Description
Technical field
The present invention relates to a kind of electric dust collection device with tornadotron, specifically a kind of Horizontal electric dust collector integrating gravity, cyclone dust collection.
Background technology
Cyclone dust removal is the centrifugal force utilizing the dusty gas rotated to produce, a kind of dry type gas-particle separation device separated from air-flow by dust.Dust efficiency for trapping, separation 5 ~ more than 10um is higher, and be characterized in that structure is simple, Operation and Maintenance is simple, and operating characteristics is stablized, not by the temperature limiting of dusty gas.
Cottrell is the device utilizing the fine grit of electrostatic attraction thus gas purification is reached gather dust object.Have the grit of below particle diameter 5um and well catch effect, if service condition is suitable, its efficiency of dust collection can reach 99% even higher.Its advantage is: dust-collecting efficiency is high, and smoke treatment amount is large, consumes electric energy few, be adapted to the recovery of high-temperature flue gas, and automaticity is high.
The research comparative maturity of the current dust collector pole for cottrell, corona discharge electrode and rapping aspect.The domestic research for the combined cottrell of principle is fewer at present.Hybrid E-precipitator (patent No.: CN201030328) the utility model discloses a kind of hybrid E-precipitator, comprise housing, blast pipe, air outlet, central air hose, vibrator, corona electrode, ash bucket, ash-valve, equal flow cone, ash bucket is arranged on the bottom of housing, the below of ash bucket is provided with ash-valve, central air hose is arranged on the interior central authorities of housing, corona electrode is provided with between the lateral surface of central air hose and the medial surface of housing, the top of housing is provided with blast pipe and is connected with central air hose, the top of housing is also provided with air outlet, the lateral surface of housing is provided with vibrator, the below of central air hose is provided with equal flow cone, also comprise in central air hose and be provided with break-in flow plug successively, lower break-in flow plug, the below of equal flow cone is provided with dust-laying taper, bottom air distribution plate is provided with between the inner bottom part of housing and central air hose outer bottom.The utility model can make crude particle dust realize pre-separation effectively, and the concentration of the dusty gas entering dedusting electric field region is reduced greatly.Because realize in cyclone dust collection centre airduct, cyclone cylinder axial dimension is consistent with electric field height direction, and therefore cyclone cylinder axial dimension is large, in addition because cyclone cylinder can only be centre, when processing air quantity and being large, cyclone cylinder size can only be made to increase, thus cyclone dust collection weak effect.Cyclone-type electric dust collector (patent No.: CN1266744) cyclone-type electric dust collector is that a kind of centrifugal inertia, electric-field charge and electric field of integrating filters the cleaner gathered dust.Its principal character is: by the rotation of driven by motor rotor, guide and force the dusty gas entered in electricity receipts electrical equipment to rotate and motion, rotor is provided with fan blade and electrode, form intensive electric field net at the High Rotation Speed of rotor simultaneously, be provided with different electrodes according to different principles outside rotor form different electric fields and interact, along with rotation and the motion of gas, dust is collected under centrifugal force and electric field force effect and in intensive electric field net.This cottrell guides flow rotation by rotor, structure relative complex.
Combination vertical cylinder type electric duster (patent No.: CN2329446) is a kind of combination vertical cylinder type electric duster, and belong to dedusting technology field, it is combined by cyclone dust collector and electric dust collector.Cyclone dust collector is made up of multiple Whirlwind cyclone, and each Whirlwind cyclone is coaxial with superposed electric field.Electric dust collector is vertical barrel, and its dust collector pole is connected by multiple square prism-frustum-shaped umbrella sheet and formed, and dust falls into large ash bucket from umbrella sheet outer rim, and the large ash bucket that whirlwind seed cell is provided with little ash bucket and electric cleaner divides ash of starting discharging, and avoids reentrainment of dust.This dust arrester compared with the combined electrical dust-precipitator used at present, have efficiency of dust collection high, do not produce the advantages such as reentrainment of dust, maintain and replace are simple, be applicable to the dedusting of high concentration dusty gas.This dust-precipitator is combination cyclone dust collection principle, but is an independently individuality because cyclone cylinder is each, so system air leakage is larger, affects the stable operation of cottrell.Because there is aid distributing pipe, make total complicated.
At present gravity is gathered dust, research that cyclone dust collection and Horizontal electric dust collector carry out principle combination also do not have.
