Embodiment
[0017] A charge transfer device for a floating roof storage tank through corona discharge, which includes metal bristles, a metal brush body, a metal connecting piece, and a fixing bolt. The metal bristles 1, the metal brush body 2, the arc section 3, and the horizontal section 4, the metal brush body 2, the arc section 3, and the horizontal section 4 are integrally formed, the metal bristles 1 are closely attached to the tank wall 5, and the metal bristles 1 are fixed On the metal brush body 2, the arc segment 3 relies on its own elastic force to make the metal bristles 1 come into strong contact with the tank wall 5. The metal arc section 3 is connected to the horizontal section 4, and the horizontal section 4 is fixed on the secondary sealing rubber ring by fixing bolts.
[0018] In the above embodiment, the length of the metal bristles is 1 cm-10 cm, and the metal bristles, the metal brush body, the metal connecting piece, and the fixing bolt are all made of corrosion-resista...

The invention relates to an electric charge transferring device for a floating roof storage tank through corona discharge. The electric charge transferring device comprises metal brush hair, a metal brush body and a metal connecting slice. The metal brush hair is fixedly arranged on the metal brush body. The metal connecting slice comprises a circular arc section and a horizontal section which are connected sequentially. The metal brush body is connected with the circular arc section of the metal connecting slice. The metal brush hair makes contact with the tank wall in a closely attached mode through the elastic force of the circular arc section. The horizontal section is fixed to a secondary seal rubber ring. According to the electric charge transferring device, the metal brush hair is made to contact the tank wall of the floating roof storage tank through the elasticity of the electric charge transferring device; the corona discharge is achieved; the generation of sparks is avoided; the safe discharge of static electricity of oil products can be achieved without an external auxiliary installation mechanism; the probability of spark discharge of a conducting plate in the lightning current discharge process can further be reduced; lightning stroke fire accidents of the storage tank due to an existing conducting plate are reduced and eliminated; the safe operation of lightning stroke resistance and static electricity resistance of the storage tank is ensured; the problem of discharge of static electricity charge and the lightning current is solved; the fire accidents of the storage tank are avoided.
Description
Technical field [0001] The invention belongs to the technical field of storage tanks, and relates to a floating roof storage tank charge transfer device through corona discharge. Background technique [0002] Petroleum is an important strategic material, 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 the existing oil reserves mainly use large floating-roof storage tanks for crude oil storage. In the storage tank design of the prior art, a conductive sheet is usually installed every 3m along the secondary seal of the floating roof storage tank to discharge electrostatic charges and lightning current. In recent years, there have been a number of floating roof storage tank fire accidents caused by lightning strikes in crude oil storage in China. Through accident investigation and analysis, it is believed that the current conductive sheet is easy to c...
