Problems solved by technology

The traditional mechanical agitation for lime digestion is to add water to the mixer to mix and digest quicklime powder and water to produce quicklime. The quicklime produced by this method is not fully digested and cannot meet the requirements of a uniform fluffy dry powder.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] Such as figure 1 , 2 , Shown in 3, a quicklime digestion system includes a hopper 1, an inspection door 2, a feeder 3, a screw conveyor 5, and a primary digester 9, and the inspection door 2 is normally open, and is closed when the system fails. The feeder 3 is set under the hopper 1 through the inspection door 2, the screw conveyor 5 is connected under the feeder 3, the first-stage digester 9 is connected to the lower end of the screw conveyor 5, and the one A water inlet pipe 8 is provided on the first-stage digester 9, and a water supply valve 15, a flow meter 13 and a flow regulating valve 14 are arranged in sequence on the water inlet pipe 8, which can be adjusted according to the actual amount of quicklime and the moisture content of the final product slaked lime. Water volume; the function of the flowmeter 13 is to accurately measure the actual water supply....

Abstract

The present invention provides a quicklime slaking system, including a hopper, a feeder, a screw conveyor, and a tertiary slaker. The feeder is arranged below the hopper. The screw conveyor is connected below the feeder. A primary slaker is connected with the lower end of the screw conveyor. A secondary slaker and the tertiary slaker are sequentially connected below the primary slaker. The primary slaker is provided with a water inlet pipe. The water inlet pipe is sequentially designed with a water feeding valve, a flow meter and a flow control valve. The system controls the moisture content of the final product slaked lime by adjusting the amount of inflow water, therefore the quicklime is slaked into fluffy lime powder.

Description

technical field [0001] The invention relates to a quicklime digestion system, in particular to a quicklime digestion system used in flue gas desulfurization, and belongs to the technical field of flue gas desulfurization. Background technique [0002] As my country controls and reduces SO 2 With the continuous increase of emissions, flue gas desulfurization has entered a stage of rapid development, and the existing dry desulfurization and semi-dry desulfurization are mostly produced by mechanical stirring. The traditional mechanical agitation for lime digestion is to add water to the mixer to mix and digest quicklime powder and water to produce quicklime. The quicklime produced by this method is not fully digested and cannot meet the requirements of uniform fluffy dry powder. Contents of the invention [0003] The object of the present invention is to provide a quicklime digestion system. The system controls the water content of the final finished slaked lime by adjusting...
