Ship deck blowdown system

Abstract

The invention relates to the technical field of ships, and discloses a ship deck blowdown system. The deck is a horizontal deck, a plurality of mounting grooves are formed in the deck; a floor drain group is arranged in each mounting groove; the floor drain set comprises a plurality of floor drains arranged in a line and a water collecting pipe communicated with each floor drain. The two groups ofpollution discharge mechanisms are respectively arranged on the larboard and the starboard; each group of sewage discharging mechanism comprises a sewage well, a water-oil separator, an oil stain detector, a water discharging pipe, an oil discharging pipe and a liquid discharging pipe; two ends of the water collecting pipe are respectively connected with the two sewage wells; the sewage well is connected with the water-oil separator, a first control valve is arranged at the liquid outlet end of the sewage well, the water outlet end of the water-oil separator is connected with a drain pipe provided with a second control valve, the oil outlet end of the water-oil separator is connected with an oil drain pipe, the oil stain detector is arranged on the drain pipe, and the drain pipe is connected with the oil drain pipe through a liquid drain pipe provided with a third control valve. By the adoption of the device, sewage on a deck can be efficiently discharged, and pipeline installation isfacilitated; and the discharged sewage is ensured to meet the standard.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship deck sewage discharge system. Background technique [0002] With the rapid development of shipping and the diversification of ship types, the demand for ro-ro ships is increasing. The cargo deck surface of this type of ship requires continuous flatness to meet the requirements for carrying cargo or fixing large-scale operating tools, so as to prevent the deck from tilting and causing cargo damage. Safety accidents such as rollovers and slippages cause property damage and endanger personal safety. Therefore, the occurrence frequency of horizontal decks is getting higher and higher, and the requirements for ship construction precision and deck drainage system are becoming more and more strict. However, the distribution of leaks is scattered, the pipeline layout is intricate, and it is difficult to repair leaks and pipelines. Or, the hull structure has a beam arch when buildin...

AI Technical Summary

Problems solved by technology

The water leaks are arranged on both sides of the ship's side, and the accumulated water flows along the deck slope to the side, and is discharged outboard through the water leakage again. However, the ship's deck must adopt a beam-arch deck, which makes the hull structure complex and consumes more steel.
