[0002] At present, the main methods of kitchen fume purification are electrostatic purification, liquid washing purification and mechanical purification. When electrostatic purification is used, there is oil in the flue, which poses a great fire hazard, and the cost of later cleaning is high. Cleaning will cause water pollution and high energy efficiency; when liquid washing purification is used, water is often used as an adsorption medium, and long-term operation also has water pollution problems. At the same time, there is a big odor problem; when traditional mechanical purification is used, the filter components such as the screen in the filter device have limited adsorption capacity for fume droplets or other particles in the fume airflow, which results in the inability to fully filter the fume liquid or other particles in the airflow, which in turn leads to low purification efficiency of the mechanical purification method.
