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
The present invention relates to water pretreatment system at the bottom of a kind of watercraft engine room, belong to water-treatment technology field at the bottom of watercraft engine room.
Background technology
The water of releasing of some equipment generally can be there is in watercraft engine room, be collected in bilge well after this part water of releasing generally discharges, daily bilge pump is adopted to be extracted out by sewage, deliver to bilge water and deposit cabin, it is the cabin of depositing sewage that the bilge deposits cabin, generally there are two kinds of modes to the process of wherein sewage: one is when beaching, sewage is transported to and processes on the bank, another kind is that cabin bottom position arranges oil water separator, adopt oil water separator by greasy dirt filtering, the sewage after greasy dirt filtering is directly discharged and enters sea.
These two kinds of modes of the prior art all can cause bilge water to deposit the dirt long term accumulation such as dirt, foreign material in cabin, cannot discharge, need crewman regularly to enter to clear up, and bilge water deposits cabin often fitfull shape, be furnished with again the obstacle such as pipeline, casing simultaneously, personnel's turnover is very inconvenient, and the manpower of at substantial during cleaning is very inconvenient.
To sum up, the shortcoming of prior art:
1) bilge water deposits reality in cabin at bilge water is also that natural sedimentation occurs, and can become silted up, need crewman's periodic cleaning, otherwise bilge water deposits the moisture storage capacity in cabin by influenced at bilge portion fouling knot.And the bilge water generally designed deposits freight space bottom cabin, personnel enter very inconvenient, and in cabin, ventilation condition is poor, and desilting process labour intensity is very large, is unfavorable for the safety and health of crewman.
2) bilge water, all will enter bilge oily water separator and be separated, until outboard is discharged in rear permissions up to standard, now bilge water oil content content is still higher, needs disconnector to work for a long time, neither energy-conservation also not environmentally, work efficiency is also very low.
Summary of the invention
For above-mentioned shortcoming, object of the present invention is exactly by increasing cabin bilge water pretreatment unit, improving and eliminate above-mentioned situation, makes bilge water treatment scheme more efficient, meets the requirement of boats and ships energy-saving and environment friendly of new generation.
The present invention takes following technical scheme:
Water pretreatment system at the bottom of a kind of watercraft engine room, comprises the bilge well connected successively, daily bilge pump, renovating tank for limber water, bilge water deposits cabin; The height of described renovating tank for limber water deposits cabin higher than bilge water; Sewage in bilge well is evacuated in renovating tank for limber water by described daily bilge pump, carry out sedimentation and filtration, sewage in renovating tank for limber water gravitate after sedimentation and filtration deposits cabin to downstream to bilge water, and the bilge water sewage deposited in cabin is transported to bilge oily water separator and carries out oil separation under the effect of oil separation pump.
Further, described bilge oily water separator carries oil separation pump.
Further, water at the bottom of described watercraft engine room refers to drainage water, daily water, operating water that the equipment in watercraft engine room produces in work operational process, and the equipment in described watercraft engine room comprises main promotion diesel engine, diesel-engine generator, boiler, centrifugal oil separator, oil supply unit.
Further, described renovating tank for limber water is also connected with dregs of fat cabin, is filtered in dregs of fat cabin by greasy dirt thing.
Further, there is in the bilge renovating tank twice vertical clapboard, cabinet is divided into region, three, left, center, right, left side is communicated with at the bottom of cabinet with middle part, middle part is communicated with on cabinet top with right side, and arrange profit relief outlet near left side, right side partition, profit relief outlet position is a little less than right side partition overhead height; Bilge renovating tank is provided with liquidometer, full level alarm liquid level switch, man-hand hole, ventilation mouth; Bilge water is natural sedimentation layering in bilge renovating tank, and sludgd deposition is at the bottom of the cabinet of left side, and greasy dirt floats on liquid level upper strata, left side, and comparatively clean water is gathered between twice dividing plate; The greasy dirt floating on upper strata regularly manually to be released to dregs of fat cabin on ship by crewman by self-closing escape cock; Comparatively clean water gathers precipitation until overflow enters on the right side of cabinet in the middle part of cabinet again in lattice shelves; Be positioned at the bilge water on the right side of cabinet, again natural layering, the sewage that oil-containing is lighter is collected into dregs of fat cabin by self-closing escape cock again; Bilge water after clarification manually valve drainage deposits cabin to bilge water; The mud deposited on the left of cabinet, carries out desilting when boats and ships periodic maintenance by man-hand hole.
Beneficial effect of the present invention is:
1) by arranging renovating tank for limber water, by leading filterings of impurity such as mud foreign material, substantially increasing and entering the clean-up performance that bilge water deposits the sewage in cabin.
2) regularly enter bilge water without the need to crewman to deposit cabin and clear up, because bilge water deposits cabin often fitfull shape, be furnished with again the obstacle such as pipeline, casing, personnel's turnover is very inconvenient simultaneously, greatly reduce the labour intensity of crewman, improve safety.
3) due to bilge water, to deposit cabin ventilation condition very poor, present invention, avoiding the impact of harsh environment on crewman's health.
4) by renovating tank for limber water, tentatively can reduce bilge water and deposit greasy dirt concentration in cabin, the separation of oil content makes the workload of oil water separator alleviate the work-hours that can reduce oil water separator, improves the work efficiency of oil separation, energy-conserving and environment-protective.
5) renovating tank for limber water and bilge water deposit the structure that cabin is designed to difference of height, utilize gravity directly to pour the water of bilge renovating tank into the bilge and deposit cabin, renovating tank manufacture simplification, good energy-conserving effect.
6) design of bilge water pretreatment cabinet is ingenious, adopts gravitational settling+isolation overflow+reppd mode, makes the greasy dirt in bilge water and solid impurities in pretreatment cabinet, obtain abundant actv. and is separated, do not affect by extraneous vibration, pump suction etc.
