Construction and operation of pollution treatment facilities

  1. Decabromodiphenylethane tail gas absorption system with spray absorption for high-altitude emissions; 2. Bromopropane tail gas absorption system includes liquid alkali spraying and ozone oxidation for high-altitude emissions; 3. Decabromodiphenylethane drying tail gas is discharged at high altitude after being treated with bag dust removal.
    4. Bromine waste gas is absorbed and discharged up to standard through alkaline spray absorption; 5. Decabromodiphenyl ether exhaust gas is discharged after being sprayed with alkaline solution in the tail gas absorption tower to meet the standard; 6. After the dust is treated with a bag filter and meets the standard, it is discharged into the tail gas of 7, N, N '- ethylenebis (tetrabromo) phthalimide. There is a spray absorption system for high-altitude emissions.
