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 the even distribution technique of flue gas stream in a kind of deduster, the even distribution technique of flue gas stream in particularly a kind of large-scale sack cleaner.
Technical background
Because the air-flow distribution mainly receives the influence of the airintake direction of equipment in the deduster; All to form high-speed eddy in the general deduster; Especially for large-scale sack cleaner; Flue gas stream forms a very big revolution whirlpool in deduster, in deduster, filter bag is formed strong souring, so air-flow evenly distributes to dedusting or the crucial influence of purification efficiency generation that improves system.There is not airflow distribution device mostly in the existing deduster; Even the equipment that has has added airflow uniform distribution device, but because not through experiment, it all can not produce a desired effect mostly; Thereby still exist medium-sized whirlpool in the equipment; Like this, filter bag lower end in the deduster is also formed impact to a certain degree, thereby reduced the purification efficiency or the efficiency of dust collection of deduster.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of this invention is to provide the even distribution technique of flue gas stream in a kind of large-scale sack cleaner.
The present invention through utilize air flow guiding, the gas shock whirlpool of separating, liquidate, four steps of rectification; Large-scale whirlpool in the deduster is separated; Make it become a plurality of medium-sized whirlpools; Utilize part air-flow and rotating eddy current to liquidate then, medium-sized eddy current is destroyed, and utilize deduster air-flow demarcation strip to carry out air-flow and integrate to the space between the filter bag bottom; Air-flow velocity in the deduster is reduced and evenly distribute, solved and exist large-scale or medium-sized whirlpool to make air-flow problem of uneven distribution in the deduster in the deduster.
Technical scheme of the present invention: the even distribution technique of flue gas stream in a kind of large-scale sack cleaner; The casing and the member thereof that comprise sack cleaner; There are charge air flow passage and filtration to use filter bag in the casing; It is characterized in that: the uprush demarcation strip is arranged, inclination gas-flow deflector, and the gas flow modulation mouth that liquidates on the uprush demarcation strip in the ash bucket of casing.The angle of inclination of inclination gas-flow deflector is 25 °～65 °, like this, can effectively the focused airflow that gets in the deduster evenly be led separately.
Preferably, described uprush demarcation strip two ends link to each other with the ash bucket of deduster casing, on the uprush demarcation strip, have the bar shaped gas flow modulation mouth that liquidates.Like this, can within the specific limits the flue gas that gets into deduster thoroughly be separated.
Preferably, described uprush demarcation strip top maintains one section air-flow rectification section between the filter bag of dust collector bottom, and this section space length is in the deduster between the air-flow demarcation strip 0.6～1.2 times of distance.
Compare with prior art; The present invention is through utilizing the gas-flow deflector water conservancy diversion, uprush demarcation strip separate gas stream, and utilizes the liquidate medium-sized whirlpool of gas shock, four steps of rectification, and the large-scale whirlpool in the deduster is separated; Make it become a plurality of medium-sized whirlpools; Utilize part air-flow and rotating eddy current to liquidate then, medium-sized eddy current is destroyed, and utilize deduster air-flow demarcation strip to carry out air-flow and integrate to the space between the filter bag bottom; Air-flow velocity in the deduster is reduced and evenly distribution; Solved and exist large-scale or medium-sized whirlpool to make air-flow problem of uneven distribution in the deduster in the deduster, improved the purification or the efficiency of dust collection of sack cleaner, also improved the service life of filter bag in the deduster simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation, but be not restriction protection scope of the present invention.
Embodiments of the invention:
As shown in Figure 1; The even distribution technique of flue gas stream in a kind of large-scale sack cleaner; The casing 1 and the member thereof that comprise sack cleaner have charge air flow passage 2 and filtration with filter bag 6 in the casing 1, uprush demarcation strip 3 is arranged in the ash bucket of casing 1; Inclination gas-flow deflector 4, and the gas flow modulation mouth 5 that liquidates on the uprush demarcation strip 3.Because inclination gas-flow deflector 4 is designed to certain angle of inclination (general angle of inclination is good with 25 °～65 °), like this, the even guiding of focused airflow that can will get in the deduster is separated.Uprush demarcation strip 3 two ends link to each other with the ash bucket of deduster casing 1, and the flue gas that will get into deduster within the specific limits thoroughly separates, and on uprush demarcation strip 3, have the bar shaped gas flow modulation mouth 5 that liquidates.Uprush demarcation strip 3 tops maintain one section air-flow rectification section between filter bag of dust collector 6 bottoms, and this section space length is in the deduster between the air-flow demarcation strip 0.6～1.2 times of distance.
The present invention is through utilizing the gas-flow deflector water conservancy diversion; Uprush demarcation strip separate gas stream, and utilize the liquidate medium-sized whirlpool of gas shock, four steps of rectification; Large-scale whirlpool in the deduster is separated, make it become a plurality of medium-sized whirlpools, utilize part air-flow and rotating eddy current to liquidate then; Medium-sized eddy current is destroyed; And utilize deduster air-flow demarcation strip to carry out air-flow to the space between the filter bag bottom and integrate, air-flow velocity in the deduster is reduced and evenly distribute, solved and exist large-scale or medium-sized whirlpool to make air-flow problem of uneven distribution in the deduster in the deduster; Improve the purification or the efficiency of dust collection of sack cleaner, also improved the service life of filter bag in the deduster simultaneously.
