Description
Technical field
The utility model is the preparation facilities of a kind of high alpha-olefin drag reducing polymerization powder of oil product through pipelines drag reduction.Relate to general chemical devices and tubing system field.
Background technology
Flow improver (Drag reducing-agent) is the chemical additive that is widely used in oil pipeline that grows up a kind of phase late 1970s.Under turbulent-flow conditions, inject the flow improver of ppm level in the pipe transporting fluid, just can reduce fluid flow resistance greatly, thereby reach the purpose that improves the pipeline throughput rate or reduce the pipeline operating pressure.Wherein, play the polymkeric substance of a kind of pectination ultra-high molecular weight of being generally of drag reduction effect high alpha-olefin.Generally obtain frictional reducing polymer by solution polymerization or mass polymerization.The flow improver product must have flowable, pumpability and easy oil-soluble characteristics, could satisfy the requirement of using.Flow improver product, ie in solution form and slurry form that two kinds of forms have been arranged at present.The former is by solution polymerization process, or mass polymer is dissolved in the specific solvent and obtains; The latter is ground into powder by pulverizing at ultralow temperature technology with frictional reducing polymer with mass polymer, is mixed into then in a kind of liquid system that contains the number of chemical auxiliary agent and makes a kind of slurry product.These two kinds of products respectively have its relative merits.Solution-type flow improver effective concentration low (the highest can only reaching about 10%), viscosity height (can up to 100,000 centipoises), but stability in storage is good, and operation and maintenance is simple during rig-site utilization; Slurry flow improver effective concentration higher (can reach 30～40%), viscosity low (usually about 2,000 centipoises), but poor storage stability, operation and maintenance is loaded down with trivial details during rig-site utilization.
The frictional reducing polymer that mass polymerization obtained is a kind of strong viscoelastic solid, and its pulverizing is carried out under the condition of ultralow temperature of cooled with liquid nitrogen usually.Frictional reducing polymer particulate after pulverizing must become fluid product with the mixing of number of chemical auxiliary agent through stirring pulping very soon, otherwise polymer particles is with very fast bonding again one-tenth piece.Nonetheless, polymer particles in the slurry also is easy to assemble under the condition of leaving standstill or in transportation, cause slurry layering to occur, thereby must carry out the tank switching operation when using at the scene, and also occur the blockage problem of injection pump in the injection process easily.Therefore, bring very burden for flow improver application at the scene.
The utility model content
The purpose of this utility model is the effective content height, accumulating convenience, safety of a kind of mass polymerization frictional reducing polymer of design, the preparation facilities of stable powder that rig-site utilization is easy.
The utility model is many deficiencies that high viscoelastic body exists at the product of high alpha-olefin frictional reducing polymer mass polymerization, abandon both dangerous also uneconomic pulverizing at ultralow temperature device, and take the device that continuation is processed under the normal temperature, the polymkeric substance that makes mass polymerization is with the powder morphology stable existence.Its preparation facilities is made up of airheater 14, strengthening airflow dryer 17, drying tube 18, blower fan 19, cyclonic separator 20 in feeder 1, wet tank 2, I and II colloidal mill 4,7, strainer 9, dispersion agent powder storage tank 16 and the intensified type pneumatic drier.The concrete formation of this system as shown in Figure 1.It is feeder 1 and wet tank 2 by the road, wet tank outlet valve 3 is connected with one-level colloidal mill 4 inlets, these one-level colloidal mill 4 exit end by the road, the one-level colloid grinds mouthful valve 5, secondary colloidal mill inlet valve 6 is connected with secondary colloidal mill 7 inlets, 7 outlets of secondary colloidal mill are through secondary colloidal mill outlet valve 8, pipeline is connected with strainer 9 inlets, strainer 9 bottoms are connected with tap hole valve 11 and moistening solia particle discharge port valve 10, this discharge port valve 10 connects the inlet to strengthening airflow dryer 17 by the road, have solid dispersion powder storage tank 16 also to connect two inlets in addition of strengthening airflow dryer 17 by pipeline simultaneously, and the outlet of strengthening airflow dryer 17 is connect to the cyclonic separator 20 that blower fan 19 and hopper 21 are arranged by drying tube 18 through outlet valve 15 and airheater 14 that airstrainer 13 arranged.Colloidal mill 4,7 in the native system, airheater 14, strengthening airflow dryer 17, drying tube 18, blower fan 19, cyclonic separator 20 are city's pin product of common usefulness, and feeder 1 also for city's pin product, is just selected spiral feeder for solid materials for use.The colloidal mill here generally has two-stage, i.e. the colloidal mill serial connection.Strainer 9 is then special because of there being particular requirement to need.Must filter at the fineness scope internal classification of solid particulate as requested, generally between 80～200 orders, divide 2～3 grades of filtrations, 2～3 layers of filtering net promptly are set.The structure of its two-layer filtering net is shown in Fig. 2,3.It is in the bottom is connected with the filter cabinet 33 of reservoir 27 the rectangular 80 order filtering nets 24 of semicircle and the rectangular 200 order filtering nets 26 of semicircle to be installed from top to bottom, at this two filtering net 24, install one along each cooperation of rectangular direction of net on 26 and go up feeding screw 23 and a following feeding screw 25, filtering net 24,26 right-hand member is than feeding screw 23, one section of 25 weak point, to make discharge port, two feeding screws 23,25 axle 34 is positioned on filter cabinet 33 bodies respectively and external drive source, the outer of spiral contacts with filter cabinet 33 inwalls, with filtering net 24,26 coincide, contact, above filter cabinet 33 left ends, material inlet 22 is arranged, there is vision slit 31 the right-hand member top, there is material outlet 32 the strainer below of corresponding vision slit 31, in reservoir 27 bottoms of rectangular parallelepiped tap hole 28 is arranged.Filtering net 24,26 has outwardly-bent 90 degree at the two ends of semicircle card articles with filter net cage 33 phase positions on groove 29, lower groove 30 cooperate and locate filtering net 24,26.The filtering net 24,26 of this kind structure can be extracted out from filter cabinet 33 easily net is cleared up.Certainly opening will be left in the corresponding position on the filter cabinet 33.Adopting plate strainer to enclose as for 24,26 of filtering nets is converted into shape, because of it has certain thickness and intensity, just needn't adds the filtration rack again.
When the product produced of device uses at the scene thus, only need that a certain amount of drag reducing polymerization powder and a certain proportion of suspension base fluid are put into the stirred pot mixing and stirring and get final product.Drag reducing polymerization powder proportion can reach 10～60%.Usually the slurry flow improver injects the scene all has the flow improver storage tank of band whipping appts to link to each other with injection device.Therefore, use this drag reducing polymerization powder scene to need not to increase any equipment, very convenient.Disclosed at " a kind of alpha-olefinic polymer drag reducing suspensions and preparation method thereof " (application number 03109629.8) of application on April 10th, 2003 as for the suspension base fluid, in this just no longer narration.
