Problems solved by technology

[0005] In addition, in the prior art, due to the unreasonable structural setting of the ship bilge oily sewage separator, the oil-water separation efficiency is low, which affects the oil-water separation efficiency, and the oily sewage may need multiple cycles of treatment to treat the sewage to the discharge standard
[0006] In the prior art, due to the relatively humid environment of the ship, the PLC controller may be damaged at any time, resulting in failure to work normally and affecting the treatment and discharge of oily sewage

Abstract

The present invention provides a PLC-based ship oily sewage monitoring and discharging system, said system comprising: a host computer, a PLC controller, also known as an electric control box, and a ship bilge oily sewage separator, said host computer passing through a The PLC controller is connected, and the upper computer is used to monitor the working state of the PLC controller and issue a control program to the PLC controller; the PLC controller is connected to the ship bilge oily sewage separator, When the PLC controller monitors that the sewage separated by the ship bilge oily sewage separator meets the discharge standard, the PLC controller controls the ship bilge oily sewage separator to discharge the sewage overboard. The present invention greatly improves the separation efficiency of oil and sewage by setting the ship bilge oil and sewage separator with a specific structure, specially designs the inclined plate assembly, and uses the upper computer to monitor the working state of the PLC controller in real time, and when it is judged to be abnormal, it will emit a sound Light the alarm signal and make it stop working, ensuring the safety of the system.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to a PLC-based monitoring and discharging system for ship oily sewage. Background technique [0002] Ship sewage can be generally divided into two categories: domestic sewage and oily sewage: domestic sewage includes black water and gray water (kitchen gray water, washing gray water), and oily sewage includes bilge oily sewage, oil tank ballast water, tank washing water . As countries around the world pay more and more attention to the marine environment, the discharge of ship sewage is currently facing the following challenges: (1) more stringent regulatory requirements; (2) higher hydraulic load and more organic pollution (3) Zero discharge requirements in special sea areas. [0003] At present, the traditional relay contact oil-water separation control system used in real ships, because the motor and its control equipment have been working in a humid, salt spray and du...
