Environmental Requirements For Small Rotary Kilns

According to the data of the National Environmental Statistics Bulletin of 2015, the national industrial hazardous waste production amount was 39.761 million tons, the comprehensive utilization amount was 20.497 million tons, the storage volume was 8.103 million tons, and the disposal volume was 11.74 million tons. The comprehensive utilization rate of industrial hazardous wastes in the country is 79.9%. A large number of hazardous wastes that have not been properly disposed of will cause environmental risks such as ecological environment damage, land occupation, soil pollution and groundwater.

At present, the processing capacity of pure hazardous waste centralized disposal plants is far from the disposal requirements, and the technology of co-processing hazardous wastes in Small Rotary Kilns has attracted more and more attention due to its advantages. Through the addition of hazardous waste pretreatment facilities and transformation materials to the cement production line. Practice such as interface, make full use of high temperature and strong alkaline working conditions in Small Rotary Kilns, long-term residence time of hazardous waste in high temperature state, elimination of ash-free slag, no need for secondary disposal. However, the incineration of hazardous waste in Small Rotary Kilns will also bring about the problem of increased pollutant emissions, mainly characterized by hydrogen chloride (HCl), hydrogen fluoride (HF), heavy metals, dioxins, etc. The issue of atmospheric pollutant emissions from disposal should be focused on.

In addition, heavy metals in cement products that are co-processing hazardous waste production also present a risk of environmental pollution during use. Therefore, in the process of co-processing hazardous waste in Small Rotary Kilns, the principle of whole process control should be followed, and the quality of cement products and the discharge of pollutants should be guaranteed under the premise of stable operation of cement system.

By controlling the types of hazardous wastes in the process of co-processing hazardous waste in Small Rotary Kilns, the environmental risks that may be brought about during the disposal of hazardous wastes are minimized. Under the premise of stable operation of Small Rotary Kilns, ensure the discharge of cement production, quality and pollutants, and realize the resource and harmless treatment of hazardous waste, which can not only solve the increasing pressure of hazardous waste, but also have a good environment and economy.
