Abstract
The invention discloses an optical device for on-line measurement of oil in water by utilizing fluorescence spectrum, and the optical device is realized by arranging a sample funnel, respectively arranging an input light path consisting of an ultraviolet light source and lenses and a receiving light path consisting of a visible light monochromator and a photoelectric detector on both sides above the sample funnel. Because the device adopts the structure, especially the sample funnel, the ultraviolet light source and the visible light monochromator replace a sample pool, an infrared light source and an infrared monochromator in the prior art, the optical device can directly lead measured water to the sample funnel, not only can directly monitor content of oil in water in the on-line mode, and overcomes the disadvantages of high requirement of the existing device to an electronics system and high cost, and has the advantages of novel and unique product idea, compact and reasonable structural layout, stable and reliable working performance, convenient, economic and practical use, suitability of popularization and application, and the like.
Description
Technical field:
The present invention relates to a kind of optical system, particularly relate to a kind of optical devices that utilize oil in the fluorescence spectrum on-line measurement water.
Background technology:
Oil is that one of pollutant qualified discharge overall control project is carried out in the national environmental protection decision-making, as water source monitoring, industrial sewage, tanker berth, refinery, chemical plant, main equipment chilled water, power station or the like, all will monitor the oil in the water.At present the measurement major part of oil in the water being taked infrared spectrophotometer (as shown in Figure 2) promptly is to take in the both sides of sample cell input path and receiving light path to be set respectively, input path is made up of infrared light supply and lens, and receiving light path is made up of lens, infrared monochromator and photodetector, and incident light axis and receive optical axis on same straight line.Described device is because infrared light is more weak through signal behind the sample cell, when therefore adopting the infrared light photometric measurement, require very highly for the electronic system of instrument, this has not only increased the cost of instrument, and requires the sample just energy measurement that must remain static.So, can only extract sample and monitor, can't on-line measurement, make to use to be restricted.
Summary of the invention:
The present invention is for a kind of optical devices that utilize in the fluorescence spectrum on-line measurement water oil are provided, mainly be solve that existing optical devices exist electronic system is required height, problem that can't on-line measurement.
The solution of the present invention is as described below: this invention comprises lens and photodetector, it is by sample funnel is set, and both sides are established the input path be made up of ultraviolet source and lens respectively and the receiving light path realization is made up of lens, visible light monochromator and photodetector above sample funnel.The incident light axis of described input path and receiving light path, receive optical axis, and be respectively 0-30 ° with the horizontal plane angle of sample funnel all with sample funnel symcenter symmetry.
Beneficial effect of the present invention: because this device has been taked said structure, particularly get and replaced existing sample cell, infrared light supply, infrared monochromator with sample funnel, ultraviolet source, visible light monochromator, tested water directly can be introduced sample funnel, can not only monitor content oily in the water by direct-on-line, and overcome existing apparatus to electronic system requirement height, disadvantage that cost is high, have simultaneously the novel uniqueness of product conception, topology layout compact and reasonable, stable and reliable working performance, easy to use economical and practical, be fit to widely popularize advantage such as application.
Description of drawings:
Fig. 1 is a kind of structure of optical means synoptic diagram that utilizes oil in the fluorescence spectrum on-line measurement water;
Fig. 2 is an infrared spectrophotometer structure of optical means synoptic diagram.
Embodiment:
By a kind of optical devices that utilize oil in the fluorescence spectral measuring water shown in Figure 1, its bottom is a sample funnel 1, and the both sides, top of sample funnel 1 are provided with input path of being made up of ultraviolet source 2 and lens 3 and the receiving light path of being made up of lens 4, visible light monochromator 5 and photodetector 6 respectively.Wherein ultraviolet source 2 is in the place ahead of lens 3, and lens 4 are in visible light monochromator 5 the place aheads, and photodetector 6 is at the rear of visible light monochromator 5.The incident light axis of input path and receiving light path, receive optical axis, and be respectively 0-30 ° with the horizontal plane angle of sample funnel 1 all with sample funnel 1 symcenter left-right symmetric.Wherein sample funnel 1 adopts plastics, glass or stainless steel to make, ultraviolet source 2 adopts common deuterium lamp or xenon lamp, lens 3,4 adopt quartz or simple glass to make, visible light monochromator 5 is common grating beam splitting monochromator or optical filter monochromator, and photodetector 6 adopts photodiode, photomultiplier all can.Other is known so omit for those of ordinary skills.
During work, water enters sample funnel 1 from sample funnel 1 below with certain speed, periphery at sample funnel 1 overflows, on sample funnel 1, form a smooth surface level, ultraviolet light scioptics 3 parallel radiation that ultraviolet source 2 sends are on this surface level, at this moment the oil in the water is subjected to sending fluorescence after UV-irradiation excites, fluorescence scioptics 4 are sent to visible light monochromator 5,5 of visible light monochromators allow the fluorescence of tested wavelength to pass through, and last tested fluorescence is received by photodetector 6.
