Rotary kiln type incinerator capable of improving sufficient burning of garbage materials

Abstract

The invention relates to a rotary kiln type incinerator capable of improving sufficient burning of garbage materials. The rotary kiln type incinerator comprises a cylindrical kiln body and a plurality of harrow-shaped material throwing boards, wherein the cylindrical kiln body is arranged on a support with a power drive mechanism in an inclined lying mode and is driven to rotate, the harrow-shaped material throwing boards are arranged in the middle and on the rear portion of the inner wall of the kiln body, the harrow-shaped material throwing boards are cast by a refractory metal material and composed of harrow plates, the harrow plates are vertically arranged on a fixed installation bottom plate with limit assembling holes and provided with harrow teeth, and the top ends of the harrow teeth are in a buckling shape. During working, the harrow teeth on the material throwing boards are arranged in different matching angles such as middle, left avertence and right avertence, the garbage is prevented from sliding straightly downwards, turning over, being torn and loosened through shaking by force, the garbage slowly slides downwards and fully contacts with air and is continuously dried and burned in a loose state, during burning, slag is constantly grabbed and turned until the sufficient burning is achieved, ball-shaped, cake-shaped and shell-shaped insufficient burning wrappage can be effectively prevented, slag emission amount is reduced to the hilt, and effects of improving burning quality and efficiency, environmental protection and energy conservation are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment equipment, in particular to a rotary kiln incinerator capable of crushing and loosening garbage materials, helping to improve incineration quality and efficiency, and having energy-saving effects and enhancing the full combustion of garbage materials. Background technique [0002] At present, active hearth incineration is mostly used in the treatment of various hazardous waste materials, among which the rotary kiln incinerator is the most widely used type of furnace in the active hearth. The main body of the rotary kiln incinerator includes a bracket with a power drive device, a cylindrical kiln body that lies on the bracket and can rotate on the bracket. The kiln body shell is rolled and welded by carbon structural steel plates. The kiln body Refractory materials are laid on the surface, and the cavity of the kiln body is a waste material incineration chamber. The axis...

AI Technical Summary

Problems solved by technology

In practice, I have gradually realized that in the existing structure of the rotary kiln incinerator, there are no facilities on the cavity wall that are conducive to turning, loosening or tearing the garbage materials, so it is easy to happen due to the adhesion of garbage materials during the operation. In the case of incomplete combustion, the surface layer of sintered material wraps the internal unburned components to form hard spherical or granular objects, or forms a whole piece of internal unburned material wrapped by the surface hard shell, which can only be formed on the inner wall of the kiln. Waste that slides, cannot be turned or broken with the rotation of the kiln body, and then burns out

To sum up, the existing rotary kiln incinerators generally have disadvantages such as poor incineration quality, low work efficiency and high energy consumption caused by insufficient combustion of waste materials. Considering from the perspective of practicality and economy Both are less than ideal
