Sinter-plate Filter
Technical field
The utility model relates to deduster technical field, especially a kind of Sinter-plate Filter.
Background technology
Deduster just occurs in Japan and more American-European countries as far back as 20 century 70s, there is volume little, efficiency is high, reduced investment, the advantages such as easy care, but because its place capacity is little, difficulty is combined into Wind Volume equipment, and filtration velocity is on the low side, and range of application is narrow, only in the sector application such as grain, welding, so fail large-scale popularization for many years.In recent years, along with new technology, new material constantly develop, with Japan, the company of the U.S. is representative, the structure of deduster and filtrate are improved, make deduster be widely used in the industrial circles such as cement, iron and steel, electric power, food, metallurgy, chemical industry, whole volume increases several times, becomes filter area >2000m
2large-scale deduster, be solve traditional deduster to ultrafine dust collect difficult, filtration velocity is high, ash-removal effect is poor, filter bag run-down, preferred plan that operating cost is high easy to wear, compare with various pocket type existing on market, electrostatic precipitator have that effective filtration area is large, pressure reduction is low, the feature such as low emission, volume are little, long service life, become the new direction of industrial dust collector development.Traditional deduster complex structure, install and keep in repair loaded down with trivial details, dust removing effects is poor.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Sinter-plate Filter as shown in Figure 1, comprise dust collector box body 1, dust collector box body 1 comprises the toilet 3 and filter chamber 4 of being separated by card 2, toilet 3 is positioned at above filter chamber 4, card 2 hangs four sintered plate filter cores 7 are installed, toilet 3 sidewall offers the gas outlet 6 of clean gas, and filter chamber 4 sidewall offers the air inlet 5 that dusty gas enters; Be connected with taper ash bucket 10 below filter chamber 4, ash bucket 10 sidewall is provided with pneumatic hammer 11, is provided with ash hole 8 bottom ash bucket 10; Sintered plate filter core 7 outer surface is provided with thickness transducer 17, and thickness transducer 17 is by being wirelessly connected with PLC 18; Toilet 3 sidewall is provided with pulse ash remover.
Pulse ash remover comprises the gas storage bag 13 being arranged on toilet 3 sidewall, gas storage bag 13 is connected with pulse valve 14 and deashing pipe 15, and deashing pipe 15 is provided with four injection tubes 16, and each injection tube 16 is positioned at directly over sintered plate filter core 7 opening; Pulse valve 14 is by being wirelessly connected with PLC 18.
Ash hole 8 place is provided with ash-valve 12; Below filter chamber 4, four angles are provided with the supporting leg 9 of dismounting; Thickness transducer 17 is positioned in the middle part of sintered plate filter core 7.
Filtration condition: dusty gas enters behind filter chamber 4 through air inlet 5, due to the sudden enlargement of air-flow section, in air-flow, a part of big particle is moving and is being deposited in ash bucket 10 under inertia force effect; After the grit that fine size, density are little enters filter chamber 4, by combined effects such as Blang's diffusion and sievings, make dust deposit at sintered plate filter core 7 on the surface, purified gas enters toilet 3 and is discharged by gas outlet 6.
Deashing state: when thickness transducer 17 detects that sintered plate filter core 7 dust thickness reaches setting value, signal is delivered to PLC 18, PLC 18 control impuls valve 14 is opened, compressed air in gas storage bag 13 is through deashing pipe 15, spray instantaneously from injection tube 16, under the effect that sintered plate filter core 7 is washed away at inverted draft, the dust be attached on sintered plate filter core 7 outer surface is stripped and falls into ash bucket 10.After deashing, pulse valve 14 cuts out, and filtration condition recovers again in filter chamber 4.The dust come off is fallen in ash bucket 10 and is discharged by ash-valve 12.Because ultrafine dust viscosity is very large, is attached to ash bucket 10 inwall and easily blocks, therefore at ash bucket 10 side plate, pneumatic hammer 11 is installed, dust is discharged smoothly.
This Sinter-plate Filter structure is simple, reasonable in design, easy to operate, sintered plate filter core 7 filtering accuracy is high, the highlyest filter 0.1 μm of dust, for the dust catching efficiency of more than 1 μm up to 99.99%, concentration of emission is minimum reaches 1mg/m3, and sintered plate has according to oil according to water function, oil-containing 5%, all can normally work under the operating mode of moisture 10% (volume ratio), but common filter bag or filter cartridge dust remover then cannot, easily cause paste bag.
The utility model has the advantage that ash-removal effect is good, purification efficiency is high, process air quantity is large, sintered plate filter core 7 life-span is long, maintenance load is little, safe and reliable to operation.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
