Embodiment Construction

[0037] The utility model relates to a gas distribution device for fluidized materials in a fluidized bed. The fluidized bed usually has a space for accommodating fluidized materials, and an air distribution plate or air distribution device for installing a gas distribution device, ie, an air cap, and the lower part of the air distribution plate or air distribution device is used for introduction and mixing. A plenum or bellows for fluidizing gas.

[0038] As shown in the figure: The shape of the adjustable resistance gas distribution device is cylindrical, and it is divided into upper and lower parts. The inlet pipe 3 for guiding the fluidizing gas from the bellows or plenum into the resistance-adjustable gas distribution device. The distribution head 1 and the air inlet pipe 3 are coaxially arranged and connected by threads.

[0039]The upper section or top of the dispensing head 1 is processed into a nut-like polygonal column 13 with at least three faces, so as to facilita...

Abstract

The resistance adjustable gas distribution equipment for fluidized material mainly includes gas intake pipe and gas nozzle, the upper portion of the gas intake pipe is equipped cap-like distribution head which is coaxially arranged with gas intake pipe and is screw-connected with it, between the inner wal of cap-like distribution head and outer wall of gas intake pipe a gas flowing cavity is formed, on the distribution head are opened gas nozzle orifices which use axis of the distribution head as centre and are radially distributed on the side wall of the cap-like distribution head, the upperpart of gas intake pipe is extended into the the interior of cap-like distribution head cavity, and between them a gas resistance adjustable cavity strucure is formed.

Description

technical field [0001] The invention relates to a resistance-adjustable gas distribution device for fluidized materials, which is a gas distribution device for fluidized materials in a fluidized bed. Background technique [0002] The gas distribution device is one of the most important components in the fluidized bed, especially for the circulating fluidized bed, the resistance characteristics of the gas distribution device and the rationality of the structural arrangement directly affect the air distribution of the air distribution board or air distribution device. Homogeneity and the ability to build a fluidized bed with good flow characteristics. Resistance ΔP of the gas distribution device f , bed material resistance ΔP s The relationship between the total resistance ΔP of the fluidized bed is shown in Figure 10 , 11 . In the picture: [0003] ΔP=P f +ΔP s [0004] When the fluidizing gas passes through a bed filled with a certain number of solid particles from ...
