Description
Technical field
The utility model belongs to flue gas inspection field, specifically, continuously monitoring on-line the utility model relates to flue gas and being
System.
Background technique
The continuous on-line monitoring system of flue gas is the equipment continuously monitored on-line to stationary source sewage draining exit, passes through 24
Hour continual monitoring sewage draining exit polluter, such as SO2With the concentration of NOx, realize Environmental Protection Agency to stationary source enterprise
Blowdown condition monitoring.The continuous on-line monitoring system of flue gas is generally divided into flue gas pretreatment part, flue gas concentration analysis part sum number
It is grouped as according to storage upload unit.
Flue gas pretreatment part extracts the flue gas of sewage draining exit out sewage draining exit, and it is dense to be sent into flue gas after pre-processing to flue gas
Degree analyzer is analyzed.Since flue gas has high temperature, high humidity, characteristic dusty, whole heat tracing is needed in sampling process,
The temperature of heat tracing needs to install the dust filter unit of small-bore in sampler front generally at 140 degree, so that into heat tracing
The flue gas of pipe is free of dust particles.When flue gas enters that analyzer is small behind the house by heat tracing pipe, one 4 degree of condensation can be passed through
Flue-gas temperature is reduced to 4 degree rapidly by device, so that most of moisture condensation in flue gas is liquid water and is arranged by peristaltic pump
Cabin out.The process of flue gas condensing must be very fast, otherwise the SO in flue gas2It is to be measured to cause that gas can be dissolved in condensed water
The loss of concentration of component.Pretreated flue gas squeezes into point that flue gas concentration analyzer carries out pollutant concentration by sampling pump
Analysis.
Flue gas concentration analyzer currently on the market mainly has ultraviolet spectroscopy and two kinds of infra-red sepectrometry.Two methods
Principle is all: according to the Beer-Lambert law of gas molecules sorb, light beam passes through the sample gas in analysis cell,
Since gas is to the absorption of light, light energy will decay, and is tested absorption of the gas in af at wavelength lambda to light intensity, can be used to
Lower formula accurate description:
In formula:
I0(λ) --- incident light is in af at wavelength lambda relative intensity;
I (λ) --- emergent light is in af at wavelength lambda relative intensity;
L --- light path;
Ci--- i-th kind of gas concentration;
σi(λ) --- the absorption coefficient of i-th kind of gas;
ε (λ) --- extinction coefficient caused by the factors such as KPT Scatter.
The difference of ultraviolet spectroscopy and infra-red sepectrometry is for monitoring SO2With the spectral wavelength ranges of NOx, ultraviolet method
Ultraviolet band of the wave-length coverage in 200-400nm, middle infrared band of the wave-length coverage that infrared method uses in 3-6um.
For ultraviolet method and infrared method flue gas concentration analyzer, scene is other using the greatest problem being likely encountered
The absorption bands and SO of gas molecule2It is identical with the absorption bands of NOx, cause cross jamming.Fortunately, most flue gases
The scene that continuous on-line monitoring system uses there's almost no this kind of interference gas, so the continuous on-line monitoring system of flue gas is big
Part occasion can normal use.But for particular applications such as biomass power generation, waste incinerations, due to the combustion used
Material is some wastes, and the structure of matter is very complicated, and due to fuel problem, it is difficult to which full combustion exists and do not fill largely
The intermediate product of divided combustion, such as HC substance.And HC substance spectrally exists largely in absorption line, from ultraviolet to infrared
All exist.In ultraviolet fluctuation, HC substance can absorb the wavelength of 300nm once, and the flue gas analyzer of ultraviolet spectroscopy is caused to exist
There are great errors in the measurement of NO.And in infrared band, the absorption spectrum of HC substance just with SO2Measure spectrum weight
It closes, it can serious influence SO2Measurement.Show currently, generating a large amount of HC interfering substances to this biomass power generation, waste incineration
, ultraviolet spectroscopy flue gas monitoring system and infrared method flue gas monitoring system all can not normal uses.
Therefore, the existing continuous on-line monitoring system of flue gas is further improved at present.
