The comprehensive treatment of atmospheric multi-pollutants refers to the VOCs, NOx, SO in the exhaust gas2, HCl, O3Harmful gases, such as heavy metals and dioxins, are collaboratively removed by adsorption or catalytic technology。
Background of air pollutant control
Technological advantage
(1) Optimize the flue gas treatment process route
(2) Reduce investment and operating costs
(3) Reduce new equipment investment, small footprint
(4) Easy to install and maintain
(5) Multi-pollutant collaborative treatment efficiency is high
Typical application case
Collaborative treatment technology of volatile organic waste gas (VOCs) containing nitrogen/sulfur/chlorine
1. Technical introduction
Volatile organic waste gas (VOCs) containing nitrogen sources will form a certain concentration of nitrogen oxides (NOx)/sulfur dioxide (SO2)/hydrogen chloride (HCl) in the process of direct or regenerative combustion (or catalytic combustion).,Then it was treated by dry deacidification and selective catalytic reduction (SCR),Finally achieve the synergistic ultra-low emission of organic waste gas and nitrogen oxides。
2. Technical characteristics
(1) High purification efficiency, VOCs removal rate of more than 99%, NOx removal rate of more than 90%
(2) The application temperature of collaborative treatment technology is broad
(3) Low one-time investment cost and energy saving
(4) Flexible process layout, small footprint
(5) Easy to operate, high degree of automation, safe and reliable operation
3. Process route
高效Dry process酸Dust removal catalysis协同技术
A new filter bag catalytic (oxidation/reduction) technology is used to remove a variety of pollutants (NOx, VOCs, CO, dioxins, etc.) in the flue gas (after acid removal) in a collaborative and efficient dust removal system。
2. Technical characteristics
(1) To achieve efficient collaborative treatment of multiple pollutants
(2) Wide temperature range (150-260)oC)
(3) Low system pressure differential
(4) Saving energy costs
(5) Easy to operate and replace
