Structural features of Self Bunded Diesel Fuel Storage Tank - SUMAC Auto Recycling Equipment Co.,Ltd

①Tank structure
The self-contained cofferdam diesel fuel storage tank adopts a double-wall design, consisting of an inner tank and an outer tank. The inner tank is the core part of diesel storage, usually made of high-quality carbon steel. This type of material has excellent strength and corrosion resistance, can withstand the pressure and chemical erosion caused by long-term storage of diesel, and ensure the safety and stability of diesel storage. The outer tank surrounds the inner tank to form an independent protective layer. Its material is similar to that of the inner tank, and is mainly used to receive the diesel that may leak from the inner tank. There is a certain gap between the inner and outer tanks. This gap is not a simple space, but is carefully designed. Generally, its volume is at least 110% of the volume of the inner tank, so that there is enough space to accommodate the diesel leaked from the inner tank to prevent it from leaking into the surrounding environment.
②Safety protection structure
In order to further improve safety, the storage tank is equipped with multiple safety protection structures. At the top of the tank, there is a breathing valve, which can automatically adjust according to the changes in the pressure in the tank to ensure that the pressure in the tank is maintained within a safe range. When the pressure in the tank increases due to temperature changes, diesel in and out, etc., the breathing valve automatically opens to exhaust air outward; when the pressure decreases, air is sucked in to prevent the tank from being deformed or damaged due to abnormal pressure. At the same time, the tank is also equipped with an anti-overflow device, which monitors the diesel level in the tank in real time through a liquid level sensor. Once the liquid level reaches the preset warning height, the anti-overflow device will start quickly and automatically close the oil inlet pipeline to prevent diesel from overflowing due to excessive filling, effectively preventing safety accidents such as fire and explosion caused by diesel leakage and environmental pollution.
③Connection and auxiliary facilities
In terms of connection, the tank is equipped with multiple interfaces for the entry and exit of diesel and connection with other equipment. The oil inlet and outlet are usually connected by pipes of standard specifications to ensure the sealing and stability of the connection and prevent diesel from leaking during transportation. In addition, a manhole is also equipped to facilitate staff to enter the tank for regular inspection, maintenance and cleaning. The manhole is designed with a sealing cover that can be tightly closed when not in use to ensure the sealing of the tank. At the same time, a liquid level gauge is installed on the outer wall of the tank, which can visually display the liquid level height of the diesel in the tank. The staff can know the oil level in the tank at any time through the liquid level gauge, so as to arrange refueling or oil usage plans in time and realize efficient management of diesel storage.
