Abstract
The invention relates to a pre-treatment and analysis device and method for online monitoring on H2SO4 acid mist in wet flue gas. The monitoring method mainly comprises the following steps of: pumping coal-fired flue gas from a flue by virtue of a sampling gun, and maintaining temperature of the sampled flue-gas to be 150-250 DEG C by utilizing a heat tracing pipeline; then introducing flue gas into a specific H2SO4 acid mist transforming device filled with phosphorus pentoxide as a transforming agent, transforming H2SO4 acid mist into SO3 easy for online measurement by utilizing dehydration property of phosphorus pentoxide at the temperature of 200-300 DEG C, and adsorbing and drying moisture in the flue gas; carrying out continuous monitoring on SO3 in the dry flue gas by virtue of an instrument which can continuously monitor in real time; and then respectively sequentially passing the exhaust gas through a gas flowmeter and a sampling pump and finally discharging into the atmosphere. Compared with the prior art, the pre-treatment and analysis device and method for online monitoring on H2SO4 acid mist in wet flue gas can eliminate interference of moisture, acid mist and SO2 in the flue gas, and SO3 gas in exhaust gas of the flue gas can be accurately monitored.
Description
Technical field
The invention belongs to field of environment protection, relate to H in a kind of wet flue gas
2SO
4The pre-treatment of acid mist on-line monitoring and analytical approach utilize this Apparatus and method for can get rid of the interference of moisture and other components in the flue gas, accurately the SO3 gas in the flue gas are detected.
Background technology
Oxysulfide major part in the coal-fired flue-gas is SO
2, it is SO that sub-fraction is wherein also arranged
3Along with SCR (Selective Catalytic Reduction) technology begins to be applied in China, the active component in the SCR catalyzer can catalysis be accelerated SO
2Oxidation reaction, and promote SO
3Generation, cause SO in the coal-fired flue-gas thus
3And sulfuric acid mist (SO
3/ H
2SO
4) concentration significantly increases.
SO
3Be a kind of material of very easily moisture absorption, studies show that when temperature surpasses 200 ℃, and the moisture in the flue gas is when surpassing 8% left and right sides, 99% SO
3All will be converted into sulfuric acid mist; And when flue-gas temperature was lower than the dewpoint temperature of sulfuric acid vapor, sulfuric acid mist can condensation form sulfuric acid droplets, and wherein the sulfuric acid droplets of 0.5-3.0 μ m can form the sulfuric acid gasoloid.As PM
2.5Presoma sulfuric acid gasoloid again can be to PM
2.5Discharging cause material impact.Simultaneously, sulfuric acid mist also may stick to the upstream device of boiler or SCR system, as the surface of equipment such as air preheater, electrostatic precipitator, can cause serious corrosion to these equipment during long-time running.Therefore, SO in monitoring and the analysis flue gas
3/ H
2SO
4Concentration, for regulation and control boiler operatiopn condition, it is most important to reduce the sulfuric acid aerosol discharge.Yet, still do not have the SO that obtains extensive approval at present
3/ H
2SO
4Monitoring method.The flue gas analyzer that is widely used in fume component analysis is not analyzed SO yet
3This function of content, this mainly is because SO
3Chemical property is active, H
2SO
4The gasoloid adsorbability is strong, and they are very easily adsorbed by various material walls, and surveying instrument and sample devices are caused corrosion, makes instrumental calibration and quantitative measurement have great difficulty.Secondly, the SO that has high concentration in the flue gas
2, measure the SO in the flue gas
3The method of content generally is to be translated into SO
4 2-Behind the sample solution, by analyzing SO
4 2-SO is measured in the content brief introduction
3Content.Yet this detection method is easy to be subjected to SO
2Interference because SO
2In absorption liquid, can generate SO
3 2-, and SO
3 2-Can be oxidized to SO
4 2-, this will cause flue gas SO
3Concentration monitoring causes error.The 3rd, the SO in the flue gas
3Concentration is very low, and less error at measurment can be brought bigger relative error.Chinese patent application 2O0610095389.8 has proposed SO in a kind of flue gas
3Content detecting method and device wherein utilize the spiral collection tube to gather the SO in the flue gas
3, and after handling, obtain SO
4 2-Sample solution is by SO in the analytic sample
4 2-The cubage flue gas in SO
3Concentration.This method is for the SO that gathers the droplet shape
3Relatively effectively, but for the SO of gaseous state
3Just can not effectively collect, and adopt this device also the water vapor in the flue gas may to be collected in the lump, so just may be with the SO in the flue gas
2Also absorb, and resultant interference is to SO
3The detection of content.Chinese patent application 200910211691.9 proposed to utilize a kind of for detection of, measure and control flue gas in the method and apparatus of sulfuric anhydride and other condensable material.This method is utilized the electric signal difference that the dew point of different material is different and produce when condensing in device, the condensables in the flue gas is monitored.But this method is difficult to H
2SO
4Acid mist with absorbed SO
2The water vapor of gas is distinguished.Therefore, currently demand seeking SO in the new flue gas urgently
3The monitoring method of content.In addition, existing aqueous isopropanol absorbs in conjunction with SO in the thoron colour developing titration measuring flue gas
3Also there is SO
2Disturb excessively, be difficult to realize the problem of continuous real-time monitoring.
In addition, for the flue gas of wet desulphurization or dedusting, wherein SO
3Substantially all be converted into acid mist, and these acid mists are difficult to effectively be removed, can form gasoloid or PM along with fume emission enter atmosphere
2.5Material.But, because moisture is higher in this class wet flue gas, sulfuric acid mist directly to be measured comparatively difficult, not only error is bigger for above-mentioned several measuring methods, samples simultaneously and analyzes the requirement that is difficult to satisfy the flue gas continuous real-time monitoring.Therefore, if can utilize suitable method with the moisture removal in the flue gas, simultaneously sulfuric acid mist is converted into SO
3, then can utilize infrared or the laser measuring technique method to the SO in the flue gas
3Carry out measuring in real time fast.
