Abstract

The invention provides a waste heat recovery device for a high-temperature aluminum oxide roasting furnace, and belongs to the technical field of energy chemical waste heat recovery. The problems that waste heat of the roasting furnace shell is dissipated into the air environment, energy is wasted, and the operation environment of workers is deteriorated are solved. The high-temperature aluminum oxide roasting furnace comprises a shell heat conduction device, a circulation pipeline system and a heat user, the high-temperature aluminum oxide roasting furnace comprises a first roasting furnace body, the shell heat conduction device is arranged on the outer side of the lower cone position of the first roasting furnace body, and the two ends of the circulation pipeline system are communicated with the shell heat conduction device and the heat user respectively. The device is mainly used for utilizing waste heat of an outer shell of the roasting furnace to supply heat to residents near a factory, or heating gas of the roasting furnace to improve the combustion efficiency of the roasting furnace, and can also be used for providing domestic hot water for the factory.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical waste heat recovery, and in particular relates to a waste heat recovery device of a high-temperature alumina roasting furnace. Background technique [0002] At present, domestic aluminum hydroxide roasting furnaces are mainly suspended roasting furnaces. Natural gas and low calorific value coal gas are diffused and burned at a preheated air temperature of 600-750°C. The flue gas temperature after combustion is 950-1100°C. Remove the attached water and crystal water of aluminum hydroxide to produce alumina that meets the requirements of electrolysis and other uses. Due to the high-temperature roasting process, the local high-temperature area inside the combustion chamber is as high as 1700 ° C. The combustion heat insulation structure is heat-resisting refractory bricks and carbon steel plates from the inside to the outside. When the equipment is running, the external temperature of the...
