Aluminum oxide roasting cooling equipment and modular aluminum oxide roasting cooling device

Abstract

The invention relates to aluminum oxide roasting cooling equipment and a modular aluminum oxide roasting cooling device. The modular aluminum oxide roasting cooling device comprises a connection pipeused for being connected with an aluminum oxide outlet of a cyclone cooling system, the connection pipe comprises a main pipeline and branch pipelines communicate with the main pipeline, the number ofthe branch pipelines is arranged two or above, the end, away from the main pipeline, of each branch pipeline is connected with one vertical cooler used for cooling aluminum oxide powder, and materialinlets of the coolers are provided with material inlet valves used for controlling opening and closing of the material inlets of the corresponding coolers. By means of the modular aluminum oxide roasting cooling device, an originally-used horizontal vulcanizing bed is replaced into the multiple identical coolers of smaller sizes, the problem of inconvenient of large equipment installation and replacement is solved, the size of spare equipment is also reduced, the spare cost is lowered, meanwhile, the maintenance space is increased, and convenience is provided for on-spot maintenance and inspection.

Description

technical field [0001] The invention relates to alumina roasting and cooling equipment and a modularized alumina roasting and cooling device. Background technique [0002] In the production process of alumina, the roasting process is one of the most energy-consuming and cost-intensive processes. The currently used roasters mainly include gaseous suspension roaster and circulating fluidized roaster. After the alumina is cooled by the cyclone cooling system from the roaster, the temperature is usually above 250°C and cannot be directly sent to the storage and transportation system. For the sake of equipment and To ensure the safety of personnel, the alumina cooled by the cyclone cooling system needs to be cooled again by the fluidized bed cooler. The fluidized bed coolers designed and used at home and abroad rely on increasing the cooling area to meet the requirements of process conditions. With the increase of the overall production capacity of the roaster, the area required...
