Description

Technical Field

[0001] The utility model relates to the technical field of gas explosion safety protection equipment, in particular to a safety protection suit for liquid oxygen explosion operations. Background Art

[0002] Liquid oxygen (including liquid carbon dioxide) gas explosion operations also have certain safety risks. For example, the liquid oxygen commonly used in our gas explosions can reach a temperature of -183°C under standard atmospheric pressure. Improper operation may cause severe frostbite or even endanger life. The liquid storage equipment Dewar tank used in gas explosion operations usually has an operating pressure of 32.3MPa or 2.4MPa. The gas explosion pipeline network is complex. If cold gas or cold liquid flows out due to sudden pressure release, it may easily cause injury to personnel.

[0003] Oxygen is a strong oxidant that can accelerate combustion and react strongly with many substances. When it is close to or hit by acids, alkalis, grease, flammable and explosive items, high-temperature heat sources, or electric sparks, it is more likely to cause combustion or even explosion accidents. In addition, in the current liquid oxygen explosion operation, liquid oxygen is filled from the liquid storage tank into each blast hole fracturing device. The whole process is complicated, with many steps and high safety risks. It is necessary to attach great importance to the safety protection of on-site workers while continuously increasing the standardized operation of liquid oxygen explosion. However, there is currently a lack of special safety protection clothing that is truly suitable for liquid oxygen explosion operations. Utility Model Content
