Description
Technical field
The present invention relates to the device or instrument for being convenient for optic test, more particularly to prevent the part of Optical devices from staiing
Or the device of light path obstacle.
Background technology
For increasingly serious Present Situation of Air Pollution, various countries pay much attention to monitoring thermal power plant, Metallurgical Factory, chemical plant and water
The fume emission of the stationary sources such as mud factory, national environmental protection department also all formulates the discharge standard related to having promulgated one after another, causes
Power is in the smoke pollution of the industrial fixed-contamination boiler of control.In recent years, having carried out substantial amounts of spectroscopy detection technique both at home and abroad should
The correlative study work detected used in Pollution Gas, spectroscopy detection technique has high accuracy, fast response time, noncontact
Many advantages, such as formula is measured.Environmental administration is realized to thermal power plant, metallurgy by discharging the monitoring of flue real-time continuous to dusty gas
The supervision of the fume emission of the stationary sources such as factory, chemical plant and cement plant.
The metering system of air flue emission pollutant mainly has extraction-type and in-situ type to measure two kinds, wherein extraction-type detection side
Formula is extracted flue gas out using special heating sampling probe from flue, enters detection after heat tracing transmission and necessary pretreatment
Unit, the pretreatment system usually required that is extremely complex, and detection unit requires that tightness is high, and for such as sulfur dioxide, ammonia
The easily adsorbed gas such as gas, the gas componant being drawn into detection unit can lose, and cause detection error very big.Relative to taking out
Optical transmitting and receiving device is directly arranged on flue by modus ponens, in-situ type metering system, makes measurement light pass through tested flue gas directly to enter
The method of row detection, simple in construction, easy for installation, without complicated pretreatment system, the response time is fast, and measurement result has more
Authenticity.
" one kind is used to carry out flue gas in flue application publication number disclosed in CN103575659A application for a patent for invention
The device of detection " is a kind of device of in situ detection flue gas, and the device is made up of laser beam emitting device and laser receiver,
