Abstract
Abstract This invention is directed at an infectious waste incinerator system using primary and secondary combustion chambers to reduce the waste to gaseous and particulate matter. Which is passed through a waste heat recovery boiler reduces the temperature of the gaseous and particulate matter and send the recovered heat to pipes. The cooled gaseous and particulate matter is passed to a baghouse packed-bed scrubber where the gaseous and particulate matter is further cooled and diluted. The gaseous and particulate matter is then passed to the lower end of a packed-bed scrubber when it is passed to a treatment tank where it is subjected, in a neutralizing compartment, to a hydroxide and is also surface skimmed. The skimmed material is passed through a filter system and then returned to the treatment tank. The gaseous treated material is pumped back into the packed-bed scrubber and then out an exhaust stack.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
A waste disposal system for controlled burning and safe disposal of contaminated materials comprising a means of holding the contaminated materials having a feed means associated therewith, the feed means transporting the contaminated materials to an incinerator chamber, the incinerator chamber providing a combustion of the contaminated materials, the incinerator chamber in communication with a bag filter which is connected to a packed column scrubber, the packed column scrubber including a first packed bed and a second packed bed and means of maintaining the bag filter at a temperature above the dew point of HCl the first packed bed in communication with the second packed bed, the packed column scrubber having a sump tank connected thereto, an exhaust stack in communication with the packed column scrubber for exhausting the smoke from the packed column scrubber to an external environment, the smoke substantially free of hazardous contaminants.
Claim 2
Dependent Claim
146 words
A waste disposal system for controlled burning and safe disposal of contaminated materials comprising a means of holding the contaminated materials having a feed means associated therewith, the feed means transporting the contaminated materials to an incinerator chamber, the incinerator chamber providing a combustion of the contaminated materials, the incinerator chamber in communication with a bag filter which is connected to a packed column scrubber, the packed column scrubber including a first packed bed and a second packed bed and means of maintaining the bag filter at a temperature above the dew point of HCl the first packed bed in communication with the second packed bed, the packed column scrubber having a sump tank connected thereto, an exhaust stack in communication with the packed column scrubber for exhausting the smoke from the packed column scrubber to an external environment, the smoke substantially free of hazardous contaminants.
