First, scope of
application
Products are mainly used in
chemical fertilizer, coking, city gas, metallurgy, building
materials, gas purification of carbon, ceramic and other
industries, to recycle gas, coke oven gas in the tar, at the same
time to remove the impurities such as dust, water spray, material
recovery and gas purification effect, to ensure normal and stable
operation of the process equipment in the section also plays an
important role.
Second, the tower body
analysis
1, JTD concentric circles type
electric tar precipitator
2, JFD cellular electric tar
precipitator
3, JFD wet/dry type electric tar
precipitator
4, JGD tubular electric tar
precipitator
Cellular, shell and
tube type and concentric circles type electric tar precipitator is
mainly used for gas purification with high tar, light oil; Wet
electric catching tar valued to be used in the gas purification of
high dust content.
Third,
structure
Four types of the
electric tar precipitator is composed of shell, precipitation,
upper and lower hanger, gas distribution board, purge steam pipe,
insulation box and feed box parts, such as the main difference in
the precipitation of the form, the corona polar arrangement way,
insulation box and feed box.
Four, principle of
work
Working parts of the
body of the electric tar precipitator is made up of corona
extremely extremely and precipitation. High voltage dc power supply
to produce negative pressure, access corona (cathode), which
produces an electric field between it and precipitation pole
(anode), electric field intensity exceeds a certain limit after
that produce corona discharge between Yin and Yang. Through the
electric field at this time the gas ionization, produce a large
number of ions and electrons. Electromagnetic around you can hear a
strong wind. Visible when the light dark purple blue corona. By
electric tar in gas, dust and water mist or electronic combination
and charged particles and ions, under the action of electric field
force to the poles. Because the quality is small, movement speed,
wide spatial distribution, so the main is burden electric
precipitation particles to extreme sports. To precipitate plates
after neutralization, rely on residual electrostatic attraction and
cohesion between the molecules adsorbed on the precipitation, the
first and then fall by its own gravity along the plate, through the
tar outlet. In addition, near the corona pole with positive charge
of the tar particles are corona wire adsorption, surface flow along
the wires and converge into the bottom of the device, after
purification, the gas flowed from the top equipment.
