Embodiment

[0023] The ultraviolet lamp of this device is installed in the quartz casing through the elastic positioning sleeve, and the elastic positioning sleeve is processed by polytetrafluoroethylene. One end is a hemispherical structure, and the other end is a groove structure. In order to ensure the installation position of the UV lamp, a through hole is designed at the bottom of the elastic positioning sleeve to discharge the residual air between the UV lamp and the elastic positioning sleeve.

[0024] The sealing of the ultraviolet lamp is realized based on the left and right flanges. The quartz tube sealing sleeve is designed with a shaft shoulder, an inclined plane and a lip-shaped gap. The left end seal is realized by pressing the quartz tube sealing sleeve and the quartz sleeve through the left gland using the shaft shoulder and the inclined plane. When there is a certain water pressure in the ballast water, the lip-shaped notch design makes the sealing sleeve of the quartz tu...

Description

technical field [0001] The invention relates to an ultraviolet lamp sealing and fixing device for a ship ballast water treatment system. Background technique [0002] Species invasion caused by ship's ballast water poses a great threat to the global marine ecological environment. In order to effectively control the damage caused by ship's ballast water discharge to the marine ecological environment, ballast water treatment system came into being. [0003] Among various ballast water treatment technologies, ultraviolet sterilization technology has been widely used due to its unique advantages of high efficiency, spectrum and no secondary pollution. In the ultraviolet sterilization system, the ultraviolet lamp should be completely submerged in water, so the requirements for sealing and fixing the ultraviolet lamp are very high. At present, the commonly used sealing methods for ultraviolet lamps are mostly sealed by O-rings, which have poor sealing effect and poor water pressu...
