Embodiment Construction

[0007] The multilayer fluidized bed provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0008] Such as figure 1 As shown, the present invention provides a kind of multilayer fluidized bed, multilayer fluidized bed, comprises shell 1 and the first porous partition 2 inside shell, and the first porous partition 2 is enclosed within shell 1 The cavity is divided into a first cavity 3 at the top and a second cavity 4 at the bottom. The porous partition 2 is provided with a discharge port 5, and the discharge port 5 is provided with a discharge baffle 6. The second cavity 4 An air inlet 7 is also arranged at the bottom, a second porous partition 8 is arranged between the air inlet 7 and the second cavity 4, and the second cavity 4 is also provided with a discharge port 9, the position of the discharge port 9 At a position higher than the second porous partition 8 , the first cavity 3 is provided with a feed p...

Abstract

The invention provides a multilayer fluidized bed. The multilayer fluidized bed comprises a shell and a first porous baffle in the shell, wherein the first porous baffle divides the inner chamber of the shell into a first chamber at the upper part and a second chamber at the lower part, a charging port is formed in the porous baffle, a feed baffle is arranged at the charging port, an air inlet is formed below the second chamber, a second porous baffle is arranged between the air inlet and the second chamber, the second chamber is provided with a discharge outlet, the position of the discharge outlet is higher than the position of the second porous baffle, the first chamber is provided with a feed inlet and an air outlet is formed in the upper part of the first chamber. The multilayer fluidized bed provided by the invention has the advantages that since the multilayer chambers are provided and materials are in a boiling state, the materials are not apt to dry and harden; since countercurrent heat and moisture exchange conditions are provided, the utilization ratio of dry and hot air is greatly improved and the energy utilization ratio is improved.

Description

technical field [0001] The invention relates to the field of dryer equipment, in particular to a multilayer fluidized bed equipment. Background technique [0002] The current fluidized bed mostly adopts the van type drying fluidized bed when drying granular objects. Since the van type drying fluidized bed works in gaps, it is inconvenient to use, and it is easy to dry out when a large amount of wet material enters the system, which affects the heat and humidity exchange. uniformity. Contents of the invention [0003] The purpose of the present invention is to provide a multi-layer fluidized bed, which solves the problems of easy dryness and poor uniformity of heat and humidity in the above-mentioned prior art problems. [0004] The present invention provides a multi-layer fluidized bed, comprising a shell and a first porous partition inside the shell, the first porous partition divides the inner cavity of the shell into a first cavity located at the upper part and a first...
