The special corrosion inhibitor is developed on the
basis of blast furnace gas flow rate, temperature, composition property, TRT
scaling position, scaling sample property and so on.
The special scale and corrosion inhibitor has the
characteristics of pertinence, high efficiency and economy, and can solve the
scaling and corrosion problems well, and inhibit the formation of ammonium
chloride crystalline salt in the unit. At the same time, the oxidation film is
formed on the blade to reduce the corrosion and scour of the acid gas and dust
in the coal chlorine, so as to achieve the best effect of alkali slow
corrosion.
Principle and characteristics of action:
After the agent is injected into the blast furnace
gas, the gasification and uniform mixing can be realized in an instant by means
of the gas temperature and kinetic energy.
Eutectic or adsorbed on the
surface of the crystal of inorganic salt in the reagent and gas, which distorts
the crystal lattice and destroys the crystalline behavior and orientation of
inorganic salt; in the gas, the switch and size of the crystal are changed to
avoid the formation of the three-dimensional network structure between the
crystals, to prevent the continuous formation and development of the crystal,
and to prevent the salt crystal (scale) in the gas from depositing in the
turbine blades, rotors, and other parts.
The surface active component in the medicament can clean the surface of the blade, eliminate the charge on the metal surface and prevent the impurity from attaching on the blade.
The medicament forms a layer of corrosion and scale
inhibition protective film on the surface of the blade, to prevent the salt
components and acid gas from contacting the blade surface and keep the metal
surface of the other parts of the blade device smooth
The medicament absorbs the acid gas in the gas, reduces the concentration of
the acid gas, achieves the inhibition effect, and prevents the occurrence of
the pitting corrosion.

Product descritption:
Performance: This product according to the characteristics of the TRT device, the development of a special corrosion inhibitor and scale inhibitor. It can reach the gasification state at high temperature in the blast furnace gas pipeline. The uniform mixture of gasification agent and flue gas can effectively restrain and shield the scaling in the TRT plant. And can form an oxide film on the surface of the blade to prevent corrosion of the best effect. This product has the function of forming film, cleaning and neutralizing acid.
Usage:
The dosing device is used
continuously. The dosing port of the gas pipeline is selected at a distance of
1.0 ~ 1.2 meters after the quick cutting valve of the feeding device, the
filling depends on the scaling of the TRT plant, and the general dosing
concentration is 60-100g/104m3h. If there is floating or dirty phenomenon, can
be used after shaking, does not affect the effect of use.
Packaging and storage and
transportation:
This product is packed in
25kg or 250kg plastic drum; store in a cool and dry place; valid for 12 months.
Handle with care to avoid impact.
