Problems solved by technology

The temperature of the pulping water in this system is usually about 40-50°C, and a certain amount of water vapor will be generated. The water vapor will enter the screw weighing feeder along the vertical short pipe, causing limestone powder to be Adsorption inside the feeder and the drop pipe will affect the accuracy of the screw weighing and feeding, resulting in deviations in the supply of limestone powder, and in severe cases, blockage

Abstract

The invention provides a preparation system of limestone slurry. A dust collector is arranged in a storage bin of the system; the bottom of the storage bin is communicated to a spiral feeding machinethrough a discharging pipeline; the spiral feeding machine is internally connected with a spiral packing auger in a rotary manner; one end of the spiral packing auger is fixedly connected to a feedingmotor; an outlet of the spiral feeding machine passes through a pipeline and the pipeline is provided with a scraping assembly; the scraping assembly comprises a scraping plate and a retractable part; a fixed end of the retractable part is fixed above the pipeline; a movable end of the retractable part is fixedly connected to the scraping plate; an edge of the scraping plate is in sliding connection with an inner pipe wall of the pipeline; the pipeline is communicated to a stirring barrel and the stirring barrel is provided with a lime stirring device; one side of the stirring barrel is communicated with a liquid outlet pipe. According to the preparation system, the spiral feeding machine is used for feeding the stirring barrel; the scraping assembly is used for preventing the pipeline from being blocked and the supply amount of the limestone slurry is accurate.

Description

technical field [0001] The invention relates to the technical field of industrial flue gas desulfurization, in particular to a limestone slurry preparation system. Background technique [0002] The conventional limestone powder mixing system is: a screw weighing feeder is installed at the outlet of the limestone powder bin, and after being weighed by the screw, the limestone powder directly falls into the limestone slurry tank through a short vertical pipe, and is mixed with the slurry in the limestone slurry tank. The water is fully stirred and mixed to make a limestone slurry with a qualified concentration. The temperature of the pulping water in this system is usually about 40-50°C, and a certain amount of water vapor will be generated. The water vapor will enter the screw weighing feeder along the vertical short pipe, causing limestone powder to be Adsorption inside the feeder and the drop pipe will affect the accuracy of the screw weighing and feeding, resulting in a d...
