Abstract

The invention provides a circulating fluidized bed and a circulating fluidized bed system, and relates to the technical field of material drying. The circulating fluidized bed comprises a feeding anddischarging section. The feeding and discharging section comprises a sieving plate, a rotating shaft and a sealing assembly. The rotating shaft is arranged on the tube wall of the feeding and discharging section in a rotatable mode. The sieving plate is arranged on the rotating shaft so that the rotating shaft can drive the sieving plate to rotate. The sealing assembly is arranged inside the tubewall of the feeding and discharging section. The edge of the sieving plate abuts against the sealing assembly. The technical problems that the filtering section of a circulating fluidized bed in the prior art is high in position, the fluidized state section is insufficient in space, the material drying effect is poor, the distance between a filter screen and the fluidized state section is small and filtering pressure is large are solved.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a circulating fluidized bed and a circulating fluidized bed system. Background technique [0002] In the existing circulating fluidized bed equipment, hot air enters the equipment through the air inlet at the bottom, drives the fluidization of the material through the sieve plate, and the water vapor in the material is discharged upward through the filter device. After the material is dried, the material fluidized layer will be separated from the upper and lower air inlet and filter sections, disassembled separately, and the material in the fluidized layer will be taken out manually. [0003] There are some problems in the existing circulating fluidized bed, and the improvement is continued. This improvement aims to solve the problems of energy saving of the fluidized bed, small space in the fluidized state area, time-consuming and labor-consuming discharge of materials, ...
