Description
Technical field
This utility model relates to filed of flue gas purification, and the particularly multi-pollutant such as fine particle dust, PM2.5 works in coordination with the electrostatic fabric filter of process.
Background technology
Along with China's economy grows continuously and fast, urbanization and process of industrialization are accelerated day by day, and various atmosphere pollutions sharply increase.PM2.5 as the focus that recently country pays close attention to, is one of main pollutant of air.PM2.5 content in an atmosphere is seldom, but little because of its particle diameter, and specific surface area is big, so it is long with harmful substance and atmospheric residence time to be adsorbed with a large amount of virus, difficulty is removed, and amblent air temperature change, air quality and health are suffered from material impact.Owing to the main source of PM2.5 is the discharge of mankind's activity, therefore, PM2.5 may be adsorbed with the carcinogen such as heavy metallic oxide or polycyclic aromatic hydrocarbon so that it is effect toxic to environment and human body.
At present, conventional high-efficiency dust remover can not effectively trap for particle diameter particle between 0.1～2.0 μm.Traditional electrostatic precipitator can reach more than 99% for granule dedusting efficiency more than 10 μm, but when particulate matter diameter is less than 2 μm, efficiency of dust collection will be remarkably decreased, and efficiency of dust collection even can drop to less than 50% less than 90%.And bag dust collector has higher removal efficiency to particle diameter less than the particulate matter of 2.5 μm.Electrostatic fabric filter combines electric precipitation and the advantage of bag dedusting, first passes through electric precipitation removing bulky grain, then removes fine particle by bag-type dust, reduces cloth bag workload, the service life of extension device.But electrostatic fabric filter of the prior art, air flow method is uneven, and load adaptability is poor, the highest to PM2.5 removal efficiency.And the change of existing resistance of the filter bag is unstable, the filtering accuracy of filtrate is the highest, affects the service life of filter bag.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electrostatic fabric filter removing PM2.5.It can improve cleaner unit flow field, alleviates the dust abrasion to filter bag, extends life of bag filter, and improves efficiency of dust collection further.
In order to reach foregoing invention purpose, the technical solution of the utility model realizes as follows:
Can remove the electrostatic fabric filter of PM2.5, it includes the electric precipitation in casing, casing and the bag-type dusting structure being made up of air-purifying chamber and filter bag below.Electric precipitation connects air inlet, and air-purifying chamber connects gas outlet.Being provided with polar curve in electric precipitation, be equipped with pulse valve above air-purifying chamber, be equipped with ash bucket below casing, whole casing is supported by support is fixing.It is structurally characterized in that, is provided with the dividing plate being disposed vertically in described casing between electric precipitation and air-purifying chamber, and dividing plate is provided with the perforate being evenly arranged.Described filter bag coating composition is 65% ultra-fine PPS fiber and 35%PTFE fiber, and base fabric is PTFE.
In above-mentioned electrostatic fabric filter structure, the material of described dividing plate is rustless steel, and percent opening is 50%.
This utility model has the following advantages and beneficial effect compared with the prior art:
1) dividing plate uses stainless steel, and uniform pore openings is also staggered in arrangement, beneficially air-flow is uniformly distributed, and improves cleaner unit flow field, it is to avoid in prior art, air flow method is uneven, the problem of load adaptability difference, improves PM2.5 removal efficiency.
2) change of filter bag composition makes specific surface area increase, it is possible to increase the filtering accuracy of filtrate, reduces the concentration of emission of dust, and the especially discharge of fine particle, fiber finer and quantity is many, intercepts the effective of dust.Internal structure is fine and close, and dust is not easy to go deep into inside filtrate, and equipment resistance change is steady, beneficially the removing to PM2.5, and effectively extends the service life of filter bag, meets emission request.
3) big particle in exhaust gas dust is after the sedimentation of prime electric field and pre-dedusting, and the dust granules entering rear class filter bag is little, reduces filter bag workload, extends the cleaning cycle of filter bag, saves deashing energy consumption.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model median septum.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, this utility model can remove the electrostatic fabric filter of PM2.5, and it includes the electric precipitation 2 in casing 12, casing 12 and the bag-type dusting structure being made up of air-purifying chamber 6 and filter bag below 8.Electric precipitation 2 connects air inlet 1, and air-purifying chamber 6 connects gas outlet 7.Being provided with polar curve 3 in electric precipitation 2, be equipped with pulse valve 5 above air-purifying chamber 6, be equipped with ash bucket 9 below casing, whole casing is supported by support 10 is fixing.Being provided with the stainless steel separator 4 being disposed vertically in casing 12 between electric precipitation 2 and air-purifying chamber 6, dividing plate 4 is provided with the perforate 11 being evenly arranged, and percent opening is 50%.Filter bag 8 coating composition is 65% ultra-fine PPS fiber and 35%PTFE fiber, and base fabric is PTFE.
When this utility model runs, from the flue gas of boiler emission after denitrification apparatus, air inlet 1 enter electric precipitation 2.Realizing the trapping of major part dust in electric precipitation 2, the dust of trapping is attached on the polar curve 3 of electric precipitation 2, and purge mode is sidepiece mechanical vibrator.Flue gas after electric-type dedusting flows through stainless steel separator 4, and enters bag-type dusting structure.Being intercepted by filter bag 8 and collect the dust of surplus in flue gas, dust is stayed filter bag 8 outer surface and is formed ash cake layer.When ash cake layer reaches certain thickness or time, pulse valve 5 starts, and carries out low-pressure pulse rotary jetting deashing, and the dust fallen clearly falls in the ash bucket 9 of lower box, and the flue gas after purification is through air-purifying chamber 6, and is discharged by gas outlet 7.
