Problems solved by technology
Its disadvantages are: 1. The independent processing units are connected with each other by pipes, which reduces the space utilization rate of the system, increases the space occupation, and increases the resistance loss of the system
2. The downstream setting of the ultraviolet lamp tube is beneficial to the distribution of the liquid flow field, but there is an uneven distribution of the light field, which is not conducive to the reasonable distribution of the ultraviolet radiation dose; the cross-flow setting of the ultraviolet lamp tube is beneficial to the comprehensive ultraviolet radiation dose. The improvement of the distribution is beneficial, but because of the influence of the cavity section change factor on the flow velocity of the section medium, the coupling requirements for the optical field are increased, which is not conducive to the scaling of the system

Embodiment
[0025] Such as figure 2 As shown, it is a structural schematic diagram of an integrated ship ballast water treatment device. The integrated ship ballast water treatment device includes a cylindrical container 1, and the inside of the cylindrical container 1 is divided into a cross-section by an intermediate partition plate 2. The circular filter unit chamber and the ultraviolet disinfection unit chamber with a ring-shaped section are located outside the filter unit chamber, and the center of the circular section of the filter unit chamber and the annular section of the ultraviolet disinfection unit chamber are located The centers of the circles coincide. The present invention combines the filter unit chamber and the ultraviolet disinfection unit chamber in the same cylindrical container.
[0026] The middle partition plate 2 is provided with a ballast hole, the filter unit chamber is provided with a circular filter screen 3, one end of the cylindrical container 1 is provided...

The invention provides an integrated ship ballast water treatment device, comprising a cylindrical container, characterized in that the cylindrical container is divided into a filter unit chamber with a circular cross-section and a cross-section of An annular ultraviolet disinfection unit chamber, the ultraviolet disinfection unit chamber is located outside the filter unit chamber, ballast holes are provided on the middle partition plate, filter screens are provided in the filter unit chamber, and the ultraviolet A treated water outlet is provided on the outer wall of the disinfection unit chamber. The invention adopts an integrated structure, has extremely high space and plane utilization rate, occupies small space and plane size, saves pipeline connection, and has smaller system resistance.
Description
technical field [0001] The invention relates to an integrated ship ballast water treatment device. Background technique [0002] Ballast water treatment using filtration + ultraviolet disinfection has become a typical process for ship ballast water treatment. It has the advantages of pure physics, no toxic side effects, obvious treatment effect, suitable for both seawater and freshwater environments, no secondary pollution, safe and reliable, easy to operate, etc., and has attracted widespread attention from the market and users. For the ship's ballast water treatment system, its notable features should include large flow, limited space, environmental adaptability requirements, and meet the specified discharge standards. [0003] Such as figure 1 As shown, the existing filtration+ultraviolet method ballast water treatment device system includes a filtration unit 1-1, an ultraviolet disinfection unit 1-2, an external pipeline 1-3, a filter screen 1-4, an ultraviolet lamp 1-...
