[0002] At present, there are two production process routes for sodium metabisulfite: dry process and wet process. The traditional wet process using sulfur as raw material is as follows:

[0003] First, the sulfur is crushed into powder and sent into the combustion furnace with compressed air. It is burned at 600-800℃. The amount of air added is about twice the theoretical amount. The gas SO 2 The concentration is 10-13. After cooling, dust removal and filtration, sublimated sulfur and other impurities are removed, and the gas temperature is reduced to about 0°C. It is passed into the series reactor. The mother liquor and soda solution are slowly added to the third reactor for neutralization reaction. The generated sodium sulfite suspension is passed through the second and first reactors in turn, and SO 2 An absorption reaction is carried out to generate sodium metabisulfite crystals.

[0004] In the sulfur burning process of the above process, some sulfur particles are small in size, which causes the sulfur to fly over the combustion furnace during air flow transportation, which is not conducive to full combustion. On the one hand, it affects the production capacity, on the other hand, it causes the cooling pipe to be blocked after sulfur burning, and on the third hand, it may affect the product quality. Therefore, it is necessary to develop a sulfur processing equipment to solve the above problems. Utility Model Content
