Abstract:
A compressor installation comprising a water-injection cooled compressor (12) having its pressure outlet connected by a connection duct (18) to a settling vessel (20) for separating the injected cooling water (25), the settling vessel (20) being a pressure container connected to the outlet of the compressor (12) in a pressure-tight manner, the compressor installation further comprising a cooling water conduit (28) leading from the settling vessel (20) to the compressor (12), a cooling means (32) arranged in the flow path of the cooling water (25) between the settling vessel (20) and the compressor (12), oil-free cooling water (25) circulating in the circulation circuit (26) formed by the compressor (12), the connection duct (18), the settling vessel (20), the cooling means (32) and the cooling conduit (28), the cooling water being urged towards the cooling means (32) by the pressure prevailing in the settling vessel (20), a water treatment device (31) for preventing mineral deposits is arranged in the circulation circuit (26), the cooling water contained in the circulation circuit being free of additives, means (70) for adjustably controlling the injection of cooling water into the compressor (12) to effect substantially isothermal compression, and the water treatment device (31) being a polarization means for electrically charging foreign matter transported in the cooling water (25).
