Description

Technical Field

[0001] The utility model relates to the technical field of compression devices, in particular to a compression device for a brine concentration and evaporation system. Background Art

[0002] At present, centrifugal compressors are often used as secondary steam compression devices in the evaporation systems used for brine concentration in the salt making industry and the salt chemical industry. However, since there are no airflow regulating devices at the inlet and outlet of the compression device, it is easy for the compression device to be impacted by excessive airflow fluctuations, which is not conducive to the protection of the compressor. At the same time, since the effective operation of the compression device is within a certain range of working conditions, the current compression device is difficult to meet actual production needs and is not conducive to energy saving.

[0003] A Chinese patent with authorization announcement number CN201982325U discloses a compression device for a brine concentration and evaporation system, which includes an impeller, an air inlet, and an air outlet, wherein the air inlet is connected to a steam scrubber via a pipeline, and the air outlet is connected to a supersaturation elimination device via a pipeline, and the air inlet is provided with a blade-type airflow adjustment device. The utility model discloses a compression device for a brine concentration and evaporation system. After the blade-type airflow adjustment device is provided at the air inlet, the air intake of the compression device can be adjusted minutely or significantly by rotating the blades of the airflow adjustment device quickly and accurately, so that the airflow entering the compression device does not fluctuate significantly, reducing the impact of the airflow, thereby increasing the service life of the compressor, and at the same time, realizing stepless and variable operating conditions of the compressor to meet production needs.

[0004] However, the above technical solution has the following defects: the compression device of the brine concentration and evaporation system drives the multiple blades on the central axis to rotate synchronously through the connecting rod mechanism during adjustment. The blades can rotate on the central axis, and the gas will blow the blades when passing through the blades, causing the blade angle to change. Utility Model Content
