Emergency treatment measures for cryogenic storage tanks
Date: May 25, 2020
Cryogenic storage tank: The cryogenic liquid storage tank adopts "combination and safety system valves" to use two sets of safety valves to work at the same time. When the safety valves are regularly checked, one side can be closed and the other side can continue to work to ensure the safe operation of the storage tank.
The cryogenic storage tank safety accessories should be checked regularly, and the general pressure gauge, liquid level gauge, safety valve, film device, etc. should be verified or replaced once a year. When the pressure in the tank exceeds 1.6kg, the gaseous oxygen will be discharged from the pressure control valve to ensure that the pressure in the tank remains unchanged and safe. The inspection of the pressure gauge mainly checks whether the range meets the requirements and whether the form is diaphragm type. Therefore, there must be deflation pipes and valves. The working pressure of the storage tank is adjusted. The pressure in the storage tank is adjusted by adjusting the pressure-increasing regulator valve RPE. The pressure-increasing regulator valve is adjusted when the tank is full.
Booster valve, a booster valve at the gas outlet of the booster. The connection method is: connect a pipe from the inlet pipe or the outlet pipe, connect to the external supercharger, and then connect the above components in turn, and then the outlet pipe of the safety valve, also called the return pipe, is connected to Above the emptying tube of the storage tank, this can deal with the problem of insufficient pressure.
When a new liquid is added to the carbon dioxide storage tank, see if the pressure is sufficient. When the cryogenic liquid pump is in operation, is it normal? Determine whether there is ice separation inside the storage tank. After using the liquid, empty the tank and evacuate the pressure. Do not use air to purge the interior. Because the water content of the air is large, it will remain inside the storage tank and condense into ice.
Warm reminder: Before the first use of the storage tank, it is necessary to perform gas replacement treatment, and use nitrogen to purge the air in the replacement pipe and the storage tank.
