Abstract
A passive antistatic equipment for petroleum and petroleum products has a circuit board for absorbing and eliminating the electrostatic charges. Said circuit board is connected to a clamper via a cable at its one end and to a grounding cable at its another end. Its advantage is high effect.
Description
Technical field
The present invention relates to the passive static eliminator of a kind of oil and petroleum products.
Background technology
Oil and petroleum products are in transportation, loading and unloading and transmission course, because the phase mutual friction of oil product interlayer, the eddy current type motion can appear at truck tanker, holding vessel interior section oil product, cause each layer of oil product structure to change, produce electrostatic charge, induce high voltage, thereby produce spark in the inner oil gas air mixture of environment and oil tank around, cause fire, explosion accident.It is reported, the fire that oil and petroleum products cause because of Electrostatic Discharge in transportation, loading and unloading and transmission course, explosion accident are at whole world ubiquity, the economic loss that causes is very huge, american petroleum enterprise takes place surplus the electrostatic hazard 10 every year on average, Japan takes place surplus the electrostatic hazard 20 every year on average, and domestic truck tanker, the tank car of also often taking place is in transportation or handling process electrostatic hazard accident.For the accident that reduces and prevent to cause because of ESD, related organization all strengthens oil and petroleum products is being transported both at home and abroad, the disappear electrostatic technique research of loading and unloading and transmission course, relevant patent is a lot, as: domestic have " mobile oil tank is led the electrostatic safety monitor " notification number 2266134, " the bad annunciator of electrostatic grounding " notification number 2122393, " explosion-proof ground connection controller " notification number 2076241, " mobile oil tank is led static, the safety monitoring instrument " notification number 2226772, " Grounding system and detection circuit forfueling " US5159523 etc. is abroad arranged, these patents all adopt direct ground connection of equipment surface and active ground detecting method, for inflammable and explosive, the clean cargo that conductivity is high adopt the method can not derive oil tank in-to-in electric charge, and when ground connection connects, very easily produce spark, form new dangerous matter sources.
Summary of the invention
The purpose of this invention is to provide the passive static eliminator of a kind of oil and petroleum products, it can solve the problems referred to above that prior art exists.
The passive static eliminator of a kind of oil and petroleum products is characterized in that having electrostatic charge to absorb and eliminate the circuit card of circuit, places in the explosion-proof shell, and an end A of this circuit connects a cable, this cable connection one folder, and the other end B of this circuit connects an earth cable.
Advantage of the present invention is the electric charge that absorbs oil and petroleum products in the oil tank under the situation of no additional power source by electronic circuit, and in explosion-proof shell, eliminate, its effect is suitable with active X eliminator, makes it have characteristics safe, quick, that science is eliminated oil and petroleum products static in fire prevention, explosion-proof place.
