Abstract
The invention discloses a floating roof storage tank charge transfer device, which comprises a conducting metal plate and a spring type pressure support frame, wherein the spring type pressure support frame is integrally formed into a Z shape through an upper part support frame, a middle support frame and a bottom support frame, a spring is arranged on the upper part support frame of the spring type pressure support frame, the tail end of the upper part support frame is connected with a pressure element, the pressure element is propped and pressed on the conducting metal plate, and the bottom support frame of the spring type pressure support frame is fixedly connected with the conducting metal plate through a screw nut. The pressure element presses the conducting metal plate onto a tank wall through the pressure provided by the spring type pressure support frame, and the large-area tight pasting of the conducting metal plate and the tank wall is realized. The floating roof storage tank charge transfer device has the advantages that the spark discharge probability in the conducting sheet lightning current discharge process can be reduced, the storage tank lightning stroke fire hazard accident caused by the existing conducting sheet is reduced and eliminated, and the lightning-stroke-resistant safe operation of a storage tank can be guaranteed.
Description
technical field [0001] The invention relates to a charge transfer device for a floating roof storage tank. Background technique [0002] Petroleum is an important strategic material, which is related to the development of the national economy and the stability of the society. At present, the country has established a number of large-scale national oil reserve bases, and oil reserves mainly use large floating roof storage tanks for crude oil storage. At present, in the storage tank design, a conductive sheet is usually installed every 3m along the secondary seal of the floating roof storage tank to discharge the electrostatic charge and lightning current. In recent years, there have been many fire accidents of floating roof storage tanks caused by lightning strikes in crude oil depots in China. Through accident investigation and analysis, it is believed that the current conductive sheet is easy to cause lightning sparks and cause storage tank fire accidents. SUMMARY OF THE...
