Abstract

The invention relates to the technical field of sodium metabisulfite, and discloses a reaction kettle for preparing sodium pyrosulfite. The reaction kettle comprises a reaction kettle body, wherein a bottom plate is fixedly connected to the bottom of the reaction kettle body, a screw pipe is fixedly connected to the bottom of the bottom plate, a connecting rod is fixedly connected to the bottom of the reaction kettle body, one end of the connecting rod is fixedly connected with a universal wheel, and the top of the reaction kettle body is fixedly connected with a motor. The reaction kettle for preparing sodium metabisulfite achieves the purpose of good mixing effect, solves the problem of poor mixing effect of a common reaction kettle for preparing sodium metabisulfite, enables the reaction kettle body to play a very good stirring effect on sodium metabisulfite, avoids the situation of poor mixing effect, can realize full stirring of sodium pyrosulfite in the reaction kettle so as to improve the preparation effect of sodium pyrosulfite, is convenient to use, increased in mixing speed and improved in working efficiency, and further meets use requirements.

Description

technical field [0001] The invention relates to the technical field of sodium pyrosulfite, in particular to a reaction kettle for preparing sodium pyrosulfite. Background technique [0002] Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong SO2 smell, and the specific gravity is 1:4. It is soluble in water, and the aqueous solution is acidic. When in contact with strong acid, SO2 is released to form corresponding salts. It can be stored in the air for a long time. It is oxidized to Na2S2O6, so the product cannot be stored for a long time. When it is higher than 150 degrees Celsius, it will decompose SO2, which is used for the production of hydrosulfite, sulfamethazine, caprolactam, etc., as well as the purification of chloroform, phenylpropyl sulfone and benzaldehyde , the photographic industry is used as a fixing agent ingredient, the fragrance industry is used to produce vanillin, it is used as a preservative in the brewing industry...
