DEVICE FOR COMPRESSING AND DRYING GAS

摘要

Device for compressing and drying gas, and this device (25) contains a multistage compressor with a low pressure stage (30), a high pressure stage (36) and a pressure pipe (39) and an adsorption dryer (27) with a drying zone (41) and a regeneration zone (40), whereby an intercooler (34) is placed between the low pressure stage (30) and high pressure stage (36), and whereby the device (25) is further provided with a heat exchanger (1) with a main compartment (7) with an inlet part (9) and an outlet part (10) for a first primary fluid, and whereby the ends of the tubes (13) of the heat exchanger (1) are connected to a separate inlet compartment (14 and 16) and outlet compartment (15 and 17) for each series of tubes (11 and 12); and whereby a first aforementioned series (11) of tubes forms a cooling circuit of the aforementioned intercooler (34) in order to heat up gas from the high pressure stage (36) for the regeneration of the adsorption dryer (27).
