Hazardous Waste Rotary Kiln

Description

By operating under controlled high-temperature conditions with excess oxygen, the hazardous waste rotary kiln ensures complete combustion and thermal decomposition of hazardous components. As a result, this process significantly reduces waste volume, minimizes harmful residues, and converts hazardous materials into stable ash suitable for subsequent stabilization or disposal.

As a core unit within a complete rotary kiln system, the hazardous waste rotary kiln provides continuous, stable, and environmentally compliant waste treatment for industrial worldwide.

Applications & Industries

Hazardous waste incineration plants
Chemical & pharmaceutical waste
Industrial sludge treatment
Medical waste disposal
Special industrial by-products

Working Principle

Hazardous waste is continuously fed into the kiln through a dedicated feeding system. The kiln rotates slowly at an adjustable speed and is installed at a slight inclination, allowing the waste to move forward under gravity and rotational force.

Inside the kiln, the waste undergoes high-temperature incineration at approximately 850°C, with a typical residence time of 45–70 minutes to ensure complete combustion. The rotary kiln precisely controls its rotational speed to maintain a stable slag layer of around 50 mm, protecting the refractory lining and extending kiln service life.

High-temperature air and excess oxygen create intense mechanical mixing and thermal interaction, promoting full combustion while minimizing ash generation. The rotary kiln then discharges the high-temperature flue gas and ash from the kiln outlet and directs them to a secondary combustion chamber, followed by downstream flue gas treatment systems.

Advantages



Large Processing Capacity

Hazardous waste rotary kiln equipment can incinerate solid, liquid, and gas waste with varying capacities and adaptability to different waste types.



High Incineration Efficiency and Heat Utilization Rate

The high-heat furnace of the hazardous waste rotary kiln incinerates large quantities of waste. The materials undergo three types of heat transfer, improving the heat utilization rate.



Adopt High Quality Materials

The lining is made of high quality refractory material, which has a long service life and is easy to replace, reducing operating costs.



Easy Operation and Maintenance

The transmission mechanism is simple, and the transmission mechanism is all in the kiln shell, so the equipment is safe to run and simple to maintain.



Hazardous Waste can be Achieved Harmlessly

The rotary kiln incinerates hazardous waste at high temperatures up to 1100°C, allowing for complete pyrolysis and partial burning of low-combustion-point waste.



Great Sealing Device

The hazardous waste rotary kiln has two seals: graphite and fish scale flake. They provide excellent sealing and negative pressure to prevent harmful gases from leaking out.
