if combustible and explosive media such as diesel oil are mixed in the oil mist, the flash point of the media can be reduced, the upper limit and the lower limit of explosion can be shortened, and explosion can be generated.
Most of the existing static oil-gas separators adopt a glass fiber folding cylinder type filter element as an oil mist separation element. The oil mist is coalesced into large-particle oil drops little by little in the process of passing through the glass fiber layer and falls back under the action of gravity. In the practical application process, along with equipment operation condition improves, oil gas volume increase still has partial oil gas loss, simultaneously, needs regularly change the filter core, produces certain later maintenance cost.
Aiming at the oil stain separation effect of the current common static oil-gas separator, a more efficient oil-gas separator is needed under the condition of ensuring that the arrangement space is not changed
In conclusion, in order to solve the problem, a novel static oil-gas separator is designed.
