This is ourcompany designed JFD420 - type A cellular electric tar precipitator, for henan kefengcarbon materials co., LTD.loading the delivery site, On February 14, 2012.

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 thesame time to remove the impurities such as dust, water spray, material recoveryand gas purification effect, to ensure normal and stable operation of theprocess equipment in the section also plays an important role.

Second, the tower body analysis

1, JTD concentric circles type electric tarprecipitator

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 andconcentric circles type electric tar precipitator is mainly used for gaspurification with high tar, light oil; Wet electric catching tar valued to beused in the gas purification of high dust content.

Third, structure

Fourtypes of the electric tar precipitator is composed of shell, precipitation,upper and lower hanger, gas distribution board, purge steam pipe, insulationbox and feed box parts, such as the main difference in the precipitation of theform, the corona polar arrangement way, insulation box and feed box.

Four, principle of work

Workingparts of the body of the electric tar precipitator is made up of coronaextremely extremely and precipitation. High voltage dc power supply to producenegative pressure, access corona (cathode), which produces an electric fieldbetween it and precipitation pole (anode), electric field intensity exceeds acertain limit after that produce corona discharge between Yin and Yang. Throughthe electric field at this time the gas ionization, produce a large number ofions and electrons. Electromagnetic around you can hear a strong wind. Visiblewhen the light dark purple blue corona. By electric tar in gas, dust and watermist or electronic combination and charged particles and ions, under the actionof electric field force to the poles. Because the quality is small, movementspeed, wide spatial distribution, so the main is burden electric precipitationparticles to extreme sports. To precipitate plates after neutralization, relyon residual electrostatic attraction and cohesion between the moleculesadsorbed on the precipitation, the first and then fall by its own gravity alongthe plate, through the tar outlet. In addition, near the corona pole with positivecharge of the tar particles are corona wire adsorption, surface flow along thewires and converge into the bottom of the device, after purification, the gasflowed from the top equipment.Email:31316108@qq.com
