The present invention is simple in structure, convenient in installation and use, safe and reliable.
Description
Technical field
The present invention relates to a kind of ignite safety device of hazardous areas such as (quick-fried) of static that is used for, specifically can eliminate the static eraser of static electricity on human body lotus.
Background technology
In the high-risk place of static such as inflammable, explosive, in transportation, loading and unloading and the production operation process as oil and petroleum chemicals, because operating personnel's activity, induction, absorption and capture " charged " microgranule, human body has electrostatic charge inevitably, and has quite high electrostatic potential, produce discharge spark, explosion caused and fire incident in the hazardous environments such as oil gas very easily around and dust.
Data shows according to the study, and only in the transportation of oil and oil product, operation process, blast that causes because of human body electro static discharge and fire incident be equal ubiquity in the whole world, all causes very enormous economic loss every year.Over nearly 20 years, there is static electricity on human body's accident of statistics to surpass 235 as Japan; Same domestic oil tank, the electrostatic hazard accident of tank car in sampling or cargo handling process of also often taking place constitutes great the threat for people's lives and properties.
In order to prevent and to reduce the explosion accident that causes because of the static electricity on human body, people have carried out deep countermeasure and corresponding product development to the electrostatic hazard and the management in oil gas, dust place, have formed active or passive static eliminator.But these eliminostatic measures only are applied to the non-explosion-proof place before personnel enter the working area, and after entering the working area for the operating personnel, the electrostatic charge that produces again or accumulate again because of movable and operation, as tank deck sampling, detecting operation, refuel on the tank car top, emptying is operated and device is distinguished sampling or the like, then, still can cause the static explosion accident in high-risk place in the working area because of the elimination of releasing of static electricity on human body lotus.Because of not using existing direct-type static eraser, have to take the preventive measure of some restriction operations, attempt whereby to reduce the generation of electrostatic charge and gather, often effect is unsatisfactory but these measures are to high-risk working area, still causes electrostatic accident often.
Summary of the invention
Technical problem to be solved by this invention provides a kind of human body electrostatic eliminator, and its static electricity on human body that can release effectively can suppress the discharge energy in the human body touch ground connection process again reliably.
In order to solve the problems of the technologies described above, human body electrostatic eliminator of the present invention, it comprises electrostatic conductor, is socketed with electrostatic current suppressing sleeve on this electrostatic conductor.
Be socketed with electrostatic current suppressing sleeve on the partial-length of described electrostatic conductor, this electrostatic current suppressing sleeve adopts the electrostatic subconductor material.
Described electrostatic conductor is the metal tube of ground connection.
After adopting said structure, owing to be socketed with electrostatic current suppressing sleeve on the electrostatic conductor of ground connection, when charged human body touch electrostatic current suppressing sleeve, because of electrostatic current suppressing sleeve has improved electrostatic bleeder resistance value, the release of static discharge current is restricted and reduces, solved the eliminostatic problem of high-risk working area effectively.When human body touches this ionotron in high-risk working area, the discharge energy suppression ratio can reach 98%-99%, human body is charged ± and maximum discharge charge transfer amount is about 0.0173 μ C during 6KV, much smaller than lighting 0.1 required μ C discharge energy of gasoline class gas (IIA class); Human body is charged ± 6KV, touch canceller 2S after, dump energy is less than 0.26mJ (gasoline series products minimum ignition energy); After touching 5s, the human body residual amount of energy is 0.007mJ to the maximum, less than H
2IIC class gas minimum ignition energy such as (MIE=0.019mJ).
Electrostatic conductor is the grounded metal pipe, has guaranteed that by holder canceller is connected with conduction reliably between the earth.Special-purpose ground terminal or earth clip are arranged on described electrostatic conductor, can be used for operation utensil ground connection such as sampling, thermometric, guaranteed the safety of operations such as sampling, thermometric.
