| titleOfInvention | Pyromellitic acid anhydride oxidized waste water Resource comprehensive utilization device |
| abstract | The invention discloses a kind of pyromellitic acid anhydride oxidized waste water Resource comprehensive utilization devices, waste water storage pond including storing oxidized waste water, several the first distillation stills in parallel are connected with behind waste water storage pond, the sour water storage tank that sour water is distillated in the first distillation still of storage is connected on the autoclave body of first distillation still, the bottom of the first distillation still is connected with crude product cis-butenedioic anhydride storagetank；Crude product cis-butenedioic anhydride storagetank is connected by pipeline with dissolution kettle, filter, centrifugal device, drying machine and packing machine are followed successively by after dissolution kettle, centrifugal device is also connected with after-fractionating kettle, and the top of the autoclave body of after-fractionating kettle is connected with heat exchanger, and acetic anhydride storage tank is led to after heat exchanger.The present invention can realize the zero-emission of water resource recycled with waste water, comply with environmentally protective sustainable development, and the present apparatus can turn waste into wealth, and by the high added value production cis-butenedioic anhydride purification production in oxidized waste water, improve the economic benefit of company. |
