Description

Technical Field

[0001] The utility model relates to the technical field of plasticizer wastewater, in particular to an oil-water separation and recovery device for plasticizer wastewater. Background Art

[0002] Plasticizers, also known as plasticizers, are polymer material additives widely used in industrial production. The use of plasticizers can improve the performance of polymer materials, reduce production costs, and improve production efficiency. By adding this substance during plastic processing, its flexibility can be enhanced and processing can be facilitated. Therefore, plasticizers are an important type of chemical product additives. In the existing production process of PVC wallpaper, plasticizers are often used, but plasticizers are easy to volatilize under high temperature conditions of printing, and reach the waste gas treatment facility through the waste gas collection pipe in the form of oil mist, and are eventually discharged into the atmosphere. If the treatment facility is a water spray, the oil mist will be enriched under the action of the water spray, forming an oil film on the top of the liquid surface of the water tank. Long-term accumulation will reduce the spraying effect of the water spray, so it is necessary to separate the oil from the circulating water of the spray tower;
