Description

Technical Field

[0001] This utility model relates to the field of DMSO waste liquid recovery technology, specifically a wastewater DMSO distillation concentration and recovery device. Background Technology

[0002] Dimethyl sulfoxide (DMSO) is a colorless, transparent liquid, miscible with water and most organic solvents. Pure DMSO has a distinctive odor. In industrial production processes, DMSO is sometimes required, generating large amounts of DMSO wastewater after various steps. This wastewater has a strong odor and high organic content; direct discharge would cause serious environmental pollution and waste resources. Therefore, subsequent treatment requires the use of DMSO distillation and concentration recovery devices to concentrate and recover the organic components from the wastewater.

[0003] However, during the actual use of the DMSO distillation concentration and recovery device, some odorous and harmful gases such as dimethylamine and carbon monoxide are generated during the heating and concentration process of DMSO wastewater. The subsequent treatment is difficult. At the same time, the device does not have the means to pre-purify the exhaust gas generated during the DMSO waste liquid recovery and treatment process.

[0004] Now, a novel wastewater DMSO distillation, concentration, and recovery device is proposed to address the aforementioned shortcomings. Summary of the Invention
