Description

Technical Field

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

[0002] Chlorobenzene is an important organic solvent and reaction intermediate. It is highly volatile at room temperature, and its release into the air poses a threat to human health and pollutes the environment. The volatilization of chlorobenzene also leads to waste in enterprise production and increases production costs. Furthermore, chlorobenzene is a flammable, explosive, and volatile organic liquid that easily generates a mixed gas in the air. If it comes into contact with an open flame, it can explode, causing significant harm to people and society. In existing devices, the water in the chlorobenzene vapor condenser is not flowing, resulting in poor cooling of the chlorobenzene vapor and thus reducing the chlorobenzene recovery efficiency. Therefore, we propose a chlorobenzene recovery device for nitrochlorobenzene production. Utility Model Content
