Description
Technical field
The present invention relates to a kind of square chest type desulfurizing tower high-effective dust-removing current equalizers.
Background technology
As China's economic continues to develop, electricity needs persistently increases, haze long lasting effect, and control PM2.5 refers to discuss
Thing schedule.Local government, electric power enterprise propose that " minimum discharge ", " near-zero release ", " reach combustion engine discharge standard " build one after another
If or transformation requires." minimum discharge " technology, the discharge of scientific guidance Thermal Power Generation Industry sustainable development ultra-clean.
State Development and Reform Commission prints and distributes《Coal electricity energy-saving and emission-reduction upgrade and transformation action plan (2014-2020)》Air of keeping under strict control is dirty
Contaminate object discharge.Newly-built Thermal generation unit (being contained in the unit built and be included in national construction of fire and electricity planning with project) answers synchronized construction
Gas bypass channel must not be arranged in advanced high-efficiency desulfurization, denitration and dust removal installation.Eastern region (Liaoning, Beijing, Tianjin, river
11 provinces and cities such as north, Shandong, Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, Hainan) create Thermal generation unit Air Pollutant Emission
Concentration basically reach gas turbine group emission limit (i.e. under the conditions of benchmark oxygen content 6%, flue dust, sulfur dioxide, nitrogen oxides
Concentration of emission is respectively no higher than 10,35,50 milligrams/cubic metre).Middle part (Heilungkiang, Jilin, Shanxi, Anhui, Hubei, lake
8 province such as south, Henan, Jiangxi) new-built unit is close to or up to gas turbine group emission limit in principle.Encourage west area newly-built
Unit is close to or up to gas turbine group emission limit, supports synchronous atmosphere pollution combination and cooperation of carrying out to remove, reduces by three oxygen
Change the pollutant emissions such as sulphur, mercury, arsenic.In traditional flue gas desulphurization system, desulfurization discharge efficiency is less than 95%, and desulfurization outlet drain is
Flue dust, sulfur dioxide emissioning concentration are respectively greater than 20,100 milligrams/cubic metre, and there are no reach minimum discharge requirement (flue dust, two
Sulfur oxide emissions concentration is respectively no higher than 10,35 milligrams/cubic metre).Existing apparatus is in desulfurization entrance SO2Concentration 3420mg/Nm3
When, desulfurization entrance dust concentration is 24mg/Nm3When, desulfurization exports SO2A concentration of 180mg/Nm3, outlet dust concentration is 20mg/
Nm3, desulfuration efficiency 95%, desulfurizer exiting flue gas amount is 246200Nm3/h.Existing desulfurization equipment cannot be satisfied super
Low emission exports sulfur dioxide (SO2) < 20mg/Nm3, outlet dust concentration be 5mg/Nm3Emission request, i.e., existing desulfurization system
System cannot meet minimum discharge operation emission request, therefore need to be transformed to generator set desulfurization reaction unit.

Further, the steel plate thickness is 3mm.
Further, the triangle anti-gray board bottom portion is fixed on I-beam.
Further, four angles of the dedusting current equalizer are separately fixed on the pillar of desulfurizing tower.
Further, the intersection bottom of the dedusting current equalizer and desulfurizing tower surrounding siding is equipped with I-beam.
Further, it is equipped with the anti-hawk of triangle every the junction of 1,2,3 or 4 arc dedusting homogenizing plate module.
Beneficial effects of the present invention are：
Square chest type desulfurizing tower high-effective dust-removing current equalizer of the present invention makes more equal into desulfurization tower flue gas flow distribution
It is even, it is more uniformly distributed, is can guarantee in desulfurization entrance SO with improving gas-liquid contact2A concentration of 3420mg/Nm3When, desulfurization entrance flue dust is dense
Degree is 24mg/Nm3When, reach desulfuration efficiency not less than 99% and desulfurization exports SO2Concentration is not more than 20mg/Nm3, export flue dust
A concentration of 5mg/Nm3Emission request optimizes design, reduces cost, plays energy saving and cost lowering synergistic effect, has great
Economic implications.
Dedusting current equalizer of the present invention in desulfurizing tower gas-liquid by when, it is mixed to generate violent disturbance in the device
It closes, gas-liquid can be made to form superposed layer on device top, to increase gas-liquid contact surface area, extend slurries residence time and reaction
Time keeps flue gas and slurry liquid contacts surface more abundant, and to make desulfuration efficiency be improved 4%~5%, arc dedusting is flowed
Plate module can be adsorbed on flue dust in desulfurizing tower is entered in arc groove, is formed dust mucous layer, is passed through (the punching of spraying layer above
Wash water) spray irrigation fall into slurry pool, achieve the purpose that dedirt.
The disturbance that dedusting current equalizer air-flow of the present invention is rotated makes gas-liquid more come into full contact with increase desulfurization anti-
Answer area, at the same in gas-liquid flue dust and gypsum slurries remove, reach dedusting purpose.
Dedusting current equalizer of the present invention is high with desulfuration efficiency, low energy consumption, resistance small (resistance only has 150Pa), knot
The advantages that structure is simple, maintenance is easy to maintenance, the newly-built desulfurizing item and desulfurization renovation and improving item of the middle and high sulphur coal that is suitable for burning
Mesh.The dedusting current equalizer keeps flue gas flow field distribution more uniform, and unbiased flow short-circuit dead zone, resistance is low, makes flue gas flow field point
Cloth is more uniform, and no bias current, resistance is low, alleviates the abrasion of upstream device, extends service life.
