Description

Technical Field

[0001] The utility model relates to the technical field of aminosulfonic acid production, in particular to aminosulfonic acid rapid drying equipment. Background Art

[0002] Aminosulfonic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. It is generally white, odorless, rhombic flaky crystals and is soluble in water and liquid ammonia. At room temperature, as long as it is kept dry and not in contact with water, solid aminosulfonic acid does not absorb moisture and is relatively stable. The aqueous solution of aminosulfonic acid has the same strong acidity as hydrochloric acid, sulfuric acid, etc. In the production of aminosulfonic acid, drying equipment is used for drying operations.

[0003] A Chinese patent discloses a boiling drying tower drying equipment for aminosulfonic acid (authorization announcement number CN217979704U). The patented technology can flip the aminosulfonic acid on the surface of the disc by setting a rotating unit, so that the aminosulfonic acid at the bottom can be flipped to the top for drying, so that the drying effect is more sufficient and the drying efficiency is improved. However, the above-mentioned drying equipment performs the drying operation of aminosulfonic acid by heating and stirring. There is a problem of easy burning in the dead corner of stirring, which is not conducive to the preparation quality of aminosulfonic acid.
