Description

Technical Field

[0001] The invention relates to the technical field of spray granulation towers, and in particular to an energy-saving and environment-friendly spray granulation tower for processing alumina ceramic materials. Background Art

[0002] Alumina ceramics are a type of ceramic material with aluminum oxide as the main component. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Alumina ceramics are a widely used ceramic. Because of their superior performance, they have been widely used in many fields, such as electronics, machinery, chemical industry and other industries. In the processing of alumina ceramic materials, spray granulation is a key link.

[0003] Traditional spray granulation towers usually use high-power heating equipment to dry the atomized slurry during the drying process, which not only leads to a large amount of energy waste, but also increases production costs. Secondly, a large amount of waste gas is generated during the drying process. These waste gases are often accompanied by a large amount of heat. If they are discharged directly, it will not only pollute the environment, but also cause a large amount of heat to be wasted. In the current situation of global energy shortage, this runs counter to the environmental protection policy advocated by the country.

[0004] In addition, after the granulation is completed, the traditional spray granulation tower directly collects the spherical particles through the discharge port, and often cannot screen the spherical particles, which will cause these spherical particles to be uneven in size, reducing the quality and market competitiveness of the product.
