Fluidized bed production system for powder products

Abstract

The invention discloses a fluidized bed production system for powder products, wherein the system comprises a sulfonation neutralization system, a batching kettle, a gas furnace, a fluidized bed, a cyclone separator, a cloth bag separator and a tail gas treatment system; the fluidized bed is an annular fluidized bed, the bottom of the fluidized bed is provided with a first gas inlet, the side wall of the fluidized bed is provided with three second gas inlets, and the three second gas inlets are horizontally arranged along the horizontal tangent line of the fluidized bed; the tail gas treatment system comprises a primary treatment device and a secondary treatment tower; the primary treatment device comprises a pool body and a gas conveying pipe arranged in the pool body, a first partition plate is arranged in the pool body, and a plurality of first through grooves and first sealing plates used for sealing the first through grooves are arranged on the first partition plate; and a second through groove is formed in the first sealing plate, a motor used for driving the gas conveying pipe to rotate is arranged on the pool body, and the first sealing plate rotates along with rotation of the gas conveying pipe.

Description

technical field [0001] The invention belongs to the technical field of powder product production, and in particular relates to a fluidized bed production system of powder product. Background technique [0002] The production process of powder products requires the use of a fluidized bed. Generally, dry particles are used to dry the slurry in the fluidized bed. However, when the fluidized bed is used, the clean particles, wet particles with material, and semi-dry particles are all in the same space, which is easy Partial or total dead bed phenomenon occurs, and the entire processing step needs to be shut down for repair, which reduces the powder production efficiency; the tail gas generated during powder production is directly passed into the lye for neutralization, and the tail gas enters the lye and quickly from the lye Scattered, the tail gas does not fully react with the lye, and the tail gas treatment effect is not good. Contents of the invention [0003] In order to ...
