Definitions

  • the present invention relates to a heat exchanger apparatus, particularly suitable for being used for the treatment of viscous liquids such as, for example, solutions of polymers contained in certain hydrocarbons.
  • the object of the present invention is the production of a heat exchanger device particularly suitable for treating viscous liquids, and by which obtaining very high heat exchange coefficients, even thanks to the remarkable extension given to the surfaces in contact with the viscous liquid.
  • This is achieved by the heat exchanger device, object of this invention, by placing inside and coaxially with a hollow cylindrical trunk body, a rotor and a stator provided with a cooling or heating jacket. , between which can rotate freely, around its same longitudinal axis of symmetry, a chassis with scrapers for cleaning the interior surfaces of the rotor and exterior of the stator.
  • the chassis wall serves as a dividing wall between the flow of viscous liquid, which flows between the rotor and the stator, and the coolant (heat conductor) which flows between the wall of the device body and the rotor.
  • the heat exchanger comprises a cylindrical trunk body 1, joined to a structure of fixed support (which is not shown in the figure), where a rotor 2 and a stator 3 are placed coaxially; the latter is equipped with a jacket, in which, in the case of the use of liquid refrigerant (heat conductor) it is necessary to install a partition, otherwise a spiroidal fin 4.
  • the rotor 2 is supported by bearings, 5 (which can be ball or roller bearings, or more simply bronze bearings) and can be made to rotate around its axis of symmetry by a pulley 6.
  • bearings, 5 which can be ball or roller bearings, or more simply bronze bearings
  • Chambers 7 and 8 equipped with holding elements, are used for sending and evacuating viscous liquid from the device.
  • scrapers 9 are used, fixed on chassis 10 supported empty by the hollow spindle 12 and by the shaft 13 of the stator 3, with the bearings 11.
  • the refrigerant (heat conductor) is sent and discharged from the annular space between the body 1 and the rotor 2, take place respectively through the troughs 14 and 15; while sending and the evacuation of the refrigerant (heat conductor) from the jacket of the stator 3 takes place respectively through the troughs 16 and 17.
  • the viscous liquid which arrives at the apparatus through the chute 20 of the chamber 7 without interruption, flows into the peripheral space between the rotor 2 and the stator 3, and it exits the apparatus through the chute 21 from room 8.
  • the refrigerant (heat conductor) must be pumped into the device against the flow of viscous liquid, divided into two flows: one which enters through the chute 14, it flows in the peripheral space between the body 1 and the rotor 2, it leaves the device through the chute 15; the other through the chute 16 and the hollow spindle 13 and the chute 17.
  • the chassis 10 Because of the resistance of the scrapers 9, which clean the surface of the stator 3, the chassis 10, with these scrapers, rotate at a lower speed than that of rotation of the rotor 2.
