Definitions

  • the invention relates to the use of a static mixing element for Homogenizing and dispersing liquid, gaseous or powdered Media for producing a drilling fluid.
  • a Liquid with a powdery substance or a liquid or a Suspension, if necessary to facilitate and improve the drilling process for example, a bentonite-water suspension, as a drilling or rinsing fluid should be used.
  • a bentonite-water suspension keeps the cuttings in suspension, Lubricates the pipe string when it is pulled in and protects it after a certain curing phase against the surrounding soil.
  • To the variation of Property of the suspension may contain additives such as soda ash or polymers.
  • drilling fluids are stored in a separate storage tank by an agitator working in this tank, ie a dynamic one Mixer, or mixed by a fast running pump.
  • DE-PS687 926 shows the use of a static mixer which is based on perforated dividing walls, which run transversely to the flow direction, for the production of physical foam for fire fighting purposes.
  • US 4,313,680 A shows a static mixer with perpendicular to the flow direction arranged deflecting elements for mixing of different media with very short reaction time.
  • Japanese Laid-Open Patent 61-242 624 discloses an apparatus for producing an emulsion Water and oil, which has a static mixer.
  • US 4 514 095 A discloses a static mixer for fluids comprising a Mixing effect by diverting part streams from a core area into one Edge area and back reached.
  • US 4,370,062 A describes a mixing gun for mixing two-component adhesives, at the top of a static mixer with baffles sitting.
  • US 4 412 582 A describes a vertical arrangement of baffles in a heat exchanger through which, to improve heat transfer, the flowing fluid is added to turbulence.
  • US 4 854 721 A discloses a device for mixing drinks Concentrate and water, also perpendicular to the main flow direction having arranged deflecting plates.
  • US 5 522 661 A discloses a static mixer which is particularly applicable simple and inexpensive way to produce.
  • the deflection surfaces are arranged at an angle of 45 ° to the flow direction of the fluid.
  • DE 36 18 062 A1 describes a device for mixing pasty or gelatinous components, being from a central in one Mixing tube arranged axis extending in the radial direction guide walls, widening in the radial direction and at an angle to the flow direction of the fluid are arranged.
  • the adjacent guide walls of the a wing ring forming mixing insert overlap each other and have passages.
  • a drilling fluid is the addition medium, such as bentonite, the Water in powder form before or after one of the drilling fluid to the drilling rig forwarded to transporting hydraulic pump. Behind the pump can one be arranged static mixing section, which is the additive and the water homogenized.
  • a static mixer as he for example from "weighing + dosing" 3/1997 Page 23 to 26 is usually made of a plurality of diverse, successively connected individual mixing elements, with Help an adapter can be used in a supply or discharge system can.
  • Each of these mixing elements has one or more deflection surfaces which, if appropriate, pass through one or more passages become.
  • the one another either within a mixing element or in Downstream mixing elements following deflection surfaces are always there at small angles inclined to each other and also have regard to the Flow direction of the medium flowing in the conduit coinciding a small; from 90 ° different inclination angle.
  • the deflection surfaces facing each other and to the flow direction at a particular axis angle produce a forced guidance of the flow, so that it repeatedly rotates its flow direction.
  • the possibly passing through the deflection passages also extend at an angle to each other and to the deflection surfaces, so that both a division of the current and a multiple change of the flow direction takes place.
  • the individual streams are brought together again. This multiple splitting, diverting and merging of the media causes their homogenization or dispersion.
  • the geometry of the deflection surfaces and through holes as well their arrangement relative to each other and to the flow direction such be arranged to ensure as possible a lack of dead zones can be, because they prevent a homogeneous mixing.
  • a significant disadvantage of the known static mixer is that the in Complex geometry manufactured mixing elements in complex production processes have to be produced, which costs a considerable amount of time and money cause. Especially the sometimes massive design of the mixer with differently aligned passages makes a high cost of materials required.
  • the invention is therefore based on the object, a static mixer finding an efficient homogenizing and dispersing various Media for producing a drilling fluid with structurally simple It also makes mixing elements easy to manufacture and simple to be cleaned.
  • the object is achieved by the use of a mixing element with at least one deflection surface which is at an angle of 70 to 110 ° to the Main flow direction of the media aligned in the flowed line is for mixing and producing a drilling fluid, in particular a Bentonite-water suspension.
  • the invention is based on the idea that during the impact of the Media on the only slightly inclined to the flow direction deflection and the flow around their edges shear forces that cause the swirling and Mix the media.
  • the particular advantage of the mixing element according to the invention lies in its simple construction, which is manufactured inexpensively and without special machinery can be.
  • Another advantage is that due to the special orientation of the Deflection area no acute angle between the area and the surrounding Housing or the wall are present. This is the cleaning of the mixing element considerably relieved.
  • the deflection surface is in one Angle of 90 ° to the flow direction of the media arranged, i. she stands perpendicular to the flow direction.
  • the shape of the Cross-section of the deflection surface substantially to the cross-sectional contour of flowed through line correspond.
  • its diameter but smaller than that of the line, so that between the line and the Deflection at least one passage for the deflected from the deflection Medium arises.
  • the deflection surface can flow through fastening means directly to the flow Line or on a housing of a line to be used in the line Attached mixing element.
  • the housing of the mixing element can be designed in such a way that lying in the flow direction behind the deflection side surfaces of the housing can be used to guide the medium.
  • they can run in a funnel shape to become one on one Deflection of a downstream or in the same mixing system located Conveying leading constricting passage opening.
  • the deflection surface with Be provided openings that a division of the striking on the surface Enable mediums. This can improve the homogenization be reached, but without significantly cleaning the system is difficult.
  • the individual mixing elements can in a mixed system in a variety be switched one behind the other. It may also be advantageous, mixing elements parallel next to each other when e.g. the flow rate to be increased to media.
  • the mixing element used in the invention can for homogenizing and Mixing of gases, liquids, suspensions or dispersions used become. It can thus be used in a variety of different processes and Devices, e.g. from the fields of chemical or process engineering as well as in the plastics industry, water treatment or in the food industry Find use.
  • drilling fluids e.g. Bentonite-water suspensions
  • Bentonite-water suspensions be used, for example, for horizontal or Vertical holes are needed.
  • a single element 1 of the mixing system consists of a housing 2 with two Sloping surfaces 3 and 4, which are funnel-shaped to a through hole 5 narrow. They allow the passage of the arrow in the direction of the inlet opening 6 in the mixing system inflowing medium.
