Definitions

  • the invention relates to a new and improved contact device of the character described but which is constructed and functions in a manner which is radically ditl'erent from that of the said patented devices.
  • the basic application of the subject devices is in operations where it is necessary or desirable to bring into intimate contact two fluids, as for example two liquids for the purpose of extracting or separating a component from one of said liquids.
  • the method, construction and operation of the device is based upon certain physical laws and properties of the reactants such as the total or partial immiscibility and varying densities of any two given reactants, and the devices are most advantageously utilized in operations such as purification, chemical treatment, and solvent extraction.
  • the prior devices comprised a sealed cylindrical rotor in which were positioned a plurality of spaced concentric cylindrical bands.
  • the bands were formed with a plurality of perforations or openings.
  • the heavier liquid or other reactant was admitted into the rotor at the center thereof and the lighter liquid was admitted into the rotor under pressure at the periphery thereof.
  • the centrifugal force created thereby cause the heavier liquid to travel through the maze of perforations outwardly toward the periphery of the rotor.
  • the pressurized lighter liquid was forced to travel inwardly toward the center of the rotor.
  • the essential consideration in that device appears to be the supposition that the primary contacting efiect between the two liquids is effected by a jet action of the liquids through the relatively small openings formed in the concentric separator bands.
  • the patented device is based upon the premise that the mixing occurs when the two liquids pass simultaneously through a single small opening. Any surface contact of the liquids in the spaces between the separator bands is described as being an unimportant and even undesirable 3,107,218 Patented Oct. 15, 1963 factor.
  • the patented device is actu-' ally provided with means for reducing or preventing any such surface contact.
  • the patented device employs relatively small openings (0.007 to 0.080 inch) and depends upon relatively high speeds of rotation (4,000 rpm.) to create the said jet action.
  • a further object is to afioi'd a rotating column contact device of the character described in which the openings in the separator bands are substantially larger than heretofore, thus taking full advantage of the gravitational forces set up in the rotating column to insure the greatest amount of surface contact of the liquids between the bands.
  • a related problem resulting from the use of a fixed speed of rotation is related to the fact that the mixing energy required to thoroughly mix any two liquids is directly proportional to the volumetric ratios of the liquids.
  • a much greater amount of mixing energy is required to mix two liquids which are in the volumetric ratio of l to 500 than is required to mix two liquids which are in the ratio of l to 1.
  • the device is often operating at a speed far in excess of that actually required.
  • Still another object therefore is to provide a rotating column contact device of the character described which may be operated at variable speeds so that the greatest control over the mixing of the liquidsis maintained at all times.
  • a related object is to provide a device of the character described in which the speed of rotation may be varied to compensate for variations in throughput so that maximum efficiency is always achieved.
  • Still a further object is to afford a rotating column contact device of the character described which may be operated at the slowest speed consistent with maximum efiiciency, thereby prolonging the life of the device.
  • a related object is to afford a device of the character described having greater diameter (i.e., volume capacity) and number of mixing stages than heretofore possible, and still maintain the operational stresses well within the stress limits of ordinary construction materials.
  • Yet another object therefore is to provide a rotating column contact device of the character described in which the input positions of the liquids may be varied as required, thereby varying the area of settling or clarification.
  • Yet a further object is to afford a rotating column contact device of the character described having removable means for gaining access to the rotor for purposes of cleaning, repair and the like.
  • FIG. 1 is a vertical sectional view of a device embodying the invention, with portions thereof being shown in elevation;
  • FIG. 2 is an end elevational view of the device
  • FIG. 3 is an enlarged fragmentary detail sectional View of the outermost separator bands illustrating the manner in which the liquids flow therethrough and are mixed therebetween;
  • FIG. 4 is an enlarged fragmentary detail sectional view showing a somewhat exaggerated arrangement of the separator bands wherein the spacing therebetween increases as their radii increase.
  • the reference numeral 10 indicates generally the rotating column contact device.
  • the device it? may comprise a pair of standards 12, 12 through which is journaled a rotating shaft 14. Connected to the shaft 14 is a cylindrical rotating column indicated generally by the reference numeral 16.
  • a semi-cylindrical housing such as 18 may be mounted on the standards 12 for'encasing the rotating column 16.
  • the housing 18 may he hingedly connected as at 20 (see H6. 2) and have a handle such as 22 so that ready access may be had to the column 16 for purposes of servicing, maintenance, cleaning and the like.
  • the shaft 14 may be journaled in 'any suitable maner.
  • the standards 12 may include a pair of aligned split rings 24, 24. Seated in each of the split rings 24 may be the outer race of an annular ball bearing 26. Suitable means such as a threaded lock ring 28 and a keying member 34) may be employed for locking the shaft 14 in operational position.
