Abstract

The invention relates to a fully-sealed volatilization prevention device for an emergency drainage pipe of a floating roof and a method. The device and the method mainly solve the problem of water seal volatilization in the prior art. The fully-sealed volatilization prevention device for the emergency drainage pipe of the floating roof comprises a floating ball, a connecting rod, a cover plate, aconnector, a pin, a support, an emergency drainage port, the emergency drainage pipe, a fixing bolt, a zipper, a filter screen, a floating roof upper surface, a bolt gasket, a cover plate sealing gasket and sealing rings. The device is arranged above the emergency drainage pipe of the floating roof of an outer floating roof storage tank and is used for preventing volatilization of a water seal medium in the emergency drainage pipe and oil in the tank, by means of the technical scheme, the problem is well solved, and the device can be used for emergency drainage of the floating roof of the outer floating roof storage tank.

Description

Technical field [0001] The invention relates to a fully-sealed floating roof emergency drainage pipe volatilization device and method, belonging to the technical field of oil and gas storage and transportation, and specifically relates to an emergency drainage technology for the floating roof of an outer floating roof storage tank. Background technique [0002] The emergency drainage device is a safety device on the floating roof of the outer floating roof storage tank. Its function is to prevent the excessively thick water from causing the floating roof when heavy rain occurs and the central drainage pipe of the floating roof is too late to drain the water on the floating roof. Tilting or sinking the pan, by setting an emergency drain, the accumulated water after a certain height is directly discharged into the storage tank through the emergency drain. Although this method caused the rainwater to mix with the stored oil, it avoided the danger of sinking or instability of the flo...
