Limestone Ultrafine Powder Desulfurization Process

 The limestone ultrafine powder desulfurization process is: firstly, the limestone ultrafine powder containing more than 50% of calcium and having a fineness of 325 mesh or more is slurried, and the O2 in the coal-fired flue gas is filtered out, thereby achieving coal burning in the power plant. In this process, the quality of limestone ultrafine powder is a key factor in the high efficiency of desulfurization and environmental protection.

On the basis of surveying the customer's on-site production situation, our company's experts designed a limestone desulfurization and milling production line with a 95% desulfurization rate according to the customer's special requirements. First of all, we must ensure that the limestone ultra-fine grinding system process is effectively operated for 20 hours every day, and then select the model and specifications of the ultra-fine mill according to the required Taiwan time production, and allocate 2500-3000 m3 ventilation according to the mill output and the output per ton. , select the model and specifications of the corresponding dust collector from the calculated total ventilation. The system uses the fan to select the specification and model according to the system air volume, resistance and temperature. The size of the hot blast stove is designed according to the heat balance calculation result.

The line not only benefits from a reasonable process and equipment configuration, but also the high performance of its ultra-fine mill. The machine has a high degree of automation, and the thin oil lubrication, automatic control device and limit device ensure the stable operation of the equipment. The finished coal powder prepared by the mill has stable chemical composition, high fineness level and reasonable particle gradation. Moreover, the machine has low cost input and strong drying ability, and the production adopts a fully sealed system, no dust and clean environment.
