Product Description

Introduction:
Having combined with AEE's extensive experience in hazardous waste incineration and TSK's proven technology in industrial furnaces, we have developed a new hazardous waste incineration system. This system is a new generation of environmental-friendly incineration system developed by using the latest research results. Compared with traditional incineration technology, this system can fully meet the stringent environmental regulations in the future.
According to different demands of customers, we can provide three types of furnaces, which is slag type, non-slag type and pyrolysis type.

Incineration system:
The rotary kiln incineration system is ideal for handling industrial hazardous wastes. It can handle not only solid, liquid and gaseous hazardous waste, but also sludge. We can provide a whole set of incineration equipment (including feeding system, rotary kiln, secondary combustion chamber and slag discharge system), as well as EPC services. We can formulate different flue gas treatment systems according to different emission requirements to ensure that the flue gas emissions comply with local environmental regulations.

• Feeding system
The feeding system is mainly used to quantitatively deliver wastes into the rotary kiln and prevent smoke from overflowing. This system can include: a solid waste feeder, a sludge and liquid pumping system, and a gas injection system.
• Rotary kiln
The temperature in the rotary kiln is 850°C to 900 °C. After the wastes enter the kiln, as the kiln rotates, the ash slag kiln is continuously tumbling and burning, and then is discharged from the end of kiln. The kiln speed, temperature and oxygen content can be adjusted at any time according to the combustion conditions to obtain the best incineration effect.
• Secondary combustion chamber
The temperature in the secondary combustion chamber is greater than 1200ºC, and the flue gas discharged from the kiln stays in the secondary combustion chamber for more than 2 seconds. Due to sufficient oxygen and even mixing in the secondary combustion chamber, dioxins and furans in the flue gas are completely decomposed. (DREE≥99.9999%)
• Waste heat boiler
Waste heat boilers are mainly used to recollect heat energy. While reducing the temperature of the exhaust gas, steam can be generated for use in the plant or used to generate electricity.
• Smoke handling system
The smoke handling system is mainly used to remove particulates, dioxins, furans, acid gases and heavy metals from the flue gas. Its configuration depends on the type of wastes being burned and the requirements for flue gas emissions. The smoke handling system we provide may include: quenching tower, dry humidification deacidification reactor, activated carbon ejector, bag filter, washing defogging tower, flue gas reheater, induced draft fan, chimney, etc.
• Emission continuous monitoring system
The content and transparency of CO, O2, CO2, SOX, NOX, HCl in the flue gas emitted by the incineration system can be monitored in real time.

Process system control
The operation of the entire incineration system depends on the coordination work of all equipments within the system. We start with the waste to be treated and then optimize the entire system through a dedicated heat-material balance program. We use a PLC-based control system throughout the incineration system that integrates equipment monitoring, safety interlocking, intelligent control and operational logging. The control system has a user-friendly interface that allows the operator to visually monitor and operate the entire incineration system. During the process, the composition and treatment volume of the waste are constantly changing, which brings great difficulties to the stable operation of the entire incineration system. We can provide an intelligent expert system for automatic control of the entire incineration system.

Technical Advantages:
1. Strong material adaptability
This system can handle a variety of solid, liquid, gaseous wastes and sludge, and barreled wastes can also be sent directly to the kiln for incineration. It can adapt to various wastes with a calorific value of 3 to 45 mJ/kg.
2. Clean smoke gas emission
This system has taken the world's most stringent emission standards into consideration since its inception. The system's flue gas emissions are fully compliant with the requirements of EPA, EU 2000/76/EC (or 2010/75/EU). In order to make our system emit lower concentrations of dioxin, we bring the flue gas into the secondary combustion chamber at a temperature above 1200 °C to completely decompose it. In addition, we use a dry-wet two-stage combined flue gas handling system to make the SOX, NOX, and HCl content in the flue gas lower, and even remove the sub-micron particles in the flue gas. In the future, we can fully meet the stricter requirements of emission regulations.
3. Low maintenance costs
The main equipment in this system uses a large number of mature and reliable equipment structures, which greatly reduces the workload and cost of equipment maintenance.
During use, only basic maintenance of the refractory material in the rotary kiln and the secondary combustion chamber is required. The special composition of refractory not only prevents the waste from coking, but also greatly extends its service life and reduces its maintenance costs.
4. Harmless slag
After treatment by the incineration system, almost all harmful components in the waste are burned and decomposed. The slag thermal burning rate of this system is <5%, and the harmful component destruction rate is >99.9999%. The ash produced by the non-slag type furnace is required to be solidified and buried in order to prevent the leaching of heavy metal components, and the ash produced by the slag type furnace is difficult to be leached because the heavy metal component therein is solidified in the glass body, so it won't bring any risk. In addition, the slag can be reused as paving material after the SPP treatment process.
