Referring now to the drawings, this invention comprises of a structure having a base 11, mounting rigidly thereon a cylinder 12, which is closed on the other end by a cover 14 provided with discharge openings 15, and secured with screws 64, which forms chamber A. A secondary inside shorter cylinder 16 is mounted and secured on base 11 and forms the heating and oxidizing chamber B. The space formed by cylinder 12, cylinder 16 and rigidly secured space ring 19 acts as the impure uid channel C, which has a discharge connection 24. Also rigidly supported on the periphery of base 11 is a heat guard cylinder 20, which with cylinder 12 and rigidly secured perforated spacer 22 forms the preheating chamber D.
The rotative hollow shaft 13 is mounted on bearings 26 and 26 to base 11 and cover 14, these shaft bearings are encased by retainers 27 and 27' and secured by screws 24 and 24. The hollow shaft with aid of spacers or equivalent and fasteners accurately positions and rigidly supports the turbine 30, heating elements 33, the catalytic reacting type filter element 48, and liltering elements 58, 66, 74, and 85, as well as deflectors 54 and 90, pulley 25 and the rotative fluid carrying tube 92.
Lower part of chamber B contains an automatic adjustable temperature reactor assembly 36, and controller assembly 35 to operate inlet valve assembly 34, which admits predetermined Volumes of hot air from shielded preheat chamber D interrupted or continuously as the correct temperature is attained. Temperature'reactor and controller assembly 105 makes contact for the electric current which passes through insulated mounting screws and 100', and insulated tension springs 99 and 99 to insulated carbon brushes 98 and 98' which transfer to conductor rings 44 and 44', details of insulations not shown. Both temperature reactor and controller assemblies 35, 36, and are shown diagrammatically, the electric power sources for same are not shown. Check valve assembly 104 prevents back flow into the stack assembly 28.
The gases E enter through inlet 28 into chamber Bl These products are commercially available. One end of heating element 40 is connected through an electrical conductor wire 42 to the electrical conductor ring 44, the other end of the heating element 40 connects to the electrical conductor wire 42", which connects to the electriacl condutor ring 44'; all of the previous are enclosed, shielded, insulated and supported in insulator 41. The entire heating coil assembly 33 is located and secured rigidly by set screw 45 on shaft 13 at its proper position.
The catalytic reacting type filter element 48 consist of platinum or platinum group material coated metal wires or vanes 49, which are firmly clamped between rings 50 and50. by rivets 51. Spacer 46 locatesV catalytic assembly in` proper position, and the latter is securely clampedv down by right angle flange of ring 50 which is` held to hollow shaft 1-3 with set screw 52.
The annular partially deflected deflector 54, feeds the impurities filled liquid H to the off flow passage C, as well as acting the structure for the integral shaft mounting flange 54', which is secured to the shaft with set screw 55, for the passage of the impure fiuid elements E openings 56 are provided in the right angle part to fiangek S4 of dcfiector 54.
Filter assembly 58 consist of corrosion resistant somewhat round wires 59 clamped straight or at a tangent between rings() and 60'; which are held firmly together by rivets 61.
Stationary reversing flow defiecting vanes 62 and 62a which are secured to reversing fiow angle type vertical defiectors 63, which are held in position by screws 64, and supported by peripheral ring 65.
Filter assembly 66 consist of annular metal blanks with partially `sheared vanes 67 and 67. Vanes 67 are offset from vanes 67 at junction 68 to permit the passage of fluids. The multiple units vane 67 and 67 are held apart by spacers 69, and held together by rings 70 and 70' which are tied together by rivets 71. Vane blades 67 and 67 are coated by an impurities absorbing material such as charcoal 72 or the like, which is cemented to the surface by a moisture proof heat resisting cement; one of which is Minnesota Mining Compound #EC-194.
Compartment 74 consist of an annular, in essential areas, perforated cover 75 which is mounted with upward turned fiange 76 and secured by a set screw 77 to shaft 13. The outer circumferential downward turned fiange 78 retains the conical screens 79 and 79a which are secured by mounting screws 89. The inside wall of assembly 7'4 is formed by a total area perforated spacer 81, which is rigidlyv secured to totally perforated annular lower base 82. 'Ihe annulary base 82 has at its outer circumference an obtuse angle iiange 83 which in turn mounts rigidly screens 79 and 79a with rivets 84. Screens 79 and '79a formy a cone shaped overhangI 85. The entire screen surface. is coated with an impurity absorbing material such as activated charcoal '72 which is retained by moisture and heat proof bonding cement to the wires. Overhang S acts as a cone type filtering screen. The entire compartment 74 is filled with an impurity absorbing material 86 such as charcoal or the like reacting compounds, chemicals or materials.
