Rotary kiln incinerator is a pyroprocessing device used to raise materials to a high temperature in a continuous process. It is widely used in the fields of cement production, nonferrous metallurgy, ferrous metallurgy, refractory material, paper-making, chemical industry and so on.
Rotary kiln incinerator is usually used to burn pretreated and homogenized waste that requires size reduction, shredding, and manual sorting. The system consists of a burning layer of waste in a rotating cylinder.
Waste is transported through the furnace by rotation of the inclined cylinder.Compared to movable grates, the rotary kiln incineration has a smaller capacity and is mostly used for special types of waste unsuitable for burning on a grate, such as various types of hazardous, liquid, or contaminated waste.
Combustion usually takes place at temperatures above the ash melting point so that the ash is removed as liquid slag.
Advantages of Rotary kiln incinerator:
1. The main drive system uses the new AC speed governing technology. It has advantages of wide speed range, high efficiency, high precision and stable operation;
2. Rotary Incinerator is micro-negative pressure operation in the cylinder with low dust pollution;
3.Rotary Incinerator is even calcination, large capacity and easy to operation and maintenance.
Structure of Structure of Rotary kiln incinerator:
1.There are 2 to 3 fulcrums on kiln. It is easy to ensure the contact surface of rollers and kiln tires parallel to the cylinder axis during installing;
2.There are specific gap between the tire and cylinder. It strengthens the cylinder by confining tires after thermal expansion;
3.The supports use rolling bearing which simplified bearing structure. It reduces energy losses during Kiln operation and makes it easier to maintain and repair;
4.In order to convenient installation and commissioning, there is a kiln slow rotating devices to maintain kiln nonconventional running operation while main transmission system is under overhaul or other abnormal conditions which can occur cylinder bending and deformation during the cooling process.
5.The kiln uses mechanical or hydraulic catching wheels. They are high accuracy and reliability. The ridding rollers and tires are evenly wearing on the entire width direction and are handy adjustment.;
6.The kiln head and tail uses elastic flake radial contact sealing. It can fit the cylinder shape inaccurate and kiln deflection & axial movement. It has better sealing performance and reliability, longer service life and convenient replacement.
