Description

Ballast water ultraviolet treatment device for ship
Technical Field
The invention belongs to the technical field of ballast water treatment, and particularly relates to an ultraviolet treatment device for ballast water for a ship.
Background
The ballast water of the ship is ballast carried by the ship for stable balance of the ship when the ship is offshore, the tonnage is vacated when the ship arrives at the shore, the ballast water is required to be discharged into a sea area of a shore country, and the invasion of foreign organisms caused by the discharge of the ballast water of the ship becomes a main path for the spread of harmful organisms in the sea. In 2004, the international maritime organization "international convention on the control and management of ballast water and sediments in ships" stipulates that ballast water treatment facilities must be installed in newly constructed ships.
The ultraviolet inactivation technology is widely applied to ballast water treatment due to the characteristics of no environmental pollution, no need of using extra consumables, compact structure and the like. However, because the ship ballast water flow is large and the residence time is short, when the ship ballast water flows through the ultraviolet treatment device, the ship ballast water is limited by the flow rate, the luminous arc length of the ultraviolet lamp tube and the ultraviolet irradiation distance of the UVC wave band, a flow field blind area which cannot be irradiated easily occurs, and partial water flow containing plankton directly flows out of the ultraviolet treatment device without effective treatment. In addition, due to the limitation of ship space, the volume of the device is limited, so that the time of ballast water flowing through the ultraviolet treatment device is shorter, and a flow field blind area is easier to appear.
At present, most of ballast water ultraviolet treatment devices for ships adopt low-pressure ultraviolet tubes, the low-pressure ultraviolet tubes are low in power density, single in spectrum and long in size, the number of the required tubes is large under the same dosage, and the ballast water ultraviolet treatment devices are inconvenient to use. Meanwhile, the single spectrum has limitation on killing of complex phytoplankton in ballast water. The medium-pressure ultraviolet lamp tube is mostly designed in an L shape or a square shape in the ultraviolet treatment device of ballast water for ships, and the product can only be vertically installed, so that the application space is limited.
