The working principle of the bilge oil-water separator is that in the working process, a plunger pump 7 is started to work, negative pressure is generated in a coalescing unit 2, oil dirt in an oil-water cabin 263 enters the coalescing unit 2 after being pretreated by a prefilter 261, namely a Y-shaped filter, on an oil-water inlet pipe 26, the oil dirt in the coalescing unit 2 utilizes the gravity effect generated by oil-water density difference to enable oil drops to gather on the upper portion of the coalescing unit 2, the oil drops float to a gravity separation chamber at the top of the coalescing unit 2, a space above a porous medium coalescing layer (81) in the coalescing unit 2 is a gravity separation chamber, when an oil dirt layer at the upper end of the gravity separation chamber in the coalescing unit 2 reaches a certain thickness, a probe of an oil-water interface instrument 23 detects oil, the oil-water interface instrument 23 sends a signal to an electric cabinet 5, the electric cabinet 5 controls the plunger pump 7 to stop running, a water draining electromagnetic valve 331 and a water return electromagnetic valve 321 are closed, and a water supplementing electromagnetic valve 252 and an oil discharging electromagnetic valve 211 are opened simultaneously, and oil discharging is carried out. As the thickness of the oil layer gradually decreases after the oil drainage time, when the water level exceeds the probe position of the oil-water interface meter 23, the probe of the oil-water interface meter 23 detects water and sends a signal for stopping oil drainage, the electric cabinet 5 can perform a time-delay oil drainage action, after the time-delay oil drainage is completed, the water supplementing valve 252 and the oil drainage electromagnetic valve 331 are closed, the oil drainage is stopped, and the plunger pump 7 continues to operate. When the oil-water interface meter 23 detects the oil again, the above-described operation is repeated.
The lower layer of the coalescing unit 2 enters the emulsifying unit 3, and finally, under the adsorption action of a separator of the emulsifying unit 3, all extremely tiny emulsified oil particles are adsorbed and separated, so that the oil content of bilge oil sewage is less than 15ppm. When water is discharged through the water discharging main pipe 31, the water is detected through the 15ppm bilge water alarming device 6, after qualified water is detected, the electric cabinet 5 can open the water discharging electromagnetic valve 331 to be discharged to the outside, and if unqualified water is detected, the electric cabinet 5 can open the water returning electromagnetic valve 321 to enter the water returning pipe 32, and the water enters the oil sewage cabin 263 again through the water returning pipe 32.
The principle of temperature self-control in the coalescing unit 2 allows the high viscosity oil in the coalescing unit 2 to drain smoothly and prevents dirty oil from adhering to the oil-water interface meter 23 and causing control failure. Specifically, the electric junction thermometer 24 is used for detecting the oil temperature of the coalescing unit 2, a signal is input into the electric control box 5, the electric control box 5 heats the heater 27, and the temperature is automatically controlled. The temperature of the electrical junction thermometer 24 is typically set at 40-60 ℃.
The automatic oil discharge principle of the coalescing unit 2 is that an oil-water interface meter 23 is arranged at the upper part of the coalescing unit 2, and corresponding signals are sent out by utilizing the difference of the conductivity of two mediums of oil water, so that the control function of opening and closing corresponding electromagnetic valves is realized, and the aim of automatic oil discharge is fulfilled.
The control box 5 is provided with a feedback signal contact of the medium control console, and can provide a device running state signal and a comprehensive fault alarm signal; the water level sensor in the oil-sewage cabin 263 is electrically connected with the control box 5, the control box 5 can receive signals of low water level and medium water level of bilge water, equipment operation can be started at the medium water level, the equipment operation can be automatically in a standby state at the low water level, and the equipment operation can be automatically restored to be in the medium water level state again; in addition, the control box can also monitor the signal of the 15ppm bilge water alarm device 6 in real time, and besides the alarm red light is used for displaying, the control box can also automatically control a corresponding electromagnetic valve for switching qualified water discharge or exceeding water return cabin of the bilge water separator.
Wherein, 15ppm bilge water alarm device 6 adopts GQS-206 oil content concentration meter, is according to international maritime organization IMO MEPC.107 (49) resolution requirement, adopts infrared measurement technical principle and advanced micro-processing technology to design 15ppm bilge water alarm device 6, generally uses with bilge water separator in coordination. The alarm is used for automatically detecting the quality of discharged water and controlling the corresponding electromagnetic valve to return the discharged water which does not reach the standard to the sewage cabin. The alarm is approved by the type of China class society, and the technical performance accords with the specification of IMOMEPC.107 (49) resolution (7 months and 18 days in 2003), in the revised anti-pollution equipment guide and technical condition for bilge water of a ship cabin, part 2, 15ppm bilge water alarm device type approval test and performance technical condition, and part 3, anti-pollution equipment type approval environmental test technical condition.
