Embodiment 1

[0027] Embodiment 1: with reference to attached figure 1 to attach image 3 As shown, the LED ultraviolet fluid disinfection device described in this embodiment is mainly composed of a circular protective shell 2, an LED ultraviolet disinfection assembly 1 and a spiral sleeve 4 of a fluid passage. Wherein, the inner wall of the protective shell 2 is provided with an ultraviolet reflective layer 3, and the LED ultraviolet disinfection assembly 1 is inserted into the middle of the spiral sleeve 4 for disinfection. The LED disinfection assembly 1 is composed of a circular support 10 made of flexible printed circuit and an ultraviolet LED module 12 equipped with an integrated high power density ultraviolet LED light source 11 . The shape of the outer edge of the support member 10 is circular, which can ensure that the ultraviolet LED module 12 can uniformly and efficiently disinfect the fluids to be disinfected in all directions, such as water, etc., and the inner wall of the cir...

Embodiment 2

[0030] Embodiment 2: with reference to attached Figure 4 to attach Image 6 As shown, the difference from Embodiment 1 is that the support member 10 of this embodiment adopts a rigid printed circuit structure and its outer edge shape is hexagonal.

[0031] as attached Figure 4 And attached Figure 7As shown, this disinfection device can also be equipped with an ultraviolet radiation intensity detection probe 6, and the change of the ultraviolet radiation intensity of the disinfection device ultraviolet radiation intensity detection probe 6 detected by the control circuit (the change of the ultraviolet radiation intensity may be caused by the change of the water supply pressure) Changes in the flow rate may also be caused by changes in the water quality of the water supply) to intelligently control the number of LED modules 12 turned on to achieve its intelligent control, so as to reduce the number of LEDs used as much as possible under the condition of sufficient disinfect...

Abstract

The invention provides a light-emitting diode (LED) ultraviolet fluid disinfection method and a device thereof, wherein disinfection is realize by adopting an LED disinfection component, the LED disinfection component utilizes an integrated high-power density ultraviolet LED light source, so the ultraviolet radiation illumination intensity of a disinfection space is improved to 5-60mW / cm[2]; and a fluid pipeline adopts a bending pipeline, the ultraviolet radiation time is controlled between 0.2-2.5s according to the fluid velocity, so the fluid ultraviolet radiation dose which passes by the pipeline is ensured to be larger than 15mJ / cm[2] (mW.s / cm[2]), the bacteria and virus are killed at one time, and the odour is removed. The disinfection device has the advantages of high efficiency, quickness, small size and multiple functions. The invention can be used for disinfecting the drinking water, milk, soyabean milk and various fluids of hotels, shopping malls, factories, office buildings and other public places or homes and other occasions.

Description

technical field [0001] The invention relates to the field of ultraviolet disinfection technology, in particular to a LED ultraviolet fluid disinfection method and a device thereof. Background technique [0002] With the improvement of people's living standards and the increasing pressure of environmental pollution, people's demand for disinfection and sterilization of various items, drinking water and space is increasing. In addition to various chemical disinfection, ultraviolet rays can kill most bacteria and virus microorganisms, with fast sterilization, high efficiency, no toxic side effects, low operation and maintenance costs, and more and more applications in the field of disinfection. application. [0003] Traditional ultraviolet lamps mainly rely on the stimulation of metal mercury atoms to generate 253.7nm ultraviolet rays for disinfection. Mercury is poisonous. In order to avoid the pollution caused by mercury to the sterilized substance or environment caused by ...
