| titleOfInvention | Active adjustment type acetaldehyde separation system for aldehyde removal tower |
| abstract | The utility model belongs to the technical field of the acetaldehyde separation, concretely relates to an active adjustment formula acetaldehyde piece-rate system for aldehyde removal tower. The device comprises an aldehyde removing tower, wherein the aldehyde removing tower is connected with a distributor through a distillation pipe, the distributor is divided into two pipes, namely a distribution return pipe and an extraction pipe, the distribution return pipe is communicated with the aldehyde removing tower, the extraction pipe is communicated with a distillation tank, the distillation tank is provided with a distillation pump, the distillation pump is divided into two pipes, namely a forced return pipe and a delivery pipe, the forced return pipe is communicated with the aldehyde removing tower, and the delivery pipe is communicated with a rectification section; the forced reflux pipe, the delivery pipe, the distribution reflux pipe and the extraction pipe are all provided with pipeline valves, and the forced reflux pipe is also provided with an adjusting valve. The setting of the forced reflux pipe and the secondary reflux are realized, and the reflux quantity is adjusted by the adjusting valve on the forced reflux pipe, so that the top temperature is further controlled, the operation of the aldehyde removing tower is obviously stable, and the quality of the acetaldehyde on the top of the tower can meet the requirement. |
