The working medium in the absorption tower is limestone slurry or gypsum slurry and high content of chloride ions, which will cause serious corrosion and cavitation to the impeller during operation, which is detrimental to the service life of the mixer. The agitator blades convert the motor energy into slurry kinetic energy, and at the same time ensure that the blades have sufficient operating life, which requires improving the agitator to reduce blade abrasion. Improvements can be made from the following aspects. Impeller diameter
The most direct way to improve the blade is to increase the impeller diameter, which will increase the turbulence intensity of the slurry and improve the agitator effect. However, there are many factors that limit the enlargement of the impeller diameter, including the weight of the impeller and the tail section of the blade. speed and impeller efficiency. Usually due to space limitations in the absorption tower, multiple agitators with small impeller diameters are often used in the design.
Impeller speed
Increasing the blade speed can undoubtedly enhance the slurry mixed flow effect, but increasing the speed depends on the material strength of the impeller. High speed will cause excessive wear of the impeller. For high-density slurries in the absorption tower, low-speed impellers are usually used.
Impeller geometry
The geometry of the impeller includes the shape, size, angle and number of blades. Most mixers are of the three-blade type, which is also the most basic and practical type.
Impeller material
The blades have been immersed in the slurry of the absorption tower for a long time. The slurry is usually acidic and the temperature is relatively high. The value is maintained between . Choose corrosion-resistant and wear-resistant materials.
Guangdong Essen Environmental Protection Technology Co., Ltd. uses modern manufacturing technology to enhance the strength of the blades and improve the stability of the blades during work. It is very effective in preventing blades and petioles from breaking, and also reduces installation and maintenance work. quantity. The blade design adopts a streamlined design, which causes less wear on the blades under the same thrust, and is especially suitable for operation in long-term wear and corrosion environments. Choose high and high content duplex alloys to make the stirring shaft and impeller to improve corrosion and wear resistance.
