Novel industrial fluidized bed device

Abstract

The invention discloses a novel industrial fluidized bed device which comprises a fluidized bed body, a stock bin, a spiral feeding shell, a first air inlet hopper, a heater, a cyclone separator and abag type dust collector, wherein a fluidizing chamber is arranged in the fluidized bed body, a feed inlet is formed in one side of the fluidized bed body, the spiral feeding shell is mounted in the feed inlet, one end of the spiral feeding shell extends into the middle of the fluidizing chamber, the stock bin is mounted on the upper side of one end of the spiral feeding shell, a feeder is mountednext to the stock bin, a first discharge port is formed in one side of the bottom of the fluidized bed body, the first air inlet hopper and a second air inlet hopper are mounted on the lower side ofthe fluidized bed body, an air inlet branch pipe is connected to the lower side of the first air inlet hopper, one end of the air inlet branch pipe is connected to a first air inlet main pipe, and a first air blower is mounted at one end of the first air inlet main pipe. According to the novel industrial fluidized bed device disclosed by the invention, to-be-dried substances can be dried quickly,so that the efficiency is also improved while the energy sources are saved.

Description

technical field [0001] The invention relates to the field of fluidized bed technology, in particular to a novel industrial fluidized bed device. Background technique [0002] The fluidized bed suspends a large number of solid particles in the moving fluid, so that the particles have some apparent characteristics of the fluid. This fluid-solid contact state is called solid fluidization, that is, a fluidized bed. A fully fluidized bed exhibits liquid-like properties. 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 cannot maintain a stationary state. At this point, the particles are all suspended in the fluid, exhibiting rather irregular motion. As the flow rate increases, the movement of the particles becomes more violent, and the expansion of the bed increases accor...
