Embodiment Construction

[0037] The invention is a gas distribution device for fluidized materials in a fluidized bed. The fluidized bed generally has a space to accommodate fluidized materials, and an air distribution plate or air distribution device for installing a gas distribution device, that is, an air cap. Below the air distribution plate or air distribution device is used for introducing and mixing Air chamber or bellows for fluidizing gas.

[0038] As shown in the figure: the adjustable resistance gas distribution device has a cylindrical shape and is divided into upper and lower parts. It is used to guide the fluidizing gas from the bellows or wind chamber into the air intake pipe 3 of the resistance-adjustable gas distribution device. The distribution head 1 and the air inlet pipe 3 are coaxially arranged and threaded.

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

Abstract

The invention is an adjustable resistance gas distribution device for fluidized materials, which mainly includes an air inlet pipe and a gas nozzle. On the upper part of the air inlet pipe, there is a cap-shaped distribution head arranged coaxially with the air inlet pipe and screwed to it. The cap There is a gas flow chamber between the inner wall of the distribution head and the outer wall of the intake pipe. There are gas nozzles on the distribution head. into the cavity of the cap-shaped distribution head, forming an adjustable gas resistance cavity structure between the cap-shaped distribution head and the cap-shaped distribution head. The diameter of the gas nozzle is between φ5 ~ 25mm, and the nozzles are evenly distributed around the distribution head. The nozzles can be arranged in a single layer or in multiple layers along the height direction of the hood, and there is at least one air inlet of the bottom layer of nozzles. flush with the bottom inside surface of the dispense head. The angle α between the spout and the horizontal plane is generally in the range of 0° to 30°.

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 parts 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 plate or the air distribution device. Uniformity and the ability to establish a fluidized bed with good flow characteristics. Resistance ΔP of gas distribution device f , bed material resistance ΔP s and the relationship between the total resistance ΔP of the fluidized bed bed see 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 amount of solid particles from bo...
