farthest reduce the resistance be subject to when the first rotating shaft 21 rotates, further ensure the sensitivity of flue gas automatic equalization distributor, in the present embodiment, the upside flue inner wall of air intake breaching 16 is also provided with the second locating sleeve simultaneously entangling the first locating sleeve 23 and rotating shaft 21 upper end, ball 28 effectively can be avoided like this to depart from from installation chamber, improve operation stability,
Operation principle of the present invention is as follows:
The flue gas entering air intake breaching 16 first can be diverted to left air intake flue arm 14 again with right air intake flue arm 15 after the fume balanced distributor at its gas distribution place, when the flue gas flow by entering left air intake flue arm 14 on the left of fume balanced distributor body 22 is greater than the flue gas flow by entering right air intake flue arm 15 on the right side of it, the active force that the windward side, left side of fume balanced distributor body 22 is subject to can be greater than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate clockwise around the shaft, thus reduce the air intake bore of the gas approach of left air intake flue arm 14, and increase the air intake bore of the gas approach of right air intake flue arm 15 simultaneously, when the flue gas flow by entering left air intake flue arm 14 on the left of fume balanced distributor body 22 is less than the flue gas flow by entering right air intake flue arm 15 on the right side of it, the active force that the windward side, left side of fume balanced distributor body 22 is subject to can be less than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate counterclockwise around the shaft, thus reduce the air intake bore of the gas approach of right air intake flue arm 14, and increase the air intake bore of the gas approach of left air intake flue arm 15 simultaneously, so just effectively can ensure that fume balanced is assigned to left air intake flue arm 14 with right air intake flue arm 15,
The flue gas entering left air intake flue arm 14 is diverted in the first left bin 4 and the first right bin 5 through the fume balanced distributor at its gas distribution place more again, when the flue gas flow by entering the first left bin 4 on the left of fume balanced distributor body is greater than the flue gas flow by entering the first right bin 5 on the right side of it, the active force that the windward side, left side of fume balanced distributor body is subject to can be greater than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate clockwise around the shaft, thus reduce the air intake bore of the air inlet of the first left bin 4, and increase the air intake bore of the air inlet of the first right bin 5 simultaneously, when the flue gas flow by entering the first left bin 4 on the left of fume balanced distributor body is less than the flue gas flow by entering the first right bin 5 on the right side of it, the active force that the windward side, left side of fume balanced distributor body is subject to can be less than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate counterclockwise around the shaft, thus reduce the air intake bore of the air inlet of the first right bin 5 and increase the air intake bore of air inlet of the first left bin 4 simultaneously, so just can ensure that fume balanced is assigned in the first left bin 4 and the first right bin 5,
And the flue gas entering right air intake flue arm 15 is diverted in the second left bin 7 and the second right bin 8 through the fume balanced distributor at its gas distribution place more again, when the flue gas flow by entering the second left bin 7 on the left of fume balanced distributor body is greater than the flue gas flow by entering the second right bin 8 on the right side of it, the active force that the windward side, left side of fume balanced distributor body is subject to can be greater than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate clockwise around the shaft, thus reduce the air intake bore of the air inlet of the second left bin 7, and increase the air intake bore of the air inlet of the second right bin 8 simultaneously, when the flue gas flow by entering the second left bin 7 on the left of fume balanced distributor body is less than the flue gas flow by entering the second right bin 8 on the right side of it, the active force that the windward side, left side of fume balanced distributor body is subject to can be less than the active force that windward side, right side is subject to, fume balanced distributor body 22 will 21 rotate counterclockwise around the shaft, thus reduce the air intake bore of the air inlet of the second right bin 8 and increase the air intake bore of air inlet of the second left bin 7 simultaneously, so just can ensure that fume balanced is assigned in the second left bin 7 and the second right bin 8,
In sack cleaner running, when the Resistance Value of certain bin reaches design resistance value and needs to carry out off-line ash-clearing, first close the outlet damper door 19 on the air-out flue arm 18 corresponding to this bin, now, this needs the bin of deashing can be in the immobilising space of air-flow, there is no the effect of negative-pressure adsorption power, then the pulse jetting deashing mechanism 13 in the upper air-purifying chamber 10 of this bin is started, after the dust being attached to filter bag 12 surface departs from filter bag 12 surface under the effect of pulse jetting deashing mechanism 13, by there is no the effect of negative-pressure adsorption power, thus " skylight " effect can not be there is, dust only can under sufficient gravitational settling sorting, the overwhelming majority directly falls into the ash bucket of below, only have the fine and ultra tiny dust of small part can continue to be suspended in lower smoke chamber 11, after pulse jetting deashing mechanism 13 completes jetting deashing, open the outlet damper door 19 on the air-out flue arm 18 corresponding to this bin after first waiting for a period of time again, make this bin proceed dedusting work, in the moment of opening corresponding outlet damper door 19, after sufficient gravitational settling sorting, continue the fine and ultra tiny dust of small part be suspended in lower smoke chamber 11 can by the surface of negative-pressure adsorption in filter bag 12, form the new long-pending rack-layer as dedusting medium, further increase the efficiency of dust collection of filter bag 12.
Advantage of the present invention is: (1) can use off-line ash-clearing mode to carry out jetting deashing to filter bag, namely when a certain bin needs deashing, close the outlet damper door of the air-out flue arm communicated with the air outlet of the upper air-purifying chamber of this bin, and then unbalanced pulse jetting deashing mechanism carries out jetting deashing to filter bag, because now bin is the immobilising Static-state Space of air-flow, therefore, after the dust on filter bag departs from filter bag surface under the high pressure gas effect that pulse jetting deashing mechanism sprays, only has gravitational settling assorting room, and be not subject to any negative-pressure sucking effect, therefore, " skylight " effect that dust passes through from the micropore of expansion can not be there is, and then substantially increase dustfall efficiency, extend the service life of filter bag, (2) the flue gas flow load balancing of each bin can be remained, further increase dustfall efficiency, extend the service life of filter bag.
