Solid (dangerous) waste incineration system
Hazardous waste refers to materials with hazardous characteristics, which have one or more hazardous characteristics such as toxicity, explosive, inflammability, corrosion, etc. At home and abroad, the disposal of hazardous waste is quite important. The current hazardous waste treatment methods mainly include incineration and landfill, among which the rotary kiln incineration treatment technology is currently widely used in the treatment of hazardous waste. It is becoming an important way of harmless treatment of hazardous waste.
Main equipment: pretreatment and feed system, rotary kiln + secondary combustion chamber combustion system, waste heat recovery system, tail gas purification treatment system
Applicable materials: tailings, tailings, white mud, calcium carbide slag, aluminum ash, contaminated soil, municipal medical waste, domestic sludge, acid washing sludge and other materials
Application: industrial hazardous waste, medical waste, petroleum, chemical, pesticide and other industries of all kinds of solid waste, liquid waste and waste gas
Capacity: 10-120t/d
Outstanding advantage
1, Can simultaneously deal with waste water/waste gas/liquid waste three kinds of waste;
2, Waste heat recovery, produce benefits;
3. Wide application range, strong material adaptability, large processing capacity, strong moisture content resistance and other advantages.
Characteristics of rotary kiln incineration system
1, The incineration technology can not only meet all the environmental requirements of hazardous waste (medical waste) harmless treatment, but also the recommended technology for solving hazardous waste in our country.
2. Wide application range, strong material adaptability, large processing capacity, strong moisture content resistance and other advantages; The furnace heat load is large, the material is completely incinerated, enough to cope with the complete incineration of a large number of hazardous wastes, even if the calorific value and moisture content of the material have some fluctuations, it can be completely incinerated. It is suitable for incineration of comprehensive hazardous waste.
Characteristics of medical and industrial hazardous waste systems
1, can simultaneously deal with waste water/waste gas/liquid waste three kinds of waste;
2, liquid waste feed using micron atomization, combustion is complete, saving fuel consumption;
3, waste heat recovery, produce benefits;
4, DCS control, high degree of automation;
5. Wide application range, strong material adaptability, large processing capacity, strong moisture content resistance and other advantages;
6, the furnace heat load is large, the material incineration is thorough, enough to cope with the complete incineration of a large number of hazardous waste, even if the calorific value and moisture content of the material have some fluctuations, it can be completely incinerated. It is suitable for incineration of comprehensive hazardous waste.
