Description

technical field [0001] The invention relates to the field of activated carbon preparation devices, in particular to a high-efficiency, energy-saving and environment-friendly carbonization furnace. Background technique [0002] The dry distillation of coal in an internal heating carbonization furnace has high requirements for raw coal, and can only carbonize lump coal of 50mm-150mm, which is greatly affected by raw materials. Moreover, a large amount of tar and sewage are produced during the production process, and the carbonized material produced has a high water content, which affects the quality of activated carbon. The current production of carbonized material is an extensive production, and the quality of the produced carbonized material is low. During the carbonization process, the phenomenon of burning and fixing carbon due to the entry of air not only reduces the carbonization yield but also affects the quality of the carbonized material. , At the same time, the high...

[0002] Coal carbonization using an internal heating carbonization furnace has high requirements for raw coal, and can only carbonize 50mm-150mm lump coal, which is greatly affected by raw materials

In addition, a large amount of tar and sewage are produced during the production process, and the carbonized material produced has a high water content, which affects the quality of activated carbon.

The current production of carbonized material is an extensive production, and the quality of the produced carbonized material is low. During the carbonization process, the phenomenon of burning and fixing carbon due to the entry of air not only reduces the carbonization yield but also affects the quality of the carbonized material. At the same time, the high-temperature gas generated during the carbonization process is not fully utilized, resulting in waste of energy and impact on the environment

The carbon monoxide, hydrogen and hydrocarbons such as methane released by materials during carbonization not only pollute the air, but also waste energy. Some need to build combustion chambers to solve the waste gas generated by carbonization, which increases the infrastructure of enterprises on the other hand. invest

Under the background that the fine coal in the low-temperature carbonization industry cannot be comprehensively utilized, the product quality is not satisfactory, and the environmental protection problem has not been fundamentally resolved, it is urgent to promote a reliable and stable equipment with a wide application range to the comprehensive utilization industry of low-metamorphism coal. Investing in an externally heated rotary low-temperature retort system in coal production areas can promote enterprises to obtain considerable economic benefits and open up a new way for enterprises to comprehensively utilize resources
