Description
Technical field
The utility model relates to a kind of parallel beam instrument, especially a kind ofly is used to measure the assay parallel beam instrument of dosage of ultraviolet biology.
Background technology
The disinfection by ultraviolet light technology is a kind of cleaning of rising in recent years, the disinfection technology of safety, is widely used in water treatment and the air sterillization.The radiation dose of determining ultraviolet lamp tube is a core link of using the disinfection by ultraviolet light technology.All the time, it is to calculate with theoretical method to get that uv dosage is established a capital really, represents disinfection by ultraviolet light dosage with the ultraviolet radiation intensity of mensuration and the product of radiated time under the breadboard ideal conditions.Yet years of researches and practical engineering application experience show that the theoretical calculation method of the uv dosage that provides among " municipal effluent sterilization design manual " (1986 US EPA Design Manual) of Environmental Protection Agency's publication in 1986 is insecure.
Many manufacturers serve as to be less than its half of theoretical according to effective uv dosage that the ultraviolet ray disinfecting system of producing can reach with these computing method.When under breadboard ideal conditions, measuring radiation intensity, not can take into account the several factors that influences radiation intensity that occurs in the practical application, as the placement location of the turbidity of water, the variation of flow, ultraviolet penetrance, fluorescent tube and the deactivation dynamics of microorganism, but these factors all can impact ultraviolet radiation dose.Thereby the theoretical calculation method that utilizes " municipal effluent sterilization design manual " medium ultraviolet dosage is applied to actual ultraviolet ray disinfecting system, through regular meeting make processed water sterilization sterilization not exclusively, not thorough, can't satisfy water quality requirement, this point is badly in need of improving.
Summary of the invention
The utility model provides a kind of assay parallel beam instrument of dosage of ultraviolet biology that is used to measure.
Biology assay dosimetry more science, determine uv dosage exactly.The biology dosage of assaying carries out under water quality that is virtually reality like reality and service condition, and the uv dosage of experiment gained has been taken all factors into consideration the various influence factors in the actual motion, therefore more accurately, reliable, satisfies actual needs.
Parallel beam instrument in the utility model comprises support bar, radial chamber, directional light passage, planchet, magnetic stirring apparatus, objective table, base and ultraviolet lamp tube.Radial chamber all is columniform cavity with parallel optical channel, and is orthogonal, is "T"-shaped connection, and material is stainless steel, the directional light passage be positioned at radial chamber under.Support bar is arranged in the bottom of radial chamber both sides, is used to support radial chamber and parallel optical channel.Radial chamber is provided with switching knob, the radiation intensity that is used for the switch fluorescent tube and regulates ultraviolet lamp tube.
The radial chamber two ends are equipped with opening, have two tube stands to be used for fixing in the cavity and support ultraviolet lamp tube.Each opening is equipped with the screw socket end cap, and the side of screw socket end cap in cavity links to each other with the tube face of ultraviolet lamp tube, and the end cap handle is housed on the opposite side, is used for the screw socket end cap is screwed out or the precession cavity.
Ultraviolet lamp tube is contained in the center of radial chamber, is fixed by the tube stand of radial chamber, can regulate ultraviolet radiation intensity as requested.Ultraviolet ray that ultraviolet lamp tube sends is through radial chamber, from the exit parallel radiation of directional light passage to planchet.Planchet be positioned over the directional light passage under, magnetic stirring apparatus is arranged below, in ultraviolet radiation, stir, keep sample evenly.
Objective table be arranged in the directional light passage under, be used to carry magnetic stirring apparatus and planchet.Objective table is provided with objective table height control handle, can the experimental different objective table height that require to regulate.
After opening the switching knob energized, the ultraviolet ray that ultraviolet lamp tube sends is radiated on the planchet through the directional light passage, can regulate the radiation intensity of ultraviolet lamp tube according to different requirements.
The radiation dose of ultraviolet lamp tube is important measurement index in the ultraviolet lamp tube performance.Parallel beam instrument in the utility model can be realized mensuration that the fluorescent tube biology is assaied dosage, makes this important parameter of uviol lamp radiation dose science, more accurate more surely really.
