| titleOfInvention | Energy efficient system for caprolactam evaporation |
| abstract | The utility model provides an energy-saving system for caprolactam evaporation. The system is provided with a multi-effect evaporator, and each stage of the evaporator comprises an evaporation tower heater, an evaporation tower and an evaporation tower discharge pump which are connected in sequence, wherein the previous stage The gas phase outlet of the evaporation tower is connected to the heat exchange medium inlet of the next-stage evaporation tower heater; the last-stage evaporator is also provided with a cyclohexane heater, which is arranged in parallel with the last-stage evaporation tower heater. The front end of the last stage of the evaporation tower. The system also includes a compressor, which is located on the gas phase outlet pipe of the intermediate evaporation tower of the multi-effect evaporator, and the outlet of the compressor is connected to the heat exchange medium inlet of the heater of the first evaporation tower. By adopting the utility model, the consumption of the system steam can be reduced, the comprehensive utilization of the heat energy of the system can be improved, and the purpose of energy saving can be achieved. |
