Abstract

The invention provides a centrifugal gas compressor desuperheater with a center nozzle structure. A centrifugal gas compressor comprises a compressor shell; and the compressor shell comprises an intake port opened to the direction of a compressor rotating shaft, and an intake channel connected with the intake port. The centrifugal gas compressor further comprises a compressor impeller; the compressor impeller is rotationally supported in the compressor shell with the rotating axis of the rotating shaft as center, and is used for compressing gas flowing in from the intake port; a guide cone isarranged on the side, near the intake port, of the compressor impeller; a desuperheater nozzle is arranged in the intake channel from the guide cone to the intake port, and is used for spraying cooling liquid to the guide cone; and through setting of the angle of spraying liquid by the desuperheater nozzle, the liquid sprayed by the desuperheater nozzle is sucked into the channel of the compressorimpeller through the guide cone to mix with main gas of the compressor, so that the desuperheater effect is improved, the compression power is reduced, and the compressor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gas compressors, in particular to a centrifugal gas compressor desuperheater with a central nozzle structure. Background technique [0002] Gas compression technology such as air and water vapor has broad application prospects and great development potential in chemical industry, refrigeration industry, wastewater treatment and other fields. Mechanical steam distillation technology, superheated steam drying technology, and steam fans used in industrial engineering all involve or rely on water vapor compression technology. Studying and mastering gas compression technology can improve compression efficiency, improve system reliability and life, and bring about revolutionary changes in related fields. [0003] Under normal circumstances, the compressor only inhales gas. However, when the system is actually running, it is often due to the unstable operation of the gas-liquid separator, the liquid level of th...
