Natural zinc oxide powder desulfurization is the use of natural zinc oxide powder fume in the smelting industry for desulfurization and recycling of desulfurization by-products. While treating waste with waste, it can also create certain economic benefits for enterprises. This technology has strong pertinence and is suitable for enterprises in the non-ferrous smelting industry with their own zinc oxide fume. It can treat waste with waste and reuse the waste. The selection of this technology for desulfurization mainly considers the reliable source of the desulfurizer natural zinc oxide powder and the comprehensive utilization of desulfurization by-products.

Advantages of applyingnatural zinc oxide powder desulfurization

①Low investment: Desulfurization products (zinc sulfite, zinc sulfate, etc.) can be disposed and utilized within the enterprise, and the existing production equipment (such as zinc sulfate purification, electrolysis system, zinc concentrate boiling roaster, SO2 sulphuric acid system, etc.) are used as recovery equipment for desulfurization by-products, so the investment in desulfurization equipment is small.

②Low operating cost: Using zinc oxide fume, an intermediate product of the lead-zinc smelting process, as a desulfurizer, both the zinc in the fume and the sulfur in the flue gas are converted into by-products to realize the comprehensive utilization of zinc and sulfur resources. No need to purchase desulfurizer (in other desulfurization methods, the cost of desulfurizer accounts for more than 60% of the total operating cost), saving operating costs.

②Secondary pollution occurs: the absorption product is used as the raw material for zinc production, making the absorption process a part of zinc production. Zinc and SO2 can be recycled, which truly solves the problem of SO2 emission reduction. No wasteis produced, and there is no The secondary pollution problem achieves the maximum utilization of resources and meets the requirements of the national environmental protection policy.

④High desulfurization efficiency: The zinc oxide method desulfurization efficiency is more than 97%, which can adapt to the fluctuation of SO2 in the flue gas. It is generally used for small-scale flue gas desulfurization.
