This application belongs to the field of battery production line technology and discloses a steam condensate recovery and utilization system and a battery production line. The steam condensate recovery and utilization system includes a first water tank, a second water tank, and a hot water supply device. The first water tank forms a first receiving cavity and has a first inlet, a second inlet, and an outlet, all connected to the first receiving cavity. The first inlet is used to connect to the steam condensate supply device in the battery production line. The second water tank forms a second receiving cavity and has a third inlet connected to the second receiving cavity. The water inlet of the hot water supply device is connected to the outlet via a circulation pump, and its water outlet is connected to both the first and third inlets. During the process of the circulation pump pumping the steam condensate from the first water tank into the hot water supply device for recycling, some of the water returning from the water outlet will enter the second water tank through the third inlet, effectively preventing the first water tank from overflowing and improving energy utilization.

The application discloses an online agent replacement unit and a reaction rectifying tower, and relates to the field of reaction rectifying tower, and aims at collecting invalid solid catalyst and / or filler particles suspended in liquid phase in the reaction rectifying tower. The online agent replacement unit comprises a receiving tray which is arranged on the inner wall of the reaction rectifying tower and is located above the liquid surface; a rotating mechanism which is arranged on one side of the inner wall of the tower and corresponds to the position of the receiving tray; the rotating mechanism is controlled to rotate by a driving unit outside the tower; a plurality of fixed pin shafts are uniformly and spacedly arranged at the outer periphery of the rotating mechanism; the highest point of the rotating mechanism is higher than the arranged position of the receiving tray, and the lowest point is located below the liquid surface and close to the tray plate; the number of collecting baskets is equal to that of the pin shafts, and the collecting baskets are hung on the pin shafts; the collecting baskets collect the solid particles suspended in the liquid phase when the rotating mechanism rotates to below the liquid surface, and dump the solid particles to the receiving tray at the highest point. The application is suitable for gas-liquid-solid reaction, and can recycle the invalid catalyst and / or filler particles on line.
