What is the best air pollution control technology to be used in clinical incinerator ?
The best air pollution control technology for clinical waste incineration is the incineration technology itself. For such waste, advanced incineration should be used in incinerators equipped with a combustion chamber and a post-combustion chamber. Since an important fraction of medical waste is PVC along with other plastics, it is essential that a temperature of at least 1100 deg.C is ensured in the post-combustion chamber to minimize the risk of generating polychlorinated dioxins and difurans (PCDD, PCDF). Also, it is important that the cooling of the incineration gases is very fast. To control the accidental pollution level with such toxic compounds in incineration gases, the GC/MS technique should be used.
Dioxins analysis using a gas chromatograph coupled with a mass spectrometer (GC/MS).
It depends on the dry scrubber type. Such cleaning components are used primarily for removing particulate matter and acid gases from incineration gases but some activated carbon-based scrubbers are efficient for polychlorinated dioxins and difurans too.
Hello if GC/MS better with Thermal desorption or headspace system for more accurate air monitoring.
For dioxins analysis you need GC with triple quadrupole mass spectrometer or High resolution MS.
Good question , i agree with Dabrinyan, K.A. " mass spectrometer or High resolution MS"
Depends on your outlet Dioxin emission limit, combining with dry/wet scrubber and bag filter, activated carbon (powder carbon) can be considered, and a fix bed AC bed(granular/pellet carbon) can be installed at the end before the alkaline scrubber to further reduce the Dioxin-like compounds < 0.1 ng/Nm³ TEQ.
plant Tree and different kind of plant it will be better to fix problem with pollution
A well designed system will consist of:
1. Combustion Chamber w/2 sec retention time; and with a minimum temperature of 2050 F.
2. Flue Gas Treatment. Dry Scrubber (Hydrated Lime) followed by a Baghouse with PTFE Bags operating at 500 F; and finally a Polishing Wet Scrubber using Sodium Hydroxide. A zero discharge system can b designed by taking the slurry discharge from the packed tower wet scrubber and injecting it upstream of the Baghouse.
3. For Dioxin Control, Activated Carbon should be injected upstream of the Baghouse.
