No-clean UV sterilization device for secondary water supply

The invention relates to a no-clean UV sterilization device for secondary water supply, which comprises a shell; a turbulence generator and a sterilization assembly which are arranged in the shell, wherein the turbulence generator is connected with the shell and arranged at one end of the sterilization assembly. By adding the turbulence generator, water flow flowing through the UV sterilization device generates turbulence. Turbulence is beneficial to carrying of impurities in water, so that the impurities do not sink or are difficult to deposit on the quartz sleeve, and no-clean of the UV sterilization device is further realized. 本发明涉及一种用于二次供水的免清洗UV杀菌装置，包括壳体，所述壳体内部设置有紊流发生器和杀菌组件，所述紊流发生器与壳体连接，且设置在杀菌组件的一端。通过加入紊流发生器，使流经UV杀菌装置的水流产生紊流。紊流有利于水中杂质的搬运，使其不沉或者较难沉积在石英套管上，进而实现了UV杀菌装置的免清洗。
