| titleOfInvention | Device for automatically monitoring acetic anhydride content |
| abstract | The utility model belongs to crude acetic anhydride production field, concretely relates to automatic device of control acetic anhydride content. The online refractometer is arranged on a bypass branched by a mixture circulating pipeline, the controller is electrically connected with the feed supplement regulating valve, the discharge valve and the online refractometer respectively, and the controller controls the feed supplement regulating valve and the discharge valve respectively according to output information of the online refractometer. Further, the controller is a PLC controller. The device has the advantages that the technical effects of immediate detection and automatic control of acetic anhydride in the production process are realized, the working efficiency of the device is high, the existing equipment can be realized without great transformation, and the economic benefit is obvious. |
