Definitions

  • the invention relates to a separator for separating immiscible liquids which contain solids, which is specifically heavier than the heavier liquids, with a conical drum in which separation aids are arranged and project into the inlet pipe, gripper and outlet pipe.
  • Liquids from chemical processes usually contain solid impurities, e.g. Rust particles, insoluble salt and the like. Their concentration is on the order of fractions of a thousand to percent. These solids fractions are very often completely irrelevant for the further production process due to their low concentration and can then usually remain in the process without interfering in the slightest with the further process flow.
  • solid impurities e.g. Rust particles, insoluble salt and the like.
  • Their concentration is on the order of fractions of a thousand to percent.
  • These solids fractions are very often completely irrelevant for the further production process due to their low concentration and can then usually remain in the process without interfering in the slightest with the further process flow.
  • the separator drum is filled with these solids more or less quickly, so that it is no longer possible to separate the liquids. The result is that the separators often have to be cleaned. This cleaning requires a lot of manual work and leads to a considerable reduction in the capacity of the respective separator.
  • Self-cleaning separators are known whose drums have slots or nozzles that are opened manually or automatically as soon as the sludge space has filled up.
  • Another disadvantage is that the known separators fail when the melting point of one or both components is a certain amount above room temperature. While these components can be handled very advantageously in the liquid phase at other physical or physico-chemical process stages by melting, there is no possibility of separating the components in the liquid phase with the aid of separators, since the known separators are in principle due to their construction are not heatable.
  • the object of the present invention is therefore to provide a separator with which two immiscible liquids containing solid which is specifically heavier than the heavier of the two liquids can be separated quantitatively. At the same time, there should be the possibility of heating or cooling the separation space.
  • a separator which is characterized in that the drum is arranged within a static pressure chamber and has openings on the equator which open into the static pressure chamber, and the static pressure chamber is provided with an adjustable removal device.
  • the drum is divided into several double-conical spaces, at the top of which the openings are arranged through which the heavy phase containing the solid exits into the static pressure chamber.
  • the slope of the walls of the conical drum or of the double-conical spaces is expediently chosen to be greater than or equal to the angle of repose of the solid to be separated off.
  • devices for taking the heavy phase such as ribs and the like, can be arranged on the outside of the drum wall.
  • the static pressure chamber can be surface-coated on the inside, for example, ' highly polished.
  • the static pressure chamber is equipped with a gripper or a weir as a removal device for the joint discharge of heavy phase and solid matter.
  • Weir or gripper are arranged and dimensioned with respect to their diameter so that the separation zone of the two phases lies at a convenient location within the rotating drum.
  • openings on the equator of the conical pressure chamber can serve as a removal device.
  • the openings can be provided with valves which, if desired, are controlled by a measuring probe which is arranged in the pressure chamber at the desired height of the mixture of heavy phase and solid.
  • the static pressure chamber can be double-walled for the purpose of indirect cooling or heating of the separator contents. When using a conical static pressure chamber, the slope of the walls should again be chosen to be greater than or equal to the angle of repose of the solid to be separated.
  • the inlet pipe 1 for the mixture projects into the rotating conical drum 7 of the separator, which is provided with separation aids, the guide plate 5 for the incoming mixture and the separation plates 6.
  • the outlet pipe 2 for the light phase is arranged concentrically with the inlet pipe 1 and connected to the same. Inlet pipe 1 and outlet pipe 2 are in turn connected to the static pressure chamber 11.
  • the gripper 4 is arranged on the end of the drain pipe 2 projecting into the drum.
  • the guide plate 5, via which the mixture to be separated is distributed into the drum, is connected to the drum 7 via webs 14.
  • the separating plate 6, truncated cones, are stacked concentrically around the guide plate 5 on the same.
  • the diameter of the gripper 4 must be smaller than the smallest diameter of the separation plate 6.
  • the guide plate 5 and the separation plate 6 are provided with recesses 15. At the level of these recesses there should be approximately the separation zone in which the mixture is separated into light liquid (phase) and heavy liquid (phase), which may also contain solids.
  • the drum 7 is connected to a drive shaft 12. In order to avoid dead spaces for the solid, the drum 7 can be double conical be trained.
  • the slopes ⁇ and ⁇ of the drum walls should be chosen to be greater than or equal to the slope angle of the solid. Under slope angle the ratio of B öschungsnch shall be understood to embankment width.
  • the drum 7 is provided with openings 13 which open into the static pressure chamber 11. Devices, for example ribs 8, can be arranged on the surface of the drum 7 to take the heavy phase with them.
  • the pressure chamber 11 can also be conical. It is equipped with a removal device for the heavy phase.
  • the removal device can be a weir 3, a gripper 9 or, if the static pressure chamber 11 is conical, consist of several openings 10 which are arranged on the equator of the conical static pressure chamber 11.
  • the openings 10 can be provided with valves 16.
  • the valves 16 are equipped with a level indicator 17, e.g. a measuring probe.
  • the diameter of the weir 3 or the gripper 9 must be larger than the diameter of the gripper 4.
  • the position of the separation zone in the drum also depends on the diameter of the weir 3 or the gripper 9.
  • the slope ⁇ of the walls is to be chosen to be greater than or equal to the slope angle of the solid.
  • the heavy phase collects in a trap chamber 19 and then runs off via pipe 18.
  • the heavy phase runs through outlet 20, which is arranged concentrically with the inlet pipe 1.
  • the static pressure chamber 11 can be provided with a double jacket 21.
