Problems solved by technology

The floating disc is assembled in the tank, and the overall sealing performance of the assembled floating disc and seal cannot be confirmed by this method
[0006] The light transmission test is to use light beams to irradiate the surface of the floating plate from the upper and lower parts of the floating plate, or to irradiate the leak-prone parts such as the tank wall and the edge seal of the floating plate with the light beam, and observe whether there is light passing through. If there is light, it means that the sealing not good
The seal of the floating plate is usually sealed with a bladder-type tongue-type or elastic tongue-type scraper and other structures that are in close contact with the tank wall to achieve two seals. After the floating plate is assembled, the leaking parts that are prone to occur include the floating plate accessories (manhole, Breathing valve, support column), guide column, edge seal and splicing seam of the floating tank, when testing these parts, due to the limited scattering of the light beam, the light transmission test cannot guarantee that the test results fully meet the requirements

Embodiment Construction

[0021] The technical scheme of this patent is further described in detail in conjunction with the accompanying drawings and the fully liquid-contacted high-efficiency sealed honeycomb floating plate as an example.

[0022] The storage tank 1 size is 18 meters in diameter in the described embodiment, and the capacity is 3500 cubic meters. The storage tank 1 is a gasoline tank. The specific detection steps are as follows:

[0023] (1) Preparation before testing:

[0024] a. Transport the nitrogen tank 2 for testing into the storage tank 1 from the lower manhole 3 of the storage tank, and place it in the middle of the bottom of the storage tank 1 below the center of the floating plate 12. Open the storage tank upper manhole 4 and all ventilating ports on the tank top, close the storage tank inlet and outlet oil pipeline 9 valves, close the storage tank lower manhole 3 and the oil measuring hole 17.

[0025] b. Selected detection parts: floating disc breathing valve 18, floating...

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...
