Description
Technical field
The present invention relates to a kind of combustible and explosive areas static erasers such as petrochemical industry Oil & Gas Storage, in particular to a kind of
The pipeline oil product Xelminator of intrinsic safety type.
Background technique
In petrochemical enterprise oil product transmission process, because oil product conductivity is low, oil transportation excessive velocities, oil product contain impurity
Etc. reasons, will lead to and generate a large amount of electrostatic in oil product transmission process, electrostatic can bring security risk." prevent electrostatic accident general
Directive/guide " (GB 12158-2006) and " liquid petroleum product electrostatic safety regulation " (GB 13348-2009) clear stipulaties can be in pipe
Road end installing liquid electrostatic arrester is for reducing electrostatic accumulation.But passive Xelminator makes to discharge by way of induction
Needle static discharge eliminates electrostatic charge of oil, can not completely eliminate the electrostatic in oil product, needs that a kind of to completely eliminate oil product quiet
The equipment of electricity, the invention exactly propose in this context.
The method for eliminating the electrostatic in pipeline oil product at present mainly has: (1) metal shell earth leakage electrostatic, this kind of mode
Electrostatic on metal shell can only be guided, the electrostatic in oil product cannot guide, and static elimination needs the regular hour cannot
Meet oil product flow rate requirement, so remaining difficult to avoid the generation for the accident of sparking in this way.(2) Line Static arrester is installed additional,
In Chinese invention patent, the means for eliminating static electricity in combustible liquid pipeline and notification number that notification number is CN2585526Y are
The pipe type static eliminator of CN2849430Y is one isolated pipe of placement in metal shell.The former is by multiple collection
Banish that acusector is longitudinally multiple rows of to be circumferentially evenly distributed on metal shell, and pass through in insulation tube wall insertion insulation tube, by with
The needle point that ground is connected discharges charge to neutralize the electrostatic in oil product.Although this device can eliminate the electrostatic of needle point close front
Lotus, but due to using isolated pipe, oil product is when flowing through and the friction of tube wall is more prone to produce electrostatic, while the oil in pipeline
After product impact leads to tip wear, electric eliminating effect sharply declines, and can aggravate the generation of electrostatic to a certain extent.The latter is will be more
A electric eliminating needle is mounted on metal shell, and pass through insulation tube wall insertion insulation tube in, the principle of electric eliminating be also by with ground
Connected needle point discharges charge to neutralize the electrostatic in oil product.Although this device can also eliminate the electrostatic of needle point close front
Lotus, but the electrostatic between needle point and conduit cannot effectively eliminate, and the friction of exactly this part oil product and isolated pipe can add
The generation of acute electrostatic, at the same there is also oil product impact leads to tip wear in pipeline after, the problem of electric eliminating effect sharply declines.Cause
This, existing static eraser cannot effectively eliminate the electrostatic charge of transporting oil in pipeline mostly.In addition electric eliminating is being used
In needle and when the process of charge, since spray point discharge voltage is excessive sometimes, the connection between spray point and pipeline is caused punch through,
Cause pipe wear serious and uncertain discharge capacity size leads to power supply waste and discharge voltage is excessive leads to oil product charge
The case where amount overload leads to peril.
Summary of the invention
To solve to generate a large amount of electrostatic bring security risks in oil product transportational process, more thoroughly eliminate quiet in oil product
Electricity avoids oil product charge from overloading, and the present invention provides a kind of pipeline oil product Xelminators of intrinsic safety type, and technical solution is such as
