Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separators, in particular to a liquid recovery device for an oil mist separator. Background Art

[0002] Oil mist separator is a device used to separate oil mist particles in the air. Oil mist is a pollutant often produced in compressed air systems. It can be caused by the lubricating oil of mechanical equipment or the oil seal leakage of the compressor. The working principle of oil mist separator is usually to use multi-stage filtration and centrifugal separation methods. First, the larger oil mist particles are filtered out through the coarse filter; then, the air is passed through the fine filter to further remove the smaller oil mist particles; finally, the remaining tiny oil mist particles are separated from the air through the centrifugal separator. The main advantages of oil mist separator include: effective removal of oil mist particles and improved air quality; reducing pollution to the environment and protecting the normal operation of equipment; extending the service life of equipment and reducing maintenance and replacement costs; improving the efficiency of compressed air systems and saving energy. Oil mist separators are widely used in various industrial fields, especially in equipment such as turbines, compressors, gas engines and lubrication systems. According to the specific application requirements and air quality requirements, different types and specifications of oil mist separators can be selected. The liquid separated and generated in the oil mist separator needs to be recovered, which requires the use of a recovery device.
