Description

Ballast water cyclone separator

Technical Field

The utility model relates to the technical field of ballast water treatment, in particular to a cyclone separator for ballast water.

Background

According to International Maritime Organization (IMO) statistics, over 80% of the world's cargo is transported by ships. Thus, over 100 million tons of ballast water move with the cargo each year.

To ensure safe marine travel of a fully or partially fully loaded vessel, the vessel, when unloaded at a port, typically injects seawater into ballast tanks that may often introduce local marine species (e.g., bacteria and multicellular species) into the ballast water. When the ship arrives at the next port, the ballast water must be pumped out. If the water contains living organisms, it may cause the following biological pollution to the marine environment of the port.

All modern ships integrate ballast water devices including pumps, filters, pipes, ventilation and storage tanks. The ballast tanks may be located between the hulls of a sandwich bulkhead vessel, or any other suitable tank for the purpose. When ships are completely or partially unloaded at one port, they will travel to other ports to load other cargo. When the vessel returns with empty or partially empty cargo or storage tanks, water may be used to fill the ballast tanks to ensure stable sailing and adequate submersion of the propellers and rudders, and to achieve reasonable vessel trim and/or to ensure that structural limitations of the vessel's structural integrity are not exceeded. The ballast tanks are typically filled with seawater at the discharge and supply ports. When the ship arrives at a new loading port, the ballast water must be discharged into the surrounding sea area.

Worldwide distribution of ballast water has raised concerns about its environmental impact. When port water is used for ballast tanks, the water may contain a large number of representative organisms for the port, which may be seaweeds, algae, fish larvae, fish, mollusks or other living organisms, various parasites, bacteria, viruses, and the like. When water is discharged at other ports, these organisms may find their unoccupied niches in the biological system and begin to reproduce without a natural enemy threat. It is well known that foreign animal and plant species pose serious problems for local ecology. Approximately 7000 marine organisms and microorganisms are brought around the world and attach to the hull and ship ballast water. To prevent harmful damage by pests, maritime organizations have passed international treaty on the control and management of ship ballast water and sediments, 2-13.2004. In addition to ballast exchange in open sea (open sea), filtration is the most common and simplest method of reducing pest concentrations. Most commercial ships use a 15mm filter screen or the like at the sea chest, which can only remove larger organisms such as fish, invertebrates and macrophytes, and can not completely remove some fine particles, the filter screen can be blocked after being used for a period of time, frequent shutdown maintenance is required, the safety and economy are poor, and some bacteria, viruses, fungi, protozoa, plankton or ovum and larvae in higher life forms can also exist in ballast water, and the filter screen can not treat the larvae.

Disclosure of Invention

In order to solve the problems that the existing ballast water treatment effect is poor, the safety and the economy are low, and bacteria, viruses, fungi and the like cannot be treated, the utility model provides a ballast water cyclone separator which can effectively improve the ballast water treatment effect and improve the safety and the economy.

The technical scheme is as follows: the utility model provides a ballast water cyclone, its includes the separator casing, its characterized in that, the separator casing includes barrel and lower cone, install both ends open-ended vortex stand pipe in the separator casing, vortex stand pipe lower part is located down in the cone and global the through-hole of being the array and arranging is seted up, vortex stand pipe upper portion is located go up barrel and outer peripheral face and install the negative plate, go up barrel inner wall install with negative plate complex anode plate, vortex stand pipe top connection is located the outside outlet pipe of separator casing, the cone bottom is the outlet down, go up barrel outside lateral wall and connect tangent inlet tube.

The top of the vortex guide pipe is connected with the water outlet pipe through a sealing element;

the water outlet pipe, the water outlet and the water inlet pipe are all provided with flanges.

After the utility model is adopted, ballast water flows into the upper cylinder body from the water inlet pipe, rotates in the upper cylinder body and then enters the lower cone body, when the upper cylinder body rotates, water electrolysis and disinfection of the ballast water are realized due to the existence of the cathode plate and the anode plate, bacteria, viruses, fungi and the like in the ballast water are killed, the ballast water can reversely rotate and rise to enter the vortex guide pipe under the dual actions of centrifugal force and the inclined surface of the lower cone body after reaching the lower cone body, and impurities with specific gravity larger than that of the water can fall down and be discharged from the water outlet at the bottom of the lower cone body, so that the ballast water treatment effect is effectively improved, the phenomena of blockage and the like can not occur, and the safety and the economical efficiency are good.

FIG. 2 is a top view of the present invention.

Detailed Description

See fig. 1, as shown in fig. 2, a ballast water cyclone separator, which comprises a separator shell, the separator shell comprises an upper cylinder 1 and a lower cylinder 2, a vortex guide pipe 3 with two open ends is installed in the separator shell, the lower part of the vortex guide pipe 3 is located in the lower cylinder 2 and is provided with through holes 4 arranged in an array manner on the circumferential surface, the upper part of the vortex guide pipe 3 is located in the upper cylinder 1, and the outer circumferential surface of the vortex guide pipe is provided with a cathode plate 5, the inner wall of the upper cylinder 1 is provided with an anode plate 6 matched with the cathode plate 5, the top of the vortex guide pipe 3 is connected with a water outlet pipe 8 located outside the separator shell through a sealing element 7, the bottom of the lower cylinder 2 is a water outlet, the outer side wall of the upper cylinder 1 is connected with a tangential water inlet pipe 9, and ballast water entering the upper cylinder 1 can rotate. The water outlet pipe 8, the water outlet and the water inlet pipe 9 are all provided with flanges 10, so that the connection is convenient.

The working principle is as follows: ballast water with impurities, microorganisms and the like enters the separator shell from the water inlet pipe 9, reaches the upper cylinder 1 firstly, rotates around the vortex guide pipe in the upper cylinder and moves downwards due to the cathode plate 5 and the anodeThe existence of the polar plate 6 can electrolyze the ballast water, and Cl is generated in the process of electrolysis₂Active species including HOCl, OCl-and OH-radicals. Due to the synergistic effect of the active substances, bacteria, yeast, viruses, molds, spores, algae, protozoa, zooplankton, phytoplankton, larval stages, fish eggs and other microorganisms which cannot be removed through filtration in the ballast water can be effectively killed, the electrolyzed ballast water rotates to enter the lower cone 2, and under the action of centrifugal force and the action of the inclined plane of the inner wall of the lower cone 2, the ballast water can reversely rotate to enter the vortex guide pipe 3 and is finally sent out from the water outlet pipe 8 to obtain the treated ballast water, and impurities with specific gravity larger than that of water fall along the inner wall of the lower cone 2 and are finally discharged from the water outlet at the bottom. Be the through-hole 4 that the array was arranged on the vortex stand pipe 3, the through-hole 4 that this array was arranged has effectually increased area of contact between liquid medium and the metal, and then has improved anodic oxidation reaction effect, and liquid need get into water cyclone's delivery port through this through-hole 4 that really arranges simultaneously, and then has also controlled cyclone's separation precision.
