Incineration rotary kiln is a kind of equipment commonly used for the treatment of solid waste, hazardous waste and medical waste. Incineration rotary kiln has a wide range of applications. The following is a detailed introduction:

Treatment of industrial hazardous waste

1. Chemical industry: A large amount of hazardous waste will be generated in the chemical production process, such as waste organic solvents (such as waste of organic solvents such as benzene, toluene, chloroform), waste catalysts (containing heavy metals and other components), and waste acids and alkalis (corrosive). Incineration rotary kilns can decompose these organic harmful substances at high temperatures, convert organic components into carbon dioxide and water, and stabilize inorganic components such as heavy metals to prevent harmful substances from leaking into the environment.

2. Pharmaceutical industry: Pharmaceutical companies will produce various organic wastewater and waste residues. For example, the drug residues contain a large amount of organic components, and there may be residual active drug ingredients. Through incineration rotary kiln treatment, these organic components can be completely destroyed to prevent them from polluting the soil and water. Moreover, high-temperature incineration can effectively kill possible pathogens and reduce biological hazards.

3. Electronics industry: Electronic waste such as circuit boards contain a variety of heavy metals (such as lead, mercury, cadmium, etc.) and organic pollutants. Incineration rotary kilns can pre-treat these electronic wastes, first decompose organic matter through high-temperature incineration, and then recycle or safely landfill the heavy metals in the ashes to achieve resource recovery and harmless treatment.

4. Metallurgical industry: Hazardous wastes such as waste slag (such as steel smelting waste slag) and sludge (sludge after wastewater treatment containing heavy metals) generated in the metallurgical process can also be treated by incineration rotary kilns. By incineration, the volume of waste slag can be reduced, and heavy metals can be fixed in the ashes, which is convenient for subsequent treatment.

Medical waste treatment

1. Internal waste treatment in hospitals: The medical waste generated by hospitals has complex components, including disposable medical devices (such as syringes, infusion tubes, etc.), surgical dressings (containing blood, human tissue, etc.), drug packaging and expired drugs. These medical wastes carry a large number of germs and viruses. The incineration rotary kiln can quickly kill these germs and viruses at high temperatures (generally up to 850-1100℃), and at the same time burn out the organic components in the waste. The amount of ash generated is relatively small, which greatly reduces the volume of medical waste, and the residue after incineration can be safely landfilled.

2. Centralized medical waste treatment center: Centrally treat the medical waste generated by multiple medical institutions. The incineration rotary kiln has a strong processing capacity and can efficiently treat a large amount of medical waste to ensure public health safety.

Urban domestic waste treatment

1. Domestic waste incineration power generation project: There are a large number of organic matter (such as food residues, paper, wood, etc.) and some inorganic matter in urban domestic waste. The incineration rotary kiln can be used as part of the domestic waste incineration system to burn the organic components in the waste and use the heat energy generated for power generation. This can not only reduce the land occupied by landfills, but also achieve energy recycling.

2. Harmless treatment of domestic waste: For some domestic waste that is not suitable for recycling, incineration through incineration rotary kilns can destroy harmful components in the waste, such as some difficult-to-degrade organic matter and harmful microorganisms, achieve harmless treatment of domestic waste, and reduce the risk of environmental pollution.

Sludge treatment

1. Sludge treatment in urban sewage treatment plants: A large amount of sludge is produced during the treatment of urban sewage. These sludges contain a large amount of water, organic matter, microorganisms and heavy metals. Incineration rotary kilns can evaporate the water in the sludge, burn and decompose organic matter, and enrich heavy metals in the ash. After incineration treatment, the volume of the sludge is greatly reduced, which is convenient for subsequent landfill or recovery of useful components in the ash.

2. Industrial sludge treatment: Sludge produced after industrial wastewater treatment (such as printing and dyeing sludge, papermaking sludge, etc.) can also be treated by incineration rotary kilns, thereby solving the problem of industrial sludge disposal and reducing its potential harm to the environment.
