Pyrolysis incinerator and air distribution system

Abstract

The invention discloses a pyrolysis incinerator which comprises a rotary kiln pyrolysis chamber used for heating, decomposing and preliminarily incinerating organic solid waste; the fire grate combustion chamber is arranged at the downstream of the rotary kiln pyrolysis chamber so as to fully burn the organic solid waste pyrolyzed by the rotary kiln pyrolysis chamber; and the secondary combustion chamber is used for combusting gas generated in the combustion process of the fire grate combustion chamber. According to the pyrolysis incinerator, organic solid waste is pyrolyzed and preliminarily incinerated through the rotary kiln pyrolysis chamber with high material adaptability, the fire grate combustion chamber is arranged in the downstream process of the rotary kiln pyrolysis chamber so that the organic solid waste can be sufficiently combusted, the pyrolysis incinerator can adapt to materials of various specifications, meanwhile, combustion is sufficient, and the combustion efficiency is improved. And meanwhile, the secondary combustion chamber combustion fire grate is arranged to combust gas generated in the combustion chamber, so that harmful substances are decomposed, and smoke reaches the emission standard. The invention further discloses an air distribution system suitable for the pyrolysis incinerator.

Description

technical field [0001] The invention relates to the field of organic solid waste treatment equipment, in particular to a pyrolysis incinerator and an air distribution system. Background technique [0002] With the revision and implementation of the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, the collection of industrial organic solid waste has increased substantially. Incineration is the main method of waste disposal in my country, which has significant economic, environmental and social benefits, and is also an important way to achieve a "waste-free city". [0003] In the existing industrial organic solid waste treatment process, rotary kiln incinerators or grate furnaces are often used for incineration treatment. Among them, the use of rotary kiln incinerator for the treatment of industrial organic solid waste can fully turn the organic solid waste, and has strong adaptability to various types of organic s...

AI Technical Summary

Problems solved by technology

Among them, the use of rotary kiln incinerator for industrial organic solid waste treatment can fully turn organic solid waste, and has strong adaptability to various specifications and types of organic solid waste, but it needs full air distribution during the incineration process, and The thermal ignition loss rate of the rotary kiln incinerator is relatively high; the grate furnace is used for the treatment of industrial organic solid waste. The air entering the lower part is fully mixed, the combustion efficiency is high, and the thermal ignition loss rate is low. It is necessary to make the organic solid waste stay in the furnace for a long time, and the combustion speed is slow, resulting in high heat loss
