| titleOfInvention | A kind of DMF or DMAC waste gas waste water series treatment system and method |
| abstract | The invention is applicable to the technical field of DMF/DMAC waste treatment, and provides a DMF or DMAC waste gas and waste water series treatment system, comprising: a waste liquid concentration component, which is used for forcibly circulating heating and flashing the waste liquid, so as to The gas phase obtained by flashing is concentrated; the waste gas treatment component is used for collecting and treating the waste gas to make it into waste liquid; and the rectification and deacidification component is used for rectifying and deacidifying the waste liquid. The beneficial effects of the present invention are: : First of all, in the concentration process, the temperature of the steam compressor, thin film evaporator and forced circulation heater is controlled to prevent the decomposition of dimethylamine, so that the content of dimethylamine in the water discharged after concentration is extremely low, so that the water can It can be recycled back to the production line, which solves the problem that the existing multi-effect evaporation and concentration consumes a large amount of steam and the cost is high. |
