Description

Onboard bilge water treatment unit {APPARATUS FOR DISPOSITION OF BILGE WATER IN A SHIP}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating bilge water occurring on board, and more particularly, to an apparatus for concentrating bilge water.

Conventionally, when water leaked from a shell or pipe, water from a cargo, or water falling from a deck sends sewage (hereinafter referred to as bilge water) to the bottom of a ship to an onshore recovery facility, Until now, various bilge water treatment apparatuses for concentrating on board have been proposed.

As such a conventional inboard bilge water treatment apparatus, there exist some as shown to FIG. 4 and FIG. 5, respectively.

In the conventional apparatus shown in FIG. 4, the bilge water concentration tank 1 and the concentrated bilge water storage tank 2 are provided separately, and these tanks 1 and 2 are connected to the concentrated bilge water discharge pipe 3 through the tank. have.

And the bilge water is sent to the tank 1 through the piping 4. The bilge water in the tank 1 is circulated through the bilge water circulation pipe 6 by the pump 5, and at this time, the bilge water is sprayed into the tank 1 by the bilge water spray pipe 7. Lose.

In addition, a heat exchanger 8 is provided below the bilge water spreading pipe 7. The sprinkled bilge water is heated by heat exchange with the hot fluid flowing through the pipes 9 and 10 into the heat exchanger 8 to promote vaporization of the contained moisture. In this way, the concentrated bilge water is led from the lower part of the tank 1 to the concentrated bilge water storage tank 2 through the concentrated bilge water discharge pipe 3.

Moreover, the blower pipe 11, the discharge part 12, and the blower 13 are arrange | positioned in order to accelerate the water vaporization of the bilge water in the tank 1, and to discharge | evaporate water vapor. The blower 13 sends air through the blower pipe 11 provided below the heat exchanger 8 above the liquid level in the lower part of the tank 1. Thereby, the water vapor of the bilge water in the tank 1 is discharged out of the tank through the discharge part 12 while the droplet is removed by the demister 14.

In addition, the concentrated bilge water in the concentrated bilge water storage tank 2 is discharged from the port through the discharge pipe 15 in the lower part of the tank 2 and is returned to the land treatment facility.

In addition, the conventional apparatus shown in FIG. 5 is provided with the bilge water concentration tank 1 and the concentrated bilge water storage tank 2 separately, similarly to the conventional apparatus of FIG. 4, and is comprised with the same idea as a whole. . In addition, in FIG. 5, the same code | symbol as FIG. 4 has shown the member of the same shape. In the apparatus of FIG. 5, a recycle tube 16 is also provided for the concentrated bilge water storage tank 2, and a mixer 17 is inserted into the recycle tube 16.

However, in the conventional inboard bilge water treatment apparatus as described above, since the bilge water concentration tank 1 and the concentrated bilge water storage tank 2 are separately provided, the lower portion of the bilge water concentration tank 1 The volume of the reservoir was limited. For this reason, in the apparatus of FIG. 4, sludge and salts accumulated in the lower part of the tank 1, and there existed a possibility that a piping might be clogged. For this reason, in the conventional apparatus, the transfer of the bilge water from the bilge water concentration tank 1 to the concentrated bilge water storage tank 2 had to be performed at an early stage. As a result, as shown in FIG. In addition, piping for circulating the bilge water through the bilge water concentration tank 1 from the concentrated bilge water storage tank 2 has also become necessary. Therefore, in the above conventional apparatus, the effect of separating into the two tanks 1 and 2 is lost in the end, rather it causes the enlargement and complexity of the apparatus, and it is difficult to equip the small vessel.

SUMMARY OF THE INVENTION The present invention is intended to solve the problems as described above in a conventional apparatus. The bilge water condensation unit and the concentrated bilge water storage unit are provided in a tank to reduce the size of the apparatus, while efficiently concentrating the bilge water. It is an object of the present invention to provide an inboard bilge water treatment apparatus capable of efficiently discharging water vapor evaporated from bilge water from a discharge portion of a tank top.
