| titleOfInvention | Circulation type caprolactam concentration system |
| abstract | The utility model discloses a circulating caprolactam concentration system, which comprises a circulating tank and a concentration assembly with a water inlet, a concentrated solution recovery port and a water production port, wherein the concentration assembly further comprises a shell and at least two concentration modules arranged in the shell, one end of the shell is provided with the water inlet, the other end of the shell is provided with the water production port and the concentrated solution recovery port, the water inlet and the concentrated solution recovery port are respectively communicated with the circulating tank through pipelines, the water production port is used for being communicated with the water production tank, the concentration modules are positioned between the water inlet and the water production port as well as between the water production port and the concentrated solution recovery port, a buffer cavity is arranged between every two adjacent concentration modules, a compensation port communicated with the circulating tank is arranged on the buffer cavity, a compensation pump is arranged between the compensation port and the circulating tank, and a pressure compensation device is arranged in the buffer cavity. The utility model greatly improves the concentration efficiency, improves the utilization rate of each concentration module and prolongs the service life of the whole system. |
