Absorption tower slurry pool disturbance device

Abstract

The invention discloses an absorption tower slurry pool disturbance device which comprises a gas disturbance device arranged in a circular slurry pool. The gas disturbance device comprises a gas distribution pipe, a gas nozzle and a gas distribution pipe, the gas distribution pipe is annularly arranged in the slurry pool and is concentric with the slurry pool, the gas nozzle is arranged on the gasdistribution pipe, the included angle between the gas nozzle and the gas distribution pipe is theta and smaller than 90 degrees, a nozzle of the gas nozzle is located below the liquid level of slurry, the gasdistribution pipe is connected with the gas distribution pipe, and the gas distribution pipe is connected with a high-pressure gas source. The device is simple in structure, safe, reliable, capable of promoting slurry to flow without dead zones, capable of avoiding slurry precipitation and scaling, high in dust removal efficiency, beneficial to oxidative crystallization and low in operation and maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of flue gas desulfurization and denitrification equipment, and in particular relates to a disturbance device for a slurry pool of an absorption tower. Background technique [0002] In order to prevent the slurry in the absorption tower from depositing and scaling in the tank, a mixer is often used to stir the slurry, and the flow of the slurry promotes the uniformity of the oxidizing air, which is beneficial to the reaction in the slurry. However, the stirring blades of the mixer are easy to corrode in the slurry. After the stirring blades are corroded and worn, a flow dead zone is often formed in the pool, resulting in sediment scaling, affecting the oxidation reaction and reducing the quality of subsequent crystals. At the same time, the oil seal of the mixer is easy to wear and leak, resulting in high failure rate and shutdown. The entire processing line needs to be stopped during maintenance, affecting p...

Problems solved by technology

However, the stirring blade of the mixer is easy to corrode in the slurry. After the mixing blade corrodes and wears, it often forms a flow dead zone in the pool, causing sedimentation and scaling, affecting the oxidation reaction and reducing the quality of subsequent crystals. At the same time, the oil seal of the mixer is easy to wear and leak, resulting in high failure rate and shutdown The entire processing line needs to be stopped during maintenance, affecting production; dust particles and grease brought into the slurry by flue gas will also affect oxidation and crystallization
