According to the invention, adjusting of an optical path is convenient and reliable, and reception of reference signals is stable; the monitor has a small volume and a simple structure and is convenient to operate.
Description
Technical field
The present invention relates to the flue dust monitor, especially the light path regulating device of flue dust monitor and reference signal receiving trap.
Background technology
Flue dust on-line monitoring appearance is a kind of instrument that stationary pollution source is carried out online auto monitoring.Adopt back scattering method principle to accomplish mensuration, solved the automatic monitoring problem of being badly in need of in China's environmental monitoring of pollution source flue dust on-line continuous cigarette (powder) dust concentration of tested flue.Can be used for the on-line continuous monitoring of all pollution source flue dust, have compact conformation, characteristics simple, anti-adverse environment are installed, can provide fast, quantitative soot emissions data reliably and accurately, cost is low, maintenance is little.
Adopt infrared back scattering mode, an infrared beam is injected flue, when infrared rayed is to particle, light scattering phenomenon takes place, scattered intensity changes along with the variation of particle concentration.Back scattered light can converge and received by sensor by scioptics, and sensor converts the light signal that receives to electric signal, through amplifier circuit and computing circuit, calculates particle concentration.
Each different pollution source is on-the-spot; The chimney diameter of measuring is also inequality; Cause each different chimney that different measurement sensitizing ranges all can be arranged; (so-called sensitizing range promptly refers on the soot dust granule thing of light source irradiation at this intra-zone, and the variable quantity after the light intensity that the scattering that receives is returned can reach measurement requirement and its scattering is returned when changing contaminant particle concentration light intensity and changes into electric signal is in maximum rating); Principle of work according to the flue dust monitor; Chimney for different measure field different-diameter sizes; Thereby the angle of pitch that needs the adjusting light source changes the angle of light path can shine in the measurement sensitizing range of chimney light source accurately, makes the measurement effect of flue dust monitor reach optimum condition.
Summary of the invention
The object of the invention just provides a kind of flue dust monitor that can conveniently regulate light path and conveniently can carry out providing for main optical path reference signal.
The technical scheme that the present invention adopts is: a kind of flue dust monitor with light path adjusting and reference signal receiving trap; It comprises outer cover, is positioned at the light source of outer cover, is installed in focus lamp and main optical path sensor on the outer cover; The light that light source sends is met soot dust granule and is returned after focus lamp focuses on the main optical path sensor, it is characterized in that it also comprises a light path regulating device, and described light path regulating device comprises mount pad and is connected in first bolt and second bolt on the mount pad; Described light source and main optical path sensor be separately fixed at mount pad about; Described mount pad comprises parallel upper plate and lower shoe, and light source and main optical path sensor are individually fixed on upper plate and the lower shoe, and upper plate and lower shoe one end are connected as a single entity through the toughness end; The other end of lower shoe is respectively equipped with screw and through hole; The through hole correspondence position of upper plate is provided with screw, and first bolt cooperates with the screw of lower shoe, and the end of first bolt is squeezed in the lower surface of upper plate; Second bolt is positioned at the through hole of lower shoe, and second bolt connects with the screw of upper plate after passing through hole.
Adopt technique scheme, when regulating light path,, can realize the angle between the lower shoe of upper plate, thereby realize the adjusting of light path as long as rotate first bolt and second bolt.
As further improvement of the present invention; It is characterized in that also comprising that is participated in a signal receiving device; Described reference signal receiving trap comprises semi reflective lens, reference path sensor and reflective mirror; Described reference path sensor is fixed on the below of light source, and described semi reflective lens are inclined in the place ahead of light source, and reflective mirror is given the reference path sensor to the light transmission of semi reflective reflection from lens.The light that sends when light source is during through reflective lens, and part light will reflect and be transferred to the reference path sensor from reflective mirror, as signal contrast light.
In sum, beneficial effect of the present invention is: make the light source of flue dust monitor convenient fixing, quick detachable, easy to adjust, reliable, the reference signal of light path receive stable.Volume is little, and is simple in structure, easy to operate.
