Device for preparing sulfur dioxide by directly burning raw sulfur

Abstract

The invention discloses a device for preparing sulfur dioxide by directly burning raw sulfur. The device for preparing the sulfur dioxide by directly burning the raw sulfur comprises a raw sulfur continuous burning furnace; a sulfur noodle extrusion molding machine is arranged on the top of the raw sulfur continuous burning furnace; the sulfur noodle extrusion molding machine is connected with a propulsion feeder; and a raw sulfur funnel is arranged on the propulsion feeder. By the device for preparing the sulfur dioxide by directly burning the raw sulfur, the technical problem that the raw sulfur is difficult to burn and cannot be burned totally is solved effectively; the amorphous, flowable and difficult burning characteristics of the raw sulfur are changed into moldable, static and incendive characteristics, so that the raw sulfur can be burned and is easy to burn, and SO2 can be prepared directly; meanwhile, the high-performance retention high-temperature gas heat is recycled, so a feasible method for treatment and economic utilization of the raw sulfur is found. The device is a reliable way for relieving the burden of the environment as the raw sulfur is continuously increased; and the device has better economic prospect and good social benefit.

Description

technical field [0001] The invention relates to an incineration process device for generating sulfur produced by wet desulfurization, in particular to a device for directly incinerating raw sulfur to prepare sulfur dioxide. Background technique [0002] Sulfur, usually referring to cooked sulfur or crystalline sulfur or elemental sulfur, is one of the main raw materials for the production of sulfur dioxide or sulfuric acid. At room temperature, sulfur is solid, brittle, easily brittle, well dispersed and flammable. Sulfur, commonly known as sulfur paste, has an amorphous shape, low sulfur content, high water content, easy flow, amorphous, and difficult to burn. Therefore, factories that produce sulfur dioxide such as sulfuric acid plants do not use raw sulfur as raw materials. The desulfurization and decyanation of coal gas in coking plants in China mostly adopts the wet catalytic oxidation desulfurization process. There are two ways to treat the generated sulfur bubbles, ...
