Description
P1064 /NL LARGE-CALIBER OVERFLOWING TYPE WATER PURIFICATION AND DISINFECTION
TECHNICAL FIELD The disclosure relates to the technical field of water puri- fication, in particular to a large-caliber overflowing type water purification and disinfection apparatus.
BACKGROUND ART Water is essential matter for production and living of peo- ple, purification of water becomes more and more important, and thus it is especially important to disinfect a water body. After the water body is coagulated or filtered, although microorganisms in the water body are greatly reduced, they are still not inacti- vated completely. In the prior art, domestic water is generally disinfected through the following means: 1, physical methods such as ultrasonic disinfection and a heating method; and 2, chemical methods: a chlorination method, an ozone method, a heavy metal ion method and other oxidant methods. But action ranges of the heating method and the ultrasonic disinfection are limited, and adverse effects such as toxicity of water, dangerousness of organochlorine and agent resistance of viruses and protists to chlorine are gen- erated to the environment by chemical matter in the chemical meth- ods. By contrast, water is purified in an ultraviolet disinfection manner, especially deep ultraviolet disinfection receives atten- tion of people due to its good effect and no generation of disin- fection byproducts. A dynamic direct drinking water deep ultraviolet LED steri- lizer with the publication number of CN104016443 B discloses a dy- namic direct drinking water deep ultraviolet LED sterilizer, com- prising a water inflow assembly, a water outflow assembly, a dis- infection and sterilization assembly and a deep ultraviolet LED module, deep ultraviolet LEDs are adopted as luminous sources, point location area light irradiated by the deep ultraviolet LED module is high in intensity and free of toxic materials, and dy- namic water is efficiently disinfected and sterilized; and an ul-
traviolet LED fluid disinfection system with the publication num- ber of CN103570098 A discloses an efficient fluid disinfection treatment system integrated with a deep ultraviolet LED chip, as for the defects that ultraviolet spectrum radiation distribution is not uniform, and the effect of the deep ultraviolet LED chip is reduced, a deep ultraviolet LED assembly is adopted, ultraviolet light with an efficient disinfection function is generated, the ultraviolet light can effectively penetrate through a transparent pipeline and disinfect fluid in the transparent pipeline, the in- ner and outer surfaces of the pipeline are coated with a reflec- tive material with an ultraviolet light reflecting function, and thus the ultraviolet light emitted by deep ultraviolet LEDs and transmitted out is reflected back into the pipeline. A flowing fluid disinfection method and a disinfector with the publication number of CN109395118 A disclose a flowing fluid disinfection method adopting deep ultraviolet light rays and a disinfector achieving flowing fluid disinfection, as for the defects that in an existing fluid disinfection technology, UV energy loss is gen- erated due to a solid-liquid surface between to-be-disinfected fluid and a device containing the fluid, a flowing fluid column with the side wall wrapped by a fluid medium and in contact with the fluid medium is generated, ultraviolet light is emitted into the flowing fluid column in an axial direction, the UV energy loss is reduced, and the disinfection effects of the flowing fluid such as water, drinks or medical fluid is improved.
However, it is found in practice that when an ultraviolet water purification technology is adopted for treating large-flow fluid, if radiation sources perform single area disinfection, that is, the whole area is disinfected through the radiation sources, the setting cannot achieve disinfection treatment of the large- flow fluid. In order to solve the above problems, it is necessary to provide a new technical means.
SUMMARY In order to overcome the defects in the prior art, the dis- closure provides a large-caliber overflowing type water purifica- tion and disinfection apparatus.
The technical solution adopted for solving the technical problems of the disclosure is as follows: the disclosure provides the large-caliber overflowing type water purification and disin- fection apparatus, comprising a reactor cavity in a straight line shape extending in a front-and-back direction, wherein a water in- let and a water outlet are formed in the front side and the back side of the reactor cavity respectively; lens sets are disposed on the inner wall of the reactor cavity, and radiation assemblies are disposed between the inner wall of the reactor cavity and the lens sets; and each lens set comprises a fly-eye lens.
