Description

Technical Field

[0001] The utility model relates to the technical field of aromatic hydrocarbon solvent production, in particular to a leakage prevention device for aromatic hydrocarbon solvent production. Background Art

[0002] Aromatic solvents are clear, colorless liquids that are toxic. Fire sources should be eliminated near storage points. Prevent liquids from flowing into sewers, water networks or low-lying areas. Isolate people. Avoid inhalation of vapors and contact with human bodies. Cut off the source of harm as much as possible without causing any harm. If the substance enters the network or sewer, or contaminates land or crops, the relevant units must be notified and measures must be taken to minimize its impact on underground waterways.

[0003] Patent No.: CN215084945U, proposes a leakage prevention device for the production of high-boiling point aromatic solvents. The device has a simple structure and is easy to operate. If leakage occurs during the distillation of the aromatic solvent, the air pressure in the covering bag will be too high. At this time, the reading of the pressure gauge will exceed the set value, and the controller will control the buzzer to alarm to remind the staff to replace and repair, reduce the amount of leakage during the distillation of the aromatic solvent, thereby reducing pollution to the environment and improving safety during use.

[0004] However, during the implementation of the device, since the size of the flange is larger than the pipeline, when the circular extrusion balloon is covered on the pipeline, the staff needs to pull the circular extrusion balloon to change the shape and size of the circular extrusion balloon.
