Abstract
The utility model discloses a pipeline type static eliminator, which is used for delivery systems for hydrocarbon liquids such as petroleum, petroleum products, etc. The utility model comprises a petroleum delivery pipe, wherein static eliminating outer pipes are arranged outside the petroleum delivery pipe with intervals, and each static eliminating outer pipe is fixedly supported on the petroleum delivery pipe through supporting flanges positioned on both ends of the static eliminating outer pipe; a static eliminating needle is fixely arranged on each static eliminating outer pipe, and the front end of the static eliminating needle penetrates through the pipe wall of the petroleum delivery pipe and extends into the petroleum delivery pipe. The extension length of extension into the petroleum delivery pipe of the static eliminating needle is 6-12MM. The outlet side of the static eliminator is provided with a static monitor which can monitor working conditions of the static eliminator at any time. The static eliminator has the advantages of simple structure and convenient operation, can effectively eliminate static charge in delivered petroleum products and can avoid static accidents thereby.
Description
Technical field
The utility model relates to a kind of static eraser, especially a kind of static eliminator that is used for hydrocarbon liquids conveyance conduits such as oil and petroleum products.
Background technique
In transportation, loading and unloading and the course of conveying of oil and petroleum products, because the generation of phenomenons such as the mutual flowage friction of oil product interlayer, eddy motion, especially in the course of conveying of pipeline, all produce a large amount of electrostatic charges inevitably, in containers such as oil tank, form high electrostatic potential, very easily cause static blast and fire accident, thereby cause very enormous economic loss.
For the electrostatic accident that reduces and prevent to be caused because of the line transportation oil product, the domestic and international pipeline static preventive measure that adopt are nothing more than two kinds at present: the one, and restriction (for example＜4.5-6m/s) adds speed oil, but when having in the oil product transporting system when being mixed with more free water or ionized impurity in filter and the oil product, limited flow rate will lose meaning, even carry this moment oil product still electrostatic accident can occur under permissible velocity.The 2nd, adopt pipeline ground connection, however the static charge of pipeline ground connection on can only the discharge conduit shell, it can not release or eliminate the static charge in the pipeline oil product, thereby this mode can not be avoided the generation of static charge discharge accident equally.Therefore, in conventional art, all can not eliminate the static charge of carrying oil product in the conveyance conduit effectively regardless of which kind of method of employing.
The model utility content:
At above-mentioned existing in prior technology deficiency, technical problem to be solved in the utility model is to provide a kind of can effectively eliminate the tubular type static eliminator of carrying the oil product static charge, makes and carries the static charge of oil product to be controlled at 30 μ C/m
3In the following safety margin.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: pipe type static eliminator, comprise the oil product delivery pipe, the compartment of terrain is provided with the electric outer tube that disappears outside described oil product delivery pipe, and this electric outer tube that disappears is fixedly attached on the oil product delivery pipe by the support flange that is positioned at its two ends; Be installed with the acusector that disappears on the described electric outer tube that disappears, the front end of this acusector that disappears passes oil product delivery pipe tube wall and stretches in the oil product delivery pipe.
When hydrocarbon liquids such as oil and petroleum products thereof are transferred by delivery pipe, the oil product that flows produces a large amount of static charges, because oil product delivery pipe and disappear and be certain span between the electric outer tube, make and carry the interior dielectric capacitance value of interior pipe to descend with the increase of this spacing, the reduction of capacitance then causes the raising of static charge current potential, thereby forms the electric field region with higher field intensity and current potential in the oil product carrier wall.Under the induced action of static charge, the reversed polarity electric charge that disappears and induce on the electric outer tube, by being fixedly mounted on the acusector that disappears on the electric outer tube that disappears, under the effect of high petential, strong electrostatic field, be injected in the oil product in the delivery pipe by its needle point, realize the neutralization of opposed polarity static charge, reach the effect of effective elimination static, make and carry the oil product static charge to be controlled at 30 μ C/m
3In the following safety margin.
A preferred implementation of the present utility model is that the spacing between the inwall of the described electric outer tube that disappears and oil product delivery pipe inwall is at least 30mm.The oil product delivery pipe and the appropriate interval of maintenance between electric outer tube that disappears, can effectively limit the capacitance between two pipes, make by medium to keep higher electrostatic potential and static field intensity, near the electrostatic charge of oil conductivity of needle point is improved, be beneficial to the raising of the neutralising capacity of positive and negative polarity static charge and the electrical efficiency that disappears.
Another preferred implementation of the present utility model is that the extrusion that the described acusector that disappears stretches in the oil product delivery pipe is 6～12mm.Because the static field intensity of oil product delivery pipe inwall near zone is the strongest, and this field intensity weakens gradually to portion of pipeline center, and therefore, the tip of the acusector that disappears extends the strength of electrostatic field, more help improving the neutralization elimination efficient of static charge, be controlled at 30 μ C/m to guarantee to carry the static charge in the oil product
3In the following safety margin.
