Ship deck oily water treatment system

Abstract

The invention discloses a ship deck oily water treatment system which comprises a deck drainage system, an oil content concentration analyzer and an oily water treatment device. The deck drainage system comprises multiple floor drains arranged on a ship deck; the multiple floor drains are connected to an inlet of a main drainage pipe through various branch drainage pipes; the oily water treatmentdevice comprises a sewage collecting tank, an oil-water separator and a dirty oil collecting tank; an outlet of the main drainage pipe is connected to the outboard or the dirty oil collecting tank through the branch pipes; the oil content concentration analyzer is arranged on the main drainage pipe, so that deck oily water is directly discharged to the outboard or the sewage collecting tank; an alarm device and a liquid level float switch are arranged in the sewage collecting tank, so that the oily water is discharged into the oil-water separator so as to be collected; and an outlet of the oil-water separator is connected to the outboard, the sewage collecting tank and the dirty oil collecting tank through the pipelines. According to the ship deck oily water treatment system provided by the invention, the possibility of ocean pollution can be effectively reduced, and the purchase cost and the labor load are reduced.

Description

technical field [0001] The invention relates to the field of ship drainage system design, in particular to a ship deck oily sewage treatment system. Background technique [0002] With the rapid development of industrialization, human beings exploit more and more marine resources, and the problem of marine pollution has become increasingly prominent. For example, the hydraulic oil leakage of hydraulic equipment on the open deck of ships and offshore platforms, the lubricating grease in the open area is dissolved in the rain, the more serious hydraulic system, the interface of the oil delivery system is broken, and improper maintenance leads to a large amount of oil leakage. When the above situation occurs, the oil stains will remain on the deck surface. Under the washing of rainwater, the oil stains will dissolve into the water and be discharged into the sea with the deck drainage system; even the oil stains will be directly discharged into the sea through the deck drainage s...

AI Technical Summary

Problems solved by technology

For example, the hydraulic oil leakage of hydraulic equipment on the open deck of ships and offshore platforms, the lubricating grease in the open area is dissolved in the rain, and the more serious hydraulic system and oil delivery system interface rupture, improper maintenance leads to a large amount of oil leakage

When the above situation occurs, the oil stains will remain on the deck surface. Under the washing of rainwater, the oil stains will dissolve into the water and be discharged into the sea with the deck drainage system; even the oil stains will be directly discharged into the sea through the deck drainage system, causing marine environmental pollution.

[0003] In the prior art, the main way to solve the drainage problem of the open deck is: directly discharge the rainwater into the overboard through the drain pipe without any treatment; at most, an expansion plug is installed at the deck drain pipe to prevent oil pollution from being directly discharged to the ship through the drain pipe. Overboard, but the oil stains remaining on the deck surface will be dissolved into the water under the washing of rainwater, and will be discharged into the sea with the rainwater, polluting the marine environment
