With the increased of our country's economy, industrial or medical system of hazardous waste is also increasing, the hazardous waste chemical reactivity, explosive, corrosive, toxic, directly affects the environment, indirect effects of our human and animal health, this situation is gradually serious, which are caused the attention of the government, setting up special funds for hazardous waste treatment technology research, cement rotary kiln has achieved good results.
Through the study found that incineration of hazardous waste is implemented in many processing method of the best ways to reduction, harmless and recycling.
1. High burning temperature
Hazardous waste is mainly consist of hydrocarbon waste, hydrocarbon waste incineration temperature to 900-1100 ℃, other difficult to deal with waste is 1200-1400 ℃. Average temperature of the incinerator is only 850-850 ℃, materials sintering temperature can guarantee the cement rotary kiln stove at 1450 ℃, the gas temperature can reach 1750 ℃.
2. Large burning space
The specifications of our great wall cement kiln is generally 4.3 x 66 m cylinder, burning of space is very big, material under high temperature in a furnace, residence time is greater than 30 minutes, gas in the retention period of higher than 1300 ℃ is greater than 4s,it can ensure hazardous waste sufficient stability to burn.
3. Less Environmental damage
Cement rotary kiln system running under a state of full negative pressure, and it has a professional waste gas processing system; flue gas and dust will not overflow, fundamentally prevent the poisonous and harmful gases and pollute the environment. The burning of waste residue will directly mixed with cement clinker, realize recycling. Rotary kiln characteristic of sulfur absorption device make the sulfur dioxide emissions fully up to standard.
4. High production
Cement rotary kiln has high operation rates and low failure rate, so the production is high. With the development of the calcination technology, the daily output of cement rotary kiln is still in gradually improve, the future will be able to work more large scale hazardous waste incineration.
