The construction scale of demonstration project is 15tons per day. The major incineration system is vertical continuous pyrolytic incineration system with semi-dry flu gas purification, active carbon injection and bag filters.
The entire process is feeding— primary incinerator— secondary incinerator—waste heat boiler – quenching tower—deacidity tower— active carbon injection — bag filters.
After high temperature flu gas enter waste heat boiler, temperature was dropped from 1200ć to 600ć and produced 0.98 MPa steam. The steam could use for bag filter, room heating, bath water and so on.
The 600ć flu gas entering quenching tower, atomized cold water cooled the flu gas to 200ć within 1s.
And then the flu gas entered deacidity towerˈatomized NaOH solution will neutralize acid pollutants in flu gas.
The active carbon injection with spiral plate feeder was ahead of bag filter. The active carbon was added to spiral plate and negative pressure of flu gas tunnel could suck the active carbon.
Dioxin, heavy metal, smoke dust and other pollutants was absorbed and removed within bag filter.
Purified flu gas was released through 35 meters stack
