Description

Technical Field

[0001] The utility model relates to a chimney device, in particular to a cold box gas discharge chimney and a cold box, belonging to the technical field of cold box equipment. Background Art

[0002] During the operation of the cold box, process gas leakage may occur due to equipment aging, poor sealing, etc. These leaked gases are usually toxic, corrosive or flammable and explosive, such as carbon monoxide and hydrogen, which pose serious safety hazards to the internal environment of the cold box and the health of operators. Although the local ventilation device in the prior art can dilute the leaked gas by ventilation, it can only dilute the gas within a limited range, and it is difficult to achieve effective control of the internal environment of the entire cold box. Conventional chimney devices usually adopt a single cylinder structure. Since the gas leakage inside the cold box is usually accompanied by temperature and pressure fluctuations, the structural strength of conventional chimney devices is difficult to withstand dynamic loads, and fatigue fracture problems may occur after long-term use. In addition, conventional chimney devices are usually straight-cylinder structures, lack of guidance for airflow, and turbulence and reflux are prone to occur in the gas during the rising process, which increases the emission resistance.
