The protection structure is stable, the material performance is excellent, and the purpose of protection can be well achieved.

Description

technical field [0001] The invention relates to the field of protection and safety, more specifically, to a protection structure for a high-pressure vessel. Background technique [0002] At present, in the process of air tightness and functional test, two gas cylinder groups (3 gas cylinders in each group, each gas cylinder filled with 35MPa compressed air) are used as the gas source. The product is filled with 30MPa compressed air, and about 1MPa compressed air will be ejected from the product nozzle during the function test. [0003] According to the "Stationary Pressure Vessel Safety Technology Supervision Regulations" (TSG21-2016), according to the classification standard of working pressure, the pressure greater than 10MPa is high pressure, according to the classification standard of danger and hazard, the pressure vessel is a third-class pressure vessel, which belongs to the hazard The highest level of sex and danger. In the industrial sector, high-pressure container...

Problems solved by technology

[0004] At present, the test work is carried out in the factory building. Due to the limitation of the site conditions, it is impossible to isolate the operators from the product and the high-pressure gas cylinder group on site.

During the test, there are mainly three types of safety hazards: one is the damage to personnel and equipment caused by the accidental disengagement of the stainless steel high-pressure corrugated pipeline. The air pressure in the inflation pipeline can be as high as 30MPa. If the reliable connection causes disengagement, the connecting pipeline will swing violently and freely under the action of high-pressure gas, which is very easy to cause injury to the on-site personnel; the second is the personal injury caused by the gas leakage and high-speed ejection caused by the accidental disconnection of the pipeline, and the internal storage of the product The air tank stores compressed air with a pressure of up to 30MPa. If the pipeline is accidentally disconnected during the test, the compressed air in the air tank will leak and be sprayed out at a high speed (30MPa pressure difference, the air velocity at the leak can reach up to 707m / s), If there is no corresponding isolation and protection facility, certain injuries will be caused to the on-site personnel; the third is the personnel injury caused by the high-pressure and high-speed compressed air ejected from the nozzle during the equipment function test. During the system function test, the spherical (or ring) cylinder in the product The stored 30MPa compressed air will be ejected from 12 nozzles (1MPa pressure difference, the air velocity at the nozzle can reach up to 435m / s instantaneously). Once the gas is accidentally released when people approach, it will cause serious injury to the personnel on site
