Desulfurization equipment in power plant
Process flow of desulfurization equipment in power plant
Block limestone is crushed to the required particle size by jaw crusher, then sent to storage hopper by bucket elevator, denitrated by power plant, and then sent to mill by vibrating feeder for grinding. The ground limestone powder is blown by the wind and classified by a classifier. Limestone powder with qualified fineness enters the cyclone powder collector for separation and collection along with the airflow through the pipeline. The collected limestone powder products are sent to the stone powder warehouse by the conveying device for desulfurization. Unqualified particles are separated by the classifier and thrown to the cylinder wall, and fall behind the cylinder wall and return to the mill for grinding. The whole system runs under negative pressure, and the dust will not overflow, thus ensuring the cleanliness.
The whole process of desulfurization equipment in power plant is stable, with low investment and easy production management. When selecting production process scheme and equipment selection, adopt mature and reliable new processes and technologies to achieve advanced technology, economic rationality and reliability. The control level of electrical automation should be reliable and practical. We attach great importance to the comprehensive management of the environment and can meet the national standards.

Using traditional power plant desulfurization equipment to prepare limestone powder has high energy consumption, low output, complex technological process and difficult control of fineness and particle gradation. After years of painstaking research and development, Liming Heavy Industry experts have successively introduced patented products such as overpressure trapezoidal mill, European trapezoidal mill and vertical roller mill, which set off a new revolution in the field of desulfurization equipment in thermal power plants.
The process flow of desulfurization equipment in power plant is simple and the degree of automation is high; Low energy consumption (20~30% lower than traditional mill), high output and little wear; Low noise, less dust and clean operating environment; The product has stable chemical composition, uniform particle gradation and adjustable fineness, and can be well filled with appropriate amount of limestone powder required for flue gas desulfurization, thus improving desulfurization efficiency.
