Issues regarding the design of storage tanks
Thread Content
I have seen some large storage tanks designed with sloped bottoms that facilitate drainage (tilted toward the outlet pipe), and the foundations are also made at an appropriate slope. I wonder what size of storage tanks require such a design, and where can I find the relevant regulations? I need to design systems with a capacity of 1000 m3/500 m3. Do I need to install foam fire nozzles for both Class A and Class B media?
You are referring to tanks with an inclined bottom that slopes toward the outlet, at a slope of 1.5–2%. This design is commonly used for large storage tanks
Sloped-bottom tanks, with a slope leading toward the outlet and a gradient of 1.5–2%; this design is commonly used for large storage tanks. ——Have you thought about the advantages and disadvantages of this design? If the slope faces the exit, the water cut will not reach the pooled water ； If the slope faces the water cut-off, sediment accumulates at the cut-off, leading to blockages and corrosion.
Reply to 1# wxlh66: It can be made flat, and by installing a dirt collection tray, the problem on the second floor can be solved.
In my opinion, the slope design at the bottom of a storage tank is primarily determined by the foundation beneath it; if it is a soft foundation, a slope is generally required, mainly to account for foundation settlement. Installation of fire foam nozzles: For water-insoluble flammable and explosive substances, foam nozzles must be installed if the volume is greater than 200 cubic meters ； It is also necessary to do this for flammable media that are soluble in water and have a volume of more than 500 cubic liters.
