WSRLFJ Medical waste incinerator

Process Description

     Medical waste is conveyed automatically into the first chamber(830-980⁰C), drying and pyrolysis begin and follow the incineration, heat generated speeds up the  drying and incineration. Flue gas is then fully combusted in the second chamber(1050-1150⁰C), full mixing and enough residence time is guaranteed in the third chamber(800-980⁰C) due to special shape and rotating air supply, flue gas is rapidly cooled going through the tube type heat exchanger, acid components are removed by semi dry process, fly dust is collected in bag filters and activated carbons are injected to absorb hazardous components before release into the air.

Incinerator body and feature

     The primary and secondary incinerators are divided into three compartments by refractory walls, carbon rich smoke is thermally oxidized in form of cyclone in the secondary and third chambers to ensure 3T in medical waste combustion, residues are removed from the bottom of the incinerator.

Specifications:

Residues thermal volume reduction:≤5%

Surface temperature:<50^oC

Residence time:>2 seconds

Temperature:830-1150 ^oC

     Refer to report No.016,2004 issued by Sichuan Environment Protection Product Examination Center and  report No.003,2005 issued by National Environment Analysis and Test Center for pollutants test results.

Capacity:

50,100,200,300,500,750(kg/h)

    Output connection is reserved in the third chamber for heat or power generation.

    Examination with authenticate

    Flue gas is tested by National Environment Analysis and Test Center and  Sichuan Environment Protection Product Examination Center to be in compliance with GB19219-2003«Medical Waste Incinerator Technical Requirements»,the incineration system is approved by the experts examination organized by the Sichuan provincial EPA.

Medical Waste Incineration System Test Conclusions
