Description
Technical field
The utility model relates to a kind of flue dust detection laser emitter, this technical field is the application of photoelectron technology on the continuous monitoring dust concentration.This utility model constitutes by a plurality of modules such as flue, light path, transmitter unit housing, optical filter, Laser emission seat, detector, laser instrument, set screw, control circuit, is convenient to replace maintenance again.It is easy to use, reliability is high, guarantees the emission of test light, has reached reliable, stable, accuracy is high and the purpose of easy care.
Background technology
The test dust concentration all adopts traditional isokinetic sampling's method both at home and abroad at present, and whole sampling process comprises: preparation, mensuration, sample analysis, calculating, brief summary five parts.Monitoring a dust concentration needs 3～4 technician just can finish its equipment complexity, waste of manpower, and the concentration value of measuring flue dust that can't be continuous, online.The development of the continuous flue gas monitoring equipment of China is in the junior stage, and the device development of laser method continuous monitoring dust concentration still is in the exploratory stage.
Summary of the invention
The purpose of this utility model, be to inquire into a kind of laser beam emitting device of novel dust concentration continuous detecting, the use of this device can guarantee the stable output and the angular adjustment of LASER Light Source, and launch test light and reference light simultaneously, thereby finish the follow-on test of dust concentration and the calibration of system.
The purpose of this utility model is achieved through the following technical solutions: by organic formation of a plurality of parts such as transmitter unit housing, light splitting piece, Laser emission seat, detector, laser instrument, set screw, control circuit, the test light that laser instrument is sent, formed two-way light through behind the light splitting piece, one the tunnel as the test usefulness test light by the tested gas that grinds, another road as a comparison with the calibration usefulness datum ray, accept by detector.Can finish testing the adjusting of light emission angle by set screw.
The utility model has following advantage after adopting technique scheme: by optical splitter the light beam that single light source sends is divided into two-way, makes the electric drift performance of two-way light identical, therefore effectively offset the influence of electric drift to measuring accuracy in test.In addition, can finish easily testing the adjusting of light emission angle, simplify the installation process of proving installation by set screw.
Description of drawings
Fig. 1 is the synoptic diagram according to the flue dust detection laser emitter that the utility model proposes.
Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
This device is made up of following 9 parts: flue 1, light path 2, transmitter unit housing 3, optical filter 4, Laser emission seat 5, detector 6, laser instrument 7, set screw 8, control circuit 9.Laser beam is sent by laser instrument 7 and forms light path 2, the light path of sending 2 is carried out beam split through light splitting piece 4, one beam optical path, 2 directions are constant but can decay 50%, passage through Laser emission seat 5 and transmitter unit housing 3, enter the flue 1 of test, the reflection of another beam optical path receives through detector 6, turns back to control circuit 9 and judges and calculate that the sender of light path 2 is to being regulated by set screw 8 with angle.
