Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The invention is produced in combination with the design of the engine room bilge water system of the bulk carrier. Ship engine room bilge water refers to the equipment in the ship engine room, such as main propulsion diesel engine, diesel generator, boiler, oil purifier, oil supply unit, etc. water etc.

[0027] Such as figure 1 As shown in , there are sewage wells for collecting bilge water in the engine room, two at the head of the engine room and one at the rear;

[0028] Use the daily bilge pump to pump the bilge water in the engine room to the bilge water clarification tank;

[0029] Two partitions are designed inside the clarification cabinet to divide the cabinet into three areas: left, middle and right. The left side and the middle part are connected at the bottom of the cabinet, and the middle part and the right side are con...

Abstract

The invention relates to a cabin bilge water preprocess system for a ship. The cabin bilge water preprocess system is characterized by comprising sewage wells, a daily service cabin bilge pump, a bilge water clarifying tank and a bilge water storage cabin which are sequentially connected, wherein the height of the bilge water clarifying tank is higher than that of the bilge water storage cabin; sewage in the sewage wells is pumped to the bilge water clarifying tank through the daily service cabin bilge pump, and is precipitated and filtrated; after the sewage in the bilge water clarifying tank is precipitated and filtrated, the sewage flows downwards to the bilge water storage cabin under the action of gravity; the sewage in the bilge water storage cabin is transported to a bilge water oil-water separator under the action of an oil-water separation pump, so that oil-water separation is performed. According to the cabin bilge water preprocess system disclosed by the invention, the oil content of the bilge water actually drained into the bilge water storage cabin is substantially decreased, the work load of the bilge water oil-water separator can be effectively reduced, and the cabin bilge water preprocess system is environment-friendly and energy-saving; the dreg content of the bilge water actually drained to the bilge water storage cabin is substantially decreased, so that the work difficulty and the work intensity of seamen for desilting can be effectively reduced.

Description

technical field [0001] The invention relates to a ship engine room bilge water pretreatment system, which belongs to the technical field of ship engine room bilge water treatment. Background technique [0002] There is generally some equipment discharge water in the engine room of the ship. This part of the discharge water is generally discharged and collected into the sewage well. The sewage is pumped out by the daily bilge pump and sent to the bilge water storage tank. The bilge storage tank is used for storing sewage. There are generally two ways to treat the sewage in the cabin: one is to transport the sewage to the shore for treatment when the ship is docked, and the other is to install an oil-water separator at the bottom of the cabin, and use the oil-water separator to filter out the oil. , The sewage after the oil pollution is filtered is directly discharged into the sea. [0003] These two methods in the prior art will cause long-term accumulation of dirt, sundries...
