Description
Technical field
The present invention relates to a kind of cleaner technical field for smoke gas treatment, relate to specifically a kind of efficient uniform flow type bag-type dust collector.
Background technology
Existing a kind of sack cleaner, contains housing, dust filtration device and pulse ash remover, and dust filtration device comprises cloth bag and cage, and cloth bag is arranged on cage, and cage upper end is arranged on the card being provided with in housing, and pulse ash remover is positioned at the top of card.Cloth bag is straight tube structure, suitable for reading equal to lower port diameter.In the time that air-flow enters cloth bag inner chamber from cloth bag surrounding through cloth bag layer, ascending air amount constantly increases, and area of section is constant all the time, air velocity is very large along gradient on cloth bag length direction, air-flow is extremely inhomogeneous, causes local resistance to increase, thereby affects efficiency of dust collection.Secondly, in the time that cloth bag is carried out to pulse jet, winding-up throughput constantly reduces from top to bottom, and the area of section of cloth bag is constant, and winding-up dynamics is more downwards less, causes top winding-up dynamics excessive, and bottom winding-up amount is inadequate; These two kinds of phenomenons have directly caused the generation of pulse valve frequent operation phenomenon, have affected the service life of pulse valve.Meanwhile, the design of above-mentioned cloth bag mounting structure is all that cloth bag one end in enclosure interior is fixed, and freely, therefore, as easy as rolling off a log generation is crooked for the other end, causes, between cloth bag, friction phenomenon occurs and causes cloth bag breakage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of efficient uniform flow type bag-type dust collector, and not only efficiency of dust collection is high for this efficient uniform flow type bag-type dust collector, and the long service life of pulse valve and cloth bag.
For solving the problems of the technologies described above, the efficient uniform flow type bag-type dust collector of one of the present invention, contain housing, dust filtration device and pulse ash remover, dust filtration device comprises some cloth bags and cage, cloth bag is arranged on cage, cage upper end is arranged on the card being provided with in housing, pulse ash remover is positioned at the top of card, also contain positioning framework, this positioning framework is arranged in described housing and is positioned at the below of described cloth bag, this positioning framework is provided with locating hole, described cage is conical column structure, the shape of described cloth bag and the conical column structure of described cage match, the lower end of the conical column structure of described cage is connected with the upper end of alignment pin, the lower end of alignment pin is arranged in the locating hole that described positioning framework is provided with.
The back cut diameter of described cloth bag is 100mm to 300mm, and lower port diameter is 50 to 250mm.
Spacing in described some cloth bags between adjacent cloth bag can be 100mm to 400mm.
The lower end of the described cage conical column structure part that is connected with alignment pin upper end is provided with sealing gasket.
In above-mentioned efficient uniform flow type bag-type dust collector, in the time that dust-contained airflow enters cloth bag inner chamber from cloth bag surrounding through cloth bag layer, ascending air amount constantly increases, because cloth bag is pyramidal structure, area of section also continues to increase, air velocity is less along gradient on cloth bag length direction, and air-flow distributes comparatively even, thereby improves efficiency of dust collection; In the time that cloth bag is carried out to pulse dust cleaning, throughput from top to bottom constantly reduces, and the cross section of cloth bag also constantly reduces, effective compensation the throughput velocity attenuation that reduces to cause, thereby ensure that cloth bag all has good deashing impulsive force everywhere, thereby reduce the winding-up number of times of pulse valve, therefore extended the service life of pulse valve; Because the lower end of cloth bag arranges on positioning framework by alignment pin, thereby avoid cloth bag that crooked phenomenon occurs, therefore overcome between cloth bag the generation that friction occurs and cause disrepair phenomenon, extended the service life of cloth bag.

Detailed description of the invention
In Fig. 1, a kind of efficient uniform flow type bag-type dust collector, contains housing 1, dust filtration device 3 and pulse ash remover 5.Dust filtration device 3 comprises some cloth bags 6 and cage, and cloth bag 6 is arranged on cage 7, and cage 7 upper ends are arranged on the card 4 being provided with in housing 1, and pulse ash remover 5 is positioned at the top of card 4.Above-mentioned efficient uniform flow type bag-type dust collector also contains positioning framework 2, and this positioning framework 2 is arranged in described housing 1 and is positioned at the below of described cloth bag 6, and this positioning framework 2 is provided with locating hole 11.Described cage 7 is conical column structure, and the conical column structure of the shape of described cloth bag 6 and described cage 7 matches.The lower end of the conical column structure of described cage 7 is connected with the upper end of alignment pin 8, and the lower end of alignment pin 8 is arranged in the locating hole 11 that described positioning framework 2 is provided with.The back cut diameter of described cloth bag 6 can be 100mm to 300mm, and lower port diameter can be 50 to 250mm.Spacing in described some cloth bags 6 between adjacent cloth bag can be 100mm to 400mm.For preventing that cloth bag 6 lower ends and alignment pin 8 junctions, upper end from leaking out, leaking dirt, the cage 7 conical column structure lower ends part that is connected with alignment pin 8 upper ends is provided with sealing gasket 12.In above-mentioned efficient uniform flow type bag-type dust collector, in the time that dust-contained airflow enters cloth bag 6 inner chamber from cloth bag 6 surroundings through cloth bag layer, ascending air amount constantly increases, because cloth bag 6 is pyramidal structure, area of section also continues to increase, air velocity is less along gradient on cloth bag 6 length directions, and air-flow distributes comparatively even, thereby improves efficiency of dust collection.In the time that pulse ash remover 5 carries out pulse dust cleaning to cloth bag 6, throughput from top to bottom constantly reduces, and the cross section of cloth bag 6 also constantly reduces, effective compensation the throughput velocity attenuation that reduces to cause, thereby ensure that cloth bag 6 all has good deashing impulsive force everywhere, thereby reduce the winding-up number of times of pulse valve, therefore extended the service life of pulse valve.Because the lower end of cloth bag 6 arranges on positioning framework 2 by alignment pin 8, thereby avoid cloth bag 6 that crooked phenomenon occurs, therefore overcome between cloth bag 6 generation that friction occurs and cause disrepair phenomenon, extended the service life of cloth bag 6.
