Device for monitoring and detecting water quality of ship ballast water in real time

Abstract

The invention discloses a device for monitoring and detecting the water quality of ship ballast water in real time. The device comprises a bypass pipe I, a bypass pipe II, a bypass pipe III, a bypasspipe IV and a bypass pipe V which are located on main pipelines at the inlet end and the outlet end of a ballast tank. The inlet ends of the bypass pipe I, the bypass pipe II, the bypass pipe III, thebypass pipe IV and the bypass pipe V are communicated with the outlet end of the ballast tank through a pump. The outlet ends of the bypass pipe I, the bypass pipe II, the bypass pipe III, the bypasspipe IV and the bypass pipe V are communicated with the inlet end of the ballast tank. The device is rapid in measurement speed and high in sensitivity and can display data in real time, record the treatment information of the ship ballast water and greatly shorten water quality detection time and save a large amount of time, labor, materials and financial resources, the effective control over ships and the implement of IMO ballast water convention can be easily monitored by a port state, the reliability of a ballast water treatment system is improved, the trouble removal time is shortened toa certain extent, and the trouble removal timeliness is improved to a certain extent.

Description

technical field [0001] The invention relates to a device for real-time monitoring and detection of water quality after treatment by ballast water equipment of ocean-going ships, in particular to a device for real-time monitoring and detection of ballast water quality of ships. Background technique [0002] On September 8, 2016, Finland ratified the "Ballast Water Management Convention" (BWM Convention), making the total merchant tonnage of the contracting parties reach 35.1441%, a total of 52 contracting parties, which means that the Convention has met its entry into force conditions - that is, it has gained a lot The Convention will enter into force on September 8, 2017, one year after ratification by at least 30 countries representing 35% of the world's merchant shipping tonnage. Under the International Convention for the Control and Management of Ships' Ballast Water and Sediments, ships will be required to manage their ballast water to remove, avoid pumping or dischargin...

AI Technical Summary

Problems solved by technology

[0003] Although a variety of ship ballast water treatment devices have been used on ships, since there is no real-time detection of ballast water treatment effects, the crew cannot detect whether the ballast water treatment system is working normally, and port state control can only Carrying water samples to land-based laboratories for testing

However, during the transportation of the sample, the sample may be damaged, and the microorganism may die, which will cause the measured data to be inaccurate

In addition, the Ballast Water Convention indicates that the port state cannot delay the ship's itinerary due to the failure to complete the inspection of the ship. Therefore, if the ship's berthing time is limited and the port state control cannot quickly obtain the information on the quality of the ship's ballast water, it cannot effectively monitor the ship. control

This creates certain problems for both the ship itself and port state control
