Emergency measures for carbon dioxide storage tanks
Date: Apr 03, 2020
Cryogenic storage tank: cryogenic liquid carbon dioxide storage tank adopts "combined, safety system valve" and uses two sets of safety valves to work at the same time. When the safety valve is 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 safety accessories of cryogenic storage tanks should be checked regularly. General pressure gauges, level gauges, safety valves, and sheet devices are checked or replaced once a year. When the pressure in the tank exceeds 1.6kg, the gaseous oxygen is released from the pressure control valve to ensure that the pressure in the tank is constant and safe. The inspection of the pressure gauge mainly checks whether the measuring range meets the requirements and whether the form is a 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 boost pressure regulating valve RPE. When the boost pressure regulating valve is adjusted, it is performed when the tank is full.
Booster valve, a booster valve at the gas outlet of the booster. The connection method is: a pipe is connected by the liquid inlet pipe or the liquid outlet pipe, connected to an external supercharger, and then the above components are connected in sequence, and then the outlet pipe after the safety valve, also called the return pipe, is connected. Go to the vent tube of the storage tank so that the problem of insufficient pressure can be solved.
When a new load of liquid is added to the carbon dioxide storage tank, check whether the pressure is normal. When the cryogenic liquid pump is in operation, determine whether there is an ice barrier inside the storage tank. After the liquid in the tank is used up, the pressure is evacuated, and the interior must not be blown with air. Due to the large moisture content of the air, it will remain inside the storage tank and condense into ice.
Warmly remind the storage tank to perform gas replacement treatment before the first use, and use nitrogen to purge and replace the air in the pipeline and the storage tank.
