Description
The utility model belongs to the udst separation field, is specifically related to a kind of multi-cyclone, static combined type deduster.
At present normally used in the soot emissions field have bag-type dust, water film dedusting, cyclone dust removal and an electrostatic precipitation etc.Sack cleaner is fragile, the life-span is short, maintenance cost is high.Water film dedusting efficient is low, and has the secondary pollution problem, and single tube cyclone dust removal efficient is low, is difficult to reach the environment protection emission requirement.The disclosed a kind of electrostatic precipitator of Chinese patent CN2061483U, to be diameter wash away metal sheet surface greater than the grit of 5 μ to its shortcoming, easily cause wearing and tearing, thereby reduce service life, owing to there is not pre-dedusting, dust content is big, required cathode line and the corresponding increase of anode collecting plate area, so one-time investment is also bigger.
The purpose of this utility model is to provide a kind of small investment, low, the long service life that consumes energy, and good dedusting effect, operating maintenance be high-efficiency dust remover easily.
The technical solution of the utility model is:
This deduster adopts the multi-cyclone dedusting as first order dedusting, removes the grit of diameter greater than 5 μ.Adopt electrostatic precipitation as second level dedusting, remove the grit of diameter less than 5 μ.Integral structure is adopted in the two poles of the earth dedusting, organically is combined into an integral body, becomes efficient multi-cyclone, static combined type deduster.Primary dust removing of the present utility model is by entrance sleeve, a plurality of adjustable by-pass valve, compositions such as multi-cyclone, ash bucket.After connect two-stage dust removal, it is by import current-sharing catching sheet, middle part current-sharing catching sheet, outlet current-sharing catching sheet, negative electrode, anode dust-catching board, compositions such as discharge connection, ash bucket.Its course of work is: when having higher dustiness, and degree different gas in grit footpath at first enters the multi-cyclone dust removal part from entrance sleeve when discharging, and make the air-flow current-sharing through regulating by-pass valve, but air flow rate use traffic meter detects at each valve place.After the current-sharing, air-flow enters multi-cyclone, because the inertia force effect, rotation is reaching centrifugation in the sub-pipe of whirlwind, and diameter is separated greater than the grit of 5 μ and falls into ash bucket.Diameter enters the electrostatic precipitation part less than the grit of 5 μ with air-flow.Through the current-sharing catching sheet, reduced flow velocity, further make airflow uniform distribution.Because the discharge of prickle shape minus plate makes negative electricity on the grit band, under the electric field force effect, electronegative grit is adsorbed on by the anode dust-catching board, falls into ash bucket after the grit vibration that is captured.Reach discharging standards after making the higher air-flow purified treatment of dust content like this.
Advantage of the present utility model is: 1. adopt multi-cyclone and high-pressure electrostatic composite dedusting, integrate both advantages, solved the disadvantage of general deduster, obtained best dust removing effects, dust removal efficiency reaches 99.7%, meets or exceeds discharging standards, and remarkable economical and social benefit are arranged.2. owing to adopted cyclone pre-dusting, remove big dust particle, reduced the friction of coarse granule in equipment, prolonged the life-span of electric cleaner.3. owing to alleviated the burden of electrostatic precipitation, the electrostatic precipitation partial volume is reduced, power consumption is few, and cost reduces than independent electrostatic precipitation cost.4. equipment overall structure compactness, both adopt integral structure, have reduced unnecessary transition and have connected.5. owing to reduced coarse granule content, reduce friction, prolonged the service life of impeller.6. whole system is consistent, non-secondary pollution, and the operation maintenance is convenient.7. be provided with adjustable by-pass valve at the air intake pipe orifice place,, solved the unbalanced problem of device efficiency in each practicable multimetering in import position.
The utility model has following accompanying drawing:
Fig. 1 is the utility model front view;
Fig. 2 is the utility model vertical view;
Fig. 3 is for importing and exporting the current-sharing catching sheet;
Fig. 4 is horizontal frid side view.
Embodiment:
With reference to accompanying drawing 1,2,3,4, air inlet 1 joins with boiler chimney, and the other end is connected with multicyclone 2,22 whirlwind 15 are installed in the cyclone dust collectors 2, in the sub-porch of whirlwind 3 by-pass valves 13 are installed, are made the air-flow current-sharing, and the utilizable flow meter detects and adjusting makes air-flow even.Whirlwind 15 end openings and ash bucket 14 join, and dust falls into ash bucket 14 at gravity, centrifugal action.Electrostatic precipitator is installed on the column 11, and multicyclone 2 and electrostatic precipitator 3 link to each other by current-sharing catching sheet 12, and the different aperture of some diameters 16 is arranged on the current-sharing catching sheet, make air-flow even once more.Laterally frid 9 is installed together at the middle part of electrostatic precipitator, current-sharing catching sheet structure is installed with 12 before air outlet 10, the bottom of electrostatic precipitator 3 is an ash bucket 14, the top of electrostatic precipitator 3 is insulator chamber 6, insulator wherein is installed is hung 7, mount prickle shape negative electrode 5 and anode dust-catching board 4 below insulator hangs 7, they alternately as shown in Figure 2, access door 8, easy access are installed on insulator chamber 6 lateral walls.The utility model can be widely used in that coal-burning boiler, cement, tobacco, metallurgy etc. have the depollution of environment in the soot emissions field and flue dust reclaims.
