Vertical-shaft tube carbonization furnace

Abstract

The invention relates to a vertical-shaft tube carbonization furnace, and belongs to the field of carbonization of carbon-containing organic matter. The carbonization furnace is particularly suitable for carbonization of agricultural straw waste, and is also suitable for carbonization of waste biomass including municipal sludge. The carbonization furnace provided by the invention has the following advantages: 1, a material is located in a pipe, so that the carbonization furnace cannot have uneven material falling and dead angles, and even if material attachment occurs, the furnace does not need to be stopped for cleaning; 2, a yield of wood vinegar can be regulated and controlled according to the market of the wood vinegar; and 3, a drying furnace and the carbonization furnace are respectively provided with one material adding machine, so that the possibility of gas blowby is avoided

Description

[0001] 1. Technical field [0002] The invention belongs to the carbonization of carbon-containing organic matter, and is particularly suitable for the carbonization of agricultural straw waste, and also suitable for the carbonization of waste biomass including municipal sludge. [0003] 2. Background technology [0004] At present, my country's agricultural production produces more than 1 billion tons of crop straw every year. In addition to direct return to the field, feed, energy, and material utilization, a large amount of crop straw is burned disorderly or discarded at will. Severe air pollution is one of the main causes of smog in autumn and winter. [0005] Tests have shown that after carbonization of 3 tons of straw, about 1.5 tons of straw charcoal, about 1 ton of straw vinegar, and about 200 Hm of pyrolysis gas can be obtained. 3 , about 100kg of biomass oil. [0006] Straw charcoal is a highly aromatic, carbon-rich porous solid particulate matter. It contains a la...

Problems solved by technology

[0009] However, there are still some flaws in this invention: 1. The material goes out of the pipe, it is easy to produce uneven feeding and dead ends, and material hanging occurs, and the furnace needs to be shut down for cleaning; 2. Although the air seal section is set, it is still not tight, and pyrolysis gas will occur The product escapes into the drying section, or the flue gas enters the carbonization section; 3. The pyrolysis gaseous products are all sent to the condensation cooling recovery system, and the output of wood vinegar cannot be regulated according to the market of wood vinegar
