| titleOfInvention | System for recycling caprolactam from extraction water for producing polyamide-6 chips |
| abstract | The utility model discloses a system for recycling caprolactam from extraction water for producing polyamide chips. The system comprises a triple-effect evaporator, a concentrate tank and a cracker, wherein the triple-effect evaporator is used for concentrating extraction water; the concentrate tank and the cracker are connected with the outlet of the triple-effect evaporator; a heating sleeve and a self-circulation pipeline are arranged outside the concentrate tank; the outlet of the concentrate tank is connected to two filters through a switch valve; the filters are connected to the inlet of the cracker through a conveying pipeline; a conveying pump and a flowmeter are arranged on the conveying pipeline. The system for recycling caprolactam from extraction water for producing polyamide-6 chips disclosed by the utility model is characterized by further comprising a caprolactam storage tank, wherein the caprolactam storage tank is also connected to the inlet of the cracker through a liquid supply pipe; a liquid supply valve is arranged on the liquid supply pipe. According to the utility model, when the filters get out of order and flow on the conveying pipeline is fluctuated or cut off, the liquid supply valve can be opened artificially or automatically; caprolactam solution stored in the caprolactam storage tank can be supplied into the cracker, therefore, the liquid level in the cracker is steady; the quality of products is ensured. |
