[0002] Plasticizers are widely used as high-molecular material auxiliaries in industrial production, also known as plasticizers. At present, many large enterprises use plasticizers obtained by esterification reaction of benzoic acid and glycerol to produce new environmentally friendly plasticizers. Dioctyl phthalate is a kind of plasticizer, and the production process of dioctyl phthalate generally adopts batch method, semi-continuous method and full-continuous method. Among them, in the esterification process of batch production, a large amount of alcohol-water mixture is generated at the top of the reaction tower. Technologically, this part of the alcohol-water mixture needs to be condensed to recover the octanol therein to participate in the subsequent processes. A condensation device for a plasticizer disclosed in the prior art with publication number CN219494887U includes a cooling box and a circulating water tank. A water pump and a condenser are installed at the bottom of the inner cavity of the circulating water tank. The water outlet of the water pump is connected to a first connecting pipe, and the water inlet of the condenser is connected to a second connecting pipe. A partition is arranged in the inner cavity of the circulating water tank, and the partition is hollow. The water pump and the condenser are respectively arranged on both sides of the partition. The circulating water tank is arranged directly below the cooling box. Two groups of support rods are welded in the inner cavity of the cooling box, and a condensation coil is arranged in the inner cavity of the cooling box. The condensation coil is arranged in a spiral shape. However, affected by the air flow velocity, the landing point range of the alcohol-water mixture flowing out is relatively large, and a large-diameter collection container needs to be used for collection, resulting in more occupied space, and it is time-consuming and laborious to transfer the large-diameter collection container.
