Hazardous Wastes Incineration Rotary Kiln

  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.Technical performance comparisons of three types of furnace Slag TypeNon-slag TypePyrolysismaterial rangewide1widerelatively wide2   material status solid, liquid, gas solid, liquid, gassolid, liquid, gas  PCC temperature1200-1450ºC850--900ºC500--700ºCSCC temperature>1200ºC>1200ºC>1200ºC wearable material lifespanshortlonglongResidence timeshortlongrelatively longAuxiliary raw materialyesnonoAuxiliary fuelmorefewfewslag burning ratelowrelatively lowhighslag treatment  no3yesyessmoke emissionhigh NOxlow NOxlow   NOxoperating costhighlowlowNotes:1 Suitable for handling high-toxic wastes2 Suitable for handling organic wastes3 Can be used as paving material after SPP processIncineration 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 systemThe 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 kilnThe 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 chamberThe 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 boilerWaste 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 systemThe 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 systemThe 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 controlThe 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.                             graphical control interface(GUI)Technical Advantages:1.      Strong material adaptabilityThis 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 emissionThis system has taken the world's most stringent