According to the large-caliber overflowing type water purifi- cation and disinfection apparatus provided by the disclosure, through the cooperation of the radiation assemblies and the lens sets, a uniform rectangular light spot is formed to transmit into the reactor cavity, sterilization and water purification effects are better, and the functions of ultraviolet light uniform disin- fection and water purification in the large-space and large-flow reactor cavity are achieved.
As some preferred embodiments of the disclosure, each fly-eye lens comprises an inner-layer fly-eye lens and an outer-layer fly- eye lens.
As some preferred embodiments of the disclosure, each lens set comprises a collimating lens, and the collimating lenses face one sides of the radiation assemblies.

As some preferred embodiments of the disclosure, each radia- tion assembly comprises a deep ultraviolet UVC-LED with a waveband of 200-280 nm.
As some preferred embodiments of the disclosure, mounting shells are disposed on the inner side of the reactor cavity, and the lens sets and the radiation assemblies are connected with the mounting shells.
As some preferred embodiments of the disclosure, grooves are formed in the mounting shells, and the lens sets and the radiation assemblies are disposed in the grooves.
As some preferred embodiments of the disclosure, the lens sets are spliced together through a resin material and mounted in the grooves, and the radiation assemblies are spliced together through the resin material and mounted in the grooves. As some preferred embodiments of the disclosure, a reflective coating is disposed on the inner side of the reactor cavity. As some preferred embodiments of the disclosure, a protective sleeve is disposed on the outer side of the reactor cavity. The present disclosure has the following beneficial effects: 1, in the new apparatus, the lens sets are adopted for light homogenization at emergent light rays of the radiation assemblies, and compared with traditional direct light source irradiation dis- infection, the new apparatus can provide more uniform disinfection radiation fields, so that disinfection is complete; 2, in the new apparatus, prismatic light fields formed by a plurality of rectangular light spots can be transversely and lon- gitudinally spliced into a large-area and large-space uniform prismatic light field, and compared with a traditional cylindrical or conical light field formed by round light spots, the round light spots are hardly spliced into a uniform large light spot, so that intensity distribution of the light field is uneven; and 3, in the new apparatus, the inner cavity similar to a straight line is adopted as a main disinfection and water purifi- cation carrier, the inner cavity can cooperate with the large- caliber water inlet and the large-caliber water outlet, and com- pared with a traditional disinfection device that a water inlet and a water outlet are generally small to control a flow rate, the new apparatus has a higher water flow rate.

DETAILED DESCRIPTION OF THE EMBODIMENTS 5 In order to make the objectives, technical solutions and ad- vantages of the disclosure more clear and understandable, the dis- closure is further illustrated in detail below with reference to accompanying drawings and implementations. In order to thoroughly understand the disclosure, some specific details will be involved in the following descriptions. The disclosure still can be achieved without these specific details, and those skilled in the art can more effectively introduce their work nature to other those skilled in the art by using these descriptions and state- ments here. In addition, it shall be noted that words ‘front side’, ‘back side’, ‘upper side’, ‘lower side’, etc. used in the following descriptions refer to directions in the accompanying drawings, words ‘inner’ and ‘outer’ refer to directions facing or facing away from geometric centers of specific components respec- tively, and simple and non-creative adjustment made by related technical personnel for the above directions shall not be under- stood as technologies beyond the protection scope of the disclo- sure. It shall be understood that the specific implementations de- scribed here are only used for explaining the disclosure instead of limiting the actual protection scope. In order to avoid confu- sion of the objectives of the disclosure, as known fabrication methods, control programs, component sizes, material components, pipeline layout and other technologies have been easily under- stood, they are not described in detail.
FIG. 1 is a structural schematic diagram of an implementation of the disclosure, referring to FIG. 1, the implementation of the disclosure provides a large-caliber overflowing type water purifi- cation and disinfection apparatus, comprising a reactor cavity 100 in a straight line shape extending in a front-and-back direction, wherein a water inlet 101 and a water outlet 102 are formed in the front side and the back side of the reactor cavity 100 respective- ly. The reactor cavity 100 is of a relatively-sealed structure, and water enters the reactor cavity 100 from the water inlet 101 and then goes out of the reactor cavity from the water outlet 102.
