Description
Technical field
The invention belongs to field of fume treatment equipment, especially relate to a kind of gas cleaning pressure and separate Apparatus for () and method therefor.
Background technology
The industrial gas emission of power plant, chemical plant, cement plant, Industrial Stoves, fuel combustion etc. create a large amount of flue gas, and flue gas is the mixture of gas and flue dust, are the main causes of atmosphere pollution.The composition of flue gas is very complicated, and gas comprises: water vapour, SO
2, N
2, O
2, CO, CO
2, hydrocarbon and oxynitrides etc., flue dust comprises the ash content of fuel, coal grain, oil droplet and high-temperature split product etc., and therefore the pollution of flue gas to environment is the combined pollution of multiple poisonous substance.Flue dust is relevant with the size of particle to the harmfulness of human body, to human body produce harm be mostly that diameter is less than the floating dust of 10 microns, especially with the floating dust of 1-2.5 micron and PM2.5 harmfulness maximum.The bulky grain things such as PM2.5 and PM10 are compared, and fine particle particle diameter is little, are rich in a large amount of poisonous and harmful substances and time of staying is in an atmosphere long, fed distance is far away.Breathing problem can be caused; Carried bacteria, virus cause cancer; Cause cardiovascular and cerebrovascular disease; Thus larger on the impact of health and atmosphere quality.
SO
2, CO, nitrogen oxide etc. pollutes is the main cause causing atmosphere pollution, the SO discharged in a large number during burning
2, cause China to occur large-area acid rain, and development.The acid rain mainly sulfuric acid type of China, caused by anthropogenic discharge's sulfur dioxide, and the water of nitrogen oxide in air is combined and finally can changes into nitric acid and nitrate, nitric acid is also one of origin cause of formation of acid rain, the economic loss that present China causes to aspects such as crops, forest and healths due to the pollution of acid rain is very large, and this has become the key factor of restriction China's economy and social development.Nitrogen oxide can produce photochemical pollution with other pollutant reactions under certain condition, endangers the health of human body.CO is a kind of to blood and the very strong pollutant of nervous system toxicity, carbon monoxide in air, pass through respiratory system, enter in blood of human body, hemoglobin in blood, the myoglobins in muscle, to be combined containing ferrous respiratory enzyme, form reversible bond, significant threat is caused to health.
If directly larger air pollution will be caused in fume emission to air, therefore, will containing SO
2, CO, nitrogen oxide and fine particle fume emission in air before need to carry out purified treatment, can atmosphere pollution be reduced like this, be conducive to the health of human body.So some gas cleaning cleaners arise at the historic moment; In quite a while in the past, electric cleaner plays very important role wherein; But improving constantly of living environment being required along with people, domestic and international environmental protection organization is also corresponding has put into effect new discharge standard, has had 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, the effect of process is all not ideal, also remains harmful gas.Patent document CN201310631871.9 discloses one " flue-gas dust-removing and desulfurization system ", also remain carbon monoxide and these pernicious gases of nitrogen oxide in flue gas after this system does not consider process, cause the flue gas after processing still harmful.
