High-efficiency environment friendly multi-layer carbon gas extraction method and extraction stove used thereof

Abstract

The invention discloses a method for extracting multilayer charcoal gas with efficiency, environment-protection and an extracting furnace used thereof. The method adopts a efficient, environment-protective and multilayer carbon gas extracting furnace, and charcoal making materials are heated from a first burning zone to a six burning zone to be prepared into charcoal; the flue gas generated in the first burning zone and the second first burning zone is collected through a flue gas pipeline; from the third first burning zone, the generated flue gas is led into the next burning zone. The invention adopts the zone heating and classified collection method, and the after treatment cost can be reduced. The invention also has the advantages that the flue gas can be sufficiently recovered, and the recovery ratio is high. The extracting furnace is suitable for the automatic flow process. The extracting furnace supplies good foundation for the automatization of the charcoal furnace.

Description

technical field [0001] The invention relates to a method and device for extracting charcoal combustible gas, in particular to an efficient and environmentally friendly multi-layer charcoal gas extraction method and an extraction furnace used therein. Background technique [0002] The original charcoal processing is to put the wood into the charcoal kiln for anoxic combustion, and the flue gas generated during the charcoal making process is directly discharged into the atmosphere. On the one hand, it causes serious pollution to the environment, and on the other hand, it also causes a waste of resources. These exhausted flue gases contain substances that can be made into various chemical raw materials and biodiesel, and can also be used as fuel, which has not been fully utilized at present. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency and environment-friendly multi-layer carbon gas extraction method and an extraction ...

AI Technical Summary

Problems solved by technology

[0002] The original charcoal processing is to put the wood into the charcoal kiln and burn it in the absence of oxygen. The smoke generated during the charcoal making process is directly discharged into the atmosphere. On the one hand, it causes serious pollution to the environment, and on the other hand, it also causes a waste of resources.

These exhausted flue gases contain substances that can be made into various chemical raw materials and biodiesel, and can also be used as fuel, which has not been fully utilized yet.
