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...
