The utility model provides a gaseous suspension roaster with a fluidization retention device, belongs to the technical field of aluminum hydroxide roasting, and aims to solve the technical problem of high heat consumption in the aluminum hydroxide roasting process. The gaseous suspension roaster comprises a barrel, a feeding port and a gas outlet are formed in the upper portion of the barrel, a gas inlet is formed in the bottom of the barrel, a fluidization staying device is further arranged in the barrel and located above the gas inlet, and gas introduced from the gas inlet enters the barrel through the fluidization staying device. And a discharge hole is formed in the side wall of the cylinder body above the fluidization staying device. According to the utility model, the retention time of aluminum oxide in the roasting furnace is prolonged, and the roasting temperature of the roasting furnace is reduced, so that the heat consumption of the roasting furnace is reduced. 本实用新型提出了一种带流态化停留装置的气态悬浮焙烧炉，属于氢氧化铝焙烧的技术
