Spray Desulphurization Tower is the main equipment to absorb sulfur
dioxide (SO2), including single tower, twin towers, integrated
tower and so on. This kind of tower has advantages of high
desulphurization efficiency, little resistance, high adaptability
and availability. Spray desulphurization tower is dominated tower
among the gas desulphurization process.
Types of wet Scrubber Spray Tower
• Single Desulphurization Wet Scrubber
• Main-Vice Desulphurization Wet Scrubber
• Integrated Desulphurization Wet Scrubber
Main-vice Desulphurization Wet Scrubber
Main-vice 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.)
The gas after dedusting enters into the desulphurization tower, and
the SO2 containing in the flue gas is purified due to
neutralization reaction. The vice tower has the function of
dehydration in order to protect the ID fan, flue and chimney that
connected after the vice tower.
|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
Preparations before operation
1.Fill full the circulating sink, the limestone slurry pool and
soda slurry pool shall be filled adequate water, or high water
level will bring about corrosion of circulating water pump), Start
the limestone slurry pump and soda slurry pump to ensure the PH
value of clean water sink fall between 9 and 12. Control the water
level of sink to avoid water being extracted out completely.
2.Check whether the quality of joints between electric motor and
water pipe valve is acceptable and water supply system works.
3.Check whether electric motor of stirrer can operate normally and
storage of alkaline solution is enough.
4.Check whether sealing device of electric motor is good and shaft
is lubricative enough.
5.Check whether outlet baffle of induced fan is open.
6.Check whether outlet of wet scrubber spray desulphurization tower
7.Open the valves of spray devices.
