Description
Technical field
The invention belongs to field of fume treatment equipment, more particularly, to a kind of gas cleaning pressure solution device and method thereof.
Background technology
Power plant, chemical plant, cement plant, the industrial gas emission of Industrial Stoves, fuel combustion etc. generate a large amount of flue gases, cigarette
Gas is the mixture of gas and flue dust, is the main cause for polluting air.The composition of flue gas is very complicated, and gas includes:Water steams
Vapour, SO2、N2、O2、CO、CO2, hydrocarbon and oxynitrides etc., flue dust include the ash content of fuel, coal grain, oil droplet with
And high-temperature split product etc., therefore pollution of the flue gas to environment is the combined pollution of a variety of poisonous substances.Harmfulness of the flue dust to human body
Relevant with the size of particle, it is that diameter is less than 10 microns of floating dust that the mostly of harm are produced to human body, is especially floatd with 1-2.5 microns
Dirt is that PM2.5 harmfulness is maximum.PM2.5 is compared with the bulky grain thing such as PM10, and fine particle particle diameter is small, rich in it is substantial amounts of it is poisonous,
Harmful substance and residence time length, fed distance in an atmosphere is remote.Breathing problem can be triggered;Carried bacteria, virus cause
Cancer;Trigger cardiovascular and cerebrovascular disease;Influence thus to health and atmosphere quality is bigger.
SO2, CO, the pollution such as nitrogen oxides be the main cause for causing atmosphere pollution, the SO largely discharged during burning2, cause
There is the acid rain of large area in China, and continues to develop.The acid rain of China is mainly sulfuric acid type, is made by anthropogenic discharge's sulfur dioxide
Into, and nitrogen oxides is combined with the water in air and eventually changes into nitric acid and nitrate, nitric acid is also one of origin cause of formation of acid rain,
Present China is very big to the economic loss caused in terms of crops, forest and health due to the pollution of acid rain, and this is
Key factor as restriction China's economy and social development.Nitrogen oxides can be produced with other pollutant reactions under certain condition
Raw photochemical pollution, endangers the health of human body.CO be it is a kind of to blood and nervous system toxicity very strong pollutant, it is empty
Carbon monoxide in gas, by respiratory system, into blood of human body, with the hemoglobin in blood, the flesh red eggs in muscle
In vain, combined containing ferrous respiratory enzyme, form reversible conjugate, significant threat is caused to health.
If fume emission directly will be caused larger air pollution into air, therefore, SO will contained2, CO, nitrogen
The fume emission of oxide and fine particle needs to carry out purified treatment before into air, can so reduce air dirty
Dye, is conducive to the health of human body.So, some gas cleaning cleaners arise at the historic moment;In the past quite a while,
Electric cleaner plays critically important role wherein;The continuous improvement required however as people living environment, both at home and abroad
Environmental protection organization has also accordingly put into effect new discharge standard, has higher requirement to the control of pollution sources.
But, current flue-gas purification treatment device obtains not thorough to the pollutant process in flue gas, and the effect of processing is equal
It is not ideal, also remain harmful gas.Patent document CN201310631871.9 discloses a kind of " flue gas ash removal
Desulphurization system ", the system considers also to remain carbon monoxide and nitrogen oxides in the flue gas after processing that these have
Evil gas, causes the flue gas after processing still harmful.
