Description

Technical Field

[0001] This utility model relates to the field of acetone recovery technology, specifically to a drying device for acetone recovery. Background Technology

[0002] Acetone is a colorless, transparent liquid that is volatile and flammable. It is widely used in the chemical, pharmaceutical, and paint industries, often as a solvent to dissolve and dilute substances insoluble in water. However, its volatility means that a large amount of acetone is released into the air during use, resulting in resource waste and potential environmental pollution.

[0003] When acetone is used industrially, it contains some water. If the used acetone is not utilized, it will easily cause acetone to be released, resulting in environmental pollution and waste of resources. When acetone is recycled using silica gel particles, the silica gel particles will lose their ability to absorb moisture due to long-term use. The silica gel particles need to be removed from the device and regenerated using dry gas. The regeneration of silica gel particles is inconvenient, and the single regeneration method has low regeneration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for acetone recovery, which has the advantages of facilitating the removal of moisture from acetone and conveniently regenerating silica gel particles, thereby improving regeneration efficiency. This invention solves the problems of silica gel particles having reduced moisture adsorption capacity due to long-term use, requiring the silica gel particles to be removed from the device and regenerated using drying gas, which is inconvenient and results in low regeneration efficiency due to a single regeneration method.
