Description

Electric-bag complex dust collector
Technical field
The utility model relates to a kind of fume dust remover, particularly a kind of electric-bag complex dust collector.
Background technology
In industrial processes, in thermal power generation, manufacture of cement, metallurgy industry, usually can produce a large amount of dusty gases.These contain a large amount of dusty gas discharged to atmosphere before, must purify by dust arrester.
At present, the industrial smoke dust arrester mainly is divided into electrostatic precipitator and sack cleaner.Electrostatic precipitator is to make dust charged in electric field, and deposits to dust collection plate under the effect of electric field force; It has the advantages such as the smoke treatment amount is large, running resistance is low; But the efficiency of dust collection of electrostatic precipitator is vulnerable to the impact of exhaust gas dust characteristic and fluctuates, and smoke emissioning concentration is difficult to up to standard.Sack cleaner is to filter flue gas by filter bag to purify, and it is not subjected to the dust properties influence, good dedusting effect, and concentration of emission is low; But exist that SR is large, energy consumption is high, filter bag rapid wear, deficiency that operation and maintenance cost is high.
Because electrostatic precipitator and sack cleaner cut both ways, the electric-bag complex dust collector that above-mentioned both advantages are got up has just arisen at the historic moment.Existing electric-bag complex dust collector normally front portion is that electrostatic precipitation district, rear portion are the bag dedusting area; At first charged in the electrostatic precipitation district and the major part of dust in the flue gas is collected, the dust that is not collected then enters the bag dedusting area at rear portion with upper electric charge, be attached on the filter bag in order and loosely, thereby the flow resistance of reduction flue gas improves the efficiency of dust collection of bag dedusting.Yet in practical work process, because flue gas time of staying in the electrostatic precipitation district is shorter, the part dust also has little time charged; Simultaneously because the front and back of electrostatic precipitation district and bag dedusting area arrange so that charged dust from anterior electrostatic precipitation district to the rear bag dedusting area than losing electric charge the growth process, again become neutral dust, therefore the drag reduction of bag dedusting is limited.
Chinese patent ZL200910261104.7 discloses a kind of electric-bag complex dust collector that comprises electricity bag mixed zone, wherein, electricity bag mixed zone is comprised of some filter bag rows and some electric field passages, each filter bag row arranges at parallel and interval substantially with each electric field passage, has row's filter bag among the filter bag row at least, the electric field passage has two positive plates at least, and the gap between adjacent anode plate forms current path, and the flue gas of the electric field passage of flowing through enters filter bag row through current path; The outside of each filter bag adjacent with the electric field passage is equipped with a positive plate; And the width of positive plate is more than or equal to the diameter of filter bag, so that positive plate separates the discharge electrode of filter bag and electric field passage.This electric-bag complex dust collector has not only significantly improved the chargeability of dust, has improved efficiency of dust collection, and has effectively avoided filter bag directly adjacent with discharge electrode, thereby has effectively prolonged the service life of filter bag, has reduced the dedusting cost.But the smoke distribution of this electric-bag complex dust collector is very unreasonable, and most of flue gas directly enters electricity bag dedusting area, filter bag is consisted of wash away, and has affected the service life of filter bag, and the flue gas of skewness, has affected the efficiency of dust collection of deduster yet.
Summary of the invention
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of rational in infrastructure, smoke distribution is even, life of bag filter is long, operating cost is low and efficiency of dust collection is high electric-bag complex dust collector.
The technical scheme that its technical problem that solves the utility model adopts is: comprise that inner chamber is provided with the casing of dirt pocket, be provided with electricity bag dedusting area in the dirt pocket;
Described electricity bag dedusting area comprises some roads electric field passage and is arranged at filter bag row between the electric field passage;
Described electric field passage comprises two row's anode rows and a discharging electrode wires row; Anode row is spliced by some positive plates, offers the smoke ventilator that several pass through for flue gas at positive plate; Two row's anode rows line direction parallel interval before the flue gas arranges; Discharge plume row is arranged equably along the front line direction of flue gas by some discharge plumes and forms, and discharge plume row be arranged between two anode rows, and parallel with anode row;
Described filter bag row is arranged by some filter bags line direction before the flue gas and forms, and filter bag row be arranged between the two electric field passages, and the electric field passage parallels;
The anode row front end of the rear end of two anode rows of each electric field passage and filter bag row both sides links to each other with arc spoiler B by arc spoiler A respectively; Arc spoiler B avoids flue gas directly to wash away filter bag, and arc spoiler A then stops flue gas directly to flow to the rear end from the front end of electric field passage, simultaneously, flue gas reasonably is distributed in the smoke ventilator on the positive plate flows to filter bag.
Further, described filter bag row is by behind the forward direction, and the spacing of filter bag progressively increases; This be because, when flue gas moves ahead in the electric field passage, although there is the flue gas of fraction to flow to filter bag by the smoke ventilator on the positive plate, but most of flue gas directly moves ahead in the electric field passage, be subjected to the effect of arc spoiler A to the rear end of electric field passage, smoke backflow and flow velocity are higher, so spacing makes the smoke distribution that flows to filter bag more even rationally by the filter bag arrangement that front and back progressively increase.
Further, described every row's filter bag row's below is provided with deflector row, and each deflector of deflector row raises after by forward direction successively along the front line direction of flue gas; Like this, the flue gas of avoiding on the one hand the filter bag below to move ahead directly flow to the rear end from the front end of dirt pocket, and the deflector that raises successively on the other hand makes flue gas upwards enter electricity bag dedusting area from the bottom of filter bag the flue gas even water conservancy diversion that makes progress.
Further, the front end of the described dirt pocket spoiler that is provided with suitable for reading, the lower end of upper spoiler is lower than the upper end, washes away filter bag to avoid flue gas to flow directly into the dirt pocket top.
Further, the front end end opening of described dirt pocket is provided with lower spoiler, and the upper end of lower spoiler is higher than the anode row lower end; The one, the lower end flue gas is imported in the electric field carry out dedusting, the 2nd, avoid flue gas that ash bucket is impacted and cause reentrainment of dust.
Further, the front end both sides of described dirt pocket are equipped with the side spoiler, outermost anode row front end close contact in the rear end of side spoiler and the electricity bag dedusting area, and the positive plate that consists of the anode row of the outermost both sides in the electricity bag dedusting area is the whole plate of not offering smoke ventilator, escapes between outermost sun plate row and dirt pocket inwall to avoid flue gas.
Further, the inner chamber of described casing is divided into two or more dirt pockets; Like this, can be according to the flue gas treating capacity, and be convenient to reasonable moulding, improve efficiency of dust collection.
The beneficial effects of the utility model are: it is rational in infrastructure, smoke distribution is even, has effectively prolonged the service life of filter bag, has reduced operating cost, has improved efficiency of dust collection.
