Title:
SWIRLING AIR-DISTRIBUTION FLUIDIZED BED
Document Type and Number:
WIPO Patent Application WO/2021/073436
Kind Code:
A1
Abstract:
A swirling air-distribution fluidized bed, comprising a swirling air-distribution mechanism (20). The swirling air-distribution mechanism (20) comprises a support plate (21), a fixed plate (22), and several air-distribution plates (23). The support plate (21) is of a circular structure. Each of the air-distribution plates (23) is separately connected to the support plate (21) and the fixed plate (22). The serval air-distribution plates (23) are circumferentially distributed on the periphery of the support plate (21). The support plate (21), the fixed plate (22), and all the air-distribution plates (23) constitute the circular structure. The air-distribution plate (23) comprises a first horizontal portion (231), an inclined portion (232), and a second horizontal portion (233) which are connected to each other in sequence. The first horizontal portion (231) is parallel to the second horizontal portion (233). A first horizontal portion (231) of one of any two adjacent air-distribution plates (23) and a first horizontal portion (231) of the other air-distribution plate (23) are located in the same horizontal plane. There is a gap between the first horizontal portion (231) of one air-distribution plate (23), and a second horizontal portion (233) of the other air-distribution plate (23). The swirling air-distribution fluidized bed can solve the problem of the inadequate contact of a material with the hot air caused by the existing air passing plate, reduce the wind resistance, avoid the bed collapse phenomenon, and prevent the material from reversely flowing to a bottom barrel (11).
