Definitions

  • the invention relates to a modular fluid conduit system for passing a crystallizing, heat-sensitive working fluid such as a synthetic polymer or a polymer solution, a cellulose derivative, a solution of cellulose, water and amine oxide, and mixtures thereof, with at least two series-connectable fluid line pieces, each one in operation Having flowed through the working fluid working fluid line area.
  • a crystallizing, heat-sensitive working fluid such as a synthetic polymer or a polymer solution, a cellulose derivative, a solution of cellulose, water and amine oxide, and mixtures thereof
  • Such fluid line pieces are known as simple pipelines and are conventionally used in spinning plants in which the working fluid is spun as a molding composition into shaped bodies. Through the fluid line piece, the working fluid from a reaction vessel in which it is mixed together, usually transported to a spinneret, where it is spun.
  • the working fluids used are heat-sensitive and prone to a spontaneous exothermic reaction when a certain maximum temperature is exceeded in the fluid conduit, or when the working fluid is stored too long below that maximum temperature.
  • the working fluids contemplated by the present invention generally have a very high temperature-dependent viscosity.
  • the viscosity decreases with increasing temperature and increased shear rate.
  • a molding composition consisting of a spinning solution containing cellulose, water and a tertiary amine oxide, for example N-methylmorpholine N-oxide (NMMO) and stabilizers for thermal stabilization of the cellulose and the solvent and optionally other additives such
  • NMMO N-methylmorpholine N-oxide
  • stabilizers for thermal stabilization of the cellulose and the solvent and optionally other additives
  • the fluid line piece For the transport of the working fluid, the fluid line piece must be heated on the one hand, so that the viscosity of the working fluid decreases and the working fluid can be promoted with low losses through the fluid line piece. On the other hand, the temperature must not be too high to avoid decomposition and a spontaneous exothermic reaction of the working fluid. Finally, as uniform as possible a velocity profile should form over the flow cross section of the fluid line piece through which the working fluid flows in order to ensure a uniform flow through the fluid line section.
  • EP 0 668 941 B1 proposes controlling the temperature in the middle of the tube and / or on the inner wall of a fluid line piece according to the formulas given there.
  • a cooling medium is passed through a cooling jacket surrounding the working fluid line region.
  • the cooling medium dissipates the heat from possibly occurring exothermic reactions from the working fluid and cools the outer region of the fluid flow.
  • DE 35 32 979 A1 an internal heat tracing for pipes is known.
  • a flow-around tubular hollow body is arranged in a substantially tubular transport and / or delivery line, in particular made of glass.
  • the tubular hollow body is flexible and has a thin wall, so that it gives way to any turbulence due to oscillating movements.
  • the device of DE 35 32 979 A1 is suitable, for example, for plant for sulfochlorination, where the subsidized by the transport and / or delivery line substances should be observed.
  • the fluid conduit system as proposed in EP 0 668 941 B1, has the disadvantage that still a poor efficiency in the flow through the working fluid is achieved, and that only inaccurately the temperature-dependent properties of the working fluid can be influenced.
  • the invention is therefore an object of the invention to provide a fluid line piece, which has an improved efficiency in the flow of the working fluid and allows a more direct influence on the temperature-dependent properties of the working fluid.
  • this object is achieved for a modular fluid line system of the type mentioned above in that the working fluid line region has a substantially annular flow cross section and in the middle of the fluid line piece instead of the core flow of the working fluid, an inner Temper michsvorraum to control the temperature of the working fluid within the Working fluid line region is arranged and is flowed through during operation of a Temper michsfluid, and provided between the at least two fluid line pieces supply module is provided through which during operation Temper michsfluid from outside the tempering device can be fed.
  • the temperature of the outer fluid can thus be influenced very well over the entire flow cross-section.
  • the tempering device occupies the position of the core flow and allows control of the temperature of the working fluid from within the flow. As a result, the working fluid and thus the temperature-dependent properties can be control the working fluid more accurately, the flow losses can be lowered. It also eliminates the need to measure the temperature of the core flow, which is possible only very inaccurate and indirect and with great effort.
  • the internal area of the working fluid can thus be directly influenced in its temperature by the tempering device according to the invention flowing around the working fluid ,
  • the thickness of the flow cross section to be tempered is reduced by the arrangement of the temperature control device instead of the core flow of the working fluid and the consequent annular working fluid conduit region.
  • the thickness of the layer to be tempered corresponds to that of the inner diameter of the working fluid conduit region .
  • the layer thickness of the working fluid to be tempered only corresponds to the wall thickness of the annular flow cross section. The reduced layer thickness reduces the time constants for the heat transfer.
  • the temperature control device can serve both for cooling and for heating the working fluid, depending on whether the temperature of the temperature control device is higher or lower than the temperature of the working fluid.
  • the temperature of the temperature control device can also be controlled such that certain sections of the temperature control device act as cooling sections and other sections as heating sections.
  • the reference temperature of the working fluid used here is the temperature of the working fluid averaged over the flow cross section of the working fluid conduit region.
  • the temperature control device is designed as an inner tube arranged coaxially with the working fluid line region, through which a temperature control fluid flows.
  • the cooling or heating of the working fluid through the tempering fluid flowing through the tempering device can take place in countercurrent or direct current.
  • DC the flow directions of the working fluid and Temper michsfluid are substantially rectified.
  • countercurrent flow directions of working fluid and Temper michsfluid are essentially in opposite directions.

  • a tempering fluid By means of a tempering fluid, it is possible, for example, to achieve a more uniform heat transfer without large local temperature differences compared to an electrical heating.
  • Temper michad in Temper michsmantelabites has a temperature independently controlled by Temper michsfluid in the temperature control. Regardless of the Temper michsvorraum the Temper michsmantelabsacrificing can be used for cooling or heating in cocurrent or countercurrent.

  • the spacers may have a substantially streamlined cross-section.
  • the heat transfer surface can be increased again, even if the spacer is flowed through by the Temper michsfluid. As a result, it is also possible to act directly on the working fluid which does not come into direct contact with the tempering device or the temperature control jacket section. At the same time a structurally simple way of supplying the tempering with Temper michsfluid is possible by this solution.
