Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a diluent distillation device. Background Technology

[0002] The diluent also functions as a cleaning agent, effectively removing esters adhering to the panel surface. However, as the cleaning process continues, the diluent gradually becomes saturated. At this point, the saturated diluent not only contains dissolved target contaminants such as esters but also contains light impurities, resulting in a significant decrease in its cleaning performance. Therefore, it must be recycled. This recycling process mainly consists of two core steps: distillation and purification. The former mainly separates and removes solid residues and some high-boiling-point impurities from the system, laying the foundation for subsequent purification. The latter, through precise control of temperature and pressure, utilizes the differences in boiling points of the components to achieve efficient separation of esters from the diluent, ultimately obtaining a diluent with a purity that meets the requirements for reuse.

[0003] However, existing diluent distillation equipment generally lacks necessary filtration components before the raw material enters the distillation equipment. This results in impurities such as solid particles and flocculents mixed in the saturated diluent directly entering the distillation and rectification system. These impurities will deposit and form scale in the distillation vessel, weakening the heat transfer efficiency of the equipment and forcing the system to consume more energy to maintain operation. Subsequently, impurities that are not intercepted may also adhere to the surface of the trays or packing of the distillation column, blocking key gas-liquid contact channels and directly disrupting the distillation equilibrium state in the column. Ultimately, this will cause a sharp drop in separation efficiency, resulting in the purified diluent failing to meet the standard requirements. Utility Model Content
