Liquid argon atmospheric storage tank is an atmospheric bimetallic flat-bottomed storage tank used to store liquid low-temperature argon; it is usually a bimetal structure, and pearlite sand is used to fill the insulating layer in the middle to ensure that the liquid argon in the internal storage tank is in In the low temperature state, the gas is not easy to evaporate.

Configuration parameter

Volume: 200~50000m³

Working pressure: 10Kpa~50Kpa

Insulation method: double-wall powder accumulation insulation.

Basic type: above-ground installation type, high desktop type.

Storage medium

Liquid nitrogen, liquid oxygen, liquid argon, liquid ethane, ethylene, etc.;

Safe discharge system

Inner tank safety pipe:

The storage tank needs to be equipped with a complete safety system. In addition to the manual exhaust valve and automatic exhaust valve used to automatically control the pressure in the tank, two sets of breathing valves must be set and switched through the three-way valve. When the pressure in the tank reaches 24KPa ,

Exhalation valve

When the pressure in the internal air storage tank drops to -0.5KPa, the breathing valve inhales. When working, two sets of breathing valves must be opened to avoid equipment damage, personal injury or even death. Inhalation can only be done as a last resort. Under normal circumstances, as long as the air is supplied through a self-pressurizing system, the maximum air pressure will be too low.

The stainless steel corrugated compensator is used to compensate the temperature difference stress of all the pipes leading from the top of the inner tank, and the corrugated pipe is arranged on the outer tank.

Outer tank safety pipe:

The top of the outer tank needs to be equipped with an emergency pressure relief device (diameter DN250) and an outer tank breathing valve (diameter DN150) to ensure that the interlayer pressure is within a certain range and to ensure the safety of the equipment.