Filter assemblies 5S, 66 and 74 are held tightly in proper position by screw 77 on one side, and screw 88 on the opposite side of the assemblies on shaft 13. Spacer 89 properly aligns this assembly. Screw 88 primarily secures flanged rim 90', which is a part of the annular defiector 9i) which prevents the fluid G from entering chamber B.
The liquid supply tube 92 is rotative supported by spacers 93 and 94 to hollow shaft 13 and the ultimate end is open. The opposite end connects via rotative couplings to a mechanism for automatic or manual adjustable valve control, which in turn connects to a pressure line or storage tank, neither of which are shown. Spacer 93 rigidly secured to tube 92, and contains seal 93./ which separate the uid ef the area, which is served by the outer tube 13 from the one that is served by the inner tube 92. Gpenings 94 in spacer 94 permit passage of fiuid G through perforations 95 for continuously fiushing of filter element 58. The rotative mounted hollow shaft 13 is closed on the ultimate end and has perforations 96, which supplies fluid intermittently to assemblies 66, and 74. The other lencl of hollow shaft 13 is connected to an automatic or manually operated valve mechanism for regulating,V timing, the volume.l of fluid, which is supplied through a flexible rotative coupling from a pressure line orl tanky not shown. The arrangements of continuously or intermittent supply of fluid can be changed as the designs or requirements may be.
E, or arrows with single dot indicate lighter fluids to be cleaned or separated.
F, or arrows with two dots indicate cleaned or separated lighter liuids.
G, or arrows with three dots indicate heavier somewhat clean fluid.
H, or arrows with four dots indicate fluid loaded withl impurities or elements removed from the lighter: uid.
The accumulated gases,v odors, fumes, and other substances are gathered by the accumulator stack 28 and discharged into the lower chamber B. While passing through this. space B the temperature reactor 36 will react at the predetermined temperature and engage the valve controller 35 and add fresh heated air from heat shield chamber D through valve assembly 34. Also if' necessary in this chamber the temperature reactor 1051 will engage the temperature controller and charge electricity to the heating assembly 40. i
From chamber B` a turbine fan 30 will accelerate the lighter fiu-id E and create a low pressure area at the lower section of compartment B to prevent back pressure throughthe accumulator stack 2-8 to the various furnaces, engines, pots and the like. Next the gases enterV the heating unit 40 Where the temperature is increased if necessary. The minimum temperature necessary of approximate 500 degrees will oxidize the hydro-carbone in the next in line element which isthe catalytic filter 48. With the hydro carbons minimized, the next process is to filter out the other impurities. The wire brush type elements 58 with the by capillary action or otherwise liquid coatedwires or vanes in rapid rotation make an enlarged surface area of moisture exposed tothe impure elements, and make inthis way an extremely efficient operation, in the ratio of gases processed for the volume of liquid needed'. Due to the centrifugal forces, and aided by addition of the heavier liquid, the filtering elementsV are self cleaning.- p To minimize the inclination of the gases to follow therotative movement of the filtering elements, reversing flowq defiectors 62, 62a and 63 areprovided at intervals, which add in this manner to increase the multiple contacts of" the rapid rotating filter elements to the retarded' or reverse ow impure lighter fluid.
Despite the effort of increasing the contacts betweenv the minute impure particles and the filtering media, natural phenomena have to be engaged in an efficient practical manner. Materials such as charcoal, or other equal characteristic4 materials, compounds or chemicals which have an afiinity for the removal of impurities or predeterminedelements from the gases or fluid as well as react to cleansing fiuid for the removal of same, have to or discharged to a container which is not shown. -f
11.1 Caso of higher temperature in the upper part of chamber A solid larger particles such as charcoal or the like purpose serving elements may be dispersed and held between multiple screens, similar to assembly 85. Under the same conditions units like assembly 66 may operate without the absorbing. coating and serve the same purpose as assembly 58.
With the aid of changes in fluids, timing, ow patterns, and electrical charges, various units of this apparatus can be applied to other uses, than those described, such as filtering, compounding or decompounding products of oil, gasolines or other fluid like chemicals, gases or other elements.
