Problems solved by technology

At present, there have been many researches on the problem of static electricity derivation of floating roof oil tanks, most of which are to conduct current from the outside, such as: changing the structural layout of the static conductive sheet, adding jumper wires, etc. These methods will have certain effects, but Static electricity cannot be evenly exported, and the major hidden dangers of explosion accidents caused by lightning strikes have not been completely resolved
Another suggestion is to cancel the static conductive sheet to solve the problem of lightning sparks, but this reduces a way for static electricity to be exported, and needs to be effectively replaced by other methods

Embodiment

[0017] A device for discharging static electricity through a soft seal for a floating roof oil tank, comprising a wrapping tape 1 , a soft seal bag 2 and a filling liquid 3 . The soft seal bag 2 is fixed between the bottom platen 6 and the top platen 7 through the tape 1, and the tape 1 is fixed on the floating roof 8, and the floating roof 8 is provided with a floating roof surface 5; the other side of the tape 1 is connected to the tank Wall 4 is in contact. The tape 1 and the soft seal bag 2 are made of static conductive and flame retardant materials, and the filling liquid 3 is added with antistatic additives.

[0018] The soft seal bag can be made of static conductive and flame retardant rubber materials, such as nitrile rubber containing polyvinyl chloride, so that it has excellent oil resistance, aging resistance, and wear resistance. By adding static conductive and flame retardant materials, the rubber has static conductive properties. Flame retardant performance, its...

Abstract

The invention relates to a device for guiding out static electricity of a floating-roof oil tank through a soft seal. The device comprises a wrapping tape, a soft sealed packet and filling liquid, wherein the soft sealed packet is fixed between a bottom pressing plate and a top pressing plate through the wrapping tape, and the wrapping tape is fixed to a floating roof which is provided with a floating roof surface; the other side of the wrapping tape makes contact with the tank wall. The probability that because spark discharge happens to a conductive plate and the tank wall during a lightning strike, a blast accidents is caused is eliminated, and the floating-roof oil tank is protected against electrostatic and lightning strike blast accidents.

Description

technical field [0001] The invention belongs to the technical field of safety of floating roof oil tanks, and relates to a device, in particular to a device for deriving static electricity from a floating roof oil tank through a soft seal. Background technique [0002] Static electricity will be generated during the process of oil intake, oil output and blending of the oil tank. Under certain conditions, discharge will cause explosion accidents, so the generated static electricity needs to be exported in time. At present, there are two main ways to export static electricity from floating roof oil tanks: one is through the jumper wire between the floating plate and the tank wall, and the other is the static conductive sheet at the sealing part. However, with the development of large-scale oil tanks, the problems of this static electricity export method have been exposed: large-scale oil tanks are more susceptible to lightning strikes, and there have been many lightning strike...
