After years of technical accumulation in large cement rotary kilns,Luoyang Building Materials and Architecture Design and Research Institute developed incineration rotary kiln equipment in 2010 for toxic and polluting wastes.Through our company’s continuous technical improvement, has formed a series of garbage disposal equipment.Incineration rotary kiln mainly consists of kiln barrel body, drive device, supporting device, baffle wheel device, kiln head seal device, kiln tail seal device, kiln head cover and other components.
Waste Incineration is a type disposal method in which municipal solid wastes are burned at high temperatures so as as to convert them into residue and gaseous products. The biggest advantage of this type of method is that it can reduce the volume of solid waste to 20 to 30 percent of the original volume, decreases the space they take up and reduce the stress on landfills.This process is also known as thermal treatment where solid waste materials are converted by Incinerators into heat, gas, steam and ash.
Waste treatment process
The incineration treatment technology of rotary kiln includes waste pretreatment system, incineration system, smoke purification system etc.The waste pretreatment system includes the waste pretreatment and feeding processes.The incineration system consists of a rotary kiln, second combustion chamber, slag discharge and control system.The flue gas purification system consists of waste heat recovery, quenching and dust removal equipment and acid gas absorption.
1. The equipment can burn solid waste, liquid and gas at the same time and has strong adaptability to incinerators;
2. The burning materials are rolled forward, and three heat transfer modes coexist in one furnace, with high heat utilization rate;
3. Build fireproof materials for different materials, so that the inner lining has a longer service life and low maintenance cost;
4. The driving mechanism is simple, and the driving mechanism is outside the kiln body, making the operation and maintenance of the equipment simple;The drive adopts variable frequency speed motor, which can adjust the speed of kiln body flexibly and control the material residence time.
5, longer retention time in a rotary kiln, and the high temperature of 1100 ¡æ, the hazardous waste pyrolysis, comprehensive emission standard;
6. Various forms of graphite seal and fish scale seal are designed for different hazardous wastes.Good sealing measures and negative pressure of furnace to ensure no leakage of harmful gas;
7. High equipment transfer rate, annual transfer rate can generally reach more than 90%, convenient operation and maintenance;
8. The anti-coking device is added in the rotary kiln to meet the processing requirements of different materials.
