Problems solved by technology

[0003] The safety risk analysis of atmospheric storage tanks is mainly to prevent leakage, cracking and foundation subsidence of atmospheric storage tanks. Most of the existing technologies use manual analysis and control based on industry control plan data. However, when atmospheric pressure After the storage tank has been used for a long time or has been repaired many times, there will be certain errors in the safety risk analysis according to the industry's control plan data, which directly leads to the failure of the safety risk analysis results of the atmospheric pressure storage tank. It cannot be effectively controlled for atmospheric storage tanks. Therefore, we propose a method for safety risk analysis of cryogenic liquid double-layer atmospheric storage tanks

Abstract

The invention discloses a method for safety risk analysis of a cryogenic liquid double-layer atmospheric storage tank. The method comprises the following steps: s1, collecting data and establishing a database; s2, performing three-dimensional modeling, namely performing three-dimensional modeling through a three-dimensional simulation server in combination with the acquired data; s3, performing a simulation experiment; s4, carrying out risk assessment on chemicals stored in the double-layer atmospheric storage tank, and carrying out a load simulation experiment in combination with the three-dimensional modeling model; s5, sorting the no-load simulation experiment in the step S3 and the two load simulation experiments in the step S4, transmitting data into a database for independent storage, and feeding back a result to terminal personnel. According to the invention, the safety risk analysis is carried out on the double-layer atmospheric storage tank by adopting the three-dimensional modeling and simulation experiment modes, so that the safety risk analysis and detection are more accurate compared with the existing mode that analysis and management and control are carried out manually according to control plan data of the industry.

Description

technical field [0001] The invention relates to the technical field of safety risk analysis of double-layer atmospheric storage tanks, in particular to a method for safety risk analysis of cryogenic liquid double-layer atmospheric storage tanks. Background technique [0002] Atmospheric pressure storage tanks refer to steel welded storage tanks with a design pressure of less than 0.1MPa, built on the ground, and storing non-artificially refrigerated, non-toxic petroleum, chemical and other liquid media. [0003] The safety risk analysis of atmospheric storage tanks is mainly to prevent leakage, cracking and foundation subsidence of atmospheric storage tanks. Most of the existing technologies use manual analysis and control based on industry control plan data. However, when atmospheric pressure After the storage tank has been used for a long time or has been repaired many times, there will be certain errors in the safety risk analysis according to the industry's control plan ...
