| titleOfInvention | A kind of recyclable device for paint stripper waste liquid |
| abstract | The utility model relates to a kind of recyclable devices for paint stripper waste liquid.The utility model is using N-METHYLFORMAMIDE and diethylene glycol monomethyl ether in extraction next door rectificating method recycling paint stripper waste liquid, king-tower and secondary tower rectifying separation by paint stripper waste liquid by extraction next door rectifying column, respectively obtain N-METHYLFORMAMIDE crude product and diethylene glycol monomethyl ether crude product, N-METHYLFORMAMIDE crude product passes through N-METHYLFORMAMIDE treating column and demetalization tower, obtain N-METHYLFORMAMIDE, diethylene glycol monomethyl ether crude product passes through diethylene glycol monomethyl ether treating column and demetalization tower, obtains diethylene glycol monomethyl ether.Using this device can continuous production, realize the separation of N-METHYLFORMAMIDE and diethylene glycol monomethyl ether, have that separation product purity is high, process flow is simple, simultaneously effective reduce the investment of the energy consumption and equipment of separation process. |
