Technical Field

The invention relates to the field of limestone slurry preparation, in particular to an intelligent optimization system of a limestone slurry production line.

Background

The thermal power plant can produce some sulfides when burning coal to provide heat energy, and the thermal power plant generally uses limestone slurry to absorb sulfides to reduce the environmental pollution, the limestone-gypsum wet flue gas desulfurization process is a desulfurization technique which is widely applied at present, and the principle is that limestone powder is made into slurry which is used as a desulfurization absorbent and is contacted and mixed with flue gas entering an absorption tower, sulfur dioxide in the flue gas is chemically reacted with calcium carbonate in the slurry and blown oxidizing air, and finally gypsum is generated. Wherein, the preparation flow of the limestone slurry is as follows: the limestone slurry solid raw material is transported to a factory area by a ship or vehicle transportation mode, is pneumatically transported to a limestone slurry solid raw material bin for storage, enters a limestone slurry tank through an electric screw feeder, is mixed with pulping process water to prepare limestone slurry with preset density, and is transported to an absorption tower area through a limestone slurry pump device.

The team relies on chemical laboratory research teams and chemical plant resources in colleges and universities to research limestone slurry production and preparation process flows, particularly limestone slurry precipitation product extraction for a long time, and a large number of searches show that the existing prior art such as the prior art discloses JP2016203121A, JPS6372323A, CN728214B and WO2013082856A1, and the conventional limestone slurry preparation system is as follows: quicklime powder or limestone powder is placed in the raw material bin to serve as a solid raw material, a discharge port of the raw material bin directly falls into the limestone slurry tank through the vertical short pipe, and the limestone slurry with qualified concentration is prepared by fully stirring and mixing with pulping water in the limestone slurry tank. The temperature of system pulping water for preparing limestone slurry by taking limestone powder as a raw material is usually about 40-50 ℃, however, the process of preparing limestone slurry by taking quick lime as a raw material is an exothermic reaction, the existing limestone slurry is stirred by adding water for one time after the weight of solid raw materials and the weight of water are respectively calculated, and then the lime is mixed into the existing limestone slurry, at the moment, in the stirring process, the detection and metering error of a thermal instrument is increased due to excessively high temperature, and even the weight loss of a metering scale can be caused, so that the concentration change of the lime slurry can be greatly caused, and the normal work of each electronic mechanical device in a limestone slurry tank is influenced. In the production process, due to insufficient stirring in the limestone slurry tank, the prepared limestone slurry has limestone powder mass solids which are not reacted, so that the quality of the limestone slurry is poor. Because the limestone slurry is turbid liquid, in the process of transporting the limestone slurry, particularly when the transport pipeline is horizontally transported, the deposition of the limestone slurry is generated in the transport pipeline and is accumulated, so that the transport pipeline is blocked and the concentration of the obtained limestone slurry is lowered, the sealing of the transport pipeline is particularly important for the production of the limestone slurry, but the periodic preventive inspection of the transport pipeline is time-consuming and labor-consuming for operators due to the large cross-sectional area range, the staggered height and the non-centralization of the transport pipeline.

The invention aims to solve the problems that in the traditional limestone slurry production and preparation process flow, the precipitation and accumulation of limestone slurry blocks a conveying pipeline in the transportation process, the limestone slurry is not fully dissolved in a stirring reaction chamber, a large amount of heat is released by the limestone slurry in the reaction process, so that the cooling cost is high, the maintenance and the inspection of the conveying pipeline are inconvenient, the cost is high and the like.
