This application discloses a multi-boiler intermodal system, relating to the field of generator set technology. It includes multiple boilers and multiple steam turbines. Each boiler's main steam pipe is connected to a common main steam header. Each steam turbine corresponds one-to-one with one of the boilers. The main steam header distributes main steam to the high-pressure cylinders of each turbine as needed. Each turbine's high-pressure cylinder sends exhaust steam to the boiler reheater via a reheat cold section pipe and a reheater inlet pipe. Each reheat cold section pipe is equipped with a make-up steam pipe. Each boiler reheater sends steam to the intermediate-pressure cylinder of the turbine via a reheat hot section pipe. Each reheat hot section pipe is equipped with an extraction steam pipe. This application can ensure that the main steam, cold reheat, and hot reheat parameters are consistent with the operating requirements of each system device, and can achieve decoupling of the boiler and turbine units, promoting flexible unit operation.

The present application relates to a long-acting antibacterial polyamide fiber and a preparation method thereof. The long-acting antibacterial polyamide fiber is composed of 4wt%-20wt% nylon-guanidine salt copolymer master batch and 80wt%-96wt% nylon, and the preparation method comprises the following steps: melt blending and reacting polystyrene-guanidine salt copolymer functional material obtained by melt blending and reacting polycyclic epoxy polystyrene synthesized by solution polymerization, suspension polymerization or bulk polymerization and guanidine salt polymer antibacterial agent; then melt blending with nylon to obtain nylon-guanidine salt copolymer master batch; and finally melt blending and spinning with nylon to obtain long-acting antibacterial polyamide fiber. By using the nylon-guanidine salt copolymer master batch of the present application, on the one hand, the antibacterial agent is chemically bonded to the polyamide matrix, ensuring the long-acting antibacterial property of the fiber; on the other hand, the antibacterial agent is enriched on the surface of the antibacterial polyamide fiber. The long-acting antibacterial polyamide fiber exhibits excellent antibacterial performance at a lower antibacterial agent dosage, thereby simultaneously maintaining good mechanical properties.
