Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of multicomponent gas collection analysis device provided by the embodiment of the utility model.
Specific embodiment
It is described in detail below in conjunction with feature and principle of the attached drawing to the utility model, illustrated embodiment is only used for explaining
The utility model not limits the protection scope of the utility model with this.
Fig. 1 is a kind of structural schematic diagram of multicomponent gas collection analysis device provided by the embodiment of the utility model.Referring to
Fig. 1, the multicomponent gas collection analysis device, including light emitters 11, light receiver 12, detection circuit 13, sample detecting
Chamber 14, adsorption pump 15, the first cleaning structure 16, the second cleaning structure 17, controller (not shown in figure 1) and comparator 18.Institute
It states light emitters 11 and the light receiver 12 is set in the sample detecting chamber 14, the adsorption pump 15 is adopted with described
Sample test chamber 14 is connected；The detection circuit 13 is electrically connected with the light receiver 12.
The light emitters 11 include beam projecting face 110, first cleaning structure 16 and the beam projecting face
110 are in contact, and can be reciprocating in the plane in 110 institute of beam projecting face；The light receiver 12 includes
Light receiving surface 120, second cleaning structure 17 are in contact with the light receiving surface 120, and can connect in the light
120 institute of receipts face is reciprocating in the plane.
First cleaning structure 16 and second cleaning structure 17 are connected with the controller.
The comparator 18 is connected with the light receiver 12 and the controller.
Wherein, light emitters 11 are for emitting light.Light receiver 12 is used for the light that light emitters 11 are emitted.
Since different component (i.e. different material) is different to the absorbability of the light of different wave length in gas, light is through gas to be detected
After will form absorption spectrum.Detection circuit 13 is by absorption spectrum may be implemented the content to component and each component in gas
The purpose detected.
Controller moves back and forth on beam projecting face 110 for controlling the first cleaning structure 16, to realize to light
Line exit facet 110 carries out clean purpose.Meanwhile controller is also used to control the second cleaning structure 17 in light receiving surface 120
On move back and forth, with realize clean purpose is carried out to light receiving surface 120.
It enables beam projecting face 110 and light receiving surface 120 be under ideal clean state, does not absorb gas to be detected
When, the 12 collected absorption spectrum of institute of light receiver of multicomponent gas collection analysis device is the first spectrum；Beam projecting face
110 and light receiving surface 120 it is cleaned after, when not absorbing gas to be detected, the light receiver of multicomponent gas collection analysis device
The 12 collected absorption spectrum of institute of device is the second spectrum.Comparator 18 is based on for comparing the first spectrum and the second spectrum
Comparing result obtains the cleannes of current light exit facet 110 and light receiving surface 120.Controller is connect with comparator 18, is used
In the cleannes based on current light exit facet 110 and light receiving surface 120, the first cleaning structure of control 16 and the second cleaning knot
Structure 17 continues to move back and forth or stop.It can make to be attached on beam projecting face 110 and light receiving surface 120 in this way
Dust particles sufficiently remove.
Multicomponent gas collection analysis device provided by the embodiment of the utility model can solve existing multicomponent gas and adopt
Set analysis device after prolonged use, can be attached on the beam projecting face of light emitters and the light receiving surface of light receiver
Some dust particles, this part dust particles can make asking for the content detection accuracy decline of component and each component in gas
Topic realizes the effect for improving the content detection precision of component and each component in gas.
Optionally, first cleaning structure 16 and second cleaning structure 17 include cleaning brush.
