The working environment of the desulfurization absorption tower mixer in thermal power plants is very harsh. The coal-fired flue gas that needs to be desulfurized will generate an acidic mixture during the cycle absorption process, and gradually enrich it as the cycle time is extended, resulting in a combination of chemical corrosion, electrochemical corrosion, crystallization corrosion and abrasion corrosion on the metal surface of the agitator impeller. corrosion. This requires the absorption tower mixer impeller to have high mechanical properties, good chemical stability and thermal stability, and excellent impermeability properties. At the same time, low cost, low construction difficulty, easy repair, and safety must also be considered. Long running time characteristics. To improve the corrosion resistance and wear resistance of the absorption tower agitator impeller, we can start from two aspects: material and blade design. The service life can be improved by using corrosion-resistant and wear-resistant alloys, such as composite steel plates composed of stainless steel, carbon steel and high-alloy steel, and nickel-based high-temperature alloys designed to have fewer solid particles impacting the blade surface, even force distribution and good stirring effect A good blade shape can also increase the service life of the impeller.
In addition, surface treatment (ion implantation, laser heat treatment, etc.) can also be used to form a strengthening layer on the surface of the impeller, which can greatly improve the corrosion and wear resistance of the alloy, extend the life and save costs, such as for gas corrosion resistance. The designed melt-spraying layer has a service life that is % longer than that of traditional agitator impellers.
Guangdong Essen Environmental Protection Technology Co., Ltd. has fully studied the impact of materials and shapes on the life of the propeller. By adding a baffle at the front end of the propeller, it blocks the direct impact of solid particles on the back of the impeller, greatly reducing impact wear. , using streamlined design, less wear on the blades under the same thrust, these blade designs can increase service life. The blades and rotating shaft are made of high- and high-content dual-phase alloys, which have good corrosion resistance and wear resistance.
Guangdong Essen Environmental Protection Technology Co., Ltd. is a high-tech environmental protection company integrating R&D, production and sales. The company is located in Guangzhou, a city at the forefront of China's reform and opening up. It is mainly committed to manufacturing desulfurization mixers for environmental protection facilities of large domestic and foreign enterprises. The company has professional technical personnel with rich design and practical experience, and cooperates with a number of high-tech professional units including South China University of Technology to ensure that it provides technology and products that meet customer needs.
