Safety environmental protection buried oil tank

Abstract

The present invention provides a safe and environmental protection type underground oil tank which has a tank body of two-layer structure composed of an inner tank wall and an outer tank wall; an interlayer formed between the inner tank wall and the outer tank wall; the separating explosion-proof materials respectively filled in the cavity of tank body and the interlayer formed between the two-layer tank walls; an oil leak detection device provided in the interlayer between the two-layer tank walls; as well as an oil spill pool established on the manhole cover of the tank body, the bottom of the oil spill pool being connected with the interlayer between the two-layer tank walls. Since the separating explosion-proof materials are provided in the oil tank, it is possible to prevent the accidental combustion and explosion accidents initiated by naked fire, static electricity, welding, gunshot, collision and misoperation, and thus ensure the intrinsic safety of oil tank. With the double walled tank structure, the oil tank may effectively overcome the leakage and/or leak of oil and gas and thus avoid serious damages to the soil around the gasoline filling station and destruction of underground water resources. At the same time, an oil leak detection device is provided in the cavity of the double walled tank, so that it is possible to detect the volatilization of oil and gas in time and thus make repairing welding the tank wall in case of charged oil. An oil spill pool is provided on the manhole of the tank body, so that it is possible to prevent such phenomena as oil spill and ebullition in the process of the oil filling and to adopt the countermeasures in time upon detection of such phenomena.
