Single Desulphurization wet scrubber is made of carbon steel and
lined with granite. Several modules are separated and assembled at
site. (Or made as a whole steel-made tower and lined with granite.)
Inside devices include three-level spray systems, two-level baffle
demisters and three-level backwash spray equipments. The efficiency
to get rid of SO2 can be up to 90%.
Inside Details of Desulphurization Wet Scrubber
Eddy plate is used for uniforming gas distribution in the tower and
mixing gas-liquid fully, which greatly increases the
Installation of Wet Scrubber Spray Desulphurization Tower
Prepare scaffold before installation: If the equipment is less than
10t, light steel scaffold is suitable, if the equipment is more
than 10t, steel pipe scaffold is advised. Ordinary cement and sand
should be prepared well.Installation Materials
1.Acid-proof mortar (yellow) ,glassy water(transparent liquid),
furan powder(black), furan resin (black liquid), the above
installation accessories will all be delivered from my company
together with equipment.
2.Acid-proof cement: 25kg/bag, equipped with 1kg curing agent,
mixing evenly after opening.
|1||After ensuring the position of desulfurization spray tower,
infrastructure should be covered normal mortar, the horizontal
position should be found after installing the first section
according to the number of each section.|
|2||Please ensure the consistency between inlet center of the device
and the boiler outlet duct center. The connection should be smooth
to reduce the resistance of the system.|
|3||When hoisting one section, rub the furan resin daub dispatched
together with the equipment and then apply furan powder as well as
furan resin daub at a ratio of 2.5:1. Then stir and pave them
evenly on the annular face of the shell, about 1 to 2 cm thick.
When stirring the daub, we shall control the time.|
|4||After acid-proof mortar is used to connect sections, joint should
be filled with furan resin daub.|
|5||Spray pipe, mist eliminator, back washing pipe should have been
installed. If somewhere need to be welded, please pay attention to
falling sparks to light up mist eliminator.|
|6||After the completion of hoisting the whole equipment, daub shall be
used to fill full the notch of each section connection and build a
slope that is inclined in a downward way so that the rain dew will
not accumulate at the seams of the equipment under outdoor
Points for Attention
1.Tower should operate under the water state in case of affecting
its service life.
2.When designing mist eliminator system, the effect of flying ash
concentration in the inlet of FGD device should be taken into
consideration. The system should also include water flushing and
drainage system which can clean up sediments in the mist
eliminator. The sediments can be cleaned up automatically or by
man. Flushing water is process water.
3.Water quality of desulfurization liquid should be promised.
Filter must be installed in main circulation pump to prevent
impurity particle and massive slurry from entering into spray
system and avoid pipe wear and nozzle clogging.
4.According to technological requirements of desulfurization, PH
value of liquid should be controlled efficiently in case that basic
supersaturation of liquid causes crystallization. If superacidity
will reduce the efficiency of desulfurization and affect service
life of corrosion-resistant materials.
5.For the normal combustion of furnace and the normal operation of
desulfurization dust collector, operators need to strictly
implement the following steps:
Spray desulfurization equipment will be used for desulfurization
process in this system.
