Description
Technical field
This utility model relates to flue gas advanced purification technology field. More particularly, to a kind of adjustable corona discharge electrode and with the electrostatic precipitation demister of adjustable corona discharge electrode.
Background technology
At present, China flue gas or industrial tail gas pollutant abatement technology are more, and wherein comparative maturity, representative technology have: administer sulfur dioxide (SO2) pollute limestone-gypsum method, ammonia process, the Wet Flue Gas Desulfurization Technique such as Dual alkali.
In Wet Flue Gas Desulfurization Technique, spray washing is both needed to install demister and removes the fine droplet produced in spray process after purifying; With regard to current practical situation, it is no matter Flat defroster or ridge type demister to dust less than 5 ��m of the diameter drop less than 5 ��m and diameter and constitutes the clearance of the finely ground particles such as the aerocolloidal sulfate radical of PM2.5, inferior sulfate radical, nitrate anion, nitrite anions and be extremely difficult to environmental requirement.
For meeting more and more strict environmental requirement, wet desulphurization device rear end is both needed to install wet electrical dust precipitator additional and carries out appropriateness purification. Although wet-esp can effectively remove finely ground particles, but it is it is generally required to after being arranged on conventional demister, as designed with tower integrated desulfurizing, need higher space, and because requiring that flue gas low flow velocity runs, thus must expand on desulfurizing tower tower diameter basis, say, that wet-esp also exists process equipment both bulk, the problem that desulfurizing tower tower wall and basis are both needed to strengthening reconstruction; After being individually arranged in absorption tower, there is again the big problem that takes up room; So the transformation difficulty installing wet-esp equipment on constructed item additional is big.
Additionally wet cottrell initial cost is high, operation energy consumption is high, and repair and maintenance workload is big, and operation maintenance Personnel Skill Levels requires height.
For solving the problems referred to above, occur in that Multi-stage spiral dedusting demister and multistage double-cyclone dedusting demister technology. But there is the problem limited by exhaust gas volumn size in these technology, for instance, when exhaust gas volumn is far below design load, it is impossible to have good dedusting except fog effect; It addition, spiral-flow type dedusting is not good to the removal effect of aerosol etc. except mist.
For this, occur in that again electromechanical integration dedusting is except mist new technique.This technology is combined as a whole by rotational flow dust-removing demister and wet cottrell, when party's exhaust gas volumn is close to design load, relies primarily on rotational flow dust-removing except mist, and wet cottrell is used only as removal SO3Deng aerosol; When exhaust gas volumn is relatively low, flue gas flow rate is relatively low, and relatively low exhaust gas volumn and flow velocity are the optimum conditions of wet cottrell work, therefore, in the case, wet cottrell will give full play to dedusting except the effect of mist, thus whole device dedusting will not decline except the efficiency of mist.
But the fixing suspension in the current art of wet cottrell, corona wire or top, bottom weight-adding hammer and location, or it is arranged in fixed frame. When this technology makes to install corona wire, the two ends of corona wire are both needed to leave bigger space, and this requirement makes the wet cottrell using corona wire be difficult to really be combined as a whole with rotational flow dust-removing demister.
And abandon the two ends mounting means that corona wire is traditional, only by one end stationary positioned, one end stationary positioned it is accomplished by increasing substantially the rigidity of corona wire, namely strengthens the diameter of corona wire, such that it is able to only can ensure that rocking in allowed limits of the corona wire that is in operation. But corona wire generally uses metal costly, and after dilated diameter, consumptive material is greatly improved, investment rises; Its two, strengthen after corona wire wire diameter, for ensureing its corona effects, it is necessary to being processed its surface processing, workload is big; It addition, after corona wire increasing, weight is also greatly improved so that the device fixing it also must strengthen, and also improves investment, also results in load and strengthen, affect the structure of whole device.
