Description
Technical field
The utility model is related to gas detection technology field, particularly a kind of reliable operation is durable and with wider concentration
More backhaul long light-path sample gas ponds of polluted gas detection range.
Background technology
Sample gas pond is a kind of to be developed, wide at present based on various gas molecules all characteristics with respective specific absorption spectrum
The general gaseous contamination degree detection device being applied in environmentally friendly flue gas monitoring system.At present in environmentally friendly gas precision context of detection, than
More common is the more backhaul long light path sample gas ponds of light path Zigzag type, its main feature is that optical length, accuracy of detection are high, can be used to detect low dense
The polluted gas of degree meets current environmental protection standard and improves requirement increasingly very much.The light in the more backhaul long light path sample gas ponds of light path Zigzag type
Road is relatively complicated, and typical structure is one of to be as shown in Figure 1, include three pieces of identical reflective mirrors of radius of curvature
The larger big reflective mirror B of bore, remaining two pieces are basic size is identical, bore is smaller and big reflective mirror B is in remote centre pair
Claim the small reflective mirror A and A ' against arrangement.During work, incident light passes through the collimating mirror being located near big reflective mirror B one side edges and throws
To small reflective mirror A, then reflect on fold back to big reflective mirror B, then reflect on fold back to small reflective mirror A ', finally reflection fold back,
Directive is located on the focus lamp of big another near side edges of reflective mirror B, and the emergent light spot alignment of line focus generation is precipitated in optical fiber
In receiving point, then optical fiber is transferred to spectrometer analysis.So big reflective mirror B, the relative positioning accuracy of small reflective mirror A and A '
Most important, any mirror position or the micro- of angle can cause light to deviate normal orbit partially, make outgoing dot projection point
Deviation occurs, so as to influence the reliability of testing result.In practice, it has been found that it is possible that influence each reflective mirror setting accuracy
Factor is more, including sample gas pond mechanical component expanding with heat and contract with cold during the work time, the vibrations in working environment or and temperature
Humidity variation and sample gas pond are long placed in the variation without internal stress under state.Since the existing more backhauls of light path Zigzag type are long
Light path sample gas pond, so optical registration deviation once has occurred, can only scrap update, both affect ring as a result, without deviation-correcting function
The normal work of flue gas monitoring system is protected, and shortens the normal working life in sample gas pond, also leads and improves routine use cost,
A big puzzlement of sample gas pond manufacturer and corresponding functional department is had become at present.So consider from economy and point of view of practicability,
Still owe ideal.
