[0002] Desulfurization towers are tower-type equipment used to desulfurize industrial waste gas. Originally constructed of granite, these towers were the most widely used. They utilize the principle of water film desulfurization and dust removal, and are also known as granite water film desulfurization dust collectors or granite water film desulfurization dust collectors. They are easy to maintain and can achieve both dust removal and desulfurization simultaneously by combining various dust removal agents. Currently, desulfurization methods are categorized into dry and wet desulfurization, with equipment selection tailored to specific operating environments and specific circumstances.
