Technical field
The utility model belongs to pollutant monitoring field, particularly a kind of to be used for power plant sulfur dioxide concentration Site Detection
Device.
Background technology
With the proposition of China's minimum discharge requirement, discharge standard of the Environmental Protection Agency to sulfur dioxide concentration in power plant stack gas
35mg/m3 is had been lowered to, this China power plant is generally handled flue gas using Wet Flue Gas Desulfurization Technology.Wet method takes off
After sulphur, the smoke moisture of desulfurizing tower outlet is very big, and water capacity volume fraction is up to 13% or so, droplet content about 30mg/m3,
And temperature is general between 45~65 DEG C.Sulfur dioxide is soluble in water, the dioxy of the volume of 1 volume water dissolvable 40 under normal condition
Change sulphur, thus desulfurization fume special state the Accurate Determining at power plant sulfur dioxide concentration scene is caused it is very big tired
Difficulty, especially under winter low temperature environment.
The method of current China stationary source content of sulfur dioxide detection has：
1. directly extraction flue gas (band heating) → condensation is dry or desiccant dryness → dedusting → non-dispersion infrared instrument is examined
Survey method, this method is the current most popular method applied to Site Detection, but because flue gas after desulfurization sulfur dioxide is dense
Spend very low, humidity very big, condensation drying can make substantial amounts of sulfur dioxide be dissolved in condensed water, to the accuracy shadow of testing result
Sound is very big, and desiccant dryness is limited in one's ability, and the drying effect for being unable to reach needs is used alone, though therefore this method using,
But there are the problems such as systematic error is big for Site Detection；
2. flue gas (band heating) → damp and hot flue gas → ultraviolet instrumentation detection method is directly extracted, this method is due to being to damp and hot cigarette
Gas directly carries out instrument detection, requires higher to instrument and condition, therefore be not suitable for Site Detection；
3. injection finite concentration phosphoric acid solution → condensation drying → detection dress in flue gas (band heating) → pipeline is directly extracted
Method is put, this method suppresses the dissolving of sulfur dioxide in the solution, but titanium dioxide to a certain extent just with the acid of phosphoric acid
The Loss Rate of sulphur component is still higher, and phosphoric acid solution has certain corrosivity, higher to instrument material requirements.
It is clear that above method is not suitable for Site Detection.
