Definitions

  • the invention relates to a method for mixing at least two liquid flows with one another in connection with paper and board making, the method comprising: conveying to a inlet chamber included in a mixer at least one first liquid flow substantially in the tangential direction, whereby the first liquid flow resembles a spiral and comprises in the inlet chamber a tangential speed component and a speed component in the direction of the centre axis of the mixer, the method also comprising mixing the first liquid flow with at least one other liquid flow utilizing at least one guide surface in the mixer.
  • the invention also relates to a mixer for mixing flows to be used in connection with paper and board making, the mixer comprising: at least one inlet chamber, which is restricted by at least an outer periphery and end walls, and the inlet chamber is provided with at least one discharge opening in the direction of a centre axis thereof, at least two inlet channels, from which the liquid flows to be mixed can be fed into the mixer, and at least one guide surface for guiding the liquid flow discharged from the inlet chamber, and the mixer further comprising at least one inlet channel arranged on the periphery of the inlet chamber substantially in the tangential direction, whereby a tangential liquid flow can be fed from the inlet channel in order to form a spiral liquid flow in the inlet chamber.
  • US patent 4,861 ,165 discloses a mixer, in which an axial main flow is conveyed through the inlet chamber thereof. A second flow is fed to the main flow from a tangential channel in the inlet chamber that is later mixed with the main flow in the mixing section of the mixer.
  • the mixing section is provided with several consecutive conical spaces, through which the flows must be conveyed in order to mix them with one another.
  • Such a mixer is necessarily relatively long in the axial direction. What also causes a problem to the solution is that it is not suitable to be used in situations where various liquid flows should be mixed with each other.
  • the method according to the invention is characterized by using the mixer, which comprises at least two inlet chambers as considered in the axial direction of the mixer; forming spiral liquid flows in at least two consecutive inlet chambers by feeding at least one liquid flow tangentially into each inlet chamber; guiding the liquid flow formed in the previous inlet chamber to a mixing point, and guiding in the mixing point the spiral liquid flow formed in the latter inlet chamber around the liquid flow.
  • the mixer according to the invention is characterized in that the mixer comprises consecutively as considered in the axial direction at least a first inlet chamber and a second inlet chamber, the inlet chambers being separated from one another with a partition wall, that the periphery of the first inlet chamber and the second inlet chamber comprises at least one tangential inlet channel, whereby a first spiral liquid flow is arranged to be formed in the first inlet chamber and a second spiral liquid flow is arranged to be formed in the second inlet chamber, and that a guide element included in the mixer is arranged to guide the second spiral liquid flow around the first spiral liquid flow.
  • the basic idea of the invention is to form spiral flows in at least two consecutive inlet chambers of the mixer, both flows being provided with a tangential speed component and an axial speed component.
  • the flow formed in the first inlet chamber is conveyed to a mixing point, where the spiral liquid flow formed in the second inlet chamber is conveyed around the flow.
  • the invention provides such an advantage that the structure of the mixer allows mixing in consecutive stages several liquid flows with one another. Regardless thereof the mixer may be relatively short in the axial direction.
  • the liquid flow to be fed into the tangential direction of the inlet chamber is appropriately distributed on the periphery of the inlet chamber and is provided with an adequately sized tangential speed component and axial speed component. Since a relatively significant speed difference can easily be formed for the liquid flows to be mixed with each other, the mixing takes place at the mixing point efficiently. By impact of the speed difference the liquid flow to be mixed penetrates nicely into the flow, with which it is being mixed. Consequently heavy turbulence is formed between the liquid flows to be mixed at the mixing point that efficiently mixes the flows together.
  • An essential idea of an embodiment of the invention is that tangential liquid flows are fed into inlet chambers which are substantially circular in cross section and the flows formed in the inlet chambers are guided to a mixing point as flows which are circular in cross section.
  • the highest tangential speed is achieved on the outer periphery of the circular inlet chamber, a fact that is utilized for increasing the speed difference between the liquid flows to be mixed.
  • the substantially tangential inlet channels are located at different points on the outer periphery of the inlet chamber in two consecutive inlet chambers, in which case the inlet channels of the consecutive inlet chambers are placed at a predetermined angle in relation to one another in the axial direction of the mixer.
  • inlet channels are placed on different sides of the mixer, then more space will be available for leading pipe ducts to the mixer.
  • a further essential idea of an embodiment of the invention is that in two consecutive inlet chambers the flow directions of the tangential inlet channels are placed in relation to one another such that the direction of rotation of the spiral liquid flows in the consecutive inlet chambers is the opposite in respect of one another about the centre axis of the mixer.
  • the flows within each other touch one another in the tangential direction. Touching of the opposite flows causes heavy turbulence and mixing of the flows.
  • At least one of the inlet chambers of the mixer comprises several substantially tangential inlet channels, the flow directions of which are arranged such that a spiral liquid flow is arranged to be formed in the inlet chamber provided with a determined direction of rotation about the centre axis of the mixer. It is thus possible to feed liquid flows to one inlet chamber from various inlet channels.
  • the mixer comprises several consecutively arranged mixing modules.
  • the module structure allows constructing a mixer specifically for each mixing purpose.
  • the mixer may later be changed by adding one or more mixing modules thereto or by removing modules.
  • the module structure also simplifies the structure and production of the mixer.
  • a further essential idea of an embodiment of the invention is that the mixer is structured in modules and comprises at least two chamber modules.

  • the intermediate flange comprises a discharge opening substantially on the centre axis of the mixer.
  • a guide element is placed on the side of one side surface of the intermediate flange, the guide element substantially resembling a truncated circular cone in cross section.
  • the length of the guide element is dimensioned in the axial direction so that it is arranged to separate the spiral flow formed in the previous inlet chamber from the spiral flow formed in the following inlet chamber on the portion of one inlet chamber.
  • the structure formed of separate chamber modules and partition walls allows forming mixers with structures differing from one another.
  • the chamber modules may mutually be substantially alike but they may be arranged in the mixer in different positions in relation to the centre axis or the vertical axis rotated in such a manner that mixers provided with different properties are formed.
  • intermediate flanges including different discharge openings and guide elements may case-specifically be arranged between the chamber modules.
  • An essential idea of an embodiment of the invention is that no axial flow is conveyed to the mixer, instead all liquid flows to be mixed are fed into the inlet chambers substantially in the tangential direction.
  • a further essential idea of an embodiment of the invention is that the mixer is connected to a mixing channel, which conveys the liquid flows mixed with one another by means of the mixer inside a flow channel that is larger in cross section.
  • the area of the outermost end of the mixing channel comprises a mixing part provided with a wavelike shape in cross section that dispenses the liquid flow from the mixing channel to the liquid flow flowing in the flow channel.
