High-efficiency environment-friendly value-added utilization method of bamboo sawdust

Abstract

The invention discloses a high-efficiency environment-friendly value-added utilization method of bamboo sawdust, and is used for overcoming the defects that because the conventional bamboo sawdust is abandoned, landfilled and incinerated, the environment is polluted, contents of the bamboo sawdust cannot be fully used resulting in a waste of resources, and bamboo processing benefits are affected. The utilization method comprises the steps: distilling the bamboo sawdust to obtain a bamboo sawdust oil gas and deoiling bamboo sawdust; separating the bamboo sawdust oil gas to obtain a bamboo oil, filling the deoiling bamboo sawdust into a carbonization furnace for heating to carbonize, and thus obtaining a bamboo carbonized substance and flue gas; and collecting the bamboo carbonized substance to prepare a bamboo charcoal powder, collecting the flue gas, cooling, separating, and purifying to obtain tar and fuel gas. The utilization method is mainly used for the bamboo sawdust, bamboo end heads, bamboo leftover materials and the like, and can also be used for other wood chips and similar materials; each ton of the bamboo sawdust can be profited with 2500 yuan, the value is added by more than 4 times, and the amount of less emission of carbon and other pollutants is about more than 0.005 ton. The bamboo processing benefit is increased by 10%, the utilization efficiency of bamboo resources is increased by 15%, at the same time, environmental pollutions caused by incineration and landfill of the bamboo sawdust are avoided, the cost is low, the practicability is strong, and the benefit is remarkable.

Description

technical field [0001] The invention relates to a method for utilizing bamboo chips, a by-product of bamboo processing, in particular to an efficient, environmentally friendly and value-added utilization method for bamboo chips. Background technique [0002] Bamboo processing such as moso bamboo produces a large amount of bamboo chips, bamboo ends and bamboo scraps. The existing utilization methods are burning, discarding, landfilling, or as boiler fuel. The disadvantage is that the burning of bamboo chips produces a large amount of smoke, The environment is polluted, and various beneficial components in bamboo chips are burned or discarded in vain, resulting in waste of resources, and insufficient exploitation of the utilization value of bamboo, which affects the potential improvement of bamboo processing benefits. Unfortunately, preliminary search results show that there is no efficient, environmentally friendly and value-added utilization method for bamboo chips at home a...
