Description

Technical Field

[0001] The utility model relates to the technical field of air separation cryogenic towers, in particular to an impure liquid discharge mechanism in an air separation cryogenic tower. Background Art

[0002] Air separation low temperature is also called low temperature distillation tower. The low temperature distillation tower is a tower that performs distillation process at low temperature to separate liquid air into components such as oxygen and nitrogen.

[0003] Once the air separation low temperature tower is used and the production is abnormal, resulting in unqualified liquid, a large amount of liquid with substandard purity will enter the liquid storage tank, causing the purity of the storage tank to be destroyed, leading to quality accidents. At present, the liquid discharge on the air separation distillation tower is mostly discharged by manual valves and single pipelines. The team members have been dealing with it for a long time, which is very easy to cause purity damage accidents. In addition, the direct discharge of impure liquid is easy to cause waste, so it needs to be improved. Utility Model Content

By embedding and fixing the end of the connecting pipe 2 away from the connecting pipe 1 on the discharge pipe 1 and the discharge pipe 2, the impure liquid discharged from the discharge pipe 1 and the discharge pipe 2 can be discharged into the storage tank through the connecting pipe 2 and the connecting pipe 1.

[0013] Preferably, a connection block is welded to the bottom end surface of the storage tank, and the bottom end surface of the connection block is welded to the installation panel.
