AI Technical Summary
Existing water-sealed wells in crude oil tank farms occupy a large area and have a long construction period, which cannot effectively solve the problem of fire spread in oil spills, combustion, and explosion accidents.
The first and second well bodies are set up side by side in the main drainage ditch. The outlet ends of the first and second drainage pipes are designed to be inserted into their respective well bodies. Combined with structures such as slopes, filter plates and grid plates, water seal and explosion-proof functions are achieved.
It reduced the area occupied by the crude oil tank area drainage system, shortened the construction period, and effectively prevented the spread of fire and pollution in the event of a fire and explosion, thus preventing secondary disasters.
