Abstract

The invention discloses a continuous heat transfer sulfur dioxide converter, which comprises a shell, and a catalyst layer in the shell, wherein the catalyst layer is supported by a grate; the shell below the grate is provided with a smoke outlet; a plurality of internal heat transfer pipes in rows are densely arranged in the catalyst layer; two ends of each heat transfer pipe penetrate the shell and are connected with a heat transfer header pipe; a great amount of heat released in reaction is transferred by the internal heat transfer pipes and is fully utilized; equipment is not corroded; the traditional conversion flow is simplified; and the equipment size is greatly reduced, and the occupied area is reduced.

Description

technical field [0001] The invention relates to a continuous heat removal sulfur dioxide converter. Background technique [0002] Non-ferrous smelting enterprises pyrometallurgically smelt such as copper, nickel, lead, zinc, etc., and the raw materials are mostly sulfide ores. The traditional treatment method for the tail gas after smelting is to purify and remove dust and then oxidize it to produce sulfuric acid. With the advancement of smelting technology, smelting enterprises generally adopt the continuous smelting process of oxygen-enriched or industrial air, so flue gas with high concentration of SO2 is produced, which puts forward higher requirements for flue gas acid production equipment. For example, according to the existing acid-making process, it is necessary to dilute the smelting flue gas to a concentration of SO2 of about 12%, which will increase the size of the acid-making plant by 3 to 5 times, and the construction investment and operating costs of the corres...
