| 简介 |
The present invention pro-vides an apparatus and method for accomplishing fluid disinfec-tion by passing fluid flow through a uniform array (3B) of ultraviolet lamps having cross sections per-pendicular to the direction of fluid flow that define channels (8) for the fluid flow. Positioned next to the end of each lamp (5) at the entrance of the fluid flow are tri-angular shaped delta wings hav-ing surfaces inclined at an an-gle to the direction of fluid flow.
The interaction of the fluid flow with each delta wing creates a pair of vortices (10) that rotate in the same direction or indirec-tions opposed to each other. The counter-rotating vortices (10) rein-force each other to minimize dissi-pation of their mixing strength as they move down the channel (8).
Due to these co-reinforcingprop-erties these counter-rotating vor-tices (10) more promote efficient mixing of the fluid which is re-quired to achieve more efficient use of the light in the UV disin-fection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired. |
