Description

The electrostatic degree of depth dust arrester of desulfurizing tower
Technical field
The utility model relates to electrostatic wet sprinkling dedusting under a kind of desulfurizing tower top high-voltage environment or demister.
Background technology
Current, tower inner high voltage wet static dedusting (mist) device is meeting the Be very effective in minimum discharge, improvement PM2.5, national environmental protection portion explicitly points out in " surrounding air fine particle pollution prevention technique policy (trying) " (exposure draft): encourage Thermal Power Enterprises to adopt the new technologies such as tower inner high voltage wet static dedusting (mist), " gypsum rain " preventing desulfurization from causing pollutes.
Summary of the invention
For realizing tower inner high voltage wet static dedusting, meet the requirement of minimum discharge, the utility model provides the electrostatic degree of depth dust arrester of a kind of desulfurizing tower, and its technical scheme taked is:
Comprise cylindrical shell, upper hanging beam, lower hanging beam, circular fixed frame, airflow uniform distribution plate, spray equipment and insulated porcelain sleeve, the top in housing is located at by spray equipment, the bottom in housing is located at by airflow uniform distribution plate, upper hanging beam and lower hanging beam are laterally fixed on the upper and lower in housing respectively, insulated porcelain sleeve is eight, four tops being evenly fixed on hull outside wall, their bottom connects hanging beam respectively, all the other four bottoms being evenly fixed on hull outside wall, their bottom connects lower hanging beam respectively, each insulated porcelain sleeve is covered with incubator, upper hanging beam and lower hanging beam are fixed with cathode line arranged vertically respectively, fixed frame is located at the middle part in housing, fixed frame is fixed with anode tube arranged vertically, each anode tube cross section is regular hexagon, line up honeycomb each other, cathode line is corresponding with anode tube, every root cathode line runs through at anode tube axis direction.
Flue gas flows through anode tube from lower to upper in electric field region, and in the ionization space that anode tube and cathode line form, charged dust (cloud), by electrostatic force, is adsorbed on anode tube inwall, thus reaches dedusting (mist) effect.This device adopts current to rinse, and does not have rapping apparatus, can not produce reentrainment of dust, and to acid mist, toxic heavy metal and PM10, especially the fine dust of PM2.5 has and good deviates from effect.The electrostatic degree of depth dust arrester of desulfurizing tower can solve gypsum rain, the blue smoke problem that wet desulphurization brings, and alleviates the corrosion of downstream flue, chimney, saves anticorrosion cost.It is stable and reliable for performance, efficiency is high, and can effectively collect fine particle, heavy metal, organic pollution etc., soot emissions can reach 10mg/m3 even below 5mg/m3, realize minimum discharge, thoroughly solves smoke stack emission problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the B-B of Fig. 1 is to top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As depicted in figs. 1 and 2, the top in cylinder shell 1 is located at by spray equipment 3, the bottom in housing 1 is located at by airflow uniform distribution plate 9, upper hanging beam 4 and lower hanging beam 10 are laterally fixed on the upper and lower in housing 1 respectively, insulated porcelain sleeve 8 is eight, four tops being evenly fixed on housing 1 lateral wall, their bottom connects hanging beam 4 respectively, all the other four bottoms being evenly fixed on housing 1 lateral wall, their bottom connects lower hanging beam 10 respectively, each insulated porcelain sleeve 8 is covered with incubator 2, insulated porcelain sleeve 8 provides electric power for electric field dedusting area, wherein incubator 2 is protected insulated porcelain sleeve 8 and is heated, insulated porcelain sleeve 8 is communicated with electric field, and insulate with build up outside and isolate.Upper hanging beam 4 and lower hanging beam 10 are fixed with cathode line 5 arranged vertically respectively, fixed frame 7 is located at the middle part in housing 1, its cross section cross, fixed frame 7 is fixed with anode tube 6 arranged vertically, each anode tube 6 cross section is regular hexagon, line up honeycomb each other, cathode line 5 is corresponding with anode tube 6, and every root cathode line 5 runs through at anode tube 6 axis direction.
Between positive plate 6 and cathode line 5, apply tens thousand of volt DC high-voltage, under the effect of highfield, there is fully ionization in the gas of negative and positive two interpolar, makes working space be full of the ion being with positive and negative electric charge.Air-flow flows from bottom to top, air-flow is after the current-sharing of uniform board 9, be with in the electric field of cathode line 5 and anode tube 6 formation, subsequently with there is the positive and negative ion that ionizes and to collide and charged, charged dirt (mist) particle, owing to being subject to the effect of Coulomb force, high-voltage electrostatic field, moves respectively to cathode and anode; After arriving two-stage, respective be with electric charge is discharged, dirt (mist) grain itself is then attached in positive plate 6 and cathode line 5 due to its intrinsic stickiness, spray equipment 3 is vertical corresponding with anode tube 6, by to immediately below anode tube 6 sidewall spray umbrella water curtain, wash away the dust being attached to anode tube 6 inwall, dust-laden current are flowed downward along inwall, finally enter in desulfurizing tower below this device or ash silo.
