The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Novel electric bag complex dust collector air-flow distributed combination device as shown in Figures 1 to 3, comprise housing, electric precipitation district 10 and bag-type dust district 20 are set in housing, also comprise airflow-distribution board 110 and board 120, electric precipitation district 10 comprises entrance point and outlet side, outlet side is arranged between electric precipitation district 10 and bag-type dust district 20, airflow-distribution board 110 is arranged on entrance point, be provided with opening area on airflow-distribution board 110, opening area is divided into the first opening area 111 from top to bottom, the second opening area 112 and the 3rd opening area 113, the first opening area 111, the percent opening of the second opening area 112 and the 3rd opening area 113 and the from top to bottom minimizing successively of perforate aperture.
The perforate aperture of the first opening area 111 is 120mm-180mm, and percent opening is 40%-50%; The perforate aperture of the second opening area 112 is 80mm-120mm, and percent opening is 30%-40%, and the perforate aperture of the 3rd opening area 113 is 40mm-80mm, and percent opening is 20%-25%.The area ratio of the first opening area 111, the second opening area 112 and the 3rd opening area 113 is about 2: 2: 1.The lower end of airflow-distribution board 10 arranges dust leakage port 114, and dust leakage port 114 is elongated slit, and its width is 20mm-40mm, and leakage dirt is set, and 114, so that the dust of air-flow demarcation strip 10 lower ends enters ash bucket 40.
Novel electric bag complex dust collector air-flow distributed combination device also comprises air inlet buffering dedusting area 30, entrance point is arranged between air inlet buffering dedusting area 30 and electric precipitation district 10, the interior buffer board that arranges of air inlet buffering dedusting area 30, buffer board can be netted or other forms, comprise the first buffer board and the second buffer board, a plurality of buffer boards can also be set.Novel electric bag complex dust collector air-flow distributed combination device also comprises outlet smoke box 50, and outlet smoke box 50 is arranged in bag-type dust district 20.
After the air-flow that carries dust entered from air inlet buffering dedusting area 30, after the first buffer board, the second buffer board, air velocity got buffering to a certain extent.When arriving airflow-distribution board 110, opening area due to distributing on airflow-distribution board 110 different percent openings, different pore size, therefore being divided into three floor, air-flow enters electric precipitation district 10, because the air-flow velocity on top is very fast, at first air-flow arrives board 120, and perforate aperture and the percent opening of the first aperture portion 121 of board 120 are less, under the effect of pressure, the lower end of air flow direction board 120 enters bag-type dust district 20 through the second aperture portion 122.In the electric precipitation district 10, dust granule is subjected to the electric field force effect, and the particle that particle diameter is larger is adsorbed by positive plate and is deposited to ash bucket 40, and efficiency of dust collection reaches 70%～80%; Remaining subparticle (0.5 μ m～2 μ m) enters bag-type dust district 20, and under the interception function of the fiber filtering of filter bag 210, subparticle is blocked and gets off to be deposited to ash bucket 40, the total efficiency of dust collection of the flue gas through filter bag 210 after be 99.96% reach more than.This Novel electric bag complex dust collector air-flow distributed combination device can be avoided the generation of electric precipitation district 10 eddy current effectively, reduce the reentrainment of dust phenomenon, increased simultaneously flue gas in the electric precipitation district time of staying of 10, improve efficiency of dust collection; Flue gas can form a uniform air flow in 20 bottoms, bag-type dust district after board 120, the excessive filter bag that causes 210 breakages of filter bag 210 local pressures have been avoided, effectively reduce air-flow for directly the washing away of filter bag 210 sides, extend 210 service lifes of filter bag.
The below describes advantage or the principle of the embodiment of the present invention.
10 entrance point and outlet side arrange respectively airflow-distribution board 110 and board 120 to embodiment of the present invention Novel electric bag complex dust collector air-flow distributed combination device in the electric precipitation district, when making air-flow through airflow-distribution board 110, because the top-down percent opening of airflow-distribution board 110 is different, air-flow is being divided into the air-flow of three layers of different in flow rate when slowing down, make its holdup time that is increased in electric precipitation district 10, improve the efficiency of dust collection in electric precipitation district 10.Simultaneously, when three layers of air-flow arrive board 120, because the percent opening of the aperture portion of board 120 is different, air-flow flows from top to bottom along board 120, can effectively suppress air-flow directly pours bag-type dust 20 pairs, district filter bag 210 and washes away, simultaneously steering current enters bag-type dust district 20 reposefully through the bottom of board 120, and reasonably air-flow distributes and can effectively improve the efficiency of dust collection in bag-type dust district 20.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
