single polymerization monomer and catalyzer cloth to be drenched on the interior cylinder that has the fluid interchange medium to pass through carry out polyreaction, and reaction product is scraped by scraper.This method is easy, and device is simple, heat exchange efficiency height, energy continuous production, production efficiency height.But being applicable to reaction product, this method becomes the solid situation, long because of becoming the solid time, and make the production cycle long, though the energy continuous production has also limited production efficiency.
Summary of the invention
Heat exchange efficiency height when the objective of the invention is to invent a kind of alpha-olefin ultra-high molecular weight polymerization liquid and being liquid, can continuous production, product is convenient to remove and production efficiency is high preparation method and device.
The present invention is convenient to remove from improving heat exchange and product, the method that is adopted is to have in the closed reactor that adds the refrigeration cycle chuck adding respectively through pre-cooled polymerization single polymerization monomer and catalyst by proportion, stir to rouse the inertia cold air, reaction solution is undertaken inserting the low-temp reaction case behind the airtight package by liquid packing machine.Specifically be polymerization single polymerization monomer to be precooled to-30～0 ℃ to add closed reactor, catalyst by proportion also adds reactor, reactor cools off in the circulation chuck circulating nitrogen gas that passes to-30～0 ℃ outward, and blast pipe with the pressure of 0.2～0.5MPa by nitrogen with the nitrogen of this temperature and blast the reactor bottom and stir, begin to pump into the automatic liquid packaging machine that places nitrogen environment after 5 minutes and in 2.5 hours, reaction solution be wrapped in the airtight packing bag in reaction, after packing bag is placed cryostat.Present method has been owing to carried out precooling to polymerization single polymerization monomer in advance, and in reactor, the refrigeration cycle chuck arranged outward, in have cool nitrogen to blast, its reaction heat can fully be taken away fully, can not produce implode, and high heat exchange efficiency is arranged.Polyreaction then is continuously and carries out in different vessels, polyreaction in reactor is main, but because reaction just began to pack after 5 minutes, just is extended down in the packing bag so it continues reaction, and packing bag places cryostat, so its reaction heat still can be got rid of.Simultaneously because controlling packet is contained in initial 2.5 hours of the reaction, remain liquid in this time reaction product, at most in the end reaction product viscosity but still can encapsulate in device of full automatic packaging more greatly, this product output easily continuously that is highly advantageous to.Liquid, solid-state different is looked in the adding of catalyzer.If solid catalyst then can be divided in catalyzer in certain nitrogen environment container in proportion, from the dog-house that is positioned at reactor top (is connected but will seal) adding reactor with container.For convenient, unified, solid catalyst can be liquefied, together in proportion catalyzer is added reactor with other liquid catalyst with proportioning pump.The method of solid catalyst liquefaction is that it is suspended in varsol or certain the special solution, varsol is liquid alkane and aromatic hydrocarbon, comprise pentane, hexane, heptane, octane, nonane, decane and hexanaphthene, benzene,toluene,xylene etc., special solution mainly is the proportioning pentane, and it is made up of 30～50% Skellysolve A and 50～70% iso-pentane.Need not conventional method in reactor and to adopt the method for the cold nitrogen of drum be a kind of way of killing two birds with one stone to the stirring of polymkeric substance.When cold nitrogen is evenly blasted the bottom of reactor with the pressure of 0.2～0.5MPa, because different with the proportion of polymkeric substance and the enough pressure of nitrogen, nitrogen just can upwards flow at the bottom of still equably fast, makes the temperature of polymkeric substance descend the effect of playing cooling and stirring simultaneously.Certainly the nitrogen that blasts will enter in the interior polymkeric substance of reactor equably, to its device that blasts nitrogen strict requirement will be arranged.
According to aforesaid method, device of the present invention as shown in Figure 1.It is to have made significant improvement on the basis of raw material storage tank 1, raw material feeding pump 37, reactor 11, catalyzer storage tank 18,22 and catalyzer charge pump 17 in routine.The first raw material storage tank 1 outlet at bottom by the road, material outlet valve 38 connects raw material feeding pump 37 back and connects raw material precooling imported valve 5, precooling unit 6 by pipeline; It two is that precooling unit 6 is advanced the low-temp reaction still 11 that still valve 13 connects again outwards thermal insulation layer and refrigeration cycle chuck 10 by raw material precooling outlet valve 8, raw material, stretches into a nitrogen bulging pipe 45 to reactor 11 bottoms by reactor 11 top center; It three is to have discharge port to go out still valve 32 and wrapping machine fresh feed pump 31, wrapping machine charging valve 29 to automatic liquid packaging machine 30 through reaction solution from reactor 11 bottoms, and below this automatic liquid packaging machine 30 low-temp reaction case 35 is arranged.Precooling unit 6 as shown in Figure 2, it is vertically to be evenly distributed with one group of many cooling tube 42 between a pipe shape housing 39 two ends (concrete quantity is decided on housing 39 diameters and cooling tube 42 diameters, be that cooling tube is many in principle, precooling is effective), these cooling tube 42 two ends have overhead gage 40 and lower baffle plate 43 to weld with it respectively and two baffle plates 40, porosely on 43 communicate with every cooling tube 42, last lower baffle plate 40,43 with housing 39 inwalls welding after respectively weld a hemispherical upper cover 41 and a following capping 44 again at housing 39 two ends, last, following capping 41,44 dome centers each porose and welding precooling nitrogen outlet 7 and precooling nitrogen inlet 9, two baffle plates 40 in the both sides up and down of housing 39, each porose and welding precooling material outlet valve 8 and precooling material inlet valve 5 in 43.Reactor cools off circulation chuck 10 (see figure 3)s outward, and to be that hollow similar to reactor 11 shapes is placed in reactor 11 outer and external thermal insulation arranged, it is the welding of periphery suitable for reading and reactor 11 tops, its underpart has cold nitrogen to advance to overlap valve 33, and top has cold nitrogen to go out to overlap valve 28.Have tensimeter 12, raw material to advance still valve 13, catalyzer on reactor 11 tops and advance still valve 16 and stir cooling nitrogen bulging pipe 45 and pass, the bottom liquid that responds goes out still valve 32 pipes, sewage draining valve 34 pipes and cold nitrogen and advances to overlap valve 33 and pass.Nitrogen bulging pipe 45 (see figure 4)s are the pipes that extend into reactor 11 bottoms from reactor 11 top center, the lower end of the pipe porose diameter that communicates with pipe in center that vertically is connected is equal to the disk of reactor 11 internal diameters, the a lot of spray nitrogen of uniform distribution hole 46 on the dish, and dish and unsettled rear perimeter edge in 11 ends of reactor and the welding of reactor 11 inside circumferences.The 46 fens circles in spray nitrogen hole on the dish are beaten, and should stagger mutually in the spray nitrogen hole 46 of adjacent turn.For making stirring and heat extraction effective, Kong Yi is many, and the distance between the hole is as far as possible littler, and the aperture then can not be too little, should be between 2～10mm.General aperture and pitch of holes sizableness are advisable.The nitrogen bulging pipe 45 of this spline structure, reactor fluid valve 32 just must be installed on the dish of nitrogen bulging pipe 45 of reactor 11 sides.For discharging lodges in a small amount of reaction solution at 11 ends of reactor, will connect a wash water
