Background
Gas storage, i.e., "vessels" that store natural gas; by "gas storage" (UGS) we refer generally to Underground reservoirs; the underground gas storage is an artificial gas field or a gas reservoir formed by reinjecting commodity natural gas conveyed by a long-distance pipeline into an underground space, and is generally built near a natural gas user city at the downstream;
for gas storage in a gas storage, the most important is to ensure the purity of gas, and the gas filtering becomes an indispensable flow, and the existing filtering mode is to pass the gas through a filter screen and filter out particulate matters in the gas for storage;
the filtering mode can cause the deformation and even damage of the filter screen due to larger airflow force for high-flow gas, so that particle impurities and gas are easily mixed again, and the cost of filtering and storing is increased.
