Device for producing wood charcoal and recovering wood vinegar and wood tar

Abstract

The invention discloses a device for producing wood charcoal and recovering wood vinegar and wood tar, which is composed of a carbonization furnace, an induced fan, a condenser, a low-temperature condenser and a flue gas filter. A retort technique is adopted and comprises the following steps: putting wood, husks and other wood raw materials in the closed carbonization furnace body, adding fuel into the combustion chamber, and igniting to heat the furnace body by using the added fuel so as to heat the raw materials in the carbonization furnace body and perform carbonization; leading out the flue gas byproduct by the induced fan, condensing the flue gas byproduct by the condenser to recover the wood tar, and passing through the low-temperature condenser to recover the wood vinegar, wherein the treated flue gas mainly comprises wood gas; introducing the treated flue gas into the combustion chamber, and combusting, thereby implementing good recovery; and after the carbonization finishes, treating the flue gas through the filter, and discharging the treated flue gas into air.

Description

technical field [0001] The invention relates to a device for producing charcoal and recovering wood vinegar and wood tar, belonging to the technical field of carbonization equipment. Background technique [0002] Under the condition of anoxic or low oxygen content, wood materials such as wood and fruit shells will degrade when heated to produce charcoal. The by-products include: wood tar, wood vinegar and wood gas. Charcoal is an impure amorphous carbon that maintains the original structure of wood and residual tar in the pores. It is widely used as an industrial metallurgical reducing agent and fuel, and also plays an important role in water purification and pollutant adsorption. Wood tar acts as a preservative, wood preserver and gap filler. The composition of wood vinegar is extremely complex, and its main components are water, acetic acid, methanol and acetone, etc. The main components of wood gas are carbon monoxide, hydrogen and methane, etc., and it is a renewable a...

AI Technical Summary

Problems solved by technology

There are many problems in this way, such as high fuel consumption, low thermal efficiency, long production cycle, and unstable product quality.

More importantly, the generated wood gas, wood tar and wood vinegar are not recycled, but directly discharged, causing great pollution to the environment
