[0029] In summary:

[0030] 1. By using a first-stage distillation column 1, a second-stage distillation column 2, and a third-stage distillation column 3 in rotation, the cleaning agent can be purified through multiple distillations. This effectively removes impurities and dirt from the cleaning agent, improving the purity of the recovered cleaning agent. Compared to single-stage distillation equipment, this invention can meet higher purity requirements in various application scenarios, expanding the application range of recovered cleaning agents. Furthermore, the use of multiple distillation columns allows for repeated distillation purification of the cleaning agent. Through the sequential action of different distillation columns, impurities and dirt in the cleaning agent can be removed more thoroughly, effectively improving the purity of the recovered cleaning agent and meeting higher purity requirements. The multi-stage distillation column design enables continuous production; while one distillation column is performing distillation operations, other distillation columns can be prepared or cleaned, improving the efficiency of the entire recovery process. Compared to the intermittent operation of single-stage distillation equipment, it can complete the recovery of cleaning agents much faster.

[0031] 2. By employing a heating pipe 17 on one side of the steam boiler 7, the steam generated at the top of the previous distillation column serves as the heat source for the next distillation column during the multi-stage distillation process. This fully utilizes the waste heat of the steam, reduces energy consumption, and further reduces heat loss through the insulation layer 10 on the steam delivery pipeline. This improves energy efficiency and reduces recovery costs. By using the steam generated at the top of the previous distillation column as the heat source for the next distillation column, the waste heat of the steam is fully utilized. In this way, during the multi-stage distillation process, there is no need to provide a large heat source for each distillation column separately, greatly reducing energy consumption and improving the energy efficiency of the entire recovery equipment. The insulation layer 10 on the steam delivery pipeline further reduces heat loss. This ensures that the steam maintains a high temperature and energy level during transportation, providing a more stable heat source for the next distillation column, which helps improve the stability and reliability of the entire distillation system and guarantees the smooth operation of the multi-stage distillation process.
