Continuous carbonization furnace for large-size wood material

Abstract

The invention discloses a continuous carbonization furnace for a large-size wood material. The continuous carbonization furnace for the large-size wood material is composed of a large-size wood material arranging frame, a preheating chamber, a carbonization chamber, a cooling chamber, a low temperature condenser and a smoke filter. The continuous carbonization furnace for the large-size wood material adopts a dry distillation technology, the large-size wood material such as wood is placed on the large-size wood material arranging frame, the large-size wood material and the large-size wood material arranging frame are taken as a whole to be subjected to each operation, automatic feeding and discharging of reaction raw material is realized by virtue of automatic control setting of the large-size wood material arranging frame and design of an automatic opener, the large-size wood material sequentially passes through the preheating chamber, the carbonization chamber and the cooling chamber and is preheated in the preheating chamber for removing moisture, oxygen-free carbonization is realized in the carbonization chamber, dry distillation gas is subjected to condensation recycling treatment and then returns to a combustion chamber to be combusted, the carbonized large-size wood material is subjected to forced air cooling in the cooling chamber, final combustion gas is discharged into the air after being treated by the smoke filter, and finally discharging is carried out, so that all the operations are completed, the whole process is completed under automatic control, and continuous operation is realized.

Description

technical field [0001] The invention relates to a continuous carbonization furnace for large-scale wood materials, which belongs to the technical field of carbonization equipment. Background technique [0002] Wood and other large-scale woody raw materials will undergo a degradation reaction when heated under the condition of anoxic or low oxygen content, and generate 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....

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

Carbonization furnaces are also used to produce activated carbon, but most of the devices that use large-scale wood materials to carbonize activated carbon are produced intermittently, with long operating hours and low production efficiency.
