Description

Technical Field

[0001] The utility model relates to the technical field of boiling furnaces, in particular to a fluidized boiling hot blast furnace. Background Art

[0002] A fluidized bed furnace is a coal-fired boiler and one of the new combustion technologies developed in recent years. A modern fluidized bed furnace is a thermal equipment that uses fluidized bed technology. When the fluid flows from bottom to top through a static granular material layer, if the flow rate exceeds a certain limit, the bulk material layer begins to expand, creep, and become fluid, turning into a pseudo-fluid state. This process is called fluidization of the bulk material layer. The up and down tumbling of the fluidized granular material is similar to the boiling of the fluid, so it is also called a boiling layer. The thermal equipment that uses this method to process materials is called a fluidized bed furnace.

[0003] The utility model with the existing authorization announcement number CN216409735U discloses a boiling furnace, including a boiling furnace body. One end of the boiling furnace body extending upward is provided with a detachably connected chimney pipe. A bottom filter plate, a middle filter plate, and a high filter plate are arranged in sequence from bottom to top in the chimney pipe. Collision balls are respectively arranged between the bottom filter plate and the middle filter plate, and between the middle filter plate and the high filter plate.

[0004] The above-mentioned technical scheme is adopted, in which, through the impact of the collision ball, the unburned dust filtered on the bottom filter plate, the middle filter plate and the high filter plate will fall down with the impact, so that it will be fully burned. Also due to the impact of the collision ball, too much dust will not adhere to the filter plate, and the fallen dust will be discharged outward with the flow of hot air flow, thus avoiding the situation where a large amount of dust blocks the chimney pipe. However, the above-mentioned technical scheme is relatively simple when used, and the fallen powder residue cannot be reused, resulting in waste. Therefore, a technician in this field provides a fluidized boiling hot air furnace to solve the problems raised in the above-mentioned background technology. Utility Model Content
