Abstract

The invention relates to the technical field of separation and purification of pollutants in air, in particular to an oil mist purification system and oil mist purification equipment. Comprising an oil mist interceptor, an electrostatic filter, a gas mixing device, a demister, a fan and a precision filter, the fan is arranged in the middle of the system, a negative pressure working area is formed at the front end of the fan, and a positive pressure working area is formed at the rear end of the fan. Oil mist waste gas from the CNC machine tool firstly passes through the oil mist interceptor to remove large-particle-size oil mist liquid drops and refine particle size distribution, and then enters the electrostatic filter to be subjected to electric field trapping; then the airflow enters a gas mixing device and is mixed with cold air to reduce the temperature, so that part of gaseous pollutants are condensed to form liquid drops, and the liquid drops are separated through a demister; and the treated airflow enters the fan to be pressurized, then enters the precision filter to further filter fine particles, and then is discharged. The purification efficiency of the oil mist waste gas is improved by reasonably configuring all the purification units and utilizing form transformation of pollutants in the treatment process.
