Abstract
The invention relates to a technology for uniformly distributing fume flow in a large bag-type dust collector. According to the technology, a box of the bag-type dust collector and members of the box are involved; an air flow inlet channel and a filter bag for filtering are arranged in the box; and perpendicular air flow partition plates, inclined air flow guide plates and opposite rushing air flow adjustment ports which are perpendicular to the air flow partition plates are arranged in an ash hopper in the box. The inclined air flow guide plates have a certain inclination angle, and concentrated air flow entering the dust collector is uniformly guided to be divided. Two ends of each perpendicular air flow partition plate are connected with the ash hopper of the box of the dust collector, fume entering the dust collector is completely divided in a certain range, and the bar-shaped opposite rushing air flow adjustment port is formed on each perpendicular air flow partition plate. An air flow rectification section is kept between the top of each perpendicular air flow partition plate and the bottom of the filter bag of the dust collector, and the space distance is 0.6 to 1.2 times the distance between the air flow partition plates in the dust collector.
Description
Technical field
The present invention relates to flue gas stream in a kind of deduster and be uniformly distributed technology, particularly in the large-scale sack cleaner of one, flue gas stream is uniformly distributed technology.
Background technology
Because air flow method in deduster is mainly by the impact of the airintake direction of equipment, all high-speed eddy will be formed in general deduster, especially for large-scale sack cleaner, flue gas stream forms a very large revolution whirlpool in deduster, in deduster, form strong souring to filter bag, therefore uniform stream distribution produces crucial impact to the dedusting or purification efficiency that improve system.Mostly airflow distribution device is not had in existing deduster, even if some equipment has added airflow uniform distribution device, but owing to not passing through experiment, it all can not produce a desired effect mostly, thus still there is medium-sized whirlpool in equipment, like this, impact to a certain degree be also form to filter bag lower end in deduster, thus reduce purification efficiency or the efficiency of dust collection of deduster.
Summary of the invention
In view of above-mentioned Problems existing, the object of this invention is to provide flue gas stream in a kind of large-scale sack cleaner and be uniformly distributed technology.
The present invention by utilizing air flow guiding, separate, the gas shock whirlpool that liquidates, rectification four steps, large-scale whirlpool in deduster is separated, it is made to become multiple medium-sized whirlpool, then fraction and pivotal eddy current is utilized to liquidate, by medium-sized vortex breaker, and the space between utilizing bottom deduster splitter plate to filter bag is to carry out air-flow integration, make the air-flow velocity in deduster reduce and be uniformly distributed, solve in deduster and there is the problem that large-scale or medium-sized whirlpool makes air flow method inequality in deduster.
Technical scheme of the present invention: in a kind of large-scale sack cleaner, flue gas stream is uniformly distributed technology, comprise casing and the component thereof of sack cleaner, charge air flow passage and filtration filter bag is had in casing, it is characterized in that: in the ash bucket of casing, have uprush demarcation strip, slanted gas flow guide plate, and the gas flow modulation mouth that liquidates on uprush demarcation strip.The angle of inclination of slanted gas flow guide plate is 25 ° ~ 65 °, like this, can effectively the focused airflow entered in deduster evenly be led separately.
Preferably, described uprush demarcation strip two ends are connected with the ash bucket of dust collector box body, uprush demarcation strip has bar shaped and to liquidate gas flow modulation mouth.Like this, can within the specific limits the flue gas entering deduster thoroughly be separated.
Preferably, maintain one section of air-flow rectification section between bottom described uprush demarcation strip top to filter bag of dust collector, this section of space length is 0.6 ~ 1.2 times of the spacing of splitter plate in deduster.
Compared with the prior art, the present invention is by utilizing gas-flow deflector water conservancy diversion, uprush divides air-flow, and utilize the medium-sized whirlpool of gas shock that liquidates, rectification four steps, large-scale whirlpool in deduster is separated, it is made to become multiple medium-sized whirlpool, then fraction and pivotal eddy current is utilized to liquidate, by medium-sized vortex breaker, and the space between utilizing bottom deduster splitter plate to filter bag is to carry out air-flow integration, the air-flow velocity in deduster is made to reduce and be uniformly distributed, solve in deduster and there is the problem that large-scale or medium-sized whirlpool makes air flow method inequality in deduster, improve purification or the efficiency of dust collection of sack cleaner, also improve the service life of filter bag in deduster simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation, but be not the restriction to protection scope of the present invention.
Embodiments of the invention:
As shown in Figure 1, in a kind of large-scale sack cleaner, flue gas stream is uniformly distributed technology, comprise casing 1 and the component thereof of sack cleaner, charge air flow passage 2 and filtration filter bag 6 is had in casing 1, uprush demarcation strip 3 is had in the ash bucket of casing 1, slanted gas flow guide plate 4, and the gas flow modulation mouth 5 that liquidates on uprush demarcation strip 3.Owing to slanted gas flow guide plate 4 to be designed to certain angle of inclination (general angle of inclination is good with 25 ° ~ 65 °), like this, the focused airflow entered in deduster evenly can be led separately.Uprush demarcation strip 3 two ends are connected with the ash bucket of dust collector box body 1, are thoroughly separated by the flue gas entering deduster within the specific limits, and on uprush demarcation strip 3, have bar shaped to liquidate gas flow modulation mouth 5.Maintain one section of air-flow rectification section between bottom uprush demarcation strip 3 top to filter bag of dust collector 6, this section of space length is 0.6 ~ 1.2 times of the spacing of splitter plate in deduster.
The present invention is by utilizing gas-flow deflector water conservancy diversion, uprush divides air-flow, and utilize the medium-sized whirlpool of gas shock that liquidates, rectification four steps, large-scale whirlpool in deduster is separated, it is made to become multiple medium-sized whirlpool, then fraction and pivotal eddy current is utilized to liquidate, by medium-sized vortex breaker, and the space between utilizing bottom deduster splitter plate to filter bag is to carry out air-flow integration, the air-flow velocity in deduster is made to reduce and be uniformly distributed, solve in deduster and there is the problem that large-scale or medium-sized whirlpool makes air flow method inequality in deduster, improve purification or the efficiency of dust collection of sack cleaner, also improve the service life of filter bag in deduster simultaneously.
