Abstract: A collimation type disinfection and water purification device includes a reactor cavity. The reactor cavity is in a linear shape extending in a front side direction and a rear side direction. A water inlet and a water outlet are respectively formed in side walls of a front side and a rear side of the reactor cavity. Ultraviolet (UV) modules are arranged at end parts of the reactor cavity. The UV module includes a radiation component and a Total Internal Reflection (TIR) lens. The radiated UV light can enter the reactor cavity in a collimation manner by using a design that the radiation component is matched with the TIR lens, which improves the disinfection efficiency.
