1. Low-Low Temperature Electrostatic Precipitator Technology
Low-low temperature electrostatic precipitator technology involves installing a flue gas cooler (low-temperature economizer) before the flue gas enters the dry electrostatic precipitator, reducing the flue gas temperature below the acid dew point to cause SO3 condensation. This lowers fly ash specific resistance to improve dust removal efficiency of the electrostatic precipitator, while also removing sulfur trioxide, controlling PM2.5 emissions, and recovering flue gas waste heat.
Features of low-low temperature electrostatic precipitator system:
l Boqi low-low temperature electrostatic precipitator system has no corrosion, no blockage, long service life, and stable operation
l Low-temperature economizer using spiral finned tubes can reduce exhaust gas temperature to about 85℃, maximizing dust removal and energy-saving effects
2. Wet Electrostatic Precipitator Technology
Installing a mist eliminator or wet electrostatic precipitator at the end of the flue gas process can further reduce dust and droplet emissions from the absorption tower outlet, more effectively controlling PM2.5.
Features of wet electrostatic precipitator technology:
l High dust removal efficiency, high removal rate for submicron particles;
l Can effectively treat high-humidity dusty gases; also removes some soluble gaseous pollutants from flue gas simultaneously;
l Not affected by fly ash specific resistance, no secondary dust raising, no moving parts;
l Effective capture of PM2.5;
l Removes SO3 acid mist, alleviating corrosion of flue and chimney;
l Comprehensive collection function for multiple pollutants;
3. Low-Pressure Rotary Pulse Jet Bag Filter
Low-pressure rotary pulse jet bag filter is suitable for dust pollution control in large thermal power generation, steel metallurgy, building materials, and other industries, and has been widely applied in China's 300MW, 200MW, and 100MW thermal power units.
Technical features:
l Compact structure, convenient operation and maintenance, low operating resistance;
l Long service life of filter bags;
l Low cleaning pressure, low energy consumption;
4. Electrostatic-Bag Composite Dust Collector
Electrostatic-bag composite dust removal technology uses high-efficiency electrostatic precipitator in the front stage and low-pressure rotary pulse jet bag filter in the rear stage. This technology is widely used in boiler flue gas purification in large and medium-sized thermal power plants, as well as large steel metallurgy, building materials, and other industries.
Technical features:
l Electrostatic precipitator uses zoned power supply;
l Airflow distribution devices are installed separately in the electrostatic precipitator and bag area;
l Uses non-membrane filter media;
l Allows online inspection and maintenance;
