Description
Technical field
The utility model belongs to boiler smoke and administers island desulphurization and denitration, dedusting technology field, and in particular to a kind of wet process is de-
Sulphur dedusting demisting integrated apparatus.
Background technique
In current national economy, power industry is still the discharge rich and influential family of China's atmosphere pollution, wherein flue dust,
SO2、NOx, mercury discharge amount occupy national industry forefront.Develop " 12th Five-Year Plan " planning forecast according to China's Electric Power Industry, to 2020
Year, national capacity of installed generator was up to 18.85 hundred million kW or so, wherein about 11.6 hundred million kW of coal electricity.For many years, China's coal fired power plant
The emphasis of the improvement of atmosphere pollution is flue dust, SO2Deng control, and in recent years since, nitrogen oxides, fine particulates, a huge sum of money
Belong to other pollutant discharge amounts such as mercury to be significantly increased, serious influence also is caused on ecological environment.For the big of China's sternness
Gas pollution control situation, national " 12th Five-Year Plan " planning propose that total emissions of major pollutants is reduced 8% during " 12th Five-Year Plan "
To 10%, and newly-increased NOxThe binding indicator of emission reduction 10%.New " fossil-fuel power plant atmospheric pollutant emission standard "
The emission limit regulation of the pollutants such as coal-fired power plant's flue dust, SO, NO greatly improved in (GB13223-2011) again, and
It has been put forward for the first time the requirement that heavy metal Hg emission limit is lower than 0.03mg/Nm3.On September 12nd, 2014, National Development and Reform Committee, environmental protection
Portion and Bureau of Energy, which combine, has printed and distributed " coal electricity energy-saving and emission-reduction upgrading and transformation action plan (2014~the year two thousand twenty) ", is distinctly claimed
The discharge of coal TV university type boiler smoke need to reach or approach the discharge standard for reaching gas turbine, i.e. " 103550 " standard, wherein SO2
Concentration of emission limit value is 35mg/Nm3, and the emission limit of dust is 10mg/Nm3 (mark condition butt 6%O2), this means that fire coal
Power-plant flue gas must carry out dirt, sulphur, the removing of the multi-pollutants such as nitrogen and mercury simultaneously from now on.
For the discharge of dust, also there are many means at present, and usually before desulphurization system, widespread practice is to take electricity
The techniques such as deduster, bag filter or electric-bag complex dust collector, in these processes, the dust in flue gas are still difficult to meet
Increasingly stringent environmental requirement, and the influence due to desulphurization system absorption tower to flue gas, so that in desulphurization system or system
It takes measures to carry out dust removing again outside just to seem very necessary.After desulphurization system, wet electrical dust precipitator, height are generallyd use
Imitate the means such as mechanical demister, moreover, these means can by with desulfuration absorbing tower being integrated into one structure, formed de-
Sulphur-integrated the equipment of dedusting-demisting.
There is more application using desulfurization-dedusting-demisting integration apparatus of the wet electrical dust precipitator in conjunction with desulfuration absorbing tower
Case, but this technological investment is costly, and construction is big, especially in the project of old tower transformation, due to original tower body
Structure limitation and place situation limitation, this technology is difficult with.
Also had using desulfurization-dedusting-demisting integration apparatus of the efficient mechanical demister in conjunction with desulfuration absorbing tower more
Case, but these cases focus mostly on unit processing exhaust gas volumn it is larger, the occasion that absorption tower is relatively large in diameter, unit handle flue gas
Amount is smaller, when absorption tower diameter is less than 6 meters or less, since demister blocks plate suqare proportion in the flow area of absorption tower
It is gradually increased, the practical flow area of demister is caused to be gradually reduced, demister is deteriorated to the capture effect of drop and dust, will
It is difficult to ensure qualified discharge, is not suitable with small unit dedusting defrosting function, therefore the application of this technology is also subject to certain restrictions.
