AI Technical Summary

Technical Problem

The traditional ship oil and water tank isolation method is prone to failure during wind and waves and collisions, resulting in oil and water mixing, causing environmental pollution and safety accidents.

Method used

An isolation control system for a ship's oil and water tank is designed, using an oil and water isolation plate and pressure sensors are set on both sides of it. The controller generates control parameters according to the pressure threshold, and dynamically adjusts the valve opening of the oil tank and water tank to achieve effective oil and water isolation.

Benefits of technology

It realizes dynamic adjustment of isolation intensity under different navigation conditions and responds to abnormal situations quickly, improves the safety and effectiveness of oil and water isolation, and reduces the impact on the marine environment.

Abstract

The invention provides an isolation control system, control method and equipment for an oil-water tank of a ship, and relates to the technical field of water-oil isolation, and the system comprises an oil-water isolation plate which is used for isolating an oil tank from a water tank; the first side of the oil-water separation plate is in contact with oil stored in an oil tank of the ship; the second side of the oil-water separation plate is in contact with water stored in a water cabin of the ship; the first side is coated with at least one layer of oil-resistant isolating membrane; the second side is coated with at least one layer of water-resistant isolating membrane; a first pressure sensor and a second pressure sensor are respectively arranged on two sides of the oil-water separation plate; the first pressure sensor is used for detecting the pressure value of the first side; the second pressure sensor is used for detecting the pressure value of the second side; and the controller is used for generating control parameters when the pressure value of the first side or the second side exceeds a configured pressure threshold value so as to control the corresponding oil tank or water tank to discharge oil or water outwards. The oil-water separation device can safely and stably realize effective oil-water separation.
