Measurement flue gas, is to mix heat pipe by one, flue gas is transferred to analyser and is analyzed, but in flue, dust is many, deposition
Dirt leads to the data jump of emission measurement, and measurement is inaccurate.
Content of the invention
The purpose of this utility model is to provide a kind of fume emission monitoring system, to improve the standard of the detection data of flue gas
Really property.
For achieving the above object, this utility model employs the following technical solutions:
Fume emission monitoring system, for monitoring the fume emission situation in flue, including the sampling probe being sequentially connected,
Electric heating tube, sampling pipeline, dehumidifier, analysis cabinet and controller, described sampling probe puts in flue, and sampling probe is pacified
Equipped with ceramic filter, electric heating tube heats to sampling probe, and the gas in flue is transported to dehumidifying by pipeline of sampling
It is delivered to analysis cabinet after device dehumidifying, be provided with infrared detector in described analysis cabinet, analytical data is transmitted by described analysis cabinet
To controller.
Wherein, described filter is silicon carbide ceramic filter, and its filtering accuracy is 5～10 μm.
Preferably, also include intermediate filter, it is between dehumidifier and analysis cabinet.Filtered by two-layer, by dust

Specific embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to this utility model.
As shown in figure 1, the utility model discloses a kind of fume emission monitoring system, arranging for monitoring the flue gas in flue
To one's heart's content condition.Sampling probe 1 that this system includes being sequentially connected, back-blowing device 2, electric heating tube 3, sampling pipeline 4, dehumidifier 5, in
Level filter 6, analysis cabinet 7, alarm device 8 and controller 9.
Sampling probe 1 puts in flue, and sampling probe 1 is provided with silicon carbide ceramic filter 10, and its filtering accuracy is 5
～10 μm, the dust overwhelming majority in flue is blocked in outside ceramic filter 10.Back-blowing device 2 is also connected with sampling probe 1.Instead
Blowing apparatus 2 can prevent dust from piling up around ceramic filter 10, and the impact sample flow of air that results in blockage is it is necessary to timing is carried out instead
Blow.Blowback is controlled by controller 9 according to concrete operating mode cycle time.
Electric heating tube 3 heats to sampling probe 1, and the gas in flue is transported to dehumidifier 5 by pipeline 4 of sampling and enters
Row dehumidifying, sampling pipeline 4 is the corrosion-resistant flexible pipe of politef.Enter intermediate filter 6 after the dehumidifying of sample gas and carry out secondary filter
It is delivered to analysis cabinet 7 afterwards again, in analysis cabinet 7, be provided with infrared detector (not shown), using non-dispersion infrared e measurement technology
Calculate gas concentration: inside infrared detector, two air chambers are divided into by metal partion (metp), light source sends the parallel infrared ray of twice,
It is optical path together, be reference light paths together.Twice light, after sample cell and participation pond, respectively enters inside detector
Two air chambers, sample gas absorbs infrared ray and simultaneously switchs to heat energy, has temperature difference or pressure differential because two Room heat energy are different, this
Pressure differential can make metal partion (metp) be deformed and change the electric capacity of capacitor, and then changes voltage, and voltage signal is by front storing
Big device amplifies, rectification, then signal is reached controller 9, and controller 9 calculates corresponding gas concentration.If detecting the gas obtaining
Bulk concentration is exceeded, then controller 9 startup alarm device 8 sends alarm signal.
To sum up, this utility model by the gas in flue according to the pressure being capable of enough acceptance according to analytical tool, temperature, aqueous
Amount and clean level complete its monitoring process, and certainty of measurement is high, good stability.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
It is confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should cover within protection domain of the present utility model.
