Wood thermal modification treatment device

Abstract

The invention discloses a wood thermal modification treatment device. The device comprises a gasification combustion device, a heat exchange, a thermal modification device, a volatile organic compound (VOC) collecting device and a fan device which are sequentially connected through a connecting pipe. According to the treatment device, heat generated by the gasification combustion device is provided to the thermal modification device under the effect of the fan system to perform thermal modification treatment on wood, and VOCs generated by the thermal modification treatment of the wood are collected. The treatment device is simple in structure and high in thermal efficiency; plant source biomass, such as forestry and agricultural waste, remainders and wood processing remainders, serves as fuel, a heat source is provided for the thermal modification treatment of the wood through gasification reverse burning / reverse burning and efficient heat exchange, the device investment cost and running cost are remarkably reduced on the premise of guaranteeing quality of the wood undergoing high temperature thermal modification treatment, and discharge of the VOCs and thermal pollution in the wood thermal modification treatment process are avoided.

Description

technical field [0001] The invention relates to a thermal modification treatment equipment for wood, in particular to a thermal modification treatment equipment for wood which uses plant-derived biomass such as wood processing residues, agricultural and forestry wastes, and residues as fuel to provide a heat source for backburning. field of processing technology. Background technique [0002] With the implementation of the national natural forest protection project, the efficient and value-added utilization of artificial fast-growing forests has gradually become the focus of research and attention of domestic scientific research institutions and production enterprises. Over the years, people have attempted to modify fast-growing wood through chemical methods, and have achieved certain results. However, how to eliminate the harm to human body and environment during the preparation and use of chemically treated wood, and whether the chemically treated wood products can be acc...

AI Technical Summary

Problems solved by technology

However, the function of the back-burning furnace is single, which can only realize the back-burning operation, and cannot meet the process requirements of different temperature stages. The cooling problem is not considered at the grate, the life of the grate is low, the maintenance workload is large, and the thermal power of the integrated furnace is small. It cannot meet the requirements of industrial production; there is only a single air inlet and outlet pipe inside the chamber, resulting in uneven temperature and humidity field inside the treatment chamber, and the treatment quality is not high; the whole set of equipment lacks a collection device for volatile organic compounds, resulting in VOC emission and thermal pollution are serious
