Product description
Hazardous waste solid waste rotary kiln mainly treats waste with
one or more hazardous properties such as toxic, explosive,
flammable and corrosive.Currently, there are two main ways to
dispose of hazardous waste: incineration and landfill. Among them,
the hazardous waste solid waste rotary kiln incineration technology
is currently widely used hazardous waste treatment technology, and
is becoming an important way for the harmless treatment of
hazardous waste.
【Applicable materials】
Industrial comprehensive hazardous waste, medical waste, petroleum,
chemical, pesticide and other industries of various solid waste,
waste liquid, waste gas. Municipal domestic waste, etc.
Advantage
1.Low cost:high temperature material contacts refractory. Easy to change
lining
2.The drive mechanism is simple: the drive mechanism is inside the kiln shell. Equipment
maintenance is convenient.
3.To ensure no leakage of harmful gases: good sealing measures and negative pressure in the furnace.
4.Convenient operation and maintenance: high equipment operation rate. The annual operating rate is
generally 90%
5.Incineration adaptability: solid waste, liquid, colloid and gas can be incinerated at the
same time
6.High heat utilization rate: the material is stirred forward. Three heat transfer modes coexist
in one furnace
7.Combined with patented technology: the traditional secondary combustion chamber has evolved into a
secondary combustion furnace. Increases ash burn rate. Improve the
combustion efficiency of the rotary kiln. At the same time, it has
the functions of normal temperature slag discharge, slag breaking,
air lock and so on.
Process flow
Pretreatment feeding system - rotary kiln + secondary combustion
chamber combustion system - waste heat recovery system - waste gas
purification system - flue gas emission incineration system:
including hopper, rotary kiln, secondary combustion chamber and
combustion, fan, etc. Auxiliary equipment. Waste heat recovery
system: including waste heat boiler and boiler auxiliary system
equipment. Flue gas purification system: Cool the flue gas in the
incinerator, remove harmful substances, and discharge it after
meeting the emission requirements. Including quench tower, dust
collector, scrubber, flue gas heater, activated carbon supply
system, ash removal system, etc. Flue gas emission system:
including induced draft fan, chimney, etc.

Rotary Kiln Incinerator Working Principle:
Rotary Kiln Incinerator can deal with solid and liquid waste
simultaneously, solid waste is sent into rotary kiln by special
conveying equipment, liquid waste is sprayed into the feed end of
the Rotary Kiln Incinerator body by means of an efficient atomizing
device, the waste in the rotary kiln should experience the process
of water evaporation, volatilization analysis, ignition and
combustion process, The ash portion is discharged from the bottom
of the second combustion chamber, the generated flue gas enters the
second combustion chamber, blended with two combustion air in the
second compartment, complete combustion of flue gas, achieve
exhaust safety standards discharge.
