[0002] Eugenol is one of the main ingredients extracted from the buds, leaves and stems of the clove tree. Eugenol has a unique aromatic taste and is therefore widely used in food, spices, medicine and other fields. In the preparation process of eugenol, the tail gas absorption tower is used to collect and treat the waste gas generated. These waste gases contain droplets and foam. If they are not treated, they will cause blockage and reduce the absorption rate. Therefore, it is necessary to add an anti-blocking and defoaming device.
