Description
Technical field
The present invention relates to the ballast water processing and the device of boats and ships, be specifically related to a kind of ocean vessel ballast water processing and special processor thereof.
Background technology
At present, ship is a ring important in the global logistics chain, and 80% above goods is through the boats and ships transhipment in the international trade.Oceangoing vessel causes that the territory over strait of unwanted aquatic organism and pathogenic agent is propagated when injecting and discharging water ballast.The nothing control discharging of water ballast causes serious harm to marine ecology, public health, and the marine ecology malicious event that causes thus is too numerous to enumerate, and global environmental protection foundation (GEF) classifies them one of as ocean four big harm.
In order to control and prevent the alien species invasion that the ballast water for ship discharging causes effectively, the environment that pathogen propagation causes, human health, property and the infringement of resource aspect.International Maritime Organizaton (IMO) has passed through " international shipping water ballast and settling control and management contract " (hereinafter to be referred as the water ballast pact) in 2004.This pact is that global Ballast Management provides the regulation with international law restraint force with control.
Along with the appearance of water ballast pact, a lot of harbour states have successively taked corresponding monolateral policy, and the measure of mandatory enforcement Ballast Management is to reduce the harm that water ballast brings local waters.The Ballast Management method generally can be divided into two types: preventative operation and special operation response.Preventative operation mainly is that water ballast is isolated; Promptly take not discharge; Take back the original place or enter the methods such as special receiving trap at purpose harbour, thereby avoid drawing aquatic organism, pathogenic agent or the settling of potential hazard as far as possible, and avoid unnecessary discharging.Special operation response can be divided into water ballast exchange and two kinds of methods of ballast water treatment.
At present, most harbour state has all adopted the method for deep sea ballast water exchange to carry out Ballast Management to the entrained water ballast of the boats and ships that sail local waters into.Can select different water ballast switching methods for use according to the particular case of boats and ships, concrete grammar has sequential method, dilution method and press over system.Sequential method is also claimed the emptying injection method, and the ballast tank that promptly will be used to load water ballast earlier finds time to refill with the water ballast of replacement then, is at least 95% of water ballast volume to reach rate of displacement; Use sequential method; Almost by displacement completely effectively, the ballast pump load is little for water ballast, and swap time is short.But possibly influence the structural strength of boats and ships.To carry out safety assessment to make rational water ballast exchanger to aspects such as the longitudinal strength of hull and intact stabilities.Dilution method is meant that the water ballast with replacement injects from the water ballast tank top that is used to load water ballast and discharges from the bottom with identical flow velocity simultaneously; Water level in the cabin remains unchanged in ballast water exchange operation whole process; When adopting dilution method and press over system, each ballast tank is continuously pumped into the water yield and reaches three times of volume of compartments and can be considered the standard-required that meets the water ballast that exchanges 95% volume at least.If can prove the water ballast that has exchanged 95% volume at least then can accept the continuous pump water yield and be less than three times of volume of compartments.The triple exchange water yield, the load of ballast pump is big, and swap time is long; But because ballast tank always is in full cabin state; Therefore these two kinds of switching methods can be ignored the stability of boats and ships and the influence of intensity, pump into the bottom and pump water ballast because dilution method needs two cover pumps systems to carry out the top separately, and need to keep the flow velocity that pumps into and pump equal; Thereby keep the pressure in the cabin constant to keep in the cabin water level to remain unchanged, piping is comparatively complicated.Existing ship does not generally adopt this kind switching method.Press over system is meant that the water ballast with replacement pumps into the ballast tank that is used to load water ballast, and allows water to flow out from riser or other devices.When adopting press over system; If the overflow device overflow is insufficient, ballast tank just has the danger of superpressure, therefore will assess the total cross-sectional area and the pipe resistance of overflow passage; But because press over system is very little to the influence of the intensity of boats and ships and stability, therefore to some greatly ballast tanks should adopt.
