The importance of static eliminators in the petrochemical industry
Fires caused by static electricity are
usually in the following three situations:
1. There are flammable and explosive items
2. The electric field strength formed by
static charge is greater than the surrounding breakdown electric field
strength;
First: Grounding.
The static charge on the conductor can be introduced into
the ground by grounding, so that the charge will not accumulate on the
conductor.
Second: Avoid the accumulation of static charges on the
human body.
The main reason for the formation of static electricity on
the human body is the charge transfer caused by the mutual friction and contact
of clothes. To effectively prevent the accumulation of static electricity on
the human body, low-resistance anti-static consumables, floors and other
anti-static equipment should be used.
Third: Ionize the atmosphere.
Because ionization can increase the
conductivity of the surrounding air, adding static charges to move on the
surface of the object, neutralizing the charge on the surface of the object
with the charge in the air after ionization, or using a certain dose of isotope
to ionize the air to neutralize the object or Static electricity in the air.
Fourth: humidification.
Increasing the humidity of the air can
improve the conductivity of the surface of the object and form a conductive
channel between the object and the ground. Usually the relative humidity is
controlled at 60%-70%, this humidity is not easy to generate static
electricity.
Notice: Under certain conditions, a person’s body can be electrostatically
charged by friction and natural environmental conditions. The “Personal
Electrostatic Eliminating Alarm” device is designed to prevent the accumulation
and accidental discharge of static electricity from a person's body.
