Abstract
The utility model relates to a novel deuterium lamp light path device, which consists of a deuterium lamp module, a lens and a detection module. The device is characterized in that the deuterium lamp module is formed by arranging a deuterium lamp in an outer casing of the deuterium lamp, a light outlet window of the deuterium lamp is aligned with the part just in front of a light ray hole of the outer casing of the deuterium lamp, the detection module is formed by tightly attaching a filtering sheet and a photoelectric cell, the lens is positioned just in front of the light ray hole of the deuterium lamp module, the detection module, the light ray hole of the deuterium lamp module and the lens are positioned on a straight line, and a colorimetric pool is positioned between the lens and the detection module. The device has the advantage that the dispersed lights emitted by the deuterium lamp are focused into parallel lights by the lens, and the parallel lights penetrate through the colorimetric pool and the filtering sheet to enter the photoelectric cell, so the current of the photoelectric cell can be detected, and the concentration of a solution to be monitored can be calculated. The device is suitable for being installed on the on-line monitoring equipment, such as total nitrogen, nitrate nitrogen and COD (chemical oxygen demand), so the concentration of a solution to be monitored is monitored in an on-line way.
Description
Technical field:
The utility model belongs to the ultraviolet source monitoring device, and is particularly a kind of with the novel deuterium lamp light path device of deuterium lamp as ultraviolet source.
Background technology:
The monitoring of a lot of materials is based on ultraviolet spectrophotometry analysis, therefore need to use ultraviolet source, wherein, deuterium lamp has stability and the continuity of height, so the application of deuterium lamp light path detecting device in the on-line monitoring analytical instrument such as total nitrogen, nitrate nitrogen, COD is particularly extensive.Prior art is to utilize the photoelectric sensor receiving optical signals, converts light signal to electric signal, shows by indicating circuit, and when weak point was the photoelectric sensor receiving optical signals, glitch appearred in the interference that is subject to easily ambient light.
Summary of the invention:
The purpose of this utility model is to propose a kind of novel deuterium lamp light path device, can be installed on the on-line monitoring equipment such as total nitrogen, nitrate nitrogen, COD and use, and obtains accurately optical path signal.
The technical scheme that the utility model proposes is, a kind of novel deuterium lamp light path device, formed by deuterium lamp module, lens and detection module, the deuterium lamp module is in the deuterium lamp enclosure deuterium lamp to be installed to form, the light-emitting window of deuterium lamp is aimed at the dead ahead in the light hole of deuterium lamp shell, detection module is close to photoelectric cell by optical filter and is formed, lens are positioned at the dead ahead in the light hole of deuterium lamp module, the light hole of detection module and deuterium lamp module, lens point-blank, colorimetric pool is between lens and detection module.
Deuterium lamp in the aforesaid deuterium lamp module is side window type, and the cross section of deuterium lamp shell is circular, and inside is hollow cylinder.
Aforesaid lens are plano-convex lens, and the cross section is circular.
The optical filter of aforesaid detection module and photronic section are circular.
