Preparation method of organic volatile gas adsorption material for wood drying

Abstract

The invention discloses a preparation method of an organic volatile gas adsorption material for wood drying. The organic volatile gas adsorption material is prepared by activated carbon particles, lavender, fly ash, chromium nitrate, cerium nitrate, aluminum oxide powder and the like. The preparation method has the advantages that by subjecting activated carbon to acidification modification, a developed pore structure and large specific surface are provided, and adsorption capacity is increased; the fly ash processed by acid and alkali is used as the matrix to load Cr-Ce composite oxysome, a degradation space is provided for organic pollution, and organic matter adsorption and degradation varieties are increased greatly; meanwhile, lavender essential oil extract is used to increase aroma in the air during wood drying waste gas processing so as to optimize a working air environment; the preparation method is simple in process, low in cost, safe and stable in product, promising in marketprospect and good in application value.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a preparation method of an organic volatile gas adsorption material for wood drying. Background technique [0002] Wood will release a large amount of volatile substances during the drying process, and these substances will be discharged into the atmosphere along with the drying tail gas, which will have certain impacts on the environment and human beings. From the research on wood drying at home and abroad, it is found that the volatile substances produced during the drying process of wood can be roughly divided into two categories: terpene / terpene compounds and non-terpene volatile substances. The carbon framework of terpenes and terpenoids can be viewed as multiples of isoprene and its oxygenated derivatives. The exhaust gas discharged from wood drying kiln contains 25-30 kinds of terpene compounds, and non-terpene volatiles include organic acids, aldehydes, alkanes,...

Problems solved by technology

As a common adsorption raw material, zeolite usually needs to add silicon and aluminum chemical reagents to adjust the silicon-alumina ratio during its preparation and synthesis, and most of them need to add an organic template agent, but the synthetic zeolite is often a mixture of various crystal phases, and the purity is not too high. It also limits its use as an organic pollution adsorption matrix.
