Energy-saving vortex fluidized bed

Abstract

The invention discloses an energy-saving vortex fluidized bed, which comprises a fluidized bed tube body, wherein the fluidized bed tube body comprises an air inlet pipe, a material bed, a fluidized bed, cyclone separators and an air outlet; the side surface of the bottom end of the fluidized bed tube body is provided with the air inlet pipe; the top end of the fluidized bed tube body is providedwith the air outlet; the material bed, the fluidized bed and the cyclone separators are sequentially arranged inside the fluidized bed tube body from bottom to top; the two cyclone separators are arranged in parallel inside the fluidized bed tube body; each cyclone separator comprises a cyclone device and a flow divider; the cyclone device is arranged inside a flow divider tube body; an air dividing tube is arranged inside a cyclone device tube body; an air energy heat exchanger is used for segmented heating. The novel cyclone separators are installed for replacing the original cloth bags fordust removal, so that the dust removal effect is better; no consumable exists; the component replacement is not needed; an air energy segmented heating method is used, so that the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of fluidized beds, in particular to an energy-saving vortex fluidized bed. Background technique [0002] When the velocity of the fluid passing through the bed gradually increases to a certain value, the particles will loosen, the gaps between the particles will increase, and the volume of the bed will expand. If the fluid velocity is further increased, the bed will not be able to maintain a fixed state. At this time, all the particles Suspended in the fluid, it shows quite irregular movement. As the flow rate increases, the movement of the particles becomes more intense, and the expansion of the bed increases accordingly, but the particles still stay in the bed without being driven by the fluid. This state of layers, similar to liquids, is called a fluidized bed. [0003] In the pharmaceutical, chemical, food and other powder product industries, fluidized beds are used to process products. The top of the f...
