WASTE HEAT WITHDRAWAL DEVICE FOR VAPOUR COMPRESSORS

摘要

A waste heat withdrawal device includes: a compression part which is configured to include four or more compressors, and compresses vapor discharged from a plant at high temperature and high pressure in multi stages and then returns the compressed vapor to the plant; a low pressure condensate tank which stores low pressure condensate discharged between a first compressor and a second compressor; a middle pressure condensate tank which stores middle pressure condensate discharged between the second compressor and a third compressor; a high pressure condensate tank which stores high pressure condensate discharged between the third compressor and a fourth compressor; and a vortex tube which is delivered with the low pressure condensate provided from the low pressure condensate tank, the middle pressure condensate provided from the middle pressure condensate tank and the high pressure condensate provided from the high pressure condensate tank, separates the condensates into high temperature vapor and low temperature water, returns the high temperature vapor to the plant and discharges the low temperature water to the outside. The waste heat withdrawal device of the present invention can maximize energy consumption efficiency.
