Description

Technical Field

[0001] This utility model relates to the field of mother liquor recovery technology, and in particular to a mother liquor recovery device. Background Technology

[0002] The treatment of mother liquor is a crucial step in chemical production. Improper treatment can severely impact production safety and product quality. Incomplete recovery and treatment of mother liquor can lead to the release of hazardous substances into the environment, causing pollution and resource waste.

[0003] Currently, the recovery of mother liquor requires the use of a reaction vessel. The reaction vessel assists in mixing and reacting the mother liquor with chemical reagents, thus facilitating the recovery of the mother liquor. During the stirring process of mother liquor recovery, sampling is a crucial step in ensuring the reaction progress and quality control.

[0004] A prior art patent (CN221619454U) discloses a mother liquor recovery reactor, comprising a reactor body, a steam inlet pipe, a steam outlet pipe, and a waste heat recovery assembly. The steam inlet pipe and steam outlet pipe are fixedly installed on the side of the reactor body and connected to the jacket layer of the reactor body. While this device significantly improves heat conversion efficiency, its stirring system lacks any auxiliary sampling mechanism and still relies on traditional manual sampling. This results in frequent start-stop cycles for sample extraction, which not only prolongs the reaction time and reduces production efficiency but also significantly increases operational risks due to the high temperature and corrosive properties of the mother liquor. Therefore, an improvement is proposed. Utility Model Content
