Description
Technical field
The utility model relates to a kind of floating roof tank guide post electric insulation and sealing devices.
Background technique
With the development of world economy, petroleum consumption rapid development, various countries' crude stockpile based on large floating roof oil tank,
Since floating plate area is big, thunder disaster obviously increases large floating roof oil tank.So far from 1972, domestic that biggish oil tank occurs altogether
Lightning stroke Fire explosion accident nearly 30, causes huge economic loss.When storage tank is by direct lightning strike or inductive lightning, floating plate with
It can produce biggish potential difference between tank skin, it is easy to cause flashing between floating plate and tank skin to discharge, once herein may be used
Gas concentration reaches explosion limit, will certainly cause storage tank fire blast accident.In recent years, the country had recurred several petroleum
Storage tank fire blast accident due to caused by the incendiary sources such as lightning stroke, electrostatic.
Storage tank floating plate drifts about in the process of running in order to prevent, and floating roof tank is all provided with guide pipe, guide pipe
Effect there are two main, one is the amount of progress oil and sampling, and not outer one most important acts on is to carry out positioning and guiding to floating plate.
Friction generates spark in floating plate lifting process in order to prevent, and guiding wheel seat and copper directive wheel, but storage tank are mounted on floating plate
In the process of running, since floating plate drifts about, certain gap will necessarily be generated before guide pipe and directive wheel.Oil product, which belongs to bad, leads
Body, oil product can gather a large amount of electrostatic charge on pasta, these electrostatic charges are transmitted on floating plate such as cannot be immediately into and out of when flowing
It eliminates, potential difference, Yi Yinqi electrostatic spark electric discharge phenomena will be generated between floating plate and guide pipe；On the other hand, storage tank is meeting with
When being struck by lightning, there are discharging gap between guide pipe and metal floating plate, meeting moment when lightning stroke between the two forms high electricity
Potential difference, Yi Yinqi Spark Discharges occur, thus the fuel gas for surrounding of igniting.Therefore, guide pipe and floating plate is unreliable
Connection is one of incendiary source of petroleum storage tank, once flammable gas concentration reaches explosion limit herein, will certainly cause storage tank fire
Blast accident.
