Top side tank ballast water mechanical energy recovery and utilization system

Abstract

The invention provides a top side tank ballast water mechanical energy recovery and utilization system. The system comprises a drainage system, a water inlet system and a power generation system. Whenballast water needs to be discharged from a ship, potential energy in the ballast water of a top side cabin is recycled by utilizing the height advantage of the top side cabin of the ship, the loss of ship energy is reduced, and meanwhile, mechanical energy contained in the ballast water of the top side cabin of the ship is converted into electric energy to supply power to part of lamp tubes in an ultraviolet treatment device, the power consumption of the ultraviolet treatment device to the ship is reduced, the load of a ship power grid can be effectively reduced, in addition, electric energygenerated in the system can be directly supplied to part of ultraviolet lamp tubes for direct use through a rectification and voltage regulation device, intermediate processes such as storage in a storage battery are not needed, and the intermediate energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a system for recovering and utilizing mechanical energy of ballast water in topside tanks. Background technique [0002] At present, with the needs of cargo transportation, the types of ships have become more diverse. Cargo ships alone include general cargo ships, bulk carriers, container ships, ro-ro ships, barges, oil tankers, liquefied gas carriers, refrigerated ships, etc. . Among them, due to the particularity of bulk carrier transportation, most of them sail empty when returning. For example, the ore ship in the bulk carrier only exists near the loading port, so when the ore ship arrives at the unloading port and returns , Usually no cargo is loaded, that is, sailing empty. However, the normal navigation of the ship needs to maintain a certain draft to avoid the ship's center of gravity being too high and prone to capsizing. At the same time, the draft of the sh...

Problems solved by technology

However, in the process of ballast water treatment, the higher the degree of ultraviolet radiation, the better the bactericidal effect. Therefore, in the ballast water treatment system, in order to achieve a better treatment effect, the power of the ultraviolet lamp can reach hundreds of kilowatts, which will Consume a lot of precious ship power
