Process for recovery of heat energy contained in vapor, for drying device in industrial facility, involves compressing fatal vapor to raise condensation temperature of vapor, and recovering energy by partly using energy of compressed vapor

摘要

The process involves removing fatal vapor by pumping out the vapor by an evaporator (10), and compressing the fatal vapor to raise the condensation temperature of the vapor by using an industrial method. Energy is recovered by partly using the energy of the compressed vapor by another industrial method, where the fatal vapor is at a temperature between 50 and 100 degrees Celsius such as 65 degrees Celsius, and the compressed vapor is at a temperature between 70 and 140 degrees Celsius such as 80 degrees Celsius. An independent claim is also included for an installation for recovery of heat energy contained in the vapor.
