Description
Technical field
The utility model relates to a kind of retrieving arrangement, especially a kind of extraction recovery device of the intermediate to hexanolactam.
Background technology
When the hexanolactam material after evaporation concentration equipment is concentrated, contain a large amount of hexanolactam starting monomers and hexanolactam reaction intermediate in the gained concentrated solution, these concentrated solutions that include the intermediate of the monomer of hexanolactam raw material and hexanolactam generally all can extract through distillation method to be recycled, but the rate of recovery that distillation method reclaims is not high, can cause starting monomer and whole hexanolactam reaction intermediate of part hexanolactam directly to be discharged as residue, thereby so that increase the production cost of enterprise.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of extraction recovery device that polymer can be transformed into low molecule, reduce the intermediate of cost and utilization of waste material is provided.
In order to achieve the above object, the extraction recovery device of the intermediate that the utility model is designed, it comprises extraction tower, evaporation concentration equipment, cracking reactor, polymerizing pipe; Described cracking reactor is made of tank body, well heater, controller, and tank body is provided with four interfaces, is respectively opening for feed, cracking outlet, cracking import and discharge port; Opening for feed on the tank body is connected with evaporation concentration equipment by pipeline, and this pipeline is provided with control valve; Discharge port is connected with polymerizing pipe by pipeline, and also is provided with control valve on this pipeline; Cracking outlet on the tank body is connected by pipeline with the cracking import, and is provided with successively well heater and controller on this pipeline.
Described extraction tower is connected with evaporation concentration equipment by pipeline.
Open the control valve at opening for feed place, together enter into tank body in by pipeline the intermediate that includes raw material, water and the hexanolactam that produce in the evaporation concentration equipment, close the control valve at opening for feed place, carrying out cracking processes, and in the cracking treating processes, the control valve at opening for feed and discharge port place all is closing condition; Scission reaction is opened the control valve at discharge port place after finishing, and polymer is transformed into low molecule and is transported to polymerizing pipe re-use.
The extraction recovery device of the intermediate of the utility model gained will contain the intermediate of hexanolactam raw material by the cracking reactor cracking, and zero release is accomplished in all comprehensive utilizations again, and utilization ratio absolutely.Therefore, it has the characteristics such as easy to use, energy-conservation and reasonable in design.
