In the sulfuric acid production system of the sulfuric acid plant, exhaust gas dust removal and purification are crucial steps for ensuring environmental compliance and maintaining the facility’s continuous operation. This process typically employs a wet scrubbing method, where circulating scrubbing liquid absorbs and purifies the acidic gases and dust-laden exhaust. However, during actual operation, the scrubbing solution exhibits a complex composition, commonly containing highly corrosive ions such as fluorine and chlorine. It also carries a certain proportion of solid particles and gases, presenting issues like strong corrosion and high abrasion.<\/p>\n\n\n\n
Under these conditions, standard chemical pumps or conventional rubber-lined pumps are highly susceptible to accelerated lining wear, seal failure, and impeller corrosion. In a sulfuric acid production system’s exhaust gas dust removal and purification project for an international group, the original circulating pump’s wear parts required replacement every 7 days. Frequent shutdowns for maintenance not only increased operational costs but also severely disrupted the stable operation of the acid production process, becoming a significant challenge for the enterprise. The desulfurization circulation slurry pump<\/a> we provided has perfectly resolved their current issues.<\/p>\n\n\n