  • Annular cap members 32, 32 may be connected to the standards 12 for encasing the ends of the shaft 14.
  • Each of the cap members 32 may be provided with suitable connecting means such as 34, for connecting to the cap members a pair of conduit sections 36 and 38 whose function will be subsequently described.
  • the column 16 comprises a pair of circular plates 49 and 42 which may be integrally formed with or connected to the shaft 14 in any suitable manner.
  • the shaft 14 is formed with a pair of annular flanges 44, and the plates 4! and 42 are secured thereto by means of the bolts 46.
  • the plates 40 and 42 are connected together adjacent their periphery by a cylindrical shell 48, said shell being secured to said plates by a plurality of bolts such as 50.
  • a plurality of concentric perforated separator bands 52 are fixedly positioned between the plates 40. and 42. Each band is formed with a plurality of perforations such as 53 therethrough. trated, that the bands 52 are arranged so that the spac ing between any pair thereof increases as their radii increase, for reasons which will become apparent as the description proceeds.
  • a plurality of groups of aligned holes' such as 54, 56 and 58
  • rods such as 60, 62 and 64 respectively.
  • Each of the rods 69, 62 and 64 is threaded at its inner end for connection to the shaft 14 in. a manner which will be subsequently described.
  • the shell 48 is also formed with a plurality of threaded openings such as 66, 68 and 7G, each of said threaded openings being aligned respectively with one of said groups of aligned holes 54, 56 and 58.
  • a threaded plug such as 72 is removably positioned in each of said openings 66, 68 and 79.
  • the shaft 14 is centrally bored at both ends thereof to provide a pair of axial openings 74 and 76 which terminate at points near the middle of the shaft, but are spaced apart as shown in FIG. 1 of the drawings.
  • the axial openings 74 and 75 are formed with annular shoulders 78 and 80 respectively to afford enlarged diameter opening portions 82 and 84.
  • a tube 86 Positioned in the opening 74 is a tube 86 which is provided with a plurality of holes 88 formed in the wall of said tube adjacent the inner end thereof.
  • a plurality of bores 90 is drilled radially in the shaft 14 with each of said bores being aligned with a respective hole 38.
  • Each of the bores 96 is complement-arily threaded to removably receive the inner end of one of the rods 60. It will thus be apparent that each of the bores communicates with the opening 74 and a rod 60.
  • a plurality of openings such as 92 is also drilled in the shaft 14 so that the enlarged portion 82 of the axial opening 74 communicates with the center of the interior of the column 16.
  • the conduit section 36 is provided with suitable conduits (not shown) which are aligned respectively with the tube 86 and the enlarged diameter opening 82. Attached to said conduit section 36 and communicating with said conduits is a heavy liquid inlet pipe 94 and a light liquid outlet pipe 96.
  • a tube 98 having a plurality of holes 100 adjacent the inner end thereof is positioned in the opening 76.
  • a plurality of bores 102 is drilled in the shaft 14 with each of said bores being aligned with a respective hole 100.
  • Each of the bores 1112 is complementarily threaded to removably receive one of the rods 62.
  • a plurality of openings such as 104 is also drilled in the shaft .14, and each of said openings 184 is complementarily threaded to removably receive one of the rods 64.
  • the conduit section 3 8 is similar to the conduit section 36 and has connected thereto a light liquid inlet pipe 106 and a heavy liquid outlet pipe 108.
  • each of the rods 64 is hollow throughout substantially its entire length, and has an opening 110 formed therein beyond the outermost separator band 52, or adjacent the periphery of the column 16'.
  • the heavy liquid is withdrawn from the column 16 by flowing through the openings 110 into the rod 64 and out of the heavy liquid outlet pipe 108 along the course already described. Since it is contemplated that the positioning of the openings 119 is always the same, it is apparent that the outlet position of the heavy liquid Within the column 16 is always adjacent the periphery of said column.
  • the light liquid is withdrawn from the center area of the column by flowing directly through the openings 92 and out of the light liquid outlet pipe 96 along the course previously described. Since the radial positioning of the openings 92 is constant, it is thus apparent that the outlet position of the light liquid within the column 16 is also constant.
  • the rods 60 and 62 illustrated are hollow for only a portion of their respective lengths.
  • the rod 612/ has an opening 112 intermediate its length but nearer to the inner end thereof, while the rod 62 has an opening 114 intermediate its length but near the outer end thereof.
  • the rods 69 and 62 may be interchanged with rods which are similar but have their openings i112 and 114 formed in varying positions along the lengths thereof. Since the openings 112 and 114 comprise the inlet openings into the column 16 for the heavy liquid and light liquid respectively, it will thus be apparent that the inlet position of both liquids may be varied at will.
