Weichai group SDS sodium based dry desulfurization project
At present, the foundry of Weichai group is equipped with two long-life hot blast water-cooled oxygen enriched blast cupola, one of which is EC & s of USA （Electric Controls and Systems ，Inc ）The company provides that the furnace type is relatively rare in China, and it is difficult to find a second set of furnace type with the same volume in China. Weichai group after a number of technical consultation and investigation, Shandong Mingsheng environmental protection SDS Sodium based dry desulfurization technology is highly recognized.
In view of the special operating conditions of Weichai cupola and large fluctuation of flue gas temperature, Shandong Mingsheng environmental protection expert group According to the operation condition of the cupola in Weichai foundry, the "Mingsheng SDS" Based on the "sodium based dry desulfurization" process, the environmental protection engineering design is customized. The original cupola flue is used for desulfurization treatment. The injection system of the desulfurization system is arranged in the high and low temperature areas of the flue gas. The flue gas after desulfurization goes through the bag filter, and the dust removed flue gas returns to the original cement chimney for discharge, After flue gas desulfurization treatment, the net flue gas SO2 is reduced Emission concentration ≤ 40mg / nm 3, improve the performance and effect of the existing bag filter.
