Description
II
Изобретение относ тс к химической модификации древесины, касаетс установки дл обработки древесины, например уксусным ангидридом и может быть иопопьзовайо в деревообрабатывающей промьшшенности.The invention relates to the chemical modification of wood, a plant for treating wood, for example with acetic anhydride, and may also be applied in the woodworking industry.
Известна установка дл модификации древесины, включающа камеру ацетшшрованн , соединенные с ней бак дл подачи ацетигафующей смеси, дозатор, трубопроводы , систему отвода смеси в виде трубопровода, теплообменника, абсорбера и вакуумного насоса и устройство дл нагрева . Данна установка создана дл обработки древесных изделий уксусным ангидридом в жидкой фазе fl A known plant for modifying wood, comprising an acetal chamber, a tank for supplying an anti-tethering mixture, a metering device, pipelines, a system for removing the mixture in the form of a pipeline, a heat exchanger, an absorber and a vacuum pump, and a heating device connected to it. This unit is designed for treating wood products with acetic anhydride in the liquid phase fl
Недостатком этой установки йвл етс большой расход уксусного ангидрида дл обработки древесины. Кроме того, после ацетшшровани избыток уксусного аш дрида следует выделить из обработанной древесины, что осложн ет технологический процесс и продшшает весь цикл обработки.The disadvantage of this setup is the high consumption of acetic anhydride for wood treatment. In addition, after acetonation, an excess of acetic acid ash should be isolated from treated wood, which complicates the process and proves the entire treatment cycle.
Процесс химической моди нпсацш древесины происходит бс хее эффективно, если модафацирующий агент находитс в парообразном или газообразном состо нии . При обработке древеси1 Ы уксусным ангидридом в парообразнслл состо нии значительно со1фа1цаетс технологический цикл обработки, а также расход уксусного ангидрида уменьшаетс примерно в четыре раза, улучшаетс качест10 во модифшшрованной древесины.The process of chemical modification of wood pulping occurs more efficiently if the modifying agent is in the vapor or gaseous state. When treating wood with acetic anhydride in a vapor-state condition, the processing cycle is significantly reduced, and the consumption of acetic anhydride is reduced about four times, and the quality of modified wood is improved.
Цель изобретени - расширение технологических возможностей и повышение производительности.The purpose of the invention is to expand technological capabilities and increase productivity.
Поставленна цель достигаетс тем, The goal is achieved by
15 что камера ацетишфовани снабжена копьцевык разбрызгивателем, который соединен через трубопровод с дозатором, причем в нижней части камеры ацетипировани расположена камера дл нагрева 15 that the acetylphing chamber is provided with a spearbox with a sprayer, which is connected through a pipeline to the dispenser, with a chamber for heating in the lower part of the acetylation chamber
20 с трубчатыми нагревател ми, котора заполнена жидким теплоносителем.20 with tubular heaters, which is filled with a heat transfer fluid.
