Rotary kiln wet electrostatic precipitator for removing sulfuric acid mist, fine dust particles, volatile component condensate and mixtures thereof. Wet electrostatic precipitator should be designed to meet the design criteria proposed operating conditions. Wet electrostatic precipitator characteristics: can withstand 65 ℃ operating temperature and-12Kpa operating pressure. Uniform distribution of the gas flow rate and not less than 90%. Shen dust pole should be regular hexagon shape, its inscribed circle diameter of 360mm. Wet electrostatic precipitator efficiency should ensure purified flue gas mist and dust content of less than 5 mg/Nm3. Since higher fluorine content in the flue gas treatment, all touch material must be resistant to fluorine gas corrosion. Wet electrostatic precipitator should provide complete security protection system, including security guards, interlocks, alarm and trip. External insulation materials can not be used asbestos. Wet electrostatic precipitator is overflowing with water spray or dust, water and other polar way that a water film formed on the surface will sink set on the plates of the electrostatic precipitator dust away. Wet cleaning to avoid trapping the dust and then the flying, to achieve high collection efficiency. Because there was no rapping device, running is also more reliable. But there are corrosion, sludge and waste water disposal problem. Only gas dust concentration is low, requiring high efficiency dust when used. Dedusting process conditions: Operating temperature 80 ~ 95 ℃, dedusting equipment drop is less than 5KPa, after pre-dedusting dust concentration 1000mg/Nm3 the following after import, cracked gas flow 3000Nm3/hr (excluding water vapor), the gas mainly composed of hydrogen, carbon monoxide, acetylene, tar, hydrogen sulfide, saturated steam, the export 10mg/Nm3 less dust concentration, the equipment is 60% to 120% elasticity. Dust wide size distribution, average particle size of 40 to 65 microns, and wherein about 10% of the dust particle diameter of 5 microns or less.
