Application Of Zenith Mill In FGD System

In recent years, most areas have been affected by smog and weather. Thermal power plants are one of the main channels for air pollution. With the increasing national efforts on environmental protection and increasing attention to sulfur dioxide emissions from thermal power plants, the State Environmental Protection Administration requires that thermal power enterprises must build supporting desulfurization and denitrification devices. Major thermal power plants also pay more and more attention to desulfurization systems. How to choose the appropriate desulfurization process and desulfurization equipment has become the primary concern of power plant equipment purchasers.dxTUltrafine Grinder, Ultrafine Mill For Sale

Commonly used in the desulfurization process are limestone-gypsum flue gas wet desulfurization, flue gas circulating fluidized bed, water film dust removal and desulfurization integration technology. Among them, limestone-gypsum desulfurization is a relatively mature and widely used technology in the world. This technology was developed in the 1940s and 50s. The flue gas desulfurization devices used in thermal power plants in the United States, Japan, and Germany are about 90 % Uses this process.dxTUltrafine Grinder, Ultrafine Mill For Sale

Limestone-the working principle of gypsum desulfurization is: grinding large pieces of limestone into stone powder, and then sending it to the limestone slurry preparation system, using the limestone slurry as a desulfurization absorbent, contacting and mixing with the flue gas entering the absorption tower, in the flue gas The sulfur dioxide reacts with the calcium carbonate in the slurry and the incoming air, and finally generates gypsum to remove the sulfur dioxide in the flue gas, avoiding environmental pollution caused by large amounts of emissions. Since the absorbent slurry in the absorption tower repeatedly circulates in contact with the flue gas through the circulation pump, the absorbent utilization rate is very high. The limestone/lime method is the most widely used FGD process in the world. For high-sulfur coal, the desulfurization rate can be more than 90%, and for low-sulfur coal, the desulfurization rate can be more than 95%.dxTUltrafine Grinder, Ultrafine Mill For Sale

The limestone-gypsum flue gas wet desulfurization process mainly needs to be equipped with: special absorption towers, conveyors, demisters, heat exchangers, etc., and auxiliary desulfurization mills for auxiliary production. The main function of desulfurization mill is to produce limestone and gypsum desulfurization powder, which is an indispensable equipment. Since the limestone slurry in the absorption tower must remain active, and the activity of the desulfurization agent can only be replaced regularly, it is extremely important to equip a special desulfurization mill to process the limestone powder and then prepare an active limestone slurry. The quality, fineness, and particle distribution of limestone powder in the desulfurization agent will affect the desulfurization effect. Therefore, the selection of good mill equipment is the primary condition for manufacturing a good desulfurizer to achieve efficient desulfurization and environmental protection.dxTUltrafine Grinder, Ultrafine Mill For Sale
