Description
Technical field
This utility model relates to thermal power generation gaseous contaminant monitoring technical field, in particular to a kind of the escaping of ammonia
Rate Multipoint Uniform sampling and measuring system.
Background technology
Polluting environment for preventing boiler combustion from producing too much NOx, denitration technology has been widely used in thermal power plant, de-
Causing the escaping of ammonia rate big because of all factors during nitre, the ammonia of escape and sulfur trioxide react generation ammonium sulfate to denitration downstream
Equipment corrosion, and pollute environment, the most accurately, sensitive, fast monitored the escaping of ammonia rate be the premise that denitrating system optimization runs.
The escaping of ammonia rate measuring instruments is substantially employing wavelength modulation spectrum technology at present, according to metering system, mainly has:
1, tradition extraction-type
Utilize jet pump or peristaltic pump equal power device by outside fume extraction to flue, and by multi-stage filter core in flue gas
Dust filter.Flue gas after filtration enters measures air chamber, measures air chamber and uses heater to heat, and heating-up temperature is about
It it is 180 DEG C.Laser emission end and laser receiving terminal are respectively arranged and measure air chamber two ends, are used for launching and receiving measurement signal.
Owing to heat tracing temperature only has about 180 DEG C, far below measuring point temperature (about 300 DEG C), temperature difference can cause sample gas componant
Changing, measurement result can not represent the truth of the escaping of ammonia rate in flue.
2, in situ to the formula of biography
Laser emission end and laser pick-off end are directly mounted at flue both sides, and the laser that Laser emission end is launched is through flue
After being absorbed by the ammonia in flue gas, the laser pick-off end of flue offside receive and measure signal.Due to load variations, walling of flue shake
Dynamic, a blowing out flue deformation often makes transmitting and recruiting unit to be directed at, and receives unit and cannot detect laser signal, cigarette
In gas, dust makes laser intensity decay very serious so that flue cannot be passed through, and certainty of measurement is relatively low.
All there is certain defect, the mistake that particularly flue gas extracts or measures in flue in above-mentioned metering system
Cheng Zhong, in flue, flue gas flow field is uneven, and the extraction flue gas caused or measurement error are relatively big, causes the measurement result can not be the most anti-
Reflect the concentration of the escaping of ammonia rate in flue, i.e. measurement result is the most representative.
Utility model content
Present inventor finds under study for action, and the poor main cause of measurement system accuracy of the prior art exists
In, when using traditional extraction mode, measure air chamber and use heater to heat, heating-up temperature and the temperature far below measuring point
Degree；When using in situ to the formula of biography, owing to load variations, walling of flue vibrations, a blowing out flue deformation often make to launch and connect
Receiving unit cannot be directed at, receive unit and cannot detect laser signal, in flue gas, dust makes laser intensity decay the most serious
So that flue cannot be passed through；And during more existing employing sampling modes measurements, ammonia skewness in some regions, sample
The sample point of gas is the most single, thus causes sampling result to there is error, and accuracy is the highest.
This utility model provides a kind of the escaping of ammonia rate Multipoint Uniform sampling and measuring system, it is intended to improve of the prior art
The flue gas of extraction or the result measuring flue gas can not truly reflect the concentration of the escaping of ammonia rate in flue, i.e. measurement result does not has
Representative problem.
