Abstract

The invention discloses a method for detecting the sealing performance of a floating plate in a storage tank, and relates to the field of detection of the sealing of a storage tank. The detection method includes the following three steps: (1) preparation before detection; (2) deflation detection; (3) data analysis and processing. The beneficial effects of the present invention are: (1) the overall airtightness of the floating disc in the storage tank can be detected, and before the storage tank is put into use, this method is used to detect the airtight effect of the floating disc in the storage tank; (2) nitrogen is used as the The detection medium will neither pollute the environment nor cause harm to the health of the inspectors; (3) The detection method is relatively simple, practical and convenient, just use a nitrogen detector to detect each measuring point, and record the data for comparative analysis , you can judge whether there is a leak at the measuring point.

Description

technical field

[0001] The invention relates to the field of detection of the inner seal of a storage tank, in particular to a method for detecting the sealing performance of a floating plate in a highly efficient seal of a storage tank. Background technique

[0002] In the petrochemical industry, leakage generally exists in all links of production, processing, storage, transportation and even sales. Most materials are flammable, explosive or poisonous and harmful. Once a fire occurs due to leakage, the consequences are often very serious, and at the same time it will cause serious pollution to the environment and bring significant economic losses to the enterprise.

[0003] In recent years, with the country's emphasis on environmental protection, the country promulgated a new VOCs emission implementation standard in 2015, which raised the VOCs emission standard requirements. The "GB 31570-2015 Petroleum Refining Industry Pollutant Discharge Standard" and "GB 31571-2015 Pet...
