The side-entry absorption tower agitator located in the slurry tank in the absorption tower is an important component to maintain the normal operation of the wet flue gas desulfurization system. It is used to stir the slurry in the absorption tower to prevent precipitation, and can also promote the uniformity of oxidized air. Chemicalization is conducive to the progress of reactions in the slurry, but it is also subject to a variety of corrosion effects. In order to reduce the adverse effects of corrosion on the service life of the blade, it is necessary to select suitable materials and shapes to prepare the blade. Compared with single austenitic alloys with the same alloy composition, dual-phase (ferrite + austenite) alloys have similar corrosion resistance, but have better mechanical properties, which makes dual-phase alloys more resistant to wear and stress. It has better corrosion and cracking ability, so dual-phase alloy has become an important material for the preparation of absorption tower stirrer blades. Corrosion resistance is an important factor affecting material selection. The higher the content of chromium, molybdenum and nitrogen, the better the corrosion resistance. Therefore, most corrosion-resistant alloys have a high content of chromium, molybdenum and nitrogen to improve the use of propellers. life.
The shape of the blade also affects the corrosion status, stress distribution and stirring effect of the blade. The diameter of the blade is an important part of the blade design. The increase in the diameter of the blade will significantly enhance the turbulence intensity and improve the mixing effect. However, the increase in the weight of the blade will decrease the mixing efficiency. The increase in the speed of the tail section of the blade will cause the edge of the blade to The abrasion is more obvious. Usually the blades have a downward curved surface to produce an efficient downward suction effect, allowing the fluid medium to move smoothly. The stirring effect can also be further optimized by changing the inclination angle along the length direction and the chord width of the curved surface. The determination of the blade shape can be obtained through simulation calculations using computer software.
