Problems solved by technology

However, most of the existing waste incinerators use mechanical waste incinerators. This kind of incinerator system has many procedures and low work efficiency. Due to the complex mechanical structure, it is prone to failure during operation, requires a large amount of maintenance, and has high operating costs. Promoting apps brings some drawbacks
In particular, this type of waste incinerator cannot handle urban and rural light wastes well, such as urban and rural packaging, branches and leaves, weeds, crop straws and other loose and light wastes, which makes the heat energy released by combustion and the carbonization produced Both waste and ash cannot be fully utilized, harmless and low efficiency of resource utilization

Abstract

The invention relates to a dry distillation carbonizing treatment system for urban and rural lightweight wastes, and belongs to the technical field of garbage treatment. The dry distillation carbonizing treatment system comprises three parts including a dry distillation carbonizing kiln device, a dust-removal purification device and a wastewater circulation treatment device, wherein the dry distillation carbonizing kiln device is communicated with the dust-removal purification device by a flue positioned on a kiln body of the dry distillation carbonizing kiln; after the wastes are subjected to treatment of dust removal, washing and purification by heat energy and flue gas which are produced by dry distillation carbonizing, the flue gas is exhausted from the top of a chimney; wastewater flows into the wastewater circulation treatment device through a wastewater drainage pipe, is precipitated and filtered, and then is pumped into the dust-removal purification device for sprinkling the flue gas to realize circulation treatment and utilization of wastewater. When the system is used by combination with the steel-making field, high-temperature gas produced by dry distillation carbonizing can be used for drying steel-making auxiliary materials or generating electro-thermal energy, carbide can be used as raw materials for steel-making carbon additives and ladle covering agents, and ash contents can be used as raw materials in cement plants or used for preparing organic fertilizers, so that minimization, detoxification and resource of urban and rural lightweight waste treatment can be realized to a maximized extent.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a dry distillation carbonization treatment system for urban and rural light waste. Background technique [0002] my country has a large population. With the improvement of people's living consumption level, more and more urban and rural wastes are accumulated, and the amount of waste generated is very large. The current waste disposal methods mainly include landfill and incineration. Deep landfilling requires a large area of ​​land, and it is easy to pollute groundwater resources when buried underground. [0003] Garbage incineration is a relatively good treatment method. Garbage incineration can reduce the amount of garbage. At the same time, waste heat can be used for heating and power generation, making full use of waste resources and controlling secondary pollution to the environment. Therefore, in my country has developed rapidly. However, most of the ...
