condensate drainage device for a superstructure bulkhead of a large cargo ship

The invention discloses a condensate drainage device for a bulkhead of a superstructure of a large cargo ship, comprising a water trap flat iron, a drainage outlet, a floor drain and a condensate drainage pipe. The water-retaining flat iron is fixed on the floor of each floor at a certain distance from the inner surface of the outer bulkhead of each floor so as to form a water collecting channel between the water-retaining flat iron and the outer bulkhead; The drainage outlet is arranged on the floor of the floor at the corner of the floor and is located in the water collecting tank; The floordrain is installed in the drain outlet; The upper end of the condensate discharge pipe is connected with the lower end of the floor drain, and the lower end is located in the water collecting tank ofthe next floor. A support structure is provided between the condensate discharge pipe and the inner surface of the outer bulkhead of the next floor, and the support structure is a plurality of spacedflat steels, each flat ste