  • one side of the shaft (the right side as viewed in FIG. 1) is provided with a sheave 116 upon which are mounted a plurality of drive belts 118 (see FIG. 2).
  • Each of the drive belts 118 may be connected to a motor of different operational speed (not shown), so that the speed of rotation of the column 16 may be correspondingly controlled for purposes which will be more fully described hereinafter.
  • the operational speed ranges will be between 300 r.p.m. [and 1,000 r.p.m. It should be understood, of course, that instead of the multiple motors and drive belts described, a single drive belt and motor with variable speed control gear box may be employed with equally satisfactory results.
  • the operation of the device may now be described as follows.
  • the inlet openings 112 and 114- are pre-set according to the number of mixing stages and area of clanification required by the particular operation.
  • the heavy liquid and light liquid respectively are introduced into the column 16 through said openings 112 and 114 in the manner described.
  • the shaft 14 and column 16 are ro tated at the'exact predetermined speed suitable for the particular operation.
  • the heavy liquid is forced outwardly by centrifugal force through the perforated bands 52.
  • the pressurized light liquid is forced inwardly through the perforated bands 52.
  • the same is broken up into droplets because of the plurality of perforations 53 in the band.
  • the diameter of the column 16 might be 72 inches, so that the diameter of the outermost band 52 might be 64 inches.
  • the innermost band 52 would have a diameter of about 24 inches. Assuming a speed of rotation of 1,000 r.p.m., we can determine by simple well known calculations that the linear speed of a point on the outermost band 52 will be approximately 17,000 feet per minute. By the same arithmetic calculation, the linear speed of a point on the innermost band 52 will be approximately only 6,300 feet per minute.
  • both liquids travel co-currently or in the same direction as they pass through the column 16. This direction of travel is of course the same as the direction of rotation of the column itself.
  • this liquid is either accelerated or deceleratcd as above described. Since the passage of a liquid from one band 52 to the next takes but a short moment of time, the described acceleration or deceleration thus imparts a violent or jolting action to that liquid.
  • the jolting action is in a direction opposed to the general direction of the liquids travel.
  • the jolting action of the accelerating heavy liquid is in the same direction as the general direction of the liquids travel. There thus occurs a violent cross-collision between the two liquids in the area between any two bands 52.
  • the outermost band 52 has a linear velocity of approximately 17,000 feet per minute. Assuming that the next band 52 is spaced about 2 inches from the outermost band (i.e., a diameter of about 60 inches), the linear velocity of a point on that band is approximately 15,000 feet per minute. it should be ap parent that the greatest amount of acceleration or deceleration will occur between the two bands which are spaced farthest apart. Thus, for example, the acceleration or deceleration between the two innermost bands which may be only about200 inch apart (see FIG.
  • my device actually comprises a rotating column in which centrifugal force is used to impart mixing energy tothe liquids.
  • the perforations in the bands 52 are considerably larger than heretofore, the same ranging in diameter or size from 7 (.094) inch to /2 (.500) inch.
  • the area of the perforations iu' the bands should be approximately to 11 times the area of the admission openings of the liquids.
  • the innermost band may have a perforation area of about 5 times the area of theliquid admission openings, while the perforations of the outermost band may be about ll times the area of the liquid admission openings.
  • the device is designed to most efiiciently utilize the known applicable physical laws.
  • the space between the separator bands increases as their radii increase.
  • the input positions of the two liquids may be readily varied to provide any desired area of clarification.
  • the device employs variable speed drive means so that complete control over the mixing of the liquid may be maintained at all times.
  • the variable speed also permits compensation for less than maximum throughput,
  • a rotating column contact device for effecting intimate contact between relatively immiscible liquids of different densities comprising; a rotor, means for supplying heavier liquid to and means for removing lighter liquid from the interior of said rotor adjacent the axis thereof, means for forcing lighter liquid into and means for discharging heavier liquid from the interior of said rotor adjacent the periphery thereof, a plurality of spaced concentric separator bands positioned in said rotor, each of said bands being formed with a plurality of openings therethrough, the spacing between adjacent bands increasing as their -radii increase.
  • said first means and third means include a heavier liquid inlet hole and lighter liquid inlet hole respectively, and means for readily changing the position of said inlet holes relative to the axis and periphery of said rotor.
  • said last-mentioned means includes portions of said separator bands having a plurality of groups of aligned holes formed therein and portions of the periphereal shell of said rotor having a plurality of service openings formed therein one in align ment with each of said groups of aligned holes, a service plug removably closing each of said service openings, and a plurality of rods each of which is removably positionable in one of said groups of aligned holes, said inlet holes being formed in said rods at varying positions relative their length.
