Split type carbonization furnace set

Abstract

The invention discloses a split type carbonization furnace set. The split type carbonization furnace set comprises a combustion furnace, a hot gas pump and carbonization furnaces, wherein the combustion furnace, the hot gas pump and the carbonization furnaces are sequentially connected through pipelines, the combustion furnace and the carbonization furnaces are separated, and three or more carbonization furnaces are connected in parallel in a process. Wood, fruit peels, straw and other biomass raw materials are put in the closed carbonization furnaces with a dry distillation process, fuel is added to the combustion furnace and combusted to generate hot gas, the hot gas is sent into the carbonization furnaces through the hot gas pump to heat the biomass, accordingly, oxygen-free carbonization is realized, combustible byproducts generated in the carbonization process enter a combustion chamber through the pipelines for combustion, the gas after combustion enters a chimney and is discharged into the air after being treated through a smoke filter, and environment pollution is avoided. The combustion furnace and the carbonization furnaces are separated, multiple carbonization furnaces are connected in parallel, each carbonization furnace can be operated independently, other operation is not affected, semi-continuous production of the carbonization furnaces is realized, the working intensity is reduced, and the equipment production efficiency is improved.

Description

technical field [0001] The invention relates to a split carbonization furnace group, which belongs to the technical field of carbonization equipment. Background technique [0002] Biomass raw materials such as wood, fruit shells, and straws will degrade 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. [0003] At present, the vast majority of charcoal production adopts the earth method firing process. In the earth or brick kiln, a part of the raw materials are burned to make the kiln reach the carbonization temperature, and then the furnace is suffocated. There are many problems like this, such as large fuel...

AI Technical Summary

Problems solved by technology

There are many problems like this, such as large fuel consumption, low thermal efficiency, long production cycle, unstable product quality, and more importantly, the generated wood gas, wood tar and wood vinegar are not treated and discharged directly, causing great harm to the environment. pollution

There are also carbonization furnaces used to produce charcoal. Generally, the carbonization furnace and the combustion furnace are integrated. It is operated intermittently, the operation time is long, and the production efficiency is low. Moreover, each combustion furnace needs a special person to operate, which is a waste of labor.
