First, look at
the limestone - gypsum wet flue gas desulfurization process.
one above is the desulfurizer tower
It does a lot
processes release a lot of SO2, which is absorbed in the
So you don't
have to worry about SO2 emissions
desulfurization tower is covered with calcium sulfate and calcium carbonate, its
tray and nozzle went out of action
The function of scale inhibitor is
1. Increase the solubility of scaling compounds
acids and polyelectrolytes in the scale inhibitor disassociate in water, and
form negatively charged molecular chains. The molecular chain and Ca2+
form stable complex, thereby increasing the solubility of CaSO4
2. Lattice distortion theory
crystallization is strictly in accordance with the order.
acids in the scale inhibitor will chelate with Ca2+
, inhibiting the
sequential growth of the lattice, making the lattice distorted and difficult to
organic acid surface active agent molecules are involved in lattice growth,
lattice dislocation, the formation of some holes, making the scale soft.
3. Electrostatic repulsion
have strong adsorbability after ionizing in water. They will adsorb CaSO4
small crystal, dust, sediment, etc., and change the charge distribution on the
particle surface to form a double electric layer, thus preventing the collision
small crystal to form a large crystal, and preventing the
collision with the metal heat transfer surface to form a scale layer.
is an excellent scale inhibitor and can be use in desulfurization tower system
to prevent fouling.
