Suspended vertical carbonization furnace

Abstract

The invention relates to a suspended vertical carbonization furnace. A furnace body is heated by a far infrared direct-heating type heater; a circulating cooling pipeline and a heat exchanger are arranged inside the furnace body; the circulating cooling pipeline is used for cooling and collecting products; the heat exchanger carries the heat to other work stations for use after exchanging the heat in the furnace body. A freely-retractable material receiving box is sealed in the bottom of the furnace. The carbonization furnace is capable of performing rapid carbonization and does not cause secondary pollution, and the heat in the carbonization furnace can be recycled.

Description

technical field [0001] The invention relates to the field of garbage treatment equipment, in particular to a suspended vertical carbonization furnace. Background technique [0002] With the rapid development of my country's economy, the expansion of city scale and the acceleration of urbanization process, the generation and accumulation of urban domestic waste in my country are also increasing year by year. In recent years, the annual growth rate of municipal solid waste has been 5%-8%, and the annual growth rate of waste in a few large cities has reached 8%-10%. The per capita daily waste production has exceeded 1 kg, which is close to the level of moderately developed industrial countries. The amount of urban waste generated in my country has shown a sharp increase, and the trend of growth is getting faster and faster. [0003] my country started relatively late in the treatment of urban domestic waste. For a long time, the main purpose of my country's urban waste ...

AI Technical Summary

Problems solved by technology

From the perspective of applied technology, foreign countries mainly use landfill, incineration, composting and other methods. The limitations of the above methods are: the treatment process itself will also generate a large amount of gas pollutants, and the energy conversion efficiency is very low, and it takes up a lot of land resources.

The traditional carbonization furnace burns and carbonizes materials through the combustion chamber, which takes a long time, consumes a lot of energy, and has low efficiency, and the smoke and tar generated must be discharged through the chimney, causing secondary pollution to the environment
