Abstract
The invention discloses a filtering bag type deduster which comprises a dedusting box body, wherein one end of the dedusting box body is provided with an air inlet flange, and a filtering screen is arranged in the air inlet flange which comprises a fixed air inlet flange and a movable air inlet flange. The fixed air inlet flange is fixedly connected with the dedusting box body and externally connected with the movable air inlet flange through a fastener, the filtering screen is fixedly arranged between the fixed air inlet flange and the movable air inlet flange through a fastener, and four annular fastener arrays are provided. The filtering bag type deduster can perform one-step filtering on air containing dust, so that large particles and powder cannot enter the dedusting box body through the air inlet flange, direct impacting on the filtering bag is reduced, service life of a filtering bag is prolonged, unnecessary shutdown time of the filtering bag type deduster is reduced, and dedusting efficiency is improved.
Description
Technical field
The present invention relates to a kind of deduster, relate in particular to a kind of filter bag type deduster, belong to the device technique field that is used for filtering gas in the operation transportation.
Background technology
Deduster is the cleaner of from flue gas, separating dust; Deduster has a lot of kinds, and wherein the filter bag type deduster is more common a kind of in the deduster, is the deduster of being formed as filter element with filter bag; Have rational in infrastructure; Advantages such as efficiency of dust collection is high, and energy-saving effect is remarkable, the product in dust, airborne dust processing and the production process of industries such as building materials, light industry, metallurgy, chemical industry reclaims.The filter bag type deduster generally includes dust-removing box, air inlet flange, air outlet flange and filter bag; Air inlet flange, air outlet flange are separately positioned on the two ends of dust-removing box; Filter bag is arranged in the dust-removing box; Dusty gas gets in the dust-removing box from the air inlet flange, after filter bag filters, discharges from the air outlet flange.When dusty gas got into dust-removing box from the air inlet flange, because the throughput sudden enlargement, flow velocity reduced; Bigger particle in the dusty gas and dust can lower the impact to filter bag because collision and deadweight effect are separated, if contain bigger particle and dust more for a long time; The phenomenon that has little time to separate can occur, the impact of filter bag is caused direct impact, reduce the service life of filter bag; Need the frequent change filter bag; And extremely inconvenience of filter bag has caused filter bag type deduster unnecessary downtime, has reduced efficiency of dust collection.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind ofly can carry out coarse filtration to reduce the filter bag type deduster of the direct impact that filter bag is caused to dusty gas.
Technical solution of the present invention is achieved in that a kind of filter bag type deduster, comprises dust-removing box, and an end of said dust-removing box is provided with the air inlet flange, is provided with screen pack in the said air inlet flange.
Preferably, said air inlet flange comprises and decides air inlet flange and moving air inlet flange; Saidly decide the air inlet flange and be fixedly connected with dust-removing box; Saidly decide that the air inlet flange is outer to be connected with moving air port flange through securing member; Saidly decide to be provided with screen pack between air inlet flange and moving air inlet flange; Said screen pack is fixed on through securing member saidly to be decided between air inlet flange and moving air inlet flange.
Preferably, said securing member circular array is shown 4.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Filter bag type deduster of the present invention; Owing to be provided with screen pack in the air inlet flange, can once filter dusty gas, make bigger particle and dust not to get in the dust-removing box from the air inlet flange; Reduced the direct impact that filter bag is caused; Prolong the service life of filter bag, reduced filter bag type deduster unnecessary downtime, improved efficiency of dust collection.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of filter bag type deduster of the present invention;
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1;
Wherein: 1, dust-removing box; 2, decide the air inlet flange; 3, moving air inlet flange; 4, securing member; 5, screen pack.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Like accompanying drawing 1, the of the present invention a kind of filter bag type deduster shown in 2, comprise dust-removing box 1, an end of said dust-removing box 1 is provided with the air inlet flange; Said air inlet flange comprises decides air inlet flange 2 and moving air inlet flange 3; Saidly decide air inlet flange 2 and be fixedly connected with dust-removing box 1; Saidly decide that air inlet flange 2 is outer to be connected with moving air port flange 3 through securing member 4; Saidly decide air inlet flange 2 and 3 of moving air inlet flanges are provided with screen pack 5; Said screen pack 5 is fixed on through securing member 4 saidly decides between air inlet flange 2 and moving air inlet flange 3.Screen pack 5 can once filter dusty gas; Make bigger particle and dust not to get in the dust-removing box 1 from the air inlet flange, the dusty gas after once filtering is behind air inlet flange dust-removing box 1, and wherein remaining relatively large particle and dust can be owing to colliding and the deadweight effect is separated; Reduced the direct impact that filter bag is caused; Prolong the service life of filter bag, reduced filter bag type deduster unnecessary downtime, improved efficiency of dust collection; Simultaneously, when needing to change screen pack 5, screw off securing member 4; To move the air inlet flange and unload, change new screen pack 5 after, again with securing member 4 moving air inlet flange 3 with decide air inlet flange 2 and fix; Convenient and swift, reduced the replacing time, improved efficiency of dust collection once more.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
