| titleOfInvention | High-pressure pump sealing water system for urea production |
| abstract | The utility model discloses a high-pressure pump sealing water system for urea production, which comprises a vapor-liquid separation tank, a first heat exchanger, a second heat exchanger and a filter, wherein the vapor-liquid separation tank is connected with the first heat exchanger; the inlet of the vapor-liquid separation tank is connected with a gasification workshop process condensate system, the steam outlet of the vapor-liquid separation tank is connected with the heat source inlet of the first heat exchanger, the heat source outlet of the first heat exchanger is connected with the heat source inlet of the second heat exchanger, the heat source outlet of the second heat exchanger is connected with the inlet of the filter, the cold source inlet of the second heat exchanger is connected with the desalted water system, the cold source outlet of the second heat exchanger is connected with the cold source inlet of the first heat exchanger, and the cold source outlet of the first heat exchanger is connected with the desalted water system. The process condensate of the gasification workshop is used for replacing an original sealing water system, so that the water quantity is ensured, the water pressure is ensured to be stable, and meanwhile, the process condensate does not contain salt and salt, so that foreign matters such as rust slag and the like cannot be generated in a pipeline; and the process condensate is used for heating desalted water, so that the heat of the condensate is recycled, and the energy waste is avoided. |
