[0003] With the development of industry, as a key equipment for storing compressed air, gas storage tanks have been widely used in various industries. As a common industrial equipment, the supporting gas storage tank of multifunctional crown block plays an important role in improving work efficiency and ensuring operation safety. However, the existing gas storage tank design has certain safety hazards. Specifically, due to the water contained in the compressed air during long-term use, rust appears on the inner wall of the gas storage tank, forming iron filings. When the internal pressure of the gas storage tank is too high, these iron filings may be discharged together with the compressed air from the exhaust port located in the upper part of the gas storage tank in the horizontal direction. Due to the high-speed airflow during the exhaust process, iron filings and other particulate matter may be carried, causing pollution to the surrounding environment, and if personnel pass by the exhaust port at this time, they may be injured by the flying iron filings, posing a safety hazard.

[0004] In addition, the discharge of iron filings and other particulate matter not only affects the safety of the working environment, but also may cause damage or failure of related equipment, increasing maintenance costs and downtime. Therefore, the traditional gas storage tank lacks an effective filtering structure to capture these iron filings to reduce the risk of their being discharged to the outside.

[0005] Therefore, it is necessary to study a gas storage tank that effectively prevents iron filings and other particles from being discharged with gas to threaten personnel safety, normal operation of equipment and working environment, and improves overall safety. UTILITY MODEL CONTENTS
