Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, specifically a recycling and treatment device for low-temperature distillation wastewater. Background Technology

[0002] Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a liquid mixture or liquid-solid system. It involves evaporating the lower-boiling-point component and then condensing it to separate the entire component. It is a unit operation combining evaporation and condensation. Compared to other separation methods such as extraction, filtration, and crystallization, its advantage lies in the fact that it does not require the use of solvents other than those used in the system, thus ensuring that no new impurities are introduced.

[0003] Patent application CN215559110U discloses a device for recycling and reusing alcohol distillation wastewater. The device includes a distillation tower with multiple sets of first fixed legs evenly connected to its bottom. A support frame is connected to the top of the base plate, and a control panel with a display screen is mounted on the support frame. A liquid discharge pipe is connected to the bottom of a collection cylinder, and a second switch valve is installed on the liquid discharge pipe. The wastewater containing heat generated during the distillation process is pumped into the collection cylinder by an electric water pump. After being heated by an annular electric heating plate, the wastewater generates steam suitable for alcohol distillation. The steam is then introduced into the distillation tower through a gas delivery pipe for alcohol distillation. This invention enables the full reuse of the wastewater containing heat generated during alcohol distillation, avoiding energy waste and promoting energy conservation, emission reduction, and lower production costs for enterprises.

[0004] However, the production efficiency of the distillation wastewater recovery devices disclosed above is generally low. During use, some distillation waste residue will adhere to the inner wall of the distillation equipment, and there is a lack of an efficient scraping and feeding structure. Utility Model Content
