Abstract:
1. A fluid UV sterilization system comprising an electrical controller, a channel, a UV lamp module group consisting of one or more UV lamp module(s), each UV lamp module comprising a frame and a plurality of UV lamps mounted on the frame; the channel being provided with a fluid level control device, characterized in that the orientation of the frame of each UV lamp module is perpendicular to or parallel to or forms an angle with the general flow direction in the channel; a baffle is provided on either the upstream or both the upstream and downstream of at least one of the UV lamp module(s), the top of the baffle is higher than the effective radiation distance of the UV lamp module group towards the fluid surface, and the bottom of the baffle extends to such an extent towards the bottom of the channel that it at least reaches within the effective radiation distance of the UV lamp module group towards the fluid surface, and the projected width of the baffle on the channel section perpendicular to the general flow direction on the upstream of the baffle is equal to the internal width of the channel at a place where the baffle is located.
