Refering to fig. 1, Fig. 2 is the embodiment of the utility model wet desulfuration tower, wet desulfuration tower, including 1 He of support girder
Spray supervisor 2, the support girder 1 two are one group, and support secondary beam 3, the spray are equipped between two support girders 1
Supervisor 2 is arranged in parallel with support girder 1, and the spray supervisor 2 is equipped with slurries spray port 4, and the spray supervisor 2 passes through pipe collar
5 are fixed on the lower section of support secondary beam 3, and the pipe collar 5 is bolted on support secondary beam at U-shaped, the both ends of the pipe collar 5
On, in order to increase intensity, every end can be fixed by two groups of bolts.
The setting support secondary beam 3 between support girder 1, by supporting secondary beam 3 that can both consolidate to two support girders 1
Surely guarantee its stability, and setting spray supervisor 2 can spray slurries below support secondary beam 3, to prevent flue gas from branch
It supports and escapes at girder 1, recycle pipe collar 5 that spray supervisor 2 is suspended on 3 lower section of support secondary beam, guarantee that spray supervisor 2 is steady in a long-term
Operation, and the slurries sprayed will not be washed into support girder 1 and secondary beam, improve the uniformly distributed property of flue gas flow field, improve desulfurization effect
Rate extends the service life of spraying layer, improves the safe operation reliability of desulphurization system.
Further, it is possible to be equipped with the spray looped pipeline 6 vertical with support girder 1 on spray supervisor 2, the spray is secondary
It also is provided with slurries spray port 4 on pipe 6, to expand spray coverage area, prevents flue gas from escaping.
It since spray 6 weight of looped pipeline is also heavier, and sprays looped pipeline 6 and is only fixed with spray supervisor 2, in order to guarantee to spray looped pipeline
6 stability, spray looped pipeline 6 are fixed on spray supervisor 2 by mounting shell 7, and the mounting shell 7 includes 71 He of the first mounting portion
Second mounting portion 72, first mounting portion 71 is arc-shaped, and arc-shaped corresponding central angle is less than 180 degree, first peace
Dress portion 71 is fixed on spray 2 outer circle walls of supervisor, increases the contact area between spray supervisor 2, second mounting portion
72 be hollow cylinder, and the inner hole of second mounting portion 72 is equal with the spray outer diameter of looped pipeline 6, is opened on first mounting portion 71

Dress shell 7 increases and sprays the connection between supervisor 2 and spray looped pipeline 6, provides enough strength supports, ensure that spray is secondary
The stabilization of 6 position of pipe.
Spray looped pipeline 6 can also be arranged in pairs, and be distributed about spray 2 axisymmetricals of supervisor, and every institute simultaneously
Stating the slurries spray port 4 on spray looped pipeline 6, the underface of support girder 1 is arranged at least one, is not easy to form dead angle, allows spray
Drench the covering of slurries gamut.
In view of slurries spray supervisor 2 in more flow it is smaller, in order to keep spray supervisor 2 in each position pressure one
It causes, the spray supervisor 2 gradually becomes smaller along sprayed slurry flow direction caliber, which, which becomes smaller, can be the change of duration caliber
It is small, it is also possible to become smaller every one section of caliber.
Pipe collar 5 generally uses cross section for L shape, can both increase the contact surface between pipe collar 5 and spray supervisor 2 in this way
Product can also increase pipe collar 5 and support the contact area between secondary beam 3, facilitate being fixedly connected for pipe collar 5, and adjacent pipe collar 5
Between spacing control at 1.6~2.0 meters, the too long weight for being not easy to bear spray supervisor 2 more demanding to pipe collar 5 of spacing, and
Spacing is too short, to arrange pipe collar 5 more, will cause waste.
In addition the spray angle general control of blade spray port forms best spray angles, angle between 80~120 degree
It is too small to spend small covering surface, it is excessively sparse that the excessive sprayed slurry of angle forms droplet.
The technical solution for increasing the present apparatus under the support girder 1 in normal wet desulfuration tower, to 1 lower section of support girder
Region carry out slurries covering, thus avoid flue gas from the region escape, ensure that the efficiency of gas cleaning, make discharge can reach
Mark.
