Specific embodiment
Desulfuration absorbing tower sprays CPR dust, and including three annular slabs being vertically arranged 1, the outer wall of annular slab 1 is arranged on de-
Sulfur absorbs on inner wall of tower, and below the spray equipment that annular slab 1 is located in desulfuration absorbing tower, annular slab 1 is first by several arcs 6
Tail is connected and forms, and is sloped downwardly in arc 6, and the angle [alpha] of inclination is less than or equal to 30 °.This three installations of structure setting
Annular slab 1 on desulfuration absorbing tower inwall, annular slab 1 is spliced in tower by several arcs 6, and assembling process need not move
Fire, installation process is simple, safety.Arc 6 is obliquely installed, and the angle that arc 6 is formed with horizontal plane is less than or equal to 30 °, makes
Arc 6 will not substantially increase the flow resistance of flue gas in tower, and can make to flow to the spray liquid in absorption tower inner rim region again
It is distributed and to middle section aggregative flow, can effectively eliminate gas bypass phenomenon in tower, improve the smoke desulfurization efficiency of system.
For making arc 6 fixing-stable, it is to avoid come off, desulfuration absorbing tower inwall circumferentially installs several connecting plates 2, adjacent
Arc 6 be arranged on connecting plate 2 by bolt 5.This structure can make arc 6 be fixed on desulfurization by connecting plate 2
Absorb on inner wall of tower, it is to avoid arc 6 comes off.
For making arc 6 fixing-stable, it is to avoid come off, desulfuration absorbing tower inwall circumferentially installs several vertical trianglees
Gusset 3, the bottom of annular slab 1 is connected with the hypotenuse of gusset 3.It is de- that this structure can make annular slab 1 be fixed on by gusset 3
Sulfur absorbs on inner wall of tower, it is to avoid annular slab 1 comes off.Simultaneously as annular slab 1 is obliquely installed, the bottom of annular slab 1 and gusset 3
Hypotenuse connect the contact area that can increase annular slab 1 and gusset 3, enable annular slab 1 fix stably, remain inclination
State.
For protecting connecting plate 2 excessively not washed away it is ensured that the service life of connecting plate 2, described arc 6 and connecting plate
Carbon steel anticorrosive coat 4 is set between 2.
Desulfuration absorbing tower inwall circumferentially installs several vertical hypotenuses triangle gusset 3 upwards, on the hypotenuse of gusset 3
Several connecting plates 2 are installed, the bottom of annular slab 1 is connected with gusset 3 by connecting plate 2.This structure makes annular slab 1 fixed stably
Gu, remain heeling condition, be difficult to rock.
For protecting connecting plate 2 and gusset 3 excessively not to be washed away it is ensured that the service life of connecting plate 2 and gusset 3, described
Between arc 6 and connecting plate 2, the lower end surface of connecting plate 2 and gusset 3 be respectively provided with carbon steel anticorrosive coat 4.
For making arc 6 fixing-stable, it is to avoid come off, desulfuration absorbing tower inwall circumferentially installs several connecting plates 2, connects
At least two screw rods 16 are arranged on plate 2, the fixed cover 7 opening up female thread is installed in cooperation on screw rod 16, and adjacent arc 6 passes through
