Abstract

The invention provides a control system of an ultraviolet sterilization device for treating ballast water. According to changes of flow and transmittance of ballast water and the cleanliness degree of the surfaces of lamp tubes, the intensity of ultraviolet lamp tubes can be automatically adjusted, so that the target output power required by sterilization is guaranteed, the service life of the ultraviolet lamp tube can also be prolonged, and meanwhile influences on a ship power distribution network can be reduced. The control system comprises the ultraviolet sterilization device, at least two ultraviolet lamp tubes are arranged in a shell of the ultraviolet sterilization device, an ultraviolet ballast is externally connected with each ultraviolet lamp tube, a control unit is externally connected with the ultraviolet ballasts, and a ship control system and a ballast water flowmeter are respectively externally connected with the control unit. The control system is characterized in that lamp tube cleaning units are arranged on sleeves of the ultraviolet lamp tubes respectively, the control unit is connected to the exteriors of the lamp tube cleaning units, an ultraviolet intensity detector is arranged on the outer wall of the shell of the ultraviolet sterilization device, and the control unit is externally connected with ultraviolet intensity detector.

Description

technical field [0001] The invention relates to the technical field of ballast water sterilization, in particular to a control system of an ultraviolet sterilizing device for ballast water treatment. The invention also provides a control method for the control system of an ultraviolet sterilizing device for ballast water treatment. Background technique [0002] Ships need to inject seawater into the ballast tanks for safe and stable navigation, and this part of seawater is usually called ballast water. The biggest problem of ballast water at present is that it will lead to the damage of exotic marine ecosystems by alien species. Therefore, the ship should be equipped with a ballast water treatment device, and the seawater needs to be treated with microbial inactivation. [0003] The ultraviolet sterilizing device is a part of the ballast water treatment system. Its sterilizing principle is to use the ultraviolet radiation emitted by the ultraviolet lamp to destroy the D...
