Description

Technical Field

[0001] The present application relates to the field of separation systems, and in particular to an alcohol-water separation device. Background Art

[0002] A high alcohol content in wastewater can easily lead to a higher COD value in the wastewater. Therefore, it is usually necessary to separate the alcohol in the wastewater before discharging it.

[0003] The Chinese patent with the authorization announcement number CN208809506U discloses an alcohol-water separation system, which belongs to the alcohol-water separation technology field. It is aimed at the separation system of high alcohols (such as hexadecanol with a boiling point exceeding 100°C, such as hexadecanol with a boiling point of 344°C), and aims to provide an alcohol-water separation system with high separation efficiency and fast separation speed. The key points of its technical solution are that it includes a condenser connected to the reactor, the condenser is connected to a negative pressure pipeline, the condenser is connected to an alcohol-water stratification tank, the condenser is connected to the reactor with a cooling tower, the bottom feed port in the cooling tower is connected to the reactor, the top discharge port is connected to the cooling tower, and the cooling tower is filled with stainless steel filler. The separation efficiency and separation speed of the alcohol-water mixture can be improved by setting the cooling tower and the stainless steel filler.

[0004] With respect to the above-mentioned related technologies, the grille is arranged at the bottom of the cooling tower. When cleaning the stainless steel filler, the operator needs to lift the grille with a lifting rope, move the grille from the bottom of the cooling tower to the top of the cooling tower, and take out the stainless steel filler through the discharge port to clean and replace the stainless steel filler. The operator needs to lift the grille a long distance, which is inconvenient to operate. Utility Model Content
