This utility model relates to the field of pulping machine technology and discloses an environmentally friendly grinding and pulping machine, including a frame. A pulping chamber is fixedly installed in the inner cavity of the frame, and a grinding chamber is fixedly installed on the top. A feeding chamber is fixedly installed on the top of the grinding chamber. Two grinding rollers are symmetrically and rotatably installed on the inner wall of the feeding chamber. Gears are fixedly connected to the outer sides of the two grinding rollers, and the power output shaft of a servo motor is fixedly connected to the outer side of one of the gears. A rotating pipe is rotatably installed on the inner wall of the pulping chamber. By connecting the end of the connecting pipe away from the rotating pipe to a water supply pipe, a water pump can be driven to discharge water through the connecting pipe to the inner wall of the rotating pipe and the outlet pipe. The inner wall of the pulping chamber is rinsed by a nozzle, and the rotating pipe can rotate to rinse, ensuring automated and comprehensive cleaning. A screening screen is used to separate large volumes of material, reducing the solids in the pulp.

The application provides a cyclododecatriene preparation reaction post-processing process and system, which comprises the following steps: a termination process, in which a termination agent is mixed with a CDT reaction solution to perform catalyst quenching, so as to obtain a first mixture; wherein the termination agent comprises an alcohol, a phenol or a mixed solution of the alcohol and the phenol; a first extraction process, in which lye is used to extract the first mixture after cooling operation, so that a first oil phase is obtained and input into a second extraction process; and the second extraction process, in which pure water is used to extract the first oil phase, so that a second oil phase is obtained and input into a subsequent rectification separation process to obtain a cyclododecatriene product with high purity. The catalyst inactivation effect of the process is good, the loss rate of the CDT product obtained after the subsequent rectification separation is reduced, and the product recovery rate is high; the CDT reaction solution treated by the process avoids the equipment corrosion problem in the subsequent process, can reduce the equipment investment cost, simultaneously reduces the solid content and ensures the stable and continuous operation of the device.
