HYDROGEN CHLORIDE &
SULFUR OXIDES REMOVAL SYSTEM
In this system, hydrated lime (calcium hydroxide) powder is injected into the exhaust gas through a dry venturi to neutralize acid gases. A baghouse (bag filter) is designed to allow a formation of a thick dust cake layer on its surface. when the exhaust gas passes through the baghouse, the unreached hydrated lime contained in the cake layer contacts and reacts with the acid gas in the exhaust gas, thereby improving the removal effect:
The chemical reaction
formulate are as follows:
2 HCl + Ca (OH)2
-------------- > Ca Cl2 + 2 H2O
So2 + Ca (OH)2
-------------- > CaSo3 + H2O
CaSo3 + 1/2 O2
-------------- > CaSo4
[CHARACTERISTICS]
The treatment allows for
removing 90 to 95% of hydrogen chloride and 55 to 88% of sulfur oxides.
[CAPACITY]
This system has no limit
on treated gas volume.
[FIELD OF APPLICATION]
This system can be
applied to any furnace exhaust gas, for example for Municipal Solid Waste [MSW]
incineration.
