Description

technical field [0001] The invention relates to the field of preparing limestone slurry, in particular to an intelligent optimization system for a limestone slurry production line. Background technique [0002] Thermal power plants will produce some sulfides when burning coal to provide heat energy, while thermal power plants generally use limestone slurry to absorb sulfides to reduce environmental pollution. Limestone-gypsum wet flue gas desulfurization process is currently the most widely used one Desulfurization technology, the principle is to use limestone powder to make slurry as a desulfurization absorbent, contact and mix with the flue gas entering the absorption tower, the sulfur dioxide in the flue gas chemically reacts with the calcium carbonate in the slurry and the oxidized air blown in, and finally produces plaster. Among them, the preparation process of limestone slurry is as follows: the solid raw material of limestone slurry is transported to the factory are...

Problems solved by technology

The temperature of the pulping water in the system for preparing limestone slurry from limestone powder is usually about 40-50°C. However, it is an exothermic reaction to prepare limestone slurry from quicklime. The existing limestone slurry is prepared by separate After calculating the weight of solid raw materials and water, add enough water at a time, and then mix it with lime for stirring. At this time, during the stirring process, the excessive temperature will make the measurement error of the thermal instrument increase, and even cause the weighing scale to lose weight, that is, It may cause a large change in the concentration of the lime slurry, which will affect the normal operation of the electronic and mechanical devices in the limestone slurry tank

During the production process, due to insufficient stirring in the limestone slurry tank, the prepared limestone slurry will have unreacted limestone powder solids, resulting in unqualified limestone slurry quality

Since the limestone slurry is a suspension, during the transportation of the limestone slurry, especially when the transportation pipeline is horizontally transported, the sediment of the limestone slurry will accumulate in the transportation pipeline, resulting in the blockage of the transportation pipeline and the low concentration of the obtained limestone slurry. The sealing of the pipeline is particularly important for the production of limestone slurry. However, due to the large crossing area of ​​the transportation pipeline, the heights are scattered, and the concentration is not concentrated, the regular preventive inspection of the transportation pipeline is extremely time-consuming and laborious for the operators.

[0004] In order to solve the common problem in this field in the traditional limestone slurry production and preparation process, the sedimentation and accumulation of the limestone slurry during the transportation process blocks the transportation pipeline, the limestone slurry is not fully dissolved in the stirring reaction chamber, and the limestone slurry releases a large amount of heat during the reaction process, which leads to high cooling costs. To solve these problems such as inconvenient maintenance and inspection of pipelines and high cost, the research team has made the present invention
