Collimated beam apparatus

Abstract

The invention discloses a collimated beam apparatus which comprises a box body, at least two partition plates, a lamp tube support and an ultraviolet lamp, wherein the box body is of a sealed structure and the bottom of the box body is provided with a reaction surface; the partition plates are arranged in the box body at intervals and are parallel to the reaction surface; light passing holes are formed in the partition plates; the hole centers of the light passing holes in the partition plates are vertically arranged; light absorption coatings are arranged at the peripheries of the light passing holes in the partition plates; the lamp tube support is arranged at the top of the box body and is used for supporting the ultraviolet lamp; and the ultraviolet lamp has a certain distance from thepartition plate at the uppermost layer and is arranged along the diameters of the light passing holes. Inclined UV light is completely prevented through the multiple layers of partition plates, onlythe light which passes through the light passing holes and is perpendicular to the light passing holes is left, and the light absorption coatings on the layers of partition plates can absorb the UV light scattered to the peripheries of the light passing holes, so that the collimated beam apparatus has the advantages of high beam parallelism, high illumination intensity and the like, and is particularly suitable for an ultraviolet light reaction device capable of accurately quantifying the irradiation dose.

Description

technical field [0001] The invention relates to the technical field of ultraviolet (UV) disinfection and UV photochemical reaction, in particular to a quasi-parallel beam instrument capable of accurately quantifying UV dosage. Background technique [0002] Ultraviolet (UV) disinfection technology has the advantages of high efficiency, good broad-spectrum, no disinfection by-products, easy maintenance and operation, and small footprint. It is widely used in the disinfection of sewage, drinking water, reused water, etc. Currently, UV The application of disinfection technology has spread all over the world. With the increasing application of UV disinfection technology, there is an urgent need for systematic evaluation and verification of UV equipment. For example, UV equipment manufacturers need an objective and fair evaluation method to evaluate their product quality, and design units need to have accurate disinfection methods. The effect data is used to ensure the safety and...

Problems solved by technology

[0004] However, at present, there is no clear guidance or specification for the construction of collimated beams at home and abroad, and there are large uncertainties and experience in its construction parameters. At present, there is no professional quasi-parallel beam instrument manufacturer in China. Some existing processing There are many shortcomings in the quasi-parallel beam meter produced by the custom-made manufacturer, which are mainly reflected in the low output light intensity and insufficient parallelism.
