SEPARATING METHOD AND SEPARATING DEVICE

Japanese Patent JPH1130482

A

PROBLEM TO BE SOLVED: To suppress discharge of solvent steam to the atmosphere and to prevent mixture of deteriorated rubber by a method wherein particles and steam discharged from a drier are inputted in a closed steam flow and conveyed by a steam flow and after particles are separated, a steam flow is circulated to the outlet of the drier, and the pressure of a closed steam flow circulation system is regulated. SOLUTION: A rubber material and steam injected in an air flow drier 21 are conveyed by a superheated steam flow and to a solid gas separator 22. The rubber material is collected, and the rubber material and gas are separated away from each other. Gas (steam, HC, and solvent steam) separated by the solid air separator 22 is washed by a steam washer 23 and boosted by a blower 24. The gas is heated by a steam heater 25 and re-circulated to the air flow drier 21. A pressure in a circulation box 28 containing the air flow drier 21 is normally detected by a pressure sensor 31 and fed to a controller 32. The controller 32 monitors a pressure in a circulation passage 28 and controls such that a valve 33 is opened each time the pressure exceeds some threshold.
