Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, described flue gas automatic equalization distributor, comprise the rotating shaft 2 being vertically installed on air intake flue 1 port of export flue gas shunting place, rotating shaft 2 is by runner assembly free axial rotation in air intake flue 1, the axle body of rotating shaft 2 is fixed with fume balanced distributor 3, the cross section of fume balanced distributor 3 is arranged in the quadrangle surrounded by the windward side of two symmetrical distributions and the lee face of two symmetrical distributions, angle angular range a between two windward sides is 20 ~ 60 °, angle angular range b between two lee faces is 110 ~ 130 °, in the present embodiment, angle angle a between two windward sides is 50 °, angle angle b between two lee faces is 117 °, the sensitivity of the flue gas automatic equalization distributor that this angle is arranged is high, in the present embodiment, the structure of described runner assembly is: in the upside flue inner wall at port of export flue gas shunting place, be provided with the first locating sleeve 4, downside flue outer wall is provided with bearing 5 and bearing block 6, the lower end movable sealing of rotating shaft 2 is through inserting in bearing 5 after air intake flue 1, the upper end of rotating shaft 2 is provided with groove 7, groove 7 and the first locating sleeve 4 are formed installs chamber, spring 8 and ball 9 is disposed with from bottom to top in installation chamber, ball 9 upwards withstands on gently all the time in flue inner wall under the elastic force effect of spring 8, and when ball 9 is upwards withstood in flue inner wall by spring 8, the top of ball 9 is just in time positioned at the first locating sleeve 4, bottom is just in time arranged in groove 7, above-mentioned runner assembly structure is simple, installation and maintenance are convenient, and because point cantact is carried out by ball 9 and the flue inner wall of air intake flue 1 in the upper end of rotating shaft 2, thus farthest reduce the resistance be subject to when rotating shaft 2 rotates, ensure that flue gas automatic equalization distributor has higher sensitivity all the time, in the present embodiment, the upside flue inner wall of air intake flue 1 is also provided with the second locating sleeve 10 simultaneously entangling the first locating sleeve 4 and rotating shaft 2 upper end, ball 9 can be effectively avoided to depart from from installation chamber like this, prevent rotating shaft 2 from shaking because ball 9 departs from from installation chamber, improve the operation stability of rotating shaft,
Operation principle of the present invention is as follows:
The flue gas entering air intake flue 1 is diverted to each bin again after the fume balanced distributor 3 of the flue gas automatic equalization distributor at gas distribution place, when being greater than the flue gas flow by right side by the flue gas flow on the left of fume balanced distributor 3, the active force that the windward side, left side of fume balanced distributor 3 is subject to can be greater than the active force that windward side, right side is subject to, fume balanced distributor 3 will 2 rotate clockwise around the shaft, thus reduce the air intake bore of the air outlet on the left of fume balanced distributor 3, and increase the air intake bore of the air outlet on the right side of fume balanced distributor 3 simultaneously, when being less than the flue gas flow by right side by the flue gas flow on the left of fume balanced distributor 3, the active force that the windward side, left side of fume balanced distributor 3 is subject to can be less than the active force that windward side, right side is subject to, fume balanced distributor 3 will 2 rotate counterclockwise around the shaft, thus reduces the air intake bore of the air outlet on the right side of fume balanced distributor 3 and increase the air intake bore of the air outlet on the left of fume balanced distributor 3 simultaneously, constantly swung by fume balanced distributor 3 following left both sides flue gas flow difference, thus make flue gas energy equilibrium assignment in each row bin.Advantage of the present invention is: the fume balanced in air intake flue can be assigned in each row bin, make the flue gas flow load balancing of each bin, improve dustfall efficiency, extend the service life of filter bag.
