Sealing device for ultraviolet sterilization

Abstract

The invention discloses a sealing device for ultraviolet sterilization. The sealing device comprises an ultraviolet fluorescent tube and ultraviolet fluorescent tube installation seats disposed at two ends of the fluorescent tube. A quartz socket tube sleeves the ultraviolet fluorescent tube; and the quartz socket tube is fixed in the installation seats through fastening nuts. Quartz socket tube sealing gaskets are disposed between the quartz socket tube and the installation seats; sleeve type ceramic linings sleeve two ends of the ultraviolet fluorescent tube; the parts outside the ceramic linings are sealed by press covers; the press covers are fixed to the fastening nuts through bolts or screws; and openings at the middle of the press covers are provided with cable glands. The sealing device for ultraviolet sterilization is simple in structure and convenient for installation and replacement, and can realize replacement of a cleaning machine without taking the whole ultraviolet sterilization device out. Even if the quartz socket tube is broken, water can not flow out from the sealing device to destroy an electric system, thereby guaranteeing security of the whole system.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for an ultraviolet lamp tube. Background technique [0002] The ballast water of the ship contains different biological groups in various sea areas. If the microorganisms in the ballast water are not killed, the existing biosphere and biological chain will be seriously damaged with the discharge of the ballast water. Breed and some creatures will be endangered. [0003] Ultraviolet sterilization is often used for sterilization and disinfection of water bodies, and good results have been obtained. In the field of ship ballast water treatment, it is simple and easy to use ultraviolet lamps to sterilize ballast water, and the sterilization effect is good. However, since the sterilization of ballast water is carried out in the water body, the sealing problem of the ultraviolet lamp becomes a problem that must be solved at present. The existing ultraviolet sterilizing sealing de...

AI Technical Summary

Problems solved by technology

However, since the sterilization of ballast water is carried out in the water body, the sealing problem of the ultraviolet lamp becomes a problem that must be solved at present.

The existing ultraviolet sterilizing sealing device is to seal the ultraviolet lamp as a whole. When cleaning and replacing the ultraviolet lamp tube, the whole device needs to be taken out. During this time, the ultraviolet sterilizing device needs to be stopped, which will affect the treatment of ballast water, especially When the ship is berthing or leaving the wharf or when the ship is loading and unloading, etc., when the ballast water needs to be treated urgently, if the ultraviolet sterilization device fails, the quality of the ballast water cannot be guaranteed.
