Honeycomb floating tray system for cylinder storage tank

Abstract

The invention provides a honeycomb floating tray system for a cylinder storage tank. The honeycomb floating tray system for the cylinder storage tank comprises a floating tray body and an edge plate sealing mechanism, and the edge plate sealing mechanism is arranged at the peripheral edge of the floating tray body. The edge plate sealing mechanism comprises an edge plate connecting plate, a stainless steel flexible sealing plate, a stainless steel high flexible supporting plate, a first polytetrafluoroethylene fiber membrane plate and a second polytetrafluoroethylene fiber membrane plate. The edge plate connecting plate is fixed to the outer side of an edge plate. The first polytetrafluoroethylene fiber membrane plate is arranged on the outer side of the edge plate connecting plate. According to the honeycomb floating tray system for the cylinder storage tank, due to arrangement of the edge plate sealing mechanism on the edge of the honeycomb floating tray system, the stainless steel flexible sealing plate can cling to the inner wall of the storage tank so as to enable the edge of the inner wall of the storage tank to be fully sealed; no air phase space exists; oil gas volatilization can be reduced greatly; the sealing compensation amount is large; and due to arrangement of the second polytetrafluoroethylene fiber membrane plate, corrosion resistance of the edge plate sealing mechanism can be increased.

Description

technical field [0001] The invention relates to the sealing field of cylindrical storage tanks, in particular to a honeycomb floating disk system for cylindrical storage tanks. Background technique [0002] In the field of petroleum, petrochemical, and chemical storage technology and equipment, in order to reduce the volatilization of the liquid stored in the storage tank, a floating plate should be installed on the surface of the liquid storage in the storage tank to make it rise and fall with the change of the liquid level in the storage tank, and limit the amount of liquid in the storage tank. The stored liquid is in contact with the atmosphere to achieve the purpose of energy saving and emission reduction. [0003] At present, most vertical cylindrical storage tanks in China use buoy-type internal floating roofs, which are combined with surrounding capsule seals. Since the skin on the top of buoy-type floating discs has a space of more than 100mm from the liquid surface,...

AI Technical Summary

Problems solved by technology

[0003] At present, most vertical cylindrical storage tanks in China use buoy-type internal floating roofs, which are combined with surrounding capsule seals. Since the skin on the top of buoy-type floating discs has a space of more than 100mm from the liquid surface, it is impossible to avoid oil and gas volatilization. Unsatisfactory effect and potential safety hazard

[0004] Domestically, steel floating discs are also used on vertical cylindrical storage tanks, commonly known as iron floating tanks. The liquid in the lack of floating tanks does not volatilize in the tank deck, which is firm and safe, but it is heavy, not corrosion-resistant, and difficult to maintain. The cost is high, the maintenance is prone to defects such as environmental pollution, and there is also a hidden danger of leakage in the edge seal
