Description
Technical field
This utility model relates to the electrostatic precipitator technical field in the industries such as electric power, building materials, iron and steel, chemical industry, especially
It it is the electric cleaner micro unit cross-flow type anode assembly that can effectively suppress reentrainment of dust.
Background technology
Electrostatic precipitator is a kind of efficient, energy-conservation industrial waste gas abatement equipment, and its operational efficiency, up to more than 99.5%, has
There are the plurality of advantages such as stable, a little repair, running resistance are low, are industrial waste gas one of the leading equipment of administering industry.
Conventional electric cleaner relies primarily on discharge electrode and dust collecting electrode the two system completes, and i.e. uses high pressure ionization technology, by height
Pressure electrostatic (V=7.2 ten thousand volts～100,000 volts) makes air ionization in electric field, and the negative ions that produced by ionization and electronic high-effective
Catch dust, make the neutral dust of entrance electric field almost 100% become electrically charged dust, thus to its pole under the effect of electric field force
Property contrary electrode move, and adsorbed by dust suction pole (positive plate, cathode line), after release electric charge, entered by rapping apparatus
Row deashing, dust stratification drops to ash bucket and is recovered.
The purge mode that existing electrostatic precipitator uses has mechanical vibration type, low-frequency sound wave cleaning formula etc., and mechanical vibrator is usual
Being to arrange a cathode line rapping apparatus and an anode polar curve rapping apparatus in each electric field, this kind of purge mode is clear at it
More serious dust raising phenomenon all can be had during ash to occur, be particularly acute especially with dust raising phenomenon during low-frequency sound wave deashing,
The critical defect failing again to overcome that this electric cleaner being currently used generally exists: i.e. produce two during vibration dust-cleaning
Secondary airborne dust, owing in electric field, flue gas flow rate is higher general at about 1m/s, the reentrainment of dust of generation can not be completely by dust suction pole
Absorption, the flue gas higher along with flow velocity is pulled away, particularly in last electric field, it is impossible to the secondary adsorbed by dust suction pole
Airborne dust is directly discharged in air by blower fan, chimney so that the efficiency of dust collection of electrostatic precipitator can only achieve more than or equal to 98.5%,
To such an extent as to it is difficult to ensure that the latest requirement of national environmental standard.The dust-laden index of National Industrial waste gas discharge at present was by the past
300mg/Nm3Bring up to 50mg/Nm3, present key cities are by this standard upgrading to 30mg/Nm3Hereinafter, so
Electrostatic precipitator produces the feature of reentrainment of dust it is determined that himself performance cannot meet this environment protection emission requirement, the most quiet
Electric cleaner faces the danger eliminated by industry, but does not has again a kind of more preferably dedusting equipment can produce as its replacement
Product.Some enterprises have to select sack cleaner, electricity bag combined dust remover to replace electrostatic precipitator, but both is removed
Dirt device running resistance is big, cloth bag cracky, safeguard inconvenient and operating cost is high, use to user bring many not
Just.Flue gas flow rate is reduced, it is also possible to increased by electrostatic precipitator volume, so will result in cleaner unit for increasing dust-collecting area
Floor space and power consumption are greatly increased, thus investment also will be significantly increased with operating cost, use this currently without an enterprise
Plant dust-cleaning scheme.
Utility model content
