Description
Technical field
The present invention relates to a kind of on-Line Monitor Device and its method of PM2.5 industrial smokes, more particularly to the industry such as steel
The purified treatment of metallurgical furnace kiln high-temperature flue gas, belongs to PM2.5 trapping techniques field.
Background technology
PM2.5 refers to particulate matter of the diameter less than or equal to 2.5 μm in air, has the characteristics that particle diameter is small, specific surface area is big,
Easily adsorb poisonous and harmful substances and there is very strong penetration power, bronchiole wall can be arrived at, influence respiratory health, directly endangered
People's health.In China, some essential industry cities, the PM2.5 from steel industry causes people more than three one-tenth
Highest attention.
In PM2.5 cleans dust removal process, how is the uniformity of flue gas duct distribution, directly affects relevant device operation
Efficiency.The flue gas duct of present boiler etc. is distributed common measuring method：Scaffold is set up according to test request in flue,
Major wind turbine puts into operation, and adjusting parameter possesses experimental condition, and tester enters in flue, and hand-held instrument carries out data and adopts
Collection.Because setting up for scaffold and frame plate is more, stream field affects.Tester needs climbing scaffold up and down,
Pointwise test, workload is larger, on-the-spot test bad environments, and wind speed is big, and dust is more, not only endangers tester's health,
Also there are some potential safety problems and detection data it is inaccurate.In field of steel metallurgy, the sintering exhaust gas dust amount that it is produced is big,
Influence wide, temperature is higher, and contains hydrogen chloride（HCl）, oxysulfide（SOx）, nitrogen oxides（NOx）, hydrogen fluoride（HF）Deng corruption
Corrosion gas, flue-gas temperature is generally about 120~180 DEG C.In this case, for dedusting and measurement flue gas duct, smelting
Refinery is also impossible to shut-down (breakdown) mainteance, and the detection of traditional flue gas duct and optimization method are infeasible, this causes metallurgical works
Equipment operating efficiency is not high, its industrial fumes containing a large amount of PM2.5 manufactured can not be efficiently treated.
Although air quality is paid close attention to all the more in the enhancing with common people's health and environmental consciousness, PM2.5 topics are brought rapidly up,
But the research for PM2.5 both at home and abroad is also in the starting stage, except the monitoring to sphere of life PM2.5 has some patents to go out
It is existing, but the features such as metallurgy industry highly corrosive, high temperature, high energy, high speed are combined, specialize in PM2.5 monitorings, the inspection of industrial dedusting
Survey very little with the result of Flow Field Distribution optimization.The prior art does not only exist the monitoring detection architecture imperfection to PM2.5, essence
The problems such as degree is inaccurate, also has that the processing to industrial smoke does not apply to, equipment failure, corrosion resistance is not strong, can not realize intelligence
It can change and the numerous complicated technical barrier such as automate.
At present, the method for measuring flue gas flow field has：（1）Sound wave velocimetry, sound wave are mechanical waves, are propagated in gas medium
When be compressional wave.The velocity of sound is the spread speed of microvariations, is in a fluid linear superposition relation with the flow velocity of medium itself.（2）Survey
Fast pipe determination method, easy to observe and understand the movement locus of air-flow and plasma jet range etc., it can be deduced that the speed field direction of air-flow
Collection of illustrative plates and the velocity amplitude for measuring air-flow everywhere.（3）Hot line/hotting mask velocimetry, the flat of gas is measured using heat balance principle
Equal speed and fluctuation velocity, have the characteristics of inertia is small, and frequency response is wide, high sensitivity, and stream field interference is small.（4）PIV particles
Imaging velocimetry, as a kind of contactless measuring method, can record whole flow field for information about, again in synchronization
Overall structure and the transient images that Plane Fluid Field is shown can be obtained.But above-mentioned each method has the drawbacks of certain, otherwise it is inapplicable
Industrial applications, otherwise accuracy and resolution ratio is not high, it is impossible to meet Ferrous Metallurgy flue gas ash removal and the need of PM2.5 filterings
Ask.
