The reasonable working range of the absorption tower slurry is .~ It is acidic. There are solid particles and a large number of ions in the slurry, and the temperature is high. Therefore, the absorption tower mixer will cause wear and corrosion after working for a period of time. When the absorption tower mixer impeller works for a long time, the solid component is generally in the three-phase flow liquid medium of solid, liquid and gas of lime and gypsum with a concentration of about %. The maximum particle diameter of the medium solid of the slurry is about %, and the maximum content is up to %. When flowing through the impeller surface at a certain flow rate, it will be scoured on the impeller surface, causing surface wear, destroying the geometry of the impeller surface, reducing the service life of the impeller, reducing the working efficiency of the impeller, and thus affecting the performance of the absorption tower mixer. normal operation. The agitator impeller works in a three-phase flow medium environment of solid, liquid, and gas. The coal-fired flue gas that needs to be desulfurized will generate an acidic mixture during the circulation absorption process, and will gradually enrich as the circulation time increases, thereby interacting with the agitator impeller. Comprehensive corrosion occurs on metal surfaces.
The occurrence of corrosion and wear may cause desulfurization and loosening of the blades. This is because the torque is transmitted to the blades for a long time to overcome the resistance of the slurry and loosening occurs due to tightening fatigue, or because the bolt connection is soaked in turbulent slurry for a long time. Metal corrosion occurs and becomes loose. As the use time is further extended, the blades and petioles may break, endangering production safety. This is due to the frequent start and stop of the mixer or the corrosion, erosion and thinning of the metal in the slurry, which leads to a decrease in strength.
Guangdong Essen Environmental Protection Technology Co., Ltd. fully considered the working environment of the absorption tower mixer, and improved and developed a new type of absorption tower mixer on the basis of introducing, absorbing, and digesting the technology of similar products at home and abroad. . The blades and rotating shaft are made of wear-resistant and corrosion-resistant bidirectional alloy. The blade design adopts a streamlined design, which causes less wear on the blades under the same thrust. It is especially suitable for operation in long-term wear and corrosion environments. Guangdong Essen Environmental Protection Technology Co., Ltd. has professional technical personnel with rich design and practical experience, and cooperates with many high-tech professional units including South China University of Technology to ensure that it provides technologies and products that meet customer needs.
