DEVICE FOR HEATING BY STEAM AND COOLING BY VAPORIZATION

摘要

PURPOSE: To obtain a device for heating by steam and cooling by vaporization by which a material to be heated is heated by steam without time lag and with good temp. accuracy and also the material above is cooled by vaporization. ;CONSTITUTION: A steam feeding pipe 17 for feeding steam is connected to a jacket part 16 of a reaction kettle 15. A line branches off from the steam feeding pipe 17 and is connected to a high pressure operation fluid introducing port 38 of a condensate recovery device 20. The steam feeding pipe 17 is connected to a nozzle 18 through pressure regulating valves 21, 42. A suction chamber 44 is formed on the outer periphery of the nozzle 18. The suction chamber 44 is provided with two paths 45, 46. The path 45 is connected to the jacket part 16. A valve means 47 is connected to the path 45. A cooling liquid feeding pipe 13 is connected to the jacket part 16 through a valve means 14.;COPYRIGHT: (C)1995,JPO
