A marine dry bilge water collection system

Abstract

A marine dry bilge water collection system is disclosed. A marine dry bilge water collection system comprises a plurality of machinery spaces, a plurality of cargo compartments, a main engine compartment, a propulsion engine compartment and a bilge tank, wherein a plurality of sewage wells are arranged in the machine compartment and the cargo compartment, a plurality of sewage wells are communicated with each other through a connecting pipeline, a check valve is arranged at the connection of each sewage well and the connecting pipeline, and daily bilge pumps and bilge pumps of the main enginecompartment are arranged in the main engine compartment; One end of the main engine room daily bilge pump is communicated with each sewage well through a pipeline, and the other end is communicated with the bilge tank through a pipeline; One end of the main engine bilge pump is communicated with each sewage well through a pipeline, and the other end is communicated with the bilge tank through a pipeline; A daily bilge pump for that propulsion engine room and a bilge pump for the propulsion engine room are arrange in the propulsion engine room.

Description

technical field [0001] The invention relates to the field of ship bilge water treatment, in particular to a ship dry bilge water collection system. Background technique [0002] Bilge water refers to the bilge water in the engine room or cargo hold, and the piping system specially used to remove the bilge water is called the bilge water system. The bilge water system is mainly composed of bilge water pumps, bilge water pipelines, oil-water separators and related valves. The function of the bilge water system is to timely separate the water in the engine room and the cargo hold and discharge it to the overboard according to the needs of ship operation, so as to achieve the purpose of removing the sewage oil accumulated in the bilge of the ship. [0003] Generally speaking, for a ship in normal operation, the water volume in the bilge of the engine room is 1-10m 3 / d; When the ship is damaged, the bilge water system can also be used for emergency drainage of accumulated wate...

AI Technical Summary

Problems solved by technology

If the damaged place is located in the machinery space where the pump is located, the sewage pump and all mechanical equipment in the tank will stop working, which will cause the sewage in the tank to be unable to discharge

Even if the damaged position is blocked, the water outside the cabin cannot enter the cabin, but the water in the water inlet compartment cannot be discharged because the sewage pump cannot work

And the relevant valves connected in the cabin cannot be closed, which will affect the work of other pumps. In severe cases, the valves are not closed, which will lead to the communication between the pipelines and cause water to flow through, causing continuous danger on the ship.
