Which mill is the best for desulfurization in power plants?
Limestone-gypsum flue gas desulfurization wet process (FGD) and boiler internal calcium injection technology are currently mature and widely used SO2 emission control technologies in the world. More than 90% of domestic thermal power plants use limestone-gypsum wet desulfurization.
Limestone-gypsum wet desulfurization requires the production of a desulfurizer, which is mainly composed of limestone powder or calcium powder and mixed slurry of other stone powders and water, among which limestone powder is widely used. The fineness of limestone powder required by wet desulfurizer is usually 250 mesh 91% sieving rate, or 325 mesh 90% sieving rate.
SMMVIK VM vertical pulverizer and MTW European version pulverizer have simple process flow and high degree of automation; low energy consumption (20~30% lower power consumption than traditional pulverizers), high output and low wear Less dust, clean operating environment; stable product chemical composition, uniform particle gradation, adjustable product fineness (80-425 mesh), can be well filled with suitable limestone powder required for flue gas desulfurization, and improve desulfurization efficiency.
MTW series European version grinding machine: Raymond mill upgrade equipment, is a new grinding equipment with international technical level and a number of independent patent technology property rights developed by SMMVIK authoritative experts absorbing new European grinding technology and concepts. The model adopts a number of new patented technologies such as bevel gear integral transmission, internal thin oil lubrication system, and arc air duct.
VM Vertical Roller Mill: It adopts a reasonable and reliable structural design and cooperates with the technological process, integrating drying, grinding, powder selection and upgrading, especially in the large-scale grinding process, which fully meets the needs of customers. The main technical and economic indicators have reached the international level.
Specific customers can choose and configure according to output, site and amount. All are very suitable and can meet the application requirements of power plant desulfurization pulverizers.
In addition to high-performance equipment, SMMVIK has also launched an overall solution for the desulfurization and pulverizing system of thermal power plants. From the initial raw material testing to the later installation, commissioning, acceptance and production, SMMVIK provides full guidance and production testing of main and auxiliary equipment, and has A professional technical service team will carry out post-system maintenance for you. At present, SMMVIK has designed and established nearly 100 wet desulfurization process production lines for large power plants at home and abroad, and the customer feedback is good.
