Description
Technical field
The utility model relates to a kind of large-scale sack cleaner, the deduster structure that particularly a kind of metallurgical gas Dry Adsorption purifies.
Background technology
At present in dry fume purifying system, need to add adsorbent to adsorb the harmful substance in flue gas, in gas-solid mixing process, adsorbent carries out adsorption cleaning to the nuisance in flue gas, but because the spacing between absorbent particles is far longer than particle diameter, mixing and absorption can only make the nuisance part in flue gas purify, in order to improve purification efficiency, realize the target of gas-solid " contact entirely " adsorption cleaning, dust on gas-cleaning duster filter bag (adsorbent) need to be uniformly distributed to (while guaranteeing that flue gas passes filter bag, nuisance touches adsorbent), and in existing Large Size Bag Type Filters, flue gas stream is all to enter into fillter section at the bottom of cleanner bag, in the time flowing change direction, there is on the one hand gas solid separation, part adsorbent was fallen into ash bucket before entering into fillter section, can not effectively contact with flue gas for more time, in addition on the one hand, because air-flow velocity between Action of Gravity Field and bag raises and reduces with filter bag height, cause dust concentration between bag to reduce with height, thereby the reduction that the dust thickness catching on filter bag is increased with filter bag height, bag flour dirt thickness is seriously inhomogeneous, filter bag upper end has better permeability, especially PM2.5 ultrafine dust is had to better permeability.This phenomenon, as long as air-flow enters fillter section at the bottom of filter bag of dust collector bag, then the distribution of good air-flow all can not solve.
If simply realize fillter section top air intake by the perforate of fillter section top, will cause flue gas directly to wash away filter bag, cause more serious Dust distribution inequality, reduce purification and the filter efficiency of existing equipment.
Summary of the invention
The purpose of this utility model is: a kind of large-scale sack cleaner is provided, substantially do not changing under the prerequisite of existing device manufacturing cost and investment, better realize the target of " with dirt filter dirt ", improve purification efficiency and the dust-filtering efficiency of dry purifying system, especially the filter efficiency of PM2.5 ultrafine dust, reduce the probability that occurs local high velocity air in dust collector ash hopper simultaneously, extended service life of equipment.
General principle of the present utility model is: cleaner fillter section is not only bottom air intake, and adopts top air intake simultaneously, and the dust carrying in flue gas can directly enter fillter section top, can make the upper and lower Dust distribution of filter bag more even.
According to above-mentioned principle and method, large-scale sack cleaner is carried out to structure of modification.The basic structure of existing large-scale sack cleaner comprises upper box, middle casing, ash bucket and filter bag, on middle casing, be provided with air inlet, upper box is provided with air outlet, ash bucket is provided with slag-drip opening, cycle stock charge door and overfall, in ash bucket, be provided with airflow-distribution board, upper box is provided with deashing control system.
The technical solution of the utility model is: a kind of large-scale sack cleaner, comprise middle casing and filter bag, and middle casing is provided with air inlet.In middle casing, air inlet one side is provided with air-flow reaction channel, and reaction channel is provided with the distinguished and admirable road of cloth near filter bag upside wallboard place.So deduster fillter section is realized upper and lower air intake simultaneously, the dust carrying in flue gas can directly enter fillter section top, make the upper and lower Dust distribution of filter bag more even, give full play to deduster filtration mechanism, realize the target with dirt filter dirt, improve purification efficiency and dust removal and filtration efficiency, the especially filter efficiency of PM2.5 ultrafine dust of cleaning system, reduced the discharge of pollutant.
In middle casing, air inlet side arranges air-flow reaction channel, and reaction channel arranges the distinguished and admirable road of cloth near filter bag upside wallboard place, and the distinguished and admirable road of cloth is gap-shaped short tube structure (having strip crevice on short tube), and is distributed in corresponding space between filter bag; Lower end, the distinguished and admirable road of cloth is higher than air inlet upside, and higher than air inlet free jet diffusion zone (calculate by the diffusion of air inlet free jet the region covering, if establish the distinguished and admirable road of cloth in this region, will form local high velocity air).This structure and distribute and can avoid local high speed dusty gas to purge filter bag improves the effective exercise distance of dust-contained airflow simultaneously, has avoided air inlet air-flow directly to purge filter bag and flow velocity is too high.After dusty gas enters deduster, part Dual-Phrase Distribution of Gas olid can enter the gap between filter bag by the distinguished and admirable road of cloth, dust can directly reach filter bag top, reduce the gas solid separation producing due to Action of Gravity Field, strengthen the distribution of filter bag top dust, promote that on whole device interior filter bag, Dust distribution is even, by uniform " entirely the contacting " of realizing pernicious gas and dust (adsorbent) of dust, better realize the target of " with dirt filter dirt ", improve purification efficiency and the dust-filtering efficiency of dry purifying system, especially the filter efficiency of PM2.5 ultrafine dust.Due to the shunting action of air-flow, reduce the probability that occurs local high velocity air in dust collector ash hopper simultaneously, extended service life of equipment.
Compared with the prior art, the utility model is by utilizing the method for setting up the distinguished and admirable road of cloth by filter bag upside wallboard at reaction channel, make the through deduster fillter section of dusty gas top, solve to a certain extent the problem of dust thickness vertical misadjustment (inequality) on the filter bag causing due to gas solid separation in deduster and gravitational settling, the purification efficiency and the especially filter efficiency of PM2.5 ultrafine dust of dust-filtering efficiency that under the prerequisite that substantially maintains original cost, have improved equipment, therefore the utility model has good promotional value and use value.

Detailed description of the invention
A kind of large-scale sack cleaner, as shown in Figure 1, Figure 2 and Figure 3, comprise upper box 3, middle casing 4, ash bucket 5 and the filter bag 6 of sack cleaner, on middle casing 4, be provided with air inlet 1, on upper box 3, be provided with air outlet 2, ash bucket 5 is provided with slag-drip opening 9, slag-drip opening 9 belows are ebullated bed 8, cycle stock charge door 10 and overfall 11, in ash bucket 5, be provided with airflow-distribution board 12, upper box 3 is provided with deashing control system 7, in middle casing 4, air inlet 1 one sides are provided with air-flow reaction channel 13, and reaction channel 13 is provided with the distinguished and admirable road 14 of cloth near filter bag 6 upside wallboard places.
In equipment running process, ash-laden gas enters reaction channel 13 from air inlet 1, is divided into two flow directions in reaction channel 13, and a part flows downward and enters dust collector ash hopper 5, under the effect of the interior airflow-distribution board 12 of ash bucket 5, becomes ascending air between bag; A part upwards flows in addition, under the effect in the distinguished and admirable road 14 of cloth, evenly enter the gap on fillter section top, in the process of filtering, dust is attached directly to filter bag 6 tops, dust on filter bag 6 is not only uniformly distributed in same level, and has reduced the distribution imbalance in vertical direction.