Furthermore, lens sets 200 are disposed on the inner wall of the reactor cavity 100, and radiation assemblies 300 are disposed between the inner wall of the reactor cavity 100 and the lens sets
200. The radiation assemblies 300 emit ultraviolet light for ster- ilization and purification work. The sterilization principle of the ultraviolet light is as follows: based on absorption of micro- organism nucleic acid for the ultraviolet light, when microorgan- isms are irradiated by the ultraviolet light, DNA (deoxyribonucle- ic acid) and RNA (ribonucleic acid) molecular structures of the microorganisms will be damaged as they absorb energy of the ultra- violet light, growth cells and regenerative cells die, the micro- organisms are inactivated to lose the functions of propagation and self-replication, and the effects of sterilization and disinfec- tion are achieved.
Furthermore, referring to FIG. 2, each lens set 200 comprises a fly-eye lens 210. Radiation light emitted by the radiation as- semblies 300 is uniformly projected into the reactor cavity 100 through the lens sets 200. The fly-eye lenses 210 are in charge of homogenizing the ultraviolet light, the specific structure and working principle can refer to those of an existing fly-eye lens apparatus, and re-description is omitted here.
The radiation assemblies 300 and the lens sets 200 may be in- tegrated, and also may be spliced by a plurality of parts, and the specific condition is decided according to the shape of the reac- tor cavity 100.

In the embodiment, preferably, the resin material is a CYTOP resin material, as unique resin resistant to deep ultraviolet, the CYTOP resin material has good transmissivity from deep ultraviclet to far infrared wavebands, and especially the transmissivity in UV 250 nm-400 nm wavebands can reach 100%. Embodiment 11: a reflective coating is disposed on the inner side of the reactor cavity 100. Embodiment 12: a protective sleeve 110 is disposed on the outer side of the reactor cavity 100 and configured to protect and support structures in the apparatus.
In the embodiment, optionally, the protective sleeve 110 is a prismoid or a cylinder.
In the embodiment 12, referring to FIG. 3, each lens set 200 sequentially comprises the collimating lens 220, the outer-layer fly-eye lens 212, the inner-layer fly-eye lens 211 and the col- lecting lens 230 from the outer side of the reactor cavity 100 to the inner side of the reactor cavity 100, that is, the collimating lenses 220 are closer to the radiation assemblies 300. Light emitted by the radiation assemblies 300 is adjusted by the lens sets 200, when the radiation light emitted by the radia- tion assemblies 300 is collimated by the collimating lenses 220 and then radiated to the outer-layer fly-eye lenses 212, radiation light beams are focused to centers of the inner-layer fly-eye lenses 211 by the outer-layer fly-eye lenses 212, that is, the ra- diation light emitted by the radiation assemblies 300 is gathered and then divided into a plurality of small radiation sources by the outer-layer fly-eye lenses 212 to be emitted, the radiation light emitted by small lenses corresponding to the outer-layer fly-eye lenses 212 is overlapped, homogenized and dispersed by each small lens of the inner-layer fly-eye lenses 211, and the ra- diation light emitted, homogenized and dispersed by the inner- layer fly-eye lenses 211 is focused in a quartz cavity (inner cav- ity) of the reactor cavity 100 by the collecting lenses 230. Seen from FIG. 3, whole wide light beams of the radiation assemblies 300 can be divided into a plurality of thin light beams by the outer-layer fly-eye lenses 212 to be radiated, tiny nonuniformity of the thin light beams within each thin light beam range is well compensated for due to mutual overlapping of the thin light beams at symmetric positions, and radiation energy within the whole hole diameter spatial range is effectively homogenized.
Meanwhile, as the radiation light emitted by the inner-layer fly-eye lenses 211 is focused into the quartz cavity (inner cavity) of the reactor cavity 100 by the collecting lenses 230, each point within the ra- diation area range can receive more radiation light, meanwhile, the radiation light emitted by each point on the radiation assem- blies 300 is overlapped within the same range on the radiation ar- ea, a uniform rectangular radiation area is obtained, and finally a prismatic light field is formed in the quartz cavity (inner cav- ity) by the radiation light.
According to the above principle, the disclosure also can properly change and modify the above implementations.
Thus, the disclosure is not limited to the specific implementations dis- closed and described above, and some modifications and changes of the disclosure also shall fall into the protection scope of the claims of the disclosure.
