Description
Technical field
The present invention relates to a kind of horizontal film wet dedusting system of high-efficiency condensation, coal burning boiler of power station flue gas can be widely applied to net
In change processing.
Background technology
The environmental problem that atmosphere pollution is caused is increasingly severe, and control atmosphere pollution thing turns into the common recognition of the whole society, combustion
Coal burning boiler dust emission is the one of the main reasons for causing atmosphere pollution.
At present, existing Wet type electric dust-removing device, is arranged in desulphurization system front portion, due to secondary by efficiency of dust collection, dust
Fly upward and Desulfurization tower slurry carries the influence of factor, its discharge is extremely difficult to minimum discharge requirement；And all rely on electric field
Dust is collected in power effect, and investment is big, and operating cost is high.
The content of the invention
It is an object of the invention to provide a kind of efficiency of dust collection is high, investment and operating cost is low, energy-conservation, gas cleaning, clean
Only the horizontal film wet dedusting system of high-efficiency condensation discharged.
In order to achieve the above object, the horizontal film wet dedusting system of high-efficiency condensation of the present invention, including top connection desulfurizing tower go out
The housing of mouth flue, the flue gas flow equalizing device above enclosure interior, below flue gas flow equalizing device and installed in shell
The flue gas condenser in internal portion, below flue gas condenser and installed in several layers of horizontal diaphragm plate demisting deduster of enclosure interior,
Several flushers on the horizontal diaphragm plate demisting deduster of each layer, installed in horizontal diaphragm plate demisting deduster centre
Collection fluid catheter, the smoke discharging pipe of side below the housing；Described horizontal diaphragm plate demisting deduster, including " mountain " font
The horizontal diaphragm plate of groove, between horizontal diaphragm plate demisting deduster levels, stagger arrangement is horizontally disposed.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, the described horizontal diaphragm plate of " mountain " font groove, its bottom sets interior
Serve as a contrast anticorrosion cloth.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, its operation principle is：First, containing desulfurization slurry and dust
Flue gas enters flue gas condenser via flue gas flow equalizing device, is exchanged heat in flue gas condenser with condenser pipe, flue-gas temperature drop
Low, after the reduction of saturated flue gas temperature, water smoke is separated out and is attached on dust, dust is coated and is grown up by drop, due to condensation
Pipe streams generation vortex street effect, dust-containing liquid drop in this also frequent impact, coalescence, grow up, it is favourable to be that further dedusting demisting is created
Condition.Then, the flue dust of Caragana seed pests enters horizontal diaphragm plate demisting deduster, including the horizontal diaphragm plate of " mountain " font groove, and horizontal diaphragm plate is removed
The operation starting stage of mist deduster forms in moisture film, running the water tariff collection water absorbed in flue gas by flusher
Film, slurries, the dust that moisture film is met in flue gas flow direction arrangement, flue gas is adsorbed when hitting moisture film by it, due to " mountain " of horizontal diaphragm plate
Character form structure, flue gas forms vortex on horizontal diaphragm plate, advantageously in the absorption of moisture film.Finally, the dust-laden drop after absorption is made
For
Moisture film continues to absorb follow-up dust-laden drop, and the flusher opened by interruption pours collection fluid catheter, flows into de-
Sulphur slurry pool, meanwhile, the flue gas after purification is discharged from smoke discharging pipe, gas cleaning, clean emission.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, described horizontal diaphragm plate demisting deduster, between levels, its
Horizontal diaphragm plate is staggered in arrangement.Flue gas flows through multilayer moisture film, and slurries are constantly absorbed, and flue gas is effectively purified.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, horizontal diaphragm plate bottom portion of groove sets lining anti-corrosion cloth, by cloth
Capillary properties, make moisture film uniform, it is to avoid fouling.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, every piece of horizontal diaphragm plate is equipped with flusher, for originating operation
Moisture film and the flushing to collection liquid are formed, fouling is prevented.Interruption flushing is carried out to horizontal diaphragm plate, protected while removing slurries and dust
Hold continuous moisture film.
Dust-laden particle and slurries in the horizontal film wet dedusting system of high-efficiency condensation of the present invention, flue gas stream the horizontal diaphragm plate of stagger arrangement,
During streaming, moisture film is directly hit with air-flow, can be absorbed by the efficient moisture film of horizontal diaphragm plate, efficiency of dust collection is high.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, because dust drives without electric field force, unpowered system, investment
And operating cost is low, energy-conservation, good operation stability is safe and reliable.
The horizontal film wet dedusting system of high-efficiency condensation of the present invention, is arranged in desulfurizing tower exhaust pass, is sprayed by flusher
And the moisture absorbed in supersaturated flue gas forms moisture film in horizontal diaphragm plate bottom, moisture film is perpendicular to flue gas flow direction, and it is to collect that it, which is acted on,
The slurries and dust carried after desulfurization in wet flue gas, purifying smoke reaches ultra-clean emissions object.
In summary, the horizontal film wet dedusting system of high-efficiency condensation of the present invention, efficiency of dust collection is high, and investment and operating cost are low,
Energy-conservation, gas cleaning, clean emission.
