Abstract
A labyrinth gas-solid fluidizing bed pertains to the field of drying device, mainly consisting of a labyrinth passage baffle, a labyrinth passage gas distributing plate, a tank body, a granules material inlet, a granules material outlet, a fluidizing gas inlet and an exhaust outlet. The labyrinth passage baffle, the tank body as well as the labyrinth passage gas distributing plate form into a labyrinth gas-solid fluidizing passage, and realize a stably fluidizing operation of the granules material in the fluidizing bed with the bed width more than 1 to 2 meters, without non-uniform phenomena of current bias or channel flow. The utility model has the advantages of simple structure, simple manufacture and operation convenience.
Description
The labyrinth type gas-solid fluidized bed belongs to drying device field.
As everyone knows, common gas-solid fluidized bed mainly is made up of gas distribution grid, casing, granule materials import, grain products outlet, fluidizing gas import and waste gas outlet etc.Solid particle material adds from charging aperture one end of fluid bed, makes solid particle be in fluidized state in bed through the uniform gas of gas distribution grid, discharges from the discharging opening of the other end by potential difference.For preventing vertical back-mixing of particle, several plate washers perpendicular to gas distribution grid (claiming dividing plate again) usually are set in bed, bed is divided into several cells in the longitudinal direction, therefore claim horizontal multi-cell fluidized bed again.When the bedside of horizontal multi-cell fluidized bed during greater than 1～2m, non-uniform phenomenons such as bias current, channel will appear in the material bed, make operating process be difficult to stably carry out.
The purpose of this utility model provides a kind of labyrinth type gas-solid fluidized bed, and the baffle plate of horizontal multi-cell fluidized bed is arranged to the labyrinth channel dividing plate, and gas distribution grid is arranged to the labyrinth channel gas distribution grid.Labyrinth channel dividing plate, labyrinth channel gas distribution grid and casing have constituted mazy gas-solid fluidization passage.Realize granule materials bedside greater than the fluid bed of 1～2m in fluidisation equably, operating process is stably carried out.
The realization the technical solution of the utility model is: the baffle plate of horizontal multicell gas-solid fluidized bed is arranged to the labyrinth channel dividing plate, and gas distribution grid is arranged to the labyrinth channel gas distribution grid.Labyrinth channel dividing plate, labyrinth channel gas distribution grid and casing have constituted the gas-solid fluidization passage of labyrinth type.The gap that 30～60mm is arranged between the baffle plate of horizontal multicell gas-solid fluidized bed and the gas distribution grid, granule materials flows to next cell by this gap by a cell; The labyrinth channel dividing plate then is directly to be connected with the labyrinth channel gas distribution grid.Baffle plate is full of whole bedside, and the labyrinth channel dividing plate directly is connected with a side of casing on one side, the spacing distance of another side and casing opposite side equals the distance (being the labyrinth passage width) between the labyrinth channel dividing plate, the geometry of next the labyrinth channel dividing plate that is adjacent is identical, and just the labyrinth channel dividing plate is connected with the opposite side of casing.The duct direction of common fluid bed gas distribution grid is identical, and the duct direction of labyrinth channel gas distribution grid of the present utility model and its labyrinth passage are complementary.
The utility model realized granule materials at bedside greater than the stabilization of fluidized operation in the fluid bed of 1～2m, and non-uniform phenomenons such as bias current, channel do not appear.Of the present utility model simple in structure, easy to manufacture, easy to operate.
