In industrial flue gas desulfurization systems, although the nozzle is small, it bears a heavy responsibility – it directly determines the desulfurization efficiency and equipment operation stability. In the face of harsh working conditions such as high temperature, corrosion, and wear, material selection becomes crucial.Silicon carbide ceramics, with their inherent “hard power”, are becoming a favored solution in the field of desulfurization nozzles.
1、 Naturally corrosion-resistant ‘protective armor’
The acidic and alkaline media in the desulfurization environment are like “invisible blades”, and ordinary metal materials often cannot escape corrosion losses. The chemical inertness of silicon carbide ceramics endows it with strong corrosion resistance, and it can remain stable in strong acid environments, just like putting a layer of protective armor on a nozzle. This feature not only extends the lifespan of the nozzle, but also avoids the risk of desulfurization liquid leakage caused by corrosion.
2、 The ‘calm faction’ under high temperature
When the temperature inside the desulfurization tower continues to rise, many materials will soften and deform. However, silicon carbide ceramics can still maintain their original form at a high temperature of 1350 ℃, with a thermal expansion coefficient only 1/4 of that of metals. The high temperature stability allows the nozzle to cope with thermal shock with ease. This characteristic of ‘not panicking when exposed to heat’ ensures the continuous and stable operation of the desulfurization system.
3、 The ‘long-distance runner’ in the wear-resistant world
The high-speed flowing desulfurization slurry continuously washes the inner wall of the nozzle like sandpaper. The hardness of silicon carbide ceramics is second only to diamond, and its wear resistance is several times that of high chromium cast iron. This’ hard hitting ‘strength enables the nozzle to maintain precise spraying angle and atomization effect during long-term flushing, avoiding the decrease in desulfurization efficiency caused by wear and tear.
4、 The ‘invisible promoter’ of energy conservation and environmental protection
Thanks to the high density of the material itself, silicon carbide ceramic nozzles can achieve a more uniform atomization effect, improving the reaction efficiency between limestone slurry and flue gas. This “twice the result with half the effort” feature not only reduces the consumption of desulfurizers, but also reduces system energy consumption, providing substantial assistance for the green transformation of enterprises.
Under the promotion of the “dual carbon” goal, the reliability and long-term effectiveness of environmental protection equipment are increasingly valued. The silicon carbide ceramic desulfurization nozzle provides a “one labor, long escape” solution for industrial flue gas treatment through material innovation, with a longer service life and more stable working performance. This technological breakthrough of “winning with materials” is redefining the value standard of desulfurization systems – selecting suitable materials is itself an efficient investment.
As a company dedicated to the research and development of silicon carbide ceramics, we are committed to endowing environmental protection equipment with stronger “vitality” through material technology. Make the stable operation of each nozzle a reliable cornerstone in the battle to defend the blue sky.
